Horsey Down: AdBlue in the Diesel Tank? Leave It Off
AdBlue in the diesel tank? Then leave the motor off — and the ignition as well. AdBlue is urea mixed in water. Being water-based, it won't ignite and never combines with diesel; damage only comes when the pump starts pulling it. In Horsey Down, AdBlue in a diesel tank found before the motor runs usually means a drain and a thorough flush, right where the vehicle is. Phone 0333 366 0103 before you do anything else.
Those opening minutes: AdBlue in your diesel tank in Horsey Down
Do:
- So nobody can turn the ignition on, take the keys out.
- Near moving traffic? So put the hazards on.
- So you can give us which liquid it was and roughly how much, keep the receipt or the empty bottle.
- Tell us a postcode starting SN6 6, or whatever street is closest, and our van finds you straight — so call wherever you stand.
Not to do:
- Not even briefly, and not to shift your car: the motor stays off.
- The ignition remains off: on many diesels, turning it on is enough to run the pump.
- Don't top up with diesel to dilute it. AdBlue doesn't dilute in diesel; it separates out.
- Any driving at all is best avoided, including a short way along Deansfield.
- No emptying it yourself, either, at the roadside.
Moving the vehicle away from the island is a job for attendants to help with, wherever Horsey Down forecourt you are on, the Esso included. If you're on your own drive, leave it just where it sits.
What AdBlue does in a diesel tank
Made for the exhaust, AdBlue has no business in your engine. From a separate reservoir it is fed straight to the exhaust, treating what your motor lets out. Nothing inside an injection pump is made for this liquid — and no part of it was meant to travel through one.
Poured in with your diesel, it keeps apart rather than blending — entirely different from fuel. The pickup sucks fuel from the lowest part of the tank, and that's exactly where AdBlue ends up: being heavier than diesel, it sinks. The first thing your fuel system pulls through, once it runs, is the AdBlue. So a vehicle that had AdBlue poured in on a drive in Hailstone Hill last night, and has not been started since, is still the straightforward case: the AdBlue is lying at the bottom of your tank, and nothing has drawn it in.
From there it does two kinds of harm. It attacks certain metals used in fuel components, working on whatever it reaches till it is removed from your system. And when the water evaporates, the urea turns into crystals that block filters and lodge in tiny passages. Where the AdBlue is in the pipework, waiting till morning around Horsey Down makes it worse. In the tank only, waiting costs nothing. Water lubricates nothing. The injection pump and each injector depend on diesel running through them, and so the water content damages them by itself.
Petrol or AdBlue in a diesel: why AdBlue is often worse
Put petrol in a diesel at the BP and you have a problem of thin fuel. Blended into your diesel and left unused, it is no threat for now; running the motor does the damage.
The trouble with AdBlue in a diesel is a completely unsuitable substance. Since it doesn't burn, running it through is not an option. Crystals and corrosion stay after the following tankful, and AdBlue separates back out of your diesel, so thinning it won't work. Hence the flush matters so much, and turning your key "to see" does more harm here than almost any other slip — in Calcutt or the heart of Horsey Down equally.
As with petrol, there's good news. Anywhere in Wiltshire your vehicle has stopped, an unrun motor means the AdBlue yet in the reservoir: the simplest part of a fuel system to clear.
Horsey Down: how AdBlue ends up in a diesel tank
Nobody means to do it. The AdBlue filler on plenty of cars rests right next to the diesel filler, sometimes under the same flap, and the two caps can look alike in poor light. Usually it's not the filling station: a driver picks up a bottle driving home and pours it in at home.
A couple of familiar ways cover most cases. Halfway through the morning drop-off, the dashboard flags it up, and outside St Sampson's Church of England Primary School the top-up is hurried. Close to B4040, someone tips a bottle in on the drive in the evening. Or your car is topped up in the car park outside The Old Bear, in poor light, by someone who has never opened that flap before.
Hired cars, new motors, fleet vehicles, or the second vehicle in a home with one of each: the least familiar vehicles see it most. Wherever you're in Horsey Down or the remainder of Wiltshire, it's the same slip and the same first answer: leave the vehicle off.
Started the motor with AdBlue in the diesel tank around Horsey Down?
Then that tank is no longer where the AdBlue is. The fuel filter and pipework have had it sucked through, and any running carries it on to the high-pressure pump and every injector.
Expect rough running, exhaust smoke, lost power, lights on your dash, or a cut-out — coming back from Hunters Lodge Copse, perhaps, or part way across Horsey Down. Stop as soon as it is safe, switch off, and don't restart it to check. Each start pulls more of that through.
Horsey Down sits under 10 miles from the M4; if you were on it, exit by the next junction and stop safely instead of driving on.
Hopping across Horsey Down to the car park by Cricklade Bowls Club is one thing; driving towards Gloucester, under 25 miles away, is something else, because each mile carries the AdBlue deeper in. So mileage counts. About how far it had come is worth telling us.
Wherever your car came to a halt is where all of it gets done, even with more to flush after your engine has been run. Caught quickly, it very rarely leaves long-term damage.
What does an AdBlue drain on a diesel involve in Horsey Down?
Anywhere it has come to rest in Horsey Down — a forecourt, a lay-by, a drive, a road beside Cricklade Leisure Centre — the van travels to your vehicle. The work depends on three answers, which our engineers get first — which fluid got in, the quantity, and if your engine has turned over.
The contaminated diesel and the urea come out as one when your tank is emptied, on the spot. Residue from AdBlue won't flush away by itself, and so the fuel system gets a careful flush, which counts much more here than with petrol. Fresh diesel goes in once the filter is flushed — or swapped, when it needs to be — and after that your car is tested. The majority of these jobs are a half-hour visit once our engineers turn up, if the motor has not run. Explosion-proof pumps make a live forecourt safe to work on, and they run quiet enough not to disturb the street at night.
Clean diesel goes in to bleed the fuel system, and that is the final step. Whether it's a parking space by Swindon or a driveway in Horsey Down, that is where our technicians start the car and you head off. The test before our engineers head off is that it runs smoothly on fresh diesel. We do it all wherever the car has ended up, and it never needs to be taken to a workshop. Afterwards, there is the paperwork for the insurer: a VAT invoice and a report from the engineer.

Horsey Down: what AdBlue in a diesel tank costs to fix
Not one single price could be honest, because each job differs. The cost changes 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 rests on where the vehicle is and whether a van can get to it safely, which is easier on an open driveway than in a tight spot behind St. Sampson.
Which fluid went in, how much, plus whether the engine ran: every Horsey Down call opens by asking exactly those, before a quote, never afterwards. Given them, a range narrows to a single fixed number.
You get that quote by phone, before anybody heads out, and you pay on the day, by card or over the phone, with nothing upfront. Plenty of insurance policies include misfuelling cover, and so it's worth checking yours whilst we're on the way.
