Greetings All, I have a 2005 Fortwo Brabus, recently, the above two warning lights have been annoying me. On start up, they behave as they should. They light up with all the other warning lights and go out as they should, they remain out, after engine start untill I apply the footbrake for the (usually) first time, then on releasing the brake these two lights light and remain on untill I stop the engine and start again, then the process repeats. For this to happen the car does not need to move under its own steam. IE, start the engine, all is well, gearbox in neutral, car not moving, apply foot brake, release brake both abs & esp lights come on. There are a couple of variations on the problem. On a hot day, yes when the sun is out, the ABS & ESP lights behave for maybe 10 miles, then they come on after foot brake application. If before starting the engine, I apply heavy pedal pressure and pump the pedal hard as well, the lights will behave themselves for a short time but then they light and remain on.
I've checked the fluid level in the reservoir and that's fine. The reluctor rings look fine. The tyres could be a problem and am working on another set to fit and compare. I am wondering though about the thoughts on the brake pedal switch being the problem. Can anyone tell me why this should be when, the brake lights and gear change work as they should. Also there seems to be some that suspect the YAW sensor? Would turning this through 90 degrees help with diagnosis? Any other thoughts on the problem please. Cheers, Ian.
