View Full Version : As smooth as a bag of loose nuts and bolts.

My A4 Avant (V6 2.4 petrol) that, until recently, was as smooth a runner as a smooth thing on a smooth road (remember them?) is suddenly awful to drive.

It feels like it is missing when it pulls away and is def ‘running rough’ and getting worse.

I wondered if the lambda sensor is gone? Would it cause those symptoms? The engine warning light is on and it is sometimes flashing,

Unfortunately, I can’t get it to a garage for 10 days.

You need a code read first. Does it drive badly straight from cold?
