2007-2014 Mercedes W221 S550 S400 Trunk Seat Lumbar Vacuum Pump 2218000248 OEM

Part Number 2218000248. Series W221. Model S550. Year/Year Range 2007. Naturally, my gently used vehicle was missing the Owner’s Manual. How do people live, right?. So i sourced this older, complete Manual set for my make and model.
