Just an update on this for everyone, I took my car to a vw specialist who had a look at the cv gaiter, he could not find a split in it anywhere. He repacked it with grease and put new bandings on to keep it in place. Charged me £50.00 which I was more than happy with considering the dealer wanted me to fork out for a new driveshaft

, he said that if it had needed a new gaiter he could still have done the repair using the special tool to stretch the gaiter over the joint. Will be taking my car to him in future, also I will be writing to the dealer asking them what the f**k they think they are playing at. Avoid the main VW dealer in the Norwich area like the plague.
