Hello @sazam ,
The issue with finding the N272, is that it is called the "Boost Control Valve" in IETIS, as @Dark Green explained above, they are known as the N75 and the N272, just as a designation name/number, although they both are the same as in what we all know as a N75 valve.

Here are the steps to finding the N272 in IETIS.

I also posted my pictures of the 2011 Supersports engine, and my 2014 engine where I removed the turbos from to use on my Supersports engine, you can see that the Supersports engine had the N272 still on the engine, so the dismantler whom removed the turbos from the SS engine, left the N272 in place, you can see on the 2014 engine as I remove the drivers (lhd) side turbo, that the N272 and associated hoses are still hooked up to said turbo, along with the electrical connector with the red and white wires.

There is also a picture that I screenshot from Google (as DG deleted his picture and comments) that was part of this thread, whereas DG showed the N272 from the side with the 90° funnel of the turbo removed to gain access.

as always! thank you so much @1eapplebaum & @Johnny Hotspur GT .

will do the tests / logging as you suggested.

 

Greetings. I have the same error hanging, but physically does not manifest itself. How did you solve this problem?

 

ignored for now - how about you? fixed? fix in progress?

 

Hello. There’s no time yet either, but my master said he’ll try to unscrew the radiators and get to valve N78. The check either pops up or goes out, but has no effect on driving. I have stage1 firmware, maybe because of this.

 

probably possible on the passenger side, but the one on the driver side may be challenging to get there by dropping the front only.

pls inform how you managed all this when your master will do the job, would be great to know if any tricks were needed.
