Hello Had a similar problem. 2003 Citroen Pluriel - one of the plastic 'trams' - a piece of black plastic 2cm x 2cm x 2cm cracked. As a consequence. the roof now doesn't close properly, meaning it leaks rain in and also billows up when driving at speed, meaning you have to wear ear plugs. Took it to my local Citroen dealer expecting just to have to get the broken tram replaced (looked like a 15 minute job). Got told that I would need to have a whole new roof put in - inc. rear glass, tonneau, etc. the whole shebang) because simply replacing the tram was an ineffective fix. Got told by the mechanic (a Citroen employee) that they see C3 faulty roofs pretty much on a daily basis. He told me the new roof would cost me £2K + £500 min labour to install. Again, he said he would try to get the parts on goodwill, given its an obvious design flaw, and absurd for a customer to have to spend £2k to replace a piece of plastic with a cost price of max £10. But Citroen said no after two weeks, claiming it was out of warranty. This is a car that's done 60k km since new, i've owned it since new and serviced it continually at Citroen dealerships. Obviously I think Citroen have totally abused the customer / manufacturer relationship here. I'd never buy another one of their crap cars and I'm going to make sure I tell anyone who will listen about this incident. Anyone else with this problem, please PM me, and I'll share details. We need to get some action on this cover-up / denial by Citroen (have a letter from Citroen UK claiming they don't know anything about faulty roofs on the C3 Pluriel, despite the conversation I had with the the mechanic who told me he was putting goodwill claims in for new roofs on a daily basis). Disgusting, shameful company. I hope the recession bites them hard for their disingenuous behaviour.
