NOX sensor stats

[JustmeJB]

I'm in the middle of the NOX sensor issue having just had one replaced costing £700 and now the EML has reappeared so fully expecting it to be the other one despite these being replaced within the last 18 months.

Google NOX sensor issues and the big majority of results relate to Mercedes cars.

So it got me thinking has anyone requested stats from Mercedes as to how many NOX sensors are changed in the UK every year. I wonder if there's a case for these cars being deemed not fit for purpose. I was chatting to my local main dealer today and mentioned a suggestion of hard driving to keep the sensors clean but that contradicts the intention of the ad blue system and also if the car needs two each year costing 1400 then surely that's not right. No surprise he didn't respond verbally but his expression said I hit a nerve.

So just curious if anything like this has been done already and if not then would it be worth it?

I don’t know much about class action however, I found the post interesting here, where a fellow forum member states in Post No.6 that resetting can sometimes deactivate the code for a year: Nox sensor seized | Parts, Maintenance & Servicing

Funnily enough I was just reading that myself. I'm now trying to figure out what £25 OBD tool the person is on about as it almost sounds too good to be true but definitely worth a go.
