Car jerks forward after a complete stop and lurches forward during move off
I have a 2010 A5 2.0T S-tronic.
Long story short, the car jerks when it comes to a complete stop (the feeling is like I have been lightly rear ended) and also lurches forward during move off in first gear.
Issues only surface after I have been driving for about 30mins-45mins continuously - with a warm engine.
When the engine is cold or during short drives, everything works perfectly and the car drives buttery smooth.
What could be the problem?
