I am the unfortunate 2nd owner of a 2004 Passat. Purchased it this year with 140k on it. The CEL has been on since June (3days after I purchased it) and despite my mechanics efforts to resolve all the issues he has just given up. It has lots of codes mostly vacuum leak related. Now I am noticing the car is burning oil and the codes the car has now is a vacuum leak code and the Turbo undercharge (P0299). Here are my questions:
If my car is burning oil (not leaking) it could be worn piston rings, gasket valve cover and anything else? Could any of those also cause a vacuum leak? The P0299 code, could that be caused by a vacuum leak?
I wanna love this car, but I can’t. I’ve spent too much on it and still have to spend more on it.
