How do I troubleshoot a malfunctioning parking assistant on my BMW 7 Series?

I recently noticed that my parking assistant on my BMW 7 Series is not working properly. What steps can I take to diagnose and fix the issue?

First, check to see if any of the sensors are damaged or covered with debris. If so, clean them off and try using the parking assistant again. If that doesn't work, try resetting the system by disconnecting the battery for a few minutes. If the issue still persists, it may be a more serious electrical problem.

I had a similar issue with my 7 Series and after trying the above steps, I found that the culprit was a faulty control module for the parking assistant. If none of the above steps work, it may be best to take your car to a BMW dealership to have it professionally diagnosed and repaired.

Before taking your car in, you could also try checking the fuses related to the parking assistant. If they are blown, replace them and see if that resolves the issue. If not, then it's best to get it looked at by a professional.
