Hello all, new to the forum and new to MB. I have a 1995 E300D purchased without working cruise (I think W124 model). Worked intermittently for a couple of months, now dead. I took out the cruise control box and re-soldered all joints and cleaned contacts resulting with only temporary fix. Ebay has many cruise control boxes from other models and years that look similar to mine, without matching serial numbers though (usually for a C220). Will these other boxes that will fit actually work in my car or do I have to find an exact match?
