Welshpool: AdBlue in the Diesel Tank? Leave It Off
Engine off, ignition off: that's where you start if AdBlue has got into the diesel tank. Urea dissolved in water is what AdBlue is. As it is water-based, it won't burn and won't blend with diesel; trouble just starts when your pump starts drawing it. In Welshpool, AdBlue in a diesel tank found before your motor runs usually means a drain and a thorough flush, just where the vehicle is. First, ring us on 0333 366 0103.
AdBlue in your diesel tank in Welshpool: the first few minutes
Do these:
- Pull your keys out, and so no one switches your ignition on.
- Hazards on, if moving traffic is anywhere near.
- Keep the receipt or the empty bottle, so you can tell us what was put in and roughly how much.
- Our van locates you fastest with a postcode starting SY21 7, or simply the name of a street nearby, so call from the car.
Not to do:
- Don't start your motor, even for a moment to move the vehicle.
- Many diesels power their pump the moment your ignition goes on, so leave the vehicle off.
- No extra fuel on top. The AdBlue won't blend, so it's pointless.
- Leave it where it is rather than driving it anywhere, even a short way along High Street.
- No draining it yourself, either, at the roadside.
The staff working at any Welshpool forecourt — the Ballard & Son included — will normally lend a hand rolling it aside if you ask. At home, your car remains just as it was left.
What AdBlue does in a diesel tank
Made for the exhaust, AdBlue has no place in your engine. It goes into its own tank and is sprayed into the exhaust gas to fresh it. Neither side fits the other: urea does not belong in a pump, and a pump can't take urea.
Inside a diesel tank it acts really differently from fuel. It does not mix in. The pickup takes fuel from the lowest part of your tank, and that is precisely where AdBlue settles: being denser than diesel, it sinks. When the system runs, the AdBlue is first to go through. Until then it waits underneath your diesel, and that is how a car topped up in Llanerchydol last night and not switched on remains the simple case, as long as nobody turns your key.
From there it causes two kinds of harm. What is left when the water goes is urea, which forms crystals: they lodge in tiny channels and block filters. On top of that, it eats at certain metals in a fuel system, and carries on till it is cleared out. A car left standing around Welshpool with AdBlue already in its lines is worse by the morning; one with AdBlue only in its tank is not. Diesel protects the high-pressure pump and every injector as it flows; water gives no lubrication, and that is a separate kind of harm.
Petrol or AdBlue in a diesel: why AdBlue is frequently worse
Fill a diesel with petrol by mistake over at the Tesco, and this issue is diluted fuel. Harm only comes from running on it. Mixed into the diesel and left inside your tank, it does none.
With AdBlue in a diesel, the liquid as such is plainly the wrong one. Because it does not burn, running it through isn't an option. Whether the car sits in Gungrog or the heart of Welshpool, turning it over "to see" does more harm with AdBlue than almost any other mistake, and the flush counts more. Why: it will not stay blended, and so watering it down is impossible; and crystals and corrosion survive the next tankful.
With AdBlue, the good news is no separate from petrol. Not run? Then the AdBlue sits only in your tank, the easiest bit of the whole system to clear, wherever your vehicle has come to rest around Powys.
How does AdBlue end up in a diesel tank around Welshpool?
No one means to do it. The AdBlue filler on plenty of vehicles sits right next to your diesel filler, at times under the same flap, and the two caps can look alike in poor light. Mostly it's not the forecourt: a driver picks up a container driving home and pours it in outside the house.
The ways it occurs are few and familiar. The refill gets hurried outside the local primary school, after your dash flashed with a warning while the kids were taken in. A bottle is poured in at the end of the day on a drive just off Jehu Road. Or a driver unfamiliar with that flap refills your vehicle after dark, stopped in the car park outside The Pheasant Inn.
The least known vehicles see it most — hire cars, brand-new cars, company ones, and the spare motor in a family with both fuel types. Same slip, same first step — leave it off — anywhere you happen to be in Welshpool or the remainder of Powys.
Welshpool: started your engine with AdBlue in the diesel tank?
Then that tank is no longer where the AdBlue is. It's been pulled through the filter and the lines, and if your motor ran for any time, it has got to the high-pressure pump and the fuel injectors.
Expect lumpy running, exhaust smoke, falling power, warnings on the dash, or a cut-out — returning from Bron-Y-Buckley Wood, perhaps, or part way across Welshpool. No starting it again to check: pull over once it is safe, then turn everything off. With each start, more of that is pulled through.
On the M54, under 50 miles from Welshpool, the next junction is where to exit, and somewhere sensible is where to park — not driving on.
Every mile pushes the AdBlue deeper in. That's why a hop across Welshpool to park beside Launderette and a drive of under 50 miles towards Wrexham are very different jobs. Roughly how far had it come? Tell us.
We do all of the flushing where your car has ended up, and once your engine has been run there is more of it. Very rarely does it leave long-term damage when it's caught early.
Clearing AdBlue in a diesel around Welshpool: what it takes
Anywhere it has stopped in Welshpool — a forecourt, a layby, a drive, a street beside Welshpool Town Hall — the van comes to the car. Three answers decide the work, so before anything else our engineers ask what went in, roughly what quantity, plus whether your motor has run.
Then your tank is emptied where the vehicle sits, and so the tainted fuel and the AdBlue come out together. A full flush matters far more with AdBlue than with petrol, because residue will not clear away by itself. The filter is cleaned, or replaced where it needs to be; fresh diesel goes in; and your car is tested. If the engine has not run, most jobs take about half an hour once our engineers are there. Our pumping gear is explosion-proof, so a live filling station is no issue, and it's hushed enough for a residential street after dark.
The final step is to bleed the fuel system on fresh diesel. You head off as soon as our engineers have fired it up, and it makes no difference whether the vehicle is on a driveway in Welshpool or in a space at the nearest station. It is checked on clean diesel to make sure it runs correctly before we leave. Our technicians do it all wherever the car has ended up, and it never has to be taken to a workshop. You receive a VAT invoice and an engineer report after that, which is what insurers ask for.

AdBlue drains across Powys, Welshpool included
Over the SY postcode area, the vans taking AdBlue call-outs around Welshpool serve most of Powys too, Burgess Lands, Groespluan and Coed-y-wlad included. Close to a border, or somewhere tricky to pin down? Checking is better than assuming, so phone.
A van that comes to you fits Welshpool, a riverside town: you have no need to take your car to us, because our engineers drain it on the spot, in a driveway, a side street, a parking area or a forecourt.
What does AdBlue in a diesel tank cost to sort out in Welshpool?
No flat figure could be honest, since each job is different. 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 car is and whether a technician can get to it safely, which is easier on an open driveway than in a tight gap behind Welshpool Methodist Church.
Before a quote, not after, each enquiry from Welshpool opens with the same three questions: the liquid, the quantity, and if it ran. The answers turn a range into a straight price.
Our price is quoted on the call, before anyone sets off; settling up happens on the day, by card or over the phone, and nothing upfront. Many insurance policies include misfuelling cover, and so it is worth checking yours while we're on the way.
Welshpool: still beside the car?
In that case, do nothing — that is the most helpful step there is. Keys out, engine off, ignition off. Call 0333 366 0103 then tell us it's AdBlue, about how much, and whether it's run. Petrol in Diesel takes it from there, around Welshpool or anywhere across Powys.
