Eroare E90

Salut!
Am urmatoarea eroare la un E90 (320i - 2008).
30EA:DeNOx catalyst sulfuric ***
Fault-Set 1 - ( 150336 km)

Engine speed: 736.00 rpm
Exhaust gas temperature downstream catalyst Bank 2: 512.00 °C
speed: 1.00 km/h
stored sulfur mass in the catalyst: 1845.00 mg

In urma acestei erori uneori se simte un miros mai puternic de gaze in masina..

Ma poate ajuta cineva cu o "traducere" a erorii?
