AdBlue in a Diesel Tank in Larchfield? Don't Start It

With AdBlue in your diesel tank, the ignition remains off and so does your engine. In plain terms, AdBlue is just urea in water. The harm begins once it is sucked through your lines — it will not ignite, and it will not combine with diesel. If your motor hasn't run yet, AdBlue in a diesel tank is usually drained and thoroughly cleaned where your car stands around Larchfield. Before you do anything else, phone 0333 366 0103.

Those opening minutes: AdBlue in your diesel tank around Larchfield

To do:

  • Pull your keys out, and so nobody switches the ignition on.
  • Near moving traffic? Then put your hazards on.
  • The empty bottle or the receipt shows us the fluid and the quantity, so don't throw it away.
  • Our van locates you quickest with a postcode starting DG1 2, or simply the name of a street close by, so call from the spot.

Never do these:

  • Shifting the vehicle even a short way is no reason to start the engine.
  • Plenty of diesels run their fuel pump the moment your ignition goes on, and so keep the vehicle off.
  • Pouring in more diesel doesn't work: AdBlue settles out instead of thinning.
  • Even a short way up Bruce Dewar Mews is too far to drive the car.
  • Beside the road, don't attempt emptying it on your own.

Get the attendants to help you move the vehicle away from the island if you're on a forecourt around Larchfield, whether it is the Morrisons or somewhere else. On your own drive, don't touch it at all.

AdBlue in a diesel tank: what it does

The engine is not what AdBlue is made for; the exhaust is. Stored in a separate tank, it's injected into the exhaust stream to treat the fumes. Nothing in it is meant to pass through a fuel pump, and nothing in a fuel pump is built to handle it.

Poured in with your diesel, it keeps apart rather than mixing — quite different from fuel. It sinks, because it is heavier than diesel, and settles low where the pickup takes its supply from. Simplest of all: one that got AdBlue in Noblehill overnight and has not been started since. The liquid waits at the foot of the tank, undrawn — though it will be the first thing through if your motor runs, ahead of any diesel at all.

After it is pulled in, the harm comes in two forms. 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 running on the components it reaches for as long as it remains there. A car left sitting around Larchfield with AdBlue already in its lines is worse by the morning; one with AdBlue just in its tank isn't. The water in it does damage of its own: your high-pressure pump and your injectors rely on diesel to lubricate them, and water offers them nothing.

Draining AdBlue from a diesel tank in Larchfield

Why AdBlue in a diesel is commonly more major than petrol

An issue of thinned fuel is what you get after filling a diesel with petrol from the BP. It mixes with your diesel, and whilst it is inside the tank it causes no damage; the damage comes from running your motor on it.

The issue with AdBlue in a diesel is a totally unsuitable substance. Because it doesn't burn, running it through isn't an option. Crystals and corrosion stay through the next fill, and AdBlue separates back from your diesel, so watering it can't help. That is why the flush matters so much, and turning the key "to see" costs more with AdBlue than almost any other slip — in Dumfries or the heart of Larchfield equally.

The same good news applies as with petrol. If your engine has not run, the AdBlue is still inside the tank, and that tank is the simplest part of a fuel system to clear, wherever across Dumfries and Galloway the car is sitting.

How does AdBlue end up in a diesel tank in Larchfield?

It is not deliberate. Plenty of vehicles keep the AdBlue inlet alongside the diesel inlet, now and then behind a single flap, and muddling them up is easy after dark. Mostly it's never the filling station: someone picks up a bottle heading home and tips it in outside the house.

A few familiar ways account for most cases. A warning light comes on during the school run, and the top-up takes place in a hurry outside the local primary school. A driver pours the container in at home, right off Rosevale Street, as the day ends. Or someone new to that flap refills your car after dark, parked in the car park by Greens.

It crops up the most in a rental, a brand-new car, a company motor, or the spare vehicle of a family with both fuels — the cars people use least. Keep it off: that is the first step to the same mistake, wherever around Larchfield or the rest of Dumfries and Galloway you are.

Started the motor with AdBlue in the diesel tank around Larchfield?

Then that tank is no longer where the AdBlue is. Given any running time, it travels to the high-pressure pump and every injector, after passing through the fuel filter and lines.

Rough running, smoke, dropping power, dashboard warnings or cutting out: any might show up, maybe part way across Larchfield or coming back from Cresswell Park. Stop as soon as it is safe, switch off, and do not restart the car to check. Each start pulls more of it through.

On the A74(M), under 10 miles from Larchfield, the first junction is where to leave, and anywhere sensible is where to stop — not carrying on.

Every mile pushes the AdBlue further in. That's why crossing Larchfield to park beside Cresswell Community Centre and a drive of under 50 miles for Carlisle are very distinct jobs. Roughly how far had it come? Tell us.

We do all of the rinsing where your car has ended up, and once your engine has been run there is more of it. If it is caught quickly, long-term damage is very uncommon.

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

We come to the car, wherever it has stopped in Larchfield: a side street close to Dumfries Baptist Church, a drive, a lay-by or a forecourt. Which fluid got in, about how much, plus whether the engine has turned over: our technicians check before all else, since those shape the work.

Then the tank is cleared where the vehicle stands, so the polluted fuel and the AdBlue come out together. What remains from AdBlue won't flush out unaided, so the fuel system gets a careful flush, which matters far more here than for petrol. The filter is flushed, or replaced where it needs to be; fresh diesel goes in; and the vehicle is tested. If your motor hasn't run, the majority of jobs take about half an hour once we arrive. Explosion-proof pumps make a live forecourt safe to work on, and they're quiet enough to spare the street at night.

Priming the system with new diesel comes last. Starting the engine comes next, and then you head off from where your car is parked, outside Dumfries or on a drive in Larchfield. The check before we head off is that it runs properly on clean diesel. No workshop is required at any stage, with the entire job done on the spot. Insurers ask for a VAT invoice and an engineer report, and you get both afterwards.

AdBlue drains across Larchfield and Dumfries and Galloway

The vans that answer AdBlue jobs in Larchfield also cover the places about it, Milldamhead, Stoop and Greenbrae among them, and most of Dumfries and Galloway beyond, across the DG postcode area. Guessing doesn't help by a border or anywhere hard to pin down; ring and ask.

A mobile service suits Larchfield, a residential suburb: you have no need to take your car to us, because we empty it there, in a driveway, a residential street, a parking area or a forecourt.

AdBlue in a diesel tank around Larchfield: the cost of fixing it

No single price would be fair, because every job differs. Three things change the price: whether your engine has been running and for how long, how much AdBlue was put in, and where the vehicle is. That last one rests on whether a van can reach it safely, and an open driveway is simpler than a tight spot behind DG One.

For that reason, each enquiry from Larchfield begins by asking the same trio — which fluid went in, how much, if the engine ran — before a figure. Given those replies, the range narrows to one firm number.

You hear that quote on the phone, before anybody sets off, and you pay on the day, by card or over the phone, with nothing upfront. Many insurance policies include misfuelling cover, so it's worth checking yours while we are on the way.
