I posted here a couple of weeks about about the play in the botton UJ of my steering column. I couldn't see how to get the UJ off though, so I was forced to go to the local dealer. Actually the service bloke was very helpful....apparently this is NOT an unknown problem in the C5. The bad news is that the top half of the UJ is integral with the steering column, so the whole thing, or at least the lower half has to be replaced
The price for the job is £370 fitted, and I'm not sure that includes VAT, I was so gobsmacked I forgot to ask.
The problem with the inoperative rear screenwash is a faulty valve assembly, which is a mere £53 to supply and fit.
