The cvt tcm has been re-programmed by audi dealer for $160 after rebulit transmission for $3300. had to tow a ca for $70 to dealer just to get re-programing. took car on hwy and the acceleration didn't work. had to pool to side and called tow. found out the tcm has to be replaced and it is very common problem and audi is charging too much of money. could not find any part from anywhere unless audi. plus, the tcm is the one making the transmission break.
