The Siemens boards are okay. One actuator needs new nylon gears. So can buy the gear kit from ebay. I suggest the metal gear kit from “odometer gears.” ECS Tuning has that, ebay has kits also. The actuators are around 90K
Top/first pic is the one with slightly worn gear. There is one or two teeth that are worn. Looks like a good option to install a new gear
