You just answered my previous question, almost undoubtably so depending on how you drive it. More power requires more fuel, more exhaust gases, higher turbocharger RPM.
Less reliability, keep on top of the oil changes.
Turbo not right

Done smoke tests mate nothing at all. It was a brand new original garret vw turbo mate identical to the original same part no the lot.
Correct - per workshop manual there is nothing to adjust.
Is it the IDE00457-Test of turbocharger you are using to generate the whining (at standstill) on video?
Did you log any data during the test to share? E.g. as below
Please post engine blockmaps
1) ignition on, engine off
2) engine idling
How-to create a blockmap file:
[VCDS]
[Applications]
[Controller Channel Map]
- Single Controller Address = 01
- Login or security access code: Leave blank
- Function: Measuring values
- Output: CSV file
[Go]
The result (CSV) files are saved into directory C:\Ross-Tech\VCDS\Logs
I did use that but never captured data will do so today mateCorrect - per workshop manual there is nothing to adjust.

TURBO TEST: hopefully this worked VCDS glitched no end throughout ill do the block maps now
idle
ENGINE OFF IGN ON:
Tried again just incase the first didnt work
Seems to be quite an old file - dated 9, July, 2025
So this thread is a continuation of the New turbo calibration and New turbo calibration
The turbo adjustment seems to be still well within spec. Also no excessive pressure generated during the test.
Now the turbo generates normal pressure during the test as opposed in test last year
Don't think so as at the test the turbo is anyways squeezed to the max (what's achievable at those revs and without load).
Of course you could choke exhaust to see if increasing backpressure (a kind of emulating DPF) would make any difference.
I’ll give that a go this morning. I may have uploaded the wrong file as the logs from last year will be on my computer still is the data I sent all you need? I’m guessing if I block the exhaust and the sound goes then it’s just the new sound of the van without DPF? I’m going to book an MOT this week then if we are all functioning as we should be.
