What updates do you expect? One simple question to you: would you ever buy a vw product ever? What is then the difference to a chinese vehicle? On one of those I would expect it to fail, but on a vw product? Unacceptable.
Regardless of where a vehicle is designed or built - sometimes the manufacturer gets it right and sometimes they get it wrong.
Considering how many 1.5TSI units were sold, this issue appears to have only affected a comparatively small portion of vehicles across VWG.
