--- title: Dowds Farm: AdBlue in a Diesel Tank, What Next canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/dowds-farm-hampshire/ location: Dowds Farm county: Hampshire latitude: 50.928820 longitude: -1.305540 service: AdBlue in a Diesel Tank updated: 2026-10-06 --- # Dowds Farm: AdBlue in the Diesel Tank? Find Your Situation Has your engine turned over since the AdBlue got in? That single question settles nearly everything else from here. Not started so far? Then keep it that way, whether the vehicle is — Dowds Farm or Hedge End. Normally that means draining and thoroughly cleaning it on the spot in Dowds Farm — and so leave the ignition and motor off then phone 0333 366 0103. If it's run, stop as soon as it is safe then switch off. Step one stays the same, even if the work is bigger. Wherever across Hampshire it happened, one of the situations below fits yours. ## Dowds Farm forecourt: AdBlue in a diesel at the pump You're at the petrol pump, the nozzle or the bottle still in your hand, and you have just noticed the cap you opened was the wrong one. Maybe you are at the Sainsbury's, possibly at the Texaco, perhaps somewhere else around Dowds Farm. Meaning? Finding out here is the best it can be. The AdBlue is in that tank and nowhere else. Nothing has drawn it in. Freeing the pump is no reason to start it — and so do not get back in. Ring us from the forecourt once the vehicle sits in a space — the attendants will help push it — then save the receipt. If it cannot be moved, it can be emptied at the petrol pump: the equipment is explosion-proof and fine on a working forecourt. ## At home in Dowds Farm with AdBlue in the diesel tank Days had gone by with the warning light on. Picked up a bottle, tipped it in outside the house, binned the empty — and only then looked at the cap again, after the fact. Drives near Hansen Gardens get it as much as any other street. In short: if your car has not been driven since, it is almost as good as spotting it at the forecourt. AdBlue does not mix with diesel; it sinks to the bottom of that tank and waits there. Overnight does not change that. Put your keys indoors tonight — or a person may drive it off at breakfast — and phone us. We drain the vehicle on your drive, whether that is in Dowds Farm or out in Shamblehurst. Night-time empties outside a house are fine: the pumps are quiet. ## On the road around Dowds Farm with AdBlue in a diesel Rough running, smoke, falling power or a glowing dashboard started a short way beyond the top-up. Somewhere on Gammon Close or on the road to Southampton — under 5 miles away. What it means: the fuel system has drawn the AdBlue in. Mileage sets how far it goes: filter and pipework to begin with, then the injection pump and each injector. Each restart, like every mile, carries it on. Stop safely — that's the first job — then switch it off. Exit at the next junction — not the services further along — if you are on the M27, under a mile from Dowds Farm. It won't have cleared, and so there's no sense starting it again to check. Tell us know the distance driven when you ring. ## A hire or company car with AdBlue in the wrong tank? Seven days ago, it was unknown to you. Your own vehicle either does without AdBlue or puts it elsewhere, so nothing told you the AdBlue cap sits just beside your diesel. It can happen to anyone, anywhere around Hampshire. Meaning? Whatever applies above counts here — run or unrun — and one extra stage. Many hire and company contracts want the owner to approve work on your car. What to do: ring the hire firm or your fleet manager first, then us. That's faster settled before our engineers turn up than after. Stuck near Salvation Army Church or outside Hedge End until someone answers, your car stays switched off the whole time. ## AdBlue in the diesel tank? Not sure, in Dowds Farm Truthfully, the only answer may be that you think it did. The bottle is lighter than it should be, there is a faint smell of ammonia around the filler, and you cannot remember which cap you took off. Maybe it happened in a hurry at the school gates at Wellstead Primary School, or on a friend's drive in Thornhill Park. The upshot: your motor isn't harmed by a little AdBlue splashed on the filler. In the diesel tank, however, AdBlue harms it. Any AdBlue in your tank would be drawn in by firing up the vehicle, and the start would not settle which it is in any case. Do this: act as if it got in, and never start your motor. Ring and give what you saw: we would rather confirm a tank free of AdBlue than empty one after your motor has been run. ## The common ground in every Dowds Farm AdBlue drain Each case has the same opening to the job. Three things are asked once our technicians arrive — on a filling station, a driveway, a road beside Drummond Community Centre or the car park outside Shamblehurst Barn: the liquid, the quantity, and if it has run. Those answers determine this work, and you hear our quote on the phone, before anyone sets off. Then that tank is drained and your system rinsed thoroughly, which matters more with AdBlue than with petrol: AdBlue crystallises and is corrosive to some of the metals in a fuel system, and so it doesn't rinse out on its own. Your filter is flushed, or replaced where it needs to be; fresh diesel goes in; and your car is tested. Where the motor hasn't run, allow about half an hour on site, for most cases. The final step is firing it up. Our test that it runs correctly on new diesel comes before our engineers go. Lasting damage is very uncommon if it's spotted soon, and the whole job is done where your car is. Paying comes on the day, never upfront. For your insurer, you get a VAT invoice plus a written report from the engineer. Plenty of insurance policies include misfuelling, so look at yours as we head over. ## About Dowds Farm and where it is Dowds Farm is a suburban area located inland in Hampshire, with an elevation of 39 metres above sea level.
