Has anyone had similar problem with their Mercedes?
I drive 2017 e class 220d. I got check engine light on I think it’s to do with adblue. Car isn’t reading adblue measurement. As I put 10L adblue in today and still the sign coming up as “cannot read fluid measurements. However car drives fine itself. Also no message popped up to top up adblue as it use to. Just shows 0 adblue. Is it to do with dpf or any nox sensor? What the problem can be?
I have same MB 2017 with same engine and same problem. I left my car in mercedes and after diagnostic they told me need to replace all adblue tank,it takes a week when it comes from germany to uk and price for fix will be 1850pounds. So seems is not a sensor fauly. No messages on computerHas anyone had similar problem with their Mercedes?

Outrageous sums! £1k for a pump??? I thought aviation parts take the p1ss!Update
Had diagnosed today by Mercedes, cost me £280 just for the diagnosed. they said it took them 3hrs to find the problem. The problem with my adblue is that it needs new adblue delivery pump. Mercedes will charge £1900 to replace the part. They said part itself is for £1000 and labour £900.
my friend had similar problem with adblue but his been fixed with software update.
I will never recommend anyone to buy this piece of ****. I paid 25k nd just over a year how can adblue pump fail? I only did 20k on clock overall it’s done 44k. It feels like you end up spending same amount of money over the years on these luxury cars. If you’re paying 25k for a car, u hope it’ll last for few years before any problems starts to happen but that’s not the case.
The Mechanic was methodical, not only relying on Mercedes Software but also carrying out Manual Checks ... With the latter being vital discovering the Blockage ... Also old fashioned Clean not Replace on the affected part.
Overall 2 hrs of work and the cost less than €100.
Thank you so much for this information. I think I’m having the same problem. Are you able to advise where this pump is located and if it’s something you can access and clean yourself or whether it is something a mechanic needs to do for you?Photos incl urea injection pump blocked and then cleared out...quite a hardened lump was cleaned out
Its in the ad blue tank, in the bottom of it. Needs the tank to be empty before you remove itThank you so much for this information. I think I’m having the same problem.

Hi don't know if technically this part is the pump...it's more the receptor of the fluid just before it enters the exhaust...it's 'welded' to the exhaust...it's @ midway down the car...if you can jack it up safely/ securely you might be able to do yourself ...either way a mechanic could put it up on a lift, undo a few bolts, and clean out if blocked...just show him the photos of the blocked receptor and that's it's located midway down the exhaust...hopefully this is your issue and you'll save a lot of time and definitely a lot of moneyThank you so much for this information.

I see in my original post I referenced it incorrectly as pump...as other contributor states ...pump is more than likely in the tank itself..this is the area where adblue physically injected into exhaustHi don't know if technically this part is the pump...it's more the receptor of the fluid just before it enters the exhaust...it's 'welded' to the exhaust...it's @ midway down the car...if you can jack it up safely/ securely you might be able to do yourself ...either way a mechanic could put it up on a lift, undo a few bolts, and clean out if blocked...just show him the photos of the blocked receptor and that's it's located midway down the exhaust...hopefully this is your issue and you'll save a lot of time and definitely a lot of money
There was no requirements to empty any fluid ...just 'open' this 'receptor' where it joins/enters/injects adblue to exhaust and clean out ... reassemble and thats itI see in my original post I referenced it incorrectly as pump...as other contributor states ...pump is more than likely in the tank itself..this is the area where adblue physically injected into exhaust
Really appreciate your help. I’ll take to my mechanic as not confident of doing it myself. I’ll show him this thread and hopefully that is my issue. I’ll keep you informed on how I get on and thanks once again.There was no requirements to empty any fluid ...just 'open' this 'receptor' where it joins/enters/injects adblue to exhaust and clean out ... reassemble and thats it
Hopefully that's your issue ...also I've not had a problem since ...over 5/6 months nowReally appreciate your help. I’ll take to my mechanic as not confident of doing it myself. I’ll show him this thread and hopefully that is my issue. I’ll keep you informed on how I get on and thanks once again.
That’s great news! Fingers crossed that’s my issue too. Did the warning light go off straight away and the adblue level reading start working or did it need resetting?Hopefully that's your issue ...also I've not had a problem since ...over 5/6 months now
Everything went back to normal BUT bear in mind the mechanic had Mercedes software so perhaps you need that countdown to shut off resetThat’s great news! Fingers crossed that’s my issue too. Did the warning light go off straight away and the adblue level reading start working or did it need resetting?
