Im a new member. I recently bought a W205 c220 BlueTec. I just have a question about the adblue for these vehicles. I see on the display of the car the level shows empty, but the distance shows 10000km.
I assume this is not normal?
Is it possible that the previous owner somehow bypassed the system?
If so, how can I check?
Thanks for any insights.

Perform a scan of the vehicle and see if you have communication with the SCR/Adblue control module. When the systems has been deleted most of the time it has been unplugged.

Hopefully some good news. We never let our AdBlue drop below 50%. Top up with quality AdBlue that is recently made and stored in a cool place. 50Km into a 125km trip the error message activated, 15 min later the display said 800km range till engine shuts down. Got to destination, stayed there 5 hours and commenced return journey. Still no level detected and 800km range reducing by 120km when we returned. Got quotes for new tank - $3400, 4 month back order from Germany, no stock. AdBlue delivery pump - $$1800, in stock. Nox sensors x 2 _ $1650 each.
Risk the tank, pump or sensors has been disabled due to crystallisation in tank.
Research let to some manuf, all overseas who sold a AdBlue additive - used in AdBlue tank. Selected brand “Forte” and preferred option, 125ml services 20l tank Benz tank is 27l.
Car rested for 4 days, battery charger connected to top up battery in case electrical knock on ??
Ordered “Forte” Exhaust Crystal Preventer from UK, DHL Express delivery, arrived in Oz6 days later.
1 x bottle dispensed, sat for 3 hours. On starting engine alert still on dash. AdBlue tank now seeing virtually full tank - 700km range gone, no messages on screen except for engine light - I suspect it will go when error codes cleared.
Drove GLC at 100kph for 30 min ,rested car 2 hours and returned @ 100kph for 30 min. No more issues !!!
Hopefully this id the golden arrow that fixes the issue. Forte recommend 1 x bottle every AdBlue fill - won me.
Hope this helps.
