VW Touareg Nox sensor fault P22A7 U10C2 - nox sensor 2 replacement

[@youtubeleavemealone]

This is a great video. Thank you for posting. I have the same issue on a 2014 Touareg exec. My pipes and wire routing are a little different, but the sensor is the same. I have a particulate sensor where you have the Nox sensor. My Nox sensor is on the other side of the pipe. My pipes have band clamps rather than flanges. My wire routing goes behind a heat shield that needs to be removed to gain access to the wire connection. The DPF, DEF injector, Diff pressure sensor & most of the rest look basically the same. The connection for the particle sensor is out in the open like your Nox sensor is, but that is just a 4 wire sensor, not a 5-wire, so between that & the diagram in the manual, I feel pretty confident about my sensor IDs. Thank you for a very good overview. You saved me a lot of reading.

Brilliant video, thank you. I've got the same car and warning light came on yesterday. I've got a Carista OBD reader and it came up with code P22A7. I've managed to reset it and the warning light has gone out, so I will see how it goes. Thanks again 👍

I've got the Carista too. Identical fault. Reset code after about 2 days fault comes back. Reset again,fault returned again.

We had this. Cheaper and easier fix is to just get ad blue mapped out for £175. Never have any of these issues ever again.

Is P20EE the same thing...I have 2013 touareg tdi

[@TM22549]

@@daisyhenry332 yes, the whole AdBlue system is a complete disaster. We had 2 NOX sensor replaced under warranty but the final straw was “ad blue tank heater element failure”. New ad blue tank required £450+ all the labour. Bloke came to the house, plugged in laptop and eliminated the whole AdBlue system for good.
