Common causes of fault code P2711 / 19143
A mechanical problem in the gears of the transmission might cause the transmission to change to default or “Limp” mode. Metal fragments might be attached to the magnets on the shift forks. The proper operation of the gear position sensor is affected by this. The mechatronics will change to default mode and turn off one of the input shafts and therefore half of the gears.
Our advice for a fault code P2711/19143
Verify that the magnets in the gear position sensors are free of metal fragments and debris. If debris is found, check the transmission for wear and damage. Verify the gear box oil filter as this can be clogged. In this case the oil filter will be bypassed which means that that he oil will not be filtered anymore. This can cause debris on the sensors. Clean the magnets and see if the fault code is still present
