I have been having a bit of trouble with my 2.0 Tfsi, It started to stutter a bit under full load and has been in and out of the garage for the past month and a half. It has had all the usual things checked and also just had a service.
Firstly they have tested it and run the faults through the computer and gradually they have gone down from 7 faults to 3 faults, the last thing replaced was the maf sensor, which seemed to help for a short while and now it's back to as it was before with the engine management light back on.
The garage have been very good in trying to sort the problem out, but even they are struggling to work out what's wrong with it, the fault codes now seem to indicate a vacuum problem and when the car is idling and you take the oil filler cap off, there is a real sucking vacuum noise and the car starts to almost cut out.
If anyone can have a check on their car with the same engine and see if they get the same result I would really appreciate it? Or if anyone has any suggestions.
Many Thanks Steve
