Customer Question

I have a BMW X5 e70 2007, the handbrake switch broke. I obtained a new switch,and fitted it. The handbrake will not work, and error message on dash. I had a BMW dealer carry out a diagnostic check, which they said was to the wiring having been cut at tow bar loom. I have checked the wiring, and it has been cut at the scotch locks, but can see no reason for it to cause the was not a problem before. Help ?.

My name is ***** ***** I am a professional here at Just Answer. I noticed that your question had not received a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.

If the wiring was damaged it can cause high resistance in the wiring causing this issue or may have corroded inside the wiring itself causing this issue here.I have seen this cause this fault.If you can re check the wiring that was cut for any faults with it needing repaired or replaced or try and make a better connection issue other then the scotch locks like solder connections instead to see if this then resolves the issue.If this is done or was done or re checked and found o.k. let me know so we can continue.

If more help is needed, use the reply tab to continue our conversation.
