BMW 1 Series came in with a drivetrain warning light.
Ran diagnostics, found a swirl flap actuator fault. Tested it — motor was burnt out.
Took the manifold off while we were in there. Found heavy carbon buildup in the manifold and inlet ports and a worn shaft on swirl flaps causing an air leak on the manifold . Sorted it all while we had it apart.
New manifold, new actuator, carbon clean done. Running properly now.
