Help me please. I bought this car with blown turbos and i forgot to check the codes before i pulled the motor.. now idk if i messed up or it was already like this.. anyway.. trac light is on, getting a cel with code p0346 i think. Cam sensor bank 2. When i replaced the turbos i did indeed do timing and cam seals, but i am sure my timing is dead on. The car is dogshit slow. My hyundai elantra rapes it. Lol. Im talkin 10 or 11 sec 0 to 60 times. Im guessing the car is in limp mode but it may be a boost leak. Im gonna do a boost leak test real soon but i really dont think thats the problem. I know that everything is hooked up. Im really new to the a6 but ive done tons of reading and im an experienced mechanic. The n75 throws no code and holds vaccuum to my tongue. Car runs no different with maf plugged in or not. Waiting for a friend with his crazy scantool since i dont have a vagcom.. i know i know.. sorry for the length of the post but being thorough never hurt anyone.

 

Made my own leak tester, turns out i had two fairly large leaks and fixed them. THE PROBLEM REMAINS. Im pullin my hair out. I got my cam sensor off and im awaiting a new one. If it still throws a code for the sensor it has to be my timing correct?! Overengineeredturdbox. The car starts and drives fine i just cant imagine it being my timing. I didnt do a compression test yet i will after my sensor is back on if the prob remains. Can one bad cam sensor cause the 2.7t to run this horrible? Anyone? Noobs.

 

probably not the timing. if the timing was off you would be misfiring and/or destroying your engine, depending on how much off it was.

almost sounds like something didn't get hooked back up/hooked up properly, when you put it all back together. do you have a boost gauge? did you get to someone with a vagcom?

 

Not sure where you found the leaks, but I would suspect the throttle body boot or, possibly, diverter valves. Either one but esp the TBB could result in loss of power. Sorry, cannot suggest how to test them.
