AdBlue in a Diesel Tank in Glan-Duar? Don't Start It
AdBlue in your diesel tank? Then leave your motor off — and the ignition as well. Urea dissolved in water is all AdBlue is. Unlike fuel, it neither ignites nor blends, and nothing happens till your motor pulls it round. A drain and a thorough flush, done where your car is in Glan-Duar, is normally what AdBlue in a diesel tank takes — if it is caught before your engine has run. Before you do anything else, phone 0333 366 0103.
Those opening minutes: AdBlue in the diesel tank in Glan-Duar
Things to do:
- So nobody can turn your ignition on, pull your keys away.
- Close to moving traffic? So put the hazard lights on.
- Keep the receipt or the empty bottle, so you can tell us what went in and about how much.
- Ring us from where you are. A postcode starting SA40 9, or the name of the closest street, brings our van to you without a search.
Not to do:
- Moving your car even a short way is no reason to start the motor.
- Switching the key to ignition alone sets the pump going on plenty of diesels. Skip it.
- Pouring in more diesel doesn't work: AdBlue settles out instead of thinning.
- Any driving at all is best avoided, even a short distance along Bro Einon.
- Draining the tank yourself by the road isn't worth trying.
Moving your vehicle away from the island is a job for staff to help with, whichever Glan-Duar forecourt you're on, the Ffordd Llanwnen Filling Station or any other. Parked on your own drive? Then it remains just where it is.
AdBlue in a diesel tank: what it does
Meant for your exhaust, AdBlue has no place in the engine. Stored in a dedicated tank, it is squirted into the exhaust to treat the fumes. No part in an injection pump is designed for this liquid — and none of that was meant to travel through one.
It does not combine. After it's poured into a tank of diesel, AdBlue acts nothing like fuel. It drops, because it's denser than diesel, and pools low where the intake takes its fuel from. The first thing the fuel system pulls through, once it runs, is the AdBlue. So a motor that had AdBlue poured in on a drive in Pencarreg last night, and has not been started since, is still the simple case: the AdBlue is lying at the bottom of that tank, and nothing has pulled it in.
It does two kinds of harm from there. As its water goes, the urea left behind crystallises, and the crystals block filters and settle in fine passages. And it is corrosive to some of the metals a fuel system is made from, so it keeps running on the parts it gets to for as long as it stays there. A car left standing in Glan-Duar with AdBlue already in its lines is worse by the morning; one with AdBlue only in its tank isn't. And there's the water: it brings no protection to the parts that need it the most — the injection pump and each injector.
Why is AdBlue in a diesel regularly the bigger problem?
A problem of thin fuel is what you end up with from filling a diesel with petrol at the Murco. It mixes with the diesel, and whilst it's in your tank it causes no damage; the harm comes from running the engine on it.
AdBlue in a diesel is another matter: not thin fuel, yet no fuel at all. It doesn't burn, and so it can't simply be run through. Crystals and corrosion remain through the next tankful, and AdBlue splits again out of the diesel, so thinning it won't help. That is why the flush counts so much, and turning the key "to see" does more harm here than nearly any other mistake — in Aber-Giar or the heart of Glan-Duar alike.
The same good news applies as with petrol. Never run? Then the AdBlue waits only in that tank, the simplest section of the entire system to empty, wherever the vehicle has stopped around Carmarthenshire.
How does AdBlue end up in a diesel tank around Glan-Duar?
No one means to do it. The AdBlue filler on many vehicles rests right next to the diesel filler, at times under the same flap, and the two caps can look alike in poor light. A bottle picked up while heading home and poured in at home, instead of at the filling station, is the typical route.
It tends to occur in a couple of familiar ways. Midway through the drop-off, the dashboard flags it up, and outside the local primary school the top-up is hurried. A bottle is poured in at the end of the day on a drive just off Heol y Dderi. Another version: darkness, the car park outside the pub in the village, and someone using that flap for the first time.
Hired motors, new vehicles, company motors, or the spare vehicle in a family with both fuels: the least familiar vehicles get it the most. Wherever you are in Glan-Duar or the rest of Carmarthenshire, it is the same error and the same first answer: leave the vehicle off.
Already started the motor with AdBlue in the diesel tank in Glan-Duar?
The AdBlue has left the tank, then. With any running time, it travels to the injection pump and each injector, having passed via the filter and pipework.
You may see your engine running roughly, smoking, losing power, showing warning lights or cutting out, possibly on the way back from Allt Llwyn-crwn or halfway across Glan-Duar. Pull over when safe. Turn off. Leave the vehicle off instead of restarting it to check. With each start, more of it is pulled through.
Exit the M4, under 25 miles from Glan-Duar, by the first junction and park somewhere safe, not carrying on.
Hopping across Glan-Duar to the car park by Aber-Duar Chapel is one thing; heading towards Swansea, under 50 miles away, is something else, because each mile pushes the AdBlue deeper in. So mileage counts. Roughly how far it had come is worth telling us.
Wherever the car came to a stop is where all of it gets done, even with more to flush after the engine has been run. If it is spotted early, long-term damage is very rare.
What does an AdBlue drain on a diesel involve around Glan-Duar?
A street by Rhyd-y-bont Chapel, a drive, a lay-by or a forecourt: wherever your vehicle has come to rest in Glan-Duar, our engineers travel to it. Which fluid was put in, roughly the quantity, and if your motor has turned over: our technicians ask before all else, because those shape the work.
Then your tank is cleared where the vehicle waits, so the contaminated fuel and the AdBlue come out together. Residue from AdBlue will not wash out unaided, and so the whole system gets a careful flush, which matters far more here than for petrol. A test of the car follows at the end, after clean diesel is added and the filter gets flushed or, if necessary, replaced. Roughly half an hour once we arrive is typical for most jobs where your motor has not run. The pumps are explosion-proof, fine on a busy forecourt and quiet enough to use outside a house at night.
The last step is to bleed your system on clean diesel. Starting it comes next, and then you head off from where your car is parked, at the nearest station or on a drive in Glan-Duar. Before we leave, our engineers make sure it's running smoothly with new diesel in. As the job is done in its entirety where the vehicle is, a garage never comes into it. At the end, you are given the paperwork for the insurer: a VAT invoice and a report from the engineer.

AdBlue in a diesel tank in Glan-Duar: the cost of fixing it
Since each callouts vary, a flat figure would not be honest. The price shifts first with how long, if at all, the motor has been running, and next with the amount of AdBlue that was put in. After that it turns on where the vehicle is and whether a technician can get to it safely, which is simpler on an open drive than in a tight space behind Llanybydder Sheep Mart.
That's why every call from Glan-Duar starts with the same three queries, asked before giving a figure, not after: what went in, how much, and whether it's run. When those are known, a range becomes a single firm number.
Priced by phone before the van sets out, it is paid for on the day — card or phone, no deposit. Many insurance policies include misfuelling cover, so it's worth checking yours whilst we are on the way.
