Oil leaks (gaskets / filter housing)
Often reported
Oil leaks from the oil filter housing gaskets, O-rings, and sealing points are reported on the B48 engine. Leaks can occur on average mileage vehicles and usually require gasket replacement or realignment.
Engine Bay
Valve deposits (direct injection)
Often reported
The B48 engine is prone to carbon buildup on intake valves over time, leading to reduced performance and low-end torque loss.

Injector / high-pressure fuel pump failures
Often reported
