Hello, my central lock no longer opened. After researching something and the exclusion procedure I noticed that the working element is leaking in the driver’s door. When the engine is running it blew out of the cylinder well. So I ordered a new one from Mercedes. On the Internet I still found that there is probably an early and a late model of it but both should fit. But that’s not so. The white is the new and the black is the old one. The hole distance that I can screw the cylinder to the door fits, then the cylinder sits so close to the doorpin that the “blech” is much too long in between. Is there an extra sheet of metal that I would have had to buy with it? Does this just speak against a sheet metal to bend and use?https://data.motor-talk.de/…/20171106-201117-56079687043088560.jpg
