In North Walbottle, finding it before your motor runs normally leaves a drain and a full flush where it stands. 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. ## Two fillers, two tanks: AdBlue in a diesel motor Plenty of current diesels on the roads round North Walbottle and Throckley carry two liquids, not one. Diesel goes to your engine. 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 for each tank. Under one flap, side by side: that's the layout on many cars. On others, AdBlue's filler is beneath the bonnet or in your boot instead. The diesel side is topped up at the pump all the time. Seldom filled, AdBlue usually comes from a bottle, poured by someone who has to stop and think what filler it needs. That gap is where the slip lives. ## How does AdBlue in the diesel tank occur around North Walbottle? Carelessness rarely causes it. Instead is three things coming up at once. Hurry follows from the warning. The vehicle warns you as AdBlue runs low, and a dry tank sends the vehicle into limp mode — so the top-up happens in a rush, before work on a driveway off Alcroft Close, or on the way home in the car park at The Chapel Park. Then, your hand reaches for the cap it would have used on the old vehicle — because a hire car, a new car or a company car places the fillers where your last one didn't. And the bottle fits. A bottle with a spout goes into a diesel filler as easily as an AdBlue one, so nothing stops the tip after it has started. Callerton or the middle of North Walbottle: it is the same few seconds either way. ## How to tell the AdBlue filler from the diesel one A few seconds is all the checks take — so run through them before you pour anything, on a drive in Callerton Lane End or a forecourt in North Walbottle. - The cap. The AdBlue cap is often blue, or marked "AdBlue". The diesel cap usually is not. Read it rather than going by where it sits. - Look at the size: the smaller filler neck is, on plenty of motors, the AdBlue one. - Check inside the fuel flap: plenty of motors have a label there saying which fuel goes where. - The handbook. If your filler isn't by the diesel cap, it's in your boot or under the bonnet, and the handbook says which. - Check with 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 outside Blaydon. ## How to top up without AdBlue in the diesel tank When the light goes on, wherever around Tyne and Wear, use this routine. - Switch off once parked — level ground, engine off, and not in a rush by Abbey Drive at the roadside. - Locate the AdBlue filler, read the cap, and speak the name "AdBlue" out loud as unscrewing it. It sounds silly. It does the trick. - Both behind a single flap? So make sure the lid on the diesel side stays closed before lifting the bottle. - Using the bottle's own spout, tip slowly — and stop when it is full or the bottle is empty. - Close the cap, then look again — confirm your diesel filler remained shut throughout. After that, start your car. Stop there if you find, at step two or three, that you've already poured into the diesel side. Skip stage five entirely. ## Already put AdBlue in the diesel tank around North Walbottle? Short order, then. First: the motor stays unstarted. The fuel pump runs on many diesels as soon as the ignition goes on — and so keep it off. Filling up with diesel won't thin it: instead, AdBlue drops to the bottom of that tank, just where the fuel is drawn from. The staff at Gulf, Esso or any forecourt will usually help to push the vehicle away when you ask. Your own driveway in North Walbottle is the place it should stay. Stop as soon as it is safe and switch off, if your motor has already run. The next junction is where to come off if you're on the Central Motorway East, under 5 miles from North Walbottle. Mileage matters — a quick hop across North Walbottle is a smaller job than heading under 5 miles towards Newcastle upon Tyne — so say about how far it went. ## North Walbottle: what takes place when we get there Our van comes to your car wherever it stopped — your own driveway, near Church of the Holy Nativity, or by Milecastle Primary School. Both the work and the price rest on three replies — which fluid, which amount, and if it has run — so our engineers ask. You get that price by phone, before anyone sets off. Then that tank is drained and the system flushed thoroughly. With AdBlue that matters more than with petrol: it crystallises and is corrosive to some of the metals in a fuel system, so it doesn't wash out on its own. The fuel filter is flushed, or replaced where it needs to be; clean diesel goes in; and the car is tested. Before leaving, we start the engine and make sure that it is running correctly. Unrun vehicles usually mean a half-hour visit after arrival. The equipment is fine on a busy filling station, and hushed enough for a residential street after dark. You pay on the day, with nothing upfront, and get a VAT invoice and an engineer report for your insurer. Many insurance policies include misfuelling cover, so it is worth checking yours whilst we're on the way. ## About North Walbottle itself North Walbottle is a locality situated inland in Tyne and Wear, approximately 4.9 miles from Newcastle upon Tyne.
