P0299 on Audi vehicles The turbocharger or supercharger is not making the boost the computer asked for

A model year is listed because the code is named in its own record — a bulletin filed against it, or an owner’s complaint about it — not because every one of these vehicles sets it. Counts are documents in NHTSA’s files, not failure rates.

Owners’ own words, scrubbed of anything identifying. Unverified reports filed with NHTSA — what was said, not a finding that it was true.

Bulletins and campaigns Audi filed with NHTSA whose summary names P0299. Quote the document number at the service desk — it is a diagnosis the maker has already written down.

A stored code names the test that failed, never the part that caused it. The record above is what Audi and its owners have filed about it; the code’s page across every make has the whole file.
