Greenford: AdBlue in the Diesel Tank? Leave It Off
If AdBlue has got into the diesel tank, keep the motor off and keep your ignition off. Urea mixed in water is what AdBlue is. The trouble starts once it's pulled through the pump — it won't ignite, and it will not combine with diesel. In Greenford, AdBlue in a diesel tank found before your motor runs usually comes down to a drain and a thorough flush, right where your car is. First, phone us on 0333 366 0103.
Greenford, AdBlue in the diesel tank: what to do straight away
Things to do:
- Pull the keys out, so nobody switches your ignition on.
- Put the hazards on if you're anywhere close to moving traffic.
- Hold on to the receipt or the empty bottle, and so you can tell us what was put in and about how much.
- Ring us from where you are. A postcode starting UB6 9, or the name of the closest street, brings our van to you without a search.
Things not to do:
- Shifting your vehicle just a few yards is no reason to start the motor.
- Turning the key to ignition by itself sets your pump going on many diesels. Avoid it.
- AdBlue doesn't dilute in diesel — it separates out — so adding extra diesel won't weaken it.
- Any driving at all is to be avoided, even a short stretch down The Broadway.
- By the road, do not attempt emptying it on your own.
Get the attendants to help you move your car off the pumps if you're on a forecourt around Greenford, whether it's the Shell or elsewhere. If you are on your own drive, leave it exactly where it sits.
AdBlue in a diesel tank, and what it does there
AdBlue is made for the exhaust, not the engine. Its own reservoir holds it, and from there it is sprayed into the exhaust, and there it cleans the gas. Neither side fits the other: urea does not belong in a pump, and a pump can't deal with urea.
Fuel blends; AdBlue, once poured in, won't. The behaviour is not at all like diesel's. Heavier than diesel, it drops and collects underneath it — the same spot the pickup sucks from. Once your pump runs, the AdBlue is first to be pulled through. Before then it sits beneath the diesel, and that is how a car filled in Northolt last night and never switched on stays the simple case, as long as no one turns the key.
It does two kinds of damage from there. It attacks certain metals found in fuel components, attacking any part it touches till it is cleared from the system. And when the water goes, the urea forms crystals that clog filters and settle in narrow passages. Overnight, a car parked in Greenford with AdBlue through its pipework gets worse; where it is only in that tank, it doesn't. The water in it causes damage of its own: your high-pressure pump and the fuel injectors depend on diesel to lubricate them, and water offers them nothing.
AdBlue in a diesel: why it's frequently worse than petrol
An issue of thin fuel is what you end up with from filling a diesel with petrol at the BP. It mixes with the diesel, and while it's in the tank it does no harm; the damage comes from running the motor on it.
AdBlue in a diesel is a fault of the wrong substance altogether. It can't just be run through, since it does not burn. It doesn't stay mixed, and so it can't be thinned. And crystals and corrosion don't wash out with the next tank of fuel. That is why the flush matters more with AdBlue than with petrol, and why starting the engine "to see" costs more here than nearly anywhere else, whether your car is in West Ealing or the middle of Greenford.
With AdBlue, the good news is no distinct from petrol. Anywhere across Greater London the vehicle has stopped, an unstarted engine means the AdBlue still in the tank: the easiest bit of a fuel system to empty.
AdBlue in a diesel tank around Greenford: how it ends up there
It is not on purpose. Many cars have the AdBlue inlet beside the diesel inlet, occasionally behind a single flap, and mixing them up is easy in poor light. Usually it is never the forecourt: someone picks up a container driving home and pours it in outside the house.
It tends to take place in a few familiar ways. Rushing, outside Our Lady of the Visitation Catholic Primary School, after a warning light came on during the school run, someone tops up the vehicle. A bottle is poured in at the end of the day on a drive just off Greenford Road. Or someone unfamiliar with that flap tops up your vehicle in dim light, stopped in the car park outside Hare and Hounds.
The least familiar cars see it most — rentals, brand-new ones, company ones, and the other vehicle in a family with one of each fuels. Anywhere across Greater London, Greenford included, the mistake doesn't change, and neither does the first response: leave it off.
AdBlue in your diesel tank in Greenford, and the engine started?
Then the tank is no longer where the AdBlue is. The fuel filter and pipework have had it pulled along, and any running carries it on to the injection pump and each injector.
Rough running, smoke, dropping power, dashboard lights or stalling: each may show up, perhaps part way across Greenford or returning from Brentside High School / Celtic F.C.. Pull over when safe. Turn off. Keep it off rather than restarting it to check. Each start pulls more of that through.
If you were on the M4, under 3 miles from Greenford, come off at the next junction and stop somewhere safe instead of pressing on.
Hopping across Greenford to the car park by West London Islamic Centre & Greenford Mosque is one matter; driving for Westminster, under 10 miles away, is another, because every mile carries the AdBlue deeper in. So mileage counts. Roughly how far had it come? Tell us.
Once the motor has been started, the flush includes more, and all of it is done where your car has ended up. Very seldom does it leave long-term damage if it's caught early.
What draining AdBlue from a diesel involves in Greenford
Our engineers come to the vehicle, wherever it has stopped around Greenford: a side street close to Our Lady of the Visitation, a drive, a lay-by or a forecourt. Which fluid got in, roughly the quantity, and if your engine has turned over: our engineers check first, because those shape the job.
Next, emptying the tank on the spot takes out the polluted diesel and the AdBlue together. What remains from AdBlue will not flush out unaided, and so the whole system gets a careful flush, which counts far more here than with petrol. After that, the fuel filter: cleaned, or changed if it must be. After that fresh diesel, then a test of your car. Roughly half an hour on site is usual for most jobs when the motor hasn't run. Quiet enough to use outside a house at night, and safe on a working forecourt, our pumps are explosion-proof.
Lastly, the system is primed with clean diesel. Whether it's a parking bay outside South Greenford or a driveway in Greenford, that is where our technicians start the engine and you drive off. Our technicians make sure it runs correctly on fresh diesel before leaving. We do it all wherever the car has ended up, and it never needs to be taken to a workshop. Insurers ask for a VAT invoice and an engineer report, and you get both afterwards.

Over the UB postcode area, the vans answering AdBlue jobs in Greenford reach much of Greater London as well, Dormers Wells, Hanwell and Southall included. Assuming won't help by a border or somewhere hard to pin down; ring and ask.
Greenford is a small village, and an on-site drain suits it: whether the vehicle is on a home drive, a residential street, a car park or a forecourt, our technicians drain it where it stands, so it never needs to be shifted to us.
What AdBlue in a diesel tank costs to put right around Greenford
There is no fair single price, since the jobs are not the same. Three things shift the cost: whether the motor has been running and for how long, how much AdBlue was put in, and where your car is. That last one comes down to whether a technician can reach it safely, and an open drive is easier than a tight gap behind Visitation Parish Centre.
For that in mind, every enquiry from Greenford begins with the identical trio — which fluid went in, what quantity, whether it ran — before a quote. Once those are known, a range turns into a single fixed figure.
Before anyone sets off, you hear the price by phone. Then payment is on the day, card or by phone, with nothing in advance. Many insurance policies include misfuelling cover, and so it's worth checking yours whilst we're on the way.
