In that case set this page aside for now, keep the ignition and motor off, and ring 0333 366 0103. Around Plumpton, finding it before your motor turns normally means a drain and a thorough flush where it stands. Nothing happened yet? Below, the rest of the page covers the reasons it occurs and the ways to prevent it for good. ## AdBlue in a diesel vehicle: two tanks, two fillers Not one fluid but two: that is what many modern diesels around Plumpton and Bowscar run, with diesel for your engine. AdBlue goes to the exhaust, where it is sprayed into the gas to fresh it, and it lives in a tank of its own. There is a filler on every tank. On a lot of motors the two sit side by side under the same flap; on others the AdBlue filler is in your boot or under the bonnet. The diesel side is topped up at the pump all the time. Seldom topped up, AdBlue usually goes in from a bottle, poured by a driver who has to stop and think which filler it needs. The mistake grows in that gap between the two. ## How does AdBlue in your diesel tank happen in Plumpton? Seldom is it carelessness: usually three things line up. Hurry follows from the warning. The car warns you as AdBlue runs low, and a dry tank sends the vehicle into limp mode — so the top-up happens quickly, before work on a driveway off Beckside, or heading home in the car park outside the pub in the village. Unfamiliar vehicles are next, as well. Rentals, new motors and company motors place their fillers in new places, and habit goes for the cap it used on the old one. 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 after it has started. It's seconds, be it in Brockleymoor or right in the centre of Plumpton. ## How to tell the AdBlue filler from the diesel one Check these first, on a forecourt around Plumpton or a drive over in Catterlen. Seconds, no more. - Read the cap rather than going by position: AdBlue ones are commonly blue or marked "AdBlue", and diesel ones normally are not. - Check the size: the smaller neck is, on plenty of motors, the AdBlue one. - Lift the filler flap and check for a label — many motors mark which belongs in which filler just there. - The handbook. If your filler isn't by the diesel cap, it is in the boot or under the bonnet, and the handbook says which. - Ask the person who drove it last — before you leave, not when the light comes on — if you pick up a hire or company car from somewhere like the car park at Lazonby & Kirkoswald. ## Topping up AdBlue without it reaching the diesel tank When the light comes on, wherever across Cumbria, use this routine. - Not in a rush on the side of Voreda Gardens, not on a slope, not with the motor running: park and switch off properly. - Say "AdBlue" out loud as you unscrew the cap, once you find the AdBlue filler and reading it. Daft, perhaps, 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 it on. - Slowly does it, through the bottle's own spout, till it's full or the bottle is empty. - Before you start your car, shut the cap and check again that your diesel cap never came off. Find at step two or three that it has already gone into the diesel side? Then stop right there. Do not go on to step five. ## Already put AdBlue in your diesel tank around Plumpton? Don't start your motor: that is how the short order of things begins. The fuel pump runs on plenty of diesels as soon as the ignition is switched on — so keep it off. Topping up with diesel will not thin it: instead, AdBlue sinks to the bottom of the tank, right where the fuel is taken from. Ask the attendants to help roll your car away from the petrol pump if you are at a forecourt — the Esso, the BP or anywhere else. If you are on your own drive around Plumpton, leave it where it is. Where the motor has run already, stop somewhere safe and turn the vehicle off. Plumpton sits under a mile from the M6; on it, take the first exit. A short hop across Plumpton is a smaller job than a run towards Carlisle, under 15 miles away, and so tell us roughly how far it went. ## What takes place when we turn up in Plumpton Our van reaches the vehicle wherever it stopped — your own drive, beside St Johns Church, or outside Plumpton School. Both the work and the price rest on three answers — which liquid, what quantity, and if it's run — so we ask. That price comes on the call, ahead of any van leaving. Draining the tank comes next, then a thorough flush of the fuel system. AdBlue crystallises and is corrosive to some of the metals in a fuel system, so it doesn't wash out on its own — which is why that counts more with AdBlue than with petrol. The fuel filter is cleaned, or replaced where it needs to be; clean diesel goes in; and your car is tested. Then our technicians start the car and confirm it runs smoothly before we leave. With pumps safe on a busy forecourt and quiet enough for use outside a house at night, most jobs where the motor hasn't run take roughly half an hour once our technicians arrive. Your insurer will ask for an engineer's report and the VAT invoice, and you get both at the end. Payment comes on the day, with no money upfront. While we travel, have a look at your insurance documents; plenty include cover for misfuelling. ## About Plumpton and where it is Plumpton is a small village in Cumbria, situated on the riverside in a rural area of the North West region.
