can a rear end collision cause sensors to short out

Hello, In the cargo area, below the right side cover, there is a fuse panel, a few modules, and, if I remember correctly, the battery. When you get rear-ended in a later model Mercedes Benz, if the parts are not physically damaged, the rainwater from the tail lights will surely destroy those electronics. This is a big job, and lots of electrical theory will likely be involved as electrical problems can be echoed through the CAN-BUS. Let me know if you have other questions, otherwise, here is a list of certified shops for your convenience. http://repairpal.com/mercedes-benz-within-10-miles-of-troy-alabama-36081
