Long term maint. of the twin turbo

[clived]

My RS4 is approaching 100k miles on original turbos. The last 40k has been running at 450bhp. I look after them - warm up, cool down. I plan to do the same with the 135i, and don't anticipate any issues.

How long does it take to warm them up before driving? I live 3 miles from work, so i usually dont warm my jeep up too much before leaving, usually only on cold days.

dont warm the car up by idling. Drive cautiously until that oil temp gauge moves into the middle. Cars are too efficient these days to let them warm up by idling. You will do more harm than good.

If you don't have a oil gauge drive for at least 10 minutes. Warming up the engine by letting it idle is not the recommended way and it wont warm up the rest of the drive train. Drive like you're breaking it in for the first 10 minutes or at least 5 minutes after the water temp comes up. Oil takes longer to come up to temperature.

in the mid 90's I built a euro spec Audi S2 using an Audi 3B engine from a '91 200. It had a 100K miles when I bought it, and I tore it down in my basement prepared to bore the cylinders, install new rings and maybe pistons, certainly replace main and rod bearings. Instead, everything mic'ed to perfection; effectively zero wear. I refreshed all the seals and gaskets, gradually added another 10lbs of boost and it's gone another 100K miles with great reliability.
Contemporary engines are amazing.
