Then put this page aside a moment, leave the ignition and engine off, and call 0333 366 0103. Around Netherthorpe, finding it before the engine turns usually means a drain and a thorough flush where it stands. Nothing happened yet? Below, the page covers the reasons it occurs and the ways to avoid it for good. ## AdBlue in a diesel car, and its separate tank Plenty of newer diesels on the roads about Netherthorpe and Kelham Island carry two liquids, not one. Diesel goes to the motor. The exhaust, not the motor, is where AdBlue goes: dosed into the gas to fresh it, from its own tank. There is a filler on each tank. Under one flap, next to each other: that's the layout on a lot of vehicles. Elsewhere, AdBlue's filler is beneath the bonnet or in your boot instead. Filling your diesel side at the petrol pump goes on constantly. Rarely filled, AdBlue normally comes from a bottle, tipped by a driver who has to stop and think what cap to use. Mistakes happen in the gap between them. ## How AdBlue in your diesel tank takes place around Netherthorpe It's rarely carelessness. Three things tend to line up. The warning comes first. As AdBlue runs low the vehicle tells you, and if it runs out altogether, your vehicle drops into limp mode. So the top-up is done in a hurry: on a drive off Sudbury Street before work, or in the car park outside The Wellington on the way home. The old car's filler is where your hand goes — but a hire car, a new motor or a company car puts the fillers elsewhere. That is the second factor: a strange vehicle. Lastly, the spout fits: diesel filler or AdBlue one, it goes in just as easily, and after the pour begins, nothing stops it. Port Mahon or the heart of Netherthorpe: it takes the same few seconds in both. ## Telling the AdBlue filler from your diesel filler A few seconds is all these take — so run through them before you pour anything, on a drive in Neepsend or a forecourt in Netherthorpe. - The cap. The AdBlue cap is commonly blue, or marked "AdBlue". The diesel cap normally is not. Read it instead of going by where it sits. - Plenty of motors give AdBlue the smaller neck of the two. - Check inside the fuel flap: plenty of cars have a label there saying which fuel goes where. - The handbook shows which it lives when your filler isn't next to the diesel cap: your boot, or under the bonnet. - The previous driver knows. Check as you pick up a hire car or company car — from Sheffield's car park, say — rather than when the warning appears. ## Keeping AdBlue out of your diesel tank when you top up For the day the warning appears — anywhere you are in South Yorkshire — a routine to use. - Pull in somewhere level, motor off, with time in hand — not hurried on the side of Meadow Street. - Silly as it sounds, speaking "AdBlue" out loud as you unscrew the cap works — after you have found your filler and read it. - If both sit under one flap, check your diesel cap is still closed before you lift the bottle — then leave it on. - Slowly does it, through the bottle's own spout, until it's full or the bottle runs out. - Only then, start your car: close the cap, check once more, and make sure your diesel cap was never opened. If at stage two or three you find you have already poured into your diesel side, stop there. Stage five is out. ## AdBlue in your diesel tank already, in Netherthorpe? What follows is a short order of things, beginning with no starting your motor. On many diesels your ignition alone runs the fuel pump, and so do not switch the car on. AdBlue doesn't mix with diesel — it sinks to the bottom of the tank, where the fuel is drawn from — so do not top up with diesel to dilute it. On a forecourt — Shell, JET or another — the attendants will usually help push your car away, if you ask. Leave it where it is if you are on your own drive in Netherthorpe. Where your motor has been run by now, stop somewhere safe and switch the car off. Come off the Tinsley Viaduct — under 5 miles out of Netherthorpe — at the first exit. Mileage matters — a short hop across Netherthorpe is a smaller job than driving under a mile to Sheffield — so tell us roughly how far it went. ## When our technicians get there in Netherthorpe, what takes place? Anywhere the vehicle came to rest, whether by Netherthorpe Primary School, beside Masjid Risalah or on your own drive, our van comes to it. Both the work and our quote depend on three answers — what fluid, what amount, and whether it's run — so our technicians ask. On the call itself, you hear the price — ahead of anything else. The system is then flushed thoroughly, once that tank is cleared. Not like petrol, AdBlue leaves crystals and attacks some fuel-system metals, and neither clears out unaided. Hence it counts more. Once the fuel filter is cleaned — or replaced, if needed — fresh diesel goes in, and finally the vehicle is tested. We don't leave until it has been fired up and is running smoothly. Most jobs are done in about half an hour after our technicians arrive, provided the motor has not run — and the pumps we use are safe on a live forecourt and quiet at night outside a house. No money in advance; you settle up that day. Afterwards, a VAT invoice and the report from the engineer are handed to you for the insurer. It is worth looking at your policy as the van travels to you: misfuelling cover is included with many policies. ## About Netherthorpe, briefly Netherthorpe is a suburban area located on the riverside in South Yorkshire, with a mix of residential and commercial properties.
