Heater of Nox sensor error C220 W2015 Bluetec
Hello guys,
I'm writing because I have an issue, perhaps here I will find somebody with same problem.
I own a Mercedes C Class W205 Bluetec car, one day suddenly apeared the check engine. I drove to the carservice to check it.
I got the following error codes:
P220E77 - Heater of Nox sensor 1 (cylinder blank 1) has a malfunction. The commanded position cannot be reached.
P220F77 - Heater of Nox sensor 2 (cylinder blank 1) has an electrical fault. The commanded position cannot be reached.
P228007 - air mass flow in the intake air system blank 1 has a malfunction.
The weird thing is if I delete these errors, the check engine disapear, I can drive a lot, sometimes more than 100 km, after that check engine apear again. If I delete again, i can drive also without any problem. Unfortunately there isn't any logic, sometimes I drive a whole week without any error, sometimes few days only.
Somebody has similar issue ? What should I do ?
There is two sensor if I had to change all of them, that will be expensive.
Thank you in advance,
