In that case set this page aside for now, leave your ignition and motor off, and call 0333 366 0103. A drain and a full flush, carried out right where the car sits around Eastbourne, is usually what it needs when caught before your motor runs. The remainder of this page covers why it happens and how to ensure it does not — useful if you're reading ahead of time. ## AdBlue in a diesel car, and its separate tank Many modern diesels around Red Hall, like those in Eastbourne, carry on two fluids; your motor gets just the diesel. Kept in a tank of its own, AdBlue is fed into your exhaust stream and cleans it. There's a filler for every tank. Under one flap, side by side: that is the arrangement on a lot of motors. On others, AdBlue's filler sits beneath the bonnet or in the boot instead. The diesel side is fuelled at the pump all the time. A driver who has to stop and work out where it goes usually tops up the AdBlue side, from a bottle, and far less often. Mistakes happen in the gap between the two. ## How does AdBlue in the diesel tank take place around Eastbourne? Rarely is it carelessness: usually three things line up. Hurry follows from the warning. The car tells you as AdBlue runs low, and a dry tank puts the vehicle into limp mode — so the top-up gets done quickly, before work on a drive off Yarm Road, or on the way home in the car park outside The Wheatsheaf. The old car's cap is where the hand reaches — yet a rental car, a new vehicle or a company car keeps the fillers elsewhere. That is a second factor: a strange car. And the bottle fits. A bottle with a spout goes into a diesel filler as easily as an AdBlue one, and so nothing stops the pour after it has started. It takes seconds, be it in Firth Moor or bang in the heart of Eastbourne. ## Telling the AdBlue filler from your diesel filler Look at these first, at a forecourt in Eastbourne or a drive over in Darlington. A few seconds, no more. - Where it sits misleads; the cap doesn't. AdBlue ones tend to be blue or bear the name "AdBlue" — diesel ones usually do not. - Check the size: the smaller neck is, on plenty of cars, the AdBlue one. - Look inside your fuel flap: plenty of vehicles carry a label there showing which fuel goes where. - In the boot or under the bonnet: that is where the filler is if it's not by the diesel cap, and the handbook says which. - Picking up a hire or company car, say at the car park at Darlington? Ask the person who drove it last before you set off, not once the light comes on. ## How to top up without AdBlue in the diesel tank When the light comes on, anywhere across Durham, use this routine. - Turn off once parked — level ground, motor off, and never rushed beside The Stray at the roadside. - Say "AdBlue" out loud as you unscrew the cap, once you find the AdBlue filler and reading it. Silly, yes, yet it does the trick. - Leave your diesel cap on. If both sit under one flap, check your diesel cap is still closed before you lift the bottle. - Using the bottle's own spout, pour slowly — and stop when it is full or the bottle is empty. - Only then, start your car: close the cap, check a second time, and make sure the diesel cap was never opened. Stop there if you find, at stage two or three, that you have already poured into the diesel side. Don't go on to step five. ## Already put AdBlue in the diesel tank in Eastbourne? The short order of things, beginning with not starting your engine. Don't switch the ignition on; on plenty of diesels that alone runs the fuel pump. Thinning it with extra diesel fails, because AdBlue settles to the bottom instead of mixing — and that's where the fuel is sucked from. The staff at Shell, Sainsbury's or any forecourt will usually help pushing your car away when you ask. Your own driveway in Eastbourne is the place it should stay. If the engine has already run, stop as soon as it is safe and switch off. Come off the A66(M) — under 3 miles out of Eastbourne — at the first exit. Distance matters — a short hop across Eastbourne is a smaller job than heading under 25 miles to Durham — so tell us roughly how far it went. ## What happens when our engineers get there around Eastbourne Wherever the car has stopped, whether outside Heathfield Primary School, beside Eastbourne Sports Complex or on your own drive, the van comes to it. Both the work and our price rest on three answers — what liquid, what amount, and whether it has run — so we ask. You get that price on the phone, before anyone sets off. Emptying that tank comes next, then a thorough flush of your system. More than with petrol, it counts with AdBlue: crystals build up, certain metals are attacked, and nothing clears out on its own, no matter how long it sits. The filter cleaned or, if needed, swapped; fresh diesel in; and then a test of the car. We do not go until it has been started and is running properly. With pumps safe on a working forecourt and quiet enough to use outside a house at night, most jobs in which your motor has not run take roughly half an hour after our technicians are there. Your insurer will ask for an engineer's report and your VAT invoice, and you get both at the end. Payment comes on the day, with no money upfront. Misfuelling cover is part of plenty of insurance policies — and so use the wait to check yours. ## About Eastbourne Eastbourne is a suburban area in County Durham, situated inland at an elevation of 51 metres, with semi-detached housing being the predominant type of accommodation.
