I got this car for really cheap last nighr and plan on fixing it. The guy I got it from swapped in a new motor but now the trans doesn't engage at all. On the way home from towing it I stop by a parts store and put a scan tool on the car the codes came up P0614 I belive this one is saying wrong gear ratio And P0730 which is mismatch ecm/tcm. Anyone know where I should start at????? And by the way this is my first audi !!!!
