Keep the engine and ignition off then call 0333 366 0103 now — the rest can wait if AdBlue is already in the diesel tank. Caught before your engine runs, it is generally a drain and a thorough flush, done where your car is in Stenton. The rest of this page covers why it takes place and how to ensure it doesn't — handy if you're reading before it has happened. ## AdBlue in a diesel car: two tanks, two fillers Diesel feeds your engine — yet many current diesels seen around Stenton and Eastfield hold a second liquid as well. AdBlue goes to your exhaust, where it is sprayed into the gas to fresh it, and it lives in a tank of its own. There is a filler for each tank. Many of cars have a single flap for both, whereas some move the AdBlue filler to your boot or under the bonnet. Diesel gets filled at every forecourt visit, again and again. A driver who has to stop and work out where it goes usually tops up the AdBlue side, from a bottle, and far less regularly. It is in that gap that the mistake happens. ## How does AdBlue in your diesel tank take place in Stenton? Seldom is it carelessness: usually three things coincide. To start with, the warning. Low AdBlue triggers a message from your car, and letting it run out leads to limp mode — hence a hurried top-up, perhaps before work off Foxton Drive, or at Foxton Bar & Grill on the way home after work. Next, your hand goes for the cap it knew on the old car — since a rental car, a new motor or a company car puts the fillers where your last one did not. Lastly, the spout fits: a diesel filler or AdBlue filler, it goes in just as easily, and once the tip begins, nothing halts it. It takes seconds, be it in Finglassie or bang in the heart of Stenton. ## Telling the AdBlue filler from your diesel filler Whether a Stenton forecourt or a drive over in Northend, spend a couple of seconds over these before any is poured in. - Colour and lettering: an AdBlue cap is often blue, or says "AdBlue", where a diesel cap normally does not. Trust the cap, not where it sits. - Many motors give AdBlue the smaller neck of the two. - Open the flap and look for a label — many cars show what goes in each filler just there. - In your boot or under the bonnet: that's where the filler sits if it's not by your diesel cap, and the handbook tells you which. - Picking up a hire or company car, say at the car park outside Glenrothes with Thornton? Check with whoever drove the vehicle last before you set off, rather than once the light comes on. ## Topping up AdBlue without it reaching the diesel tank A routine for the day the light comes on, wherever around Fife that is. - Park then switch off. Not on a slope, not with your engine running, and not in a rush on the side of Parbroath Road. - Find the AdBlue filler and read the cap. Say "AdBlue" out loud as you unscrew it. It sounds daft and it works. - The two behind one flap? So confirm the lid on the diesel side stays closed ahead of lifting the bottle. - Gently is best, through the bottle's own spout, until it's full or the bottle runs out. - Before you start the car, shut the cap and look a second time that your diesel cap never came off. Stop there if you find, at stage two or three, that you've already poured into the diesel side. Never carry on to stage five. ## AdBlue in your diesel tank already, in Stenton? Don't start your engine: that's where the short order of things begins. Leave the ignition off as well, since on many diesels it by itself runs the pump. Diluting it with extra diesel won't work, since AdBlue sinks to the bottom instead of blending — and that's where your fuel is pulled from. The attendants at BP, Shell or another forecourt will usually lend a hand pushing the vehicle away if asked. At home around Stenton? Then the vehicle remains where it is. Stop as soon as it is safe and switch off, if your motor has already run. Come off the M90 — under 10 miles out of Stenton — at the next junction. Distance counts — a quick hop across Stenton makes a smaller job than heading under 15 miles towards Dunfermline — so say about how far it went. ## Stenton: what occurs when our engineers get there Our engineers come to the vehicle wherever it has stopped, whether that is outside the local primary school, close to UFOs or on your own driveway. What fluid was put in, the quantity, and if it ran: our engineers ask because the answers set both work and quote. Nobody heads out before you have had the quote over the phone. After that: draining, then a thorough flush of the entire system. Much more than with petrol, it counts here: crystals build up, certain metals are attacked, and nothing clears out on its own, no matter how long it sits. After the fuel filter has been flushed — or replaced, if required — fresh diesel is added, and then your vehicle gets tested. Before leaving, our engineers fire it up and confirm that it's running smoothly. Most jobs are finished in about half an hour once our engineers arrive, as long as your motor hasn't run — and the pumps we use are fine on a busy forecourt yet quiet at night beside a house. Nothing in advance; you settle up that day. Afterwards, a VAT invoice and the report from the engineer go to you for your insurer. While we travel, have a look at your insurance documents; many include cover for misfuelling. ## About Stenton and where it is Stenton is a suburban area situated on the riverside in Fife, with a mix of terraced housing and a relatively low elevation of 67 metres.
