--- title: AdBlue in a Diesel Tank Earsdon? Read This canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/earsdon-tyne-and-wear/ location: Earsdon county: Tyne and Wear latitude: 55.045590 longitude: -1.498860 service: AdBlue in a Diesel Tank updated: 2026-10-10 --- # Earsdon: How Does AdBlue End Up in a Diesel Tank, and How Do You Prevent It? AdBlue already in your diesel tank? Then put this page aside a moment, keep the ignition and engine off, and call 0333 366 0103. Around Earsdon, catching it before your engine turns usually means a drain and a thorough flush on the spot. Reading in advance? In that case the rest covers how it happens and how to prevent it happening at all. ## Two fillers, two tanks: AdBlue in a diesel motor Many newer diesels on the roads around Earsdon and Murton carry two liquids, not one. Diesel goes to your motor. Its own tank keeps it, and from there it goes to your exhaust, where spraying treats the fumes. There is a filler for each tank. Other cars keep the AdBlue filler in the boot or under the bonnet; plenty more place the two side by side under one flap. Filling your diesel side at the pump happens constantly. Seldom filled, AdBlue usually goes in from a bottle, tipped by someone who must stop and think what cap to use. The slip lives in that gap. ## How AdBlue in the diesel tank happens in Earsdon It is hardly ever carelessness. Three things tend to line up. Haste follows from the warning. The car warns you as AdBlue runs low, and a dry tank puts the vehicle into limp mode — so the top-up gets done quickly, before work on a drive off Garden Terrace, or on the way home in the car park at The Cannon Inn. Next, your hand reaches for the cap it would have used on the old car — because a rental car, a new vehicle or a company car places the fillers where your last one did not. A spout-topped bottle finds no obstacle at a diesel filler no more than at an AdBlue one. And so the pour, once started, carries on. The same few seconds decide it, in the middle of Earsdon or out in Shiremoor. ## Telling the AdBlue filler from your diesel filler Be it a Earsdon forecourt or a drive over in Backworth, spend a couple of seconds on these before anything is poured in. - Where it sits misleads; the cap does not. AdBlue caps tend to be blue or bear the word "AdBlue" — diesel caps normally don't. - Look at the size: the smaller filler neck is, on many motors, the AdBlue one. - Check inside the fuel flap: plenty of cars have a label there saying which fuel goes where. - In your boot or under the bonnet: that's where your filler sits if it is not by the diesel cap, and the handbook tells you which. - Ask the person who drove it last — before you leave, not when the light comes on — if you pick up a hire or company car from somewhere like the car park outside Seaton Delaval. ## Keeping AdBlue out of the diesel tank when you top up On the day the light appears — wherever it is around Tyne and Wear — a routine to use. - Switch off once parked — level ground, motor stopped, and not rushed beside Front Street on the verge. - Daft as it sounds, speaking "AdBlue" aloud while you unscrew the cap does the trick — once you have found the filler and read it. - The diesel cap stays on. When the two sit under a flap, confirm it's closed before lifting the bottle. - Finish when the tank is topped up or the bottle runs dry; before that, pour gently using its own spout. - Only after that, start your car: close the cap, check once more, and make sure the diesel cap was never opened. If at step two or three you find you have already poured into the diesel side, stop there. Never go on to step five. ## Put AdBlue in your diesel tank around Earsdon already? Don't start the engine: that's how the short order of things begins. On plenty of diesels your ignition alone runs the fuel pump, so do not switch the vehicle on. Filling up with diesel won't thin it: rather than mixing, AdBlue drops to the base of that tank, right where fuel is taken from. If you are on a forecourt, whether it's the BP or the Sainsbury's, ask the attendants to help push the vehicle away from the pump. Leave it where it is if you are on your own drive around Earsdon. If the motor has already run, stop as soon as it is safe then switch off. Earsdon sits under 10 miles from the A167(M); there, take the next junction. A short hop across Earsdon is a smaller job than a run towards Newcastle upon Tyne, under 10 miles away, and so tell us about how far it went. ## When our engineers arrive around Earsdon, what occurs? By South Wellfield First School, near Earsdon Methodist Church or on your own drive: wherever the car has stopped, our engineers come to it. What fluid went in, the amount, and whether it ran: our engineers ask because the replies set both work and price. The quote is given on the call, ahead of any van leaving. After that: a drain, then a thorough flush of the entire system. AdBlue crystallises and is corrosive to some of the metals in a fuel system, so it does not wash out on its own — which is why the flush counts more here than with petrol. After the fuel filter has been cleaned — or renewed, where needed — fresh diesel is added, and then your car is tested. Before we leave, we fire it up and make sure that it is running correctly. Most jobs are done in about half an hour once we arrive, as long as your engine hasn't run — and the pumps we use are fine on a live forecourt yet quiet at night outside a house. Your insurer will ask for the engineer's report and the VAT invoice, and both are yours at the end. Payment is on the day, with no money upfront. Before we get there, take a look at your insurance documents; plenty include cover for misfuelling. ## About Earsdon itself Earsdon is a small village in Tyne and Wear, situated on the coast of north-east England, approximately 6 miles from Newcastle upon Tyne.
