tricks and tips

[Meat-Head]

Hi folks, can we have a bash at some tips.

Hopefully in a few months time, we can do a cut and paste and have a print out, to keep, if members can edit there posts rather than new ones, yes i know i do it.

Can we if possable use this codings for entertaintment value

F = Found by yourself or work collegue
A= Found accidetly by yourself or work collegue whilst doing another task
R = can't remember
T= told by someone

-----------------------------------------------------------------------------------
Thanks to Drakov for pointing out the words spelt FART, this was a genuine 'error'
i would have put them in that order if i'd noticed it.

Cristec WOW good post, you have saved me a lot of time. Half of you post just
clicked instantly.

Drakov no offense, but what part of edit your post's not fresh didn't you understand?

^^TommyTee Good post, do you know if that data applies for al Vauxhalls?

Toyota Avensis D4d - Non Starter
----------------------------------------
Problem
----------------------------------------
Car not starting, No error codes, Car is turning over Ok, Battery is good?

----------------------------------------
Diagnosis
----------------------------------------
Give it a push start, you know clutch down, second gear, your "mates" pushing it from behind like Sly Stalone in the film Lockup lol

----------------------------------------
Solution/Cause
----------------------------------------
anywayz if the car starts on push, replace Starter Motor, even tho it turns good, it needs to build a good amount of pressure to start engine. (F)


---------------------------------------------------------------------------------------

Mini One- No Power Steering
----------------------------------------
Problem
----------------------------------------
The Power steering is non existent, Fuses are fine

----------------------------------------
Diagnosis
----------------------------------------
If you go into the Hydro Power Steering option in your scanner and get error message like "make sure ignition is turned on" even tho evry other ecu in the car communicates perfectly, or if there is a power related DTC

----------------------------------------
Solution/Cause
----------------------------------------
The fusebox in engine bay needs to be unbolted (make sure battery is disconnected!), underneath the box (abit awkward to get to there will be 4 bolted fuses http://t2.gstatic.com/images?q=tbn:HUMKGrokBuuqlM:http://www.bdbatteries.com/images/bolt_fuse.jpg (http://www.bdbatteries.com/images/bolt_fuse.jpg), cant rememba wich 1 (check autodata), unbolt it and replace (replace with same one if it is ok) put evrything back together and you'l find power steering is working like it never went dead, personally i have found there to be power issues, i.e too much voltage from altenator, removing the fuse resets the circuit (F)

[cristec]

I have just thought of some more

Rover 75 no start, or no rev counter and temp gauge, look in plenum chamber which houses pollen filter and ECU usually full of water, due to blocked drain, clear with curtain wire, this is also useful for clearing drain tubes on sunroofs.
Also if the water level has been very high it can also fill the glow plug relay, white box next to the ECU.
If removed and dried out usually OK.(F)
No start on petrol Rover 75, fuel regulator in fuel tank, comes undone it has a bayonet type fixing and the two halves twist apart, so no fuel pressure although the pump is running.
I usually refit and then drill a small hole, and screw a self tapper in to stop it happening again.

Citroen Saxo no heater blower or power steering, ignition switch faulty.
One of the ignition feeds has failed. (F)

BMW E36 no fuel gauge, sender unit in tank black wire broken, just re-solder.

Golf no rear washer although pump working, connector by NS hinge under headlining blows apart when washers used with frozen jet.

Mondeo leak from headlining by OS B pillar, and no rear washer, hose joint come apart on hose under roof lining.(F)

Escort Zetec hunting at idle, PCV breather valve faulty, it's on the front right of the engine near the top of the cylinder block, to prove it's the case of the problem, pinch the hose that is attached to it with a pair of pliers, if the idle stabilises then replace it (F)

S type Jaguar
No heat, full heat on one or both sides of the car, dual water control valve faulty, or the permanent 12 volt feed to the valve, centre pin of connector, if no 12volt feed, break is usually behind NS headlamp.(F)

No reversing sensors, first check control unit it's in the spare wheel well which fills with water and fills the controller with water.
If OK then put the car in reverse with the ignition on engine off, and put your ear on each of the sensors in turn, you should hear a ticking noise from each one, it is a very directional sound you might have to move your ear about a bit to hear the ticking, if one is not ticking it's faulty or it has bad connections to it, this applies to all cars with reversing sensors.(F)

X type diesel, poor performance and EML on, wires break to the MAF sensor, sometimes they break completely or sometimes they break internally,
where the wiring goes into the plug, if you pull gently they usually pull out from the plug(F)

No radiator cooling fan, earth connections under battery tray, corroded or broken.(F)

Will add more later.

Hi all,

F
I came across this today, Citroen Nemo diesel had been for a servicethey told him he was losing brake fluid !
Anyway we had to check for the loss today, the level was down to the clutch pipe, closer examination showed a small holein the clutch filler pipe, There is a thick wiring loom running from the top of the engine past the clutch pipe where it is chaffing .
one to watch for ?
all the best................mintoe

[vevepatronu]

All opel with 2.0 and 2.2 Diesel engines, the key flasher on the dash, in 4th or 5th gear and the car lose power at 3000rpm.... check the vacum rubber pipes because it cracks and get false air there, are almost elusive, you must check them all one by one, after will replace the one cracked will work like a charm :) (F)

no clocks wierd readings on temp,fuel etc check the brown earths on the round multiplug to the left of battery.
erractic reverse lights rear wiper and lock check the right side rubber boot for broke wires but dont rejoin them insert a new piece of wire as the old wire is now too brittle.
wipers slow then remove and lube the shafts on them..

vectra autos.
no gears then check the water level as the internal cooling pipe for autobox has corroded thru and filled up box with water, cost to fix ?2000

Zorgman is right about water in the transmission oil on
Vectras , but is also common on zafiras / astras mercedes it seems to be linked to vehicles using a

Freelander noise from the arse end!
Hi all,had a freelander in the workshop the other week with a wierd noise from the o/s rear,sounded like the wheel bearing was breaking up then completly changed with the road conditions into a sort of creaking,turned out the captive nuts in the body that the rear subframe mounts bolt into had came detached from the body due to metal fatigue,a bastard to find as it isnt visible with the subframe bolted up,unbolt the subframe and drop ir a few inches and the problem is visible,hope this is of use to somone,regards Paul m3vuv

[m3vuv]

susing out faulty wiring looms,ie fuse blowing! remove the blown fuse take a headlight bulb stick 2 wires on it with lucar male spades on them and stick the blades in place of the fuse,then when its in the fault condition ie drawing a heavy current the bulb lights up giving a visual indication of the faul occuring,its then possible to wiggle the loom at variouse points and watch when the bulb flicker or goes out,this gives a good idea where the fault lies ie chaffed wire etc,cheers Paul m3vuv

[m3vuv]

04 isuzu rodeo pick up,side lamps and stop lights comming on together,had this in yesterday,the problem was in the factoty fitted towbar electrics,the pin in the trailer socket was loose and had been pushed backwards so the screw in the pin holding the red wire(stop lamp feed) was shorting on the screw in the pin holding the black wire(side lamp feed),simple fix is replace the socket with a decent quality one and throw the factory piece of junk in the bin!!,cheers Paul m3vuv

Citroen Saxo no heater blower or power steering, ignition switch faulty.
One of the ignition feeds has failed. (F)

Just noticed this one so thought i'd add to it, also causes the HRW to stop working. Its caused by a faulty ignition switch. It can safley be rectified by bridging the wiring on the 2 pin brown connector at the ignition switch on the loom side of the wiring not the end that goes to the ignition switch. This bypasses the faulty part of the switch & was an official citroen bulliten. Takes about 5 minutes & you can then charge for a new ignition switch anyway.

Rover 75 ECU

It was mentioned in a previous post about that area of relays and ecu filling up with water. If you dry them out car generally starts. However, if it doesn't, remove ecu, remove lid clean all suspect connections flux them and resolder with soldering iron or hot air.
I fixed two like this in the same week, both had filled up ecu half way with water due to a heavy downpour and blocked drain hole. (F)

After replacing the battery or if its gone totally flat the auto close from the fob doesn't work anymore, nor does the auto up/down feature from the switch. Hold down the switch for 10seconds once the window has moved fully down, and again for up. This will reset the windows and enable the feature again.

common on clios and ford focus's, a rag and some cutting compound will have them clear and shiny in no time. you can use tcut but it takes a long time you are better off with genuine cutting compound like farcela G3. Also works on clock facias if you scratch it when removing.

Right guys, Im not sure if you check members profiles, but if you check mine you will see what my main job is.
I have one massive database of common faults and fixes, dating back to the seventies up to present day.
Not everthing is on there, but me and my 3000+ collueges strive to find faults and fixes/by-passes every hour of every day.
SO, if all else fails JUST AASK!!!!!!
I couldnt possibly add it all on here, it would take a lifetime.

Becm fault, no power from relay 7 fed by fuse 8. this does several circuits. This car had no power to the hevac display, no blower fans working even if i fed 12v to the circuit that lit the hevac & powered the cig lighter & radio. It would also keep the heated front screen on + other stuff that drained the battery.
I got a second hand becm, swapped out the lower board with the original so the car kept its immo & ecu info. Fitted it & all was ok. Hevac worked ok including the fans & no battery drain. However this board was not fully populated with relays so some circuits did not work & failed fuses were reported. I went back to the original board & removed the relay & tested it. It worked ok, traced the circuit to a shorted diode :)

Peugeot 406 HDI. Sorted out our third one of these in the last 6 months with the same problem. Came in on the end of a rope (not so unusual for a Peugeot) It was a non starter as the sound deadening under the carpet was pi55ed wet through. Carpet was perfectly dry on all occasions. Stripped all the trim to gain access to the swimming pool and directly under the accelerator pedal there is a multi plug swimming with all the connections well and truly ~~~~ed. done away with the multi plug and now everything is working. Knock the plug out the floor so it drains away. dont know where the water is comming from, leave that for someone else to find.

Car: Skoda 2001/02
Problem: electric steering works erraticly with steering wheel without pressure and light flicker
Solution: Torque sensor breakdown (F)

Regards all

[dik]

Found on the web, might be of use

CORSA ELECTRIC POWER STEERING

There are some common faults with the Corsa Electric Power Steering
that manifest themselves as one or both of these conditions

1: The car pulls to one side or is easier turn in one direction when
all else seems to be correct. E.g. Tyres equal, steering and
suspension geometry good, brakes and wheel bearings good, driven on
a straight and level road.

2: When turning, the steering will randomly seem to jam or stick for
an instant, and the steering wheel becomes suddenly heavy and then
reverts to normal.

Both of these can be rectified using a few commonly available tools
and less than an hour's work. By many accounts the solution from your
friendly Vauxhall Opel dealer is to replace the entire column.

FAULT DESCRIPTION

The most common problem by far with the Corsa EPS is caused by the
torque sensing mechanical components wearing with age leading to an
error with the torque sensor reading that gradually gets worse. The
situation can be rectified by adjusting the position of the torque
sensor to a new zero position.

1: Steering pulls or has a preference for one direction
================================================== ======
Full details of this procedure are available with photographs
elsewhere, but it is worthwhile mentioning now that you will need a
good degree of dexterity and a few useful tools to achieve it. Tools:
Medium sized Phillips screwdriver, T2.5 Torx bit, flexible driver,
small 2BA or 1/4" ring spanner, 13mm ring spanner.

Method:
Turn the Steering wheel to expose the two pop-on screw covers on the
retaining screws for the steering column switch covers, remove the
covers and the two phillips screws underneath. Remove the three
phillips screws underneath the lower steering column switch cover and
remove the cover. Remove the fuse cover and take out the two screws
beneath the fuse box to allow the lower section of the dash to be
pulled away.
On the lower right hand side of the steering column assembly just
inside the dash, there are two torx screws holding the steel cover
plate that protects the torque sensor. Remove both of these using the
flexible driver and T2.5 torx bit. Remove the cover. Before
proceeding, mark the position of sensor body relative to the steering
column body.
If you only need to reset the torque sensor position, you need only
loosen the screws to allow adjustment. If you need to fix the
sticking steering problem then the sensor must be removed. The torque
sensor is retained with two more T2.5 torx screws. The lower
retaining screw can be accessed fairly easily by pulling the lower
right section of the dash away from the metal structure. The upper
one is more difficult and may be slackened using the torx bit in a
small ring spanner.
Next, turn the steering column to gain access to the bolt that
secures the lower steering column universal joint to the rack spigot
that projects up through the floor. Remove the retaining bolt and
swivel the joint away.
If you have a short piece of plastic drain pipe or a cardboard tube,
slide it over the universal joints so that the steering column is
free to turn without jamming on anything (like your hands).

BEFORE TURNING ON THE IGNITION, READ ALL OF THIS BIT!.
When the ignition is turned on and the engine started, the EPS will
drive the steering column depending on reading of the torque sensor.
If you do this now, there is a chance that the wheel will be driven
continously in one direction. The column has a position sensor at the
top behind the steering wheel that will count 30 turns from end to
end before it jams. Check this before proceeding. Then turn the wheel
back to centre (15 turns from one extreme).
Now be ready to turn off the ignition if the next step causes the
wheel to spin rapidly. Turn on the ignition and start the engine. The
steering may spin rapidly, Switch off if it does. Rotate the torque
sensor fractionally and turn on the engine again. Repeat this process
until the steering is still when the engine is running.
Then, give the steering wheel a short tug in one direction and let it
settle, then do the same in the other direction. The wheel may
continue a little or might bounce back a little. If necessary adjust
the torque sensor position until the behaviour is identical in both
directions.
Now switch off, and check the steering centre position by counting
the turns, and reset it in the central position.
Repeat the torque sensor setting procedure to ensure that the
behaviour is identical in both directions. Adjust if necessary. When
you are satisfied that the steering is balanced and neutral turn off
the ignition, and tighten the sensor retaining screws.

Refit the Sensor cover, re-assemble the lower universal joint, refit
the covers and screws and test drive.


2: Random Jamming or "notchy" steering.
========================================
This fault is caused by the mechanical components that translate the
steering column effort (Control Demand) into motion that is
proportional to torque. Direction is inferred by the magnitude of the
torque being positive or negative. This mechanical translation is
managed using a slant-pivot coupling connecting the upper and lower
parts of the steering column that operates a sliding collar normally
held in a central position by springs. The motion of the slant-pivot
coupling is limited, and at either extreme allows direct coupling
between the upper and lower sections of the steering column. The
torque sensor detects the position of the sliding collar and produces
an electrical signal to represent the effort and direction of turning
the steering wheel. The EPS system then activates the motor that
drives the lower section of the steering column in the correct
direction to reduce the sensor reading to zero. i.e. No more turning
is demanded.
The problem occurs when the slant-pivot coupling or the sliding
collar bind or lock at some position in the travel. The components
are lubricated when built, but the lubricant degrades over time and
eventually hardens and dries where it is thinnest. When the steering
is turned slowly or by a small amount the friction at some points is
enough to make the coupling bind rather than slide, causing a zero
torque reading that effectively removes all power assistance until
the coupling moves. To the driver this seems like the steering just
got very heavy or jammed for an instant.
It is possible to reinvigorate the assembly using a mixture of
ordinary gear oil and a molybdenum disulphide based additive such as
molyslip or stop smoke.

Method:
Carry out the same procedure as case 1, then mark the correct
position of the torque sensor and remove it.
Inject no more than 15cc of the Oil & MoS2 lubricant mixture into the
void around the sliding collar and replace the torque sensor
carefully. It will be necessary to rotate the sensor until the sensor
actuator engages with the sliding collar correctly. Until the sensor
is correctly engaged it will fail to seat properly. Do not force it
into place or use the screws to try and pull it into position. The
sensor arm is biased to one end by a spring and it will have moved
when the sensor was extracted. Offer it into place and feel for the
situation where the sensor arm spring tension can be detected. When
it is in the right position it will just go into place easily and
then it can be rotated to the correct neutral position as previously
marked.

Before replacing everything else, start the engine and check that the
steering behaves properly. If it turns in one direction switch off
immediately and reset the torque sensor position by following the
procedure for case 1.

After lubricating the internal components, a few days may need to
elapse before the lubricant penetrates all parts of the coupling.
Over this time the steering will gradually become lighter and may
start to favour one direction as the coupling finds a new equilibrium
position. If this occurs it will be necessary to reset the torque
sensor position again

and a slightly easier option from one of the replies

"You don't actually need to disengage the steering column. You can use a multi-meter or do what I did and jack the car up so front wheels of ground and adjust sensor and turn ign on and see if it trys turninig itself to left or right. If it stays straight then jobs done. (albeit not the most scientific way it is much less work and even with a few attempts still less works than disengaging the steering etc)."

passat 2.0 TDI year 2009 , can't start the car , whene i turn ign ON i got nothing just klik klik klik klik.
with VAS you can't diagnostic nothing only some calculator.
after verefing i find the big relay in fuse box engine ( we have 2 relay one for air injection pump and the second for PRINCIPAL IGN CIRCUIT
i change this one and car start again :congrats:

Rear indicators faulty. Earth wire is too thin, remove and splice thicker earth wire (F)

[turbotecnics]

Some air mass and turbocharger pressure error codes, mil ligth one, poor performance, (only cars with electric egr) take plastic cover out of it clean everything and put some hight temperature grease. You get one new car, works on Opel and vauxhall too.

[tapiru]

Tks guys some of those was wery useful and honest I applied and work

[ecutuners]

Had a few of these come in not starting, dtc code for injection relay fault, the fault is a faulty piezo crystal injector, unplug each 1 and try to start, when you find the fauly one the car will run on 3 cyclinders

Brake lights won't work, you would think it was a brake light switch at pedal, some don't even have a pedal switch and use a pressure switch at master cylinder.
Wiring loom from the from the Abs pump runs past the nearside inner wing and rubs through a wire stopping the brake lights from working but still allows you to take the gearbox out of park.

Remove the washer bottle and nearside headlight to access the wiring.

Vauxhall Agila Z12XE 2001

Fault : Loss of all dash instruments

This due to a multi-plug connection problem behind the passenger side foot-well kick panel ( for a right hand drive car )
I think it was the white wire about 4mm . I just soldered the wires bypassing the multi plug
You would never think that could give a bad connection but it does.
I got this info from an AA guy while buying some spares he pulled it up from the AA database .

[MJRVR]

Corsa C intermitant non starting.
Bad connection behind the speedo cluster, can check by pushing on the clocks and seeing if that cures the problem.

If it does probably needs packing out behind, later ones had a wiring connector mod from factory.

this may help some folks!,had a bmw mini with low oil pressure at tickover when warm,it had the wrong oil filter fitted,the original was about 1cm longer than the replacment fram or coopers filter,even tho it was listed for the car!,it presses on a valve at the bottom on the oil filter housing,replaced the filter with the propper filter and problem solved,this happened after a service at evans halshaw lincoln who said the oil pump was ~~~~ed and would be ?700 to fix!!!! ****ers!

Just to give something back, today a 2002 Mercedes e class comes in on an AA wagon, non start, stuck in gear, Checked the obvious brake light switch and then the gearbox ecu for oil ingress both of which were fine.

There was no gear selection on the display, non talk to the scanner from the gearbox. so gear box fault initially it seemed.

Checked the fuses, then on the N/S under the big black cover with 4 screws in here are the ecu,s and a thing called the K40 on the K40 are 6 fuses and number 3 a 10A was blown, so replaced turned on the ignition the N came on the display for a second before going back to lines. The fuse had blown again, so this circuit had a short on it.

If you end up with this try unplugging the wire nearest to the engine/bulkhead "G" it is labelled on the k40 block, it as a twisted pair of wires, short gone everything works except the mysterious object on the other end of the twisted wires, Turns out to be the fan/cooler that blows air in to the ecu's

So reason for non start stuck in gear a seized blower motor :proud:

Hope this saves somebody a lot of time

Passenger tank scavenger not transferring fuel to primary side of tank. Gauges average both sides together. When the primary runs dry the scavenged side is full.guage reads 1/4 but car stops . Cheep solution. Remove float from scavenged side of tank. Tank never reads full but you all way know when you will run out of fuel. Or spend loads of money

Seat Toledo/Vw bora 99 to 04 no speedo, fuse for speedo is blown, also no reverse lights.

Wire for power to reverse lights broken and shorted to earth usually found where they run along the hinge to boot lid.

Also broken wires here can cause faults with boot lock solenoid.

Renault Megane's scenic fat ass shape, ignition switches on but no power to starter, and fan runs constantly. Broken wires can be found in loom that runs along front of battery. Open loom, usually orange wire is corroded (probably due to the very fine quality of copper wire they use in renaults!)

Problem: ecm failure in an M5 after battery flat.......sorted it but customer didnt want to pay full price. Solution: drove the rag out of it past customers house for two days.....customer paid:chuncky::chuncky:

[darrenhyland]

Had a 14 focus with keyless system. Battery went flat and the key fob had emergency key missing. Customer had two locksmiths out and both failed to pick open. As the car had tinted windows the customer didn't want to break glass and refused to drill the lock. Called me out and I tried the usual methods including jump cable to the starter lead but fob was not unlocking, lock wouldn't pic due to previous lockies efforts....wafers were stuck. I bagged it and got a rod in and popped key holder cover on steering column. Fished in the fob into the slot and with another rod pushed the start button. Result was doors popped. Synced the key fob and sorted new emergency key and lock. Sometimes you gotta think outside the box.
