Don't Start It: AdBlue in a Diesel Tank in High Littleton
AdBlue in the diesel tank? Then keep the engine off — and the ignition as well. In plain terms, AdBlue is just urea in water. Unlike fuel, it neither burns nor mixes, and no harm happens till your engine sucks it through. In High Littleton, AdBlue in a diesel tank found before your motor runs usually means a drain and a thorough flush, just where the car is. First, ring us on 0333 366 0103.
High Littleton, AdBlue in your diesel tank: what to do at once
To do:
- Take the keys out, so nobody switches your ignition on.
- If you're anywhere near moving traffic, put the hazards on.
- Which fluid, and roughly what amount? Save the bottle or your receipt, and our technicians can know.
- Tell us a postcode starting BS39 6, or whichever street lies nearest, and our van reaches you directly — so call from wherever you stand.
Things not to do:
- No starting the motor — not briefly, not to shift your vehicle.
- Do not switch your ignition on. On plenty of diesels that alone runs the fuel pump.
- Pouring in extra diesel does not work: AdBlue settles out rather than blending.
- Any driving at all is to be avoided, even a short distance up Greyfield Road.
- Beside the road, do not attempt emptying it yourself.
The staff on duty at any High Littleton forecourt — the Murco included — will normally lend a hand pushing it clear if you ask. If you are on your own drive, leave the car just where it stands.
AdBlue in a diesel tank, and what it does there
Meant for the exhaust, AdBlue has no place in the motor. It goes into its own tank and is sprayed into your exhaust gas to clean it. Nothing in it is meant to pass through a fuel pump, and nothing in a fuel pump is made to handle it.
Poured in with your diesel, it keeps separate rather than blending — entirely different from fuel. It's heavier than diesel, so it sinks and collects at the bottom of your tank, which is where the pickup pulls fuel from. Simplest of all: a vehicle that had AdBlue in Amesbury last night and hasn't turned since. The AdBlue sits at the foot of your tank, untouched — though it would be first through once your motor starts, ahead of any diesel at all.
From there it does two kinds of damage. Crystals and corrosion. As the water dries, it strands urea that crystallises in filter elements and tiny passages; meanwhile, since it attacks certain metals, every part it reaches suffers for as long as it remains inside. If the AdBlue is in the pipework, waiting overnight in High Littleton leaves it worse. In that tank alone, time costs nothing. Water lubricates nothing. The high-pressure pump and each injector depend on diesel flowing past them, so the water content damages them by itself.
Why AdBlue in a diesel is frequently more major than petrol
A problem of thin fuel is what you end up with from filling a diesel with petrol at the Murco Fual. Blended into your diesel and left unused, it's harmless at that stage; running your motor does the damage.
With AdBlue in a diesel, the liquid itself is plainly the wrong one. Because it doesn't burn, running it through is not an option. Whether your car is in Cross Ways or the centre of High Littleton, firing it up "to see" costs more in this case than almost any other mistake, and the flush matters more. Why: it will not remain mixed, and so watering it down is impossible; and deposits and corrosion outlast the next tankful.
As with petrol, there's good news. Wherever across Somerset the car has stopped, an unstarted motor means the AdBlue still inside the reservoir: the simplest bit of any fuel system to empty.
How does AdBlue end up in a diesel tank around High Littleton?
Plenty of motors put the AdBlue filler alongside the diesel cap, now and then under one flap, and in dim light the two may look identical. Nobody intends it. Mostly it happens with a bottle bought on the way home and poured in on the drive, not at the pump.
The ways it takes place are few and familiar. A warning light comes on during the school run, and the top-up takes place in a hurry outside High Littleton CofE VC Primary School. Near Eastover Road, someone tips a container in on that drive in the evening. Or the car is topped up in the car park outside Star Inn, in poor light, by a person who has never opened that flap before.
It comes up most in a rental, a brand-new motor, a company motor, or the other motor in a family with both fuels — the vehicles people know the least. Wherever across Somerset, High Littleton as well, the slip does not change, and nor does the first response: keep it off.
High Littleton: started the motor with AdBlue in your diesel tank?
Then the AdBlue has left that tank. It's been sucked through your filter and your lines, and if your engine ran for any time, it has got to your high-pressure pump and the injectors.
Watch for rough running, exhaust smoke, falling power, warnings on the dash, or a stall — returning from High Littleton Recreation Ground, say, or midway across High Littleton. Stop as soon as it is safe, switch off, and do not restart the vehicle to check. More of that is pulled through with each start.
High Littleton lies under 15 miles from the M32; if you were on it, leave by the next junction and stop safely rather than carrying on.
Mileage counts: each mile pushes the AdBlue deeper into the system, and so driving towards Bath, under 10 miles away, gives a much larger job than hopping across High Littleton to the car park by High Littleton Scout Hall. Let us know about how far it had come.
There's more to clean out once the motor has run, and we do all of it where your car has come to a stop. When it is spotted quickly, lasting damage is very rare.
High Littleton: how AdBlue is cleared from a diesel
The car remains put, whether that is a street beside Holy Trinity, a driveway, a layby or a forecourt around High Littleton, and our van comes to it. The work rests on three answers, and our engineers ask for before all else — what got in, the quantity, and if your motor has turned over.
Then the tank is drained where your car waits, and so the contaminated fuel and the AdBlue come out together. What remains from AdBlue will not flush out unaided, so the whole system gets a full flush, which counts far more with urea than for petrol. A test of the car comes last, after fresh diesel goes in and the fuel filter is cleaned or, if needed, replaced. The majority of these jobs are a half-hour visit once we turn up, if the engine has not run. Explosion-proof pumps make a busy forecourt safe to work on, and they run quiet enough to spare the street at night.
Lastly, your system is primed with fresh diesel. Firing it up comes next, and then you set off from where your car is parked, at Keynsham or on a driveway around High Littleton. Our technicians confirm it runs smoothly on new diesel before we leave. Our engineers do it all wherever your car has stopped, and it never needs to be taken to a garage. You receive a VAT invoice and an engineer report after that, which is what insurers want.

AdBlue drains across Somerset, High Littleton included

A mobile service fits High Littleton, a rural village: you have no need to bring your car to us, because our technicians drain it there, on a driveway, a side street, a parking area or a forecourt.
High Littleton: what AdBlue in a diesel tank costs to fix
Not one flat price could be fair, because each job differs. Three things change the price: whether your engine has been running and for how long, how much AdBlue got in, and where the car is. That last one comes down to whether our van can get to it safely, and an open driveway is easier than a tight gap behind Holy Trinity Church Hall.
What was put in, what quantity, and if the engine ran: every High Littleton enquiry begins with exactly those, before any figure, never afterwards. When those are answered, a range turns into one firm number.
Quoted on the call before the van sets out, the job is paid for that day — card or phone, nothing in advance. Misfuelling cover is part of many insurance policies, so it pays to look at yours before the van arrives.
