Just wondering if anyone has a pump for the active seats on a w211 (52 plate) going spare, my motor has burnt out and all the carbon vanes in the pump have broken up. Maybe someone might know of any other pumps that could be used and where I might buy something that will do the job, I can't afford or justify the price Merc dealers want for what is a total luxury. The pump lives in the boot on the passanger side behind the trim, encased in foam rubber.
