AdBlue in the Diesel Tank in Seven Kings? Keep It Switched Off
AdBlue in your diesel tank? Then leave your engine off — and your ignition as well. Water with urea dissolved in it: that is AdBlue. The trouble starts once it's sucked through the pump — it will not burn, and it won't blend with diesel. Caught before the motor has run, AdBlue in a diesel tank is generally a drain and a thorough flush, done where the vehicle is in Seven Kings. Before anything, ring us on 0333 366 0103.
Seven Kings, AdBlue in your diesel tank: what to do at once
To do:
- Pocket the keys, which prevents anyone turning the power on.
- Near moving traffic? Then put your hazards on.
- So you can give us which liquid it was and roughly how much, save your receipt or the empty bottle.
- Our van locates you quickest with a postcode starting IG3 8, or simply the name of a street close by, so call from the spot.
Not to do:
- Moving the car just a few yards is no reason to start the engine.
- Plenty of diesels power their fuel pump the instant the ignition comes on, and so leave the car off.
- Adding extra diesel doesn't help: AdBlue settles out rather than blending.
- Even a short way down Suffolk Road is too far to drive it.
- Do not try to drain the vehicle yourself at the roadside.
Ask the people behind the counter to help you move your vehicle off the pumps if you're on a forecourt around Seven Kings, whether it is the BP or elsewhere. Parked on your own driveway? Then it stays just as it is.
What does AdBlue do in a diesel tank?
Not your motor but the exhaust is where AdBlue is meant to go. From a dedicated reservoir it goes directly to the exhaust, cleaning what your engine lets out. Neither side suits the other: urea doesn't belong in an injection pump, and an injection pump can't deal with urea.
Inside a diesel tank it behaves very differently from fuel. It does not mix in. It drops, because it is denser than diesel, and settles down where the pickup takes its fuel from. When the pump runs, the AdBlue is top of the list to go through. Until then it waits beneath your diesel, which is how a car filled in Gants Hill last night and never switched on stays the simple case, provided nobody turns the key.
After it's drawn in, the harm takes two forms. It attacks some metals used in fuel systems, attacking any part it reaches until it is removed from the system. And once the water evaporates, the urea turns into crystals that block filters and settle in narrow passages. If the AdBlue is in the lines, leaving it overnight in Seven Kings makes things worse. Inside your tank only, waiting does nothing. Water protects nothing. The high-pressure pump and every injector need diesel flowing through them, and so the water part damages them in its own right.
Petrol or AdBlue in a diesel: why AdBlue is regularly worse
Petrol put into a diesel on Esso's forecourt makes the fuel watery — that is the whole fault. Blended through your diesel and sitting unused, it is no threat for now; using your motor is the damage.
The issue with AdBlue in a diesel is a totally unsuitable liquid. It can't just be run through, since it doesn't burn. Whether your car is in Little Heath or the centre of Seven Kings, turning it over "to see" does more harm with AdBlue than almost any other slip, and the flush counts for more. Why: it won't remain mixed, so watering it down fails; and deposits and corrosion outlast the following fill.
As with petrol, there is good news. Wherever in Greater London your vehicle has stopped, an unstarted motor means the AdBlue yet inside the reservoir: the easiest part of a fuel system to empty.
How AdBlue ends up in a diesel tank in Seven Kings
It's not deliberate. Many cars keep the AdBlue inlet beside the diesel one, occasionally behind a single flap, and muddling them up is simple after dark. Most of the time it takes place with a bottle bought on the way home and poured in on the driveway, not at the pump.
A couple of familiar ways account for most cases. Hurrying, outside Aldborough Primary School, after a warning lamp came on during the school run, someone tops up the car. A bottle is poured in at the end of the day on a drive just off Downshall Avenue. Or a driver new to that flap tops up your vehicle after dark, parked in the car park outside the pub in the village.
The least familiar vehicles get it the most — rentals, brand-new ones, company cars, and the spare motor of a home with both fuels. Wherever around Greater London, Seven Kings as well, the mistake doesn't change, and nor does the first step: keep it off.
Already started the engine with AdBlue in the diesel tank around Seven Kings?
The AdBlue has left your tank, then. Your filter and lines have had it pulled through, and any running carries it on to the high-pressure pump and every injector.
Perhaps coming back from Seven Kings Park, or part way across Seven Kings, your engine might run lumpy, smoke, drop pace, light up your dash or stall. Stop as soon as it is safe, switch off, and do not restart it to check. With each start, more of it is pulled through.
On the M11, under 3 miles from Seven Kings, the first junction is where to leave, and somewhere sensible is where to park — not driving on.
A quick hop across Seven Kings to the car park by St John the Evangelist, Seven Kings is one thing; driving for London, under 10 miles away, is something else, since every mile pushes the AdBlue further in. So distance counts. Roughly how far had it come? Tell us.
Once the motor has run, the flush includes more, and all of it is done where your car has ended up. Caught quickly, it very rarely leaves long-term damage.
Seven Kings: how AdBlue is emptied from a diesel
Wherever it has stopped in Seven Kings — a filling station, a lay-by, a driveway, a road beside Memorial Gardens War Memorial — our van comes to the vehicle. What got in, about how much, plus whether your motor has turned over: our technicians ask before all else, because those decide the work.
Then your tank is cleared where the car stands, so the contaminated fuel and the AdBlue come out together. A full flush matters much more with AdBlue than after petrol, since what remains won't clear 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 your engine hasn't run, most jobs take about half an hour once our technicians are there. Quiet enough to use outside a house at night, and safe on a working forecourt, the pumps are explosion-proof.
Lastly, your system is bled with fresh diesel. You set off as soon as our technicians have fired it up, and it makes no difference whether your car is on a driveway in Seven Kings or in a bay by the nearest station. Our engineers make sure it runs smoothly on clean diesel before we leave. No workshop is needed at any stage, with the whole job done on the spot. Insurers want a VAT invoice and an engineer report, and you get both afterwards.

AdBlue drains across Greater London, Seven Kings included
Newbury Park, Aldborough Hatch and Goodmayes are among the towns around Seven Kings that the same vans serve, along with much of Greater London beyond, over the IG postcode area. Close to a border, or somewhere awkward to explain? Checking beats guessing, so ring.

What AdBlue in a diesel tank costs to put right around Seven Kings
Because the callouts vary, a flat figure would not be fair. The price changes first with how long, if at all, your engine has been running, and next with the amount of AdBlue that was put in. After that it rests on where the vehicle is and whether our van can get to it safely, which is simpler on an open driveway than in a tight spot behind Ilford War Memorial Hall.
Ahead of any figure, not after, every enquiry from Seven Kings begins with the same three questions: the fuel, the quantity, plus if the engine ran. With those replies, a range shrinks to one firm figure.
You get that price by phone, before anyone heads out, and you pay on the day, by card or by phone, with nothing upfront. Misfuelling cover comes with many insurance policies, so it is worth looking at yours before the van gets there.
