C5 (X7) keeps turning random lights on when parked

Post by dme88 »

My C5 (X7) keeps turning random lights on when parked. It turned the parking lights on, even tho the setting was set to Auto, and car locked. Have anyone experienced something like this?

A while ago, it also turned on the half-beam, so I though I must have pressed the light button by accident, but this has happened 2-3 times.

If you have fitted any aftermarket equipment (head unit or similar) - this can interfere. If not, then try a BSI reset:

BSI Reset / Battery Disconnect / Reconnect Procedure

If this does not cure it, you may have a fault with the Engine Fuse Box or the Steering Wheel Control Module that controls the lighting. A diagnostic should be your first port of call.

Solved the problem I Have replaced the fuse box under the bonnet and the fault has gone.
Could the BSI damaged the fuse box or the other way around

It was probably your fuse box all along and nothing to do with the BSI.
