AdBlue in the Diesel Tank in Smithy Green? Keep It Switched Off

Engine off, ignition off: that is where you start if AdBlue has got into the diesel tank. AdBlue is urea mixed in water. It does not burn, it doesn't mix with diesel, and the harm it does starts when the fuel system draws it in. A drain and a thorough flush, done where the car is around Smithy Green, is usually what AdBlue in a diesel tank needs — if it is caught before the motor has been run. Before you do anything else, call 0333 366 0103.

Smithy Green, AdBlue in your diesel tank: what to do straight away

To do:

  • Pull the keys out, and so nobody switches the ignition on.
  • If you are at all close to moving traffic, put your hazards on.
  • The empty bottle or your receipt shows us the fluid and the amount, and so do not throw it away.
  • Ring just where you are. Say a SK8 7 postcode or the closest street sign, and no one has to hunt for you.

Do not do these:

  • No starting the motor — not for a second, not to reposition your car.
  • Many diesels run their fuel pump the moment the ignition comes on, and so keep the vehicle off.
  • AdBlue doesn't dilute in diesel — it separates out — so adding extra diesel won't thin it.
  • Any driving at all is to be avoided, including a short stretch down Granby Road.
  • Do not try to drain the vehicle yourself by the kerbside.

The attendants working at any Smithy Green forecourt — the BP included — will normally help rolling it aside if you ask. At home, the car stays exactly as it was left.

AdBlue in a diesel tank, and what it does there

Not the motor but your exhaust is where AdBlue belongs. Its own reservoir holds it, and from there it's sprayed into the exhaust, where it treats the gas. Neither side suits the other: urea doesn't belong in a pump, and a pump can't take urea.

Poured in with your diesel, it keeps separate instead of mixing — entirely different from fuel. Heavier than diesel, it sinks and collects below it — the same place the intake draws from. The first thing your fuel system pulls through, after it runs, is the AdBlue. So a vehicle that had AdBlue poured in on a drive in Kitts Moss last night, and hasn't been started since, is still the straightforward case: the AdBlue is lying at the bottom of that tank, and nothing has sucked it in.

Two kinds of harm follow from there. As its water goes, the urea left behind crystallises, and the crystals block filters and settle in fine passages. And it is corrosive to some of the metals a fuel system is made from, and so it keeps labouring on the components it reaches for as long as it remains there. Lines carrying AdBlue spell harm by morning for a car parked around Smithy Green. Only inside the tank, it stays the same. Water lubricates nothing. The injection pump and each injector need diesel running past them, and so the water content harms them by itself.

Draining AdBlue from a diesel tank in Smithy Green

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

Fill a diesel with petrol by mistake over at the Shell, and this problem is thinned fuel. Blended into your diesel and left unused, it's no threat at that stage; using your engine is the damage.

AdBlue in a diesel is an issue of the wrong substance altogether. Not burning, it cannot just be run through. Nor can it be thinned, since it splits back out — and the following fill won't clear away crystals or corrosion. So the flush counts for more here, and turning the key "to see", in the heart of Smithy Green or out in Pownall Green, costs more than nearly any other error.

The good news is the same as with petrol. Emptying a tank is the easiest part on a fuel system, and without running, the AdBlue remains in it — wherever in Greater Manchester the vehicle sits.

How does AdBlue end up in a diesel tank in Smithy Green?

Plenty of motors put the AdBlue filler beside the diesel one, occasionally behind one flap, and after dark the two can appear the same. Nobody intends it. Mostly it occurs with a bottle bought on the way home and poured in on the drive, not at the forecourt.

Mostly, it takes place in one of a couple of familiar ways. The refill is hurried outside Thorn Grove Primary School, because the dash lit up with a warning while the kids were taken off. Close to Wood's Lane, a driver tips a container in on the drive in the evening. Else, after dark by The Church Inn, your car is topped up by someone using that flap for the first time.

It occurs most in the cars people know least: a hire car, a new vehicle, a company car, or the second motor of a household with one diesel and one petrol. An identical mistake, an identical first step — leave it off — anywhere you are around Smithy Green or the rest of Greater Manchester.

Smithy Green: started your engine with AdBlue in your diesel tank?

The AdBlue has left your tank, then. Given any running, it travels to the injection pump and every injector, after passing via your filter and pipework.

Maybe coming back from Thorn Grove Park, or midway across Smithy Green, your motor might go lumpy, smoke, drop pace, flash the dash or stall. No starting it again to check: stop once safe, then switch it off. Every start pulls more of it through.

Smithy Green sits under 3 miles from the Roscoe's Spur; if you were on it, exit at the first junction and pull up somewhere safe instead of carrying on.

Hopping across Smithy Green to the car park by Cheadle Hulme Institute is one thing; driving for Manchester, under 10 miles away, is another, since each mile carries the AdBlue further in. So mileage matters. Tell us about how far it had come.

Once your engine has been run, the flush includes more, and all of it is done where the car has come to a stop. If it's caught early, long-term damage is very uncommon.

What does an AdBlue drain on a diesel involve around Smithy Green?

Wherever it has stopped in Smithy Green — a filling station, a lay-by, a drive, a road beside Wolfgang Webster Gallery — our van comes to your car. Which fluid was put in, roughly the quantity, and if the motor has turned over: our engineers check before all else, because those shape the work.

On the spot, the tank is then emptied, and both the polluted diesel and the urea leave as one. With AdBlue, more so than with petrol, the flush counts: the fuel system is flushed all the way through since what remains will not wash out unaided. Next, your filter: flushed, or changed if it must be. After that fresh diesel, and then a test of the car. If your motor hasn't run, most jobs take about half an hour once our technicians arrive. Our equipment is explosion-proof, so a busy forecourt is no fault, and it is quiet enough for a residential street after dark.

Last, the fuel system is bled with new diesel. Whether it is a parking bay by Cheadle Hulme or a drive around Smithy Green, that is where our engineers start the car and you drive off. It is checked on fresh diesel to be sure it runs properly before our technicians go. Our technicians do it all wherever the car has ended up, and it never needs to go to a workshop. You receive a VAT invoice and an engineer report later on, which is what insurers ask for.

AdBlue drains across Smithy Green and Greater Manchester

Our vans that answer AdBlue calls around Smithy Green also cover the places about it, Bramhall Park, Gillbent and Cheadle Hulme among them, and most of Greater Manchester beyond, across the SK postcode area. Near a border, or somewhere awkward to explain? Asking beats assuming, so phone.

Smithy Green is a residential suburb, and a call-out drain suits it: whether your car is on a home drive, a residential street, a car park or a forecourt, our engineers drain it where it sits, so it never needs to be moved to us.

Smithy Green: what AdBlue in a diesel tank costs to fix

Each job is different, and so no single quote is honest. Whether the motor has been running, and for how long, comes first in what changes the cost. How much AdBlue was put in comes next, and then the location of your car, since an open driveway is easier for our van to reach safely than a tight gap behind All Saints' Parish Rooms.

With that reason, each enquiry from Smithy Green opens by asking the same trio — what was put in, what quantity, if the engine ran — before a figure. The replies turn a range into a straight quote.

Priced on the call before the engineer heads out, the job is settled on the day — card or phone, no deposit. Plenty of insurance policies include misfuelling cover, and so it is worth checking yours while we're on the way.
