Preventing AdBlue in a Diesel Tank in Devizes: Why It Occurs
Leave the motor and ignition off then phone 0333 366 0103 now — reading can wait if AdBlue is already in your diesel tank. Usually, if your motor hasn't run, it is drained and fully purged where your car is around Devizes. If you are reading before it has happened, the remainder of this page is about why it takes place and how to make sure it does not.
AdBlue in a diesel vehicle, and its separate tank
Diesel feeds the engine — yet many modern diesels seen around Devizes and Rowde carry another liquid too. Its own tank holds it, and from there it is sent to the exhaust, where a spray treats the gas.
Separate tanks, different fillers. On a lot of cars the two sit side by side under the same flap; on others the AdBlue filler is in your boot or under the bonnet. Diesel goes in on each filling station visit, again and again. Much less frequently, the AdBlue side gets filled — mostly from a bottle, by someone working out where it goes. That gap is where the mistake lives.
Devizes: how AdBlue in the diesel tank takes place
Three things tend to line up, and carelessness is seldom one of them.
Haste follows from the warning. The car warns you as AdBlue runs low, and a dry tank sends the vehicle into limp mode — so the top-up gets done in a rush, before work on a driveway off Wine Street, or on the way home in the car park outside The Silk Mercer.
Then the car is new. A hire car, a new vehicle or a company car puts the fillers where your last one didn't, and the hand reaches for the cap it would have used on the old one.
Lastly, the bottle goes in: a diesel filler or AdBlue filler, it slides in as easily, and after the tip begins, no part stops it. Whether it happens in Nursteed or the middle of Devizes, it's the same few seconds.
How to tell the AdBlue filler from the diesel one
Before you pour anything, whether on a drive in Mid Wilts Way or a forecourt around Devizes, check these. They take a couple of seconds.
- Colour and lettering: an AdBlue cap is frequently blue, or says "AdBlue", where a diesel cap normally does not. Go by the cap, not its position.
- On plenty of vehicles, size tells: AdBlue has the smaller filler neck.
- A label inside your fuel flap often says which fuel goes where, on many motors. Look for it.
- The handbook says which it is if your filler is not next to your diesel cap: the boot, or under the bonnet.
- Ask 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 at Melksham.
Keeping AdBlue out of your diesel tank when you top up
The day the light goes on, wherever across Wiltshire, use this routine.
- Pull in somewhere level, engine off, with time in hand — never hurried on the side of The Market Place.
- Find the AdBlue filler, read the cap, and speak the name "AdBlue" out loud while unscrewing it. It sounds silly. It works.
- If both sit under one flap, check your diesel cap is still closed before you lift the bottle — and leave it on.
- Finish once that tank is topped up or the bottle runs dry; before that, pour gently using its built-in spout.
- Only then, start the vehicle: close the cap, check again, and make sure the diesel cap was never opened.
If at step two or three you find you have already poured into your diesel side, stop there. Leave out stage five entirely.
Put AdBlue in the diesel tank around Devizes already?
Do not start your motor: that is how the short order of things begins. Leave the ignition off too, since on plenty of diesels switching it on alone starts the pump. Diluting it with more diesel won't work, since AdBlue settles to the base instead of blending — and that's where the fuel is drawn from.
Ask the attendants to help roll the car away from the petrol pump if you're at a forecourt — the Esso, the Murco or anywhere else. If you are on your own driveway in Devizes, leave it where it sits.
Stop as soon as it is safe and switch off, if the motor has already run. On the M4, under 15 miles from Devizes, that means the next junction. Distance matters — a short hop across Devizes makes a smaller job than heading under 25 miles to Bath — so tell us about how far it went.
Devizes: what occurs when our engineers arrive
Our van reaches your car wherever it stopped — your own driveway, beside Market Cross, or by Southbroom Infants' School. Our technicians ask what went in, about how much, and whether it's run, since those answers determine the work and the price. Nobody sets off before you've heard our price over the phone.
Draining that tank comes next, followed by a full flush of your 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 does not wash out on its own. The filter flushed or, where it must be, replaced; fresh diesel in; then a check of the vehicle. The motor is fired up next and checked to confirm it runs smoothly, all before our engineers go.
Most jobs are done in about half an hour after we arrive, as long as the motor hasn't run — and the pumps we use are safe on a busy forecourt yet quiet after dark outside a house. 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 many policies.

AdBlue drains across Wiltshire, Devizes included
Being a riverside town, Devizes has the same vans as nearby areas — Roundway, Tanis — all the way across SN postcodes and the wider area beyond. Give a postcode that starts SN10 1, and the van gets there fastest.
The car remains where it is. The drain takes place on the spot, whether a driveway, a street by Corn Exchange, or a lay-by towards Chequers Garden. Guessing won't help behind The Shambles Indoor Market, close to a boundary, or somewhere hard to describe; ring and ask.
The short version for Devizes people
Before you pour, read the cap. Petrol in Diesel drains it on the spot, anywhere in Wiltshire, if AdBlue has gone in your diesel tank regardless — so leave the vehicle off and call 0333 366 0103.
