Hello, I’m currently working a 2010 tdi with the cjaa engine. The codes are p0544 P16E0 U2100 car cranks but stalls out within a couple of seconds. The car is tuned and half way deleted. I Recently changed the cam shaft position sensor. Which fixed the issue for a couple weeks and it’s doing it again with a new cam shaft position sensor in it. Thought it might just be bad from stock. Took it to a shop and it threw the code for cam shaft position sensor. Any help is appreciated
