That's almost as good as the £4,000 (no typo, or missing decimal..) that I was quoted to replace the broken circular cap on the centre console on my D2 S8 a couple of years ago. It was fixed in the end with a £10 replacement from A8 Parts of the whole central cartridge
Dealer quote (service supervisor) at the time - "it's an integral part of the whole computer system, so it'll all need to be replaced, and can't be replaced on it's own"
I didn't realise I looked that stupid...
