Hi there

My Audi A4 misfires when idle and the car shakes, it’s worse in the mornings but doesn’t do it as bad once warmed up. It drives fine when it’s warmed up! I’ve had it plugged in by 2 garages and no code errors are coming up at all. The one garage cleaned the solenoid and it ended up working fine for about 5 weeks, then over Xmas the problem came back. Just wondering if you’ve come across this problem before? Car runs perfectly with no other problems!

Thanks A Lot
