Vw probably went way thin for fuel economy when new. This is the opposite of helping engine life on a 20 year old car. How many nearly new different vag models burnt up oil and then engines  or was it poor manufacturing...

Quantum Platinum Plus here........... I get it from TPS who supply the main dealers.

I use the 5W40 and is recommended for these engines now, as the 5W30 is the longlife spec and these engines have now aged and tolerances are greater now.

Due to the low miles I do (3k per year) i change it every 6 months

I think the Quantum branded oil is actually Fuchs.

Hopefully it is that, that's a bit cheaper than a turbo

Is there any way I can test to see if that is the issue?

I used Quantum for quite a while as it was cheap and sold by the local VW dealer so I thought it must be ok.

Hopefully that should link you to the Castrol oil finder. Recommends 5w30 Alternative Recommendation  0w30 0w40

I would change the oil at least once a year regardless of mileage, I recently did my Scirocco was suprised on the price of oil these days I used Shell 5w30 from Euro car parts!

The middle code will be your answer possibly.

It's the N75 valve around the back of the engine that controls boost.
