Off topic but appropriate. As a retired engineer and a former turbo charged Audi (gas) owner I can assure you that after many premature turbo failures, AudiAG installed an electric after run turbo coolant circulation system which also ran in conjunction with the electric radiator fan. Promptly, premature turbo failures dropped to close to nil. That was back in the days (early 80's) where turbos were the newest latest greatest thing and a learning curve needed to be established. Heck, back then even high performance snow skis were labeled . . . . "turbo!"
