Then put this page down for now, keep the ignition and engine off, then call 0333 366 0103. Normally, if your engine has not turned, it's emptied and fully purged where your vehicle is in Brompton. Here before the event? Then what follows covers how it comes about and how to prevent it ever happening. ## AdBlue in a diesel car: two tanks, two fillers Plenty of newer diesels in Bullamoor, like those in Brompton, carry on two fluids; your engine takes only the diesel. Its own tank holds it, and from there it is sent to the exhaust, and there spraying cleans the fumes. Separate tanks, separate fillers. Many of motors have a single flap for the two, whereas some move the AdBlue filler to your boot or under the bonnet. Topping up the diesel side at the pump happens all the time. Much less often, the AdBlue side is filled — normally from a bottle, by someone thinking about where it goes. The mistake lives in that gap. ## Brompton: how AdBlue in your diesel tank happens Three things tend to line up, and carelessness is rarely one of them. Haste comes from the warning. Your car tells you as AdBlue runs low, and an empty tank sends it into limp mode — so the top-up gets done quickly, before work on a driveway off Church View, or on the way home in the car park outside The Crown. The old car's filler is where your hand reaches — but a hire car, a new motor or a company car keeps the fillers somewhere else. That's a second thing: a strange motor. And the bottle fits. A bottle with a spout goes into a diesel filler as easily as an AdBlue one, so nothing stops the tip after it has started. The same few seconds settle it, in the middle of Brompton or out in Water End. ## Which filler is for AdBlue, and which for diesel? Whether a Brompton forecourt or a driveway out in Winton, spend a couple of seconds over these before anything is poured in. - Check the cap rather than going by position: AdBlue ones are often blue or marked "AdBlue", and diesel caps normally are not. - Many motors give AdBlue the smaller neck of the two. - Look inside the fuel flap: many vehicles carry a label there saying which fuel goes where. - The handbook says which it is when your filler isn't next to your diesel cap: your boot, or under the bonnet. - The previous driver will know. Ask as you pick up a rental or company car — from Northallerton's car park, perhaps — rather than when the warning comes on. ## Keeping AdBlue out of the diesel tank when you top up Wherever in North Yorkshire the light comes on, this is a routine for that day. - Stop somewhere level, motor off, with time to spare — not hurried on the side of The Green. - Say "AdBlue" out loud as you unscrew the cap, once finding the AdBlue filler and read it. Daft, yes, yet it does the trick. - If both sit under one flap, check your diesel cap is still closed before you lift the bottle — and leave the vehicle on. - Using the bottle's own spout, pour slowly — and stop when it is full or the bottle is empty. - Close the cap, then check again — making sure your diesel cap remained closed the whole time. Only then, start the vehicle. Spot at step two or three that it's already gone into your diesel side? So stop just there. Leave out stage five altogether. ## Brompton: already put AdBlue in your diesel tank? Don't start the motor: that's how the short order of things starts. Do not switch your ignition on; on plenty of diesels that alone runs the fuel pump. AdBlue does not mix with diesel — it sinks to the bottom of that tank, where your fuel is sucked from — so do not top up with diesel to dilute it. Ask the attendants to help roll the vehicle clear of the petrol pump if you are on a forecourt — the Texaco, the Asda or anywhere else. Leave it where it is if you are on your own driveway in Brompton. Already started? Stop once it is safe, then turn off. Come off the A1(M) — under 10 miles out of Brompton — at the first exit. Mileage counts — a short hop across Brompton is a smaller job than driving under 25 miles to Ripon — so say roughly how far it went. ## What takes place when we get there in Brompton Wherever your car has stopped, whether by Brompton Community Primary School, beside Brompton Methodist Church or at home, the van travels to it. Our engineers ask what was put in, about how much, and if it's run, because the replies decide the work and the price. On the phone call itself, you are told our quote — before anything else. Next: draining, then a full flush of the whole system. Unlike petrol, AdBlue leaves crystals and eats at some fuel-system metals, and none of that clears away unaided. That is why it matters more. The filter cleaned or, where needed, swapped; fresh diesel in; and then a test of your car. Before we leave, we start the car and confirm that it's running properly. Unrun vehicles usually mean a half-hour job after arrival. The kit is safe on a busy forecourt, and hushed enough for a residential street after dark. Paying happens on the day, not upfront, and you receive the documents your insurer wants: an engineer report and a VAT invoice. While we travel, take a look at your policy; plenty include cover for misfuelling. ## About Brompton and where it is Brompton is a village situated on the banks of a river in North Yorkshire, with an elevation of around 48 metres.
