--- title: Flemington: AdBlue in a Diesel Tank, Explained canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/flemington-south-lanarkshire-g72-7/ location: Flemington county: South Lanarkshire latitude: 55.810990 longitude: -4.137620 service: AdBlue in a Diesel Tank updated: 2026-10-16 --- # Avoiding AdBlue in a Diesel Tank in Flemington: Why It Happens AdBlue already in the diesel tank? Then set this page aside a moment, leave the ignition and engine off, and ring 0333 366 0103. Around Flemington, catching it before the engine runs normally leaves a drain and a full flush on the spot. Reading in advance? Then what follows covers how it happens and what to stop it happening at all. ## AdBlue in a diesel car: two tanks, two fillers No single fluid but two: that is how many modern diesels near Flemington and Dalton run, with diesel feeding the engine. The exhaust, not the motor, is where AdBlue ends up: sprayed into the gas to fresh them, from its own tank. Separate tanks, separate fillers. Other motors put the AdBlue filler in the boot or under the bonnet; a lot of others place both side by side under one flap. At the petrol pump, the diesel side is topped up all the time. The AdBlue side is topped up far less often, usually from a bottle, and usually by a person who has to stop and think where it goes. It's in that gap that the error happens. ## AdBlue in your diesel tank around Flemington: how it takes place It's hardly ever carelessness. Three things tend to line up. On a drive off New Road before work, or in the car park at Newton Arms heading home: that's where the rushed top-up takes place. Why the rush? As AdBlue runs low the car tells you, and once it's empty, limp mode follows. The old car's cap is where the hand goes — but a rental car, a new car or a company car puts the fillers elsewhere. That is the second factor: an unfamiliar vehicle. Lastly, the spout goes in: a diesel filler or AdBlue one, it slides in as readily, and once the pour begins, nothing stops it. The same few seconds decide it, in the middle of Flemington or out in Hallside. ## The AdBlue filler and your diesel filler: telling them apart A couple of seconds is all the checks take — so run through them before you tip anything, on a drive in Westburn or a forecourt around Flemington. - Where it sits misleads; the cap doesn't. AdBlue caps are often blue or carry the name "AdBlue" — diesel caps normally don't. - The size. On plenty of motors the AdBlue filler neck is the smaller of the two. - A label inside the fuel flap often says which fuel goes where, on many motors. Look for it. - Cannot see it beside the diesel filler? In that case check below the bonnet or in the boot — the owner's manual will say which. - Check with the person who drove it last — before you leave, not when the light comes on — when you pick up a hire or company car from somewhere like the car park outside Newton. ## Topping up AdBlue without it reaching your diesel tank Anywhere around South Lanarkshire the light comes on, here is a routine for the day. - Stop somewhere level, motor off, with time to spare — never hurried on the side of Claude Avenue. - Find the AdBlue filler and read the cap. Say "AdBlue" out loud as you unscrew it. It sounds daft and it works. - Both under a single flap? So confirm the cap on the diesel filler stays shut ahead of lifting the bottle. - Using the bottle's own spout, tip slowly — and stop when it is full or the bottle is empty. - Before you start the vehicle, close the cap and look a second time that your diesel cap never opened off. Discover during the second or third stage that AdBlue went in the diesel tank? That is where you stop. Skip step five entirely. ## Put AdBlue in your diesel tank in Flemington already? What follows is a short order of things, beginning with not starting the motor. Leave your ignition off too, because on many diesels switching it on alone starts your pump. Thinning it with more diesel fails, since AdBlue settles to the bottom rather than blending — and that is where the fuel is pulled from. Ask the staff to help push the vehicle clear of the pump if you're at a forecourt — the the nearest petrol station, the Morrisons or anywhere else. Your own driveway around Flemington is where it stays. Stop as soon as it is safe and switch off, if the engine has already run. On the M74, under 3 miles from Flemington, that means the next exit. Distance matters — a quick hop across Flemington makes a smaller job than heading under 10 miles to Glasgow — so tell us about how far it went. ## What occurs when our engineers get there in Flemington Outside the local primary school, near Flemington Hallside Parish Church or on your own driveway: wherever your car has stopped, our technicians come to it. What liquid got in, the quantity, and whether it ran: we ask since the replies set the work and price. That price comes on the call, before any van leaves. Emptying your tank comes next, then a full flush of the fuel 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. Testing comes last: before that, fresh diesel goes in, and the filter is flushed or changed if necessary. Before we go, we start it and make sure that it's running smoothly. If your motor hasn't run, the majority of jobs take about half an hour once we're there, using pumps that are safe on a working forecourt and quiet enough to use outside a house at night. You pay on the day, with nothing upfront, and get a VAT invoice and an engineer report for your insurer. It's worth checking your insurance while we travel to you: misfuelling cover is included with plenty of policies. ## About Flemington, briefly Flemington is a suburban area situated on the riverside in South Lanarkshire, with a mix of housing types dominated by detached homes.
