If you have the correct SKC of the new clocks then yes they can be fitted.
You'll need someone with VCDS and a good understanding of how it works, look in the VCDS members section for people near you.
Lee.
Just to add, I think the VCDS way you only get one shot at coding the new clocks with the immo data. So its all or nothing.
I might be talking B.S as I've only used the k+CAN method but I'll have a read up on the VCDS method and report back.
