Hello i am a happy owner of a 1987 300TD (turbo-diesel), but recently I’ve having some problems with the tachometer. Sometimes it's working properly, but mostly it doesn’t work. Without it the "kick down", the ABS and the "cold start function” wont work. I’ve tried looking for bad wires, but haven’t found any. Does anyone have any idea on where to start looking?? Could it be that the sensor is broken?? If anyone has experience regarding this subject please let me know.
I need you’re help!
