AdBlue in the Diesel Tank in Barley Mow? Keep It Switched Off
Engine off, ignition off: that is how you start if AdBlue has got into the diesel tank. Chemically, AdBlue is just urea in water. The trouble starts once it's sucked through your lines — it will not burn, and it won't blend with diesel. In Barley Mow, AdBlue in a diesel tank caught before the motor runs usually means a drain and a thorough flush, just where the vehicle is. First, ring us on 0333 366 0103.
AdBlue in the diesel tank in Barley Mow: the first few minutes
Do these:
- Keys out — that way no one can switch anything on.
- Hazards on, if moving traffic is anywhere near.
- So you can tell us which fluid it was and about what quantity, save the till receipt or the empty bottle.
- Call right where you are. Say a DH3 2 postcode or the nearest street sign, and nobody has to search for you.
Do not do these:
- Shifting your car just a short way is no reason to fire up the engine.
- The ignition remains off: on many diesels, turning it on is enough to run the pump.
- Don't top up with diesel to thin it. AdBlue does not dilute in diesel; it separates out.
- Any driving at all is to be avoided, even a short stretch up Dorset Avenue.
- Draining the tank yourself by the road is not worth trying.
At a forecourt around Barley Mow, whether it is the Shell or another one, ask the staff to help you roll the car away from the petrol pump. At home, the vehicle remains just where it was left.
What does AdBlue do in a diesel tank?
The motor isn't what AdBlue is made for; your exhaust is. It goes into its own tank and is sprayed into the exhaust gas to fresh it. A fuel pump is not made to take it, and AdBlue was never intended to travel through one.
Fuel blends; AdBlue, once poured in, will not. The behaviour is not at all like fuel's. It is heavier than diesel, and so it sinks and gathers at the bottom of your tank, which is where the pickup draws fuel from. When your pump runs, the AdBlue is top of the list to go through. Before then it sits beneath the diesel, which is how a car filled in Portobello yesterday and not started stays the straightforward case, provided nobody touches your key.
It causes two kinds of harm from there. 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, so it keeps running on the parts it reaches for as long as it stays there. Lines carrying AdBlue mean damage overnight for a vehicle parked around Barley Mow. Only inside the tank, it stays the same. Then there's the water: it brings no lubrication to the components that rely on it most — the injection pump and every injector.
Why is AdBlue in a diesel regularly the bigger fault?
A fault of thinned fuel is what you end up with from fuelling a diesel with petrol from the JET. Blended through the diesel and left unused, it's no threat for now; using the engine does the harm.
AdBlue in a diesel is a different matter: not thin fuel, but no fuel at all. Because it doesn't burn, running it through isn't an option. Crystals and corrosion stay through the following tankful, and AdBlue separates again out of the diesel, so thinning it won't work. That is why the flush counts so much, and trying the engine "to see" costs more with AdBlue than almost any other slip — in Ayton or the heart of Barley Mow alike.
With AdBlue, the good news is no distinct from petrol. Anywhere across Tyne and Wear your car has come to rest, an unrun engine leaves the AdBlue yet in the reservoir: the easiest bit of a fuel system to clear.
How AdBlue ends up in a diesel tank around Barley Mow
After dark, two caps together — the AdBlue cap and the diesel one, occasionally under one flap — may look the same. Nobody means it; many layouts invite it. A container bought when driving home and poured in at home, instead of at the forecourt, is the typical story.
It tends to happen in a couple of familiar ways. Rushing, outside Barley Mow Primary School, after a warning light came on during the school run, a parent refills the vehicle. A bottle is poured in at the end of the day on a drive just off Durham Road. Otherwise, in dim light outside the pub in the village, the car is refilled by a driver opening that flap for the first time.
It comes up the most in a hire car, a brand-new motor, a company car, or the spare motor in a family with both fuels — the cars drivers use the least. Wherever you're in Barley Mow or the rest of Tyne and Wear, it is the same error and the same first answer: leave the car off.
Already started the motor with AdBlue in the diesel tank in Barley Mow?
In that case, the AdBlue is no longer in the tank. Given any running time, it goes on to the high-pressure pump and every injector, after passing through your filter and pipework.
Expect rough running, exhaust smoke, falling power, warnings on the dash, or a cut-out — coming back from Birtley Golf Club, say, or midway across Barley Mow. No starting it again to test: pull over when safe, then switch everything off. More of that is pulled through with each start.
Leave the A195(M), under a mile from Barley Mow, by the next junction and park safely, not carrying on.
Mileage counts: every mile pushes the AdBlue further into your system, and so driving for Newcastle upon Tyne, under 10 miles away, gives a much bigger job than crossing Barley Mow to the car park by Barley Mow Village Hall. Tell us roughly how far it had come.
There is more to flush once the motor has been run, and we do all of it where the vehicle has ended up. Caught soon, it very seldom leaves permanent damage.
What does an AdBlue drain on a diesel involve around Barley Mow?
Wherever it has come to rest around Barley Mow — a filling station, a layby, a drive, a street by Birtley Leisure Centre — our van comes to the vehicle. The job rests on three replies, and our engineers get first — which fluid got in, the amount, and if your engine has run.
The polluted diesel and the urea come out as one after your tank is drained, right there. A careful flush matters far more after AdBlue than with petrol, because what remains won't wash away by itself. After that, the filter: flushed, or replaced if it has to be. After that clean diesel, and then a test of your car. Most of these jobs are a half-hour visit once our technicians get there, if your engine has not run. Low-noise enough to use outside a house at night, and fine on a working forecourt, the pumps are explosion-proof.
Finally, the fuel system is primed with new diesel. Whether it's a parking space outside Chester-Le-Street or a drive in Barley Mow, that is where our technicians start the engine and you head off. Before leaving, our technicians confirm it's running smoothly with fresh diesel in. Since the job is done in its entirety where the car is, a workshop never comes into it. Insurers ask for a VAT invoice and an engineer report, and both come afterwards.

AdBlue drains across Barley Mow and Tyne and Wear
AdBlue jobs in Barley Mow are passed to vans that serve the places around it — Ouston, Rickleton plus Birtley — and much of Tyne and Wear further out, across DH postcodes. Ring and ask rather than guess when you're by a county line, or somewhere tricky to pin down.
Anywhere your vehicle stands — your driveway at home, a side street, a car park, a filling station — our technicians empty it on the spot, and there's no need to bring it to us; which suits Barley Mow, a residential suburb, well.
Barley Mow: what AdBlue in a diesel tank costs to fix
Each job is different, so no fixed quote is honest. What changes the cost is, firstly, whether your engine has run and for how long; then how much AdBlue got in; and after that where your car is and whether a technician can get to it safely, which is easier on an open drive than in a tight gap behind Pelaw Grange Stadium.
That's why each call from Barley Mow starts with the same three questions, asked before giving a figure, not after: what got in, how much, and whether it has run. Given them, the range narrows to one fixed figure.
Priced on the call before the van sets out, the job is settled that day — card or phone, nothing in advance. Many insurance policies include misfuelling cover, and so it's worth checking yours while we are on the way.
