Adblue delete

Why? If the car is being serviced by a dealer every year, then you would trust them "to do what's necessary" - why would you assume that they did not top-up the AdBlue?

Obviously, if you service your car DIY, then this is a different matter.
Both DIY or garage servicing will generate an invoice/receipt for the purchase of the AdBlue. The absence of said receipt is a good reason to walk away from any car thus being presented for sale.
 
Not putting adblue in for 3 years or 20,30k miles would raise my suspicion.
I've spoken to a woman who did not know her Jaguar used Adblue until she got the 500 mile countdown. She took it to the garage she bought it from, who put more in, the countdown disappeared and she went on her way thinking this was normal. I don't think she learned anything from it either.
 
There's also a guage that always reed's full with a ridiculous range 🤔
You lose all range and digital screens when ad blue is deleted . The first thing anyone buying any used diesel car , should check ...

Ok. Ive had my C250d for nearly 9 months, been France and back, lots of running around and still showing full? So i don't know.

I've said on here earlier, my C250d used very little Adblue, it would stay full seemingly for ever as it used so little. Since it developed the Adblue countdown and was "fixed" for good, it doesn't use any adblue at all!
Funny how so many folk are aghast at getting rid of a system that only used a thimble full of Adblue every week, all these "green" afficiandos are killing everything they can in the name of saving the planet, but it's all pretty much meaningless in the grand scheme of things.

You can also find the ad blue controller module and check if it's been disconnected. If your still seeing range though ,chances are it's using ad blue . I've owned my glc 350 now since August it's still showing 7700 miles , it does tend to drop as the mileage on the car increases, I check maybe every 400 miles or so. A quick check with something like icarsoft will also show voltage to tank ,tank temperature,fluid levels . If it was disabled,you'd see none of those things.
 
Just saw this:


The mystery here is that the AdBlue controller was removed by a previous owner (probably because it failed), even though replacing it isn't actually that expensive? Especially if you own a newish S-Class ..

Just to add that I had 2 services done by MB main dealer (with adblue top ups included) and they didn't notice the adblue delete...Only came to light when they carried out the diesel software update.

"AdBlue top up included"... ? I can understand the first time, but the second?

BTW, did you buy the car from an MB dealer originally?

Maybe the adblue level dropped because it crystallised ?

Then it wouldn't have worked right away once the controller was reinstated.....

I had a service plan in place (3 services, just had final one done last month). Car was bought from Praters (not an MB dealer)

I meant maybe thats the reason they topped it up again on the second time . (Level drop because of crystallisation)
I thought that’s what your original post had been getting at ?
 
System has been working perfectly since. I added Forte adblue crystal preventer. The injectors connected to the exhaust have been removed and checked - zero crystals present
I had meant level drop in the adblue tank ? As to why MB topped up an adblue deleted tank for the second time without noticing.
 
I believe that "top-up" to MB means "check the level and add the required amount", so if the level is OK, zero addition = "top up" carried out. ;)

They ticked my box saying ad blue full. I wouldn't be bothered anyways as it's not free on a service.
