Then set this page down for now, keep your ignition and engine off, then call 0333 366 0103. Caught before your engine runs, it is normally a drain and a thorough flush, done where the car is in Appleby-in-Westmorland. The rest of this page explains why it takes place and how to make sure it does not — handy if you are reading before it has happened. ## AdBlue in a diesel motor: two tanks, two fillers Many newer diesels around Langton, as well as Appleby-in-Westmorland, run on two liquids; your engine gets only your diesel. AdBlue goes to the exhaust, where it is sprayed into the gas to fresh it, and it lives in a tank of its own. Every tank has a filler of its own. Some cars put the AdBlue filler in your boot or under the bonnet; plenty more have both together under one flap. The diesel side is fuelled at the petrol pump all the time. Much less commonly, the AdBlue side gets filled — normally from a bottle, by someone working out where it goes. It is in the gap that the error lives. ## Appleby-in-Westmorland: how AdBlue in the diesel tank occurs It's rarely carelessness. Three things tend to line up. Haste follows from the warning. The car tells you as AdBlue runs low, and an empty tank sends the vehicle into limp mode — so the top-up happens quickly, before work on a driveway off Low Wiend, or on the way home in the car park outside Crown & Cushion. The old car's filler is where your hand goes — yet a hire car, a new car or a company car keeps the fillers elsewhere. That's a second factor: an unfamiliar vehicle. No part halts the pour after it has started, because a bottle with a spout goes into a diesel filler as readily as an AdBlue one. The bottle fits. The same few seconds decide it, in the middle of Appleby-in-Westmorland or out in Colby. ## Which filler is for AdBlue, and which for diesel? Before you pour anything, whether on a drive in Crackenthorpe or a forecourt around Appleby-in-Westmorland, check these. They take a couple of seconds. - Blue and lettering: an AdBlue cap is frequently blue, or says "AdBlue", where a diesel cap normally does not. Go by the cap, not where it sits. - Plenty of motors give AdBlue the smaller neck of the two. - The flap. Look inside the fuel flap for a label. Many motors say there which fuel goes where. - In your boot or under the bonnet: that is where the filler sits if it's not by the diesel cap, and the handbook tells you which. - 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 Appleby. ## Keeping AdBlue out of your diesel tank when you top up The day the light comes on, anywhere across Cumbria, follow this routine. - Not in a rush on the side of Boroughgate, not on a slope, not with your engine running: park and switch off properly. - Locate the AdBlue filler, read the cap, and speak the name "AdBlue" aloud as you unscrew it. It sounds daft. It works. - The diesel cap stays on. Where both share a flap, make sure it's closed before lifting the bottle. - Pour slowly, using the bottle's own spout. Stop when it's full or when the bottle is empty. - Only then, start the vehicle: close the cap, check again, and make sure the diesel cap was never opened. Find during the second or third step that the bottle went in the diesel filler? That is where you stop. Never go on to step five. ## Appleby-in-Westmorland: already put AdBlue in your diesel tank? Don't start the engine: that is how the short order of things starts. Don't switch the ignition on; on plenty of diesels that alone runs the fuel pump. Filling up with diesel will not dilute it: instead, AdBlue drops to the bottom of that tank, right where the fuel is drawn from. Ask the staff to help push the vehicle away from the pump if you're at a forecourt — the the nearest petrol station, the Gulf or somewhere else. At home around Appleby-in-Westmorland? Then the car remains where it is. When the engine has run by now, pull over somewhere safe then turn the car off. On the M6, under 10 miles from Appleby-in-Westmorland, that means the next junction. A short hop across Appleby-in-Westmorland is a smaller job than a run towards Carlisle, under 50 miles away, and so tell us roughly how far it went. ## Our arrival around Appleby-in-Westmorland, and what occurs next Our technicians come to your car wherever it has stopped, whether that's outside Appleby Primary School, close to Low Cross or on your own drive. The answers decide the work and the price, so we ask what got in, about how much, and whether it has run. On the call itself, you hear our price — ahead of anything else. Next: a drain, then a thorough flush of the whole system. With AdBlue that counts 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. Testing comes at the end: before that, clean diesel goes in, and the fuel filter is flushed or replaced if necessary. Before leaving, we fire it up and make sure that it is running correctly. Most jobs are done in about half an hour once our engineers get there, provided your engine has not run — and the pumps our technicians use are safe on a busy forecourt yet quiet at night beside a house. You pay on the day, with nothing upfront, and get a VAT invoice and an engineer report for your insurer. Wrong-fuel cover is part of plenty of insurance policies — so use the wait to check yours. ## About Appleby-in-Westmorland, briefly Appleby-in-Westmorland is a town situated in the Eden Valley in Cumbria, with the River Eden running alongside.
