Adblue not updating

[ShazzatheChef]

I may have overfilled my Adblue tank. It won't reset to new level. Thinks it only has 600miles left when I've put 10 lites in the tank. The van's been plugged in by a local VW specialist and they've cleared the error but it still hasn't registered the extra Adblue. Any advice please?

Keep driving, it will reset maybe after it’s next regen,

How do you make it regen. Is there a way to force it please? I though regen was something to do with burning carbon off the diesel filter.

It will regen when the filter reaches a certain level, I wouldn’t try and force one, the van just needs to use up some of the adblue so the sensor can read the level. Others have drained some out of the tank when overfilling but not something I would consider until it thinks you only have a couple of hundred miles left

What was the level before you put the last 10 litres in?

Were there any other error codes?

 

[ShazzatheChef]

It was showing @1000 miles then I put 10 litres in the tank. I don't know about error codes. I have a Carista unit but not used it yet.

Which van? My 6.1 took 20l after the 1000 mile warning.

Update - all working fine now. Updated to 5000 miles.
That's all I did was to fill up on diesel. Apparently, the regen doesn't happen if the tank has less that 25% diesel left. It updated as soon as I switched the engine off after the diesel was added. Happy days and panic over!! Thanks everyone.

I have the same problem. It showed 1000 mile warning and I added 10l of adblue. I driven 500 miles, filled up with diesel and it now gives me a 500 mile warning with the extra message that the engine will not start after 500 miles. Can anyone help me?

Welcome to the forum @Ael-y-bryn

What generation of van do you have?

 

[Ael-y-bryn]

It is January 2021 reg Combo Sport line.

Adblue warning it is fixed; me very happy.
I put another nearly 10 ltrs of Adblue in.
Switched on the ignition and it reset itself with a range of 6,000 miles.
In the past, I have added 10ltrs at the 1,500 warning and it resets to a range of 3,500. Whereas on this occasion I left it until the 1000 mile warning.
The lesson for learning is if you let it go as low as 1000 you need to add more than 10 ltrs say 15 ltrs.

Your van should tell you the advised range to fill up on the MFD? Mine does but mines a 6.1

Beware overfilling, if you fill past the sensor then it will read as empty or nearly empty untill you remove some.

I only recently learned from this forum that you can change the MFD from gal to l.

This little difference makes it easier to understand when you are about to over fill.

Just need to in the below image change is change the Volume to “l”
