2007 R32 Misfire Issues

[MJW]

Hi All

My friend has a 2007 R32 which recently developed a misfire issue. The dealer diagnosed it & we were told the oxygen sensor is faulty & $700 & 4 days later he got the car back. It was fine for about 2 weeks & same symptoms have re-occurred. The dealer is being very evasive about the fact that $700 has been spent with no benefit.

Can I throw out the question to those of you who know a lot more about VW's & mechanicals than I do to potential cause. My view is that if the O2 sensore fixed the problem for 2 weeks & has faulted again then something else must be causing that sensor to die.

Any help would be appreciated.

hey mate,

dont know much about the golfs, but I had an evo with the same problem.. O2 sensor would be rare to cause this, spark plugs and coil packs would be a much more likely issue, as this fixed my issue!!
goodluck

It definitely sounds like coil packs need changing. There was a recall on all R32 coil packs, I'm surprised your mate wasn't aware.

Thanks mate

Thanks mate. My friend only bought the car 6 months ago & is the second owner. His car goes in tomorrow for diagnostics. I will let you know the outcome.

Ok just an update for everyone. After changing the O2 sensor & the problem re-occuring VW then said it is one of the coil packs & replaced it. Problem has re-occured again.

Let's hope 3rd time lucky.
