Identification CVT, 0AW Multitronic - chain WITHOUT sliding rails
factory new OEM chain WITHOUT sliding rails
part-no. on one chain link is 0AW 331 301 B - chain links are arranged admixed/offset starting and ending 1-1 layers than 2-1-2-1 and so on - chain has less strings and therefore the height is less approx. 34 mm - 75 link bolts (normal distance between bolts: 3,6 mm - but 25 gaps are 6,3 mm- due to that this chain is slightly longer than the one for 01J - IT IS VERY DIFFICULT TO DIFFERENTIATE - best is to check the part no. on the chain) - see also our product identification data sheet "IDS-VW/Audi-CVT-Chains" - sliding rails should also be replaced.
