Read This canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/newtown-dorset-bh21-3/ location: Newtown county: Dorset latitude: 50.774780 longitude: -2.020720 service: AdBlue in a Diesel Tank updated: 2026-10-06 --- # Preventing AdBlue in a Diesel Tank in Newtown: Why It Happens Keep the engine and ignition off then phone 0333 366 0103 now — reading can wait if AdBlue is already in the diesel tank. Caught before your motor runs, it's normally a drain and a thorough flush, done where the car is around Newtown. The remainder of this page covers why it takes place and how to ensure it doesn't — handy if you're reading before it has happened. ## AdBlue in a diesel vehicle, and its separate tank Many modern diesels on the roads about Newtown and Rushcombe Bottom carry two liquids, not one. Diesel goes to the motor. Its own tank keeps it, and from there it is sent to your exhaust, where a spray treats the fumes. Each tank comes with one filler of its own. Other motors put the AdBlue filler in the boot or under the bonnet; a lot more have both together under one flap. 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 someone who has to stop and think where it goes. The mistake grows in that gap between them. ## How AdBlue in the diesel tank occurs around Newtown Carelessness seldom causes it. What does is three things lining up at once. The warning comes first. As AdBlue runs low your car tells you, and if it runs out altogether, your vehicle goes into limp mode. So the top-up is done in a hurry: on a driveway off Orchard Lane before work, or in the car park outside The Dorset Soldier on the way home. Then, your hand goes for the cap it knew on the old car — because a rental car, a new vehicle or a company car places the fillers somewhere your last one didn't. A spout-topped bottle meets no obstacle at a diesel filler any more than at an AdBlue one. So the tip, after started, carries on. The same few seconds settle it, in the middle of Newtown or out in Corfe Mullen. ## The AdBlue filler and your diesel filler: telling them apart Whether a Newtown forecourt or a drive out in East End, spend a couple of seconds on these before anything is poured in. - Where it sits can mislead; the cap does not. AdBlue caps are often blue or bear the name "AdBlue" — diesel caps usually don't. - The size. On plenty of cars the AdBlue filler neck is the smaller of the two. - Open the filler flap and look for a label — plenty of motors show what belongs in each inlet right there. - The handbook. If the filler isn't by the diesel cap, it's in your boot or under the bonnet, and the handbook says which. - The previous driver knows. Ask as you collect a rental or fleet car — at Hamworthy's car park, say — rather than once the light appears. ## AdBlue top-ups that never reach your diesel tank When the light goes on, anywhere around Dorset, use this routine. - Turn off after you park — flat ground, motor stopped, and not in a rush beside Brook Lane on the verge. - Locate the AdBlue filler, read the cap, and speak the word "AdBlue" aloud as you unscrew it. It sounds daft. It does the trick. - Leave the diesel cap on. If both sit under one flap, check the diesel cap is still closed before you lift the bottle. - Using the bottle's own spout, tip slowly — and stop when it's full or the bottle is empty. - Only then, start the car: close the cap, check again, and make sure your diesel cap was never opened. Discover during the second or third step that AdBlue went in the wrong tank? That's where you stop. Skip step five altogether. ## AdBlue in your diesel tank already, around Newtown? Don't start your motor: that is where the short order of things starts. Do not switch the ignition on; on many diesels that alone runs the fuel pump. AdBlue doesn't mix with diesel — it sinks to the bottom of your tank, where the fuel is pulled from — so don't top up with diesel to dilute it. The staff at Esso, Shell or any forecourt will normally help to push the vehicle clear if asked. Your own drive in Newtown is the place it should stay. Where your motor has run by now, stop somewhere safe then turn the car off. Leave the M27 — under 25 miles out of Newtown — at the first exit. Tell us about how far it went: a run towards Salisbury, under 25 miles away, is a bigger job than a short hop across Newtown. ## Our arrival around Newtown, and what occurs next Our van reaches your car wherever it stopped — your own driveway, near Corfe Mullen Children's Centre and Library, or by Henbury View First School. What liquid went in, the quantity, and whether it ran: we ask because the replies set both work and price. No one sets off until you have had our quote over the phone. Next: draining, then a full flush of the entire system. More than with petrol, it counts here: crystals build up, certain metals are attacked, and nothing washes away on its own, no matter how long it sits. The filter flushed or, if needed, swapped; fresh diesel in; and then a test of your car. Before leaving, our technicians start it and make sure that it's running properly. Using pumps safe on a working forecourt and quiet enough for use outside a house at night, most jobs where your engine hasn't run need roughly half an hour once our engineers are there. The insurer usually wants the engineer's report and the VAT invoice, and both are yours at the end. Payment is on the day, with no deposit. It is worth looking at your policy while we travel to you: misfuelling cover is included with many policies. ## About Newtown and where it is Newtown is a suburban area in Dorset, situated near the coast and approximately 75 metres above sea level.
