I have 2016 Audi A7 3.0T with CREC engine. When I look at Charge air pressure specified value via ODIS, the value is always stay around 1bar. I think this is kind of weird, does anyone have this problem?
Boost pressure issue?

Are you accounting for the actual atmospheric pressure around you, then when driving this will rise of course with the forced induction.
Question is, are you seeing any issues with the car when driving, of not then I'd say it's more diagnostics that aren't working as they should, if the cars boost is missing then that would.be why it's not logging as you'd expect.
I got EPC light on when I drive with full throttle, and got code P0235. I've reviewed some materials that shows the p0235 is raised if Boost pressure sensor signal vs target value > 27 - 50 kPa, depending on altitude. And I see the actual pressure is 1.7bar when full throttle and the specified value is still 1bar, the difference is 0.7 bar which exceeded the threshold (27 - 50 kPa or 0.27 bar - 0.5 bar). This is my logical inference, but I don't know how to solve it. I also tried to replace the boost pressure sensor, but the problem persists.
Yes, I got stage 1 tune a week ago, and then the EPC light came on during full throttle. Afterwards, I had the tuner restore to the stock program. Although the situation has improved, the light still comes on. I'm not sure if the pressure specified values were normal before the tunning, but it seems they are not normal for now.
Maybe you should of told us that initially.
Take it back as he hasn't restored it to factory I'd say as the issue is still there, assuming it wasn't there before the tuner played with your ECU.as you had no cluster light, so I'd say it was working fine before.

Should do yes, it would probably have now left a flag on the ECU to say it's been flashed, now unless Audi have stopped Odis from ECU flashing if that flag is current, only 1 way to know.
