Don't Start It: AdBlue in a Diesel Tank in Burnfoot

Motor off, ignition off: that's how you begin if AdBlue has got into the diesel tank. In plain terms, AdBlue is simply urea in water. It doesn't burn, it does not mix with diesel, and the harm it does starts when your fuel system pulls it in. A drain and a thorough flush, done where the vehicle is in Burnfoot, is generally all AdBlue in a diesel tank takes — if it is caught before the motor has been run. Before anything, ring us on 0333 366 0103.

AdBlue in the diesel tank in Burnfoot: the first few minutes

Do these:

  • Take the keys out, and so no one switches your ignition on.
  • Near moving traffic? Then put the hazard lights on.
  • Hold on to the receipt or the empty bottle, so you can tell us what got in and about how much.
  • Call us from where you are. A postcode starting TD9 8, or the name of the closest street, gets our van to you without a search.

Things not to do:

  • No starting the engine — not briefly, not to shift your vehicle.
  • Turning the key to ignition alone starts the pump running on many diesels. Avoid it.
  • No more fuel added. The AdBlue won't mix, so it's wasted.
  • Any driving at all is best avoided, even a short stretch down Kenilworth Avenue.
  • Do not try to drain it yourself by the kerbside.

At a forecourt around Burnfoot, whether it is the Esso or another one, ask the attendants to help you push your car away from the petrol pump. Stopped on your own driveway? Then it stays just as it is.

AdBlue in a diesel tank: what it does

Made for the exhaust, AdBlue has no business in the engine. Its own tank keeps it, and from there it is sprayed into your exhaust, where it treats the fumes. Nothing in it is meant to pass through a fuel pump, and nothing in a fuel pump is built to handle it.

Fuel mixes; AdBlue, once tipped in, won't. Its behaviour is not at all like fuel's. The intake takes fuel from the deepest part of your tank, and that's just where AdBlue ends up: being heavier than diesel, it sinks. When your system runs, the AdBlue is top of the list to go through. Before then it waits underneath the diesel, and that is why a car topped up in Hawick yesterday and not switched on remains the straightforward case, as long as nobody touches your key.

After it's drawn in, the damage takes two forms. Crystals and corrosion. As the water dries, it strands urea that crystallises in filter elements and tiny channels; and, because it eats at some metals, every part it reaches suffers for as long as it remains inside. Lines carrying AdBlue mean damage overnight for a car sitting in Burnfoot. Only inside your tank, it stays stable. The water in it causes damage of its own: your high-pressure pump and the injectors depend on diesel to lubricate them, and water offers them nothing.

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

Put petrol in a diesel at the Morrisons and you have an issue of thin fuel. No damage comes while it sits unused, mixed into your diesel — only once the motor runs on it.

AdBlue in a diesel is a fault of the wrong substance altogether. Because it doesn't burn, running it through isn't an option. Deposits and corrosion remain through the following fill, and AdBlue separates back from your diesel, and so thinning it can't work. That is why the flush matters so much, and trying your engine "to see" costs more with AdBlue than nearly any other mistake — in Appletreehall or the centre of Burnfoot equally.

As with petrol, there's good news. Not started? Then the AdBlue sits just inside your tank, the easiest section of the entire system to clear, anywhere your car has stopped in Scottish Borders.

AdBlue in a diesel tank around Burnfoot: how it ends up there

In dim light, two caps side by side — the AdBlue one and the diesel cap, now and then behind a single flap — may appear the same. Nobody means it; plenty of designs invite it. Most of the time it happens with a bottle bought on the way home and poured in on the driveway, not at the forecourt.

The ways it takes place are few and familiar. A warning light comes on during the school run, and the top-up happens in a hurry outside the local primary school. In the evening, a container is tipped in on a drive close to Burnfoot Road. Otherwise, after dark outside Trinity Bar, the vehicle is topped up by someone using that flap for the first time.

It crops up most in a hire car, a new motor, a fleet car, or the other vehicle in a home with both fuel types — the cars drivers know least. Anywhere across Scottish Borders, Burnfoot included, the slip doesn't change, and nor does the first response: leave it off.

Already started the engine with AdBlue in the diesel tank around Burnfoot?

Then the AdBlue has left the tank. The fuel filter and pipework have had it sucked through, and any running takes it on to the injection pump and every injector.

Watch for lumpy running, exhaust smoke, falling power, warnings on your dash, or a cut-out — coming back from Brunton Park, say, or midway across Burnfoot. Pull over when it is safe. Turn off. Keep it off instead of testing it again. Every start pulls more of it through.

If you were on the A74(M), under 50 miles from Burnfoot, come off at the next exit and stop somewhere sensible instead of pressing on.

Distance counts: every mile carries the AdBlue deeper into the system, and so driving towards Carlisle, under 50 miles away, makes a much larger job than crossing Burnfoot to the car park by Burnfoot Community Hub. Tell us roughly how far it had come.

Our technicians do all of the rinsing where the car has come to a stop, and once your engine has been run there is more of it. Noticed early, it very rarely leaves lasting damage.

What clearing AdBlue from a diesel involves around Burnfoot

A street beside Hawick Elim Community Church, a driveway, a layby or a forecourt: anywhere the car has come to rest in Burnfoot, our technicians travel to it. Before anything else our engineers ask what went in, about how much, and if the engine has been run, since those answers settle this work.

On the spot, that tank is then drained, and both the polluted diesel and the urea leave at once. A careful flush matters far more with AdBlue than with petrol, since what remains will not clear out by itself. Testing your vehicle comes last, once clean diesel goes in and the fuel filter is flushed or, where necessary, swapped. If the engine hasn't run, most jobs take about half an hour once our technicians are there. Explosion-proof pumps mean a live forecourt safe to work on, and they're quiet enough not to disturb the street at night.

New diesel goes in to bleed the system, and that's the last step. Then we start the car and you set off, whether from a parking bay outside Tweedbank or a driveway around Burnfoot. The check before our engineers go is that it runs correctly on fresh diesel. The whole job is done where the vehicle is, so it never needs to go to a workshop. You receive a VAT invoice and an engineer report after that, which is what insurers ask for.

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

There is no fair single quote, since the jobs are not the same. What changes the cost is, firstly, whether the engine has run and for how long; then how much AdBlue went in; and then where the vehicle is and whether a van can get to it safely, which is simpler on an open driveway than in a tight space behind Mansfield Park.

Before any figure, not afterwards, every call from Burnfoot begins with the same three questions: the liquid, the amount, and whether the engine ran. Once those are answered, a range turns into a single firm number.

Before a van sets off, you are told our quote by phone. And payment is on the day, card or by phone, with nothing upfront. Look at your insurance while we are on the way: plenty carry misfuelling cover.
