I will soon be purchasing 1 of 2 Coupe quattros. Both need the timing belt. Is the special tool required to lock the crank pully for this car the same as the one used on the 10V model(#2084)? Is there a way to make my own tool? Does anyone out there have one I can rent or borrow? To anyone who has done this before on a 20V, are there any major pitfalls to expect? Tim ME
