Caught before the engine runs, it's usually a drain and a thorough flush, done where the car is around Kellington. If you are reading before it has happened, the rest of this page is about why it happens and how to make sure it doesn't. ## AdBlue in a diesel vehicle: two tanks, two fillers Many modern diesels around West Haddlesey, as well as Kellington, carry on two fluids; your motor gets just your diesel. The exhaust, not the engine, is where AdBlue goes: dosed into the gas to fresh it, from its own tank. Different tanks, separate fillers. Plenty of motors share a single flap for both, while some move the AdBlue filler to the boot or under the bonnet. Filling the diesel side at the petrol pump happens constantly. Far less regularly, the AdBlue side gets filled — normally from a bottle, by a person working out where it goes. The mistake grows in the gap between them. ## How does AdBlue in your diesel tank happen in Kellington? It's hardly ever carelessness. Three things tend to line up. Hurry comes from the warning. Your car warns you as AdBlue runs low, and a dry tank puts it into limp mode — so the top-up gets done quickly, before work on a driveway off Main Street, or heading home in the car park outside The Red Lion. Next, the hand reaches for the cap it would have used on the old vehicle — because a hire car, a new car or a company car puts the fillers where your last one did not. And the bottle fits. A bottle with a spout goes into a diesel filler as easily as an AdBlue one, and so nothing stops the tip after it has started. Beal or the heart of Kellington: it is the same few seconds in both. ## The AdBlue filler and the diesel filler: telling them apart Look at these first, on a forecourt in Kellington or a drive over in Kellingley. Seconds, that's all. - Where it sits misleads; the cap doesn't. AdBlue caps are often blue or bear the word "AdBlue" — diesel ones normally don't. - Check the size: the smaller neck is, on many cars, the AdBlue one. - A label inside the fuel flap frequently shows which fuel goes where, on plenty of motors. Look for it. - In your boot or under the bonnet: that's where your filler sits if it is not by the diesel cap, and the handbook says which. - The previous driver will know. Ask when you pick up a rental or fleet car — from Whitley Bridge's car park, perhaps — not once the warning comes on. ## How to top up without AdBlue in your diesel tank When the light comes on, wherever in North Yorkshire, follow this routine. - Not in a rush on the side of Eastfield Lane, not on a slope, not with your engine running: park then switch off properly. - Find the AdBlue filler, read the cap, and say the name "AdBlue" aloud while unscrewing it. It seems daft. It does the trick. - If both sit under one flap, check the diesel cap is still closed before you lift the bottle — then leave it on. - Using the bottle's own spout, tip slowly — and stop when it's full or the bottle is empty. - Before starting your car, shut the cap and check a second time that your diesel cap was never came off. Spot at step two or three that it's already gone into the diesel side? So stop just there. Don't carry on to step five. ## AdBlue in the diesel tank already, in Kellington? Brief order, then. First: your motor stays unstarted. Don't switch the ignition on; on plenty of diesels that alone runs the fuel pump. Filling up with diesel won't thin it: instead, AdBlue sinks to the bottom of the tank, right where fuel is taken from. If you are at a forecourt, whether it is the Morrisons or the Esso, ask the staff to help push your car away from the pump. At home in Kellington? Then the car stays where it is. Stop as soon as it is safe and switch off, if your motor has already run. Come off the M62 — under 3 miles out of Kellington — at the next junction.

Which liquid went in, the amount, and whether it ran: our technicians ask since the answers decide both work and price. You hear that quote on the phone, before anyone heads out. Emptying your tank comes next, followed by a thorough flush of the fuel system. AdBlue crystallises and is corrosive to some of the metals in a fuel system, so it doesn't wash out on its own — which is why that matters more with AdBlue than with petrol. The filter cleaned or, if it must be, replaced; fresh diesel in; then a check of your vehicle. We do not go until it has been started and is running properly. If the engine hasn't run, most jobs take about half an hour once we're there, using pumps that are safe on a working forecourt and quiet enough to use outside a house at night. Payment happens on the day, not upfront, and you receive the documents an insurer asks for: an engineer's report and a VAT invoice. Before we get there, have a look at your insurance documents; plenty carry cover for misfuelling. ## About Kellington and where it is Kellington is a small village in North Yorkshire, situated on the riverside at a low elevation of around 12 metres.
