Hello,
Recently i unlocked a new emoji on my car - check engine. It appeared when i accidentally started to move on 2nd gear (actually it was one of those moments, not really 1st gear, not enough for 2nd gear). I said "huh.. well it should go away if i stop the engine maybe" and of course it didn't cause.
I connected my car to diagbox, observed this P2047 error, cleared it and it then everything was ok. The next day sadly the emoji returned after a few km in the city (and no, i didnt start on 2nd gear again, I was driving actually pretty fast to "clean" the engine, low gears pretty high RPMs).
I searched the internet for this code but no concrete info, a lot of causes and stories but no concrete investigation and fix. And ofc, the classic "new adblue tank eur2000" which i call bullshit and sounds like showroom does not want to assume the problem.
Any idea what could be the problem? Are you familiar with this?
Thanks in advance!
Edit:
Seems like NOx sensor has some crazy values for gas flow. As i don't have any other lamps on in the cluster beside check engine, probably a bad sensor/dirty one might be the problem (?).
I have the following information from diagbox:
Engine stopped:
