What is known:
1. Unpredictable failure mileage could be as early as 10k and latest one so far happened at 60k.
2. Full engine replacement is recommended because jumped timing ruins both the head/valves and the bottom end.
3. VW seems to be picking up the tab while car is under the 5 yr 60k powertrain warranty.
4. Happens to tuned and untuned cars.
5. 2009-13 all Years seem to be affected, no updated parts were installed as of yet.




Some Ideas for a fix
1.
Updated tensioner as such: Long term durability is still not proven.




2. OEM updated tensioner on the right... the retainer on the factory installed tensioner fails... causing the chain to skip timing.


THE OEM UPDATED CHAIN TENSIONER IS NOT ON THE RIGHT IN THESE PHOTOS, IT'S ON THE LEFT!
