W213 - HELP!!! Adblue - Cannot Measure Fluid Level

Hi All,

My E220 2017 now has engine management light on but fortunately I can see the reason why. The adblue level is not measurable on the indicator on the digital display. I know the adblue tank is 75% full. It started flashing the level indicator on and off with 6,500 miles on it but now is just permanently off with the message “Cannot Measure Fluid Level”. Fortunately it hasn’t put me on a countdown timer to when the engine will shut off. Any ideas would be greatly appreciated.

The level sensor gone at the AdBlue tank, seems to be a common issue.

You can reckon with about 1litre per 1000km AdBlu consumption, assuming you have a saloon/estate then there they have a 24 litre tank. The most i have tanked was 21 litres with 450km left so you likely about 18 litres or 18000km. Cab/Convertible have a 13 litre tank.

Repaired twice

I have had the same problem fixed twice both time the adblue tank needed replacing, the sensor that goes faulty cannot be replaced instead the whole tank needs replacing, costs around £1750 each time

Fortunately mine was under warranty so didn’t cost anything, however it was the NOX sensor that needed replacement. A few hundred quid minimum.

I had the same issue a week ago, it turn out to be a blown fuse, after replacing the fuse I had to drive the car for about 20-30 miles and it worked again.
Hope this helps.
