St Augustines: AdBlue in the Diesel Tank? Leave It Off
With AdBlue in the diesel tank, the ignition remains off and so does the motor. In plain terms, AdBlue is simply urea in water. Being water-based, it will not burn and won't blend with diesel; trouble only comes once the pump begins drawing it. Caught before the engine has run, AdBlue in a diesel tank is usually a drain and a thorough flush, done where your car is around St Augustines. Phone 0333 366 0103 before you do anything else.
What to do straight away, St Augustines: AdBlue in the diesel tank
To do:
- Take your keys out, and so nobody switches your ignition on.
- If you are anywhere close to moving traffic, put your hazards on.
- So you can give us which liquid it was and about what quantity, keep your receipt or the empty bottle.
- Tell us a postcode starting S40 2, or whichever street is closest, and our van finds you straight — so call wherever you are.
Don't do these:
- No starting the engine — not briefly, not to reposition your vehicle.
- Plenty of diesels power their fuel pump the moment the ignition comes on, so leave the vehicle off.
- No extra fuel added. The AdBlue won't blend, and so it's wasted.
- Any driving at all is to be avoided, even a short stretch up Dundonald Road.
- Don't try to drain it yourself at the roadside.
Rolling the vehicle away from the pumps is a job for staff to help with, whichever St Augustines forecourt you're on, the Chesterfield Autogas Ltd or any other. On your own drive, don't touch it at all.
AdBlue in a diesel tank: what it does
The motor isn't what AdBlue is made for; your exhaust is. Kept in a separate tank, it is squirted into the exhaust to clean the gases. 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 acts really differently from fuel. It does not mix in. The intake takes fuel from the deepest part of the tank, and that's exactly where AdBlue ends up: as it is heavier than diesel, it sinks. Easiest of all: a vehicle that got AdBlue in Chesterfield overnight and hasn't turned since. The AdBlue sits at the foot of the tank, undrawn — though it will be the first thing through if your engine starts, ahead of any diesel at all.
After it is pulled in, the harm takes two forms. What remains when the water goes is urea, which turns into crystals: they lodge in tiny channels and clog filters. Worse, it attacks certain metals in a fuel system, and keeps going until it's flushed out. A car left standing in St Augustines with AdBlue already in its lines is worse by the morning; one with AdBlue only in its tank is not. Water lubricates nothing. The high-pressure pump and each injector need diesel flowing through them, and so the water part damages them in its own right.
Why AdBlue in a diesel is regularly more significant than petrol
Petrol put into a diesel on Esso's forecourt makes your fuel watery — that's the main problem. Mixed through your diesel and sitting unused, it is harmless at that stage; running the motor does the damage.
With AdBlue in a diesel, the fluid as such is simply the wrong one. It doesn't burn, and so it can't simply be run through. Crystals and corrosion remain after the following tankful, and AdBlue separates again from your diesel, and so watering it can't work. Hence the flush counts so much, and trying the engine "to see" costs more here than nearly any other slip — in Hasland or the heart of St Augustines equally.
The same good news applies as with petrol. Clearing a tank is the simplest job on any fuel system, and without start-up, the AdBlue stays in there — wherever across Derbyshire the car sits.
How does AdBlue end up in a diesel tank around St Augustines?
Nobody means to do it. The AdBlue filler on many vehicles rests right next to the diesel filler, occasionally under the same flap, and the two caps can look alike in poor light. Mostly it occurs with a bottle bought on the way home and poured in on the driveway, not at the forecourt.
The ways it happens are few and familiar. A warning light comes on during the school run, and the top-up occurs in a hurry outside Spire Junior School. In the evening, a container goes in on a driveway near Lord Roberts Road. Or your car is topped up in the car park outside birdcage., in poor light, by someone who has never opened that flap before.
It takes place most in the cars motorists know least: a hire car, a new vehicle, a company car, or the second vehicle of a household with one diesel and one petrol. Wherever across Derbyshire, St Augustines included, the mistake doesn't change, and nor does the first response: keep it switched off.
St Augustines: started your engine with AdBlue in the diesel tank?
In that case, the AdBlue is no longer in your tank. Through the filter, through the pipework, and — given any running — into the high-pressure pump and each injector: that's how far it has gone.
You may see your motor running unevenly, smoking, losing power, showing warning lights or cutting out, perhaps on the way back from Queen's Park or halfway across St Augustines. When you safely can, stop then switch it off — without turning it on again to test. With each start, more of it is pulled through.
If you were on the M1, under 5 miles from St Augustines, come off at the next junction and stop somewhere safe rather than pressing on.
Each mile pushes the AdBlue further into your system. That is why crossing St Augustines to park near Derby Road Methodist Church and a drive of under 15 miles for Sheffield are such separate jobs. Let us know roughly how far it had come.
Once the motor has been started, the flush includes more, and all of it is done where your car has ended up. Lasting damage is very rare if it's caught quickly.
What does an AdBlue drain on a diesel involve around St Augustines?
A road beside Church of the Holy Family, a driveway, a layby or a filling station: anywhere your vehicle has come to rest around St Augustines, our technicians come to it. Which fluid got in, roughly how much, plus whether the motor has been run: we check before all else, since those shape the job.
Right there, that tank is then emptied, and both the contaminated diesel and the urea leave as one. What remains from AdBlue will not flush out unaided, so the fuel system gets a full flush, which counts far more with urea than for petrol. Testing your vehicle comes at the end, after clean diesel is added and the filter gets flushed or, where needed, swapped. Most of these jobs are a half-hour visit once our technicians get there, if the motor hasn't run. The pumps are explosion-proof, safe on a busy forecourt and quiet enough to use outside a house after dark.
The last step is to prime the system on fresh diesel. Whether it is a parking space outside Chesterfield or a drive in St Augustines, that is where our engineers fire it up and you set off. The test before our technicians leave 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 paperwork for your insurer: a VAT invoice and a written report from the engineer.

AdBlue in a diesel tank around St Augustines: the cost of fixing it
Because the callouts differ, a flat price wouldn't be fair. What shifts the price is, first of all, whether the engine has run and for how long; then how much AdBlue got in; and after that where the vehicle is and whether our van can reach it safely, which is easier on an open drive than in a tight gap behind The Parish Church of Saint Augustine.
That is why every call from St Augustines starts with the same three queries, asked before giving a figure, not after: what got in, how much, and if it has run. Those answers turn a range into a straight quote.
Our price is quoted during the call, before anyone leaves; settling up happens on the day, by card or by phone, with nothing upfront. As our engineer is on the way, dig out your policy: plenty include misfuelling.
