and the engine is ??
what happens when you try to start, all dash lights or not, engine spins or not etc...
more info.... needed...

[Dilksy]

sorry engine is a 2.0 tdi and when I try to start it the parking brake does flash. all other lights are normal. the AA fella put some "sniff" in the air intake (I guess its a can of fuel) and it started but as soon as he stopped spraying the engine shut off again.

[zollaf]

had you just filled up with fuel ?

[Dilksy]

I filled up the night before and it had just over 1/4 tank. I drove for 230 miles yesterday with no problems and it happened when i went to the shop last night. About 2 miles

[zollaf]

probably not that then. so many things it could be though, timing belt being one of the worst.

[Dilksy]

My timing belt was changed about 8 month ago. But i have always thought it was running a little rough from the change but the garage said it was fine

[Dilksy]

one thing i have noticed this morning is the EGR valve is making a buzzing noise and it has flattened the battery. it is as if there is contant power going to it without the key in the ignition!!!

[nevo]

Sounds like the egr valve is stuck open dumping exhaust gas in the inlet manifold.are you sure its the egr or manifold flap.

[Dilksy]

I am sure it is the EGR valve as i have had it off and cleaned previously. The sound is like a high pitched noise if that makes sense
