2014 Mercedes-Benz CLA250: Anti-Theft Protection Gremlins
May 15, 2014
I started up our long-term 2014 Mercedes-Benz CLA250 the other day, plugged in my phone to charge it, and when I looked up I saw on the car's central screen: "Anti-theft protection activated. Service required."
This warning apparently applied only to the multimedia screen, as the car ran and drove as normal. However, I had no access to any of the controls for which this screen provides the interface: radio, navigation, etc.
Turning it off and on again turned up the same result. A key cycle did the trick, returning it to its usual self, and the glitch hasn't returned in the meantime.
