Don't Start It: AdBlue in a Diesel Tank in Gray Street
With AdBlue in your diesel tank, your ignition remains off and so does your engine. AdBlue is urea mixed in water. It doesn't burn, it doesn't mix with diesel, and the harm it does begins when the fuel system pulls it in. Caught before your engine has run, AdBlue in a diesel tank is usually a drain and a thorough flush, done where the vehicle is in Gray Street. Before you do anything else, call 0333 366 0103.
Gray Street, AdBlue in your diesel tank: what to do at once
To do:
- Keys out — then nobody can switch anything on.
- Near moving traffic? So put the hazards on.
- The empty bottle or your receipt shows us the fluid and the amount, and so do not bin it away.
- Ring us from where you are. A postcode starting DL14 8, or the name of the closest street, gets the van to you without a search.
Not to do:
- Not even briefly, and not to shift your car: your motor stays off.
- Your ignition remains off: on many diesels, switching it on is enough to start your fuel pump.
- Do not top up with diesel to thin it. AdBlue does not dilute in diesel; it separates out.
- Even a short way down Oxford Street is too far to drive it.
- No emptying it yourself, either, on the roadside.
At a forecourt in Gray Street, whether it's the JET or another one, ask the staff to help you push your car clear of the pump. On your own drive, do not touch it at all.
What AdBlue does in a diesel tank
The engine isn't what AdBlue is made for; the exhaust is. From a dedicated reservoir it goes straight to the exhaust, cleaning what the engine lets out. A fuel pump is not made to take it, and AdBlue was never intended to travel through one.
Poured in with the diesel, it keeps separate instead of mixing — entirely unlike fuel. The pickup sucks fuel from the lowest part of the tank, and that is exactly where AdBlue ends up: being heavier than diesel, it sinks. When your pump runs, the AdBlue is top of the list to be pulled through. Before then it waits underneath the diesel, and that is why a vehicle topped up in Beech Terrace last night and never started stays the simple one, provided nobody touches your key.
Two kinds of damage come from there. Crystals and corrosion. As the water dries, it strands urea that hardens in filters and tiny channels; and, because it attacks certain metals, every part it touches suffers for as long as it stays inside. If the AdBlue is in the lines, waiting overnight around Gray Street makes it worse. In the tank alone, waiting does nothing. The water in it does damage of its own: the high-pressure pump and the injectors rely on diesel to lubricate them, and water gives them nothing.
Why is AdBlue in a diesel commonly the bigger problem?
Petrol put into a diesel on Asda's forecourt leaves the fuel thin — that is the main problem. Blended through your diesel and left still, it's harmless for now; running the motor is the damage.
AdBlue in a diesel is a different matter: not thin fuel, but no fuel at all. Not burning, it can't just be run through. Whether the car sits in Elm Terrace or the centre of Gray Street, turning it over "to see" does more harm in this case than nearly any other mistake, and the flush counts for more. The reasons: it won't remain mixed, and so diluting it fails; and deposits and corrosion outlast the next tankful.
The good news is the same as with petrol. Never started? Then the AdBlue waits just in the tank, the easiest bit of the whole system to clear, wherever your car has stopped across Durham.
How does AdBlue end up in a diesel tank around Gray Street?
No one means to do it. The AdBlue filler on plenty of vehicles sits right next to your diesel filler, occasionally under the same flap, and the two caps can look alike in poor light. Mostly it's not the forecourt: someone picks up a bottle driving home and tips it in outside the house.
A couple of familiar ways cover the majority of them. The refill is rushed outside Prince Bishops Community Primary School, after the dash flashed with a warning as the children were dropped in. Near Wilson Street, someone tips a bottle in at home in the evening. Or the vehicle is topped up in the car park outside The Red Alligator, in poor light, by someone who has never opened that flap before.
Rented vehicles, brand-new motors, company cars, or the spare car in a family with one of each: the least familiar cars see it the most. Wherever you are in Gray Street or the rest of Durham, it is the same error and the same first answer: leave the vehicle off.
Already started your engine with AdBlue in the diesel tank around Gray Street?
Then your tank is no longer where the AdBlue is. It's been pulled through the fuel filter and your lines, and if the motor ran for any time, it has got to your high-pressure pump and the fuel injectors.
You may see the motor running unevenly, smoking, losing power, showing warning lights or cutting out, perhaps on the way back from Shildon Millennium Green or halfway across Gray Street. Pull over when it is safe. Turn off. Keep the vehicle off rather than testing it again. With each start, more of that is pulled through.
On the A1(M), under 10 miles from Gray Street, the first junction is where to leave, and anywhere sensible is where to stop — not carrying on.
How far it went matters. A couple of hundred yards across Gray Street to the car park by St Mark's Church is a very different job from a run towards Durham, under 10 miles away, with the AdBlue reaching further into the system with every mile. Roughly 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 after your engine has been running. Noticed early, it very rarely leaves long-term damage.
Clearing AdBlue in a diesel in Gray Street: what it takes
Anywhere it has come to rest in Gray Street — a filling station, a lay-by, a drive, a road beside The Valley Methodist Church — the van comes to your vehicle. Which fluid got in, roughly the quantity, and whether the engine has been run: our technicians check before all else, since those decide the job.
The contaminated diesel and the urea come out together when that tank is emptied, on the spot. Residue from AdBlue will not flush out unaided, so the fuel system gets a careful flush, which matters far more here than with petrol. The fuel filter is flushed, or replaced where it needs to be; fresh diesel goes in; and your car is tested. About half an hour on site is usual for most jobs where the motor has not run. Quiet enough for use outside a house at night, and safe on a busy forecourt, our pumps are explosion-proof.
The final step is to bleed the fuel system on new diesel. Firing it up comes next, and then you head off from where your car is parked, outside Bishop Auckland or on a driveway in Gray Street. Our engineers make sure it runs correctly on clean diesel before we go. As the job is done in its entirety where your car is, a garage never comes into it. You receive a VAT invoice and an engineer report after that, which is what insurers want.

AdBlue drains across Durham, Gray Street included
Lime Terrace, Regent Street and Oak Street are among the places around Gray Street that the same vans reach, along with much of Durham further out, over the DL postcode area. Close to a border, or somewhere tricky to explain? Checking beats assuming, so ring.
No towing is needed. In Gray Street, a small village, a van that comes to you works: the vehicle is drained where it stands, whether on a driveway, a side street, a car park or a forecourt.
AdBlue in a diesel tank in Gray Street: the cost of fixing it
There is no fair single quote, because the jobs aren't the same. Three things change the price: whether the engine has run and for how long, how much AdBlue was put in, and where the vehicle is. That last one turns on whether our van can reach it safely, and an open drive is easier than a tight spot behind Eldon Community Centre.
That is why each call from Gray Street starts with the same three questions, asked before giving a figure, not after: what got in, how much, and if it has run. The replies turn a range into a straight price.
Priced on the call before the engineer heads out, the job is settled that day — card or phone, nothing in advance. Look at your policy whilst we're on the way: many include misfuelling cover.
Next to the car around Gray Street, still?
Leaving the vehicle alone is, right now, the best thing you can do. Keys out, motor off, ignition off. Ring 0333 366 0103 and tell us it's AdBlue, roughly how much, and whether it's run. Petrol in Diesel takes it from there, in Gray Street or anywhere around Durham.
