Default Fault Codes/help

My 2001 TT has had cold start issues since I bought it 18 months ago. 2 Audi dealers have been no help. I've replaced the temp sensor with a green top and also replaced the battery. It is still running really rough when cold and I'm getting a CEL frequently. I finally bought a cable and VAG-Check for my IPAQ and here are the fault codes I'm getting:

16684 - Random Misfire Detected - Any Cylinder B 35-00

16885 - Cylinder #1 - Misfire Detected A or B / Blink 35-00

Allegedly, this Audi has had the coil pack recall. Currently I'm at 62k miles.

Any help would be appreciated.

Tim

Default I don't have that info handy.....

Maybe someone with better knowledge can answer. I'm not sure how a stock TT would run with those. I've got them on, but I'm fairly modded.

Default Thanks

New coilpacks on order.

FWIW, the VAG-Check is a pretty handy tool.
