“Hey guys. A few weeks ago my 62k km 2016 F20 with the B38 engine threw an amber drivetrain warning after around 2 hours of highway driving.”source ↗
“They showed me that the marked pipe on the passenger side of the engine compartment (which I did some research about and it’s probably the turbo charge hose) was collapsing when the engine is revved to 5-6k rpm.”source ↗
