Hey guys have an 07 335xi. Check engine light came on and the code is P30FF turbocharger boost pressure to low. And i cant get rid of the light. I clear it and it comes back right away. Any help would be greatly appreciated. Thanks

The only tool worth using is a GT-1. Or you can get an Autologic but people who have both prefer the GT-1.

I wonder why he is diagnosing it himself, I'd expect there is still a warranty on that car.

Bring it to your dealer.

First step, check for boost leak
2nd, reprogram/encode entire vehicle to current i-level
3rd, replace wastegates or turbos
