2.0 CDTi and P0234-11

That link is not there anymore,
But as long as it's moving then you can rule out VNT sticking .
Check the vacuum hoses just to meek sure there's no splits .

Made 2 test today and got some live data. SVS happened near the end of both recordings. One is boost log other is engine data. Can you please take a look?

1 Boost data - https://docs.google.com/spreadsheets...it?usp=sharing
2 Engine (for MAP sensor) data - https://docs.google.com/spreadsheets...it?usp=sharing

From what I can see seems like boost pressure sensor
Because to me there is a lot of difference at one point between the Kpa values of desired and actual.

Just to be sure - the MAP sensor (inlet manifold)?

The vane position sensor looks quite strange to me at times compared to the desires vane position. Sadly I cannot understand what does it mean exactly but can it be related to faulty MAP as well?

Did you replace the map in the end ?
Signal from the map then goes to boost pressure sensor which has a hose that connects to the VNT solenoid and thus opens and closes the VNT .
The only thing you could try to get hold of is a small pressure pump and connect to that hose that goes to the VNT and apply pressure to see if the VNT arm moves under pressure .
The vane position solenoid valve command , and desired vane position and valve open or close % do go a bit odd now looking at the figures further down , did not realise I could scroll down .

Hi, the issue last year was resolved by replacing the BCV. Sadly, I just had the same SVS problem and just did a check - P0234-11 again. I suspect that one of my cooler pipes is damaged as it was damaged two weeks ago (small split near the end of if) which I fixed just by cutting off the damaged piece. Also the car seems to be a bit lower on power and a lots of black some come out after hard pedal kick. Will have to check it again. Oh boy, I my biggest fear is that P0234...
