--- title: AdBlue in a Diesel Tank Greenside: Explained canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/greenside-city-of-edinburgh/ location: Greenside county: City of Edinburgh latitude: 55.956920 longitude: -3.184120 service: AdBlue in a Diesel Tank updated: 2026-10-25 --- # Why It Occurs and How to Prevent It: AdBlue in a Diesel Tank in Greenside Pause reading a minute when your diesel tank already has AdBlue in it: ignition off, motor off, then call 0333 366 0103. Around Greenside, finding it before your motor turns usually leaves a drain and a full flush where it stands. Here in advance? In that case the rest covers how it comes about and how to stop it ever happening. ## Two fillers, two tanks: AdBlue in a diesel car No single liquid but two: that is how plenty of newer diesels around Greenside and Calton run, with diesel for your engine. The exhaust, not your motor, is where AdBlue goes: sprayed into the fumes to fresh them, from a separate tank. Each tank has its own filler. Many of cars have a single flap for both, while some move the AdBlue filler to the boot or under the bonnet. At the pump, your diesel side is topped up all the time. Much less commonly, the AdBlue side gets filled — mostly from a bottle, by a person working out where it goes. It's in the gap that the mistake lives. ## AdBlue in your diesel tank in Greenside: how it takes place Three things tend to line up, and carelessness is seldom one of them. First, the warning. Low AdBlue brings a message from the vehicle, and letting it run out leads to limp mode — hence a rushed top-up, perhaps before work off Greenside Row, or outside Theatre Royal on the way home after work. Then the vehicle is new. A hire car, a new vehicle or a company car puts the fillers where your last one didn't, and the hand gets to 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 tip once it has started. Hillside or the heart of Greenside: it takes the same few seconds in both. ## How to tell the AdBlue filler from the diesel one A few seconds is all the checks take — so run through them before you pour anything, on a drive in Roxburghs Court or a forecourt in Greenside. - The cap. The AdBlue cap is commonly blue, or marked "AdBlue". Your diesel cap usually is not. Read it rather than going by position. - Look at the size: the smaller neck is, on plenty of vehicles, the AdBlue one. - The flap. Look inside your fuel flap for a label. Plenty of motors say there which fuel goes where. - The handbook says which it is if your filler is not next to the diesel cap: the boot, or under the bonnet. - The previous driver will know. Ask as you pick up a hire car or fleet car — from Edinburgh Waverley's car park, say — not once the light appears. ## Keeping AdBlue out of the diesel tank when you top up Wherever in City of Edinburgh the light comes on, here is a routine for that day. - Pull in somewhere level, motor off, with time to spare — not hurried on the side of Picardy Place. - Daft as it sounds, saying "AdBlue" aloud as you unscrew the cap works — once you have found your filler and read it. - Leave the diesel cap on. If both sit under one flap, check the diesel cap is still closed before you lift the bottle. - Using the bottle's own spout, pour slowly — and stop when it's full or the bottle is empty. - Before you start the vehicle, shut the cap and check again that your diesel cap never opened off. Stop there if you find, at stage two or three, that you've already poured into your diesel side. Skip stage five altogether. ## Greenside: already put AdBlue in your diesel tank? The short order of things, starting with not starting your engine. Keep the ignition off as well, because on plenty of diesels switching it on alone runs the pump. Diluting it with extra diesel fails, since AdBlue sinks to the base instead of blending — and that's where your fuel is pulled from. The staff at BP, JET or another forecourt will normally help pushing your car clear if asked. At home in Greenside? Then the car remains where it is. If the engine has already run, stop as soon as it is safe then switch off. The next junction means where to leave when you are on the M8, under 10 miles from Greenside. Mileage counts — a short hop across Greenside makes a smaller job than driving under a mile to Edinburgh — so tell us roughly how far it went. ## When we get there around Greenside, what occurs? By the local primary school, near Edinburgh Playhouse or on your own driveway: wherever your car has stopped, our technicians come to it. Those answers settle this work and our quote, so we ask what went in, roughly how much, and whether it's run. You get that quote by phone, before anyone sets off. Your system is then purged thoroughly, after that tank is emptied. With AdBlue that matters 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, if needed, swapped; fresh diesel in; then a check of your car. Before we leave, our engineers start the car and check that it's running smoothly. With pumps safe on a busy forecourt and quiet enough to use outside a house at night, most jobs where the engine has not run need about half an hour after our engineers are there. You pay on the day, with nothing upfront, and get a VAT invoice and an engineer report for your insurer. Misfuelling cover is part of many insurance policies — and so use the wait to look at yours. ## About Greenside and where it is Greenside is a suburban area located on the coast in the City of Edinburgh, sitting at an elevation of 43 metres and close to the city centre.
