I've done some research, but haven't found any answer that pertain to my situation. Last night on the hwy, my car threw the code p0299, underboost condition. My waste gate has been rattling for the last few weeks on cold starts and decel. I'm 40 miles from home and would rather not spend money on a tow truck, since I just bought a new turbo this morning. The car didn't go into limp mode, would I be okay driving it home? Or should I get it towed? It's all highway driving.
