Workshop called today, they think its Front SAM issues, a very expensive part. and not 100% Guarantee fix.

Does the SAM needs any coding or it's a direct replacement? I just googled and saw few used SAM on ebay for very reasonable price.

How much did the shop quote for? I am sure they are going to get a brand new one.

I had never heard of a pre-fuse bloc failure until seeing 2 on this forum in the last year or so. The pre-fuse bloc provides power to both SAMs. Before replacing the SAM, it might be worth pulling the pre-fuse bloc and checking the fuses. Mercedes does not sell individual fuses if you find any open (blown), and the pre-fuse box is also expensive. But inexpensive replacement fuses are available online or from electronics stores.
