My windscreen washers have stopped working, on my 2003 405 hdi. The washer pump is ok, as is the switch/stalk. The garage tells me the wiring goes thru the ECU. Is this the case? Does this really mean a replacement ECU? I am feeling slightly desperate ( ! ). Only other alternative i can see is to wire washer pump directly from a seperate switch. All help and advice would be really appreciated, thank you.
