Wonder about MB and BMW Diesel vehicles. I was looking at MB GLK-250
Diesel version when news broke out. Considering Diesel vehicle for next
new car purchase is on hold now. Also I am wondering about turbo charged
small engines on almost every cars, Ecoboost, Skyactive...,etc. Crap.

I had a Mazda MX6 with a turbo. One was supposed to let the engine
idle for a minute before shutting it off to let the turbo wind down.
There might've been some cooling also.
An oil reservoir above the turbo with a flow restrictor would've
eliminated that requirement but that would've cost the manufacturer
money.
Toyota's solution was a water cooled turbo.
