Moorfields: AdBlue in the Diesel Tank? Leave It Off
If AdBlue has got into the diesel tank, leave your engine off and keep the ignition off. AdBlue is urea dissolved in water. Not like fuel, it neither burns nor blends, and no harm happens until your motor pulls it through. In Moorfields, AdBlue in a diesel tank caught before your motor runs usually means a drain and a thorough flush, just where the vehicle is. First, call us on 0333 366 0103.
Those opening minutes: AdBlue in the diesel tank around Moorfields
Do these:
- So nobody can switch the ignition on, pull your keys away.
- If you are anywhere close to moving traffic, put your hazards on.
- Which fluid, and roughly what quantity? Hang on to the bottle or your receipt, and we can know.
- Ring us from where you are. A postcode starting HR4 9, or the name of the nearest street, gets the van to you without a search.
Not to do:
- Not even for a second, and not to roll your car: the engine remains off.
- Your ignition stays off: on many diesels, switching it on is enough to run your pump.
- Adding more diesel does not help: AdBlue separates out rather than thinning.
- Even a short way down Shinwell Road is too far to drive the car.
- No draining it yourself, either, on the roadside.
Rolling your car off the island is a job for staff to help with, whichever Moorfields forecourt you are on, the Sainsbury's or any other. On that drive, the vehicle stays exactly where it was left.
AdBlue in a diesel tank, and what it does there
Made for your exhaust, AdBlue has no place in your engine. Its own tank keeps it, and from there it's fed into your exhaust, where it cleans the fumes. No part inside an injection pump is designed for this liquid — and no part of that was intended to travel that way.
Inside a diesel tank it acts very differently from fuel. It does not mix in. It sinks, because it's denser than diesel, and settles low where the intake draws its supply from. The first thing the system pulls through, after it runs, is the AdBlue. So a vehicle that had AdBlue poured in on a drive in Portfields last night, and has not been started since, is still the easy case: the AdBlue is lying at the bottom of the tank, and nothing has pulled it in.
From there it does two kinds of harm. As its water goes, the urea left behind crystallises, and the crystals block filters and settle in fine passages. And it's corrosive to some of the metals a fuel system is made from, and so it keeps working on the parts it gets to for as long as it stays there. Lines carrying AdBlue mean damage overnight for a vehicle sitting around Moorfields. Just inside your tank, it stays the same. And there is the water: it offers no protection to the parts that rely on it the most — the high-pressure pump and every injector.
AdBlue in a diesel: why it's often worse than petrol
Top up a diesel with petrol by mistake over at the Shell, and this problem is thinned fuel. It mixes with the diesel, and while it is inside the tank it causes no harm; the harm comes from running the motor on it.
With AdBlue in a diesel, the liquid as such is plainly the wrong one. Not burning, it can't simply be run through. Crystals and corrosion stay after the following fill, and AdBlue splits again from the diesel, and so thinning it can't help. Hence the flush counts so much, and turning your key "to see" costs more here than nearly any other mistake — in Blackmarstone or the heart of Moorfields equally.
The same good news holds as with petrol. Anywhere around Herefordshire your car has stopped, an unrun motor leaves the AdBlue still in the tank: the simplest bit of any fuel system to empty.
How AdBlue ends up in a diesel tank around Moorfields
It is not on purpose. Plenty of cars have the AdBlue inlet alongside the diesel one, now and then behind one flap, and mixing them up is easy after dark. Mostly it occurs with a bottle bought on the way home and poured in on the drive, not at the forecourt.
A few familiar ways cover the majority of them. A warning light comes on during the school run, and the top-up takes place in a hurry outside Lord Scudamore Primary Academy. A bottle is poured in at the end of the day on a drive just off Moorfield Street. Otherwise, in dim light by The Moorfield, the vehicle gets topped up by someone using that flap the first time.
It happens most in the motors motorists know least: a hire car, a new motor, a company car, or the second vehicle of a household with one diesel and one petrol. Wherever you are around Moorfields or the rest of Herefordshire, it's the same slip and the same first answer: leave it off.
AdBlue in the diesel tank in Moorfields, and your engine started?
Then that tank is no longer where the AdBlue is. It's been sucked through the filter and your lines, and if your motor ran for any time, it has reached your high-pressure pump and the injectors.
Watch for lumpy running, exhaust smoke, lost power, lights on the dash, or a cut-out — coming back from The Blackfriars Rose Gardens, perhaps, or midway across Moorfields. Stop when it is safe. Switch off. Keep it off rather than testing it again. More of it is pulled through with each start.
Moorfields lies under 15 miles from the M50; if you were on it, leave at the first junction and stop safely rather than driving on.
How far it went matters. A few hundred yards across Moorfields to the car park by The Salvation Army - Hereford Citadel Corps is a very different job from a run towards Hereford, under a mile away, with the AdBlue reaching further into the fuel system with each mile. Tell us about how far it had come.
Wherever your car came to a halt is where all of it gets done, even with more to flush once the engine has been running. When it is noticed soon, permanent damage is very uncommon.
Moorfields: how AdBlue is cleared from a diesel
A road beside TK Maxx, a driveway, a lay-by or a forecourt: anywhere the vehicle has stopped in Moorfields, our technicians travel to it. Before anything else we ask what went in, about how much, and whether your engine has been run, because those replies determine the work.
Then that tank is emptied where your car waits, so the polluted fuel and the AdBlue come out together. Residue from AdBlue will not flush out by itself, and so the whole system gets a careful flush, which counts far more here than for petrol. A test of the vehicle comes at the end, after clean diesel is added and your filter gets flushed or, if necessary, swapped. Engine not run? Then expect about half an hour on site for most jobs. Our pumping gear is explosion-proof, so a busy filling station is no issue, and it is quiet enough for a residential street late at night.
Bleeding your system with clean diesel comes last. Whether it's a parking space outside Hereford or a driveway in Moorfields, that is where our engineers start it and you head off. Before leaving, our technicians make sure it is running smoothly with new diesel in. No workshop is required at any stage, with the whole job done then and there. Insurers ask for a VAT invoice and an engineer report, and both come at the end.

What does AdBlue in a diesel tank cost to sort out around Moorfields?
Not one flat price would be fair, since every job is different. What changes the price is, firstly, whether your engine has been running and for how long; then how much AdBlue was put in; and then where your car is and whether our van can reach it safely, which is simpler on an open driveway than in a tight gap behind The Courtyard.
Which fluid went in, how much, plus if it ran: every Moorfields call begins by asking precisely that, before any figure, never after. The replies turn a range into a straight quote.
The price is given during the call, before anyone leaves; settling up happens on the day, by card or over the phone, with nothing upfront. Many insurance policies include misfuelling cover, so it's worth checking yours whilst we're on the way.
Moorfields: still beside the car?
Leaving your vehicle alone is, then, the most useful move open to you. Motor off, keys out, ignition off. Petrol in Diesel handles the remainder, across Moorfields or wherever within Herefordshire, once you call 0333 366 0103 to say it's AdBlue, roughly what quantity, and if it ran.
