AUDI KLUB

Zdravím,

Potrebujem poradiť. Mám A4 B6 2.5tdi BAU a auto mi začalo haprovať. Ide do výkonu a z ničoho nič začne strácať výkon. Potom znovu nabehne a takto sa to opakuje. Diagnostika vyhadzovala problém s váhou vzduchu, takisto s recirkuláciou výfukových plynov. Váhu som vymenil za novú, takisto nový EGR^* ventil a vyčistené potrubie (parohy). Auto však stále vykazuje chybu P0102 čo je váha vzduchu a 00575 čo je nedosiahnutý tlak v sacom potrubí. Hadičky vyzerajú byť zapojené všetky, ani sa nezdá, že by niektorá bola seknutá, prasknutá a pod. Podozrieval som ventil N75 a podtlakovú reguláciu turba, ale čo som pozeral, tak tiahlo na tej banke ide. Dal som aj nový vzduchový filter kvôli tej váhe a nič. Chyba sa stále opakuje. Skúsil som to dať aj na VCDS a log ale neviem s tým robiť, niečo sa mi podarilo však nahrať.

Ak by sa niekto kto sa tomu rozumie pozrel, bol by som vďačný. Pripadá mi to, ako keby Turbo^* prestalo ťahať - tlačiť, ale neviem čo to spôsobuje.

Ďakujem všetkým a snáď sa táto skupina ešte dlho udrží.

Tu je ten log:
