Hello all, I am in possession of an Eos Bj. 2013 and would like to retrofit in this the cruise control. Got the steering stick lever and control unit 5KO953569AE and installed. The steering stick lever works so far, except for the cruise control function. Unfortunately, the steering wheel control unit does not do it when the newly concerned is installed, since ignition lock has no function, so turning keys leads pretty much to nothing. The old control unit funktioniert einwandrei. Does anyone have any idea what this might be about? Greetings F.
