Hi folks, the middle brake light works on and off which I'm not too concerned about but the ridiculously intrusive beep that goes off every few times I brake is driving me mad!

Consensus online seems to be that you can't do anything about the noise and of course I'd rather the toplight worked without fail.

As it's intermittent I'm assuming a wiring fault. The flexi hose from the roof to the top of the tailgate seems the best place to start. Do i just prize that off? Never done that before and I don't want to make anything worse!

Any other thoughts or suggestions gratefully received.
