Don't Start It: AdBlue in a Diesel Tank in Cae-draw
If AdBlue has got into the diesel tank, leave your motor off then leave your ignition off. Urea mixed in water is all AdBlue is. It doesn't burn, it doesn't mix with diesel, and the harm it does starts when your fuel system pulls it in. If your engine has not run yet, AdBlue in a diesel tank is usually drained and carefully rinsed where your car sits around Cae-draw. Call 0333 366 0103 before you do anything else.
Those opening minutes: AdBlue in your diesel tank around Cae-draw
Do:
- Pull the keys out, so no one switches the ignition on.
- Near moving traffic? So put the hazard lights on.
- Hold on to the till receipt or the empty bottle, and so you can tell us what got in and roughly how much.
- Give us a postcode starting CF47 8, or whichever street lies closest, and our van finds you directly — so call wherever you stand.
Do not:
- Don't start your motor, even for a moment to shift the vehicle.
- Many diesels power their pump the instant the ignition comes on, and so keep the car off.
- Pouring in more diesel doesn't work: AdBlue settles out instead of thinning.
- Leave it where it is instead of driving it anywhere, even a short distance up Court Street.
- By the road, don't try draining it yourself.
Moving your car away from the island is a job for attendants to help with, wherever Cae-draw forecourt you are on, the Applegreen or any other. Stopped on your own drive? Then it stays exactly as it is.
What does AdBlue do in a diesel tank?
AdBlue is made for the exhaust, not your motor. Its own tank keeps it, and from there it's sprayed into the exhaust, where it cleans the gas. Nothing inside a fuel pump is designed for this fluid — and no part of it was intended to travel that way.
It does not combine. Once it is poured into the tank, AdBlue acts not at all like fuel. The intake takes fuel from the deepest part of that tank, and that's exactly where AdBlue settles: as it is denser than diesel, it sinks. The first thing the fuel system pulls through, once it runs, is the AdBlue. So a motor that had AdBlue poured in on a drive in Twynyrodyn last night, and hasn't been started since, is still the simple case: the AdBlue is lying at the bottom of the tank, and nothing has drawn it in.
From there it causes two kinds of harm. What remains once the water evaporates is urea, which forms crystals: they settle in tiny channels and block filters. Worse, it attacks some metals in the fuel system, and carries on until it's cleared out. If the AdBlue has reached the pipework, waiting till morning in Cae-draw leaves things worse. Inside your tank only, time costs nothing. Water lubricates nothing. The high-pressure pump and every injector need diesel flowing past them, so the water content damages them by itself.
Petrol or AdBlue in a diesel: why AdBlue is commonly worse
Put petrol in a diesel at the Esso and you have a fault of thin fuel. Damage only comes from driving on it. Mixed into your diesel and sitting inside that tank, it does nothing.
The trouble with AdBlue in a diesel is a completely wrong substance. Because it does not burn, running it through isn't an option. Crystals and corrosion remain through the following fill, and AdBlue splits again from the diesel, and so thinning it can't help. Hence the flush counts more, and trying the engine "to see" does more harm here than almost any other slip — in Glebeland or the centre of Cae-draw alike.
With AdBlue, the good news is no different from petrol. Emptying a tank is the simplest part on any fuel system, and without start-up, the AdBlue remains in there — anywhere across Merthyr Tydfil your vehicle has stopped.
How AdBlue ends up in a diesel tank in Cae-draw
Nobody means to do it. The AdBlue filler on many motors rests right next to your diesel filler, occasionally under the same flap, and the two caps can look alike in poor light. Usually it is not the filling station: a driver picks up a bottle driving home and pours it in at home.
It tends to occur in a couple of familiar ways. Halfway through the morning drop-off, the dashboard warns, and outside the local primary school the refill is hurried. A bottle is poured in at the end of the day on a drive just off High Street. One more version: dim light, the car park outside The Welsh Bar, and a driver using that flap for the first time.
It comes up the most in a rental, a brand-new vehicle, a company vehicle, or the spare motor in a home with both fuel types — the cars people know the least. Leave it off: that is the first step to the same slip, anywhere around Cae-draw or the remainder of Merthyr Tydfil you are.
Cae-draw: started your engine with AdBlue in the diesel tank?
In that case, the AdBlue is no longer inside the tank. It has been pulled through your filter and the fuel lines, and if your engine ran for any time, it has got to the high-pressure fuel pump and the injectors.
Expect lumpy running, exhaust smoke, falling power, warnings on your dash, or a stall — coming back from Incline bottom, perhaps, or part way across Cae-draw. Stop as soon as it is safe, switch off, and don't restart the car to check. Every start pulls more of it through.
On the M4, under 25 miles from Cae-draw, the first junction is where to leave, and anywhere safe is where to park — not carrying on.
A quick hop across Cae-draw to the car park by Technology is one thing; driving for Newport, under 25 miles away, is something else, since every mile carries the AdBlue further in. So mileage matters. Let us know about how far it had come.
Once the engine has been started, the flush includes more, and all of it is done where the vehicle has ended up. Very rarely does it leave long-term damage if it's caught early.
Draining AdBlue in a diesel around Cae-draw: what it takes
Wherever it has stopped around Cae-draw — a filling station, a layby, a driveway, a road by St Tydfil's Parish Church — the van travels to the vehicle. The work depends on three answers, which our engineers get first — what went in, the amount, and whether your motor has turned over.
The polluted diesel and the urea leave together after your tank is drained, on the spot. With AdBlue, more so than with petrol, the flush matters: the whole system is flushed all the way through because what remains will not flush away unaided. Next, the filter: cleaned, or replaced when it must be. After that clean diesel, and then a test of your car. If the engine has not run, the majority of jobs take about half an hour once our engineers are there. Our pumping gear is explosion-proof, and so a live forecourt is no issue, and it is quiet enough for a residential street late at night.
Fresh diesel goes in to bleed your system, and that's the last step. Firing it up comes next, and then you head off from where the car is parked, at Merthyr Tydfil or on a driveway around Cae-draw. Our technicians make sure it runs properly on fresh diesel before we go. Our engineers do it all wherever the car has ended up, and it never has to go to a workshop. The insurer is likely to want an engineer's report and your VAT invoice — both yours once this job is done.

AdBlue in a diesel tank in Cae-draw: the cost of fixing it
Not one single figure could be honest, since every job is different. What changes the cost is, first, whether the motor has run and for how long; then how much AdBlue was put in; and then where the car is and whether our van can reach it safely, which is easier on an open drive than in a tight gap behind The Robert and Lucy Thomas Memorial Fountain.
What went in, how much, and whether the engine ran: every Cae-draw call opens with exactly those, ahead of a quote, not after. Their answers shrink a range right down to one number.
Priced on the call before the van sets out, the job is settled that day — card or phone, no deposit. Plenty of insurance policies include misfuelling cover, so it is worth checking yours while we're on the way.
