My daughter just had her 53,000 mile 2003 1.8T Jetta repaired (for a number of issues). They said there were codes for misfires in all four cylinders and that the oxygen sensor needed to be replaced (I assume it was the front one). The car has had an issue with trying to stall for maybe 30-60 seconds after startup.
If the oxygen sensor was bad, I'm guessing that it was killed by something upstream like whatever is causing the misfires.
Anybody got an idea for "most likely" causes of misfires and startup stalling issues in the 1.8T? I'm thinking coils or MAF sensor.
By the way, this is not a dealer service department, but it deals primarily with German cars so the techs are probably fairly knowledgeable. However, I suspect they are not as familiar with "most likely" causes as dealer techs are. Unfortunately the local VW dealer service department is predatory and untrustworthy.
Thanks,
Bill
