Well I was having some random problems with my car, took it to one renault garage and they said they had tracked the problem down to the UCH, £400! So I thought ok, if its going to solve the problem, thats fine. But it didnt at all, by this time they had already had my car two weeks without a courtesy car, so I decidedid take it to a different renault, where they said the same and replaced it under warranty. And as soon as I drove off the forecourt I had the same problems, so I took it back, they had it for another week and then found out that someone had put the wrong spark plugs in, and they were misfiring and f*cking up the computers. So now all those problems are fixed, but I have this little problem with the wipers.
And in the ed they said the UCH never had to be replaced at all!
But also, I argued about the UCH and got a refund, so if I now ask them to check the configuration, will they charge me?
