--- title: Wick: AdBlue in a Diesel Tank, Explained canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/wick-dorset/ location: Wick county: Dorset latitude: 50.727180 longitude: -1.779570 service: AdBlue in a Diesel Tank updated: 2026-10-16 --- # Wick: How Does AdBlue End Up in a Diesel Tank, and How Do You Avoid It? Keep your motor and ignition off and ring 0333 366 0103 first — the rest can wait if AdBlue is already in the diesel tank. A drain plus a thorough flush, carried out just where the car stands in Wick, is usually all it needs when found before your motor runs. Reading before the event? Then the rest covers why it comes about and what to prevent it happening at all. ## Why does AdBlue in a diesel vehicle need its own filler? Plenty of modern diesels in Tuckton, as well as Wick, run on two liquids; your motor takes only the diesel. The exhaust, not the engine, is where AdBlue goes: sprayed into the gas to fresh it, from a separate tank. Every tank has one filler of its own. Under one flap, next to each other: that is the arrangement on many vehicles. On others, AdBlue's filler sits beneath the bonnet or in the boot instead. The diesel side is filled at the petrol pump all the time. The AdBlue side is topped up far less regularly, normally from a bottle, and normally by someone who has to stop and think where it goes. The slip lives in that gap. ## AdBlue in the diesel tank in Wick: how it happens Seldom is it carelessness: usually three things line up. To start with, the warning. Low AdBlue brings a warning from the car, and running out leads to limp mode — so a rushed top-up, perhaps before work off Ariel Drive, perhaps at Thomas Tripp on the way home that evening. The old car's cap is where the hand reaches — yet a rental car, a new car or a company car keeps the fillers somewhere else. That's a second thing: an unfamiliar motor. And the bottle fits. A bottle with a spout goes into a diesel filler as easily as an AdBlue one, and so nothing stops the tip once it has started. The same few seconds decide it, in the middle of Wick or out in Hengistbury Head. ## How to tell the AdBlue filler from the diesel one A few seconds is all these take — so check them before you pour anything, on a drive in Purewell or a forecourt around Wick. - The cap. The AdBlue cap is regularly blue, or marked "AdBlue". Your diesel cap usually isn't. Read it instead of going by position. - On many vehicles, the size tells: AdBlue gets the smaller filler neck. - Lift the filler flap and check for a label — many vehicles mark which belongs in each filler just there. - 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. - Whoever had it before will know. Check as you pick up a rental or company car — from Christchurch's car park, perhaps — rather than when the light appears. ## Keeping AdBlue out of the diesel tank when you top up When the light goes on, anywhere across Dorset, follow this routine. - Turn off once parked — level ground, engine off, and not rushed beside Wick Green on the verge. - Daft as it sounds, speaking "AdBlue" out loud as you unscrew the cap does the trick — once you have found your filler and read the cap. - Both under a single flap? Then confirm the cap on your diesel filler is still closed before 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, shut the cap and look a second time that the diesel cap never opened off. Spot at stage two or three that it's already gone into your diesel side? Then stop right there. Skip step five entirely. ## Wick: already put AdBlue in your diesel tank? Brief list, then. First: the motor remains unstarted. Don't switch your ignition on; on many diesels that alone runs the fuel pump. AdBlue does not mix with diesel — it sinks to the bottom of the tank, where your fuel is sucked from — so do not top up with diesel to dilute it. The attendants at Shell, BP or another forecourt will normally lend a hand to push the vehicle away if you ask. Your own drive around Wick is where it stays. If your motor has already run, stop as soon as it is safe then switch off. The next junction means the place to leave when you are on the M27, under 25 miles from Wick. Tell us about how far it went: a run towards Southampton, under 25 miles away, is a bigger job than a short hop across Wick. ## Wick: what occurs when we get there By St Katharine's Church of England Primary School, close to The Quomps Splash Park or on your own drive: wherever your car has stopped, our technicians come to it. Our technicians ask what was put in, about how much, and if it's run, since those replies decide this work and our price. During the phone call itself, you hear the price — before anything else. Then your tank is emptied and the system purged thoroughly. Much more than with petrol, it counts here: the crystals build up, certain metals are attacked, and none of that clears away unaided, no matter how long it is left. After your filter is flushed — or renewed, if needed — fresh diesel goes in, and then your car is tested. Then our technicians start the engine and check it runs correctly before we leave. With pumps fine on a busy 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 we arrive. You pay on the day, with nothing upfront, and get a VAT invoice and an engineer report for your insurer. Misfuelling cover is included in many insurance policies — so make use of the wait to look at yours. ## About Wick Wick is a small coastal suburban area in Dorset, situated near the mouth of the River Stour and adjacent to the larger town of Christchurch. Wick sits at a low elevation of around 2 metres, with its detached housing stock reflecting the area's residential character. Wick is close to several notable local landmarks, including Hengistbury Head and the town of Southbourne. ## AdBlue drains across Dorset, Wick included Wick is a residential suburb, and the vans that cover it also work the towns around it, Southbourne and Christchurch among them, across the BH postcode area. Our van reaches you fastest with a postcode starting BH6 4. Your car stays where it is. The drain takes place on the spot, whether a driveway, a road near Tuckton Library, or a layby on the way to Wick Green. If you are near a border, or somewhere hard to describe like the back of Red House Museum, ring and ask instead of assuming. ## The short version for Wick motorists Always, the cap; after that, the tip. Petrol in Diesel drains it on the spot, anywhere across Dorset, if AdBlue has gone in your diesel tank regardless — so leave the car off and call 0333 366 0103.
