Warminster: AdBlue in the Diesel Tank? Leave It Off
If AdBlue has gone into your diesel tank, leave the engine off then keep your ignition off. In plain terms, AdBlue is simply urea in water. Not like fuel, it neither ignites nor blends, and nothing starts till the motor sucks it round. Caught before the engine has been run, AdBlue in a diesel tank is generally a drain and a thorough flush, done where the vehicle is around Warminster. No step comes before calling 0333 366 0103.
What to do right now, Warminster: AdBlue in your diesel tank
To do:
- Take the keys out, and so nobody switches your ignition on.
- Near moving traffic? Then put the hazard lights on.
- The empty bottle or your receipt shows us the product and the quantity, so don't throw it out.
- The van finds you fastest with a postcode starting BA12 9, or simply the name of a street nearby, and so call from the car.
Things not to do:
- Don't start your engine, even for a moment to move your car.
- Don't switch your ignition on. On plenty of diesels that alone runs the fuel pump.
- No more fuel added. The AdBlue won't blend, so it's pointless.
- Even a short way down Market Place is too far to drive it.
- By the road, don't try emptying it on your own.
Get the attendants to help you move the vehicle off the pumps if you are at a forecourt around Warminster, whether it's the Morrisons or elsewhere. On that drive, the vehicle stays just as it is.
What AdBlue does in a diesel tank
The motor is not what AdBlue is made for; your exhaust is. It goes into its own tank and is sprayed into the exhaust gas to clean it. Nothing in it is supposed to pass through a fuel pump, and nothing in a fuel pump is made to handle it.
Inside a diesel tank it behaves very differently from fuel. It does not mix in. The pickup takes fuel from the lowest part of the tank, and that is just where AdBlue ends up: as it is denser than diesel, it sinks. Simplest of all: one that got AdBlue in Woodcock last night and has not been started since. The AdBlue waits at the base of your tank, undrawn — but it will be first through if the engine runs, ahead of any diesel at all.
It does two kinds of damage from there. It eats at some metals used in fuel components, attacking any part it reaches until it is removed from the system. And when the water goes, the urea forms crystals that clog filters and settle in tiny channels. Pipes carrying AdBlue mean damage by morning for a car parked in Warminster. Just inside that tank, it stays the same. Diesel protects the injection pump and every injector as it flows; water offers none of that, and that is a second kind of harm.
AdBlue in a diesel: why it's frequently worse than petrol
Top up a diesel with petrol in error at the Esso, and the issue is thinned fuel. It mixes with the diesel, and while it's in the tank it causes no damage; the harm comes from running the motor on it.
AdBlue in a diesel is a different matter: not thin fuel, yet no fuel at all. It does not burn, so it cannot simply be run through. Deposits and corrosion remain through the following tankful, and AdBlue splits back out of your diesel, so thinning it won't work. That is why the flush matters more, and turning the key "to see" costs more here than almost any other slip — in Henfords Marsh or the centre of Warminster equally.
With AdBlue, the good news is no distinct from petrol. Anywhere in Wiltshire the vehicle has stopped, an unstarted motor means the AdBlue yet inside the reservoir: the easiest bit of any fuel system to empty.
How does AdBlue end up in a diesel tank around Warminster?
Many cars place the AdBlue filler beside the diesel cap, occasionally behind one flap, and in dim light the two can appear the same. Nobody intends it. Usually it's never the filling station: someone buys a bottle driving home and tips it in at home.
A few familiar ways cover the majority of them. Hurrying, outside The Avenue Primary School and Children's Centre, after a warning lamp came on during the school run, a parent tops up the vehicle. Someone tips the bottle in at home, just off Weymouth Street, as the day ends. Or the vehicle is topped up in the car park at The Bath Arms, in poor light, by a person who has never opened that flap before.
The least familiar vehicles get it the most — rentals, new ones, company ones, and the spare vehicle in a home with both fuel types. Anywhere around Wiltshire, Warminster included, the slip does not change, and neither does the first step: leave it switched off.
Already started your engine with AdBlue in your diesel tank around Warminster?
Then the AdBlue has left the tank. Via the fuel filter, along the lines, and — with any running — on to the injection pump and every injector: that is where it travels.
Watch for lumpy running, smoke, falling power, warnings on the dash, or a stall — returning from Lake Pleasure Grounds, perhaps, or midway across Warminster. Stop as soon as it is safe, switch off, and don't restart the vehicle to check. With each start, more of it is pulled through.
Warminster sits under 25 miles from the M4; if you were on it, exit at the first junction and pull up safely instead of carrying on.
How far it went matters. A couple of hundred yards across Warminster to the car park by Chapel of St. Lawrence Warminster is a very different job from a run towards Bath, under 15 miles away, with the AdBlue reaching further into the fuel system with each mile. Roughly how far it had come is worth telling us.
Once the engine has run, the flush includes more, and all of it is done where your car has stopped. If it's noticed early, permanent damage is very uncommon.
What emptying AdBlue from a diesel involves around Warminster
Wherever it has come to rest around Warminster — a filling station, a layby, a driveway, a road by Warminster Library — the van travels to the vehicle. Before anything else our technicians ask what went in, about how much, and whether the engine has been run, because those replies determine the work.
Next, emptying your tank right there removes the contaminated diesel and the AdBlue together. What remains from AdBlue won't wash away by itself, and so the whole system gets a careful flush, which matters much more with urea than with petrol. Fresh diesel goes in after your filter is cleaned — or swapped, if it needs to be — and then your vehicle is tested. Engine not run? Then expect roughly half an hour once we are there for most jobs. Low-noise enough to use outside a house at night, and fine on a working forecourt, the pumps are explosion-proof.
Fresh diesel goes in to prime your system, and that's the final step. Starting it comes next, and then you set off from where the car is parked, outside the nearest station or on a driveway around Warminster. It is checked on new diesel to confirm it runs correctly before our technicians go. The entire job is done where the car is, so it never has to be taken to a workshop. You get a VAT invoice and an engineer report later on, which is what insurers ask for.

What does AdBlue in a diesel tank cost to sort out in Warminster?

That last one rests on whether our van can reach it safely, and an open driveway is easier than a tight spot behind Library and Museum.
