Everything turns on a single detail: whether the motor has started after the AdBlue went in — more than anything else. If it has not, keep it that way, whether the car is in Great Milton itself or out in Little Milton. Call 0333 366 0103 with the key and engine still off. Across Great Milton, such a case is generally emptied and flushed on the spot. If it's run, stop as soon as it is safe and switch off. The job is bigger, yet the first stage is the same. Match what happened to a situation from the list below, wherever around Oxfordshire you happen to be. ## At the pump around Great Milton: AdBlue in a diesel Only now, bottle still in your hand, you realise that the cap you opened was the wrong one, there at the pump. It could be the BP, or perhaps the Asda, or another forecourt around Great Milton. What it means: this is the ideal place to find out. Nothing has drawn it through, so the AdBlue sits just inside your tank. What to do: do not get back in and fire it up to clear the petrol pump. Phone us from the forecourt after your car is in a bay — the staff will lend a hand to push it — and keep the bottle. If it cannot be shifted, it can be emptied at the petrol pump: the equipment is explosion-proof and safe on a working forecourt. ## Great Milton, at home: AdBlue in the diesel tank Days had gone by with the dash light on. A bottle from the shop, emptied in on the driveway — and it's only at the bin that the cap caught a second look. Driveways near The Green see it as much as any other street. What it means: if you have not driven since, this is nearly as good as the forecourt. AdBlue does not mix with diesel; it sinks to the bottom of your tank and waits there. Overnight doesn't change that. What to do: leave the keys inside the house so no one moves your car in the morning. Then ring. Your drive is where it is emptied, be it in Great Milton or Great Haseley. The pumping kit works quiet enough not to disturb the neighbours at night. ## Great Milton: drove off with AdBlue in a diesel? Rough running, smoke, falling power or a lit dashboard started a short way after the fill. It might have been driving to Oxford, under 10 miles away, or just down Church Road. Meaning? The fuel pump has sucked the AdBlue up. It has been through the fuel filter and the fuel lines and, the further you went, into the high-pressure pump and the injectors. Each restart, like every mile, carries it on. What to do: pull over where it's safe and switch off. On the Wheatley Spur, under a mile from Great Milton, that means the next junction, not the services further on. Starting it again to check gets nothing — AdBlue doesn't clear on its own. Call us and say how far you drove. ## Hire, lease or company car with AdBlue in the wrong tank You have had the vehicle barely a week. The AdBlue filler is right next to the diesel filler, which you didn't know, since your own motor either has no AdBlue or keeps it somewhere else. Across Oxfordshire, nobody is immune. The point: just as above, split by if it ran, but with an added stage. The owner frequently needs to approve the work, under plenty of rental and company contracts. Do this: hire firm or your fleet manager to begin with, us next, because sorting it beforehand saves time. Waiting for an answer at the car park at Radley, or near Great Milton Methodist Church? Leave the engine off meanwhile. ## Great Milton: unsure whether it was AdBlue in the diesel tank? At times the fair answer is "I think so". The bottle is lighter than it should be, there's a faint smell of ammonia around the filler, and you cannot remember which cap you took off. It might have been at a friend's drive in Little Haseley, or in a rush by Great Milton Church of England Primary School on the school run. Meaning? Drips outside the inlet never touch your engine at all. In your diesel tank, by contrast, AdBlue damages it. Firing up the car will not tell you which, and if there is AdBlue in the tank it would pull it in. Assume it got in, and don't start your key. Tell us what you noticed on the phone. A clear tank checked counts as a happier result than an already-run one emptied. ## Great Milton: what every AdBlue drain has in common The job opens the same way, whatever the case. Our technicians come to your car, whether it is on a forecourt, a drive, the car park at The Bull or a side street near Saint Mary The Virgin, and ask three things: what was put in, about how much, and if your engine has run. Those replies decide the work, and you hear the price on the phone, before anyone heads out. Emptying the tank comes next, followed by a careful flush — more vital after urea than with petrol, since crystals and corrosion won't go on their own, no matter how long you wait. The fuel filter is flushed, or replaced where it needs to be; clean diesel goes in; and your car is tested. Never started? Then roughly half an hour on site is most jobs. Lastly, we fire it up. Before we go, it is checked to confirm it runs properly on new diesel. Our engineers do the entire job where your car is, and lasting damage is very rare when it has been noticed soon. Payment is on the day, never in advance. For the insurer, there is a VAT invoice plus a written report from the engineer. Dig out your insurance while we arrive: misfuelling cover comes included in many policies. ## About Great Milton and where it is Great Milton is a small village in Oxfordshire, situated approximately 7.5 miles from Oxford and 43.8 miles from London.
