AdBlue Overflowing when attempting refill - still showing empty

So currently got a rental peugeot 3008 sitting on my driveway. The top up AdBlue light came on whilst I was driving back from Heathrow overnight and I had no idea what it was, having never heard of Adblue. Anyways now it won't allow me to start the vehicle without topping up. I have been out and purchased some adblue but after putting in a small amount (maybe a litre?) it just started to overflow all over the driveway. It won't take any more and it seems to be full up to the cap. I have been on hold to the Avis breakdown line for about half an hour so just wondering if anyone has any advice on how to sort this out whilst I wait in the queue? Could the cap be blocked somehow and is there any way to easily fix this? Might the level settle down after a while and allow me to put more in? I have had a look around and the tank should be around 17 litres or something so it should've all gone in fairly easily but it's not happening. According to the manual you need to top up a minimum 5 litres if it is empty and it definitely hasn't taken as much as that so far.
 
Adblu is a pain in the rear, it crystallises and gums up sensors all the time, it’s the bane of my otherwise faultless Scania truck, it’s not once let me down on the road but goes to the Scania dealer frequently outside of its inspection intervals due to bloody adblu.

As said, almost certainly a sensor issue.

It's the same with our buses. Although it's usually the injection system that it clogs (according to our engineering dept). Issue being that as soon as the system can't add the adblue when it should, throws the whole vehicle into limp mode which kills all power and the bus can't go over 8mph

Scania’s setup basically detects an issue then gives you a countdown before it reduces engine power - usually 35 engine running hours - which puzzles me, surely if there’s an impending problem then why the countdown? Basically it’s fine for those 35 hours of running but at 35:01 the engine barely gives enough power to pull the truck when empty, never mind laden!

We’re told it’s sensors that fail although I’ve found it gets upset if you overfill the adblu tank also.
 
Well sounds like you guys were right. Avis sent the AA round and the bloke spent about an hour trying to get it going before admitting defeat. He reckons a sensor issue and his software couldn't get round the driving block so it's been towed. He also said that he gets called to similar adblue issues all the time, another reason not to buy a new diesel car I guess...
 
transits also had this issue, when getting low the countdown starts ....ignore it at your perile. once it ticks over no start and main dealer recovery. even then ive had some customers lose there vehicles for a few weeks cause the dealer had struggled to reset the system.
 
We've had a few Peugeot partner vans suffer with this and Peugeot have refused to cover it under warranty to my knowledge.

Edit to say I believe it's more than just a sensor, in my head the repair cost was circa 1500 quid
 
As soon as the warning came up I put 5L in and problem solved.
I certainly didn’t wait for the countdown.
I’m not filling the tank as 5L will last long enough for the miles we do and as others have said ad blue crystallises.

We just have a display for tank level. ≤15% level. Stop, call control. Usually, unless you've only one run left, you're turfing off passengers and going straight back to depot.

Because the engine would happily keep running without it but you are not meeting emission requirements.

I understand this, but don’t see the reason for the countdown, the fault has arisen so it’s not meeting emission requirements, fair enough, surely the time is then to get a call out / repair (the vast majority of trucks are under some form of repair and maintenance contract) it just strikes me as odd that you have 35 hours of engine running time with the fault before it effectively forces you to address the issue, whilst in some applications that’s a few days, in others, it could be weeks….

Presumably that's the figure Scania's engineers settled on to sensibly allow the majority of use cases to resolve it by returning to a base depot (where said repairs may be simpler or cheaper or allow the driver to swap to a spare vehicle easily), rather than needing a remote/roadside call-out but equally not just letting it be completely ignored indefinitely.

It is meeting the emission requirements.
The warning is telling you the levels low and it soon won’t be.

Ablue pumps on Peugeot stuff. We've replaced all the french rubbish on our fleet. hoping the Ford transit couriers are better.
 
The adblu level? - I ask as I’ve had this warning with my adblu level at 100% more than once….
The vehicles I have experience of give the warning when the levels low.
You’ve obviously more experience than me being a professional diver of different vehicles.
I would say my comments are accurate for light vans and cars.

I think they pay so little for the vans even this expense is nullified, I want an electric one (new toy an all that) but they've trial with area managers and decided against.

As a group we get a massive discount on Peugeot stuff. New Bippers a few years ago were less then £6k. But it was a false economy as they didn't last and were being killed at 80k miles. So moved to Partners because they were around 10k. Now onto fords at 17k. Lets hope they go the distance. Breakdowns are a nightmare for us
