Don't Start It: AdBlue in a Diesel Tank in Becontree Heath
If AdBlue has gone into the diesel tank, leave your engine off then keep the ignition off. In plain terms, AdBlue is just urea in water. Unlike fuel, it neither ignites nor mixes, and no harm starts until your motor sucks it round. In Becontree Heath, AdBlue in a diesel tank caught before the engine runs normally comes down to a drain and a thorough flush, just where the car is. Call 0333 366 0103 before you do anything else.
AdBlue in the diesel tank in Becontree Heath: the first few minutes
Things to do:
- Pull the keys out, so nobody switches your ignition on.
- Close to moving traffic? So put your hazards on.
- So you can give us which fluid it was and about how much, save the receipt or the empty bottle.
- Call just where you are. Quote a RM8 1 postcode or the nearest street name, and no one has to hunt for you.
Do not do these:
- Not even for a second, and not to shift the vehicle: your motor remains off.
- Your ignition remains off: on lots of diesels, switching it on is enough to run the pump.
- No extra fuel added. The AdBlue won't blend, so it is wasted.
- Any driving at all is best avoided, including a short stretch along Fambridge Road.
- No emptying it yourself, either, at the roadside.
Ask the people behind the counter to help you roll your car off the pumps if you are at a forecourt around Becontree Heath, whether it's the Shell or somewhere else. If you are on your own drive, leave the vehicle precisely where it sits.
What does AdBlue do in a diesel tank?
The engine is not what AdBlue is made for; the exhaust is. Kept in a dedicated tank, it's injected into the exhaust stream to treat the fumes. Nothing in it is meant to pass through a fuel pump, and nothing in a fuel pump is made to handle it.
Tipped in with your diesel, it keeps apart instead of mixing — quite different from fuel. The intake takes fuel from the lowest part of that tank, and that's precisely where AdBlue ends up: as it is heavier than diesel, it sinks. Simplest of all: a vehicle that got AdBlue in Goodmayes overnight and hasn't turned since. The liquid waits at the base of the tank, undrawn — though it would be first through if your motor runs, ahead of any diesel at all.
Once it is sucked in, the harm comes in two forms. It eats at some metals found in fuel components, attacking whatever it touches till it's cleared from the system. And once the water evaporates, the urea forms crystals that clog filters and settle in tiny passages. Lines holding AdBlue spell harm overnight for a car sitting in Becontree Heath. Only in the tank, it stays the same. Diesel lubricates the injection pump and each injector as it flows; water offers none of that, which is a separate form of harm.
Why is AdBlue in a diesel often the bigger fault?
Fill a diesel with petrol by mistake at the JET, and the problem is thinned fuel. It mixes with your diesel, and whilst it's in that tank it does no harm; the harm comes from running the motor on it.
The trouble with AdBlue in a diesel is a totally wrong liquid. It cannot just be run through, because it doesn't burn. It doesn't stay mixed, so it can't be thinned. And crystals and corrosion do not wash out with the next tank of fuel. That is why the flush counts more with AdBlue than with petrol, and why starting your motor "to see" costs more here than nearly anywhere else, whether the vehicle is in Dagenham or the middle of Becontree Heath.
The good news is the same as with petrol. If your engine hasn't run, the AdBlue is still in that tank, and your tank is the simplest part of a fuel system to clear, wherever across Greater London the car is sitting.
Becontree Heath: how AdBlue ends up in a diesel tank
Nobody means to do it. The AdBlue filler on plenty of cars sits right next to your diesel filler, occasionally under the same flap, and the two caps can look alike in poor light. A bottle picked up when driving home and poured in outside the house, instead of at the forecourt, is the typical story.
Mostly, it occurs in one of a few familiar ways. The top-up gets hurried outside William Bellamy Primary School, after your dash flashed with a warning while the kids were taken in. After work, a bottle goes in on a drive near Temple Avenue. Or someone new to that flap tops up your car after dark, stopped in the car park by The Three Travellers.
The least familiar vehicles see it the most — rentals, brand-new ones, fleet cars, and the other motor in a family with one of each fuel types. Wherever in Greater London, Becontree Heath included, the mistake does not change, and nor does the first step: leave it off.
Already started your engine with AdBlue in your diesel tank in Becontree Heath?
Then your tank is no longer where the AdBlue is. It has been sucked through the filter and your lines, and if the motor ran for any time, it has got to the high-pressure fuel pump and the fuel injectors.
Watch for lumpy running, exhaust smoke, falling power, lights on the dash, or a cut-out — coming back from Robert Clack Upper - Playing Field, say, or part way across Becontree Heath. No restarting to test: stop once safe, then turn it off. More of that is pulled through with each start.
On the M11, under 5 miles from Becontree Heath, the next junction is where to leave, and anywhere safe is where to park — not carrying on.
Hopping across Becontree Heath to the car park by Pillar of Fire Ministries is one matter; heading for London, under 15 miles away, is another, since each mile carries the AdBlue further in. So mileage counts. Let us know about how far it had come.
There's more to flush once the engine has run, and our engineers do all of it where your car has come to a stop. Caught early, it very rarely leaves lasting damage.
What does an AdBlue drain on a diesel involve around Becontree Heath?
Wherever it has stopped around Becontree Heath — a filling station, a layby, a driveway, a street beside Hartley Brook Church — the van travels to the car. Three answers decide the job, and so before anything else our technicians ask what got in, about the amount, plus if the motor has run.
The polluted diesel and the urea leave together when that tank is drained, right there. What remains from AdBlue won't wash out unaided, and so the whole system gets a careful flush, which matters far more here than with petrol. Testing your vehicle follows last, after fresh diesel is added and your filter is flushed or, where necessary, replaced. Roughly half an hour once we arrive is typical for most jobs where the motor has not run. The pumps are explosion-proof, safe on a busy forecourt and quiet enough to use outside a house at night.
The final step is to prime your system on fresh diesel. Starting the engine comes next, and then you set off from where your car is parked, outside Chadwell Heath or on a drive around Becontree Heath. It's checked on fresh diesel to confirm it runs smoothly before we go. As the job is done in full where your car is, a garage never comes into it. At the end, there is the paperwork for your insurer: a VAT invoice plus a written report from the engineer.

What AdBlue in a diesel tank costs to put right in Becontree Heath
Since the jobs vary, a flat price would not be fair.
