Hello again! I have a problem with my tacho or with the signal for it. Since the expansion of the lowering the tacho is still or not completely. Every now and then the needle accelerates upwards and indicates a value that is not correct but at least. What I have already done: – Exchange of the dealer (no improvement) – Exchange of entire AI (no improvement) – Control of the cables on break Nothing helped. Since the function of the tacho is relevant for the check I must d find and fix errors. What else could be? Is there a magnet on the shaft for the signal? Can such a magnet go off or something like that? How could I control it? Switch gears? Thanks for your tips. Michi
