Hi guys my a3 has a bit of a strange problem. When the engine is off cold fully like over night, when you start it up and drive, it is a bit jerky ocassionally, but once the car reaches slightly warmer temperature, near to operating temperature its fine. Any ideas what could possibly be causing this? Is it a misfire? I've booked in in for a service with audi anyways since the last service was done approx 15k ago, but any ideas? 2.0TFSI 2009 A3 Manual. Cheers.
