Ad blue in cars

[chickens and wheat]

the adblu sensor is normally ultrasonic, this can decent to urea concentration, also the fill level.
Over fill and the ultrasonic sensor is submerged and cannot get a bounce back signal, so it will decide the adblu is not upt o quality., normally telling you it will only run for x miles before engine restart is not allowed.
often the tank level will drop below the sensor before x miles is reached

basically never fill the tank right up, especially if it has a long necked filler

On top of which, an ex VW tech told me that the VW system was not well thought out, in fact it was a whole heap of sh!t rushed out after the diesel software scandal.

I think most of the first eu6 engines had the same problem. Rushed into development.
As you say when manufacturers realised they couldnt cheat they suddenly had to make things work much better than they thought.

I baiIed out and changed to a petrol car last year, but then stepped back in again with a ford ranger this summer.

We have 6 customs at work and all are sh!t on ad blue range. I believe they have a 20L tank (based on how much it takes to fill) only get 5-6k out of a tank. That's doing ~3k motorway miles a month.

That's the sort of range mine gets, I found it cheaper to use the new add blue pumps that are popping up at garages now.

Peugeot partner van ( 2016) only uses about 1 litre per 1000 miles....much easier filling with a smaller drum than a 20litre one

Not true. We are using a 4 year old ibc of adblue which was left over from a hired tractor. We’ve no other adblue things apart from 4 cars which have been using this ibc the last 2 years without any issue.

As Techs, we were told by the manufacturer to just use 6 months as a good rule of thumb. I've personally tested DEF after it came out of a guys drum that was roughly 7 months old and it was below spec. If your not personally having any issues, then I would say that you've either found some of the best maintaining DEF there is or your vehicles don't particularly have that sensitive of systems on them. I guess vehicles here in the US are overly sensitive sense just about anything will tick them off

We did fill up a discovery sport from the farm tank and it threw a warning about Adblue quality.
Ended up draining it and buying genuine Land Rover Adblue - another con.

All the brand new tractors and wagons are perfectly fine with Adblue from the same tank.

I had this, I rang LR and within an hour a man came out and did a software update FOC the sensor is too sensitive rough ground & low adblue can trigger it too.

Just don't overfill it, can cause some grief if you do. It can appear to the computer that you have not put any in at all, and then it will give you the message " your car will not start in 250 miles" then 200 and so on and then it's trip to the dealers because none of the independant garages know what to do or can't get the software to sort it out.

I bought a small proper bottle which shuts off when there's enough in the tank, then refill that over and over

Jeez, I thought that I had problems with printer ink cartridges!

What brand of def? I might have to start using it if it's holding up that good, but honesty I could probably buy a big drum and not have any problems anyway as I rack up 4000miles a month. That's 5 gallons a month, so would need to last 10 months. Yours is going on 4yrs, so should be good with your brand.

Do any of your vehicles regen a lot?
