I thought I should just revive this thread as a word of warning to others not to use cheap CV gaiters!!!
My car is back in the garage today for its THIRD new gaiter!!!
When I got home after having the first done I noticed grease in the wheel again, jacked it up had a look and the was an abrasion and a split in it. The mechanic was very apologetic as we assumed he had trapped it with a spanner and he fitted another free of charge.
This was fine for a couple of days, then friday while cleaning the car I noticed the wheel was full of grease again

Took the wheel off and this time the gaiter was covered in abrasions with about 3 splits in it! There was no way the guy was this careless. Thinking about my driving pattern last week the failures coincided with me putting my foot down on
the way home on a private road to about 120 or so. We therefore concluded that the gaiter wasn't up to the job and had to be expanding at high speed and catching the bottom of the shock or the bottom ball joint bolts, there is absolutely no other way it could come into contact with anything.
Today it's back in the garage to have a genuine VAG gaiter fitted and hopefully this will end my saga!!!
So beware all there are some cheap gaiters for sale out there that aren't up to the job on valvers (I should ask tonight what the brand was).
