AdBlue in the Diesel Tank in Tinkers End? Keep It Switched Off
Motor off, ignition off: that's where you start if AdBlue has gone into the diesel tank. AdBlue is urea mixed in water. Unlike fuel, it neither ignites nor blends, and no harm starts until the engine sucks it through. In Tinkers End, AdBlue in a diesel tank caught before the engine runs usually means a drain and a thorough flush, right where your car is. Call 0333 366 0103 before you do anything else.
Your next steps straight away, Tinkers End: AdBlue in the diesel tank
Do these:
- So nobody can switch your ignition on, take the keys out.
- If you are anywhere near moving traffic, put your hazards on.
- Which fluid, and roughly what amount? Save the bottle or your receipt, and our engineers will see.
- Call right where you are. Say a MK18 3 postcode or the nearest street sign, and nobody has to search for you.
Not to do:
- Moving your vehicle just a few yards is no reason to fire up the motor.
- The ignition stays off: on lots of diesels, turning it on is enough to start the fuel pump.
- No extra fuel added. The AdBlue will not mix, and so it is pointless.
- Never drive it anywhere, not even a short distance along Missenden Close.
- Beside the road, do not try draining it yourself.
The attendants on duty at any Tinkers End forecourt — the JET among them — will usually help pushing it clear if you ask. Parked on your own drive? Then it stays exactly where it is.
AdBlue in a diesel tank: what it does
Not your engine but the exhaust is where AdBlue belongs. Stored in a separate tank, it's injected into the exhaust stream to treat the gases. Not one side fits the other: urea does not belong in an injection pump, and an injection pump cannot deal with urea.
Fuel blends; AdBlue, once poured in, won't. The behaviour is not at all like fuel's. It sinks, since it's heavier than diesel, and settles low where the pickup draws its supply from. Simplest of all: one that got AdBlue in Granborough overnight and hasn't been started since. The liquid waits at the base of that tank, untouched — but it would be first through once the engine runs, before any diesel at all.
After it's drawn in, the damage takes two forms. What is left once the water evaporates is urea, which forms crystals: they lodge in narrow passages and clog filters. On top of that, it attacks some metals in a fuel system, and carries on until it's cleared out. If the AdBlue has reached the pipework, waiting overnight around Tinkers End leaves things worse. Inside your tank only, time does nothing. Water lubricates nothing. The injection pump and each injector depend on diesel running past them, so the water part harms them in its own right.
Why AdBlue in a diesel is commonly more serious than petrol
A fault of thinned fuel is what you end up with after fuelling a diesel with petrol at the Gulf. No damage is done while it stays put, mixed into the diesel — only when the engine runs on it.
AdBlue in a diesel is a different matter: not thin fuel, yet no fuel at all. Not burning, it cannot just be run through. Whether your car is in Verney Junction or the centre of Tinkers End, firing it up "to see" costs more in this case than nearly any other slip, and the flush counts for more. Why: it won't remain mixed, and so diluting it is impossible; and crystals and corrosion outlast the following fill.
The good news is the same as with petrol. If the engine has not run, the AdBlue is still in the tank, and that tank is the easiest part of a fuel system to clear, wherever around Buckinghamshire your car is standing.
AdBlue in a diesel tank in Tinkers End: how it ends up there
In dim light, two caps side by side — the AdBlue one and the diesel cap, occasionally under a single flap — may look the same. Nobody intends it; plenty of layouts allow it. Usually it is never the forecourt: a driver picks up a container driving home and tips it in at home.
It tends to take place in a few familiar ways. Hurrying, outside Winslow Church of England School, after a warning light flashed on during the school run, a parent refills the vehicle. Near Missenden Road, a driver pours a bottle in at home in the evening. Else, after dark by The George Inn, the vehicle is topped up by someone using that flap the first time.
It takes place most in the vehicles drivers know least: a hire car, a new vehicle, a company car, or the second vehicle of a household with one diesel and one petrol. Anywhere around Buckinghamshire, Tinkers End included, the mistake doesn't change, and neither does the first response: keep it switched off.
Already started the engine with AdBlue in the diesel tank around Tinkers End?
If so, the AdBlue is no longer in your tank. It's been sucked through the fuel filter and the lines, and if your motor ran for any time, it has got to the high-pressure fuel pump and the injectors.
Expect rough running, exhaust smoke, falling power, lights on the dash, or a cut-out — coming back from Tuckey Covert, say, or midway across Tinkers End. Once you safely can, pull over then switch everything off — with no turning it on again to see. Each start pulls more of it through.
On the M1, under 15 miles from Tinkers End, the first junction is where to leave, and anywhere sensible is where to park — not carrying on.
Each mile pushes the AdBlue deeper into the system. That is why a hop across Tinkers End to park near St Laurence and a drive of under 10 miles for Milton Keynes are very distinct jobs. Tell us about how far it had come.
There's more to clean out once your engine has been run, and we do all of it where your car has ended up. Very rarely does it leave lasting damage if it is caught quickly.
What emptying AdBlue from a diesel involves in Tinkers End
The car stays put, whether that is a road near Winslow Hall, a drive, a layby or a filling station in Tinkers End, and the van travels to it. Three answers decide the work, and so before anything else our engineers ask which fluid went in, about what quantity, and if the motor has run.
Right there, that tank is then drained, and both the contaminated diesel and the urea leave as one. With AdBlue, far more than with petrol, flushing counts: the fuel system is flushed right through because residue will not wash away by itself. After that, the filter: flushed, or changed when it must be. After that clean diesel, then a test of your car. Roughly half an hour once we arrive is usual for most jobs where your motor has not run. Low-noise enough for use outside a house at night, and fine on a busy forecourt, our pumps are explosion-proof.
Last, the system is bled with clean diesel. At that point we fire it up and you set off, whether from a parking space at Bletchley or a drive around Tinkers End. Our engineers confirm it runs correctly on clean diesel before leaving. Our engineers do it all wherever the car has ended up, and it never has to go to a garage. At the end, there is paperwork for your insurer: a VAT invoice and a written report from the engineer.

What does AdBlue in a diesel tank cost to sort out around Tinkers End?
Every job differs, so not one fixed price is fair.
