In that case set this page aside a moment, keep your ignition and motor off, then phone 0333 366 0103. Around Rushey Mead, catching it before your motor runs normally means draining and a full flush where it stands. If you're reading before it has happened, the rest of this page is about why it happens and how to make sure it does not. ## Why does AdBlue in a diesel motor need its own filler? Not one fluid but two: that is how plenty of modern diesels around Rushey Mead and Humberstone run, with diesel for the motor. Its own tank holds it, and from there it is sent to your exhaust, where spraying treats the fumes. There's a filler on every tank. Under one flap, next to each other: that's the arrangement on a lot of vehicles. On others, AdBlue's filler is under the bonnet or in the boot instead. Topping up your diesel side at the petrol pump goes on constantly. The AdBlue side is topped up far less regularly, normally from a bottle, and usually by a person who has to stop and think where it goes. That gap is where the slip lives. ## Rushey Mead: how AdBlue in the diesel tank occurs It is seldom carelessness. Three things tend to line up. Haste follows from the warning. The vehicle warns you as AdBlue runs low, and an empty tank sends the vehicle into limp mode — so the top-up gets done quickly, before work on a drive off Kincraig Road, or on the way home in the car park at The Royal. Next, the hand goes for the cap it would have used on the old vehicle — since a hire car, a new motor or a company car puts the fillers where your last one didn't. And the bottle fits. A bottle with a spout goes into a diesel filler as easily as an AdBlue one, so nothing stops the pour once it has started. Whether it takes place in Belgrave or the middle of Rushey Mead, it's the same few seconds. ## How to tell the AdBlue filler from the diesel one Before you pour anything, whether on a drive in Mowmacre Hill or a forecourt in Rushey Mead, check these. They take a few seconds. - Read the cap instead of going by position: AdBlue caps are frequently blue or marked "AdBlue", and diesel caps normally aren't. - Check the size: the smaller filler neck is, on many cars, the AdBlue one. - The flap. Look inside your fuel flap for a label. Plenty of vehicles say there which fuel goes where. - Can't see it beside the diesel inlet? In that case check beneath the bonnet or in the boot — the handbook will say where. - 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 Syston. ## How to top up without AdBlue in your diesel tank A routine for the day the light comes on, wherever across Leicestershire that is. - Park and switch off. Not on a slope, not with your engine running, and not in a rush on the side of Birsmore Avenue. - Say "AdBlue" out loud as you unscrew the cap, after you find the AdBlue filler and read it. Daft, yes, yet it works. - Both under one flap? So confirm the cap on the diesel filler stays shut ahead of lifting the bottle. - Using the bottle's own spout, pour slowly — and stop when it is full or the bottle is empty. - Only after that, start the vehicle: close the cap, check a second time, 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. Step five is off limits. ## AdBlue in the diesel tank already, around Rushey Mead? Do not start your motor: that is how the short order of things starts. The fuel pump starts on many diesels the moment your ignition goes on — and so leave it off. AdBlue doesn't mix with diesel — it sinks to the bottom of the tank, where the fuel is sucked from — so do not top up with diesel to thin it. The attendants at Sainsbury's, Shell or another forecourt will usually help to push the vehicle away if asked. Your own driveway in Rushey Mead is the place it stays. If the motor has already run, stop as soon as it is safe and switch off. Rushey Mead sits under 10 miles from the M1; there, take the first exit. About how far did it go? Crossing Rushey Mead is smaller work than a run of under 3 miles to Leicester, and so say. ## When our technicians turn up around Rushey Mead, what takes place? Wherever your car came to rest, be it by Herrick Primary School, near Rushey Mead Library or at home, our van comes to it. The answers settle the work and the price, so our engineers ask what got in, about how much, and if it's run. You hear that quote by phone, before anyone heads out. The fuel system is then cleaned thoroughly, after that tank is drained. AdBlue crystallises and is corrosive to some of the metals in a fuel system, so it does not wash out on its own — which is why that counts more here than with petrol. A test is at the end: before that, clean diesel is added, and your filter is cleaned or replaced as needed. Before we leave, our engineers start the engine and check that it's running correctly. Most jobs are finished in about half an hour once our technicians get there, provided the motor has not run — and the pumps our technicians use are safe on a live forecourt and quiet at night outside a house. Paying happens on the day, not upfront, and you receive the paperwork your insurer wants: an engineer report and a VAT invoice. Many insurance policies include misfuelling cover, so it's worth checking yours while we're on the way. ## About Rushey Mead Rushey Mead is a suburban area located on the outskirts of Leicester, situated near the River Soar in Leicestershire.
