--- title: AdBlue in a Diesel Tank The Reddings: What Now canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/the-reddings-gloucestershire/ location: The Reddings county: Gloucestershire latitude: 51.887930 longitude: -2.132100 service: AdBlue in a Diesel Tank updated: 2026-10-20 --- # The Reddings: AdBlue in the Diesel Tank? Find Your Situation One fact counts most when AdBlue is in a diesel tank, and it is whether your engine has been started afterwards. Wherever your vehicle is — Bamfurlong, The Reddings — don't run an engine that hasn't been started yet. Call 0333 366 0103 with the key and engine still off. Across The Reddings, that is generally emptied and flushed where it stands. If it has run, stop as soon as it is safe and switch off. It's a bigger job, though stage one does not change. Match what happened to one of the ones below, wherever across Gloucestershire you are. ## On a The Reddings forecourt with AdBlue in a diesel Only at this point, bottle yet in your hand, it dawns on you that the cap you took off was the wrong one, right at the petrol pump. Possibly you're at the Asda, possibly at the Esso, perhaps somewhere else around The Reddings. The point: of all places to find out, this is the best. The AdBlue is in your tank and nowhere else. Nothing has drawn it in. What to do: don't get back in and fire it up to clear the petrol pump. A few jobs: a shove into a space with the attendants assisting, the bottle kept, and a ring to us from the forecourt. Draining it right at the petrol pump is fine when it cannot be moved, since the equipment is explosion-proof. ## The Reddings, at home: AdBlue in the diesel tank On the dash, a warning had shown all week. Only at the recycling bin, the empty bottle in hand, did you look back at the cap you'd used at the driveway. Drives close to Leyson Road get it as much as anywhere. In short: if the car hasn't been driven since, it's almost as good as finding out at the pump. On the floor of that tank is where AdBlue stays, since it won't blend with diesel — and a night going by changes nothing of the difference. Next: prevent an early drive by putting your keys in the house, then phone us. Our technicians drain it on your driveway, whether that is around The Reddings or out in Up Hatherley. The pumping kit runs quiet enough not to disturb the street at night. ## On the road around The Reddings with AdBlue in a diesel A short way after topping up, your engine began playing up: rough running, smoke, less power, lights on your dash. It might have been driving for Gloucester, under 10 miles away, or simply down The Reddings. What it means: the fuel system has drawn the AdBlue in. Mileage sets how deep it goes: filter and lines to begin with, then the high-pressure pump and each injector. Each mile and each restart takes it further. Your move: stop somewhere safe, then turn your motor off. The Reddings lies under a mile from the M5; on it, come off at the next junction instead of pushing on for the services. Starting it again to test achieves nothing — AdBlue doesn't clear itself. Call, saying what distance the car was driven. ## Hire, lease or company car with AdBlue in the wrong tank A week ago, the car was new to you. Your own car either has no AdBlue or puts it elsewhere, and so nothing told you the AdBlue cap sits just beside your diesel. Anywhere you are around Gloucestershire, any driver can be caught. Meaning? Whichever applies above applies too — run or not — and one further step. Plenty of rental and company agreements require the owner's approval before repairs. What to do: ring the hire firm or your fleet manager first, then us. That's quicker settled before we turn up than after. Leave the car off as the answer arrives, whether you are waiting at Cheltenham Spa or near The Reddings and District Community Centre. ## Unsure about AdBlue in the diesel tank around The Reddings? Now and then, "I think so" is all anyone can truthfully say. Which cap came off, you can't recall; meanwhile the bottle weighs lighter than expected, and a whiff of ammonia hangs by your filler. The gates of St Mark's Church of England Junior School in a hurry, perhaps, or someone's drive out in Golden Valley. What it means: a little spilled about the filler does no damage to your engine. In your diesel tank, however, AdBlue damages it. Any AdBlue in that tank would be sucked in by starting the car, and the start wouldn't settle which it is in any case. Assume it was put in, and never turn your engine. Call 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. ## What each AdBlue drain around The Reddings has in common Each situation gets the same opening to the job. Wherever your vehicle stands — The Hatherley's car park, a road beside The Pavilion, a driveway, a forecourt — our van gets there and we ask about the liquid, the amount, plus whether the engine has turned over. Over the phone, before dispatch, you hear the quote, and those answers decide the work too. Emptying that tank comes next, followed by a full flush — more important with urea than after petrol, because crystals and corrosion will not clear by themselves, no matter how long it sits. Clean diesel goes in once the filter is cleaned or changed, and the car is finally tested. Where the motor hasn't been started, expect about half an hour on site, for most jobs. Our engineers fire it up at the end. Our check that it runs properly on new diesel comes before we go. Lasting damage is very unusual when it's noticed soon, and the whole job is done where your car is. Paying is on the day, never in advance. For the insurer, there is a VAT invoice and a written report from the engineer. Plenty of policies include misfuelling, and so check yours as we head over. ## About The Reddings itself The Reddings is a suburban area located near Gloucester in Gloucestershire, sitting at an elevation of 51 metres in the inland landscape of the South West region.
