AdBlue in a Diesel Tank in Thorney? Don't Start It
If AdBlue has got into your diesel tank, leave the engine off and leave the ignition off. In plain terms, AdBlue is simply urea in water. Being water-based, it won't burn and never combines with diesel; damage only comes when the pump starts pulling it. In Thorney, AdBlue in a diesel tank found before the motor runs normally comes down to a drain and a thorough flush, just where the vehicle is. Nothing comes before calling 0333 366 0103.
AdBlue in your diesel tank around Thorney: the first few minutes
Do these:
- Keys out — that way nobody can switch anything on.
- Put your hazards on if you're anywhere close to moving traffic.
- Keep the receipt or the empty bottle, so you can tell us what was put in and about how much.
- The van locates you quickest with a postcode starting PE6 0, or simply the name of a street nearby, so phone from the car.
Not to do:
- Do not start your engine, even for a moment to move the vehicle.
- Don't switch the ignition on. On many diesels that alone runs the fuel pump.
- Do not top up with diesel to thin it. AdBlue does not mix in diesel; it separates out.
- Never drive the car anywhere, not even a short way down The Causeway.
- Draining the tank yourself beside the road isn't worth trying.
The staff on duty at any Thorney filling station — the Esso included — will normally lend a hand rolling it aside if you ask. At your own drive, don't move it at all.
AdBlue in a diesel tank, and what it does there
The motor is not what AdBlue is made for; your exhaust is. Kept in a separate tank, it's squirted into the exhaust to clean the gases. Not one side fits the other: urea does not belong in a pump, and an injection pump cannot take urea.
It does not combine. Once it is poured into the tank, AdBlue acts nothing like fuel. Heavier than diesel, it drops and collects below it — the very spot the intake sucks from. A motor filled on a driveway in Eye overnight and left unstarted counts as the straightforward one. Nothing has pulled the AdBlue up yet — though when your motor turns, that's what goes first, directly from the bottom of your tank.
It causes two kinds of damage from there. Crystals and corrosion. As the water evaporates, it strands urea that crystallises in filter elements and tiny channels; meanwhile, because it eats at some metals, each part it reaches keeps suffering for as long as it remains inside. If the AdBlue is in the pipework, waiting overnight around Thorney leaves things worse. In the tank alone, waiting costs nothing. Water protects nothing. The injection pump and every injector depend on diesel flowing through them, so the water content damages them in its own right.
AdBlue in a diesel: why it's frequently worse than petrol
Petrol put into a diesel on BP's forecourt leaves your fuel watery — that's the whole problem. Harm only comes from driving on it. Mixed into the diesel and sitting inside the tank, it does nothing.
AdBlue in a diesel is an issue of the wrong substance altogether. It doesn't burn, so it cannot simply be run through. It does not stay mixed, and so it cannot be thinned. And crystals and corrosion do not wash out with the next tank of fuel. That is why the flush counts more with AdBlue than with petrol, and why starting the engine "to see" costs more here than nearly anywhere else, whether your car is in Dowsdale or the middle of Thorney.
The same good news holds as with petrol. Wherever in Cambridgeshire the car has come to rest, an unstarted engine leaves the AdBlue still inside the tank: the simplest bit of a fuel system to clear.
How AdBlue ends up in a diesel tank around Thorney
Many vehicles place the AdBlue cap beside the diesel one, now and then behind one flap, and after dark the two can appear the same. Nobody means it. It mostly occurs outside the house, from a container bought en route home, not at the filling station.
A few familiar ways cover the majority of them. A warning light comes on during the school run, and the top-up occurs in a hurry outside The Duke of Bedford Primary School. In the evening, a container is tipped in on a drive close to Wisbech Road. Otherwise, in dim light outside the pub in the village, the car gets topped up by someone opening that flap the first time.
It comes up the most in a hire car, a new motor, a company vehicle, or the other motor of a home with both fuels — the vehicles people know the least. Wherever in Cambridgeshire, Thorney included, the mistake does not change, and nor does the first step: keep it switched off.
Already started the motor with AdBlue in the diesel tank around Thorney?
If so, the AdBlue is no longer in that tank. The filter and lines have had it pulled through, and some running carries it on to the injection pump and every injector.
Perhaps returning from Thorney Park, or part way across Thorney, your motor may go rough, smoke, lose pace, flash the dash or stall. Stop when it is safe. Turn off. Leave the car off rather than restarting it to check. With each start, more of that is pulled through.
On the A1(M), under 15 miles from Thorney, the next junction is where to leave, and somewhere safe is where to stop — not carrying on.
Every mile carries the AdBlue deeper in. That is why crossing Thorney to park near St Mary & St Botolph and a drive of under 10 miles for Peterborough are such distinct jobs. Tell us roughly how far it had come.
Wherever your car came to a halt is where all of it gets done, even with more to clean out after the engine has been run. If it's noticed quickly, lasting damage is very uncommon.
What does an AdBlue drain on a diesel involve in Thorney?
The vehicle remains put, whether that is a road near Thorney Museum, a driveway, a lay-by or a forecourt around Thorney, and the van comes to it. What got in, roughly the quantity, and whether your engine has been run: our technicians check before all else, since those shape the job.
Next, draining the tank right there takes out the contaminated diesel along with the AdBlue in one go. With AdBlue, more so than with petrol, the flush matters: the whole system is cleaned right through since what remains will not wash away by itself. Next, the filter: flushed, or replaced when it must be. Then clean diesel, and then a check of your car. If your motor has not run, the majority of jobs take about half an hour once we arrive. The pumping gear is explosion-proof, so a busy filling station is no problem, and it is hushed enough for a residential street after dark.
Lastly, your system is bled with fresh diesel. You drive off as soon as our engineers have fired it up, and it makes no difference whether the vehicle is on a drive around Thorney or in a bay by Whittlesea. It's tested on fresh diesel to be sure it runs correctly before we leave. The entire job is done where the vehicle is, so it never needs to go to a workshop. Insurers ask for a VAT invoice and an engineer report, and you get both at the end.

AdBlue drains across Thorney and Cambridgeshire
Throughout the PE postcode area, the vans answering AdBlue jobs in Thorney serve most of Cambridgeshire too, Nene Terrace, North Side and Eye Green among them. Assuming won't help close to a county line or anywhere hard to describe; phone and check.
Anywhere the vehicle stands — a drive at home, a side street, a parking area, a forecourt — we empty it there, and there's no need to bring it to us; that suits Thorney, a village, well.
What AdBlue in a diesel tank costs to put right around Thorney
Since the jobs vary, a single figure wouldn't be honest. The cost moves first with how long, if at all, the motor has been running, and next with the amount of AdBlue that was put in. After that it depends on where the vehicle is and whether a technician can get to it safely, which is easier on an open drive than in a tight spot behind Thorney War Memorial.
With that reason, every enquiry from Thorney begins with the identical trio — which fluid was put in, what quantity, whether the engine ran — before any quote. Given those replies, a range narrows to a single fixed figure.
You get that price on the phone, before anyone 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 insurance: many include misfuelling.
Still beside the car in Thorney?
Then the most helpful thing you can do is nothing to the vehicle. Ignition off, motor off, keys out. Petrol in Diesel takes over the remainder, in Thorney or wherever within Cambridgeshire, after you call 0333 366 0103 saying it was AdBlue, about how big an amount, and if it ran.
