My 2003 Passat has a noxious smell when I pull up to a parking space or sometimes when I stop at a light. It smells like burning oil or exhaust, but not all the time. The repair shop has replaced the oil pan, which was dented (by my 18-year-old son), replaced axle seal, and have replaced a broken and leaking PCV hose, but that has not solved the problem, and the don’t know what else to do.
I’d love to know if anyone knows how to fix this problem and also if you could tell me if you think that letting my son drive the car with these fumes is harmful.
Thank you so much!
