Sounds to me like you're referring to the "Mixture-Control Unit", the "Air-flow sensor plate" and the "Air-flow sensor arm". First off, I'd suggest that you purchase the "Bosch Fuel Injection & Engine Management" book from Bentley Publishers. I got my copy from Performance Products (Performance Products4Benz.com) or 1.800.243.1220. The entire unit can be removed from your vehicle for bench repair. I have not had to do this operation yet, but it would appear that you need to disconnect all fuel lines and any electrical connections going to the Mixture-Control Unit, then remove the unit from your vehicle. The above referenced manual is invaluable in working with these units. Good luck!
