Hi guys,

Hoping someone has a suggestion as to the title post. Why are my brake lights on permanently!?

At first I thought it was potentially a simple fix with it being a faulty sensor/switch or something. This is not the case.

Garage (main dealer) have had my car for a week + still trying to identify the problem.

They did mention the possibility of it being a fault lying in the body control module or ECU.

Both of these have now definitely been ruled out after having both replaced and re-coded.


Literally losing my head over this!
Appreciate all suggestions/opinions.

Many thanks!

Anyone else able to help potentially diagnose this fault!?

Completely stuck at the moment.

This sounds ridiculous but I had this problem, it ran my battery flat. Once I got back home I realised my brake light was stuck on and this was draining the battery. I removed the fuse (the (break light went off) then put it back in and it's been fine ever since.
