2016 S212 E220 Nox Sensor failure @ 75k

Its now saying 4500 miles for Ad blue now! Ahhh i give up lol

It can take 3 ignition cycles to register added ad blue or a 20 minutes drive. By the sounds of things I'd be putting 250 MLS of anti crystal in now . £10 or £1000 , your choice.

Put some in but the ad-blue warning comes on now and again where it cant read the level. I just drove 300 mile today

Hopefully it will attack any build up on the level sensor if that's the issue ?? They say to empty ad blue at 2 year intervals and refill with fresh . I put anti crystal in every winter , preventative maintenance is better than the cure when it fails .

Does this have anything to do with my original NOx sensor problem that is being repaired on Thur?

Possibly, if the system couldn't see ad blue ,it's not been spraying any in , which inturn would effect Nox sensor readings , did the Nox sensors flag the eml during your 300 miles today . ??

Thats the faults. The EML has been on since Thursday mate and has never gone off

Shame you've not got a scanner to turn it off . Your faults all seem to be Nox sensor 2 ..

Won't your mate turn it off for you ?
 
He is replacing the sensor on thur mate so will that turn it off?

Id imagine your journey will begin on Thursday at some point you'll find yourself driving up the 1231 to the dealers.
 
Been a long weekend mate! Just drove the car and it’s reading the Ad-Blue level!!! Give up with this car lol

Good news.

Are you planning on keeping the car?
 
Just be aware, the cannot read adblue level warning, is intermitant to start with, but in most cases will get worse until you get the 500 mile countdown.
I'd get that checked along when the sensors are fitted and get back to the warranty company to make it part of the same claim.

So, the sensor that is being replaced on Thursday will not cure this issue?
