Convertible top problem

Hello, Convertible tops are frustrating and potentially expensive to repair, just to be up front about it. Your vehicle integrates the operation of convertible roof with several other systems, so diagnosis to identify why the roof will not open is needed. It may be as simple as a bad switch or fuse, but it could be as costly as replacing the regulator assembly or motor for the top. Aside from the range of possible issues, the cost of parts is also uncertain, as prices vary greatly from one distributor to the next, and so parts may only be available from the dealership or a salvage yard. The only advice to give is either attempt to make the diagnosis and repair yourself or have it diagnosed and quoted for repair at a few different locations. The price will vary depending on where the shop sources their parts. Independent European auto shops or independent Mercedes Benz specialty shops are going to know where to source the parts best.
