Hi all, someone seems to have stolen one of the covers or blanking plates of the headlamp washers on my blue C5 Exclusive Estate (2006). Why, I have no idea.

 

The one fitted to the exclusive seems to be different from the standard one, which doesn't have headlamp washers - the fixing on the back is different. However, I need to replace it, but the if I buy on from the dealers (at £30) it will need respraying before fitting, as they only supply them in undercoat grey. Does anyone out there know of a blue exclusive being broken down for spares? Also, the washer who's cover is missing doesn't seem to work, can anyone tell me how to get at the guts of it to see what's wrong?

Yes! The replacement covers for the Exclusive models only come in pairs from the dealer and you'll need to buy the matching spray cans as well. Unfortunately, the covers fall off very easily, so don't assume that someone has nicked one. In 2005 I bought a new Exclusive model and within months, I'd lost one. I tried to get it replaced by Citroen but they didn't want to know. After fitting a new one, I passed a small zip tie through the fixings so they wouldn't come off without being cut.

 

As for repairing them - the water pressure forces the stalk out so maybe the rubber tube at the back of it may have a split. To get at it means a bumper removal job.

Ive lost 2 in 13 years. Unlikely someone has pinched it. It is a very vulnerable design and anyone trying to remove the cover without extending the jet first (by normal operation) runs a high risk of breaking the plastic tangs that attach it to the extending jet. Likely it's come off in use or due to a car park bump for instance. Ref the jet not working. Assuming the other is okay (ie fuse and pump ok), is the jet extending at all? Is any water coming out, even inside the bumper ? If the jet is not extending, is it misaligned with the aperture and being blocked by the bumper? It is a close fit and a slight bumper misalignment (eg from a bump) is enough. Is the extending jet (the bit the cover attaches to) intact? It is retained to the jet body by a small and weak internal star washer ( but it has to cope with a strong spring and high water pressure )- it can fail resulting in the jet internals/spring shooting out. If so, there is no choice but replacing the whole jet body - expensive part and requires bumper removal.

Assuming you have high discharge headlamp bulbs, be aware a non functioning headlamp washer is now an mot fail.

Note also, if the motor freezes, the fuse will likely blow. The headlamp washer motor is very much more powerful than the wind screen washer motor (to provide sufficient pressure to force the jets out) and much more expensive.
