passat problems

[bethslad 1]

hi all

ill start by giving my apologies for this being non vr6 related, but my mrs has a 2004 passat tdi 130 highline and im having a mare with it, we had an engine management light on the dash with emissions workshop on the dash puter, after putting on a diagnostic machine it said we had an egr fault. ive replaced the egr valve and when she took it for a run last night it ran fine and cleared the fault on the dash. now this morning we went out and on cold start it was stuttery as hell and ran really rough, the engine management light was on again and we had emissions workshop on the puter again. now when the car gets to normal running temp it seems to run fine and after returning to the car after a trip shopping the car started, ran fine and the engine management light was off again.

again sorry for the non relation to the vr6 but this is starting to bug me as i cant get on with my vr's rebuild until ive sorted her car out.

thankyou

Might need plugging in and the original fault checking and clearing.

does this system do a reset when you take the battery off for 10mins???

hello again all thanks for the replies but I've found the problem its the injector wiring that goes through the engine as the injectors are under the rocker cover and its apparently a colon problem once the car has done a few miles so it looks like I'll be taking a Passat engine to bits :'( I might actually get my vr rebuilt at some point

Thanks again

Your better off removing the egr valve and see about having it deleted from your ecu they just coke up the inside of the manifold and thats not good for the engine.
