Services Performed
- Scanned all systems for faults and found codes stored in the DME. 102001 air mass, plausibility, air mass too high 120308 Charge air pressure control plausibility, pressure too low. Performed a intake smoke leak test and found that the clip for the charge pipe at the throttle was not in place which allowed the charge pipe to disconnect partially from the throttle body which caused the air volume to increase and the boost to decrease. Reinstalled the pipe and checked for damage and found none. Erased the faults and drove to find the turbo does build the correct amount of pressure but does so more slowly that a new turbo. >>If the low boost code returns then diagnose cause by manually testing the boost solenoid, vacuum supply, wastegate operation and exhaust back pressure. If all are OK then replacement of turbocharger may be necessary. >>The issue with the air mass too high is resolved by correctly fitting the charge pipe.
