I just saw this post. That code is telling you that the comanded boost pressure wasnt reached.

The newer 2.0tfsi cars I think have the same issues as the older 2.0t cars where the deverter can go bad. But I also think the newer cars have weaker turbos. Im not an expert on the newer cars so dont quote me on that.

Still from the code the control seems to be an issue. As a bright side this can be more of an issue on super hot days as the air is very thin and it can cause regulation issues. If you can clear the code and get it to come back on in a few days that would lock up that there is deffinitly an issue.

I don’t know if you got my PM Saki but the B8 2.0 TFSI turbos fail more commonly than the older B7 2.0T FSI turbos.

The B8 2.0 TFSI engines came from the factory with the most up to date revision piston style diverter valve that Audi released for the B7 engines. The part number should be 06H145710D.
