Hey, so i bought audi with automatic 7gears trasmission and some kind of magic started to happen, when i turn R on my rpm drops to 200-400 and engine almost stalls but it gets back pretty fast(rpms) so i did diagnostic check and i got P0011 something about camshaft position-timing over advanced or system performance(bank1). So can i drive or should i go to service asap? Because i cant go now, and how much will it cost to repay?
