Burnt Oak: AdBlue in the Diesel Tank? Leave It Off
AdBlue in your diesel tank? Then leave the motor off — and your ignition as well. Water with urea dissolved in it: that's AdBlue. Not like fuel, it neither ignites nor blends, and no harm happens till the engine pulls it round. If your engine has not run yet, AdBlue in a diesel tank is normally drained and thoroughly flushed where the car sits in Burnt Oak. Nothing comes before calling 0333 366 0103.
AdBlue in your diesel tank in Burnt Oak: the first few minutes
To do:
- Keys out — then nobody can power anything on.
- Hazards on, if moving traffic is at all near.
- The empty bottle or the receipt shows us the fluid and the quantity, so don't throw it out.
- Call right where you are. Quote a HA8 0 postcode or the closest street name, and no one has to hunt for you.
Never do these:
- No starting the motor — not for a second, not to reposition the car.
- Turning your key to ignition alone starts the pump running on many diesels. Avoid it.
- Don't top up with diesel to dilute it. AdBlue does not mix in diesel; it separates out.
- Even a short way up Gilbert Grove is too far to drive it.
- Draining the tank yourself by the road is not one to try.
Ask the people behind the counter to help you move your vehicle away from the island if you're on a forecourt around Burnt Oak, whether it's the Shell or somewhere else. At home, your car remains exactly as it is.
What does AdBlue do in a diesel tank?
Not your engine but your exhaust is where AdBlue is meant to go. It goes into its own tank and is sprayed into the exhaust gas to clean it. Nothing in a fuel pump is designed for this fluid — and no part of it was intended to go that way.
Fuel mixes; AdBlue, after tipped in, will not. The behaviour is not at all like diesel's. Heavier than diesel, it drops and collects below it — the same spot the intake sucks from. Once the system runs, the AdBlue is top of the list to go through. Before then it waits beneath your diesel, which is why a car topped up in Edgware yesterday and never switched on stays the straightforward one, provided no one touches the key.
From there it does two kinds of harm. What remains once the water evaporates is urea, which turns into crystals: they settle in narrow passages and block filters. Worse, it eats at some metals in the fuel system, and carries on till it's cleared out. Overnight, a vehicle sitting in Burnt Oak with AdBlue in its lines grows worse; where it's just in the tank, it doesn't. Diesel protects the injection pump and every injector as it passes; water offers no lubrication, and that is a second kind of damage.
Why is AdBlue in a diesel often the bigger fault?
Petrol put into a diesel on Asda's forecourt leaves the fuel thin — that's the whole fault. No harm comes as long as it sits put, mixed into your diesel — only once your motor works on it.
The issue with AdBlue in a diesel is a totally unsuitable liquid. It does not burn, and so it can't just be run through. It doesn't stay mixed, so it can't be weakened. And crystals and corrosion do not wash out with the next tank of fuel. That's why the flush matters more with AdBlue than with petrol, and why starting your engine "to see" costs more here than nearly anywhere else, whether the car is in The Hale or the middle of Burnt Oak.
As with petrol, there's good news. Wherever in Greater London the car has come to rest, an unrun motor leaves the AdBlue yet in the reservoir: the easiest bit of a fuel system to clear.
Burnt Oak: how AdBlue ends up in a diesel tank
Nobody means to do it. The AdBlue filler on plenty of vehicles rests right next to your diesel filler, sometimes under the same flap, and the two caps can look alike in poor light. Usually it is not the forecourt: someone picks up a bottle driving home and pours it in at home.
A couple of familiar ways cover most cases. A warning light comes on during the school run, and the top-up takes place in a hurry outside The Annunciation Catholic Infant School. A driver pours the container in at home, just off Fortescue Road, as the day ends. Or the vehicle is topped up in the car park outside Hind and Hart, in poor light, by somebody who has never opened that flap before.
It occurs most in the cars motorists know least: a hire car, a new car, a company car, or the second motor of a household with one diesel and one petrol. Leave it switched off: that's the first step to an identical slip, wherever around Burnt Oak or the rest of Greater London you are.
Already started the engine with AdBlue in your diesel tank in Burnt Oak?
Then that tank is no longer where the AdBlue is. With any running, it goes on to the high-pressure pump and each injector, after passing via the fuel filter and lines.
Perhaps returning from Watling Park, or midway across Burnt Oak, your motor might go rough, smoke, lose power, light up the dash or stall. Once you safely can, pull over and switch everything off — without turning it on again to test. More of that is pulled through with each start.
On the M1, under a mile from Burnt Oak, the next junction is where to leave, and anywhere sensible is where to stop — not carrying on.
A quick hop across Burnt Oak to the car park by Woodcroft Hall is one matter; driving towards Westminster, under 10 miles away, is something else, since each mile pushes the AdBlue deeper in. So distance counts. Tell us about how far it had come.
We do all of the flushing where your car has come to a stop, and once the motor has run there is more of it. Very seldom does it leave lasting damage if it is noticed soon.
What does an AdBlue drain on a diesel involve in Burnt Oak?
A street beside Young Barnet Foundation, a driveway, a layby or a forecourt: anywhere your car has stopped around Burnt Oak, we come to it. What went in, about the quantity, plus whether your motor has been run: we check before all else, because those shape the work.
Next, emptying your tank right there takes out the polluted diesel and the AdBlue in one go. Your system is rinsed thoroughly, which matters more with AdBlue than with petrol, because what it leaves behind does not rinse out on its own. The filter is flushed, or replaced where it needs to be; clean diesel goes in; and the vehicle is tested. If the motor has not run, the majority of jobs take about half an hour once our technicians arrive. Our equipment is explosion-proof, and so a busy filling station is no fault, and it is quiet enough for a residential street late at night.
Last, the fuel system is bled with clean diesel. You set off as soon as our engineers have started the car, and it makes no difference whether your car is on a driveway in Burnt Oak or in a space at Mill Hill Broadway. Our engineers make sure it runs correctly on new diesel before we go. Since the job is done in its entirety where your car is, a workshop never comes into it. At the end, you are given paperwork for the insurer: a VAT invoice plus a report from the engineer.
