I think if you're really worried about DI turbo issues, use RLI Bio-Plus in the fuel (1oz / 15gal - so a gallon lasts many miles) and maybe also LC20 in the oil.
That's been my regimen with my VW. No issues. Settled on this path after researching the old VW/Audi carbon buildup issues. Terry Dyson worked with owners and they found RLI oil and fuel additive to be the best treatment. I figured LC20 would be a good additive instead of RLI oil. (I run M1 as the cheapest VW502 sale/rebate price - much lower than RLI oil + LC20)
