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?

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.
