speedo / odo problem
 

My speedo & odo were reading 50% too fast, so I got a new speedo. Still 50% too fast. So the speedos themselves must be OK. What about the sending unit? Where is the it and is it replaceable? I have an 82 and I think this was the year they switched over to electronic pickup on the SL, but I am not sure. It's also possible that the P.O. was monkeying with the system as I removed a severed speedo CABLE from underneath the car! Any thoughts on what is going on here? Thanks.

A 500SL is a Euro model. Are your speedos/odos Euro or US versions?

Both speedos are p/n 107 542 66 01. My car is grey market, and the speedo's primary reading is MPH with the secondary reading in KPH. I'm taking this to mean they are US speedos, or do they use MPH in other parts of the world?
