Hi,

The engine on my 08 Passat 3.2 V6 Estate is misfiring and I'm hoping someone on here might have some ideas as to what it might be.

The misfire started recently (ironically I first noticed it whilst driving it to be serviced).

It was initially showing as a misfire on cylinder 5, so I had the coil pack on that cylinder replaced and all was good for a day or two, then the misfire reoccurred.
Taking it back to the garage I had the spark plugs and other 5 coil packs replaced. After picking up the car it's worked fine for a week then suddenly yesterday the misfire came back worse than before.

It was low on petrol so I've been out filled it up with BP Ultimate 97 and given it a blast down the local dual carriage way to rule out a dodgy bit of fuel left in the tank.

I do have an OBD dongle so I plugged it in and it's showing the following error codes:

P0300 Random/Multiple Cylinder Misfire Detected
P0305 Cylinder 5 Misfire detected
P0305 Cylinder 4 Misfire detected
P0305 Cylinder 6 Misfire detected

I can give the garage another call in the morning but I'm hoping one of the guru's on here might have some ideas?

Any help/suggestions would be greatly appreciated.

Thanks in advance.
