Don't Start It: AdBlue in a Diesel Tank in Galleyend
With AdBlue in your diesel tank, the ignition remains off and so does your engine. Urea dissolved in water is all AdBlue is. Unlike fuel, it neither burns nor mixes, and nothing starts till your motor pulls it through. A drain and a thorough flush, done where the car is around Galleyend, is normally what AdBlue in a diesel tank needs — if it is caught before the motor has run. First, phone us on 0333 366 0103.
Galleyend, AdBlue in your diesel tank: what to do right away
Do:
- Pull the keys out, and so no one switches your ignition on.
- Put the hazards on if you are anywhere close to moving traffic.
- The empty bottle or the till receipt shows us the product and the quantity, so do not bin it away.
- The van finds you fastest with a postcode starting CM2 8, or simply the name of a street close by, and so call from the car.
Things not to do:
- No starting the motor — not briefly, not to shift your car.
- Many diesels run their pump the instant your ignition comes on, so leave the vehicle off.
- AdBlue doesn't dilute in diesel — it separates out — so adding extra diesel won't weaken it.
- Even a short stretch down Rignals Lane is too far to drive the vehicle.
- No emptying it yourself, either, on the verge.
The staff working at any Galleyend filling station — the Texaco included — will usually help pushing it clear if you ask. If you are on your own drive, leave it precisely where it sits.
AdBlue in a diesel tank, and what it does there
AdBlue is made for your exhaust, not your motor. Its own reservoir holds it, and from there it is fed into your exhaust, and there it cleans the gas. Neither side suits the other: urea doesn't belong in a pump, and an injection pump can't deal with urea.
Inside a diesel tank it behaves very differently from fuel. It doesn't mix in. The intake takes fuel from the deepest part of your tank, and that is exactly where AdBlue settles: being heavier than diesel, it sinks. Once your system runs, the AdBlue is top of the list to be pulled through. Until then it waits beneath your diesel, and that is why a car filled in Great Baddow last night and not switched on remains the straightforward case, as long as no one turns the key.
It does two kinds of damage from there. What is left once the water evaporates is urea, which turns into crystals: they settle in narrow passages and clog filters. On top of that, it eats at certain metals in a fuel system, and keeps going till it is flushed out. A motor left standing around Galleyend with AdBlue already in its lines is worse by the morning; one with AdBlue just in its tank isn't. Water protects nothing. The high-pressure pump and each injector depend on diesel running past them, so the water part damages them in its own right.
Petrol or AdBlue in a diesel: why AdBlue is commonly worse
Petrol put into a diesel on BP's forecourt makes the fuel thin — that's the whole issue. Blended into your diesel and sitting unused, it's no threat for now; running your motor does the damage.
With AdBlue in a diesel, the liquid itself is simply the wrong one. Because it does not burn, running it through isn't an option. Deposits and corrosion remain through the following fill, and AdBlue splits again from the diesel, so thinning it can't work. That is why the flush counts more, and trying the engine "to see" does more harm here than almost any other mistake — in Little Mascalls or the heart of Galleyend alike.
The good news is the same as with petrol. Wherever in Essex the car has come to rest, an unstarted motor means the AdBlue yet inside the tank: the simplest bit of a fuel system to clear.
AdBlue in a diesel tank around Galleyend: how it ends up there
In dim light, two caps together — the AdBlue one and the diesel cap, now and then behind one flap — can look the same. Nobody intends it; many designs allow it. A bottle picked up when driving home and poured in at home, instead of at the forecourt, is the usual story.
Usually, it happens in one of a few familiar ways. Midway through the drop-off, the dashboard flags it up, and outside St Michael's Church of England Voluntary Aided Junior School the refill is hurried. Close to Brook Lane, someone pours a bottle in on that drive after work. Or the car is topped up in the car park at Seabrights Barn, in poor light, by someone who has never opened that flap before.
It comes up the most in a rental, a brand-new motor, a company vehicle, or the spare motor in a home with both fuels — the vehicles drivers use the least. Wherever across Essex, Galleyend as well, the mistake doesn't change, and nor does the first step: keep it switched off.
Galleyend: started the motor with AdBlue in the diesel tank?
Then the AdBlue has left that tank. Via the fuel filter, through the pipework, and — with any running time — into the high-pressure pump and each injector: that is where it travels.
Rough running, smoke from the exhaust, lost power, dashboard warnings or stalling: each might appear, maybe midway across Galleyend or coming back from Jubilee Park. No restarting to check: pull over once it is safe, then turn everything off. Each start pulls more of that through.
If you were on the M25, under 15 miles from Galleyend, come off at the next exit and stop somewhere sensible instead of pressing on.
Mileage matters: every mile pushes the AdBlue further into your system, and so heading for Chelmsford, under 3 miles away, gives a much bigger job than hopping across Galleyend to the car park by Old Water Pump. About how far it had come is worth telling us.
We do all of the flushing where the car has stopped, and once the motor has run there is more of it. Permanent damage is very uncommon if it is noticed soon.
What draining AdBlue from a diesel involves in Galleyend
The car remains where it is, whether that is a street near Galleywood Village sign, a drive, a layby or a filling station around Galleyend, and the van travels to it. The work rests on three replies, and our engineers get before all else — what went in, the amount, and whether the engine has turned over.
Then your tank is cleared where your car waits, and so the tainted fuel and the AdBlue come out together. Your system is purged thoroughly, which counts more with AdBlue than with petrol, since what it leaves behind does not rinse out on its own. After that, the filter: cleaned, or replaced if it must be. Then fresh diesel, then a test of the car. If the motor hasn't run, the majority of jobs take about half an hour once our technicians arrive. The pumps are explosion-proof, safe on a working forecourt and quiet enough to use outside a house after dark.
New diesel goes in to bleed your system, and that's the final step. Whether it's a parking bay outside Chelmsford or a driveway in Galleyend, that is where our engineers fire it up and you set off. Before we go, our technicians confirm it's running correctly with fresh diesel in. As the job is done in full where the vehicle is, a workshop never comes into it. Afterwards, there is paperwork for the insurer: a VAT invoice and a report from the engineer.

What AdBlue in a diesel tank costs to put right around Galleyend
There is no fair single quote, since the jobs are not the same. The price shifts first with how long, if at all, the engine has been running, and next with the amount of AdBlue that went in. After that it depends on where the vehicle is and whether a van can reach it safely, which is simpler on an open driveway than in a tight gap behind Galleywood Library.
What went in, how much, and if the engine ran: every Galleyend call opens by asking exactly that, before any quote, never afterwards. With those replies, the range narrows to one fixed number.
Our price is given on the call, before a van leaves; settling up comes on the day, by card or by phone, with nothing upfront. Many insurance policies include misfuelling cover, so it's worth checking yours while we are on the way.
