AdBlue in the Diesel Tank in Allaston? Keep It Switched Off
AdBlue in your diesel tank? Then keep your engine off — and your ignition as well. Water with urea mixed in it: that is AdBlue. It doesn't burn, it doesn't mix with diesel, and the damage it does starts when your fuel system pulls it in. Caught before the motor has run, AdBlue in a diesel tank is usually a drain and a thorough flush, done where the vehicle is around Allaston. Before you do anything else, phone 0333 366 0103.
Those opening minutes: AdBlue in your diesel tank around Allaston
Do:
- Take the keys out, so no one switches the ignition on.
- Near moving traffic? So put your hazards on.
- Which product, and about what amount? Hang on to the bottle or your receipt, and our technicians can see.
- Our van locates you fastest with a postcode starting GL15 5, or simply the name of a street close by, and so call from the spot.
Not to do:
- Don't start the engine, even for a moment to move the car.
- Many diesels power their fuel pump the instant the ignition goes on, and so keep the vehicle off.
- Adding more diesel doesn't work: AdBlue separates out rather than blending.
- Even a short distance down Windsor Drive is too far to drive it.
- Do not try to drain the car yourself by the roadside.
The attendants working at any Allaston filling station — the Co-op among them — will normally lend a hand pushing it aside if you ask. If you're on your own drive, leave the vehicle just where it is.
AdBlue in a diesel tank: what it does
AdBlue is made for your exhaust, not the motor. Its own reservoir keeps it, and from there it is fed into the exhaust, where it cleans the gas. Neither side suits the other: urea doesn't belong in a pump, and a pump cannot take urea.
Fuel blends; AdBlue, after tipped in, won't. Its behaviour is not at all like diesel's. The pickup takes fuel from the lowest part of your tank, and that is exactly where AdBlue settles: being denser than diesel, it sinks. The first thing your fuel system pulls through, once it runs, is the AdBlue. So a motor that had AdBlue poured in on a drive in Oldcroft last night, and hasn't been started since, is still the straightforward case: the AdBlue is lying at the bottom of your tank, and nothing has pulled it in.
From there it does two kinds of damage. It eats at certain metals found in fuel systems, working on any part it touches till it's cleared from the system. And when the water evaporates, the urea forms crystals that block filters and settle in tiny channels. By daybreak, a car parked in Allaston with AdBlue through its pipework grows worse; where it's just in your tank, nothing changes. Diesel protects the injection pump and every injector as it passes; water offers none of that, and that is a second kind of harm.
Why AdBlue in a diesel is frequently more major than petrol
Put petrol in a diesel at the Tesco and you have an issue of thin fuel. Damage only comes from running on it. Blended into the diesel and sitting inside the tank, it causes nothing.
With AdBlue in a diesel, the liquid itself is plainly the wrong one. It does not burn, and so it cannot simply be run through. Deposits and corrosion remain after the next tankful, and AdBlue splits again from your diesel, so thinning it can't help. That is why the flush counts more, and turning the key "to see" costs more with AdBlue than almost any other slip — in Newerne or the centre of Allaston equally.
With AdBlue, the good news is no separate from petrol. If your engine has not run, the AdBlue is still inside the tank, and your tank is the simplest part of a fuel system to clear, wherever across Gloucestershire the car is sitting.
Allaston: how AdBlue ends up in a diesel tank
No one means to do it. The AdBlue filler on many 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.
Mostly, it happens in one of a few familiar ways. Rushing, outside Primrose Hill Church of England Primary Academy, after a warning light came on during the school run, someone refills the vehicle. In the evening, a bottle goes in on a drive near The Croft. Or your car is topped up in the car park at The Greyhound, in poor light, by a person who has never opened that flap before.
It crops up most in a hire car, a brand-new vehicle, a company car, or the spare car of a home with both fuel types — the cars drivers know the least. Wherever you are in Allaston or the remainder of Gloucestershire, it's the same slip and the same first answer: leave it off.
Already started the engine with AdBlue in your diesel tank around Allaston?
Then the AdBlue has left that tank. The filter and pipework have had it pulled along, and some running time carries it on to the injection pump and every injector.
Expect lumpy running, exhaust smoke, lost power, lights on your dash, or a stall — returning from Ten Acre Wood, say, or part way across Allaston. No restarting to test: stop when safe, then turn everything off. More of that is pulled through with each start.
Exit the M5, under 10 miles from Allaston, at the first junction and park safely, not carrying on.
A quick hop across Allaston to the car park by Holy Trinity is one matter; driving towards Gloucester, under 15 miles away, is another, because every mile carries the AdBlue deeper in. So mileage matters. Approximately how far had it come? Tell us.
Once the motor has been run, the flush takes in more, and all of it is done where your car has come to a stop. If it is caught quickly, lasting damage is very unusual.
Allaston: how AdBlue is drained from a diesel
The car stays put, whether that's a road near Dean Forest Railway Museum, a driveway, a lay-by or a forecourt in Allaston, and our van comes to it. Before anything else we ask what went in, roughly how much, and if the motor has run, since those answers settle the work.
On the spot, your tank is then drained, and all of the contaminated diesel and the urea leave at once. Your system is purged thoroughly, which counts more with AdBlue than with petrol, because what it leaves behind does not rinse out on its own. The fuel filter is cleaned, or replaced where it needs to be; clean diesel goes in; and the car is tested. Engine not run? In that case count on roughly half an hour once we are there for most jobs. The pumps are explosion-proof, safe on a busy forecourt and quiet enough to use outside a house after dark.
Finally, the system is primed with fresh diesel. Starting it comes next, and then you head off from where the car is parked, at Lydney or on a drive in Allaston. We confirm it runs properly on clean diesel before we go. We do it all wherever the vehicle has stopped, and it never has to go to a garage. The insurer will want an engineer's report and your VAT invoice — each handed over afterwards.

What does AdBlue in a diesel tank cost to sort out in Allaston?
Since the callouts differ, a single figure would not be fair. What shifts the cost is, firstly, whether the engine has run and for how long; then how much AdBlue was put in; and after that where the car is and whether a technician can reach it safely, which is simpler on an open drive than in a tight gap behind Saint Joseph.
That's why each call from Allaston starts with the same three queries, asked before giving a figure, not after: what got in, how much, and whether it's run. The replies turn a range into a straight price.
You get that price on the phone, before anybody sets off, and you pay on the day, by card or by phone, with nothing upfront. Misfuelling cover is part of many insurance policies, so it is worth looking at yours before the van arrives.
