--- title: AdBlue in a Diesel Tank Abermorddu: What Now canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/abermorddu-flintshire/ location: Abermorddu county: Flintshire latitude: 53.104220 longitude: -3.033750 service: AdBlue in a Diesel Tank updated: 2026-10-10 --- # AdBlue in the Diesel Tank in Abermorddu, and What to Do Next What to do about AdBlue in a diesel tank depends on one thing more than any other: if your motor has been run since it went in. Wherever the vehicle stands — Caer Estyn, Abermorddu — don't run an engine that has not run yet. Call 0333 366 0103 with your key and motor still off. Across Abermorddu, that is generally drained and cleaned where it stands. Where your engine has run, pull in safely straight away, then turn the car off. Stage one stays the same, even though the job is bigger. Compare what happened to one of the ones below, anywhere in Flintshire you happen to be. ## On a Abermorddu forecourt with AdBlue in a diesel Only now, bottle still in your hand, you realise that the cap you opened was the wrong one, there at the petrol pump. Be it Gulf, Shell or anywhere else in Abermorddu, the case is identical. Put simply: there is no better spot to be to spot it. Nothing has pulled it in, so the AdBlue sits just inside your tank. What to do: don't get back in and fire it up to clear the pump. Phone us from the forecourt once your vehicle sits in a bay — the attendants will help push it — then keep the receipt. Emptying it right at the pump is possible if it can't be shifted, since the equipment is explosion-proof. ## At home around Abermorddu with AdBlue in your diesel tank The warning light had been on for days. You bought a bottle, poured it in on the driveway, and only when you put the empty bottle in the recycling did you look again at the cap. It occurs on drives just off Maes Cibyn as regularly as anywhere. What it means: if you have not driven since, this is nearly as good as the forecourt. At the bottom of your tank is where AdBlue waits, because it won't mix with diesel — and a night passing changes nothing of the difference. Keep the keys in the house overnight — otherwise a person may drive it away first thing — and call us. Your driveway is where it gets emptied, be it in Abermorddu or Bridge End. Late-night drains outside a house are no problem: the pumps are quiet. ## Drove off with AdBlue in a diesel around Abermorddu? Topped up, drove away, and before long the engine was running unevenly, blowing smoke, losing power, or lighting up the dash. Maybe it was on Pughs Yard, perhaps on the way out towards Wrexham, under 5 miles away. The point: your system has pulled AdBlue in already. Past the fuel filter, through the lines, and — the more the mileage — on into the injection pump and each injector. More miles, more restarts: deeper it goes. What to do: pull over where it is safe to do so and switch off. Exit by the next junction — not the services further along — if you're on the M56, under 15 miles from Abermorddu. No test restarts: clearing itself isn't something AdBlue will do. Phone, and say how far the car was driven. ## AdBlue in the wrong tank of a hire, lease or company car It is a vehicle you have had for a week. On your own car, AdBlue is missing or elsewhere. On this one, its inlet is just by the diesel cap — a surprise to you. It can happen to anyone, anywhere across Flintshire. In short: one extra stage on top of the cases above, and those depend on if it's run. The owner frequently has to sign off any work, under many rental and company contracts. Next: ring the rental company or the fleet manager first, and then us — sorting it before we arrive is faster. Stuck by Caergwrle Castle or at Caergwrle till someone answers, the car stays switched off the whole time. ## Not sure it was AdBlue in your diesel tank, Abermorddu? Sometimes the fair answer is "I think so". The bottle is lighter than it should be, there is a faint smell of ammonia round your filler, and you can't remember which cap you took off. A hurried stop by the gates of Dodleston CofE Primary School, or a call to a friend in Hope: either fit. The upshot: the motor is not harmed by a little AdBlue splashed around the filler. The diesel tank with AdBlue in it is another matter. If there is AdBlue in that tank, firing up your car would suck it in, and it wouldn't tell you which either. Take it that it got in, and don't start your key. Call us and describe what you saw; we'd rather check a tank that turns out free of AdBlue than drain one that has already been run. ## The common ground in every Abermorddu AdBlue drain The work opens the same way, whatever your situation. Anywhere the car is — Ye Olde Castle Inn's car park, a street beside The Packhorse Bridge, a drive, a forecourt — our van gets there and we ask about the liquid, the amount, and whether the engine has turned over. Over the phone, before dispatch, you hear our quote, and those answers decide the job too. Emptying that tank comes first, followed by a full flush — more important after urea than after petrol, since crystals and corrosion will not clear by themselves, no matter how long it sits. Next comes the filter — cleaned, or replaced when needed — then fresh diesel, and a test of the vehicle. The majority of unrun cars are a half-hour job from the moment our engineers turn up. The final step is starting the car. Before we leave, it's checked to be sure it runs properly on fresh diesel. Our technicians do the entire job where the vehicle is, and long-term damage is very unusual when it has been caught soon. Nothing is paid upfront, payment happens on the day, and you receive what your insurer asks for: an engineer report plus a VAT invoice. It is worth knowing: lots of insurers offer misfuelling cover, and so a check of your policy while you wait is worthwhile. ## About Abermorddu and where it is Abermorddu is a small village in Flintshire, situated on the banks of a river at an elevation of 93 metres.
