Sunninghill: AdBlue in the Diesel Tank? Leave It Off
If AdBlue has gone into the diesel tank, leave your engine off and keep your ignition off. Chemically, AdBlue is simply urea in water. Not like fuel, it neither ignites nor blends, and no harm starts until the motor sucks it round. Caught before the engine has been run, AdBlue in a diesel tank is normally a drain and a thorough flush, done where the car is in Sunninghill. Before anything, phone us on 0333 366 0103.
Sunninghill, AdBlue in the diesel tank: what to do at once
Do these:
- Pocket the keys, which stops anyone switching the electrics on.
- Hazards on, if moving traffic is anywhere close.
- Which product, and roughly how much quantity? Save the bottle or the till receipt, and our technicians will know.
- Ring right where you are. Say a SL5 9 postcode or the closest street sign, and nobody has to hunt for you.
Do not:
- Don't start the engine, even for a moment to move the car.
- Your ignition stays off: on lots of diesels, switching it on is enough to start the pump.
- Pouring in more diesel does not work: AdBlue settles out instead of blending.
- Leave the vehicle where it is instead of driving it anywhere, even a short stretch along Sunninghill Road.
- Draining that tank yourself beside the road is not one to try.
At a forecourt in Sunninghill, whether it is the Esso or another one, ask the attendants to help you roll your car clear of the petrol pump. If you're on your own drive, leave the vehicle precisely where it sits.
AdBlue in a diesel tank: what it does
Made for your exhaust, AdBlue has no place in the motor. Kept in a separate tank, it's squirted into the exhaust to clean the gases. A fuel pump isn't made to cope with it, and AdBlue was never intended to go through one.
Inside a diesel tank it behaves really differently from fuel. It doesn't mix in. Heavier than diesel, it sinks and pools underneath it — the very spot the intake sucks from. Easiest of all: a vehicle that got AdBlue in Ascot last night and hasn't been started since. The AdBlue waits at the foot of the tank, undrawn — though it would be first through once your engine starts, ahead of any diesel at all.
It causes two kinds of harm from there. Crystals and corrosion. As the water evaporates, it strands urea that crystallises in filters and tiny passages; and, since it attacks certain metals, every part it touches suffers for as long as it remains inside. Where the AdBlue has reached the lines, leaving it overnight in Sunninghill makes things worse. In that tank only, time does nothing. Diesel protects the injection pump and each injector as it flows; water offers no lubrication, which is a separate form of damage.
Petrol or AdBlue in a diesel: why AdBlue is regularly worse
A fault of thinned fuel is what you end up with from filling a diesel with petrol from the Murco. It mixes with your diesel, and whilst it is inside that tank it causes no damage; the harm comes from running the engine on it.
AdBlue in a diesel is a fault of the wrong substance altogether. Since it doesn't burn, running it through isn't an option. Nor can it be watered down, since it separates back out — and the following fill will not clear away deposits or corrosion. So the flush matters for more with AdBlue, and turning your key "to see", in the centre of Sunninghill or out in Cheapside, does more harm than nearly any other error.
As with petrol, there's good news. Never started? Then the AdBlue sits just inside that tank, the simplest bit of the whole system to clear, wherever your vehicle has come to rest in Berkshire.
How does AdBlue end up in a diesel tank around Sunninghill?
No one means to do it. The AdBlue filler on plenty of motors waits right next to the diesel filler, sometimes under the same flap, and the two caps can look alike in poor light. Usually it is not the filling station: someone buys a bottle heading home and pours it in outside the house.
A couple of familiar ways account for most cases. Hurrying, outside St Michael's CofE Primary School, Sunninghill, after a warning lamp came on during the school run, a parent tops up your car. In the evening, a container is tipped in on a driveway close to Queen's Road. Else, after dark by The Carpenter's Arms, your vehicle is topped up by a driver using that flap for the first time.
It occurs most in the vehicles people know least: a hire car, a new motor, a company car, or the second motor of a household with one diesel and one petrol. Wherever you are around Sunninghill or the rest of Berkshire, it is the same slip and the same first answer: leave the car off.
Sunninghill: started the engine with AdBlue in your diesel tank?
In that case, the AdBlue is no longer inside your tank. It has been sucked through the filter and your lines, and if your motor ran for any time, it has reached the high-pressure pump and the fuel injectors.
Watch for lumpy running, smoke, falling power, lights on the dash, or a stall — coming back from Victory Field, say, or part way across Sunninghill. Stop as soon as it is safe, switch off, and do not restart the car to check. With each start, more of it is pulled through.
On the M3, under 3 miles from Sunninghill, the next junction is where to leave, and anywhere safe is where to stop — not carrying on.
Distance matters: every mile pushes the AdBlue deeper into the system, so driving towards Westminster, under 25 miles away, gives a far bigger job than hopping across Sunninghill to the car park by Sunninghill Library. Let us know roughly how far it had come.
Wherever the vehicle came to a halt is where all of it gets done, even with more to clean out once the engine has been run. When it is caught soon, lasting damage is very uncommon.
Sunninghill: how AdBlue is cleared from a diesel
A road beside Novello Theatre, a driveway, a lay-by or a filling station: wherever your car has come to rest in Sunninghill, our engineers travel to it. Before anything else our technicians ask what was put in, roughly how much, and whether your engine has run, since those replies determine this work.
The polluted diesel and the urea leave together after your tank is drained, right there. The fuel system is purged thoroughly, which counts more with AdBlue than with petrol, because what it leaves behind does not rinse out on its own. A test of the car follows last, after fresh diesel goes in and the fuel filter is cleaned or, if needed, swapped. Not run? Then expect roughly half an hour on site for most jobs. The equipment is explosion-proof, so a live filling station is no issue, and it is quiet enough for a residential street late at night.
Lastly, the fuel system is primed with fresh diesel. Starting the car comes next, and then you head off from where the car is parked, at Ascot or on a driveway around Sunninghill. The check before our engineers leave is that it runs correctly on clean diesel. No workshop is needed at any point, with the entire job done on the spot. At the end, you are given paperwork for the insurer: a VAT invoice and a report from the engineer.

What AdBlue in a diesel tank costs to put right around Sunninghill
Each job differs, and so not one single price is fair. What changes the price is, first, whether the motor has been running and for how long; then how much AdBlue was put in; and then where the car is and whether a technician can reach it safely, which is easier on an open driveway than in a tight spot behind Cordes Hall.
That is why every call from Sunninghill starts with the same three queries, asked before giving a figure, not after: what got in, how much, and if it has run. Those answers shrink a range down to a single figure.
The quote is given on the call, before anyone sets off; payment comes on the day, by card or over the phone, with nothing upfront. Misfuelling cover comes with many insurance policies, so it pays to look at yours before the van arrives.
