Urgent advice needed. Re: Petrol engine nox sensor
Discussion
Urgent advice needed.
I have a 2014 W205 2.0 PETROL Turbo. Unfortunately, the EML has come on and it looks like it needs a Nox sensor. As is well documented, there is a supply shortage of sensors and Mercedes would not even commit to a delivery date.
Work have just informed me that I will need to drive up to Glasgow area to survey a job, which would entail a 650 mile round trip. I have explored alternative methods of transport but due to the location and logistics of the job, taking my own car is the best solution.
My question is this: Would driving that distance with a potentially faulty Nox sensor cause any serious issues on my petrol car.
Currently, the car is still performing faultlessly, with no degradation in performance or economy.
Any advice would be greatly appreciated.

Is it definitely a Nox sensor and not an EGO sensor? I thought Nox sensors were mainly used for diesel aftertreatment systems.
I think some very modern petrol stuff might have them....2014 doubtful though.Not sure though.
Not sure if the post that resurrected the thread is spam or not though based on another post they made.
Just to update.
It was indeed a NOX sensor. Modern petrols have them fitted. I managed to get a new on fitted after hunting all over Europe for one. The independent garage I was using could not code it in, so I had to take it to a main Mercedes dealership to have it fully set up.
All was well for a week or so before the light came on again. Once again, the NOX sensor had failed. This time, I could not locate one anywhere and Mercedes would not even specify a delivery date. After speaking to one of the techs at the dealership, he said that the wait for NOX sensors has been up to six months.
After a number of other niggling issues, three further failed attempts to buy the same model again but newer and a better spec (all three had exactly the same issue! It did explain why the last dealer was reluctant to let me plug my code reader in!) and the fact that it was increasingly more difficult for my arthritic wife to get into to the C Class, I decided now is time to part ways with the car and try something else.
I managed to get a reasonable deal on a Skoda Karoq so I am going to give that a go for a while. Believe it or not, the Skoda actually seems better built than the Mercedes! I have come to the conclusion that Modern Mercedes cars are not really worthy of the badge unless you move someway up the model range.
I think I will keep the Skoda for a while and look around for an old Merc, early next year. One without all the technocrap that comes on a modern car.

Mercs after the early 90's aren't quite what they used to be.I think I will keep the Skoda for a while and look around for an old Merc, early next year. One without all the technocrap that comes on a modern car.
They are designed by accountants like most others & have no real build quality level higher than any others.
The Skoda is an excellent car, I had one as a hire car for a week for 4 in Cornwall recently & it was excellent.

Hi, I was wondering, after reading you post; as I have the same issue on my w204. Did you sell it with the engine warning light on, and if so how did it affect your private or dealership sale?

NOX sensors are now available although they're pretty expensive - as you've presumably found out. Nonetheless I think you'll get completely nailed on price if you try to sell the car with EML illuminated. In round numbers I'd be guessing a £500 repair vs £1,000 off your selling price.
