--- title: Explained: AdBlue in a Diesel Tank Richmond Hill canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/richmond-hill-south-yorkshire/ location: Richmond Hill county: South Yorkshire latitude: 53.522540 longitude: -1.162030 service: AdBlue in a Diesel Tank updated: 2026-10-04 --- # Richmond Hill: How Does AdBlue End Up in a Diesel Tank, and How Do You Prevent It? Leave your engine and ignition off then ring 0333 366 0103 first — reading can wait when AdBlue is already in the diesel tank. A drain and a full flush, carried out just where your vehicle stands around Richmond Hill, is normally what it needs if caught before your engine runs. Here before the event? Then what follows covers why it happens and how to prevent it happening at all. ## Two fillers, two tanks: AdBlue in a diesel car Not one fluid but two: that's how many modern diesels around Richmond Hill and Sprotbrough Park run, with diesel for the motor. AdBlue's own tank holds it, and from there it goes to the exhaust, and there spraying cleans the fumes. There is a filler for each tank. On a lot of motors the two sit side by side under the same flap; on others the AdBlue filler is in the boot or under the bonnet. Diesel goes in at every forecourt call-out, week in, week out. Much less commonly, the AdBlue side is topped up — mostly from a bottle, by a person thinking about where it goes. That gap is where the mistake lives. ## Richmond Hill: how AdBlue in the diesel tank occurs Rarely is it carelessness: normally three things coincide. Hurry comes from the warning. Your car warns you as AdBlue runs low, and a dry tank puts the vehicle into limp mode — so the top-up happens in a rush, before work on a driveway off Newton Lane, or on the way home in the car park at The Newton Arms. Next, the hand goes for the cap it would have used on the old motor — because a rental car, a new vehicle or a company car puts the fillers somewhere your last one didn't. Nothing stops the tip after it has started, since a bottle with a spout goes into a diesel filler as readily as an AdBlue one. The bottle fits. The same few seconds decide it, in the middle of Richmond Hill or out in Newton. ## Telling the AdBlue filler from the diesel filler Before you tip anything, whether on a driveway in Scawsby or a forecourt around Richmond Hill, check these. They take a couple of seconds. - Position misleads; the cap does not. AdBlue ones tend to be blue or carry the word "AdBlue" — diesel caps usually don't. - Look at the size: the smaller filler neck is, on many vehicles, the AdBlue one. - A label inside your fuel flap often shows which fuel goes where, on many vehicles. Check for it. - The handbook says where it lives when the filler isn't next to your diesel cap: the boot, or under the bonnet. - The person who drove the vehicle last. On a hire or company car collected from somewhere like the car park at Doncaster, ask before you leave, not when the light comes on. ## Topping up AdBlue without it reaching the diesel tank The day the light goes on, wherever across South Yorkshire, use this routine. - Pull in on level, engine off, with time to spare — never rushing on the side of Allendale Road. - Say "AdBlue" out loud as you unscrew the cap, after you find the AdBlue filler and read it. Silly, perhaps, yet it works. - The diesel cap remains on. Where both share a flap, make sure it's shut before lifting the bottle. - Gently does it, through the bottle's own spout, till it is full or the bottle runs out. - Only then, start the car: close the cap, check once more, and make sure your diesel cap was never opened. Find at the second or third step that the bottle went in the diesel tank? That's where you stop. Leave out step five altogether. ## Put AdBlue in your diesel tank in Richmond Hill already? Do not start the engine: that's how the short order of things begins. On plenty of diesels the ignition alone runs the fuel pump, so do not switch it on. Filling up with diesel will not thin it: instead, AdBlue drops to the base of your tank, right where fuel is taken from. Ask the attendants to help roll your car clear of the pump if you're on a forecourt — the Texaco, the Morrisons or somewhere else. Leave it where it is if you're on your own driveway around Richmond Hill. Already run? Pull over when it is safe, then switch off. Come off the A1(M) — under a mile out of Richmond Hill — at the first exit. Roughly how far did it go? Crossing Richmond Hill is smaller work than a run of under 3 miles towards Doncaster, so say. ## What takes place when our engineers turn up in Richmond Hill Our technicians come to the vehicle wherever it has stopped, whether that's outside Richmond Hill Primary Academy, close to Sprotbrough Road Community Church or on your own drive. Our technicians ask what got in, roughly how much, and if it's run, since the answers settle this work and the quote. You hear that quote on the phone, before anyone sets off. Emptying your tank comes next, then a thorough flush of the system. With AdBlue that counts more than with petrol: it crystallises and is corrosive to some of the metals in a fuel system, and so it does not wash out on its own. The filter is flushed, or replaced where it needs to be; fresh diesel goes in; and your car is tested. Your engine is fired up next and checked to be sure it runs properly, all before our technicians go. Unrun cars mostly mean a half-hour job from the moment we arrive. The equipment is fine on a live filling station, and quiet enough for a driveway after dark. Payment is on the day, not upfront, and you are given the paperwork an insurer wants: an engineer report and a VAT invoice. Misfuelling cover is part of plenty of insurance policies — so use the wait to check yours. ## About Richmond Hill Richmond Hill is a suburban area located on the riverside in South Yorkshire, with a low elevation of around 14 metres.
