Then put this page down for now, leave your ignition and engine off, and ring 0333 366 0103. A drain and a full flush, carried out just where the vehicle stands in Brixington, is normally what it takes when caught before your engine runs. If you are reading before it has happened, the remainder of this page is about why it happens and how to make sure it does not. ## Two fillers, two tanks: AdBlue in a diesel motor Many newer diesels on the roads around Brixington and Exmouth carry two liquids, not one. Diesel goes to the engine. Kept in a tank of its own, AdBlue is sprayed into the exhaust stream to clean it. Every tank has one filler of its own. Plenty of cars share a single flap for both, while others put the AdBlue filler to your boot or under the bonnet. Diesel gets filled at each filling station visit, week in, week out. The AdBlue side is filled far less often, normally from a bottle, and normally by a person who has to stop and think where it goes. That gap is where the mistake lives. ## How does AdBlue in your diesel tank occur in Brixington? Seldom is it carelessness: normally three things line up. Haste follows from the warning. The car warns you as AdBlue runs low, and a dry tank sends it into limp mode — so the top-up gets done quickly, before work on a drive off Pines Road, or heading home in the car park at The Farmhouse. Then the vehicle is strange. A hire car, a new car or a company car puts the fillers where your last one did not, and your hand reaches for the cap it would have used on the old one. A spout-topped bottle finds no obstacle at a diesel filler no more than at an AdBlue one. So the pour, after begun, keeps on. It takes seconds, whether out in Hulham or bang in the heart of Brixington. ## The AdBlue filler and the diesel filler: telling them apart Whether a Brixington forecourt or a driveway over in Lympstone, spend a couple of seconds on these before anything goes in. - Position can mislead; the cap does not. AdBlue ones are often blue or bear the word "AdBlue" — diesel ones usually do not. - On plenty of motors, size gives it away: AdBlue has the smaller filler neck. - Lift the flap and check for a label — many cars mark which belongs in each filler just there. - Can't find it next to the diesel filler? In that case check below the bonnet or inside the boot — the owner's manual will say which. - The person who drove the car last. On a hire or company car picked up from somewhere like the car park outside Exmouth, ask before you leave, not when the light comes on. ## Keeping AdBlue out of your diesel tank when you top up The day the light comes on, wherever in Devon, use this routine. - Pull in on level, engine off, with time to spare — not hurried on the side of Brixington Lane. - Say "AdBlue" out loud as you unscrew the cap, after you find the AdBlue filler and reading it. Silly, yes, but it does the trick. - If both sit under one flap, check the diesel cap is still closed before you lift the bottle — then leave the car on. - Slowly does it, through the bottle's own spout, till it is full or the bottle runs out. - Close the cap and check again. Make sure the diesel cap was never opened. Only then start the vehicle. Spot at step two or three that it's already gone into your diesel side? So stop just there. Stage five is off limits. ## Already put AdBlue in your diesel tank around Brixington? The short order of things, beginning with not starting your engine. The fuel pump runs on many diesels as soon as the ignition is switched on — so leave it off. Topping up with diesel won't thin it: rather than mixing, AdBlue drops to the base of your tank, just where the fuel is taken from. At a forecourt — Tesco, Esso or any other — the attendants will normally help roll your car clear, when you ask. Your own drive in Brixington is the place it stays. Already started? Pull over once it is sensible, then switch off. Leave the M5 — under 10 miles out of Brixington — at the next junction. About how far did it go? Crossing Brixington is less a job than a trip of under 10 miles to Exeter, and so say. ## Our arrival around Brixington, and what takes place next Our engineers come to your car wherever it has stopped, whether that is outside Brixington Primary Academy, close to Brixington Community Church or on your own drive. Those answers settle the work and the quote, and so our technicians ask what got in, roughly how much, and if it's run. No one sets off until you've heard our price by phone. Then the tank is cleared and the system cleaned thoroughly. AdBlue crystallises and is corrosive to some of the metals in a fuel system, and so it doesn't wash out on its own — which is why that counts more here than with petrol. The filter cleaned or, if needed, swapped; clean diesel in; then a test of your car. Your engine is started next and tested to make sure it runs correctly, all before we head off. If the engine has not run, most jobs take about half an hour once we are there, using pumps that are safe on a working forecourt and quiet enough to use outside a house after dark. No money upfront; you settle up that day. At the end, the VAT invoice and a report from the engineer are handed to you for the insurer. Misfuelling cover is part of plenty of insurance policies — so use the wait to look at yours. ## About Brixington Brixington is a coastal suburban area in Devon, situated near the city of Exeter and overlooking the English Channel.
