--- title: AdBlue in a Diesel Tank Northleach: What Now canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/northleach-gloucestershire/ location: Northleach county: Gloucestershire latitude: 51.830270 longitude: -1.837220 service: AdBlue in a Diesel Tank updated: 2026-10-08 --- # What Now? AdBlue in the Diesel Tank in Northleach All of it hinges on a single fact: whether the motor has been run since the AdBlue was added — more than anything else. Not run yet? Then leave the car like that, whether your vehicle is — Northleach or Stowell. Usually that is draining and thoroughly purging it right there in Northleach — and so leave the key and motor off and ring 0333 366 0103. Pull over the minute you safely can and switch off, if it has been run. A larger job, yes, yet the same first step. Find the scenario below that matches yours, wherever in Gloucestershire it happened. ## On a Northleach forecourt with AdBlue in a diesel 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. Possibly you're at the the nearest petrol station, possibly at the another forecourt nearby, possibly somewhere else around Northleach. In short: there is no better spot to be to discover it. The AdBlue is in that tank and nowhere else. Nothing has drawn it in. Your move: stay out of the car, however much the pump wants freeing. Get the attendants to lend a hand rolling it into a space, hold on to the bottle, then phone us right there. Emptying it right at the petrol pump is possible when it can't be shifted, since the equipment is explosion-proof. ## AdBlue in the diesel tank on a Northleach drive? The warning light had been on for days. You bought a bottle, poured it in on the drive, and only when you put the empty bottle in the recycling did you look a second time at the cap. It takes place on driveways just off Market Place as often as anywhere. Meaning? As long as the car has not been driven since, it's close to the forecourt case. At the floor of your tank is where AdBlue waits, because it won't blend with diesel — and a night passing makes no difference. Keep the keys in the house tonight — otherwise someone may take it away first thing — then phone us. We drain the car on your drive, whether that's around Northleach or out in Hampnett. Late-night clears outside a house are fine: the pumps are low-noise. ## Northleach: drove off with AdBlue in a diesel? A mile or two beyond filling up, the motor started playing up: roughness, smoke, lost power, lights on your dash. Somewhere along The Green or else heading towards Gloucester — under 25 miles away. Put simply: the AdBlue has been pulled through your fuel system. Through the filter, through the lines, and — the further the mileage — on into the injection pump and every injector. Each restart, like every mile, pushes it deeper. Pull in somewhere safe — that is the first job — then switch everything off. Leave at the first junction — not the services further along — if you are on the M5, under 15 miles from Northleach. Restarting it to check achieves nothing — AdBlue doesn't clear on its own. Roughly how far did it go? Tell us when you phone. ## AdBlue in the wrong tank of a hire, lease or company car A week ago, it was unknown to you. Unknown to you, the two fillers are side by side here — not like your own vehicle, which has no AdBlue or stores it in another spot. It can happen to anyone, anywhere around Gloucestershire. Put simply: one extra stage on top of the cases above, and those depend on if it's run. Plenty of hire and company agreements want the owner to approve work on the vehicle. Settling it before we turn up is faster, and so ring the hire company or your fleet manager, and then us. Hanging on for an answer at the car park outside Kingham, or beside Northleach War Memorial? Leave your car off throughout. ## Not sure it was AdBlue in the diesel tank, Northleach? Now and then, "I think so" is all you can truthfully say. The bottle is lighter than it should be, there's a faint smell of ammonia round your filler, and you can't remember which cap you took off. Perhaps it happened in a hurry at the school gates at Northleach Church of England Primary School, or on a friend's drive in Turkdean. In short: spillage round the filler does the engine unharmed. AdBlue inside the diesel tank does. You cannot tell which by turning the key, and doing so will pull in any AdBlue that is in that tank. Next: act as though it went in, and leave your motor off. Call us and explain what you saw; we would rather check a tank that turns out clean than drain one that has already been run. ## Northleach: what each AdBlue drain has in common Each situation has the same opening to the work. We come to your car, whether it is at a forecourt, a driveway, the car park outside The Sherborne Arms or a side street near Church of St Peter & St Paul, and ask three things: what got in, about how much, and if the engine has run. On the phone, before dispatch, you are told our price, and those replies decide the job too. AdBlue forms crystals and eats at some metals in fuel systems, so it does not wash out on its own; that is why the flush, after the drain, counts much more with AdBlue than with petrol. Finally come your filter, flushed or replaced as needed; clean diesel; and a check of the vehicle. If your motor hasn't run, most jobs take about half an hour once we are there. Starting it comes last. Our technicians confirm it runs correctly on clean diesel before leaving. The entire job is done where the car is, and when it's spotted quickly, long-term damage is very rare. Nothing is taken upfront, settlement is made on the day, and you get what the insurer wants: an engineer report plus a VAT invoice. Worth remembering: lots of insurers offer misfuelling cover, so a quick look at your documents as you wait is worthwhile. ## About Northleach and where it is Northleach is a small town in Gloucestershire, situated on the banks of the River Leach at an elevation of around 165 metres.
