Hi all
I have read threads on this forum re pse pumps and was wondering if anyone has come across my problem before.
The pump got wet by water getting in through third brake light which has since been fixed.At first the problem was that overnight the pump would drain the battery in the boot so that convenience functions temporarily unavailable would appear on the dash.After driving for 10 minutes or so the functions would return and be ok for the rest of the day .
I removed pump and took apart .There didn't appear to be any damage inside but I left it to dry out overnight and put it back on car and now it doesn't drain battery but I still get same message.The difference now is functions return one by one first parktronic then blower then heated seats but once the car is switched off it goes over same procedure and doesn't last all day unlike previously.
I am assuming that it must be problem with Pcb as car works normally once the functions return so is my best option to buy new one from mercedes or take a chance on getting mine repaired
Thanks Keith
