AdBlue top-up issue (merge)

[lucky13]

mine popped off really easily so I may have just been really lucky with the technique..i’ll be joining you in a week and let you know how I get on

I’ve been trying everything to pop off the pipe with the green push release buttons and nothing is making it come free. I think you’re right about us being screwed

Did you get this fixed as I’ve got a slight update to my issue with a slightly updated guide on how I fixed it the second time…I’ll post this on my next post

Thanks everyone for advice

ok so an update on how I fixed this, after getting down to 200miles before the engine was disabled

I removed the small adblue undertray, 3 x 8mm bolts directly underneath the van inline with the adblue top up cap...there were several other undertray sections but just the small section was all that was needed. I was then able to squeese my hand in and remove the quick release fill up pipe...there are two pipes but the fill up pipe is the much wider pipe....I had to sqeeze together the two green compression sections of the quick release hose and off it popped...

I then stuck a pipe onto the tank and when I did this the fluid started to pour out the sides, it looks like there is a one way spring loaded valve so when you push the pipe in then it lets all the adblue run out the sides, I grabbed a bucket and caught about 6litres.

After draining out the 6 litres I reconnected the quick release fill pipe.

I then turned the ignition on and left it for around 60 seconds, but no change.

I went for a drive and kept switching off and on waiting 60 seconds before starting the car but again no luck...I did this again and again for the next 24hrs but with no change.

The next day I added around 4litres back in, I'm guessing that left about 2-3 litres before overflowing, switched the ignition on and with in about a second it immediately registered 6000miles...I didn't even need to wait 30 seconds or go for a drive.

Thank god it's fixed as I really didnt fancy an expensive visit to the dealer or worse having to replace anything...

So I guess the moral of the story is don't overfill the adblue tank, only add the required amount shown on the dash inside the car.


Thanks everyone for the help, you all saved the day

Ok so I had to do this fix again after around 4000 miles, so I didn’t get the 6000 it had originally registered.

So I followed my original guide above and again slid a screwdriver into the fill up duct ( after removing the wider of the two pipes ) in the adblue tank to drain the tank ( it seems to have a spring loaded valve so nothing will drain out unless you wedge it open ) but this time I left it until the flow pretty much stopped.

I then went for a drive around the block, stopping and starting to see if it would reset but no luck.

I then went home and added exactly 4300ml of ad blu.

Turned on the ignition and bing it instantly registered 5000 miles.

So the reason I updated this guide is I now know how much to add after the tank has been drained.

Hopefully this helps someone in a similar case as now I’ve provided some measurements 4300ml from an empty tank maybe it will also work for others.

I just got my van other week and after 1 day of driving got error adblue with spanner and from 4500mil become 650mil was lucky to do image of it or would not know how much was when van arrived.

Only what I did was to tank diesel but i notice when I stoped in shop fans was still on there I assume regen was trying to be done I could be wrong here but was a bit strange.

Next day I called seller and asked him about it and if he did top up as I read here about problem with overfill he did not as he dint know how much was already he say try top up and see if set itself up if not then to call him back.

Before top up I did try see how much its and with help of plastic long piece go quiet far and only on end was wet. I decide to top up 5l and see if anything change and for now nothing did but I might overfill now

I got VCDS but a dongle its a fake one and can use only up to 2015 and its showing errors but module its unknow.

I just buy new one this time dint bother 2nd hand as last one was fake lol will post exactly errors when will arrive.

I might as well remove adblue from tank and see if that help I did purchase as well that solution to help fight crystallisation.
