Caught before the motor runs, it is generally a drain and a thorough flush, done where the car is in Attercliffe Hill Top. Not happened yet? Below, the page explains the why it happens and the how to avoid it altogether. ## AdBlue in a diesel motor, and its separate tank Plenty of newer diesels around Attercliffe, like those in Attercliffe Hill Top, carry on two liquids; the motor gets only the diesel. Your exhaust, not your engine, is where AdBlue goes: dosed into the fumes to fresh them, from its own tank. There is a filler for every tank. On a lot of cars the two sit side by side under the same flap; on others the AdBlue filler is in the boot or under the bonnet. At the petrol pump, your diesel side is topped up all the time. Much less commonly, the AdBlue side is topped up — normally from a bottle, by someone thinking about where it goes. It's in that gap that the mistake happens. ## AdBlue in your diesel tank in Attercliffe Hill Top: how it occurs Three things tend to come together, and carelessness is seldom one of them. On a driveway off Attercliffe Common before work, or in the car park outside Noose and Gibbet Inn heading home: that is where the rushed top-up happens. Why the rush? As AdBlue gets low the car tells you, and once it is empty, limp mode kicks in. Unfamiliar vehicles come second, too. Rentals, new vehicles and company motors put their fillers differently, and the hand reaches for the cap used on the old one. A spouted bottle meets no resistance at a diesel filler any more than at an AdBlue one. And so the tip, once started, keeps on. It takes seconds, whether out in Greenland or bang in the centre of Attercliffe Hill Top. ## How to tell the AdBlue filler from the diesel one Be it a Attercliffe Hill Top forecourt or a driveway over in Darnall, spend a couple of seconds on these before anything goes in. - Check the cap rather than going by where it sits: AdBlue caps are frequently blue or marked "AdBlue", and diesel ones usually are not. - On many motors, size gives it away: AdBlue has the smaller filler neck. - The flap. Look inside the fuel flap for a label. Many cars say there which fuel goes where. - The handbook shows which it is when the filler is not next to your diesel cap: your boot, or under the bonnet. - Picking up a hire or company car, say at the car park at Meadowhall? Check with whoever drove it last before you set off, not once the light comes on. ## How to top up without AdBlue in your diesel tank On the day the warning appears — wherever you are around South Yorkshire — a simple routine to use. - Park and switch off. Not on a slope, not with the engine running, and not in a rush on the side of Amberley Street. - Say "AdBlue" out loud as you unscrew the cap, once you find the AdBlue filler and read it. Silly, yes, yet it does the trick. - The two under a single flap? Then make sure the lid on the diesel side stays 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 after that, start your car: close the cap, check once more, and make sure your diesel cap was never opened. If at step two or three you find you have already poured into your diesel side, stop there. Don't go on to step five. ## Attercliffe Hill Top: already put AdBlue in your diesel tank? Short order, then. First: the engine remains off. Keep the ignition off too, since on plenty of diesels it alone runs the pump. AdBlue does not mix with diesel — it sinks to the bottom of that tank, where the fuel is sucked from — so don't top up with diesel to thin it. The staff at Shell, BP or another forecourt will usually help to push the vehicle away when you ask. At home around Attercliffe Hill Top? Then your car stays put. If the engine has already run, stop as soon as it is safe and switch off. Leave the M1 — under 3 miles out of Attercliffe Hill Top — at the first exit. Mileage matters — a short hop across Attercliffe Hill Top is a smaller job than driving under 3 miles towards Sheffield — so tell us about how far it went. ## What happens when we turn up in Attercliffe Hill Top Our engineers come to the car wherever it has stopped, whether that's outside Phillimore Community Primary School, close to Utilita Arena Sheffield or on your own drive. Our engineers ask what got in, about how much, and whether it has run, since the replies settle the work and our price. Nobody sets off before you have had our quote by phone. Your system is then purged thoroughly, once that tank is emptied. More than with petrol, it matters with AdBlue: the crystals build up, certain metals are attacked, and nothing clears out unaided, no matter how long it is left. The filter is cleaned, or replaced where it needs to be; clean diesel goes in; and the vehicle is tested. After that our engineers start the car and check it runs correctly before we go. Unrun cars usually need a half-hour job after arrival. The equipment is fine on a busy forecourt, and quiet 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. While we travel, take a look at your insurance documents; plenty include cover for misfuelling. ## About Attercliffe Hill Top Attercliffe Hill Top is a suburban area in South Yorkshire, situated near the River Don and approximately 2.3 miles from Sheffield city centre.
