Call the FCC Speed Sensors!
Has anyone out there ever had any speed sensor problems on their W124 E320?
I have a CEL with code 20, (speed signal not present) and a code 9 from pin 14 CC/ETA. I don't have any other codes that come back after clearing except these.
Arthur advised that I replace my brake stop switch, which I did. He also said that the speed sensor could be in the speedo unit. Isn't there also a sensor on one of the wheels?
I really don't want to replace the speedo if I don't have to. Any other suggestions?
Is this worth going to the dealer over?
Thanks,
Charles
