Do you have a ecu 88pins?

[Amine13]

can you explain meaning of 40V.NR

HI that means, the DARK plug (NR>> NOIR= dark (french word)); with 40 pins inside. it's mounted on bsi.

[pug_dari]

hi, have a problem with a 307 2.0hdi RHS 2002, always after a FAP regeneration give me that intermittent fault (have monitoring with often diagnostic), as a intermittent fault did show up with engine management light just found always at diagnostic with pps. Any solution, i have the ecu software for this car if needed.


thanks

Amine thanks...I didnt receive any answer so I start blind diging on this car..lucky for me pps is realy good tool for this brand so it help me a lot..I manage to understand conectors marks and after that all was realy easy ..also I buy few cd/dvd about pug cars..
main trouble was double relay near car ecu and aftermaket dvd radio..when I remove radio comunication is established with all modules only engine was dead folowing pps instruction I dismantle this double relay and see 3 diode 1n4007 was black...install new diodes and engine is alive finaly...firing on first key turn...

you know ..when you have schematic and understand conector marks all other is realy simple..I am in car electric busine since 92 but without schematic all this yob today is imposible to work 607 is first one what I work on it

P0246, reffering to lower turbo pressure than specified value, can be caused by several usual factors:

1. Faulty turbo solenoid valve (internal fault)
2. Vacuum leaks between vacuum feed and solenoid, or between solenoid and turbo actuator
3. Turbo internal fault (but this is out of discussion, as the fault is intermittent)
4. Clogged DPF (exhaust backpressure too high)

From my experience, I would go for the first 2 options. The turbo solenoid valve is in front of the engine, there are 2 or 3 solenoids there, one of them is for turbo. Try switching it with another one, from EGR or something, as they are the same, and check after that how it goes.

Sorry for the late replies, but ran into some kind of problems, been away from internet a while.

Alex

Already have checked all your suggestion regarding electrovalve (new valve) and vacuum pipes, non of this resolve the problem, have changed the exhaust pressure sensor for other issue, even that without no luck. I think this intermittent fault would be a software bug, as always happen at the FAP regeneration process.

Hope already understood your suggestions and my point of view is clearly explained.

Hi Alex, I have P307 2.0HDI 110HP, PP2000 shows that measured air flow is from 560 at idle to around 750 mg/impulse at more than 3000 rev/min. As I heard it should be around 250 at idle.
When MAF sensor is disconnected air flow is 506. What symptoms can occur if air intake is not measured correctly? I don't have big problems with car expect sometimes, not always it is rough on idle and while constant speed is maintained I feel little chokes, and maybe little greater consumption when it is compared with other Peugeot owners.
Also what is acceptable range for injector flow correction (e.g from -1 to 1). My readings after car is started are
injector 1: -1.22
injector 2: -1.45
injector 3: -0.04
injector 4 : 2.71
Thanks in advance

Higher MAF readings on idle can mean stuck EGR on closed position. When MAF is disconnected, ECU takes into consideration a limp mode constant value, this is why you have 506mg constant. As for little increased fuel consumption, this can be also caused by EGR being stuck in closed position, but can also be caused by injectors 1,2 and 4,which are out of limit. Injector 3 is ok. It is possible that injector 4,that has the highest correction applied by ECU, is altering the other injectors' corrections. I would recommend a fuel system cleaning with diesel purge additive (Wynn's).After that, check injectors correction again. Limit should be -1;+1.

Hi, i need security code from 1998 megane vin number VF1DA0G0C17361228 if possible. 12 digit for key programming. Thanks

I am dealing with Peugeot only.Sorry.

Are you reffering to forced regeneration process or normal regeneration that occurs while driving? Maybe exhaust backpressure is too high not letting the engine breathe enough, so turbo spool is too low, thus turbo not building enough pressure.

Thaks for reply, I have tested EGR by applying vacum on its vacum hose and I have heard knocking from EGR valve while motor was off, so maybe it is not stucked. I will measure air flow while I appply vacum to EGR manually and see is anything changed. Also I will buy that Wynn's addititve or similiar if I don't find it.

[alexs307]

Actually that Wynn's diesel purge it's not a pure additive, it's a cleaning agent for eliminating dirt and rust from injection system components. There is a special device, fitted with an electric pump, that you must plug to fuel pipes on the car, you must bypass the original fuel pump on the car (take fuse off or connect the fuel feed from fuel filter to the pipe that goes back to the tank). Your car should run at idle on Wynn's solution for an hour or so (has same burning properties like diesel fuel, but it also cleans the elements that is going through). I wouldn't recommend reving up the engine during cleaning process, it's not good. Leave it at idle.

Hi, i have a pug 207 2009 1.4 petrol
car is in bodyshop and was running fine
dashboard was stripped to replace airbag and battery was disconnected

now when you switch ignition on it says antitheft fault and eco mode

diag machine cannot comm with bsi, indicators, wipers arnt working

any ideas mate?

thanks

-Always happen on a normal regeneration on normal driving. When the generation starts have a bit of power lost which is come back in few seconds. I think this type of engine RHS is very rare and not very stable software, the car have at the moment 53k, and the problem has been discovered from 35k, all out of dealer warranty.
