Can you undelete AdBlue?

E-Class 250 CDi Sport Estate Tip
My 2017 E-220 currently has a non-AdBlue related issue which is covered under the extended warranty I took out with the lease company. However, the car has to go in to be fixed, but last year I had a separate AdBlue sensor failed issue, wouldn’t recognise any level change when topped up, giving the dreaded countdown.

This would have been fine had it not happened two days before our annual family holiday abroad in that car, and our only car at the time. I looked into it and saw it was time consuming to fix conventionally (possibly weeks), so temporarily ruled this solution out. But to avoid a potential holiday cancellation (and guaranteed domestic nuclear meltdown), I searched for a solution and found a guy who could "deactivate the sensor", allowing the car to run as normal for the holiday, and "which could be reactivated" when I got back, and then I'd get it fixed under warranty. The car ran fine, exactly as said, so I called him when we returned but the number was deactivated (go figure). I intended to then find someone else to sort this, but life went on and as the car ran fine, and work was chaotic, I forgot about the issue and it got put on the back burner. Yep, my bad.

As the car now needs to go in for other warranty work, I'd like to get the AdBlue sensor issue sorted at the same time also under warranty. But as the dash states "Cannot measure fluid level" I'm assuming this is a red-flag that the garage will check/spot? Or is there another standard Merc fault which also flags-up this same dash warning? i.e. this warning doesn't solely show up when the AdBlue software has been deleted.

If there isn't another standard fault which generates this message, I guess my only alternative is to find someone who can undelete, or possibly reinstall the OE AdBlue software, if this is even possible?

I'd simply like the car to go in with 'normal' looking faults and there not be any red flags, and the issues be fixed under warranty.

Any help or experience on this would be much appreciated.
 
If the car is subject to a lease then you do not own it so shouldn't have it modified without agreement of the leaseing company.

As to the person that deleted the Adblue no longer being available, perhaps he suddenly realised that what he was doing was illegal?

A change in the software will be noticeable if the garage looks.

He was technically doing nothing illegal as long as he made the owner aware (but clearly the owner new the rules).....only the driver taking the car with a modified emissions system on the road afterwards was.

From .gov website..
"Under the Road Traffic Act 1988 (Section 75) it is an offence to alter a vehicle in such a way that the use of the vehicle on a road would be unlawful. A person altering the vehicle (if they knew or believed that the vehicle would be used on the road) could be found guilty of an offence under the Act.

Potential penalties are unlimited fines."

 
Ok.....so how come only the users ever get prosecuted (very rarely TBH) and yet the centres offering these services and openly advertising them never seem too. There are sponsors/advertisers on here advertising/advocating those very services. I'm guessing they use the old "not for highway use" get out clause....and then watch them drive off down the street!! 😄

Something not right here. If you've had a proper adblue delete, you do not get warnings like "cannot measure fluid level" or any other adblue warnings or lights any more.
Not sure whoever worked on your car knew what they were doing to be honest.

Probably a grey point in law.
 
The clown next door to me has had the DPF gutted adblue delete done. Laughed at me when I told him that my Ducato had just had a £5k DPF/adblue injector fitted. He is now having kittens because he has adblue low warning and engine will not restart after 300 miles message on the dash.

He hasn't had an adblue delete done then, despite what he's been told.

You need to see an independent MB specialist with STAR who can figure-out what has been done to the car previously, then reinstate AdBlue as it was before, so that you can take to another garage to be inspected under the warranty that you have....

(And pray that the warranty covers AdBlue faults.... and that the cost of the repair is not higher than the warranty claim limit, if there is one)

If the issue had been 'sorted' correctly and "cannot measure fluid level" wasn't showing, what would show when you checked the AdBlue level on the dash?

This is where they differ depending on who has overwritten the files. Its possible to still have the adblue tank level showing maybe half full, but the remaining miles till empty will be blank.

I guess either way, it looks like something has been done to the AdBlue software? And will flag up on their systems?

If this had been done correctly, would it then have been possible to reverse the procedure?
 
Thanks, what's STAR? Are their systems linked to the MB main dealer network?
Star is the official MB diagnostic system which, for some coding, connects to the main MB system in Germany and probably would for warranty claims.

So, to summarise, you have illegally modified someone else's car and the "expert" that did this has now disappeared and your warranty may be void?
 
It's a 7 year old car ... it was presumably leased at some point, but surely isn't now? :dk:
