No harsh shutdowns. After leaving the freeway, I go about 2 miles through residential /25mph streets.

I have had new turbos installed twice and have had the turbo rebuilt twice. One other time MB provided a turbo as part of the recall to remove the football filter. I do not know if that was rebuilt or new since the factory/dealer covered it in the early 1990s. The rebuilt ones were guaranteed to have been balanced and tested at high rpm.

I do not know about IP timing but this car has gone through several of those as well. The turbo was leaking a small amount of oil but I would not call it bleeding. Also, the waste gate was not moving but it did free up.

By inop, I mean that when accelerating on a freeway on ramp, the car gets up to ~40mph and no faster although the engine rpm can still go up. The only way to shift is to back off the pedal and wait for a very quiet shift into the next gear up. After that shift, the car can slowly accelerate beyond 60 only if the road is level. Any grade and 55 is about tops. There is no turbo whine at any speed.

Essentially, I can drive the car fairly normally on city streets. Freeways are a challenge.
