A connector on the engine wiring harness is not correctly locked or there is a problem with the pin contacts resulting in sporadic connection error. Any of the following Valvetronic faults may be stored: 136608 \- Valvetronic servomotor 2, position sensors, signal: Not plausible 136408 \- Valvetronic servomotor 2, position sensors, signal: Short circuit or open circuit 135808 \- Valvetronic servomotor 1, position sensors, signal: Not plausible 135A08 \- Valvetronic servomotor 1, position sensors, signal: Short circuit or open circuit These additional faults for bank 2 may also be stored: 135B10 Valvetronic servomotor 2, triggering phase U: Line break 135B11 Valvetronic servomotor 2, triggering Phase V: line break 135B12 Valvetronic servomotor 2, triggering Phase W: line break Any of the following consequential faults would be set as a result of the Valvetronic problem: 102902 air mass 2, plausibility: air mass too low 120408 boost pressure control: shutdown due to reaction 120908 boost control 2: shutdown due to reaction 107001 throttle angle 2 \- absolute pressure suction pipe 2, comparison: pressure too high Additional misfire faults are also possible: 140001 \- Misfires, several cylinders: injection is switched off 140501 \- Misfire, cylinder 5: injection is switched off 140601 \- Misfire, cylinder 6: injection is switched off 140701 \- Misfire, cylinder 7: injection is switched off 140801 \- Misfire, cylinder 8: injection is switched off"
