My 98 S500 usually a paragon of reliableness has been trying my patience for a couple of weeks
The boot/trunk door does not "suck" close as it should and the front doors refuse to close either (rear doors strangely trouble free)
I manage the situation by pulling & replacing Fuse #9 which re-sets the pump ecu and everything works again for about half a dozen closes of each
Im loathed to replace the pump with a used part as any on ebay for between £100 & £200 will be at least as old as mine now and will no doubt fail at sime stage
Has anyone tried replacing the pump ECU? the pump itself is actually extremley robust and should last indefinately its the 80's /90's electronics that seem to be letting the side down
Is my only option to fit a switch say to the side of the seat connected to fuse 9 and just flick it when it fails (it always works after the fuse us pulled)?
A new factory pump is £600 plus fitting
I absolutely love my car just completed a trip to the French Alps & back without a single blip thats 1750 miles on billiard table smooth french autoroutes & mountain passes, averaging 27 mpg
