Parking Brake Failure

Hello all,

It’s great to be here and a proud member of this innovative community.

Im new here and just signed up as I want to seek some guidance on a parking brake failure on my F10 2013 which only appears in cold or wet weather. Throughout the summer it’s perfectly fine. The brake functions it’s just the warning light that keeps triggering.

I think I’ve found the problem so I am after the spec or BMW part number of the o ring on brake caliper housing (photo attached), which acts as a sealant to prevent moisture from entering the internals of the actuator.

Any help much appreciated.

Many thanks
