Not Starting On All Cylinders

[Jayton]

but the search isn't very good on this particular forum software.

 

 

 

Anyway, lately the car has started but it feels like on 2 or 3 cylinders and then kicks in fully.

 

I'll do a VAGCOM in the morning (knackered after the brake change & BBQ) and see what that yields.

 

I hope it's not the injector loom :(

Hiya,

 

Right there could be several reasons for this on a diesel:-

 

1. Fuel Pump - unlikely

2. Blocked fuel return pipe - definently not.

3. Poor compression - possible - needs a rebuild if it is.

4. Glowplug not operating properly - bung in a new set - 90% likely

5. Diesel injectors - if bunging in new glowplugs does not work then get the injector spray pattern checked - if you have done over 80,000 miles get this done anyway. Getting new injector nozzles will dramatically improve an older diesel car.

6. It is unlikely to be wiring related as diesels use so little electrical trickery.

 

Happy days

Cheers mate,

 

The car has done 144k miles :( I guess it's time for a nozzle test, how much are they roughly? I'll be having a full service at the end of the month, I'll also have them change the glow plugs (I can't be arsed to do anything on the car anymore as it seems I break it when I do anything to it!).

 

I cleared the codes and took it for a drive, tripped out the turbo (sticky vanes...) and got back with the following code, as a result of accelerating too much with the engine still quite cool (3rd gear @ 3k rpm it tripped out)

 

Control Module Part Number: 038 906 019 BF

Component and/or Version: 1,9l R4 EDC G000SG 1088

Software Coding: 00002

Work Shop Code: WSC 00020

1 Fault Found:

17965 - Charge Pressure Control: Positive Deviation

P1557 - 35-00 - -

 

 

 

I'll rescan it the next time it doesn't start up properly and see if there are any codes.

You should be able to get all the injectors pressure tested for free. I would suspect new nozzles
