AdBlue in a Diesel Tank in Hunters Yard? Don't Start It
With AdBlue in your diesel tank, the ignition stays off and so does your engine. Urea mixed in water is what AdBlue is. Unlike fuel, it neither burns nor mixes, and no harm happens till the engine pulls it round. Caught before your motor has run, AdBlue in a diesel tank is generally a drain and a thorough flush, done where your car is around Hunters Yard. Before anything, ring us on 0333 366 0103.
Those opening minutes: AdBlue in the diesel tank around Hunters Yard
Do these:
- Keys out — that way no one can power anything on.
- Close to moving traffic? Then put your hazards on.
- Keep the till receipt or the empty bottle, and so you can tell us what was put in and about how much.
- Give us a postcode starting HP22 4, or whichever street lies nearest, and our van finds you straight — so ring from wherever you stand.
Things not to do:
- Don't start the engine, even for a moment to shift your car.
- Switching your key to ignition by itself sets the pump running on many diesels. Skip it.
- No extra fuel on top. The AdBlue will not blend, so it's pointless.
- Any driving at all is to be avoided, even a short way along Oving Road.
- Don't try to drain the car yourself at the roadside.
The attendants on duty at any Hunters Yard forecourt — the Gulf included — will usually help pushing it clear if you ask. If you're on your own drive, leave the car just where it stands.
AdBlue in a diesel tank, and what it does there
AdBlue is made for the exhaust, not your engine. It goes into its own tank and is sprayed into the exhaust gas to clean it. Nothing inside a fuel pump is designed for this fluid — and none of that was intended to travel through one.
Inside a diesel tank it acts very differently from fuel. It does not mix in. The intake sucks fuel from the lowest part of the tank, and that's exactly where AdBlue settles: as it is denser than diesel, it sinks. Once your pump runs, the AdBlue is top of the list to go through. Until then it sits underneath your diesel, which is how a vehicle filled in Hardwick last night and not started stays the simple one, provided nobody touches the key.
From there it causes two kinds of harm. It eats at some metals used in fuel components, working on whatever it touches till it is cleared from your system. And when the water goes, the urea turns into crystals that block filters and lodge in tiny passages. Overnight, a car parked around Hunters Yard with AdBlue in its lines gets worse; if it's just inside the tank, nothing changes. Water protects nothing. The injection pump and each injector depend on diesel running past them, and so the water part harms them by itself.
Petrol or AdBlue in a diesel: why AdBlue is often worse
Fill a diesel with petrol in error over at the Applegreen, and this problem is thinned fuel. Blended into your diesel and sitting still, it's no threat at that stage; using the engine does the harm.
With AdBlue in a diesel, the liquid itself is simply the wrong one. It does not burn, so it can't just be run through. Nor can it be thinned, because it separates again — and the next fill will not clear away deposits or corrosion. So the flush matters for more with AdBlue, and trying your engine "to see", in the heart of Hunters Yard or out in Pitchcott, costs more than almost any other error.
The same good news applies as with petrol. Clearing a tank is the simplest job on any fuel system, and without start-up, the AdBlue remains in there — wherever across Buckinghamshire your vehicle has stopped.
Hunters Yard: how AdBlue ends up in a diesel tank
It's not deliberate. Plenty of vehicles have the AdBlue inlet beside the diesel one, now and then behind one flap, and mixing them up is easy in poor light. It mostly happens at home, from a bottle grabbed on the journey home, not at the forecourt.
A couple of familiar ways account for most cases. Hurrying, outside Whitchurch Combined School, after a warning lamp came on during the school run, someone tops up the vehicle. Someone tips the container in outside their house, just off Crabsgrove, as the day ends. Otherwise, after dark outside The White Swan, the car gets refilled by a driver opening that flap for the first time.
It occurs most in the cars drivers know least: a hire car, a new motor, a company car, or the second vehicle of a household with one diesel and one petrol. Wherever you are around Hunters Yard or the rest of Buckinghamshire, it is the same slip and the same first answer: leave the vehicle off.
Hunters Yard: started the motor with AdBlue in your diesel tank?
In that case, the AdBlue is no longer in your tank. It's been sucked through the fuel filter and your lines, and if your motor ran for any time, it has reached the high-pressure pump and your injectors.
Lumpy running, smoke, dropping power, dashboard warnings or cutting out: any might appear, perhaps midway across Hunters Yard or coming back from Evelyn's Patch. Stop as soon as it is safe, switch off, and do not restart it to check. Each start pulls more of that through.
Hunters Yard lies under 15 miles from the M40; if you were on it, leave by the next junction and pull up safely rather than driving on.
Mileage matters: each mile carries the AdBlue deeper into your system, and so heading for Milton Keynes, under 15 miles away, gives a far bigger job than crossing Hunters Yard to the car park by Whitchurch Methodist Church. About how far it had come is worth telling us.
Wherever your car came to a stop is where all of it gets done, even with more to rinse out once the motor has been running. When it is noticed early, long-term damage is very rare.
What draining AdBlue from a diesel involves in Hunters Yard
A road beside St John the Evangelist, a driveway, a layby or a forecourt: wherever your vehicle has come to rest in Hunters Yard, our technicians travel to it. Which fluid was put in, about how much, and if the motor has turned over: we ask first, because those shape the job.
Right there, your tank is then emptied, and both the contaminated diesel and the urea come out as one. What remains from AdBlue won't wash out by itself, so the fuel system gets a full flush, which counts far more with urea than with petrol. Clean diesel goes in once your filter is cleaned — or swapped, when it needs to be — and after that your vehicle is tested. Not run? Then expect about half an hour on site for most jobs. Explosion-proof pumps make a live forecourt safe to work on, and they run quiet enough to spare the neighbours at night.
The final step is to bleed the fuel system on clean diesel. You set off as soon as we have started the car, and it makes no difference whether the car is on a drive around Hunters Yard or in a bay outside Aylesbury Vale Parkway. It's checked on new diesel to make sure it runs smoothly before we head off. Our engineers do it all wherever your car has ended up, and it never has to go to a workshop. Afterwards, you are given the paperwork for your insurer: a VAT invoice plus a report from the engineer.

AdBlue in a diesel tank in Hunters Yard: the cost of fixing it
Because the callouts differ, a flat figure would not be honest. Whether your engine has been running, and for how long, comes first in what moves the cost. How much AdBlue got in comes next, and then the location of your car, because an open drive is simpler for a van to get to safely than a tight spot behind St John's Hall.
What got in, how much, plus whether it ran: each Hunters Yard enquiry begins by asking precisely that, ahead of a quote, not afterwards. Given them, the range narrows to a single firm figure.
Before anyone sets off, you are told the price on the phone. Then you pay on the day, card or by phone, with nothing in advance. Misfuelling cover comes with plenty of insurance policies, so it pays to look at yours before the van gets there.
