Blikajuca kontrolka zhavenia pred startom

[dodes19]

Ahojte,
pred startovanim (vzdy len rano ked je auto uplne vychladnute) mi blika kontrolka zhavenia. Po nastartovani zahlasi chybu motora...ale po minute vsetko zmizne a vsetko je ako keby sa ziadna zavada neobjavila. Ked vypnem motor a znova nastartujem, vsetko uplne OK....cize zasa az na dalsi den rano sa blikanie zhavenia zopakuje, pripadne ked necham auto uplne vychladnut (5h a viac).

Ked som auto napojil prvy krat na diag, naslo tieto chyby:

Ked som ich vymazal a chcel vidiet, ci nejaka zostane pri nastartovanom, tak uz nenaslo nic - proste vsetko uplne OK.
Tak som nechal auto znova cez noc a rano napichol na diag a isiel nastartovat - naslo len tuto jednu chybu:

1 Fault Found
7355 - Exhaust Gas Temperature Sensor; B1 S3

Ja mozem len tipovat (nie som mechanik ani nijaky specialista do motorov) co to je - podla kodu by to malo byt nejake "Čidlo teploty výfukových plynů"
Avsak tie su na aute tri (vraj) pred turbom, pred DPF a za DPF.
Samozrejme neviem, ci to bude len toto - vedel by mi z vas niekto helfnut blizsie identifikovat problem, pripadne napichnut na Vasu diag nech nekupim a nevymenim nejaku blbost ktora bude stat 150-500e a nic mi to nepomoze?
