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.

No rev counter or rev counter erratic. This affects afterglow as well . Rev counter pick up front tip bent. Remove. put in vice take hammer an chisel and bent straight.(F)

No glow while ignition on when cold(F)
-Check earth wires going to glow timer control unit are connected on intake manifold.
No Afterglow after cold start- Plenty smoke till heat guage starts lifting.Check rev counter is working,Check temp sender (grey 2wire unit ) under intake manifold is connected and wiring to control unit.(F)

If immobiliser been removed and there is no rev counter, bridge the two white wires at the immobiliser plug, on some you must trace the wiring further to a relay and do some bridging there as well.(F)

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)

Pug 306, flashing Airbag light (F)
Fix : Wire to pretensioner is broken under the driver or passenger seat (usually the driver)

Citroen AX, Locking or windows faulty/intermittant (F)
Fix : Wires broken in the join between the door and body, drivers side usually

Audi and probably any VAG (most 2001 on) (T)
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.

Nissan 200SX S13, the updated model around L reg. This fault is specific to this year of production
Fault : Poor starting and rough idle
Cause: Crap quality valves have worn themselves down resulting in low compression. Full set of valves required.
New left old right.

Faded plastic headlights (F)
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.

These are 'bout bmw 2.0d to 3.0d (up 2003/4, same is probably after...)
(F) - accelerate above 3000rpm not possible - check maf and check inline pump under driver seat.

(F) - steptronic wobble when put in reverse - check engine mounts 2x, check trans. mounts x3
