Best take out an extended warranty when yours expires.
There are people that can repair the MCU's and VW Group will hopefully be required in Australia, New Zealand and other World Regions to accept there are Design, Manufacturing or material faults and like in 2012 with the DQ200 in some countries like China put a 100,000 mile / 10 year warranty on them.

The DQ381,s are not just used in 2.0 TSI or TDI's, also in some 1.5 TSI's FWD or AWD. Lots of them out there in VW,s, Audi,s, Seats & Skoda,s.
