Don't Start It: AdBlue in a Diesel Tank in Barnfield
AdBlue in your diesel tank? Then leave your engine off — and the ignition too. In plain terms, AdBlue is simply urea in water. Unlike fuel, it neither burns nor mixes, and nothing starts till your engine sucks it through. If the engine hasn't run yet, AdBlue in a diesel tank is normally drained and carefully rinsed where your car stands around Barnfield. Call 0333 366 0103 before you do anything else.
What to do straight away, Barnfield: AdBlue in your diesel tank
Do:
- Remove the keys, which prevents someone turning the power on.
- Hazards on, if moving traffic is anywhere near.
- The empty bottle or the till receipt shows us the product and the amount, so do not throw it out.
- Call us from where you are. A postcode starting BB5 2, or the name of the closest street, brings the van to you without a search.
Things not to do:
- Moving your vehicle even a short way is no reason to start the motor.
- Turning your key to ignition alone sets your pump going on many diesels. Skip it.
- Adding more diesel does not work: AdBlue separates out rather than thinning.
- Don't drive the vehicle anywhere, not even a short stretch down Beaconsfield Street.
- Do not try to drain it yourself by the kerbside.
The attendants working at any Barnfield filling station — the Esso among them — will normally help rolling it clear if you ask. Stopped on your own driveway? Then it remains exactly where it is.
AdBlue in a diesel tank, and what it does there
Made for your exhaust, AdBlue has no place in your motor. Kept in a dedicated tank, it is squirted into the exhaust stream to treat the gases. A fuel pump isn't designed to take it, and AdBlue was never intended to travel through one.
It does not blend. Once it is poured into the tank, AdBlue behaves not at all like diesel. Heavier than diesel, it sinks and pools underneath it — the very place the intake sucks from. A motor topped up on a drive in Waterloo overnight and not started since counts as the simple case. Nothing has sucked the AdBlue up so far — though when your motor turns, that is what is pulled first, straight from the bottom of the tank.
Two kinds of damage follow from there. It eats at some metals used in fuel systems, working on any part it touches till it's removed from the system. And once the water evaporates, the urea turns into crystals that clog filters and settle in narrow channels. A vehicle left sitting around Barnfield with AdBlue already in its lines is worse by the morning; one with AdBlue only in its tank isn't. Diesel lubricates the injection pump and each injector as it passes; water gives no lubrication, which is a separate form of harm.
Why AdBlue in a diesel is often more major than petrol
Fill a diesel with petrol by mistake at the Shell, and this issue is thinned fuel. It mixes with your diesel, and whilst it's inside the tank it causes no damage; the damage comes from running the engine on it.
AdBlue in a diesel is a different problem: not thin fuel, but no fuel at all. It does not burn, so it cannot simply be run through. Crystals and corrosion remain through the following fill, and AdBlue splits back from your diesel, and so thinning it won't work. That is why the flush matters more, and turning your key "to see" costs more here than nearly any other mistake — in Scaitcliffe or the centre of Barnfield equally.
The good news is the same as with petrol. Wherever across Lancashire the car has come to rest, an unrun engine means the AdBlue yet in the tank: the easiest bit of a fuel system to empty.
Barnfield: how AdBlue ends up in a diesel tank
Nobody means to do it. The AdBlue filler on many motors sits right next to your diesel filler, occasionally under the same flap, and the two caps can look alike in poor light. A bottle bought while driving home and poured in outside the house, instead of at the filling station, is the typical route.
It tends to happen in a few familiar ways. The refill is hurried outside Accrington Benjamin Hargreaves Church of England Primary School, after your dash lit up with a warning as the kids were taken in. Someone pours the bottle in outside their house, just off Barnfield Street, as the day ends. Else, in dim light by Grants, your vehicle gets refilled by someone using that flap the first time.
It crops up most in a hire car, a new vehicle, a fleet car, or the other vehicle in a home with one of each fuels — the vehicles drivers use least. Keep it off: that is the first step to the same mistake, wherever around Barnfield or the rest of Lancashire you happen to be.
Already started the motor with AdBlue in the diesel tank in Barnfield?
Then the AdBlue has left that tank. Through the filter, through the pipework, and — given any running time — on to the high-pressure pump and each injector: that's how far it travels.
Maybe coming back from Oak Hill Park, or midway across Barnfield, the engine might run lumpy, smoke, lose power, flash the dash or cut out. No starting it again to test: stop once safe, then turn it off. With each start, more of that is pulled through.
On the M65, under 3 miles from Barnfield, the next junction is where to exit, and somewhere safe is where to park — not driving on.
How far it went counts. A couple of hundred yards across Barnfield to the car park by St Paul's, Accrington is a very different job from a run towards Preston, under 15 miles away, with the AdBlue reaching further into the system with each mile. Let us know about how far it had come.
There's more to clean out once your engine has run, and our engineers do all of it where the car has ended up. If it's noticed soon, permanent damage is very unusual.
Clearing AdBlue in a diesel around Barnfield: what it takes
Anywhere it has stopped in Barnfield — a filling station, a layby, a drive, a street by Trinity Community Church — the van travels to the car. Three replies decide the work, and so before anything else our engineers ask what got in, roughly the amount, plus whether the motor has turned over.
The contaminated diesel and the urea leave as one after the tank is emptied, right there. A full flush matters far more after AdBlue than with petrol, because residue will not clear out by itself. The fuel filter is flushed, or replaced where it needs to be; clean diesel goes in; and the vehicle is tested. Engine not run? Then count on about half an hour on site for most jobs. Our pumping gear is explosion-proof, and so a live filling station is no fault, and it is hushed enough for a residential street late at night.
Finally, your system is primed with new diesel. You head off as soon as we have started it, and it makes no difference whether the car is on a driveway in Barnfield or in a space at Accrington. Before we go, our technicians check it's running smoothly with clean diesel in. The entire job is done where the car is, so it never needs to be taken to a workshop. You get a VAT invoice and an engineer report afterwards, which is what insurers ask for.

AdBlue drains across Barnfield and Lancashire

A mobile service suits Barnfield, a residential suburb: you have no need to take the vehicle to us, since our engineers empty it on the spot, on a driveway, a side street, a parking area or a filling station.
What AdBlue in a diesel tank costs to put right around Barnfield
Every job is different, so not one fixed quote would be honest. Whether the engine has run, and for how long, comes first in what moves the cost. How much AdBlue got in comes next, and then the position of your car, since an open driveway is simpler for a technician to get to safely than a tight spot behind Abbey Street Shopping Centre.
With that reason, each call from Barnfield opens with the identical trio — what went in, what quantity, if it ran — ahead of a quote. With them, a range narrows to a single fixed figure.
The price is given during the call, before a van sets off; settling up happens on the day, by card or over the phone, and nothing upfront. Look at your policy while we're on the way: many include misfuelling cover.
Barnfield: still alongside the vehicle?
Then, the best thing to do with the vehicle is to not touch it. Engine off, keys out, ignition off. Petrol in Diesel takes over the remainder, across Barnfield or anywhere within Lancashire, once you ring 0333 366 0103 saying it was AdBlue, about what quantity, and if it ran.
