hi guys, looking for some advice. Recently bought an Audi A5 2008 3.2 multitronic. I've noticed that sometimes when I pull away, the car hesitates in going into first. The engine revs and then bucks a a few times and then engages into first. I. An prevent this by pulling away slowly, it doesn't do it all the time just on occasion. Has anybody got any ideas? Many thanks for reading
