--- title: AdBlue in a Diesel Tank Weston: What Now canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/weston-hampshire/ location: Weston county: Hampshire latitude: 50.889490 longitude: -1.367910 service: AdBlue in a Diesel Tank updated: 2026-10-25 --- # AdBlue in the Diesel Tank in Weston: What Now? Has your motor run since the AdBlue was put in? That single question decides nearly everything else from here. Anywhere the vehicle is — Sholing, Weston — don't run a motor that hasn't been started yet. Normally this means draining and thoroughly cleaning it on the spot around Weston — so leave the ignition and motor off then call 0333 366 0103. When the motor has been run, pull in somewhere safe first, then turn the car off. Step one stays the same, even though the work is bigger. Below: the situations we see, wherever around Hampshire. Pick the one that fits. ## AdBlue in a diesel on a Weston forecourt The cap you unscrewed was the wrong one — and you only notice it while you are standing at the petrol pump, bottle or nozzle in hand. It might be the BP, or perhaps the Southampton Logs, or a different forecourt in Weston. Put simply: no better place exists to spot it. No pump has drawn it in, so the AdBlue sits only inside that tank. Freeing the pump is no reason to start it — and so do not get back in. Three things: a shove into a bay with the staff assisting, the receipt kept, and a ring to us from where you stand. Emptying it there at the petrol pump is possible when it cannot be moved, because the equipment is explosion-proof. ## AdBlue in your diesel tank at home in Weston For days the dash had been nagging you. Only at the recycling bin, the empty container in hand, did you glance back at the cap you'd used at the drive. Drives near Barnfield Road see it as much as any other street. Put simply: if your vehicle has not been driven since, it's almost equal to spotting it at the forecourt. As it is unable to blend, AdBlue drops to the base inside that tank and stays. One night parked changes none of that. Next: prevent any early-morning move by keeping your keys in the house, then ring us. Itchen or Weston: wherever your drive sits, that's where it gets drained. The pumps are quiet enough to use outside a house after dark. ## Weston: drove off with AdBlue in a diesel? Lumpy running, smoke, lost power or a lit dashboard started a short way beyond the top-up. It might have been heading to Southampton, under 3 miles away, or simply along Weston Lane. The point: the system has drawn AdBlue through already. The high-pressure pump and every injector see it too on a longer trip, once the filter and lines have it. Every restart, like every mile, pushes it deeper. What to do: pull over where it is safe and switch off. On the M27, under 3 miles from Weston, that means the next exit, not the services further on. No trial starts: clearing isn't something AdBlue does. Phone, and say how far your vehicle went. ## AdBlue in the wrong tank: hire, lease and company cars It is a vehicle you have had for a week. Your own car either does without AdBlue or keeps it elsewhere, and so no one warned you the AdBlue cap was just next to the diesel. It can happen to anyone, anywhere in Hampshire. What it means: the same as the situations above, depending on whether it's run, with one more step. Work on the vehicle often needs the owner's approval under rental or fleet agreements. Settling it before the van turn up is quicker, and so ring the hire company or your fleet manager, and then us. If you're stuck in the car park at Sholing, or by Holy Trinity Weston, while you wait for an answer, leave the vehicle off. ## Not sure it was AdBlue in your diesel tank, Weston? Now and then, "I think so" is all anyone can honestly say. The bottle is lighter than it should be, there is a faint smell of ammonia round the filler, and you cannot remember which cap you took off. A hurried stop by the gates of Weston Shore Infant School, or a visit to a friend in Ocean Village: either fits. Meaning? Drips around the filler don't reach your engine at all. If it's inside your diesel tank, though, it does. Starting the vehicle won't tell you which, and if there is AdBlue in the tank it will draw it in. Next: assume it got in, then leave your engine off. Call us and describe what you saw; we'd rather check a tank that turns out free of AdBlue than drain one that has already been run. ## Each AdBlue drain around Weston shares these steps Whichever scenario you are in, the job starts the same way. Forecourt, driveway, The Obelisk's car park or a road by Fox's Monument — our van comes to your vehicle, and three answers follow: which liquid, what amount, and if it has run. Those replies settle the work, and you hear our quote by phone, before anyone sets off. Draining that tank comes first, followed by a careful flush — more important after urea than after petrol, because crystals and corrosion will not go on their own, however long you wait. The filter is cleaned, or replaced where it needs to be; fresh diesel goes in; and your car is tested. If your motor has not run, most jobs take about half an hour once we are there. Our technicians start the engine at the end. Before we go, it is checked to make sure it runs properly on fresh diesel. Our technicians do the entire job where your car is, and lasting damage is very unusual if it has been spotted early. You pay on the day, with nothing upfront, and get a VAT invoice and an engineer report for your insurer. Plenty of insurance policies include misfuelling cover, so it's worth checking yours while we're on the way. ## About Weston and where it is Weston is a coastal suburban area in Hampshire, situated near the city of Southampton and overlooking the waters of Southampton Water. Weston sits at a low elevation of around 18 metres, with nearby places including Itchen, Woolston, and Peartree Green.

The van empties it in place.
