Llanwrtyd Wells: AdBlue in the Diesel Tank? Leave It Off
If AdBlue has gone into your diesel tank, leave the engine off then keep the ignition off. AdBlue is urea mixed in water. Not like fuel, it neither ignites nor mixes, and no harm happens until the motor sucks it round. In Llanwrtyd Wells, AdBlue in a diesel tank found before the motor runs normally comes down to a drain and a thorough flush, right where your car is. Ring 0333 366 0103 before you do anything else.
Your next steps right now, Llanwrtyd Wells: AdBlue in your diesel tank
Do:
- Pocket your keys, which prevents someone switching the electrics on.
- If you are at all near moving traffic, put your hazards on.
- Hold on to the till receipt or the empty bottle, so you can tell us what was put in and about how much.
- Our van locates you quickest with a postcode starting LD5 4, or simply the name of a street close by, so phone from the car.
Do not:
- No starting your engine — not for a second, not to shift the vehicle.
- Don't switch the ignition on. On many diesels that alone runs the fuel pump.
- Pouring in extra diesel does not help: AdBlue settles out rather than blending.
- Any driving at all is best avoided, including a short distance along Riverside.
- No emptying it yourself, either, at the roadside.
Ask the people behind the counter to help you move the vehicle off the island if you are at a forecourt in Llanwrtyd Wells, whether it's the Oil4Wales or elsewhere. At your own drive, don't move it at all.
AdBlue in a diesel tank, and what it does there
AdBlue is made for the exhaust, not the engine. It goes into its own tank and is sprayed into your exhaust gas to clean it. A fuel pump isn't made to take it, and AdBlue was never supposed to travel through one.
It doesn't blend. Once it is tipped into a tank of diesel, AdBlue acts not at all like fuel. It sinks, because it is heavier than diesel, and settles low where the pickup takes its fuel from. The first thing the system pulls through, once it runs, is the AdBlue. So a motor that had AdBlue poured in on a drive in Tirabad last night, and hasn't been started since, is still the straightforward case: the AdBlue is lying at the bottom of the tank, and nothing has pulled it in.
Once it's drawn in, the damage takes two forms. Crystals and corrosion. As the water dries, it strands urea that hardens in filters and narrow channels; meanwhile, since it attacks certain metals, each part it reaches suffers for as long as it stays inside. Overnight, a car sitting in Llanwrtyd Wells with AdBlue in its lines gets worse; if it's only in the tank, nothing changes. Water protects nothing. The injection pump and each injector depend on diesel running through them, so the water content damages them by itself.
AdBlue in a diesel: why it's commonly worse than petrol
Put petrol in a diesel at the Pace and you have a fault of thin fuel. No damage is done while it sits unused, blended into your diesel — only once the engine runs on it.
With AdBlue in a diesel, the liquid itself is simply the wrong one. It can't just be run through, because it doesn't burn. Whether your car is in Llangammarch Wells or the heart of Llanwrtyd Wells, firing it up "to see" costs more with AdBlue than almost any other mistake, and the flush counts more. Why: it won't remain mixed, and so diluting it fails; and crystals and corrosion survive the following tankful.
The same good news holds as with petrol. Wherever around Powys your vehicle has come to rest, an unrun motor leaves the AdBlue still in the reservoir: the easiest part of any fuel system to empty.
AdBlue in a diesel tank around Llanwrtyd Wells: how it ends up there
In dim light, two caps side by side — the AdBlue cap and the diesel one, now and then under a single flap — may look the same. No one means it; many designs invite it. It usually happens at home, from a container grabbed en route home, not at the forecourt.
It tends to take place in a couple of familiar ways. The refill is hurried outside the local primary school, because your dash flashed with a warning as the children were taken off. After work, a bottle goes in on a drive near Irfon Crescent. Or someone unfamiliar with that flap tops up the vehicle in dim light, stopped in the car park outside Stonecroft Inn.
It crops up most in a hire car, a brand-new car, a company vehicle, or the spare car of a family with one of each fuel types — the vehicles drivers know least. Wherever you're in Llanwrtyd Wells or the remainder of Powys, it's the same error and the same first answer: leave it off.
AdBlue in your diesel tank in Llanwrtyd Wells, and your engine started?
Then the tank is no longer where the AdBlue is. Given any running time, it travels to the injection pump and every injector, after passing through the filter and lines.
Perhaps returning from Dolwen Fields, or part way across Llanwrtyd Wells, your engine may run rough, smoke, drop power, flash your dash or cut out. Once safe, stop then turn it off — with no restarting to see. Each start pulls more of that through.
Exit the M4, under 50 miles from Llanwrtyd Wells, at the next junction and stop safely, not driving on.
Hopping across Llanwrtyd Wells to the car park by St James' Church is one thing; heading towards Swansea, under 50 miles away, is another, because every mile carries the AdBlue deeper in. So mileage matters. Let us know roughly how far it had come.
Wherever your car came to a stop is where all of it gets done, even with more to rinse out after your engine has been running. If it is caught quickly, long-term damage is very rare.
Llanwrtyd Wells: how AdBlue is emptied from a diesel
Wherever it has stopped in Llanwrtyd Wells — a filling station, a lay-by, a drive, a road beside Victoria Hall — the van comes to your vehicle. Before anything else our engineers ask what got in, about how much, and whether the engine has been run, because those answers decide this work.
Then the tank is emptied where the car stands, so the contaminated fuel and the AdBlue come out together. What remains from AdBlue won't flush out by itself, so the whole system gets a careful flush, which counts much more here than for petrol. Fresh diesel goes in once your filter is flushed — or swapped, if it needs to be — and then the vehicle is tested. If the engine has not run, the majority of jobs take about half an hour once our technicians arrive. Explosion-proof pumps mean a busy forecourt sensible to work on, and they run quiet enough not to disturb the neighbours at night.
Bleeding the fuel system with fresh diesel comes last. You head off as soon as our engineers have started it, and it makes no difference whether your car is on a drive in Llanwrtyd Wells or in a space at Llanwrtyd. Our technicians make sure it runs correctly on new diesel before leaving. The entire job is done where the car is, so it never has to be taken to a garage. Your insurer will want an engineer's report and the VAT invoice — each handed over afterwards.

What AdBlue in a diesel tank costs to put right around Llanwrtyd Wells
Since the jobs differ, a flat price would not be honest. What moves the price is, firstly, whether the motor has run and for how long; then how much AdBlue was put in; and after that where your car is and whether our van can reach it safely, which is simpler on an open drive than in a tight space behind Galvanistic Methodist Chapel.
That's why each call from Llanwrtyd Wells starts with the same three questions, asked before giving a figure, not after: what was put in, how much, and if it's run. The replies turn a range into a straight quote.
Our price is given during the call, before a van sets off; settling up happens on the day, by card or over the phone, and nothing upfront. While the van is travelling, dig out your policy: plenty include misfuelling.
