--- title: What Now? AdBlue in a Diesel Tank Coronation canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/coronation-durham/ location: Coronation county: Durham latitude: 54.645210 longitude: -1.654830 service: AdBlue in a Diesel Tank updated: 2026-10-22 --- # AdBlue in the Diesel Tank in Coronation: What Now? One thing matters most when AdBlue is in a diesel tank, and it is if your motor has run since. If it has not, keep it that way, whether your car is around Coronation itself or out in Oak Street. Keep nothing on, call 0333 366 0103, and expect a proper flush after a drain, done right where the car sits around Coronation. If it has run, stop as soon as it is safe then switch off. Stage one stays the same, even though the work is bigger. Find the scenario below that matches yours, wherever in Durham it happened. ## Coronation forecourt: AdBlue in a diesel at the pump Imagine it: stood by the petrol pump, holding the bottle, you realise the filler you opened was not the right one. Whether JET, Asda or somewhere else around Coronation, the situation is identical. In short: there is no better place exists to discover it. The AdBlue is in that tank and nowhere else. Nothing has drawn it in. Clearing the petrol pump is no excuse to start it — and so don't get back in. Three things: a shove into a bay with the attendants assisting, the receipt saved, and a ring to us from the forecourt. Our equipment is explosion-proof and fine on a busy forecourt, so a car that can't be pushed clear gets cleared where it is at the petrol pump. ## AdBlue in your diesel tank on a Coronation drive? The warning light had been on for days. Only by the recycling, the empty bottle in your hand, did you look back at the cap you'd used on the driveway. Drives close to High Street see it as much as anywhere. Meaning? Provided the car has not moved since, it is close to the pump case. AdBlue doesn't mix with diesel; it sinks to the bottom of that tank and waits there. Overnight does not change that. What to do: leave your keys inside the house so nobody moves your car in the morning. Then ring. Out in Beech Terrace or right here around Coronation, the drain happens at your driveway. Late-night clears outside a house are no problem: the pumps are low-noise. ## Drove off with AdBlue in a diesel in Coronation? A short way beyond topping up, your engine began playing up: roughness, smoke, lost power, warnings on the dash. Possibly it was on Oxford Street, perhaps on the way out towards Durham, under 10 miles away. In short: the AdBlue has been pulled into the fuel system. Past your filter, along the lines, and — the more the mileage — on into the injection pump and each injector. It travels further with every mile covered and each restart. What to do: pull over where it's safe to do so then switch off. Coronation lies under 10 miles from the A1(M); on it, come off at the next junction instead of pushing on for the services. No trial restarts: clearing isn't something AdBlue does. Tell us know the mileage driven as you call. ## AdBlue in the wrong tank: hire, lease and company cars A week back, it was new to you. Unbeknown to you, the two inlets sit side by side here — not like your own car, which has none or keeps it elsewhere. It can happen to anyone, anywhere in Durham. Meaning? Whatever applies above counts too — run or unrun — plus one extra stage. Many hire and fleet agreements need the owner's sign-off for repairs. What to do: ring the hire firm or your fleet manager first, then us. That is quicker settled before we get there than after. Leave the car off as the reply arrives, whether you are waiting outside Bishop Auckland or near St Mark's Church. ## Not sure it was AdBlue in the diesel tank, Coronation? Sometimes the fair answer is "I think so". Lighter, that bottle; a hint of ammonia near your filler; no clear recollection of the cap. Sound familiar? Perhaps it happened in a hurry at the school gates at Prince Bishops Community Primary School, or on a friend's drive in Regent Street. Meaning? Spills around the inlet don't touch your engine at all. A diesel tank with AdBlue in it is a different story. You cannot tell which by turning the ignition, and doing so would draw in any AdBlue that is in that tank. Next: assume it went in, then leave your engine off. Describe what you noticed on your phone. A clear tank looked at counts as a better outcome than a run one drained. ## What each AdBlue drain around Coronation has in common Whatever the situation, one opening applies. Wherever your car is — The Red Alligator's car park, a road beside The Valley Methodist Church, a driveway, a filling station — our van arrives and we ask about the fluid, the amount, and if the engine has been run. Over the phone, before dispatch, you are told the quote, and those replies shape the job too. Then your tank is emptied and the fuel system flushed thoroughly, which counts more with AdBlue than with petrol: AdBlue crystallises and is corrosive to some of the metals in a fuel system, so it does not rinse out on its own. Then is the fuel filter — cleaned, or replaced where necessary — then clean diesel, and a test of the vehicle. If the engine hasn't run, the majority of jobs take about half an hour once we're there. Last, our technicians start the engine. Our test that it runs smoothly on fresh diesel comes before we go. Our technicians do the entire job where your car is, and long-term damage is very unusual if it has been caught soon. Payment comes on the day, never in advance. For your insurer, you get a VAT invoice plus a report from the engineer. Dig out your insurance before we're en route: cover for misfuelling comes included in plenty of policies. ## About Coronation and where it is Coronation is a village in County Durham, situated on the riverside at an elevation of 108 metres, with terraced housing being the predominant type of accommodation.
