Don't Start It: AdBlue in a Diesel Tank in Maes Maelor
Motor off, ignition off: that is how you start if AdBlue has gone into the diesel tank. Urea mixed in water is all AdBlue is. The harm starts once it is sucked through the lines — it will not ignite, and it will not blend with diesel. Caught before your motor has run, AdBlue in a diesel tank is normally a drain and a thorough flush, done where your car is around Maes Maelor. Before you do anything else, phone 0333 366 0103.
AdBlue in the diesel tank around Maes Maelor: the first few minutes
Do these:
- Keys out — that way nobody can switch anything on.
- If you are anywhere close to moving traffic, put the hazard lights on.
- Which fluid, and about how much volume? Save the bottle or the receipt, and we can know.
- Tell us a postcode starting LL11 5, or whatever street lies closest, and the van finds you directly — so ring from wherever you stand.
Things not to do:
- Not even briefly, and not to roll your vehicle: the engine stays off.
- The ignition remains off: on lots of diesels, switching it on is enough to run your pump.
- Do not top up with diesel to dilute it. AdBlue doesn't mix in diesel; it separates out.
- Even a short stretch up Llanarmon Road is too far to drive the vehicle.
- Don't try to drain the car yourself at the roadside.
Get the attendants to help you roll your car off the island if you are on a forecourt in Maes Maelor, whether it's the Asda or elsewhere. If you are on your own drive, leave it just where it stands.
What AdBlue does in a diesel tank
The motor is not what AdBlue is made for; the exhaust is. It goes into its own tank and is sprayed into the exhaust gas to clean it. No part inside an injection pump is made for this liquid — and none of that was intended to go through one.
Inside a diesel tank it behaves very differently from fuel. It doesn't mix in. It sinks, since it's heavier than diesel, and settles low where the pickup draws its supply from. The first thing the fuel system pulls through, after it runs, is the AdBlue. So a motor that had AdBlue poured in on a drive in Blaenau last night, and hasn't been started since, is still the straightforward case: the AdBlue is lying at the bottom of that tank, and nothing has sucked 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 remains there. If the AdBlue is in the pipework, leaving it overnight around Maes Maelor leaves things worse. In your tank alone, time does nothing. And there's the water: it brings no protection to the parts that rely on it most — the high-pressure pump and each injector.
Petrol or AdBlue in a diesel: why AdBlue is often worse
Top up a diesel with petrol in error over at the Shell, and this problem is diluted fuel. It mixes with the diesel, and while it is in that tank it causes no harm; the damage comes from running the engine on it.
With AdBlue in a diesel, the fluid itself is plainly the wrong one. It does not burn, so it cannot simply be run through. Deposits and corrosion remain after the next tankful, and AdBlue separates again out of the diesel, so watering it can't work. Hence the flush matters so much, and trying your engine "to see" does more harm here than almost any other slip — in Bedlwyn or the heart of Maes Maelor equally.
The same good news holds as with petrol. If the engine hasn't run, the AdBlue is still inside that tank, and that tank is the easiest part of a fuel system to clear, wherever across Flintshire the car is sitting.
How AdBlue ends up in a diesel tank in Maes Maelor
Plenty of motors put the AdBlue filler alongside the diesel one, now and then behind a single flap, and after dark the two may appear identical. No one intends it. A bottle bought while driving home and poured in at home, rather than at the forecourt, is the usual story.
Mostly, it occurs in one of a couple of familiar ways. Halfway through the morning drop-off, the dashboard warns, and outside the local primary school the refill is hurried. A bottle is poured in at the end of the day on a drive just off B5430. Otherwise, after dark by Moors Inn, your car is refilled by someone opening that flap the first time.
The least known vehicles see it the most — hire cars, brand-new ones, company cars, and the spare motor of a home with both fuels. Wherever you are in Maes Maelor or the rest of Flintshire, it's the same slip and the same first answer: leave the vehicle off.
AdBlue in your diesel tank in Maes Maelor, and the engine started?
Then the AdBlue has left the tank. It's been sucked through your filter and the lines, and if your motor ran for any time, it has reached the high-pressure pump and your injectors.
Lumpy running, smoke, lost power, dashboard lights or stalling: any may show up, perhaps midway across Maes Maelor or returning from Coed Pen-y-nant. No restarting to test: pull over once safe, then turn everything off. Every start pulls more of that through.
Exit the M56, under 15 miles from Maes Maelor, by the first junction and park safely, not carrying on.
Each mile carries the AdBlue deeper in. That's why a hop across Maes Maelor to park near Minera Union Horse Whim Circle and a drive of under 10 miles for Wrexham are very separate jobs. About how far it had come is worth telling us.
There's more to rinse out once your engine has been run, and our engineers do all of it where the vehicle has ended up. Lasting damage is very unusual when it's caught early.
Emptying AdBlue in a diesel in Maes Maelor: what it takes
Wherever it has come to rest around Maes Maelor — a forecourt, a layby, a driveway, a road by Bwlchgwyn Village Hall — our van comes to the vehicle. Before anything else our technicians ask what went in, about how much, and if the engine has run, since those answers settle this work.
Next, draining your tank right there removes the polluted diesel along with the AdBlue in one go. A full flush matters much more after AdBlue than after petrol, because what remains won't clear away by itself. Next, your filter: cleaned, or changed when it must be. Then fresh diesel, and then a test of the vehicle. If the engine has not run, most jobs take about half an hour once our engineers arrive. Quiet enough for use outside a house at night, and safe on a working forecourt, our pumps are explosion-proof.
Last, your system is bled with clean diesel. At that point our technicians fire it up and you head off, whether from a parking space outside Cefn-Y-Bedd or a driveway in Maes Maelor. The check before our engineers head off is that it runs smoothly on new diesel. No workshop is required at any point, with the whole job done then and there. Insurers ask for a VAT invoice and an engineer report, and you get both afterwards.

Maes Maelor and Flintshire: AdBlue drains across the area

Maes Maelor is a rural hamlet, and a call-out drain suits it: whether the car is on a home drive, a residential street, a car park or a forecourt, we drain it where it is, and so it never needs to be moved to us.
AdBlue in a diesel tank in Maes Maelor: the cost of fixing it
There's no fair single price, since the jobs are not the same. What moves the cost is, first, whether your engine has been running and for how long; then how much AdBlue went in; and finally where your car is and whether a technician can get to it safely, which is simpler on an open driveway than in a tight gap behind LA766 memorial.
Ahead of any quote, not after, each call from Maes Maelor opens with three checks: the liquid, the quantity, plus whether it ran. Those answers turn a range into a straight quote.
The price is quoted during the call, before anyone sets off; settling up happens on the day, by card or over the phone, with nothing upfront. As the van is on the way, check your policy: many include misfuelling.
Maes Maelor: still beside your car?
Leaving your vehicle alone is, then, the most useful move open to you. Keys out, motor off, ignition off. Call 0333 366 0103: AdBlue, the amount, and whether it ran is everything our technicians ask. Petrol in Diesel handles the rest across Flintshire, Maes Maelor too.
