Mercedes Repair Questions? Ask a Mechanic for Answers ASAP
Hi, welcome to Just Answer. My name is***** is correct. If you order a used SAM with the same part number there is no programming necessary. The part number is ***** to be found on the label of each of the SAM units. You can almost always find these used on eBay. I'd also check your local salvage yards. The prices at the local yards are usually less than you see on ebay.
Let me know if you need anything else.
