Caught before your motor runs, it is usually a drain and a thorough flush, done where your car is around Kirkby Stephen. Not happened yet? Below, the rest of the page covers the reasons it occurs and the how to avoid it for good. ## AdBlue in a diesel car, and its separate tank Plenty of modern diesels on the roads around Kirkby Stephen and Waitby carry two liquids, not one. Diesel goes to your engine. AdBlue goes to your exhaust, where it is sprayed into the gas to fresh it, and it lives in a tank of its own. Separate tanks, different fillers. Plenty of vehicles have a single flap for the two, whereas some put the AdBlue filler to the boot or under the bonnet. At the pump, the diesel side is topped up constantly. Someone who has to stop and think where it goes usually tops up the AdBlue side, from a bottle, and much less regularly. The mistake grows in that gap between the two. ## Kirkby Stephen: how AdBlue in your diesel tank occurs Rarely is it carelessness: normally three things coincide. First, the warning. Low AdBlue triggers a warning from your car, and running dry leads to limp mode — so a rushed top-up, perhaps before work off A685, or at Old Forge Micropub on the way home that evening. Unfamiliar vehicles come second, too. Hire cars, new cars and company cars put their fillers differently, and the hand goes for the cap used on the old one. Nothing halts the pour after it has started, since a bottle with a spout goes into a diesel filler as easily as an AdBlue one. The bottle fits. It takes a few seconds, whether out in Hartley or right in the centre of Kirkby Stephen. ## Telling the AdBlue filler from the diesel filler Check these first, on a forecourt in Kirkby Stephen or a driveway out in Soulby. A few seconds, that's all. - Position can mislead; the cap does not. AdBlue ones are often blue or bear the name "AdBlue" — diesel caps usually don't. - On many cars, size gives it away: AdBlue has the smaller filler neck. - The flap. Look inside the fuel flap for a label. Plenty of cars say there which fuel goes where. - Can't see it beside the diesel filler? Then check below the bonnet or in the boot — the owner's manual says which. - The previous driver will know. Ask as you pick up a hire car or company car — at the nearest station's car park, perhaps — rather than when the light appears. ## AdBlue top-ups that never reach the diesel tank Wherever in Cumbria the light comes on, here is a routine for the day. - Not in a rush on the side of Silver Street, not on a slope, not with the engine running: park then switch off properly. - Say "AdBlue" out loud as you unscrew the cap, after finding the AdBlue filler and read it. Daft, perhaps, but it does the trick. - The diesel cap stays on. Where both sit under a flap, make sure it's closed before the bottle comes up. - Stop once the tank fills or the bottle runs dry; until then, pour slowly using its built-in spout. - Close the cap, and check once more — making sure the diesel filler stayed shut throughout. Only then, start the vehicle. Stop there if you find, at step two or three, that you've already poured into the diesel side. Don't go on to step five. ## AdBlue in your diesel tank already, around Kirkby Stephen? Do not start the engine: that is where the short order of things begins. Leave the ignition off as well, because on many diesels switching it on by itself starts your pump. Don't top up with diesel to dilute it: AdBlue doesn't mix with diesel, it sinks to the bottom of the tank, where your fuel is drawn from. If you are at a forecourt, whether it is the Total Energies or the Shell, ask the attendants to help push the vehicle away from the petrol pump. Leave it where it is if you're on your own drive around Kirkby Stephen. Already run? Stop once it is sensible, then turn off. On the M6, under 15 miles from Kirkby Stephen, that means the next exit.

The replies settle the work and the price, and so our technicians ask what went in, about how much, and whether it has run. You get that quote on the phone, before anybody sets off. Emptying the tank comes next, then a thorough flush of your system. 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 that counts more here than with petrol. Once the filter is flushed — or renewed, if needed — fresh diesel is added, and then the car is tested. Before leaving, our technicians fire it up and check that it is running smoothly. Most jobs are finished in roughly half an hour once we arrive, provided your motor hasn't run — and the pumps we use are fine on a live forecourt yet quiet at night outside a house. Paying is on the day, not upfront, and you receive the documents an insurer wants: an engineer's report and a VAT invoice. It's worth looking at your insurance as the van travels to you: misfuelling cover comes with plenty of policies. ## About Kirkby Stephen itself Kirkby Stephen is a small town in Cumbria, situated on the River Eden at an elevation of 174 metres.
