Unlikely it’s the pumps - probably the valve that gets corroded. Pumps are easy to disassemble and service (they suck the worthless foam “filter” in). Parts are available from partsouq for cheap. Whoever said check KDSS was on the moneyHow much would air pumps be? Sonar message?
Sellers have to be careful. For those of you that don’t have a BlueDriver, get one. Bluetooth OBD and it will tel you how many miles ago the CEL codes were cleared.
