My C240 was towed from the back rather than the preferred flatbed method. Now, my key fob works only 5% of the time and only when 6 incles or less from the sensor on the door handle. There are ghost messages on the control panel regarding the ESP, "info call failed", etc. And, my radio now has slight static on every channel. Has anyone heard of electrical malfunctions as a result of towing a vehicle from the back? Something has gone terribly wrong and I'm at a loss.
