Heaviley: AdBlue in the Diesel Tank? Leave It Off

If AdBlue has got into the diesel tank, keep the engine off then leave your ignition off. In plain terms, AdBlue is just urea in water. Being water-based, it will not burn and won't blend with diesel; trouble just comes when your pump starts drawing it. Caught before the motor has run, AdBlue in a diesel tank is normally a drain and a thorough flush, done where the vehicle is in Heaviley. Before you do anything else, call 0333 366 0103.

Those opening minutes: AdBlue in your diesel tank in Heaviley

Things to do:

  • Keys out — then no one can power anything on.
  • Near moving traffic? Then put the hazard lights on.
  • The empty bottle or the receipt tells us the product and the quantity, so do not throw it out.
  • Call us from where you are. A postcode starting SK2 6, or the name of the closest street, brings our van to you without a search.

Things not to do:

  • Moving your car even a short way is no reason to start your motor.
  • The ignition stays off: on many diesels, turning it on is enough to start the fuel pump.
  • No more fuel on top. The AdBlue will not blend, so it is wasted.
  • Do not drive it anywhere, not even a short way along College Close.
  • No emptying it yourself, either, on the verge.

The attendants working at any Heaviley forecourt — the Esso among them — will usually lend a hand pushing it aside if you ask. Parked on your own driveway? Then it stays just where it is.

What does AdBlue do in a diesel tank?

Not your engine but the exhaust is where AdBlue is meant to go. Stored in a dedicated tank, it's squirted into the exhaust to treat the gases. Nothing in it is supposed to pass through a fuel pump, and nothing in a fuel pump is built to handle it.

It does not blend. Once it's poured into the tank, AdBlue behaves nothing like diesel. Heavier than diesel, it drops and pools underneath it — the same spot the pickup draws from. The first thing your fuel system pulls through, once it runs, is the AdBlue. So a car that had AdBlue poured in on a drive in Davenport last night, and hasn't been started since, is still the simple case: the AdBlue is lying at the bottom of the tank, and nothing has pulled it in.

Two kinds of damage come from there. Crystals and corrosion. As the water evaporates, it leaves urea that hardens in filters and tiny passages; meanwhile, since it eats at some metals, every part it reaches keeps suffering for as long as it stays inside. Pipes holding AdBlue mean harm by morning for a vehicle sitting around Heaviley. Just inside the tank, it stays stable. The water in it does harm of its own: the high-pressure fuel pump and your injectors rely on diesel to lubricate them, and water offers them nothing.

Draining AdBlue from a diesel tank in Heaviley

Petrol or AdBlue in a diesel: why AdBlue is regularly worse

Fill a diesel with petrol by mistake at the Shell, and this problem is thinned fuel. Harm only comes from driving on it. Mixed into the diesel and left inside the tank, it does nothing.

The trouble with AdBlue in a diesel is a completely unsuitable substance. Not burning, it can't just be run through. Deposits and corrosion stay through the next tankful, and AdBlue separates back out of the diesel, so thinning it won't help. Hence the flush matters more, and turning your key "to see" does more harm with AdBlue than nearly any other mistake — in Stockport Great Moor or the heart of Heaviley alike.

The same good news applies as with petrol. Clearing a tank is the simplest job on any fuel system, and with no start-up, the AdBlue remains in there — wherever around Greater Manchester the car sits.

AdBlue in a diesel tank in Heaviley: how it ends up there

After dark, two caps side by side — the AdBlue cap and the diesel one, occasionally behind a single flap — can look the same. Nobody intends it; plenty of layouts allow it. Mostly it's never the filling station: a driver picks up a container heading home and tips it in outside the house.

The ways it takes place are few and familiar. Halfway through the morning drop-off, the dashboard flags it up, and outside St George's Church of England Primary School the refill is rushed. Someone pours the container in at home, just off Winster Grove, as the day ends. Or the car is topped up in the car park outside Puss in Boots, in poor light, by somebody who has never opened that flap before.

It comes up the most in a hire car, a new vehicle, a company motor, or the spare car of a home with both fuels — the vehicles drivers use least. Anywhere in Greater Manchester, Heaviley included, the mistake doesn't change, and nor does the first response: keep it switched off.

AdBlue in your diesel tank around Heaviley, and your engine started?

The AdBlue has left that tank, then. With any running, it travels to the injection pump and every injector, having passed through the fuel filter and pipework.

Rough running, smoke, lost power, dashboard warnings or stalling: each may show up, maybe midway across Heaviley or returning from Hallam Coronation Garden. Stop as soon as it is safe, switch off, and don't restart the vehicle to check. Every start pulls more of it through.

Leave the M60, under 3 miles from Heaviley, at the first junction and stop somewhere safe, rather than driving on.

A quick hop across Heaviley to the car park by Compass Point is one thing; heading for Manchester, under 10 miles away, is something else, because each mile carries the AdBlue further in. So distance matters. Let us know roughly how far it had come.

Wherever the car came to a stop is where all of it gets done, even with more to rinse out after your engine has been run. When it is caught early, permanent damage is very unusual.

What does an AdBlue drain on a diesel involve in Heaviley?

We come to your car, wherever it has stopped in Heaviley: a side street close to Ukrainian Centre, a drive, a lay-by or a forecourt. The job depends on three replies, and our technicians ask for before all else — what got in, the amount, and if the motor has turned over.

Next, draining that tank right there takes out the contaminated diesel and the AdBlue together. What remains from AdBlue won't flush away by itself, so the fuel system gets a full flush, which matters far more here than with petrol. After that, the fuel filter: cleaned, or changed when it must be. Then fresh diesel, and then a test of your car. About half an hour once we arrive is typical for most jobs when the motor hasn't run. Explosion-proof pumps make a busy forecourt safe to work on, and they run quiet enough to spare the neighbours at night.

The final step is to bleed the system on clean diesel. Then our technicians start it and you head off, whether from a parking bay by Davenport or a drive around Heaviley. Before leaving, our technicians check it is running properly with new diesel in. The whole job is done where your car is, so it never needs to be taken to a garage. Insurers want a VAT invoice and an engineer report, and both come at the end.

About Heaviley

Heaviley is a suburban area in Greater Manchester, situated approximately 7 miles south of Manchester city centre. Heaviley sits at an elevation of around 91 metres, in a gently undulating landscape typical of the region. Heaviley is characterised by its predominantly semi-detached housing stock, with nearby neighbourhoods including Mile End, Cale Green, and Little Moor.

Heaviley and Greater Manchester: AdBlue drains across the area

AdBlue jobs in Heaviley go to vans that serve the places around it — Mile End, Cale Green as well as Little Moor — and much of Greater Manchester beyond, across SK postcodes. If you're near a border, or somewhere hard to describe, ring and ask rather than assuming.

A mobile service fits Heaviley, a residential suburb: there's no need to bring your car to us, since our technicians empty it there, in a driveway, a residential street, a car park or a filling station.

What does AdBlue in a diesel tank cost to sort out in Heaviley?

Because each callouts vary, a flat figure would not be fair. The cost shifts first with how long, if at all, your engine has been running, and next with the quantity of AdBlue that went in. After that it depends on where your car is and whether our van can get to it safely, which is easier on an open driveway than in a tight spot behind St George's Church.

Which fluid was put in, what quantity, and whether it ran: every Heaviley enquiry begins by asking precisely those, ahead of a figure, never afterwards. The answers turn a range into a straight quote.

Before anyone sets off, you hear our quote on the phone. And you pay on the day, card or by phone, with nothing in advance. Look at your policy while we're on the way: many include misfuelling cover.
