Adblue Remap

As anyone had adblue mapped out on 2l boxer van I find the adblue a pain been told it will still pass M O T  no signs of it been removed

It’s part of keeping the emissions within the required levels. I’d not risk the van failing its MOT by tinkering with it.

What's the problem with topping up the AdBlue?

It may be inconvenient, but it's illegal to disable any emissions control device. So in legal terms - no you cannot.

I thought from the header that this would be about a map showing all filling stations with Adblue pumps, which would be useful. On two occasions now I have bought Adblue in 10 litre cans where the supplied filling spout is not quite long enough to trigger the flap in the Boxer filler fitting.

You are not alone, see my thread from last year!

I only ever use pumps. That way it's no harder than putting diesel in, and it's only every 4,000 miles anyway (11 litres when the warning first starts, at a cost of £12-15). Pumps are more common on the continent, though. Are there any in the UK? I don't mean the unpleasantly crusty truck ones which I'm not sure you should be using, as apart from the risk of contamination from the nozzle, they have a higher flow rate. I'm talking about the stay-clean type, specifically for passenger vehicles, found on the same pump islands as the diesel pumps. I don't recall seeing any of those in the UK yet.

I think interfering with the engine software to stop it using AdBlue has its own risks. What if elevated emissions are detected somehow at MOT time? And when you go to re-enable it, it doesn't work anymore because it's not been used regularly enough. And what about other side effects? And what if the dealer overwrites the engine software at a service? Mine was done in April this year as part of an engine software related recall.

I know you can also get an AdBlue emulator which is a small CANBUS-connected box which pretends to be the pump, tank, sensors etc. Obviously detectable though.

These things might turn out to be necessary to keep a vehicle working in the far future if parts or AdBlue become scarce, but for the foreseeable future I'm not convinced.

In addition, I have no doubt you would invalidate your insurance as well.

I don’t get why anyone would get a remap of any kind, especially knowing people whose remaps have become corrupted causing all kinds of issues & a nightmare to get resolved. As for Adblue, DPF or EGR deletes just don’t do it, if you’re having issues just get them sorted by a troubleshooting specialist like Jimmy at O’Rileys autos.

It’s a shame someone hasn’t produced an App like with LPG showing stations with Adblue pumps, like you I find trying to decant Adblue from a container a nightmare & the pumps at the service stations are just so much easier & definitely the way to go.

It is not a problem finding adblue it is cost to keep it working it as cost me £424 up to now in parts

Sorry, what parts?

Filling AdBlue was hard on my 2017 van because most 10L containers at garages are not long enough to open the flap in the van filler tube.
Then I discovered my (patent pending) filler device,

Isn't it. I don't know why the UK rollout of pumps seems to be non-existent.

I think you’ve been very unlucky but I think you’d be unwise to modify your van.

I have talked to other owner with same problem I also have friend who had adblue spray jet block cost of repair &650

Yet we’ve had 3 vans with AdBlue and had no trouble at all with the system.

Jimmy at O’Rileys Autos says the only time he sees problems with Adblue systems is when people wait till the Adblue warning comes up on the dash or when they let it run right low, his advice is to top it up regular & says if you do this you won’t see these kind of issues, how accurate that is I have no idea… but judging by his troubleshooting skills I’ll personally take heed of his advice.

Problem with that is AdBlue has a shelf life and if you are not doing many long trips.

Most garages sell adblue in cans but cheapest place is screwfix or B&Q when they have it. Kevin

I don’t know the chemistry but if spilt adblue is left on a surface it rapidly dries and leaves a sediment. Perhaps dried adblue on the walls of a partially empty tank gets washed into the system and causes blockages? That could indeed suggest that it is best to top up the tank after every trip and keep the tank full, particularly if the vehicle will stand for a while. I suspect that adblue was designed for trucks which will have a regular throughput of the stuff, keeping sediments at bay.

As far as I can tell, it survives perfectly well inside the sealed and airtight tank on the vehicle, where it is not even exposed to light. It can't evaporate in the tank. My van doesn't move for several months at a time, and I never top it up until the warning light comes on. And only then from a pump. No overpriced containers of questionable origin. If anything, it seems to me that repeatedly adding small quantities is more likely to cause a problem.

I always add half a bottle of anti-christalliser when filling the adblu tank, this is a must if you leave the van parked up for a while.

Thank you! Crystallisation was the word I was looking for but I could only come up with “sediment.” The Wynns stuff could be worth a try even though I am wary of potions in bottles! Sounds cheap enough.

I think it's just a very stronge detergent, I've just noticed one bottle is enough for four fills, whoops.
