Ad Blue Sensor

[Paula Gormley]

Hi All

Just got my E220 2015 Mercedes serviced and now the ad blue sensors seem to have gone. I am getting a warning message that the engine won't start in 700KM - has anyone had any experience of this in a 2015 as to replace the sensors are extremely expensive!!!!

Welcome - one or two owners of MB EU6 diesel cars seem to be posting this fault recently the only thing you can do is make sure the Adblue tank is full and if so a visit to the dealers is the only option for a reset and diagnostics on STAR

If you post your location , a good MB independent may well be cheaper

I had my 220d (2017) serviced a couple of weeks ago before the service the display told me I had a 9000 mile range. During the service the Add Blue was topped up with 12 litres but I now only have a 7000 mile range???
Anybody else has this problem?

Not this specific problem, but the predicted range seems to bear no relation to reality. Mine has done just over 9k miles and is showing half full with 2200 miles remaining. This sort of disparity has been present throughout.

I’ve read that this fault maybe due to a faulty Oxygen Sensor. At this rate it’s using a litre for 260 miles.
