Hi I have a bmw 316 f reg and the warning light for the brakes is
continually on even after having everything done to do with the brakes it
has just past its m.o.t.yesterday, but as pointed out by the garage the
warning light needs to be sorted out so any help would be appreciated
TOP TEN SNOOKER
The warning light will either indicate low brake fluid level or worn out
I would assume you have checked the fluid level, so i would suspect that the
brake warning indicators need replacing. the common problem when these
warning indicators activate is that people change the brake pads but neglect
to replace the wear indicators at the same time.
The indicators work on a continuous circuit which, when the brake pads wear
to the minimum level, breaks the circuit by breaking the wire. you then have
no option but to replace the wear indicators.
Just one point of clarification... these should be different lights. I
have no idea what the hell an "F" reg is in Brit' speak (yes, I know it
means a model year, just not which one) or I'd try to help you with the
instrument panel indicator symbols. Check the light against the owners
manual. In other words, RTFOM!
If they replaced the brake wear sensors and the light is still on there
could well be a broken wire in the wiring harness the wear sensor plugs
into. So common a problem on E30s that BMW sells a replacement for that
section of the harness.
