--- title: South Woodchester: AdBlue in a Diesel Tank, What Next canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/south-woodchester-gloucestershire/ location: South Woodchester county: Gloucestershire latitude: 51.717880 longitude: -2.234160 service: AdBlue in a Diesel Tank updated: 2026-10-17 --- # AdBlue in the Diesel Tank in South Woodchester, and What to Do Next What to do about AdBlue in a diesel tank depends on one thing more than any other: if your motor has run since it got in. Out in Littleworth or here around South Woodchester, an unstarted engine should remain that way. Call 0333 366 0103 with the ignition and engine still off. Across South Woodchester, such a case is typically drained and cleaned where it stands. Already started? Stop once you safely can, then turn everything off. A larger job, then, yet the same opening move. Find the scenario below that matches yours, wherever around Gloucestershire it happened. ## On a South Woodchester forecourt with AdBlue in a diesel Only now, nozzle yet in hand, you realise that the cap you took off was the wrong one, right at the petrol pump. Maybe you're at the Shell, perhaps at the Esso, perhaps somewhere else in South Woodchester. Meaning? Finding out here is as good as it gets. Still in your tank, and no fuel drawn through: that is where the AdBlue sits. What to do: don't get back in and start the vehicle to clear the petrol pump. Ring us from the forecourt after your car sits in a space — the attendants will lend a hand to roll it — and keep the receipt. Can't move it beside the petrol pump? Explosion-proof equipment keeps a busy forecourt sensible, and so we can drain the car where it is. ## AdBlue in your diesel tank on a South Woodchester drive? On the dash, a reminder had been lit for days. A bottle from the shop, tipped in on the driveway — and it was only at the recycling that the cap caught your eye. Homes just off Bospin Lane get caught out as much as everywhere else. In short: if your car has not been driven since, it's nearly as good as finding out at the pump. At the floor of the tank is exactly where AdBlue stays, since it will not mix with diesel — and a night passing changes nothing of the difference. Next: prevent any early-morning drive by putting your keys indoors, then phone us. Our technicians drain the vehicle on your driveway, whether that is in South Woodchester or out in Woodchester. Even at night, our pumps stay quiet enough for a residential street. ## On the road around South Woodchester with AdBlue in a diesel A short way after filling up, the motor started misbehaving: roughness, smoke, less power, lights on your dash. Somewhere on High Street or on the road to Gloucester — under 15 miles away. What it means: the fuel system has pulled the AdBlue in. The high-pressure pump and each injector see it as well on a longer trip, once your filter and lines have it. More miles, more restarts: further it goes. Do this: pull up anywhere sensible, then turn your engine off. On the M5, under 5 miles from South Woodchester, that means the next junction, not the services further on. Restarting it to check achieves nothing — AdBlue never clears itself. Roughly how far had it go? Say so as you call. ## A hire or company car with AdBlue in the wrong tank? Seven days back, it was new to you. Your own car either does without AdBlue or keeps it somewhere different, and so no one told you the AdBlue inlet sits right beside your diesel. Wherever you happen to be in Gloucestershire, any motorist could be caught. In short: an extra step on top of the cases above, and those turn on if it has run. Any work on your car often requires the owner's go-ahead under rental or fleet agreements. What to do: call the hire firm or your fleet manager first, then us. That's quicker settled before we get there than after. Stuck near St Mary's Church or outside Stroud until someone answers, the car remains switched off the whole time. ## Not sure it was AdBlue in your diesel tank, South Woodchester? Truthfully, the only answer may be that you think so. Which cap came off, you cannot say; but the bottle feels less than expected, and a whiff of ammonia hangs by the filler. Maybe on a friend's driveway in Rooksmoor, or rushing by Woodchester Endowed Church of England Aided Primary School at the school run. Put simply: spillage near your filler leaves the engine unharmed. A diesel tank with AdBlue inside is a different story. Any AdBlue in that tank will be sucked in by firing up the car, and the start wouldn't settle which it is in any case. Next: act as though it went in, then keep the engine off. Ring us and explain what you saw; we would rather check a tank that turns out free of AdBlue than drain one that has already been run. ## South Woodchester: what each AdBlue drain has in common Every case has the same start to the work. Wherever the car stands — The Ram Inn's car park, a road by Woodchester Village Hall, a drive, a filling station — the van arrives and asks for the fluid, the quantity, and if your motor has turned over. Replies set the job; the quote comes on the call whilst nobody has left yet. AdBlue crystallises and eats at some metals used in fuel systems, so it won't wash out unaided; that's why the flush, after the drain, matters far more here than with petrol. Your filter is flushed, or replaced where it needs to be; clean diesel goes in; and the vehicle is tested. Where your engine has not run, expect about half an hour on site, for most jobs. Starting the engine comes at the end. Our check that it runs correctly on fresh diesel comes before we head off. Long-term damage is very unusual when it is caught soon, and the whole job is done where the car is. Nothing is paid upfront, payment is made on the day, and you receive what your insurer wants: an engineer report and a VAT invoice. It is worth remembering: lots of insurers include misfuelling cover, so a quick look at your policy as we travel is worthwhile. ## About South Woodchester South Woodchester is a suburban area in Gloucestershire, situated near the River Frome at an elevation of around 85 metres.
