S500 Speedo and fuel consumption gauge problem

Hi Folks,

1994 RHD S500 Coupe.

My speedometer started jumping all over the place for about a week then stopped working altogether. The Odometer has also stopped along with the Fuel Consumption indicator gauge.

Any ideas what has gone faulty to cause this?

Thanks

Douglas

Speedo signals are derived from left/right rpm sensors located near front wheel rotors (discs). Can be disturbed in error when brake servicing is performed.

Without speed signal, odometer & fuel consumption calculations will not be performed. Also cruise control, if fitted.

Thanks, for that info! I also just read about some additional fuses at the rear of the engine compartment where you have to undo 4 Allen keys to get at them and one of these also seems to have links to these items so I will check this too!
Many thanks

Douglas
