P2200 & P220e ERROR CODES W205 2015 c200 PETROL

[Ibtasam8]

I recently got the P2200 & P220e codes on obdII scanner on a 2015 C200 (w205) Petrol

What does this relate to and what is the estimated cost to fix this in the U.K?

Googling, this seems to be a NOx sensor reading out of range, and the most likely cause is a faulty NOx sensor.

They are quite pricey at £150-£200 for a second hand original unit, to £250-£300 for a new non-original unit. Not sure how much a new MB unit will cost, but I am guessing ~£400.

But keep in mind that it might actually be a true high NOx reading caused by something else.

Said that, the first thing to try is erase the current fault codes, then drive the car normally and see if the fault codes come back.

Ahh ok, thanks. Had my mot recently and it passed its emission test so I'm assuming it is faulty.

Hi all,

I have the same problem, Nox Sensor 1 Bank 1. Kindly, someone know if this sensor is the number 70 in the attached?

I think that:

number 70 is Nox Sensor 1 Bank 1
number 92 is Nox Sensor 2 Bank 2.

Correct? Thank you in advance.
