usuwanie nagaru SAI 3.0 tfsi

[ad4m]

Może ktoś z was poddawał swoje auto kompleksowej procedurze usuwania nagaru?

U mnie pojawił się ostatnio błąd P0491 i P0492. Póki co po skasowaniu nie wrócił.

Chodzi mi nie tylko o usuwanie nagaru z zaworów ale o coś takiego (w pierwszym filmie widok z endoskopu):

Może by tak kolega raczył się najpierw zapoznać z regulaminem i przywitać?

Jasne, umknął mi gdzieś temat powitalny.

Cześć Wszystkim.

Odnoszę wrażenie, że silnik 3.0 tfsi jest niestety mało popularny u nas w kraju.
Bardzo ciężko o szczegółowe informacje.

W USA/Kanadzie problem z gromadzeniem się nagaru w SAI (Secondary Air Injection) jest znany i wielu przypadkach rozwiązywany przez dealerów Audi w ramach gwarancji lub (tego nie jestem pewien) akcji serwisowej.

Carbon clean and the SAI port clean are two different things. The tool is a special pressure washer and atrachements to clean the SAI ports. There is an extended warranty on it for 10 years or 120k miles I believe for most 3.0T out there. I believe it’s about a 9 hour book time job. The front end has to be put into service position and a lot of the front components come off. Part replacement is minimal, a few gaskets and freeze plugs and coolant. It’s more labor intensive.

Znalazłem dokument w pdf, który potwierdza obowiązywanie akcji serwisowej w powyższym zakresie. Tyle, że to deklaracja Audi of America
