--- title: AdBlue in a Diesel Tank Smalley Common? Read This canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/smalley-common-derbyshire/ location: Smalley Common county: Derbyshire latitude: 52.978250 longitude: -1.383390 service: AdBlue in a Diesel Tank updated: 2026-10-26 --- # How It Occurs and How to Avoid It: AdBlue in a Diesel Tank in Smalley Common Keep your engine and ignition off and phone 0333 366 0103 first — reading can wait when AdBlue is already in the diesel tank. In Smalley Common, catching it before the motor runs normally means a drain and a full flush where it stands. Reading in advance? Then what follows covers how it happens and how to prevent it ever happening. ## Why does AdBlue in a diesel motor need its own filler? Plenty of newer diesels on the roads round Smalley Common and Morley carry two liquids, not one. Diesel goes to the motor. Stored in a tank of its own, AdBlue is fed into the exhaust gas and cleans it. There's a filler for every tank. Other motors keep the AdBlue filler in the boot or under the bonnet; plenty of others have both side by side behind one flap. Filling the diesel side at the pump goes on all the time. Much less frequently, the AdBlue side is topped up — normally from a bottle, by a person working out where it goes. That gap is where the error lives. ## How does AdBlue in the diesel tank take place around Smalley Common? Rarely is it carelessness: usually three things coincide. The warning comes first. As AdBlue runs low your car tells you, and if it runs out altogether, the vehicle drops into limp mode. So the top-up is done in a hurry: on a drive off Tansley Avenue before work, or in the car park outside Bateman Arms on the way home. Then your car is new. A hire car, a new car or a company car puts the fillers where your last one did not, and your hand gets to for the cap it would have used on the old one. Nothing stops the tip once it has started, because a bottle with a spout goes into a diesel filler as easily as an AdBlue one. The bottle fits. Whether it takes place in Stanley Common or the middle of Smalley Common, it's the same few seconds. ## The AdBlue filler and the diesel filler: telling them apart Before you tip anything, whether on a drive in Lodge House Surface Mine or a forecourt in Smalley Common, check these. They take a few seconds. - Check the cap rather than going by where it sits: AdBlue ones are often blue or marked "AdBlue", and diesel caps usually are not. - Check the size: the smaller neck is, on plenty of motors, the AdBlue one. - The flap. Look inside your fuel flap for a label. Plenty of cars say there which fuel goes where. - In your boot or under the bonnet: that's where the filler sits if it's not by the diesel cap, and the handbook tells you which. - Collecting a hire or company car, perhaps at the car park at Langley Mill? Ask the person who drove it last before leaving, rather than when the light comes on. ## Topping up AdBlue without it reaching the diesel tank On the day the light comes on — wherever it is across Derbyshire — a routine to use. - Turn off after you park — flat ground, motor off, and never rushed by All Saints Close on the verge. - Find the AdBlue filler and read the cap. Say "AdBlue" out loud as you unscrew it. It sounds daft and it does the trick. - If both sit under one flap, check your diesel cap is still closed before you lift the bottle — and leave it on. - Tip slowly, using the bottle's own spout. Stop when it's full or when the bottle is empty. - Before starting your car, shut the cap and check a second time that your diesel cap never opened off. If at stage two or three you find you have already poured into the diesel side, stop there. Never carry on to stage five. ## Already put AdBlue in your diesel tank around Smalley Common? What follows is a short order of things, beginning with no starting your motor. Don't switch the ignition on; on plenty of diesels that alone runs the fuel pump. Diluting it with extra diesel won't work, because AdBlue sinks to the base instead of mixing — and that's where your fuel is sucked from. If you are at a forecourt, whether it's the the nearest petrol station or the Texaco, ask the staff to help roll the vehicle clear of the petrol pump. Leave it where it is if you are on your own drive around Smalley Common. Stop as soon as it is safe and switch off, if the motor has already run. Smalley Common sits under 5 miles from the M1; there, take the next junction. Tell us roughly how far it went: a run towards Derby, under 10 miles away, is a bigger job than a short hop across Smalley Common. ## When our engineers get there around Smalley Common, what happens? Outside Stanley Common Church of England Primary School, close to United Church of All Saints or on your own drive: wherever the vehicle has stopped, we come to it. Which liquid was put in, the quantity, and if it ran: our technicians ask since the replies set the work and price. That price is given on the call, ahead of any van leaving. Then that tank is emptied and the system rinsed thoroughly. AdBlue crystallises and is corrosive to some of the metals in a fuel system, and so it doesn't wash out on its own — which is why that matters more with AdBlue than with petrol. The fuel filter is flushed, or replaced where it needs to be; fresh diesel goes in; and your car is tested. After that we start the engine and confirm it runs correctly before we leave. Unrun vehicles usually mean a half-hour visit after arrival. The equipment is safe on a busy forecourt, and quiet enough for a driveway after dark. You pay on the day, with nothing upfront, and get a VAT invoice and an engineer report for your insurer. It is worth looking at your policy as the van travels to you: misfuelling cover is included with many policies. ## About Smalley Common itself Smalley Common is a locality in Derbyshire, situated inland at an elevation of 123 metres, approximately 5.4 miles from Derby.
