Ask a Volkswagen Question, Get an Answer ASAP!
Thanks for coming back. This fault has been with the Passat since I bought it about three years ago. It has never been a stopper and we have lived with it however it can be a bit worrying. Since I've had the car I personally have replaced :- front shock absorbers, both front drive shafts, all the brakes, the cam belt, accessory belt and tensioner and the sprag clutch in the alternator pully. This as well as servicing the vehicle regularly.
The car runs quietly and goes very well except for this fault. We have to tow our caravan soon so I though I would try your service to try to identify the problem before going to the VAG garage in Marmande. I realise it must be hard on the end of a computer line.
Me feeling is it has something to do with the turbo control system. Maybe wear or a leak causing low down low power instability.
The car has 235800 kms on it ( 147300 miles ) but it runs really well.
Your advice would be welcome, I'm sure someone has had this problem. I look forward to hearing from you. If you have a concern about the work done on the car, I was an aircraft engineer for 40 years.
If you need any more gen let me know .The engine code is a AWX.
Just wondered if yo have received my message
Hello Mike at just answers
What ia happening please.
I have not yet received any answers, but I have received a questionnaire
requesting feedback on your service. Any chance of a response.
In response to your questions.
The engine idles smoothly at all times.
I will check if the engine smokes.
Ref the turbo coming in. It appears to come in as it should but the engine hunts until it stabilises or one applies power at which time the hunting disappears.
I'll check the smoking issue but I feel it does smoke.
I took not e of your reply and examined the engine for loose pipes and joints.I also looke for the swirl frap system on the inlet manifold and the turbo which in some cases have these fitted.
I finaly removed the EGR valve having taked to a friend with experience of a similar problem. The valve was very heavily contaminated with carbon and gunge. I cleaned the valve of all the deposits and made sure all the moving parts were free.
Having refitted it the problems I had seem to have disapeared.
I'm not saying all is fixed but curently the engine no longer hesitates during pick up from stationary. If it does again start to play up I will go and see VW's
