AdBlue in the Diesel Tank in Hillingdon Heath: What Now?
What to do about AdBlue in a diesel tank depends on one thing more than any other: if the motor has run since it got in. If it has not, keep it that way, whether your car is around Hillingdon Heath itself or out in Yiewsley. Phone 0333 366 0103 with your ignition and engine still off. In Hillingdon Heath, that is generally emptied and flushed on the spot. Pull over the minute you safely can then turn off, if it has been run. Stage one remains the same, even though the job grows.

At the petrol pump around Hillingdon Heath: AdBlue in a diesel
You are at the pump, the nozzle or the bottle still in your hand, and you have just noticed the cap you opened was the wrong one. It might be the the nearest petrol station, or the BP, or a different forecourt in Hillingdon Heath.
What it means: this is the best location to find out. Still in your tank, with no fuel pulled through: that's where the AdBlue is.
Next: avoid the urge to fire it up only to move away from the pump. Ask the staff to help you push the vehicle into a parking space, keep the receipt or the bottle, then ring us from the forecourt. If it cannot be moved, it can be emptied at the petrol pump: the equipment is explosion-proof and safe on a working forecourt.
AdBlue in the diesel tank at home in Hillingdon Heath
The warning light had been on for days. Only at the recycling bin, the empty container in your hand, did you look back at the cap you'd opened at the drive. Homes just off New Road are caught out as much as everywhere else.
Meaning? Provided your vehicle has not been driven since, it is close to the forecourt case. At the floor of the tank sits exactly where AdBlue stays, because it will not blend with diesel — and a night passing changes nothing of the difference.
Put the keys in the house overnight — otherwise someone might take it away at breakfast — then phone us. Your drive is where it gets emptied, whether around Hillingdon Heath or Hayes End. Even at night, the pumps stay quiet enough for a residential street.
AdBlue in a diesel and already driving around Hillingdon Heath?
A mile or two after filling up, the engine began misbehaving: roughness, smoke, less power, warnings on your dash. Fountain Close, say, or the way towards Westminster — a run of under 15 miles.
Meaning? Your pump has sucked the AdBlue up. It has been through the filter and your lines and, the further you went, into the high-pressure pump and the injectors. It goes further with each mile covered and every restart.
What to do: pull over where it's safe then switch off. Exit by the first junction — not the services further along — if you're on the M4, under 3 miles from Hillingdon Heath. Don't restart the car to see if it has cleared; it will not have. Phone us and say how far you went.
AdBlue in the wrong tank of a hire, lease or company car
You have only had this vehicle for days. The AdBlue filler sits right next to the diesel filler, which you did not know, because your own vehicle either has no AdBlue or keeps it somewhere else. It can happen to anyone, anywhere across Greater London.
The point: exactly as above, split by if it ran, but with one added stage. Any work on the car frequently needs the owner's go-ahead under hire or fleet agreements.
Next: ring the hire company or your fleet manager first, then us — settling it before our arrival is faster. If you are stranded in the car park outside West Drayton, or by Hayes End Library, whilst you wait for an answer, leave the car off.
Hillingdon Heath: unsure if it was AdBlue in your diesel tank?
"I think so" is sometimes as honest answer there is. Lighter, that bottle; a hint of ammonia round your filler; a hazy recollection of which cap. Sound familiar? Maybe on a friend's drive in Cowley Peachy, or in a rush by Hewens Primary School on the school run.
Meaning? Drips outside the filler never reach the motor at all. A diesel tank with AdBlue in it is a different story. You cannot tell which by turning the ignition, and doing so will draw in any AdBlue that is in your tank.
Assume it got in, and don't turn your engine. Ring us and explain what you saw; we would rather check a tank that turns out clean than drain one that has already been run.
Every AdBlue drain around Hillingdon Heath shares these steps
Every situation has the same start to the job. Anywhere your vehicle stands — The Turk's Head's car park, a road beside Salvation Army, a driveway, a forecourt — our van arrives and we ask about the liquid, the quantity, plus whether the engine has turned over. Answers shape the job; the quote comes by phone while nobody has left yet.
A thorough flush follows this drain. With petrol it is routine; with AdBlue it's essential, because deposits build up and some metals corrode, and neither washes out unaided. Then comes the filter — cleaned, or replaced where needed — followed by fresh diesel, and a test of your car. Not started? Then roughly half an hour once we are there is most jobs.
Starting it comes at the end. Our engineers confirm it runs smoothly on clean diesel before we go. The whole job is done where the car is, and when it is noticed quickly, permanent damage is very uncommon. Nothing is paid upfront, settlement happens on the day, and you receive what your insurer wants: an engineer report and a VAT invoice. It is worth knowing: lots of insurers offer misfuelling cover, and so a quick look at your documents as we travel is worthwhile.
