Hi everybody,

I’ve had the car a few months and it’s done 104k but has full Audi service history. Sometimes when I start the car in the morning it starts fine but after about 10 seconds it’s starts to sound really rough and it feels like the whole car is shaking. It jumps between 800-1000 revs and It lasts about 20-30 seconds then it stops and sits at 1000. It drives great and no loss of power etc. I’ve had a diagnostic done and nothing showed up. Any ideas would be appreciated.

thanks.
