AdBlue in the Diesel Tank in Fleet Marston: What Now?
One fact matters most once AdBlue is in a diesel tank, and that is if the motor has been started afterwards. Not started so far? Then keep the vehicle like that, whether the car is — Fleet Marston or Quarrendon. Keep nothing on, phone 0333 366 0103, and count on a thorough flush plus a drain, carried out just where the car stands around Fleet Marston. If it's run, stop as soon as it is safe then switch off. A bigger job, then, but the identical first step.
Find the scenario below that matches yours, wherever in Buckinghamshire it happened.
AdBlue in a diesel on a Fleet Marston forecourt
Picture it: stood by the pump, holding the nozzle, you spot the cap you opened wasn't the correct one. Possibly you're at the Tesco, perhaps at the Applegreen, maybe somewhere else around Fleet Marston.
Meaning? Finding out on the forecourt is as good as it gets. Nothing has drawn it through, so the AdBlue sits just in that tank.
Your move: stay out of the driver's seat, however much the queue needs clearing. A few jobs: a push into a space with the attendants assisting, the bottle kept, and a ring to us from the forecourt. Emptying it right at the petrol pump is possible when it cannot be shifted, because the equipment is explosion-proof.
AdBlue in the diesel tank at home in Fleet Marston
Several days had gone by with the warning light on. A bottle from the shop, emptied in at the drive — and it's only at the recycling that the cap got your eye. It happens on driveways just off A41 as regularly as anywhere.
In short: if the car has not moved since, it's nearly as good as spotting it at the forecourt. At the bottom of the tank is where AdBlue waits, because it will not blend with diesel — and a night going by changes no difference.
What to do: leave your keys inside the house so no one moves the car in the morning. Then ring. Your driveway is where it is drained, be it around Fleet Marston or Berryfields. The pumps are quiet enough to use outside a house after dark.
AdBlue in a diesel and already driving in Fleet Marston?
Topped up, pulled away, and soon your motor was running unevenly, blowing smoke, losing power, or lighting up your dash. Valerie Way, say, or the route to Milton Keynes — a run of under 15 miles.
In short: the AdBlue has been sucked through your fuel system. The high-pressure pump and each injector get it as well on a bigger trip, after the fuel filter and pipework have had it. Every restart, like every mile, pushes it deeper.
Next: find a safe place, pull in, and turn your motor off. On the M40, under 10 miles from Fleet Marston, that means the next exit, not the services further on. No trial restarts: clearing itself isn't something AdBlue will do. Phone us and say how far you went.
AdBlue in the wrong tank: hire, lease and company vehicles
You've had this car barely a week. The AdBlue filler sits right beside the diesel filler, which you didn't know, because your own motor either has no AdBlue or keeps it somewhere else. It can happen to anyone, anywhere around Buckinghamshire.
What it means: the same as the scenarios above, depending on whether it's run, with one more stage. Any work on your car often requires the owner's approval under hire or fleet agreements.
What to do: ring the hire firm or your fleet manager first, then us. That's faster settled before our engineers get there than after. Keep the car off as the reply arrives, whether you're parked outside Aylesbury Vale Parkway or near St Mary.
Not sure it was AdBlue in your diesel tank, Fleet Marston?
"I think so" is often as honest answer there is. Too light, the bottle; a hint of ammonia near your filler; no clear recollection of which cap. Sound familiar? A rushed top-up by the gates of Green Ridge Primary Academy, or a call to a friend in Upper Winchendon: both fit.
What it means: a little spilled around your filler does no damage to your engine. Once it is inside your diesel tank, though, that changes. You can't tell which by turning the ignition, and doing so will pull in any AdBlue that is in that tank.
What to do: treat it as if it was put in. Do not start it. Checking a tank that proves clean beats emptying one after it has been run — so phone and describe to us what you saw.
Each AdBlue drain in Fleet Marston shares these stages
Whichever situation you are in, the job starts the same way. Forecourt, drive, the pub in the village's car park or a road by Berryfields Children’s Centre — our van reaches your car, and three answers come next: which fluid, which amount, and whether it ran. Answers shape the work; the quote comes by phone while nobody has set off yet.
Emptying your tank comes next, then a careful flush — more vital after urea than with petrol, since crystals and corrosion won't go by themselves, however long you wait. Last are your filter, cleaned or renewed if necessary; fresh diesel; and a check of your car. Where the motor has not been started, allow roughly half an hour once we arrive, for most jobs.
We start the car at the end. Our test that it runs smoothly on new diesel comes before our technicians go. The whole job is done where the car is, and if it is caught early, permanent damage is very uncommon. You pay on the day, with nothing upfront, and get a VAT invoice and an engineer report for your insurer. Many insurance policies include misfuelling cover, so it is worth checking yours whilst we're on the way.
