Recently two things happened on my C8 at the same time:
- When I go into reverse my parking sensors sometimes give a continuous beep.
- My trip computer (rectangular display just below the speedo etc.) is sometimes blank and when it decides to start up the time and date are reset.
If I connect my Lexia I can see that (errors are from memory):
- There is an open circuit in my rear left parking sensor.
- The display has no permanent positive.
I am wondering if a short in a parking sensor can pull enough juice from the battery to occasionally stop the trip computer from starting.
