Then put this page aside a moment, keep your ignition and motor off, then ring 0333 366 0103. Caught before the motor runs, it is normally a drain and a thorough flush, done where the car is around Brimps Hill. If you're reading before it has happened, the rest of this page is about why it takes place and how to make sure it does not. ## Two fillers, two tanks: AdBlue in a diesel car Diesel goes to your motor — but many current diesels driven about Brimps Hill and Plump Hill carry another liquid too. AdBlue goes to your exhaust, where it is sprayed into the gas to clean it, and it lives in a tank of its own. Different tanks, different fillers. Some vehicles put the AdBlue filler in the boot or under the bonnet; plenty of others place both side by side under one flap. At the petrol pump, your diesel side gets filled constantly. A driver who has to stop and think where it goes normally fills the AdBlue side, from a bottle, and far less regularly. It is in the gap that the mistake lives. ## How AdBlue in your diesel tank takes place around Brimps Hill Seldom is it carelessness: usually three things line up. Haste follows from the warning. The car warns you as AdBlue runs low, and a dry tank puts the vehicle into limp mode — so the top-up gets done quickly, before work on a driveway off A4136, or on the way home in the car park outside Yew Tree. The old car's cap is where your hand reaches — but a rental car, a new motor or a company car puts the fillers elsewhere. That is a second factor: a strange motor. Lastly, the spout fits: a diesel filler or AdBlue one, it slides in just as easily, and once the pour begins, nothing stops it. Mitcheldean or the middle of Brimps Hill: it is the same few seconds in both. ## The AdBlue filler and your diesel filler: telling them apart Before you tip anything, whether on a driveway in Shapridge or a forecourt around Brimps Hill, check these. They take a couple of seconds. - Read the cap rather than going by where it sits: AdBlue ones are regularly blue or marked "AdBlue", and diesel caps normally aren't. - Many motors fit AdBlue the smaller filler of the two. - The flap. Look inside your fuel flap for a label. Plenty of vehicles say there which fuel goes where. - The handbook shows where it lives if the filler isn't next to the diesel cap: your boot, or under the bonnet. - The person who drove it last. On a hire or company car picked up from somewhere like the car park outside Gloucester, ask before you leave, not when the light comes on. ## AdBlue top-ups that never reach the diesel tank For the day the warning comes on — anywhere you are across Gloucestershire — a routine to follow. - Stop somewhere level, motor off, with time to spare — never rushing on the side of Gloucester Road. - Say "AdBlue" out loud as you unscrew the cap, after finding the AdBlue filler and read it. Daft, perhaps, yet it works. - If both sit under one flap, check your diesel cap is still closed before you lift the bottle — then leave it on. - Stop once that tank fills or the bottle is empty; before that, tip slowly using its built-in spout. - Only after that, start your car: close the cap, check again, and make sure the diesel cap was never opened. Discover during the second or third stage that AdBlue went into the diesel tank? That's where you stop. Never go on to step five. ## Brimps Hill: already put AdBlue in the diesel tank? The short order of things, beginning with not starting the motor. Don't switch the ignition on; on plenty of diesels that alone runs the fuel pump. Do not top up with diesel to thin it: AdBlue does not mix with diesel, it sinks to the bottom of that tank, where your fuel is sucked from. Ask the attendants to help roll the vehicle clear of the petrol pump if you are at a forecourt — the Gulf, the Power or anywhere else. On your own drive around Brimps Hill?

Which fluid went in, the amount, and if it ran: we ask because those replies set both work and quote. You hear that quote on the phone, before anyone sets off. Then that tank is emptied and the system purged thoroughly. With AdBlue that counts more than with petrol: it crystallises and is corrosive to some of the metals in a fuel system, so it doesn't wash out on its own. Filter flushed or, where it must be, swapped; fresh diesel in; then a check of your car. We do not leave until it has been started and is running properly. Using pumps safe on a working forecourt and quiet enough for use outside a house at night, most jobs where your engine hasn't run need about half an hour after we are there. Payment is on the day, not upfront, and you are given the paperwork your insurer asks for: an engineer report and a VAT invoice. Before we get there, have a look at your policy; plenty include cover for misfuelling. ## About Brimps Hill itself Brimps Hill is a locality in Gloucestershire, situated on the riverside at an elevation of around 105 metres.
