AdBlue in the Diesel Tank in Elmsett? Keep It Switched Off

AdBlue in the diesel tank? Then leave the engine off — and your ignition too. AdBlue is urea dissolved in water. It does not burn, it does not mix with diesel, and the harm it does starts when the fuel system draws it in. If the motor has not run yet, AdBlue in a diesel tank is normally drained and carefully cleaned where the car sits around Elmsett. Before you do anything else, call 0333 366 0103.

AdBlue in the diesel tank around Elmsett: the first few minutes

To do:

  • Remove your keys, which stops anyone switching the power on.
  • Near moving traffic? Then put the hazard lights on.
  • So you can tell us which liquid it was and about how much, keep the receipt or the empty bottle.
  • Ring us from where you are. A postcode starting IP7 6, or the name of the nearest street, gets the van to you without a search.

Never:

  • No starting your engine — not for a second, not to reposition the vehicle.
  • Do not switch the ignition on. On plenty of diesels that alone runs the fuel pump.
  • Pouring in extra diesel does not help: AdBlue settles out rather than thinning.
  • Do not drive it anywhere, not even a short stretch down Garrards Road.
  • By the road, don't attempt draining it on your own.

The staff working at any Elmsett filling station — the Gulf included — will normally lend a hand pushing it aside if you ask. If you are on your own drive, leave the vehicle exactly where it sits.

AdBlue in a diesel tank: what it does

The motor is not what AdBlue is made for; the exhaust is. It goes into its own tank and is sprayed into the exhaust gas to clean it. A fuel pump is not designed to take it, and AdBlue was never supposed to go through one.

Fuel blends; AdBlue, after tipped in, won't. The behaviour is nothing like diesel's. It drops, since it is denser than diesel, and pools low where the pickup draws its supply from. Simplest of all: one that had AdBlue in Burstallhill last night and has not turned since. The liquid sits at the base of your tank, undrawn — though it will be the first thing through once your motor runs, before any diesel at all.

Two kinds of damage come 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, so it keeps running on the parts it reaches for as long as it remains there. A vehicle left standing around Elmsett with AdBlue already in its lines is worse by the morning; one with AdBlue just in its tank isn't. And there is the water: it brings no lubrication to the components that need it most — the injection pump and every injector.

Draining AdBlue from a diesel tank in Elmsett

AdBlue in a diesel: why it is regularly worse than petrol

Petrol pumped into a diesel on another forecourt nearby's forecourt makes your fuel watery — that is the whole issue. Harm only comes from running on it. Blended into the diesel and left in that tank, it causes none.

With AdBlue in a diesel, the liquid as such is simply the wrong one. It does not burn, so it can't simply be run through. Deposits and corrosion stay after the next fill, and AdBlue separates again out of the diesel, so thinning it won't work. Hence the flush matters more, and turning the key "to see" does more harm here than nearly any other slip — in Offton or the centre of Elmsett alike.

The good news is the same as with petrol. Not run? Then the AdBlue sits only inside the tank, the easiest section of the whole system to empty, wherever the vehicle has come to rest around Suffolk.

Elmsett: how AdBlue ends up in a diesel tank

After dark, two caps together — the AdBlue one and the diesel one, occasionally under one flap — can appear the same. No one means it; plenty of layouts invite it. Usually it's not the filling station: a driver buys a container driving home and pours it in outside the house.

A few familiar ways account for most cases. Halfway through the morning drop-off, the dashboard flags it up, and outside Elmsett Church of England Primary School the refill is rushed. Close to Whatfield Road, someone pours a container in on the drive in the evening. Or the car is topped up in the car park at Rose & Crown, in poor light, by someone who has never opened that flap before.

It happens most in the motors motorists know least: a hire car, a new car, a company car, or the second motor of a household with one diesel and one petrol. An identical mistake, same first response — leave it switched off — anywhere you happen to be in Elmsett or the remainder of Suffolk.

Already started the motor with AdBlue in the diesel tank in Elmsett?

Then the tank is no longer where the AdBlue is. The filter and lines have had it pulled along, and any running carries it on to the high-pressure pump and every injector.

You may see the motor running unevenly, smoking, losing power, showing warning lights or cutting out, perhaps on the way back from Borley's Wood or halfway across Elmsett. No restarting to test: stop once it is safe, then switch everything off. Each start pulls more of that through.

On the M11, under 50 miles from Elmsett, the first junction is where to leave, and anywhere safe is where to stop — not carrying on.

Hopping across Elmsett to the car park by Elmsett Methodist Church is one thing; heading towards Colchester, under 15 miles away, is another, since every mile pushes the AdBlue further in. So distance matters. Tell us roughly how far it had come.

Our engineers do all of the cleaning where the vehicle has ended up, and once your engine has been started there is more of it. Lasting damage is very uncommon if it is caught early.

What clearing AdBlue from a diesel involves around Elmsett

Our engineers come to the car, wherever it has stopped in Elmsett: a side street near Elmsett Village Sign, a drive, a lay-by or a forecourt. Which fluid went in, roughly how much, plus if the motor has turned over: our technicians check before all else, because those shape the work.

Next, draining that tank on the spot removes the contaminated diesel and the AdBlue in one go. The fuel system is purged thoroughly, which matters more with AdBlue than with petrol, since what it leaves behind doesn't rinse out on its own. The filter is flushed, or replaced where it needs to be; fresh diesel goes in; and your car is tested. If the motor has not run, the majority of jobs take about half an hour once we arrive. Our pumping gear is explosion-proof, so a busy filling station is no issue, and it is quiet enough for a residential street late at night.

Last, the system is bled with clean diesel. You set off as soon as we have fired it up, and it makes no difference whether the car is on a driveway in Elmsett or in a space by Needham Market. It is tested on fresh diesel to confirm it runs correctly before we head off. No garage is required at any point, with the entire job done on the spot. Your insurer is likely to want an engineer's report and your VAT invoice — both yours afterwards.

Elmsett and Suffolk: AdBlue drains across the area

Aldham, Flowton and Whatfield are among the towns around Elmsett that the same teams reach, along with much of Suffolk further out, throughout the IP postcode area. If you're near a border, or somewhere hard to explain, ring and ask instead of assuming.

Wherever your car stands — a drive at home, a residential street, a parking area, a filling station — our engineers drain it on the spot, and there's no need to bring it to us; that suits Elmsett, a rural village, well.

Elmsett: what AdBlue in a diesel tank costs to fix

No flat price could be honest, because every job differs. Whether the motor has run, and for how long, comes first in what moves the price. How much AdBlue got in comes next, and then the location of the car, since an open driveway is simpler for our van to get to safely than a tight space behind Tithe memorial.

Before any figure, never afterwards, every call from Elmsett opens with three checks: the fuel, the quantity, plus if it ran. With those replies, the range narrows to one fixed figure.

You get that price on the phone, before anybody sets off, and you pay on the day, by card or over the phone, with nothing upfront. While our engineer is travelling, dig out your policy: many cover misfuelling.
