C250

[simonhoskisson]

March of this year I purchase a C250 on a 15 plate. Not long after purchasing it the engine management light came on, 12/24 hours later the ADD BLUE came on giving the countdown of 500 miles or the engine won't start.

Anyway today it came on again, for the fourth time, it's been into Mercedes 4 times and each time they say they have rectified it .

Just over 8 months and this as I say will be the fourth time they will have had it for the same faultfail

Any advice would be greatly appreciatted

I take it the car hasn't actually run out of AdBlue?

No they have filled it up each time, even had a roadside Mercedes engineer and he filled it up whilst I was with him, could get the adblue to say it was full.

I also have a C250 Bluetec and have the same problem. Car went in for a service with EML on. Garage say NOX sensors have failed so will be replaced soon when in stock. During service the Adblue was replaced.
A few days after that the AdBlue warning countdown appeared so I took it back to be checked. After a software update the AdBlue warning was deleted.
A few days later it reappeared but my garage is closed for a holiday so have to wait.
What was the outcome with yours?
