Then put this page aside for now, leave your ignition and motor off, then call 0333 366 0103. Caught before your motor runs, it's usually a drain and a thorough flush, done where the vehicle is around Annitsford. If you're reading before it has happened, the remainder of this page is about why it happens and how to make sure it does not. ## Two fillers, two tanks: AdBlue in a diesel vehicle No single liquid but two: that is what plenty of newer diesels near Annitsford and Dudley run, with diesel feeding your motor. The exhaust, not your engine, is where AdBlue goes: dosed into the gas to fresh it, from a separate tank. Each tank has its own filler. On a lot of motors the two sit side by side under the same flap; on others the AdBlue filler is in your boot or under the bonnet. The diesel side is filled at the petrol pump all the time. Much less commonly, the AdBlue side gets topped up — normally from a bottle, by someone working out where it goes. It is in that gap that the slip lives. ## Annitsford: how AdBlue in your diesel tank takes place Carelessness rarely causes it. Instead is three things lining up together. First, the warning. Low AdBlue brings a message from the car, and running dry leads to limp mode — so a hurried top-up, maybe before work off Broad Law, or at Willow Farm on the way home that evening. The old car's filler is where the hand reaches — yet a hire car, a new vehicle or a company car puts the fillers elsewhere. That's a second thing: an unfamiliar motor. Nothing stops the tip after it has started, since a bottle with a spout goes into a diesel filler as easily as an AdBlue one. The bottle fits. The same few seconds decide it, in the middle of Annitsford or out in Southfield Lea. ## How to tell the AdBlue filler from the diesel one Before you tip anything, whether on a drive in Collingwood Chase or a forecourt in Annitsford, check these. They take a few seconds. - The cap. The AdBlue cap is commonly blue, or marked "AdBlue". Your diesel cap usually isn't. Read it instead of going by position. - The size. On many vehicles the AdBlue filler neck is the smaller of the two. - A label inside the fuel flap often shows which fuel goes where, on plenty of cars. Look for it. - The handbook shows where it is if your filler isn't next to your diesel cap: your boot, or under the bonnet. - Ask the person who drove it last — before you leave, not when the light comes on — when you pick up a hire or company car from somewhere like the car park outside Cramlington. ## Keeping AdBlue out of the diesel tank when you top up A routine for the day the light comes on, wherever in Northumberland that is. - Turn off after you park — flat ground, engine off, and never in a rush by Silverton Court on the verge. - Silly as it sounds, speaking "AdBlue" aloud as you unscrew the cap works — once you've found your filler and read the cap. - The two under one flap? So confirm the lid on your diesel side stays shut ahead of raising the bottle. - Gently is best, through the bottle's own spout, till it's full or the bottle is empty. - Before starting the vehicle, shut the cap and check a second time that the diesel cap never came off. Find at stage two or three that it's already gone into the diesel side? Then stop right there. Don't go on to stage five. ## Annitsford: already put AdBlue in the diesel tank? Short list, then. First: the motor stays unstarted. Don't switch your ignition on; on plenty of diesels that alone runs the fuel pump. Thinning it with more diesel won't work, because AdBlue sinks to the bottom instead of mixing — and that is where your fuel is pulled from. Ask the staff to help roll your car away from the pump if you are on a forecourt — the Co-op Food, the BP or somewhere else. Your own driveway around Annitsford is the place it stays. Already started? Pull over once it is safe, then switch off. Annitsford sits under 10 miles from the A167(M); there, take the next exit. Roughly how far did it go? Hopping across Annitsford is smaller a job than a trip of under 10 miles towards Newcastle upon Tyne, and so say. ## When our technicians arrive in Annitsford, what happens? Anywhere your car came to rest, whether by Cragside CofE Controlled Primary School, beside St. John the Baptist or on your own drive, our van comes to it. The replies determine this work and our quote, and so our engineers ask what got in, about how much, and if it has run. You hear that price on the phone, before anybody sets off. The fuel system is then cleaned thoroughly, after that tank is drained. AdBlue crystallises and is corrosive to some of the metals in a fuel system, and so it doesn't wash out on its own — which is why the flush matters more with AdBlue than with petrol. Testing comes last: before that, clean diesel goes in, and the filter is flushed or replaced as needed. We don't go until it has been started and is running smoothly. Unstarted cars usually mean a half-hour visit after arrival. The kit is fine on a live forecourt, and hushed enough for a residential street late at night. You pay on the day, with nothing upfront, and get a VAT invoice and an engineer report for your insurer. It's worth checking your policy as the van travels to you: misfuelling cover is included with plenty of policies. ## About Annitsford Annitsford is a suburban area situated on the riverside in Northumberland, with an elevation of 52 metres and a mix of terraced housing.
