GLC63 No boost?
I have a GLC63 Brabus -19 that has no boost, the car has been driving fine til now and only has about 30000km. Boostgauge doesnt show any boost as it used and the car only has about 300hp
Have anyone had similliar problem? Turbos spool, no shaft play, no smoke. No fault codes.
Vacuum lines kinda hard to trace because of wiring loom in the way and no diagram to follow
