It's fine if the compressor is close to the walls (if it's within spec), That's part design.
But, it should never touch the walls, but have enough room to expand when hot.

But if there is a lot of play in the shaft, that's a sign of a turbo on its way out.
That might contribute to your underboost problem.

But can't really specify better, without some decent logs with me7logger.

For the last time, get proper logs.

Obey the forum rules.

I have written that I will be able to write down the correct Log only after I will replace turbines!

Today I have read mistakes and I have received
17965 — pressure Regulator наддува:выход from regulation range (it is more than the top limit)
16490 — Pressure on an air intake/pressure => (G71/) F96 a doubtful signal
16621 — the pressurization pressure Sensor too low level of a signal
17956 — the Electromagnetic valve of restriction of pressure of pressurization-N75 break of a chain

Sound like either you MAP and N75 are trash,
or your engine loom has problems?

Yes, it seems to me too that problems with tubes of turbines (I think that tubes where that have come off)
On the street to look it hasn't turned out, we have cold-37 degrees, will go to a garage tomorrow if it turns out I will write down Log
