AdBlue already in the diesel tank? In that case set this page down a moment, leave the ignition and engine off, and phone 0333 366 0103. Normally, if the motor has not turned, it is drained and thoroughly flushed where the car sits in Howden Clough. Not happened yet? Further down, the page covers the reasons it takes place and the ways to avoid it for good. ## Why does AdBlue in a diesel car need its own filler? Diesel goes to your engine — but plenty of current diesels seen around Howden Clough and Upper Batley carry a second fluid too. AdBlue goes to your exhaust, where it is sprayed into the gas to clean it, and it lives in a tank of its own. There is a filler on each tank. Plenty of motors have a single flap for both, while others put the AdBlue filler to your boot or under the bonnet. Diesel gets filled on each filling station call-out, week in, week out. Someone who has to stop and work out where it goes normally fills the AdBlue side, from a bottle, and much less commonly. It's in that gap that the mistake lives. ## Howden Clough: how AdBlue in your diesel tank happens 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 an empty tank sends the vehicle into limp mode — so the top-up gets done in a rush, before work on a driveway off Risedale Close, or heading home in the car park at The Pheasant. Then the car is unfamiliar. A hire car, a new vehicle or a company car puts the fillers where your last one didn't, and your hand hits for the cap it would have used on the old one. A spouted bottle finds no resistance at a diesel filler any more than at an AdBlue one. And so the tip, once started, keeps on. It's a few seconds, whether out in Copley Hill or bang in the heart of Howden Clough. ## Which filler is for AdBlue, and which for diesel? Before you pour anything, whether on a driveway in Brown Hill or a forecourt around Howden Clough, check these. They take a couple of seconds. - Blue and lettering: an AdBlue cap is commonly blue, or says "AdBlue", where a diesel cap normally does not. Trust the cap, not its position. - The size. On plenty of cars the AdBlue filler neck is the smaller of the two. - A label inside your fuel flap frequently says which fuel goes where, on plenty of cars. Look for it. - The handbook shows which it lives when the filler isn't next to the diesel cap: the boot, or under the bonnet. - The person who drove the car last. On a hire or company car collected from somewhere like the car park outside Batley, ask before you leave, not when the light comes on. ## How to top up without AdBlue in your diesel tank The day the light comes on, wherever around West Yorkshire, use this routine. - Switch off once parked — level ground, engine off, and never in a rush by Birkby Brow Crescent on the verge. - Find the AdBlue filler and read the cap. Say "AdBlue" out loud as you unscrew it. It sounds silly and it works. - If both sit under one flap, check your diesel cap is still closed before you lift the bottle — and leave it on. - Stop once the tank fills or the bottle runs dry; until then, tip slowly using its own spout. - Close the cap and check a second time. Make sure your diesel cap was never opened. Only then start your car. If at stage two or three you find you have already poured into your diesel side, stop there. Never go on to step five. ## AdBlue in your diesel tank already, around Howden Clough? What follows is a short order of things, beginning with not starting the engine. Do not switch the ignition on; on plenty of diesels that alone runs the fuel pump. Topping up with diesel won't weaken it: instead, AdBlue sinks to the bottom of the tank, right where the fuel is taken from. The staff at the nearest petrol station, Shell or any forecourt will normally help pushing your car away when you ask. If you are on your own driveway in Howden Clough, leave it where it sits.

Wherever your car came to rest, whether by Windmill CofE (VC) Primary School, near Motorcycle Activity Centre or at home, our van travels to it. Our engineers ask what got in, about how much, and if it has run, because those replies determine the work and the quote. You hear that price on the phone, before anybody sets off. Your system is then purged thoroughly, once that tank is cleared. More than with petrol, it counts with AdBlue: crystals form, certain metals corrode, and nothing clears out on its own, no matter how long it is left. The filter is flushed, or replaced where it needs to be; fresh diesel goes in; and the vehicle is tested. The motor is started next and checked to confirm it runs smoothly, all before our engineers head off. Most jobs are done in about half an hour once we arrive, provided the motor hasn't run — and the pumps our technicians use are safe on a busy forecourt yet quiet after dark beside a house. No money upfront; you settle up on the day. At the end, a VAT invoice and the report from the engineer are handed to you for the insurer. While we travel, take a look at your insurance documents; many include cover for misfuelling. ## About Howden Clough and where it is Howden Clough is a suburban area in West Yorkshire, situated near the River Aire and close to the city of Leeds.
