Hello, any help would be much appricited. I have a misfire when idleing at around 1800rpm. Not too bad but you can definitely feel the car wobble. Then - the next issue, hopefully related...under high torque in 3rd say, at 4500rpm it judders violently/misfires for a second and then returns to normal. I've read a few threads on various forums about coil pack problems but nothing specific to the B6 S4. I'm getting it booked into a VAG specialist tomorrow but just wanted to see if anyone had any thoughts? Cheers, Antony.
