--- title: Critchill: AdBlue in a Diesel Tank, What Next canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/critchill-somerset/ location: Critchill county: Somerset latitude: 51.223770 longitude: -2.334120 service: AdBlue in a Diesel Tank updated: 2026-10-16 --- # What Now? AdBlue in the Diesel Tank in Critchill All of it turns on one fact: if the motor has started since the AdBlue went in — far more than anything else. Over in Cottles Oak or here around Critchill, an unrun motor should stay that way. Keep nothing on, call 0333 366 0103, and expect a thorough flush plus a drain, done right where your vehicle sits around Critchill. Pull over the minute it is safe then turn off, if it has been run. Step one remains unchanged, even if the job is bigger. Below: the situations we see, wherever in Somerset. Pick yours. ## At the petrol pump in Critchill: AdBlue in a diesel Just at this point, bottle yet in your hand, it dawns on you that the cap you opened was the wrong one, there at the petrol pump. Be it Sainsbury's, Texaco or somewhere else around Critchill, the case is the same. In short: there is no better spot exists to discover it. Still in the tank, and nothing drawn onwards: that is where the AdBlue is. What to do: do not get back in and start the vehicle to clear the pump. Three jobs: a push into a space with the staff assisting, the receipt kept, and a ring to us from the forecourt. Draining it right at the pump is fine when it can't be moved, because the equipment is explosion-proof. ## At home in Critchill with AdBlue in your diesel tank For days the dashboard had been warning you. A bottle from the shop, tipped in at the drive — and it was just by the bin that the cap caught your eye. It happens on driveways just off Whitemill Lane as often as anywhere. Meaning? Provided the vehicle has not been driven since, it is second to the pump case. On the floor of the tank is where AdBlue stays, since it will not mix with diesel — and a night passing changes no difference. Next: prevent any early-morning drive by putting your keys indoors, then phone us. In The Butts or here around Critchill, the drain is done on your driveway. Our equipment runs quietly enough that it won't wake the neighbours at night. ## On the road in Critchill with AdBlue in a diesel Topped up, pulled away, and before long the engine was running roughly, smoking, down on power, or flashing up the dash. Maybe heading to Bath, under 15 miles away, or just along Whitewell Road. Meaning? Your fuel pump has taken the AdBlue up. Distance sets how deep it gets: filter and pipework to begin with, then the high-pressure pump and each injector. Each mile and each restart takes it further. Next: pick a sensible place, stop, and switch your engine off. On the M4, under 25 miles from Critchill, that means the next exit, not the services further on. It will not have cleared, so there is no point restarting to check. Call us and say how far you drove. ## Hire, lease or company car with AdBlue in the wrong tank You've had the car hardly a week. Your own vehicle either has no AdBlue or puts it elsewhere, and so nothing told you the AdBlue cap was right beside the diesel. Anyone, wherever across Somerset, could do it. Put simply: an extra step on top of the situations above, which depend on whether it's run. Plenty of hire and company contracts want the owner to approve work on the car. Your move: rental firm or your fleet manager first, us second, because sorting it beforehand saves time. Leave it off while the reply comes, even if you're parked outside Frome or close to Christ Church. ## Unsure about AdBlue in the diesel tank in Critchill? Truthfully, the only answer may be that you think it did. A slight ammonia-like whiff lingers around the filler, the bottle seems too light, and which cap came off is a blur. It might have been at a friend's drive in Little Keyford, or rushing outside Trinity Church of England First School at the school run. The point: the motor is not hurt by some AdBlue spilled around the outside. The diesel tank with AdBlue in it is another story. Any AdBlue in the tank will be sucked in by firing up the car, and the start wouldn't settle which it is in any case. What to do: treat it as if it was put in. Don't start the vehicle. Ring and give the details: we would sooner confirm a clean tank than empty one once the engine has run. ## The common ground in every Critchill AdBlue drain The job begins the same way, whichever the situation. Our technicians come to the vehicle, whether it is at a forecourt, a driveway, the car park outside The Ship or a side street near Frome Town Council, and ask three things: what got in, about how much, and if your motor has run. Your price comes on the call, ahead of anyone setting off, and the replies set the work. AdBlue crystallises and eats at certain metals used in fuel systems, so it won't rinse out unaided; that's why a full flush, after this drain, matters far more here than with petrol. Clean diesel is put in once the filter has been flushed or changed, and your car is then checked. Never started? Then about half an hour once we are there is most jobs. The last step is firing it up. Our check that it runs smoothly on clean diesel comes before we leave. Long-term damage is very unusual when it's noticed early, and the whole job is done where the vehicle is. You pay on the day, with nothing upfront, and get a VAT invoice and an engineer report for your insurer. Many policies include misfuelling, so look at yours while the van travels. ## About Critchill itself Critchill is a suburban area in Somerset, situated approximately 11 miles from the city of Bath and 97 miles from London.
