Hi MB Team
I need help, my AML recently came on. Vehicle Recovery guys ran a diagnostics and confirmed it was NOx Sensor 2 Bank 1 faulty (screenshot attached) and needs replacing.
I am now trying to find the right part number for this sensor, i thought i found the right one (A0009058011) but later realised it is for the Upstream sensor. Whereas i need the Downstream one.
My VIN is WDD2130042A277140
Is there anyone who can share the part numbers for my VIN, both Upstream and Downstream sensors?
Thanks in advance

 

Probably this one (A0009053603) but you should call your MB dealership and confirm with them. They'll tell you 100% what the correct updated part is for your car.

 

Thank you for your reply, i just called MB, they confirmed downstream latest part number is:
A0009058111 this replaced A0009051014 but there are multiple replacements done in the past.
Is someone able run a complete history check of this part, like showing all replacements?
Thanks

 

I would ask again...

 

Call another MB dealership and confirm. @trigital has posted about them giving you the wrong part number possibly. I'd call a few and confirm. You can give them the part number in his screenshot and confirm if that's what you need.

 

@trigital @Billyismyname Thank you both for your help. Looks like the part numbers i shared, both match to @trigital 's screenshot, however Mercedes didnt provide me with the latest part number. Attaching English version of Tigital's screenshot, highlighted in Green is latest which i wasnt aware of. In Red are what Mercedes dealership gave me. This all makes sense now.
Just a follow up question, today i reset the code (without replacing or repairing the sensor), the AML light hasnt come back up, had few short drives too. Does this possibly means; there is carbon build up on the sensor and sometime reading goes off! Mean if i attempt to clear the sensor, this might resolve the issue anyway?

 

I would choose the "remanufactured" one, if you are ready to spend a lot of money.

 

thank you
