Hi all This is more of an FYI and if mods want to add it to the FAQ known issues thing then by all means. In the last two weeks the wipers started to operate only intermittently, indeed it got to the point only the drivers side would operate in what could only be described as a stuttering flap. Ended up at an auto spark who diagnosed that the 'pins' (imagine little strips of aluminium folder over on themselves) that held whatever wiring fed into the motor, had corroded. They simply stripped the wiring, attached new pins and the wipers are as new. This saved me from either a new ECU for wipers or more likely a new wiper motor at a minimum £110 (ebay) or £250 from Citroen.. I add this little tale so in case anyone gets told to simply buy a new wiper motor, and in this version of the c5 there are two of with separate motors, that maybe getting an auto spark for a closer look...in the end i paid £60...Hoy and Crowe Auto Electrics, Belfast
