AdBlue Bypass

Question by donwoodlynnefarmcom posted 7 months 4 weeks ago in 2007-2012 (X164)

I am having continuing problems with the adblue system in my 2012 GL350. After filling with MD AdBlu the start limit notice doesn't reset and after having it reset my the mechanic it comes back on within one or two starts. Is there a bypass available for the system or a way that I can reset myself? Software was updated by local dealer but problem persists. I heard there is a Mercedes fix that reprograms the sensor to accommodate the resistance degradation of the sensor. Is that true?
