Then put this page aside for now, keep the ignition and engine off, then ring 0333 366 0103. A drain plus a thorough flush, done just where the vehicle stands around Heath End, is normally what it takes when caught before the motor runs. The rest of this page explains why it happens and how to ensure it does not — handy if you're reading ahead of time. ## Two fillers, two tanks: AdBlue in a diesel motor Many modern diesels in Bermuda, like those in Heath End, carry on two fluids; your motor gets just your diesel. AdBlue's own tank keeps it, and from there it is sent to your exhaust, where a spray cleans the gas. Each tank has its own filler. Under one flap, next to each other: that is the arrangement on many cars. On others, AdBlue's filler is beneath the bonnet or in the boot instead. Filling the diesel side at the petrol pump happens all the time. The AdBlue side is filled far less commonly, normally from a bottle, and normally by someone who has to stop and think where it goes. That gap is where the error lives. ## AdBlue in your diesel tank in Heath End: how it happens Carelessness rarely explains it. What does is three things lining up at once. First, the warning. Low AdBlue brings a message from the car, and running dry leads to limp mode — so a rushed top-up, perhaps before work off Tenlons Road, perhaps outside Hare & Hounds on the way home after work. Then the vehicle is strange. A hire car, a new vehicle or a company car puts the fillers where your last one did not, and the hand reaches for the cap it would have used on the old one. Third, the bottle goes in: diesel filler or AdBlue filler, it slides in just as readily, and once the pour starts, no part stops it. It's a few seconds, be it in Chilvers Coton or bang in the centre of Heath End. ## How to tell the AdBlue filler from the diesel one Before you tip anything, whether on a drive in Stockingford or a forecourt in Heath End, check these. They take a couple of seconds. - Position misleads; the cap does not. AdBlue ones are often blue or carry the word "AdBlue" — diesel ones normally don't. - Look at the size: the smaller filler neck is, on plenty of cars, the AdBlue one. - The flap. Look inside your fuel flap for a label. Many vehicles say there which fuel goes where. - In the boot or under the bonnet: that is where your filler is if it's not by your diesel cap, and the handbook tells you which. - Ask the person who drove it last — before you leave, not when the light comes on — when you collect a hire or company car from somewhere like the car park at Bermuda Park. ## AdBlue top-ups that never reach your diesel tank A routine for the day the light comes on, wherever in Warwickshire that is. - Not in a rush on the side of Bermuda Road, not on a slope, not with your motor running: park then switch off properly. - Say "AdBlue" out loud as you unscrew the cap, once finding the AdBlue filler and read it. Daft, perhaps, but it works. - Leave your diesel cap on. If both sit under one flap, check the diesel cap is still closed before you lift the bottle. - Stop when your tank is topped up or the bottle is empty; until then, pour gently through the own spout. - Shut the cap, then check once more — making sure the diesel filler stayed closed the whole time. Only then, start your car. Stop there if you find, at step two or three, that you've already poured into your diesel side. Skip step five altogether. ## Put AdBlue in the diesel tank around Heath End already? What follows is a short order of things, beginning with not starting your engine. On plenty of diesels your ignition alone runs the fuel pump, and so don't switch the vehicle on. Thinning it with extra diesel won't work, since AdBlue settles to the bottom rather than blending — and that is where the fuel is sucked from. Ask the staff to help roll your car away from the pump if you're on a forecourt — the JET, the another forecourt nearby or anywhere else. Your own drive in Heath End is the place it should stay. If the motor has already run, stop as soon as it is safe and switch off. Come off the M6 — under 5 miles out of Heath End — at the next exit. Mileage matters — a quick hop across Heath End makes a smaller job than heading under 10 miles towards Coventry — so say roughly how far it went. ## Our arrival around Heath End, and what occurs next Anywhere your car came to rest, whether outside Glendale Infant School, near Heath End Church or on your own drive, the van travels to it. What fluid went in, the amount, and whether it ran: we ask since the replies decide the work and price. That price comes over the phone, ahead of any van leaving. Then your tank is drained and the system rinsed thoroughly. Much more than with petrol, it matters with AdBlue: crystals form, certain metals are attacked, and nothing washes away on its own, no matter how long it is left. The filter is cleaned, or replaced where it needs to be; fresh diesel goes in; and your car is tested. The engine is started next and checked to confirm it runs correctly, all before our engineers head off. Using pumps safe on a busy forecourt and quiet enough to use outside a house at night, most jobs where the engine hasn't run need about half an hour once our engineers arrive. You pay on the day, with nothing upfront, and get a VAT invoice and an engineer report for your insurer. It is worth checking your insurance while we travel to you: misfuelling cover comes with plenty of policies. ## About Heath End and where it is Heath End is a suburban area in Warwickshire, situated lakeside with a mix of semi-detached housing and other residential properties.
