One more thing I would have. Topic Keyless Go. My said R320 CDI also has this feature, but with the drawback that it works with all doors except the driver’s door. My dealer has changed the door handle before, but this was not the problem. Did someone have to have the same experience? What was wrong with you? My confidant said that it might be the cable harness in the driver’s door or the lock. It is however that if I had a working Keyless Go T open and close, the driver’s door also opens and closes. Only the operation of the Keyless Go is not possible. Please ask for useful information to me (“as Konrad Tönz said at XY reference number”).
