W639 automatic: the cluster shows R or N although the gear is D. What is the fault?
The cause is often in the gear lever position sensor or the lever module. Switching the car off and removing the key may restore function for a moment, but the fault returns. Removing the sensor requires dismantling the gear lever parts.
What does fault code P240C mean?
P240C indicates that the signal from the gear lever module is implausible. The fault is typically in the lever module, and replacing it has fixed the problem. The connector contacts are worth checking with a magnifying glass, as they may have poor solder joints.
Why does manual shifting (- D +) not work?
The likely cause is the gear lever unit or its sensor. The fault can be confirmed with a workshop diagnostic tool. The sensor can break, and it is possible to repair it.
