Studdering In Low Revs

[lestat]

Hi guys,

 

Ive a 2005 1.9tdi Galaxy and the last few weeks it has started stuttering (like dirty diesel).

Once you get into high revs (above 2000 revs) its ok but once the revs go down it shutters again.

 

The only way to stop this is to turn of the engine and restart (this could take 5 or 6 times)

 

You can also turn off the engine as driving and let it jump start as this will work also.

 

this happens from cold every time but once engine is warm it rarely happens.

 

 

Any advice would be fantastic

 

 

Thanks

 

Mark

I think its likely to be a faulty injector wiring loom and/or connectors.

 

Do a search on wiring loom for lots more info. Initial advice would be to clean the injector connectors. A new wiring loom cost around

I have this number for the AUY engine but check your engine code with VW dealer first. 038971600

HT leads (High tension) are the spark plug leads on a petrol engine, the AUY code refers to the MK2 115ps diesel engine.

The injector wiring and/or faulty injector will leave a fault code, you need to scan your car with Vagcom you can do this yourself by getting a lead off ebay and by using a laptop scan your engine module
