My dad's A3 (1.6 petrol) has throw up the EPC light and is juddering, not running smoothly as it usually does, whilst driving along, havent had a code scan yet. Was serviced 4 weeks ago. Any ideas? Lambda sensor? Hole in manifold?

Thanks

Any ideas?

Where do you start? the scan would be as good a place as any

Yeah just waiting to get my hands on vcds, is there any common faults on the 1.6 engine?

Lumpy tick over?? could be a coil pack?
