been trying to source a Gates serpentine belt 6PK1550XS which is recommended by Gates
But Sparesbox, Repco and others recommend and only stock the 6PK1555
So emailed Gates and.....
Quote "With the accessory drive belt, there were issues with this VW drive that caused belts to stretch excessively in a short period of time. This in turn can cause the belt to dislodge and in some cases get tangled up with the timing belt creating very expensive repairs. VW have been replacing the timing covers on these cars for sometime now to prevent the drive belts from interfering with the cam belt however they have not upgraded the accessory belt. We created 6PK1550XS with Kevlar cords and a shorter length to handle the elongation issue. So this belt is better than the genuine VW belt for this application."
