Hi Guys

I have a VW Passat 2.0 FSi 2005 model (B6). The Exhaust Gas Warning Lamp comes on for a few days and says on, then occasionaly upon engine start will turn off. A few days later it re-appears for up to a week and then upon engine start may decide to switch off.

VW have said the VAG-COM error code is "Variable Misfire" and have sugested checking the oil pressure.

Apart from that, the car drives like a dream.

Any thoughts on this guys as VW appear to be guessing and for a seemingly well running car, this could turn out expensive.

Help appreciated.
