1988 Mercedes 300 sel (126) speedo stopped working?
My speedo on the above stopped working a few months ago and then it worked a couple of times now nothing. Must be electrical?
Would love some advice before I take the car apart!
Thanks Michael.
Hi macheal the car speedo is electronic as you say so the norm is that the speedo drive on the rear of the gearbox has a wire on it and most times it will have a break in it check this out as the cluster unit never gives problems.You need to look for a round plug held in with a size ten bolt this is the speedo drive unit.
