Thanks Wammers... I've sent ya a private message after learning p38 had similar fault pre-christmas -before I bought it back. !.... Apologies Biastai for hi-jacking your thread
Have answered your PM. But as far as i recall when brake switch is dicky you only get ABS FAULT not TC lamp. Maybe you should be finding someone with proper diag like a Nanocom to find out what is going on.
