Thanks for the quick reply. To be honest I've found the Coventry Nissan dealer bleedin' awful so far - they had it 10 days before they even opened the bonnet. They said they had a lot of illness, which could be true, but...
It's good to know that this sounds excessive though - it's what I thought.
The car is still in warranty, but I don't expect them to pay up because there are so many loopholes in the documentation. I expect them to wriggle out of it.
cheers
