Adblue

Recommended Posts

About 4 weeks ago I brought a Mercedes ml 250, all was well until an orange engine light came on, a few miles later the adblue sign comes on saying to top up. I pull into a garage and buy a can and top up, I drive off and it’s still asking for adblue so I stop again and this time fill the tank right up, still the warning lights are on then a message comes up on the dash saying adblue or the engine will not re start after 400 miles. I take the car to a Mercedes specialist not main dealer, he runs a diagnostic test and tells me the car needs an up date in the system, can he do it, no, he tells me Mercedes want 20 grand for the licence to do this fault that they know about any way but are not doing a re call on it only doing it when you have the car serviced by them. Has any one got an ml Mercedes and have you run into this problem. I have found another independent Mercedes garage that have the licence and hopefully get sorted.

There is no doubt these situations are built into vehicles these days forcing owners to return to the rip off main dealerships.  I know my local village garage has had to lay out a lot of money to update all the computerised stuff.  Hope you get it sorted.

Yes I agree but actually building something in that is going to shut your engine down, I think that is going way to far.

There are forums, just like PW, for every well known vehicle. I recommend finding one that caters for MLs, preferably American because they go into much more detail, and it's a good bet that there will be thread about how to update your own software (or some other fix) to beat this crude extortion racket.

Im on the MB Owners forum they are usually very good with sharing information but I think you cannot start a thread till you have replied to ten.

My Vw van has a sequence to follow . Fill it up then turn ignition on and let it say full or 5/6000 miles left. Then turn it on.

 

you can’t just put it in like fuel
