All of a sudden, the speed indicator spins while driving. Turns suddenly to maximum and then minimum. Engine control light lights up on engine goes off. When the engine starts again, no problems with engine klauf. Revometer without function. Battery is disconnected. After reconnection, all hands go once to maximum and then back again.

Order date 17.01.2014 and delivery 31.01.20 14. Let’s see if this sensor revives my rev indicator…
