Barnsbury: AdBlue in the Diesel Tank? Leave It Off
With AdBlue in your diesel tank, your ignition remains off and so does the engine. Water with urea mixed in it: that is AdBlue. Being water-based, it won't ignite and never combines with diesel; trouble only starts once your pump begins pulling it. Caught before the engine has been run, AdBlue in a diesel tank is normally a drain and a thorough flush, done where your car is around Barnsbury. Before anything, call us on 0333 366 0103.
Barnsbury, AdBlue in the diesel tank: what to do right away
Things to do:
- So no one can switch the ignition on, pull your keys out.
- If you are anywhere near moving traffic, put the hazards on.
- Which fluid, and roughly how much quantity? Hang on to the bottle or your receipt, and our technicians will see.
- Ring just where you are. Quote a N1 1 postcode or the nearest street name, and nobody has to search for you.
Don't do these:
- Not even for a second, and not to roll the vehicle: your engine stays off.
- Switching your key to ignition by itself starts the pump going on many diesels. Avoid it.
- No extra fuel on top. The AdBlue will not mix, so it's pointless.
- Any driving at all is to be avoided, including a short way along Offord Street.
- No emptying it yourself, at all, at the roadside.
The attendants on duty at any Barnsbury filling station — the Texaco included — will usually help pushing it aside if you ask. If you are on your own drive, leave it precisely where it is.
AdBlue in a diesel tank, and what it does there
The engine is not what AdBlue is made for; the exhaust is. From a separate reservoir it is fed directly to the exhaust, treating what your engine emits. Nothing inside a fuel pump is made for this liquid — and none of that was intended to go that way.
Fuel mixes; AdBlue, once poured in, will not. Its behaviour is not at all like diesel's. Denser than diesel, it drops and collects underneath it — the very spot the intake draws from. The first thing the fuel system pulls through, once it runs, is the AdBlue. So a car that had AdBlue poured in on a drive in Pentonville last night, and has not been started since, is still the easy case: the AdBlue is lying at the bottom of your tank, and nothing has drawn it in.
It causes two kinds of harm from there. As its water goes, the urea left behind crystallises, and the crystals block filters and settle in fine passages. And it is corrosive to some of the metals a fuel system is made from, and so it keeps working on the components it hits for as long as it stays there. Where the AdBlue has reached the pipework, leaving it overnight in Barnsbury makes things worse. Inside the tank only, waiting costs nothing. Water lubricates nothing. The high-pressure pump and each injector need diesel flowing past them, so the water part harms them by itself.
Why is AdBlue in a diesel often the bigger fault?
A fault of thinned fuel is what you get after fuelling a diesel with petrol from the Shell. No harm comes while it stays unused, mixed into the diesel — only when the engine runs on it.
With AdBlue in a diesel, the fluid itself is plainly the wrong one. Since it does not burn, running it through is not an option. Nor can it be thinned, since it separates back out — and the next fill will not rinse away deposits or corrosion. So the flush counts more with AdBlue, and turning your key "to see", in the centre of Barnsbury or out in St Pancras, does more harm than almost any other mistake.
The same good news applies as with petrol. Never started? Then the AdBlue sits only inside your tank, the simplest bit of the whole system to empty, wherever the vehicle has stopped in Greater London.
How AdBlue ends up in a diesel tank in Barnsbury
It's not on purpose. Many vehicles keep the AdBlue cap alongside the diesel inlet, now and then under one flap, and muddling them up is easy after dark. Usually it is not the filling station: someone buys a bottle heading home and pours it in outside the house.
Mostly, it takes place in one of a couple of familiar ways. Midway through the drop-off, the dashboard warns, and outside Thornhill Primary School the refill is rushed. Close to Crescent Street, a driver pours a container in at home in the evening. Otherwise, in dim light by Hemingford Arms, the car is topped up by a driver opening that flap the first time.
It happens most in the vehicles motorists know least: a hire car, a new car, a company car, or the second car of a household with one diesel and one petrol. Leave it switched off: that's the first step to the same slip, anywhere in Barnsbury or the remainder of Greater London you happen to be.
Already started the engine with AdBlue in the diesel tank around Barnsbury?
If so, the AdBlue is no longer in the tank. It's been pulled through the fuel filter and the fuel lines, and if your motor ran for any time, it has got to the high-pressure fuel pump and the injectors.
Watch for lumpy running, smoke, lost power, warnings on the dash, or a stall — returning from Barnsbury Wood, perhaps, or midway across Barnsbury. Pull over when safe. Turn off. Keep it off rather than restarting it to check. With each start, more of it is pulled through.
Barnsbury lies under 10 miles from the M1; if you were on it, leave at the first junction and pull up somewhere safe rather than carrying on.
Every mile pushes the AdBlue further in. That is why crossing Barnsbury to park near St. Andrew's and a drive of under 3 miles for London are such different jobs. Tell us roughly how far it had come.
Our technicians do all of the rinsing where the vehicle has ended up, and once the motor has been started there is more of it. Noticed early, it very rarely leaves lasting damage.
What does an AdBlue drain on a diesel involve in Barnsbury?
Wherever it has stopped in Barnsbury — a forecourt, a layby, a drive, a street by West Library — the van comes to the vehicle. Three replies shape the work, so first we ask what got in, roughly what quantity, and if the engine has run.
Then that tank is cleared where the car sits, and so the polluted fuel and the AdBlue come out together. The system is flushed thoroughly, which counts more with AdBlue than with petrol, since what it leaves behind does not rinse out on its own. After that, your filter: cleaned, or replaced when it has to be. Then clean diesel, and then a check of your vehicle. Engine not run? Then count on about half an hour once we are there for most jobs. Explosion-proof pumps make a live forecourt safe to work on, and they run quiet enough not to disturb the neighbours at night.
Lastly, the fuel system is bled with fresh diesel. You set off as soon as we have fired it up, and it makes no difference whether the car is on a drive around Barnsbury or in a space outside Caledonian Road & Barnsbury. It's tested on new diesel to make sure it runs smoothly before we head off. The entire job is done where your car is, so it never has to be taken to a garage. You receive a VAT invoice and an engineer report later, which is what insurers ask for.

What AdBlue in a diesel tank costs to put right around Barnsbury
No single figure could be honest, since each job is different. What moves the cost is, first, whether the engine has been running and for how long; then how much AdBlue got in; and finally where your car is and whether a van can reach it safely, which is simpler on an open drive than in a tight spot behind RIGPA Tibetan Buddhist Centre.
Which fluid went in, how much, plus whether it ran: each Barnsbury enquiry opens with exactly that, ahead of a figure, not afterwards. Once they are answered, a range becomes a single fixed number.
Our price is given during the call, before a van leaves; settling up happens on the day, by card or over the phone, with nothing upfront. Misfuelling cover is part of plenty of insurance policies, so it is worth looking at yours before the van arrives.
