Current CLK 320 Cabriolet Former 1986 E 300D and 1959 190SL
Several times lately, I have gotten a warning that my S O S Teleaid is defective. A couple of times, the car tried to call for assistance. I don't have a phone installed in the car so I got the message that the call failed. This message was accompanied by a loud siren and no radio, etc. Usually, the "malfunction" resets itself after I turn off the ignition and restart the car once or twice. Any ideas?
