Don't Start It: AdBlue in a Diesel Tank in The Leys
If AdBlue has got into your diesel tank, leave your engine off then leave your ignition off. AdBlue is urea dissolved in water. The trouble starts once it is sucked through your lines — it won't ignite, and it will not blend with diesel. In The Leys, AdBlue in a diesel tank found before the engine runs normally means a drain and a thorough flush, right where the vehicle is. No step comes before ringing 0333 366 0103.
Those opening minutes: AdBlue in the diesel tank around The Leys
Do:
- Keys out — then nobody can power anything on.
- Put your hazards on if you are at all near moving traffic.
- So you can tell us which liquid it was and about how much, save the receipt or the empty bottle.
- Call just where you are. Quote a DE6 1 postcode or the closest street name, and nobody has to search for you.
Do not do these:
- Not even briefly, and not to roll the vehicle: the motor remains off.
- Do not switch your ignition on. On many diesels that alone runs the fuel pump.
- AdBlue does not mix in diesel — it separates out — so adding extra fuel won't thin it.
- Keep the vehicle where it is rather than driving it anywhere, even a short way down Margery Close.
- Don't try to drain the car yourself by the roadside.
On a forecourt in The Leys, whether it's the Lumbards Service Centre or another one, ask the staff to help you roll the vehicle away from the petrol pump. At your own drive, do not touch it at all.
AdBlue in a diesel tank: what it does
Not your motor but your exhaust is where AdBlue belongs. It goes into its own tank and is sprayed into the exhaust gas to fresh it. Nothing in it is meant to pass through a fuel pump, and nothing in a fuel pump is designed to handle it.
Tipped in with your diesel, it keeps separate rather than blending — quite different from fuel. It drops, since it's denser than diesel, and pools low where the intake draws its supply from. Once the system runs, the AdBlue is first to be pulled through. Until then it waits beneath the diesel, which is why a vehicle filled in Compton last night and not started remains the simple case, as long as nobody touches your key.
After it is drawn in, the damage comes in two forms. Crystals and corrosion. As the water evaporates, it leaves urea that crystallises in filters and narrow channels; meanwhile, since it eats at some metals, each part it reaches suffers for as long as it remains inside. A car left standing around The Leys with AdBlue already in its lines is worse by the morning; one with AdBlue only in its tank isn't. Diesel protects the high-pressure pump and every injector as it flows; water gives no lubrication, which is a second kind of harm.
AdBlue in a diesel: why it's commonly worse than petrol
Petrol put into a diesel on Prestons's forecourt makes the fuel thin — that is the main issue. It mixes with your diesel, and whilst it is inside that tank it causes no harm; the harm comes from running the engine on it.
The trouble with AdBlue in a diesel is a totally unsuitable substance. Because it does not burn, running it through is not an option. Crystals and corrosion remain through the following tankful, and AdBlue separates back from your diesel, and so thinning it won't help. That is why the flush counts so much, and trying your engine "to see" costs more with AdBlue than nearly any other mistake — in Clifton or the centre of The Leys equally.
As with petrol, there's good news. Never run? Then the AdBlue sits only in your tank, the simplest section of the entire system to clear, wherever your vehicle has stopped around Derbyshire.
The Leys: how AdBlue ends up in a diesel tank
Nobody means to do it. The AdBlue filler on plenty of cars rests right next to your diesel filler, at times under the same flap, and the two caps can look alike in poor light. Mostly it takes place with a bottle bought on the way home and poured in on the drive, 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 St Oswald's CofE Primary School. Close to Lodge Farm Chase, a driver pours a bottle in on that drive after work. Or a driver unfamiliar with that flap tops up your car after dark, stopped in the car park outside The Stepping Stones.
Hired motors, new cars, fleet cars, or the spare vehicle in a family with one of each: the least known vehicles see it the most. Leave it off: that's the first response to the same mistake, wherever around The Leys or the rest of Derbyshire you happen to be.
The Leys: started the engine with AdBlue in your diesel tank?
The AdBlue has left the tank, then. Through the fuel filter, along the pipework, and — with any running time — into the injection pump and every injector: that is where it travels.
Maybe returning from Highfield Road Recreation Ground, or part way across The Leys, the motor might go rough, smoke, drop power, light up your dash or stall. Stop as soon as it is safe, switch off, and don't restart it to check. More of it is pulled through with each start.
On the M1, under 25 miles from The Leys, the first junction is where to leave, and anywhere safe is where to park — not driving on.
Every mile carries the AdBlue further into your system. That is why crossing The Leys to park near Marks & Spencer and a drive of under 15 miles for Derby are such separate jobs. Let us know about how far it had come.
Wherever your car came to a halt is where all of it gets done, even with more to flush once your engine has been started. Caught quickly, it very rarely leaves permanent damage.
The Leys: how AdBlue is cleared from a diesel
The car remains put, whether that is a street beside Kingdom Hall of Jehovah's Witness, a drive, a lay-by or a forecourt in The Leys, and the van comes to it. Before anything else our technicians ask what got in, about how much, and if your motor has been run, since those answers decide the work.
Then that tank is drained where your car stands, and so the tainted fuel and the AdBlue come out together. Residue from AdBlue will not wash away by itself, and so the whole system gets a full flush, which counts far more here than with petrol. Next, the fuel filter: flushed, or changed if it must be. After that fresh diesel, then a test of your vehicle. The majority of these jobs are a half-hour job once our technicians turn up, provided the motor hasn't run. Low-noise enough for use outside a house at night, and safe on a busy forecourt, our pumps are explosion-proof.
Priming your system with fresh diesel comes last. You head off as soon as our technicians have started the engine, and it makes no difference whether the vehicle is on a drive in The Leys or in a space by Uttoxeter. Our technicians confirm it runs correctly on fresh diesel before we go. The whole job is done where the vehicle is, so it never needs to go to a garage. Insurers want a VAT invoice and an engineer report, and you get both afterwards.

What AdBlue in a diesel tank costs to put right around The Leys
Each job differs, so no single price would be honest. Whether the engine has run, and for how long, comes first in what changes the cost. How much AdBlue was put in comes next, and then the location of your car, because an open driveway is simpler for a technician to reach safely than a tight gap behind Ashbourne Leisure Centre.
Which fluid went in, what quantity, plus if it ran: each The Leys enquiry opens with precisely that, ahead of a figure, never after. Once those are known, a range turns into a single fixed number.
The quote is given during the call, before anyone leaves; settling up comes on the day, by card or over the phone, with nothing upfront. Look at your policy while we are on the way: many include misfuelling cover.
