Hello Motortalk community! I’ve been having a problem with the speedometer for some time now with my Audi Cabriolet B4 year 1996 (speed meter, daily kilometers and mileage do not work). I now switched the dealer (2 times), measured all cables and changed the AI test by test. All these components work. With the dealer of the Audi 80 the resistance (Ohmmeter) has to commute between infinite and zero and in the gearbox provokes this up and down a magnet. m encoder attached in the gearbox and let the car roll a few meters and nothing happens at all. No on off but only constant infinite resistance. Did anyone have the same problem before and what exactly can be broken there? Do you have a plan from the gearbox?Do I have to change the whole gearbox? Thank you for your efforts and greetings, Manuel
