Folks, my golf's passenger side door module is now malfunctioning and we actually dismantled the module to open the door. I bought a China made replacement but the system controller seems not to recognize it and therefore not functioning properly. If you unlock the car the system will right away lock it back before you can even pull the door handle to open. We ended up troubleshooting the genuine module and was able to make it work thru modification of one of the spring but I don't think it will last so I need to buy the genuine door module. My problem is the exact part number to use to order the module. Here's what I'm getting for part numbers: 1) TDI Wiki - front right module: 3b1 837 016 bh , 2) Volkswagen.7zap.com - 6x1 837 014H; 6x1 837 014A; 3B1 837 016CF (I'm confused w/c of the 3 part#?) , 3) actual markings from the actual module - PA 6.6 30% GF ... VW logo FRANCE CM2 ... > P O M < 3D (the only markings I can see none similar to a part number). Ebay sellers have the VW genuine modules but I'm confused which one to get. Of course I won't have problem if I'll get the part from VW dealership but the price is way too high.
