A drain plus a full flush, carried out just where your car stands in Horse Close, is usually what it takes when found before the motor runs. If you are reading before it has happened, the remainder of this page is about why it occurs and how to make sure it does not. ## AdBlue in a diesel motor, and its separate tank Diesel goes to the motor — but many current diesels driven round Horse Close and Greatwood hold a second fluid too. Its own tank holds it, and from there it is sent to the exhaust, and there spraying cleans the fumes. Each tank has its own filler. Under one flap, side by side: that is the layout on a lot of cars. On others, AdBlue's filler sits beneath the bonnet or in the boot instead. Topping up your diesel side at the pump goes on all the time. Far less frequently, the AdBlue side is filled — mostly from a bottle, by someone thinking about where it goes. It is in that gap that the mistake happens. ## AdBlue in the diesel tank around Horse Close: how it happens Three things tend to line up, and carelessness is seldom one of them. Hurry follows from the warning. Your car warns you as AdBlue runs low, and a dry tank puts the vehicle into limp mode — so the top-up happens quickly, before work on a drive off Roughaw Road, or heading home in the car park outside The Craven Hotel. Then your car is new. A hire car, a new car or a company car puts the fillers where your last one didn't, and the hand gets to for the cap it would have used on the old one. No part halts the pour once it has started, because a bottle with a spout goes into a diesel filler as easily as an AdBlue one. The bottle fits. New Town or the heart of Horse Close: it takes the same few seconds in both. ## Which filler is for AdBlue, and which for diesel? Before you tip anything, whether on a drive in Middle Town or a forecourt in Horse Close, check these. They take a few seconds. - Blue and lettering: an AdBlue cap is often blue, or says "AdBlue", where a diesel cap normally doesn't. Trust the cap, not its position. - Look at the size: the smaller filler neck is, on many cars, the AdBlue one. - Lift the flap and look for a label — plenty of cars mark which belongs in each filler right there. - In the boot or under the bonnet: that is where the filler sits if it's not by your diesel cap, and the handbook tells you which. - Ask the person who drove it last — before you leave, not when the light comes on — when you collect a hire or company car from somewhere like the car park at Skipton. ## Keeping AdBlue out of your diesel tank when you top up Wherever in North Yorkshire the light comes on, here is a routine for that day. - Turn off once parked — level ground, motor off, and never in a rush by Rombalds Drive on the verge. - Find the AdBlue filler, read the cap, and say the name "AdBlue" aloud while unscrewing it. It sounds silly. It works. - Leave your diesel cap on. If both sit under one flap, check your diesel cap is still closed before you lift the bottle. - Tip slowly, using the bottle's own spout. Stop when it's full or when the bottle is empty. - Only after that, start your car: close the cap, check once more, and make sure the diesel cap was never opened. Spot at step two or three that it has already gone into the diesel side? Then stop right there. Don't go on to stage five. ## AdBlue in your diesel tank already, around Horse Close? Then the order of things is short. Don't start your engine. Don't switch the ignition on; on plenty of diesels that alone runs the fuel pump. Do not top up with diesel to thin it: AdBlue doesn't mix with diesel, it sinks to the bottom of the tank, where the fuel is sucked from. Ask the staff to help roll the car away from the pump if you are on a forecourt — the Tesco, the Morrisons or somewhere else. On your own drive in Horse Close? Then the car stays put. If your engine has already run, stop as soon as it is safe and switch off. The next junction means the place to come off if you are on the M65, under 10 miles from Horse Close. Roughly how far did it go? Hopping across Horse Close is less work than a run of under 25 miles to Bradford, so say. ## Our arrival around Horse Close, and what occurs next We come to the vehicle wherever it has stopped, whether that is outside Greatwood Community Primary School, near Great Wood Lathe or on your own driveway. Which liquid went in, the quantity, and if it ran: our technicians ask because those answers decide the work and quote. You hear that quote on the phone, before anybody heads out. The fuel system is then rinsed thoroughly, once that tank is emptied. AdBlue crystallises and is corrosive to some of the metals in a fuel system, and so it does not wash out on its own — which is why the flush matters more here than with petrol. A test comes at the end: before that, clean diesel goes in, and the fuel filter is flushed or replaced if necessary. We don't go until it has been fired up and is running smoothly. Unrun vehicles mostly need a half-hour job from the moment we arrive. The kit is fine on a live filling station, and quiet enough for a residential street after dark. The insurer will ask for the engineer's report and your VAT invoice, and you get both once this job is done. Payment is on the day, with no money upfront. Misfuelling cover is part of many insurance policies — so use the wait to check yours. ## About Horse Close and where it is Horse Close is a suburban area situated on the lakeside in North Yorkshire, with a mix of terraced housing and a population of around 4272 residents.
