Don't Start It: AdBlue in a Diesel Tank in Twyning
AdBlue in the diesel tank? Then keep the engine off — and the ignition as well. In plain terms, AdBlue is simply urea in water. As it is water-based, it won't burn and never combines with diesel; trouble just starts when your pump begins drawing it. A drain and a thorough flush, done where the car is around Twyning, is generally what AdBlue in a diesel tank needs — if it's caught before the motor has run. Phone 0333 366 0103 before you do anything else.
AdBlue in your diesel tank around Twyning: the first few minutes
Things to do:
- Take the keys out, so no one switches the ignition on.
- Put the hazards on if you're anywhere near moving traffic.
- The empty bottle or the till receipt shows us the product and the amount, so don't throw it out.
- The van locates you quickest with a postcode starting GL20 6, or simply the name of a street nearby, so call from the car.
Not to do:
- Not even for a second, and not to shift the car: the motor stays off.
- The ignition stays off: on many diesels, turning it on is enough to start the fuel pump.
- AdBlue doesn't dilute in diesel — it separates out — so adding more fuel will not weaken it.
- Any driving at all is to be avoided, even a short distance along Kilmore Lane.
- Beside the road, don't try emptying it yourself.
On a forecourt in Twyning, whether it's the BP or another one, ask the staff to help you push the vehicle away from the pump. If you are on your own drive, leave the car precisely where it is.
AdBlue in a diesel tank: what it does
Meant for your exhaust, AdBlue has no place in your motor. Stored in a separate tank, it is injected into the exhaust stream to treat the gases. No part in an injection pump is made for this liquid — and no part of that was meant to go through one.
Inside a diesel tank it behaves very differently from fuel. It does not mix in. It is heavier than diesel, and so it sinks and collects at the bottom of the tank, which is where the pickup draws fuel from. A car filled on a drive in Puckrup overnight and not started since is the simple one. No pump has pulled the AdBlue up so far — though once the engine runs, that is what is pulled first, directly from the bottom of the tank.
After it is drawn in, the harm comes in two forms. Crystals and corrosion. As the water evaporates, it leaves urea that hardens in filter elements and tiny passages; meanwhile, because it eats at certain metals, each part it touches keeps suffering for as long as it remains in there. Overnight, a vehicle sitting in Twyning with AdBlue in its lines gets worse; if it's just in your tank, it doesn't. Diesel protects the high-pressure pump and every injector as it passes; water offers none of that, and that is a separate kind of damage.
Why AdBlue in a diesel is regularly more significant than petrol
An issue of thinned fuel is what you get after fuelling a diesel with petrol from the Shell. Mixed into your diesel and sitting unused, it is no threat for now; running your engine does the harm.
With AdBlue in a diesel, the liquid itself is simply the wrong one. It cannot just be run through, because it does not burn. Whether your car sits in Shuthonger or the heart of Twyning, turning it over "to see" does more harm in this case than almost any other slip, and the flush matters more. The reasons: it won't remain mixed, so watering it down fails; and crystals and corrosion outlast the next fill.
The good news is the same as with petrol. Anywhere in Gloucestershire your car has stopped, an unrun engine leaves the AdBlue still inside the tank: the easiest bit of a fuel system to empty.
How does AdBlue end up in a diesel tank around Twyning?
Many cars put the AdBlue cap alongside the diesel one, now and then behind a single flap, and in dim light the two may look identical. No one means it. A container bought while heading home and poured in at home, rather than at the filling station, is the typical route.
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 Twyning School. A driver tips the bottle in outside their house, just off High Street, as the day ends. Otherwise, after dark by The Village Inn, the vehicle is topped up by a driver opening that flap for the first time.
The least familiar cars get it most — rentals, brand-new cars, fleet ones, and the spare car in a home with both fuels. Wherever you are around Twyning or the remainder of Gloucestershire, it's the same mistake and the same first answer: leave it off.
AdBlue in the diesel tank around Twyning, and the engine started?
Then the tank is no longer where the AdBlue is. The fuel filter and pipework have had it pulled through, and some running takes it on to the injection pump and each injector.
Expect lumpy running, exhaust smoke, falling power, lights on your dash, or a cut-out — coming back from The Green, perhaps, or part way across Twyning. Stop when safe. Switch off. Keep it off rather than restarting it to check. Each start pulls more of it through.
Twyning lies under a mile from the M50; if you were on it, leave by the next junction and pull up somewhere safe rather than carrying on.
A quick hop across Twyning to the car park by Twyning Village Hall is one thing; heading for Worcester, under 15 miles away, is something else, since every mile pushes the AdBlue deeper in. So mileage matters. Roughly how far it had come is worth telling us.
We do all of the cleaning where your car has come to a stop, and once your engine has run there is more of it. Very seldom does it leave permanent damage when it is spotted quickly.
What draining AdBlue from a diesel involves around Twyning
Anywhere it has stopped around Twyning — a forecourt, a lay-by, a drive, a street by Chad Well — our van travels to the vehicle. Which fluid went in, roughly the quantity, plus whether your motor has been run: our engineers check first, since those decide the job.
Next, emptying your tank right there takes out the polluted diesel and the AdBlue together. With AdBlue, far more than with petrol, the flush counts: the whole system is flushed all the way through because what remains won't flush away unaided. Clean diesel goes in once the fuel filter is cleaned — or swapped, when it needs to be — and after that the vehicle is tested. If the motor has not run, the majority of jobs take about half an hour once our engineers are there. Quiet enough to use outside a house at night, and fine on a busy forecourt, the pumps are explosion-proof.
The final step is to prime the system on clean diesel. Firing it up comes next, and then you head off from where the vehicle is parked, at Ashchurch for Tewkesbury or on a drive in Twyning. It's tested on clean diesel to confirm it runs properly before we leave. The whole job is done where the car is, so it never needs to be taken to a garage. Insurers want a VAT invoice and an engineer report, and you get both afterwards.

AdBlue drains across Gloucestershire, Twyning included
AdBlue jobs in Twyning go to vans that cover the places near it — Twyning Green, Hill End plus Church End — and much of Gloucestershire beyond, across GL postcodes. If you're close to a boundary, or somewhere hard to describe, ring and ask instead of assuming.
Twyning is a village, and an on-site drain suits it: whether the car is on a home drive, a residential street, a car park or a forecourt, we drain it where it is, and so it never needs to be moved to us.
AdBlue in a diesel tank in Twyning: the cost of fixing it
There's no honest single quote, since the jobs are not the same. Whether your engine has run, and for how long, comes first in what changes the price. How much AdBlue was put in comes next, and then the location of the vehicle, because an open driveway is easier for a technician to reach safely than a tight spot behind Saint Mary Magdalene.
For that in mind, each call from Twyning opens with the same trio — what got in, how much, whether the engine ran — before any quote. Their answers narrow the range down to one figure.
Our quote is given on the call, before a van leaves; payment happens on the day, by card or over the phone, with nothing upfront. Misfuelling cover is part of many insurance policies, so it is worth looking at yours before the van gets there.
In Twyning and still next to your car?
Not touching the car is, then, the best move open to you. Motor off, keys out, ignition off. Petrol in Diesel handles the remainder, in Twyning or anywhere within Gloucestershire, once you call 0333 366 0103 to say it's AdBlue, about what quantity, and if it ran.
