I just bought a used optically very well-kept SL55. Now the one day after yesterday’s pick-up at my garage and this morning shows in the display: ABC : car too low : on … went then but quickly away… hmm is that normal..? But now to my question: There is a switch in the footroom (something right behind the parking brake pedal) … a crunchy switch made of metal with two wires going away from it… what’s that for? what was it for? no difference… at least if the engine is running in the stand. I will make a photo here in this post later. Best regards Matthias
