In Harlow Hill, catching it before the engine runs normally means a drain and a full flush on the spot. Nothing happened yet? Further down, the rest of the page covers the why it happens and the how to avoid it for good. ## AdBlue in a diesel vehicle: two tanks, two fillers Plenty of current diesels on the roads about Harlow Hill and Beckwith carry two liquids, not one. Diesel goes to the motor. AdBlue's own tank keeps it, and from there it goes to your exhaust, and there spraying cleans the gas. Each tank has its own filler. Under one flap, next to each other: that is the layout on a lot of cars. Elsewhere, AdBlue's filler is beneath the bonnet or in the boot instead. The diesel side is topped up at the pump all the time. Seldom filled, AdBlue usually comes from a bottle, poured by a driver who must stop and think which cap it needs. The mistake grows in the gap between them. ## How does AdBlue in your diesel tank occur around Harlow Hill? Seldom is it carelessness: normally three things coincide. On a driveway off Plantation Road before work, or in the car park at The Shepherds Dog heading home: that is where the hurried top-up takes place. What is the reason for the rush? As AdBlue gets low the vehicle warns you, and once it is empty, limp mode follows. Unfamiliar cars come second, as well. Hire cars, new cars and company cars place their fillers in new places, and habit reaches for the cap used on the old one. A spouted bottle finds no resistance at a diesel filler no more than at an AdBlue one. And so the pour, once started, carries on. Harlow Carr or the heart of Harlow Hill: it is the same few seconds in both. ## The AdBlue filler and the diesel filler: telling them apart Be it a Harlow Hill forecourt or a driveway out in Oakdale, spend a few seconds over these before any is poured in. - Where it sits misleads; the cap doesn't. AdBlue ones tend to be blue or carry the word "AdBlue" — diesel caps usually don't. - On plenty of motors, the size tells: AdBlue has the smaller filler neck. - Look inside the fuel flap: plenty of motors carry a label there saying which fuel goes where. - In your boot or under the bonnet: that is where your filler sits if it is not by your diesel cap, and the handbook tells you which. - The person who drove it last. On a hire or company car picked up from somewhere like the car park at Harrogate, ask before you leave, not when the light comes on. ## AdBlue top-ups that never reach the diesel tank On the day the warning appears — anywhere it is in North Yorkshire — a routine to use. - Pull in somewhere level, engine off, with time in hand — never hurried on the side of Pinewood Gate. - Say "AdBlue" out loud as you unscrew the cap, after finding the AdBlue filler and read it. Silly, perhaps, yet it does the trick. - The diesel cap stays on. When both share a flap, confirm it's closed before the bottle comes up. - Tip slowly, using the bottle's own spout. Stop when it is full or when the bottle is empty. - Close the cap and check once more. Make sure your diesel cap was never opened. Only then start the vehicle. Stop there if you find, at stage two or three, that you've already poured into the diesel side. Don't go on to stage five. ## Put AdBlue in the diesel tank around Harlow Hill already? Do not start the motor: that is where the short order of things starts. Don't switch the ignition on; on plenty of diesels that alone runs the fuel pump. Thinning it with more diesel won't work, because AdBlue settles to the bottom instead of mixing — and that is where your fuel is pulled from. Ask the staff to help push your car clear of the pump if you're at a forecourt — the Asda, the Shell or anywhere else. If you are on your own driveway in Harlow Hill, leave it where it is. Stop as soon as it is safe and switch off, if your motor has already run. The next exit means the place to leave when you're on the A1(M), under 10 miles from Harlow Hill.

What liquid went in, the quantity, and whether it ran: our technicians ask because those answers decide the work and quote. On the phone call itself, you hear our quote — before anything else. Your system is then rinsed thoroughly, after the tank is drained. Unlike petrol, AdBlue forms crystals and eats at certain fuel-system metals, and none of it clears away by itself. Hence it matters more. A test comes last: before that, fresh diesel is added, and your filter is flushed or changed if necessary. Then we fire it up and confirm it runs correctly before we go. With pumps safe on a busy forecourt and quiet enough for use outside a house at night, most jobs where the motor has not run need roughly half an hour after our engineers arrive. The insurer usually wants the engineer's report and your VAT invoice, and you get both at the end. Payment is on the day, with no deposit. It's worth looking at your policy as the van travels to you: misfuelling cover is included with many policies. ## About Harlow Hill and where it is Harlow Hill is a suburban area in North Yorkshire, situated inland at an elevation of 181 metres, with semi-detached housing being the predominant type of accommodation.
