Can anyone help me interpret this engine error code I got on my 02 1.9tdi galaxy: 18074 Valve for pump-jet cylinder 1 (N240) Electrical malfunction P1666 I had a peek on another vag forum and someone was saying the problem was with their Injector wiring harness. Can anyone give me any clues as to where this is and how easy it is to replace? Thanks, Ian

The MAF sensor does not affect air/fuel ratio - that is the job of the lambda sensor. Your rough running at idle is 99% certainly due to the disconnected pipework. Sorry, I should have mentioned that my galaxy is the 1.9tdi version on an 02 plate - minor details!! The rough running reminds me of a time when I hadn't replaced a clip correctly when changing the air filter, (throaty sound, lack of power and uneven idling) so I immediately checked every air and fuel pipe in sight. The garage did the same, but apart from a slightly loose pipe on the turbo found nothing and after tightening the turbo pipe the fault remained. Ian

My Galaxy has begun to play up. Usually after about fifteen minutes of driving it sounds and runs rough, but five or ten minutes later, at a steady speed, it clears up. Sometimes if I go straight onto the motorway, it doesn't play up at all. Other times, if I'm stopping and starting in heavy traffic, it won't clear until I switch the engine off, leave it for a few seconds and restart. After this initial hiccup, it will run perfectly well all day - I have driven for a further six hours without any problem at all. My local garage initially suggested a new air flow censor, but after plugging it into his computer and finding no evidence of a fault, was a bit more doubtful!! Any suggestions welcome! Ian

Thanks to everyone who added to this thread. Helped me diagnose and change my dodgy drop link in about half an hour. My wheel brace was a perfect fit for the 19mm nuts and being hollow allowed me to slot an iron bar down it to get the extra leverage to shift the thing. Total cost

Just bought one from my local shop (for local people!) made by Excel and it only cost
