Which AAB cambelt kit do I need?
For the AAB records currently in the Just T4s library, the important split is the engine-number sequence. The change happens between AAB 320126 and AAB 320127.
Gates K025323XS
Recorded for AAB engines up to engine number sequence 320126. Current library references include VW 074 198 119 A.
Gates K065323XS
Recorded from engine number sequence 320127 onward. Current library references include VW 074 198 119 A / J.
Where do I find the number?
The checker uses the numeric sequence at the end of the AAB engine number. Enter the sequence only, for example 320126 or 320127. Do not substitute the registration year for the engine number because this change point is engine-number based.
Before ordering
Always confirm the fitted engine code and the relevant engine-number sequence. Previous engine changes, rebuilds and non-standard parts can make a vehicle differ from its registration year.
