Immediately after the verification that this is really sensor 2

What are the first six digits of your Vehicle Identification Number (VIN)?
In the absence of such, there exist several distinct models to verify the Part number.

The number is 182,202. Apologies, I assumed that one would be designated for before and the other for after. Thank you for your assistance. Mercedes-Benz GLC 250dv

I doubt that the numbers correspond to the first six digits of your Vehicle Identification Number (VIN).
The desired format should like (WDD) 253***.
A 253 refers to a GLC, with the next three digits specifying the precise model.
There are four distinct GLC250D models.
Retrieve the numerical values from either the bottom passenger side windscreen tab or the V5 ownership paperwork.

I have examined all four models of a GLC 250d and found that the Nox sensor is located after the catalytic converter. The specific part number I possess is A000 905 98 03, and its current price is £362. However, it is important to note that this pricing information may have changed since the publication of the catalogue.

For your information Observe Part 400 in the figure below to locate its post cat.
The sensors positioned above the Cat are the Lambda sensor and two temperature sensors. The graphic displays part numbers 220, 235, and 240.

Apologies, I was in a hurry and mistakenly assumed you mentioned the previous six. It was only a reflexive response. "WDC253".

There are two nitrogen oxide (NOx) sensors available. I am looking for sensor 2, which I think is labelled as 490 on the figure.

Both of them seem to be post cat. I am perplexed. Regardless, I am seeking sensor 2, whatever one it may be.

Is this the one that I believed was sensor 2, and do the cables have a short circuit similar to the 490 in the diagram? a0009050008, I just want to avoid ordering the incorrect item. It may be somewhat perplexing, to say the least.
