Services Performed
  • Replaced balance shaft assembly with MB balance shaft kit, old balance shaft has completely worn teeth off gear. After repairs, road tested vehicle, balance shaft fault codes(1200 and 1208) no longer appear, found codes 1203 and 1199 appear for left side exhaust cam and right side exhaust cam in incorrect positions. Found aftermarket cam sensors installed at these cams, swapped cam sensors from both exhaust cams to both intake cams, found fault codes move to intake cams. Replaced both cam sensors with known good used sensors, fault codes no longer appear. While driving vehicle to set emissions monitors, after several road tests, check engine light reappears for fault codes 2098 and 2092 due to fuel mixture at both banks too rich when idling. Reset fuel adaptations and monitored values, found values quickly go back to max value while idling. Determined mass air sensor faulty, installed new sensor and road tested vehicle, values now stay in spec and vehicle is running normally at this time.
