Kensal Rise: AdBlue in the Diesel Tank? Leave It Off
Engine off, ignition off: that's where you start if AdBlue has gone into your diesel tank. AdBlue is urea dissolved in water. It doesn't burn, it doesn't mix with diesel, and the damage it does starts when the fuel system pulls it in. Caught before the motor has been run, AdBlue in a diesel tank is normally a drain and a thorough flush, done where the vehicle is around Kensal Rise. Nothing comes before calling 0333 366 0103.
Kensal Rise, AdBlue in the diesel tank: what to do straight away
Things to do:
- So nobody can switch the ignition on, take the keys away.
- If you're at all near moving traffic, put your hazards on.
- The empty bottle or the receipt shows us the fluid and the quantity, and so don't throw it out.
- Ring us from where you are. A postcode starting NW6 6, or the name of the nearest street, brings the van to you without a search.
Never:
- Do not start your motor, even for a moment to shift the vehicle.
- Many diesels power their fuel pump the moment your ignition comes on, so keep the vehicle off.
- Don't top up with diesel to thin it. AdBlue doesn't dilute in diesel; it separates out.
- Even a short distance down Chevening Road is too far to drive the vehicle.
- Beside the road, do not attempt emptying it yourself.
At a forecourt around Kensal Rise, whether it's the Shell or another one, ask the staff to help you roll your car clear of the petrol pump. At your own driveway, do not move it at all.
What AdBlue does in a diesel tank
Meant for your exhaust, AdBlue has no business in your engine. Its own reservoir holds it, and from there it's sprayed into the exhaust, and there it treats the fumes. Neither side suits the other: urea does not belong in an injection pump, and a pump cannot take urea.
It doesn't blend. Once it's tipped into a tank of diesel, AdBlue behaves not at all like fuel. It's heavier than diesel, so it sinks and gathers at the bottom of that tank, which is where the pickup draws fuel from. The first thing your fuel system pulls through, after it runs, is the AdBlue. So a motor that had AdBlue poured in on a drive in Kensal Green last night, and hasn't been started since, is still the simple case: the AdBlue is lying at the bottom of the tank, and nothing has drawn it in.
From there it does two kinds of harm. Crystals and corrosion. As the water evaporates, it strands urea that hardens in filter elements and tiny passages; and, because it attacks certain metals, every part it reaches suffers for as long as it stays in there. By daybreak, a vehicle sitting around Kensal Rise with AdBlue through its pipework grows worse; where it is just inside the tank, it doesn't. The water in it does harm of its own: the high-pressure pump and your injectors rely on diesel to lubricate them, and water offers them nothing.
Why is AdBlue in a diesel often the bigger issue?
Put petrol in a diesel at the Sainsbury's and you have a fault of thin fuel. Blended through your diesel and sitting unused, it is no threat for now; using the engine does the damage.
AdBlue in a diesel is another problem: not thin fuel, yet no fuel at all. Since it does not burn, running it through is not an option. Deposits and corrosion remain through the next tankful, and AdBlue splits back out of the diesel, so thinning it won't work. Hence the flush matters more, and trying the engine "to see" costs more here than almost any other mistake — in Willesden Green or the centre of Kensal Rise alike.
With AdBlue, the good news is no separate from petrol. If the engine hasn't run, the AdBlue is still inside your tank, and that tank is the quickest part of a fuel system to clear, wherever in Greater London the vehicle is sitting.
How does AdBlue end up in a diesel tank in Kensal Rise?
Plenty of motors place the AdBlue cap alongside the diesel one, occasionally behind one flap, and in dim light the two can appear the same. Nobody intends it. Mostly it is not the forecourt: someone buys a container driving home and tips it in at home.
The ways it takes place are few and familiar. A warning light comes on during the school run, and the top-up happens in a hurry outside Islamia Primary School. A bottle is poured in at the end of the day on a drive just off Tiverton Road. Or your car is topped up in the car park at The Chamberlayne, in poor light, by someone who has never opened that flap before.
It occurs most in the vehicles people know least: a hire car, a new vehicle, a company car, or the second motor of a household with one diesel and one petrol. Wherever around Greater London, Kensal Rise as well, the slip doesn't change, and nor does the first response: leave it off.
Started the engine with AdBlue in the diesel tank around Kensal Rise?
If so, the AdBlue is no longer in your tank. The filter and lines have had it sucked along, and some running time takes it on to the injection pump and each injector.
You may notice your engine running unevenly, smoking, losing power, showing warning lights or cutting out, maybe on the way back from Queens Park Tennis Courts or halfway across Kensal Rise. Stop as soon as it is safe, switch off, and don't restart the vehicle to check. More of it is pulled through with each start.
If you were on the M1, under 3 miles from Kensal Rise, come off at the next exit and stop somewhere sensible instead of pressing on.
How far it went matters. A few hundred yards across Kensal Rise to the car park by Pet's corner is a very different job from a run towards Westminster, under 5 miles away, with the AdBlue reaching further into the fuel system with each mile. Let us know roughly how far it had come.
Wherever the vehicle came to a stop is where all of it gets done, even with more to flush once the motor has been started. Long-term damage is very uncommon if it is noticed early.
What does an AdBlue drain on a diesel involve around Kensal Rise?
The vehicle remains where it is, whether that is a street beside Imam Khoei Islamic Centre, a driveway, a layby or a forecourt around Kensal Rise, and the van comes to it. The job depends on three answers, which we ask for before all else — which fluid got in, the quantity, and if your motor has turned over.
The polluted diesel and the urea leave together when the tank is drained, on the spot. A full flush counts much more with AdBlue than after petrol, since what remains won't wash out by itself. Your filter is cleaned, or replaced where it needs to be; fresh diesel goes in; and the car is tested. If your motor has not run, the majority of jobs take about half an hour once our engineers arrive. Quiet enough to use outside a house at night, and safe on a working forecourt, the pumps are explosion-proof.
Lastly, the system is primed with fresh diesel. Starting the engine comes next, and then you set off from where your car is parked, by Brondesbury Park or on a drive around Kensal Rise. It is tested on fresh diesel to make sure it runs correctly before our engineers leave. We do it all wherever your car has stopped, and it never has to go to a garage. Afterwards, there is the paperwork for your insurer: a VAT invoice and a report from the engineer.

What does AdBlue in a diesel tank cost to sort out in Kensal Rise?
Each job is different, so no fixed quote is honest. Three things move the price: whether the engine has run and for how long, how much AdBlue was put in, and where the car is. That last one turns on whether our van can get to it safely, and an open driveway is simpler than a tight gap behind Church of the Transfiguration.
