--- title: AdBlue in a Diesel Tank Joppa Pans: Explained canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/joppa-pans-city-of-edinburgh/ location: Joppa Pans county: City of Edinburgh latitude: 55.948760 longitude: -3.088020 service: AdBlue in a Diesel Tank updated: 2026-10-22 --- # Preventing AdBlue in a Diesel Tank in Joppa Pans: Why It Occurs If AdBlue is already in your diesel tank, stop reading for a moment: leave your motor and the ignition off then call 0333 366 0103. In Joppa Pans, finding it before the motor runs usually means draining and a thorough flush where it stands. 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. ## AdBlue in a diesel vehicle, and its separate tank No single liquid but two: that is what many modern diesels near Joppa Pans and Stoneyhill carry, with diesel for the engine. AdBlue's own tank holds it, and from there it is sent to the exhaust, where spraying treats the gas. There's a filler for every tank. On a lot of vehicles 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 on each forecourt visit, week in, week out. Much less commonly, the AdBlue side is filled — normally from a bottle, by someone thinking about where it goes. That gap is where the error lives. ## Joppa Pans: how AdBlue in your diesel tank takes place Rarely is it carelessness: normally three things coincide. The warning comes first. As AdBlue runs low the car tells you, and if it runs out altogether, the car drops into limp mode. So the top-up is done in a hurry: on a drive off Musselburgh Road before work, or in the car park at The Ormelie Tavern on the way home. Then the car is new. A hire car, a new motor or a company car puts the fillers where your last one did not, and the hand reaches for the cap it would have 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. Whether it takes place in Joppa or the middle of Joppa Pans, it is the same few seconds. ## How to tell the AdBlue filler from the diesel one Before you tip anything, whether on a driveway in Stoneyhill Steading or a forecourt around Joppa Pans, check these. They take a few seconds. - Check the cap instead of going by where it sits: AdBlue ones are commonly blue or marked "AdBlue", and diesel ones usually are not. - The size. On many vehicles the AdBlue filler neck is the smaller of the two. - A label inside the fuel flap often says which fuel goes where, on many vehicles. Look for it. - Cannot see it next to the diesel filler? In that case look below the bonnet or in the boot — the handbook says which. - Picking up a hire or company car, say at the car park outside Brunstane? Check with the person who drove it last before leaving, rather than once the light goes on. ## Keeping AdBlue out of the diesel tank when you top up For the day the light appears — wherever it is across City of Edinburgh — a simple routine to use. - Park and switch off. Not on a slope, not with your motor running, and not in a rush on the side of Seaview Crescent. - Silly as it sounds, speaking "AdBlue" aloud as you unscrew the cap works — once you have found the filler and read the cap. - The diesel cap remains on. When the two sit under a flap, make sure it's closed before lifting the bottle. - Slowly is best, through the bottle's own spout, until 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. Stop there if you find, at step two or three, that you've already poured into the diesel side. Skip step five entirely. ## AdBlue in your diesel tank already, around Joppa Pans? Do not start your engine: that's where the short order of things begins. Leave the ignition off as well, because on plenty of diesels it by itself starts your pump. AdBlue does not mix with diesel — it sinks to the bottom of that tank, where the fuel is drawn from — so don't top up with diesel to dilute it. At a forecourt — Shell, Asda or another — the attendants will usually help push your car away, if you ask. If you are on your own drive in Joppa Pans, leave it where it is. When your motor has run by now, stop safely then turn the vehicle off. Joppa Pans lies under 10 miles from the M8; there, take the next junction. About how far did it go? Hopping across Joppa Pans is smaller a job than a trip of under 5 miles to Edinburgh, so say. ## When our technicians arrive around Joppa Pans, what happens? By the local primary school, near Coillesdene Community Hall or on your own drive: wherever the vehicle has stopped, we come to it. We ask what got in, about how much, and whether it has run, since the replies decide this work and our quote. You hear that quote on the phone, before anybody heads out. Your system is then cleaned thoroughly, once the tank is emptied. More than with petrol, it matters here: the crystals build up, some metals corrode, and none of that clears away unaided, however long it sits. The filter is cleaned, or replaced where it needs to be; fresh diesel goes in; and the car is tested. Then our technicians start it and make sure it runs smoothly before we go. Most jobs are done in about half an hour after our engineers get there, provided your motor hasn't run — and the pumps our technicians use are safe on a busy forecourt and quiet after dark outside a house. Payment happens on the day, not upfront, and you receive the paperwork an insurer wants: an engineer's report and a VAT invoice. Many insurance policies include misfuelling cover, so it is worth checking yours while we're on the way. ## About Joppa Pans, for a moment Joppa Pans is a coastal locality in the City of Edinburgh, situated near the towns of Joppa and Brunstane, with Newhailes also nearby.
