Title: 16v big probs
Post by: mat-ryder on 28 May 2009, 00:35

My problem from last week has escalated and now i cant even start my car. Its fouling up the plugs almost instantly when trying to start. i replaced both problem relays a few weeks ago and vag com said i needed a new lambda so its had a new one of them recently too.
anybody know what would cause it to dump fuel like that??????
HELLLLPPPPPPPPPPP

ect sensor, wrong lambda sensor, be careful when buying a lambda theres a couple of different types

I had a similar problem with mk2 8v.  The ecu was faulty causing it to overfuel/flood and not start

Or possibly the fuel pressure regulator, wouldn't show as a fault on vag com

will the ecu fault show on vag-com?

I have tried swapping the ecu with another one but the immobiliser chip stops me from starting it. Anyway to bypass it?

Hi, with my ecu fault the fuel pump kept going rather than just prime itself prior to ignition.  Do you hear your fuel pump stop and start?
