--- title: AdBlue in a Diesel Tank Aylsham: Explained canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/aylsham-norfolk/ location: Aylsham county: Norfolk latitude: 52.795010 longitude: 1.251060 service: AdBlue in a Diesel Tank updated: 2026-10-07 --- # How It Occurs and How to Avoid It: AdBlue in a Diesel Tank in Aylsham Keep your engine and ignition off and ring 0333 366 0103 first — reading can wait when AdBlue is already in your diesel tank. Around Aylsham, finding it before your motor runs usually means a drain and a thorough flush on the spot. The remainder of this page explains why it takes place and how to make sure it does not — handy if you are reading before it has happened. ## Why does AdBlue in a diesel vehicle need its own filler? Not one fluid but two: that is what plenty of modern diesels near Aylsham and Ingworth carry, with diesel feeding the motor. AdBlue goes to the exhaust, where it is sprayed into the gas to fresh it, and it lives in a tank of its own. Each tank has a filler of its own. 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. Topping up the diesel side at the pump happens constantly. Someone who has to stop and think where it goes usually fills the AdBlue side, from a bottle, and much less commonly. That gap is where the mistake lives. ## How does AdBlue in your diesel tank take place around Aylsham? Carelessness seldom causes it. What does is three things lining up together. On a driveway off Penfold Street before work, or in the car park outside Black Boys heading home: that is where the rushed top-up takes place. What is the reason for the rush? As AdBlue gets low your car tells you, and if it's empty, limp mode follows. Unfamiliar vehicles come next, as well. Rentals, new motors and company cars put their fillers differently, and habit goes for the cap used on the old one. Lastly, the spout fits: a diesel filler or AdBlue one, it goes in just as easily, and after the tip starts, nothing halts it. It takes a few seconds, be it out in Drabblegate or right in the centre of Aylsham. ## Which filler is for AdBlue, and which for diesel? A few seconds is all the checks take — so run through them before you tip anything, on a driveway in Marsham or a forecourt in Aylsham. - Read the cap rather than going by where it sits: AdBlue ones are regularly blue or marked "AdBlue", and diesel caps usually aren't. - The size. On many vehicles the AdBlue filler neck is the smaller of the two. - Check inside your fuel flap: many motors carry a label there saying which fuel goes where. - The handbook. If the filler isn't by your diesel cap, it's in the boot or under the bonnet, and the handbook says which. - Ask the person who drove it last — before you leave, not when the light comes on — if you collect a hire or company car from somewhere like the car park outside North Walsham. ## Keeping AdBlue out of the diesel tank when you top up On the day the warning comes on — anywhere you are around Norfolk — a routine to follow. - Park and switch off. Not on a slope, not with your engine running, and not in a rush on the side of Hungate Street. - Find the AdBlue filler and read the cap. Say "AdBlue" out loud as you unscrew it. It sounds silly and it does the trick. - Leave the diesel cap on. If both sit under one flap, check your diesel cap is still closed before you lift the bottle. - Gently does it, through the bottle's own spout, until it is full or the bottle runs out. - Before you start the car, shut the cap and look a second time that your diesel cap never opened off. Stop there if you find, at step two or three, that you have already poured into the diesel side. Don't go on to stage five. ## Already put AdBlue in the diesel tank around Aylsham? Don't start the engine: that's where the short order of things starts. Keep your ignition off too, since on many diesels it alone runs the fuel pump. AdBlue does not mix with diesel — it sinks to the bottom of your tank, where the fuel is drawn from — so don't top up with diesel to dilute it. The staff at BP, Gulf or another forecourt will usually help pushing the vehicle clear if you ask. If you are on your own driveway around Aylsham, leave it where it stands. If the motor has already run, stop as soon as it is safe then switch off. The next junction means the place to leave if you are on the M11, over 50 miles from Aylsham. Distance matters — a short hop across Aylsham is a smaller job than driving under 15 miles towards Norwich — so say about how far it went. ## When we arrive around Aylsham, what happens? Wherever the vehicle came to rest, be it outside St Michael's Church of England VA Primary and Nursery School, near Aylsham Library or on your own drive, our van comes to it. Those answers determine the work and the price, so our engineers ask what got in, about how much, and whether it has run. On the phone call itself, you are told our quote — ahead of anything else. After that: a drain, then a thorough flush of the whole system. 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, replaced; fresh diesel in; then a check of the vehicle. The motor is fired up next and checked to make sure it runs smoothly, all before we leave. Unstarted vehicles usually need a half-hour job after arrival. The kit is fine on a busy forecourt, and hushed enough for a driveway late at night. Your insurer will ask for an engineer's report and your VAT invoice, and both are yours at the end. Payment is on the day, with no money upfront. Misfuelling cover is part of many insurance policies — and so make use of the wait to check yours. ## About Aylsham itself Aylsham is a town situated in the eastern part of Norfolk, England, on the River Bure at an elevation of around 35 metres.
