Brake Lights barely functioning

[PaulyV]

Apologies for what is close to a second post but I have a much clearer idea of the issue now.

It seems my brake lights are not coming on and off randomly when the car is at speed - they largely are not working at all. At standstill in the dark I was able to check them out this evening and the following occurs.

When depressing the brake pedal nothing, however if I tap it just slightly, the brake lights go on and stay on even though my foot is off the pedal...another tap and they go off.

Any ideas?

Check the brake light switch behind the top of the pedal.

I must have changed at least 6 with the same symptoms.

Yes, has to be the brake switch. Not the most reliable component on an E30.
Also check that the brake pull rod across the car behind the heater box is adjusted correctly, so that it lifts the brake pedal up to work the switch.
Rod should be adjusted to just take up all the slack.

Thanks for that. Not near my car but I assume that panel under the steering wheel into which the pedal goes comes off fairly easily?
