--- title: AdBlue in a Diesel Tank Middleton Park: Explained canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/middleton-park-aberdeen-city/ location: Middleton Park county: Aberdeen City latitude: 57.193150 longitude: -2.124760 service: AdBlue in a Diesel Tank updated: 2026-10-17 --- # Avoiding AdBlue in a Diesel Tank in Middleton Park: Why It Occurs Leave the engine and ignition off then phone 0333 366 0103 now — the rest can wait when AdBlue is already in your diesel tank. A drain and a full flush, carried out just where the car sits around Middleton Park, is normally all it takes if caught before the motor runs. Not happened yet? Below, the page covers the why it happens and the ways to avoid it for good. ## AdBlue in a diesel vehicle, and its separate tank Diesel goes to your engine — yet plenty of newer diesels driven about Middleton Park and Bridgefield carry another liquid as well. AdBlue goes to your exhaust, where it is sprayed into the gas to clean it, and it lives in a tank of its own. Each tank has its own filler. Under one flap, side by side: that is the layout on many motors. Elsewhere, AdBlue's filler is beneath the bonnet or in your boot instead. The diesel side is topped up at the pump all the time. The AdBlue side is fuelled far less frequently, usually from a bottle, and normally by a person who has to stop and think where it goes. The mistake grows in that gap between them. ## Middleton Park: how AdBlue in the diesel tank happens Carelessness rarely causes it. What does is three things coming up together. Haste follows from the warning. Your car tells you as AdBlue runs low, and an empty tank sends the vehicle into limp mode — so the top-up happens in a rush, before work on a drive off Jesmond Drive, or on the way home in the car park at The Parkway Inn. Next, your hand reaches for the cap it knew on the old motor — since a rental car, a new car or a company car places the fillers somewhere your last one didn't. And the bottle fits. A bottle with a spout goes into a diesel filler as easily as an AdBlue one, and so nothing stops the tip after it has started. The same few seconds settle it, in the middle of Middleton Park or out in Danestone. ## How to tell the AdBlue filler from the diesel one Check these first, at a forecourt in Middleton Park or a driveway out in Hayton. Seconds, no more. - The cap. The AdBlue cap is commonly blue, or marked "AdBlue". Your diesel cap usually isn't. Read it instead of going by where it sits. - Many cars fit AdBlue the smaller filler of the two. - The flap. Look inside your fuel flap for a label. Plenty of motors say there which fuel goes where. - The handbook. If your filler is not by your diesel cap, it's in your boot or under the bonnet, and the handbook says which. - Check with the person who drove it last — before you leave, not when the light comes on — when you collect a hire or company car from somewhere like the car park outside Dyce. ## How to top up without AdBlue in your diesel tank A routine for the day the light comes on, wherever in Aberdeen City that is. - Not in a rush on the side of Middleton Close, not on a slope, not with your motor running: park then switch off first. - Say "AdBlue" out loud as you unscrew the cap, once you find the AdBlue filler and reading it. Daft, yes, yet it works. - The two behind a single flap? Then confirm the cap on your diesel side is still closed ahead of lifting the bottle. - Slowly is best, through the bottle's own spout, until it's full or the bottle is empty. - Only after that, start the vehicle: close the cap, check again, and make sure your diesel cap was never opened. Stop there if you find, at step two or three, that you have already poured into the diesel side. Leave out step five altogether. ## Middleton Park: already put AdBlue in your diesel tank? What follows is a short order of things, beginning with not starting the engine. On plenty of diesels the ignition alone runs the fuel pump, so don't switch it on. Filling up with diesel will not dilute it: rather than mixing, AdBlue drops to the base of your tank, right where fuel is taken from. On a forecourt — Asda, Esso or another — the attendants will usually help roll your car away, if you ask. Leave it where it is if you are on your own driveway around Middleton Park. Stop as soon as it is safe and switch off, if the engine has already run. Middleton Park sits over 50 miles from the M90; on it, take the next exit. Tell us about how far it went: a run towards Aberdeen, under 5 miles away, is a bigger job than a short hop across Middleton Park. ## When our technicians arrive in Middleton Park, what takes place? Outside the local primary school, close to Get active @ Jesmond or on your own driveway: wherever the car has stopped, our engineers come to it. Our technicians ask what went in, about how much, and if it's run, because the answers decide the work and our quote. That price comes on the call, ahead of any van leaving. Then that tank is emptied and the system rinsed thoroughly. 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 doesn't wash out on its own. Your filter is cleaned, or replaced where it needs to be; clean diesel goes in; and the car is tested. After that we fire it up and confirm it runs correctly before we go. Unstarted vehicles mostly mean a half-hour visit from the moment we arrive. The kit is safe on a busy forecourt, and hushed enough for a residential street late at night. Payment happens on the day, not upfront, and you receive the documents your insurer asks for: an engineer's report and a VAT invoice. Plenty of insurance policies include misfuelling cover, and so it is worth checking yours while we are on the way. ## About Middleton Park and where it is Middleton Park is a suburban area in Aberdeen City, situated approximately 3 miles north of Aberdeen's city centre.
