YTMercedes  W470/471 Engine light
After filling up with adblue at my local dealership.
malfunction light came on.
they reset it Cannot get booked in for a few weeks

now I have a engine light.
Xentry scan reveals N3/28
P30055F Malfunction

I'm trying to ignore event and erase P300964.  P300965.
If any one can point me in the right direction.

think nox sensor went faulty?

driving me mad watching engine light return due to the above stored faults
thanks in anticipation
