AdBlue in a Diesel Tank in Old Treowen? Don't Start It
If AdBlue has gone into your diesel tank, leave the engine off then keep your ignition off. Chemically, AdBlue is just urea in water. As it is water-based, it won't ignite and never combines with diesel; damage only starts once the pump starts pulling it. Caught before your motor has run, AdBlue in a diesel tank is usually a drain and a thorough flush, done where your car is around Old Treowen. Call 0333 366 0103 before you do anything else.
Your next steps straight away, Old Treowen: AdBlue in your diesel tank
To do:
- So nobody can turn the ignition on, take the keys away.
- Hazards on, if moving traffic is at all near.
- The empty bottle or the till receipt shows us the fluid and the quantity, and so do not bin it out.
- Call us from where you are. A postcode starting NP11 3, or the name of the nearest street, brings our van to you without a search.
Do not:
- No starting your motor — not briefly, not to shift your car.
- Your ignition stays off: on lots of diesels, switching it on is enough to run your pump.
- Don't top up with diesel to dilute it. AdBlue doesn't dilute in diesel; it separates out.
- Leave the vehicle where it is instead of driving it anywhere, even a short distance up Pen-y-Lan Terrace.
- Draining your tank on your own beside the road isn't one to try.
The staff working at any Old Treowen forecourt — the Texaco included — will normally lend a hand pushing it clear if you ask. On your own drive, don't touch it at all.
AdBlue in a diesel tank: what it does
The engine isn't what AdBlue is made for; your exhaust is. It goes into its own tank and is sprayed into the exhaust gas to clean it. Neither side fits the other: urea doesn't belong in an injection pump, and an injection pump cannot deal with urea.
It doesn't combine. Once it's tipped into a tank of diesel, AdBlue acts not at all like diesel. The pickup takes fuel from the deepest part of your tank, and that's just where AdBlue ends up: as it is denser than diesel, it sinks. Once the pump runs, the AdBlue is first to go through. Until then it sits beneath your diesel, which is how a car filled in Treowen last night and not started stays the simple case, provided nobody turns the key.
From there it does two kinds of harm. What remains when the water goes is urea, which turns into crystals: they settle in tiny passages and block filters. Worse, it eats at some metals in the fuel system, and keeps going till it is flushed out. A motor left sitting around Old Treowen with AdBlue already in its lines is worse by the morning; one with AdBlue only in its tank isn't. Then there's the water: it offers no lubrication to the components that rely on it the most — the injection pump and every injector.
Petrol or AdBlue in a diesel: why AdBlue is commonly worse
A problem of thinned fuel is what you end up with from filling a diesel with petrol from the another forecourt nearby. Damage just comes from driving on it. Mixed into your diesel and left inside the tank, it does none.
AdBlue in a diesel is another problem: not thin fuel, but no fuel at all. Because it doesn't burn, running it through is not an option. Whether the vehicle is in Cwm-dows or the heart of Old Treowen, turning it over "to see" costs more with AdBlue than nearly any other slip, and the flush matters more. Why: it will not remain mixed, so diluting it is impossible; and crystals and corrosion outlast the following fill.
The same good news holds as with petrol. Anywhere around Caerphilly your car has stopped, an unrun motor means the AdBlue yet in the reservoir: the simplest part of any fuel system to empty.
How does AdBlue end up in a diesel tank in Old Treowen?
No one means to do it. The AdBlue filler on many vehicles sits right next to the diesel filler, at times under the same flap, and the two caps can look alike in poor light. Usually it is never the filling station: a driver buys a bottle heading home and pours it in at home.
A couple of familiar ways account for the majority of them. The top-up is rushed outside the local primary school, after the dash flashed with a warning as the children were taken off. Close to Bryn-Deri Terrace, someone tips a bottle in on the drive after work. One more version: darkness, the car park outside Newbridge Hotel, and someone using that flap for the first time.
The least familiar cars see it the most — hire cars, brand-new ones, fleet cars, and the other vehicle in a home with one of each fuels. Wherever in Caerphilly, Old Treowen included, the mistake does not change, and neither does the first step: leave it switched off.
AdBlue in your diesel tank around Old Treowen, and your engine started?
Then the AdBlue has left that tank. Via the filter, along the pipework, and — with any running time — into the injection pump and every injector: that's where it travels.
Rough running, smoke from the exhaust, dropping power, dashboard lights or cutting out: any might appear, maybe part way across Old Treowen or returning from Caetwmpyn Park. No restarting to check: stop when it is safe, then switch it off. More of that is pulled through with each start.
If you were on the M4, under 10 miles from Old Treowen, come off at the next exit and stop somewhere sensible instead of pressing on.
Distance counts: each mile pushes the AdBlue further in, and so heading towards Newport, under 10 miles away, gives a much bigger job than crossing Old Treowen to the car park by Newbridge War Memorial. Let us know roughly how far it had come.
There's more to flush once the engine has been started, and we do all of it where your car has ended up. Long-term damage is very rare if it is spotted quickly.
What does an AdBlue drain on a diesel involve in Old Treowen?
The vehicle remains put, whether that is a street beside Newbridge Tabernacle Baptist Church, a drive, a lay-by or a forecourt in Old Treowen, and our van comes to it. Three replies shape the work, so before anything else we ask what was put in, roughly what quantity, plus if the motor has run.
Next, emptying that tank right there takes out the polluted diesel along with the AdBlue in one go. A full flush matters much more after AdBlue than after petrol, because residue won't clear away by itself. Your filter is cleaned, or replaced where it needs to be; fresh diesel goes in; and your car is tested. The majority of these jobs are a half-hour visit once we arrive, if your engine has not run. Explosion-proof pumps make a busy forecourt safe to work on, and they run quiet enough not to disturb the street at night.
Lastly, the fuel system is bled with new diesel. Whether it's a parking bay by Newbridge or a driveway around Old Treowen, that is where our engineers start it and you head off. The check before our technicians head off is that it runs correctly on clean diesel. Our engineers do it all wherever the car has ended up, and it never needs to go to a garage. Your insurer is likely to want an engineer's report and the VAT invoice — each handed over afterwards.

Old Treowen: what AdBlue in a diesel tank costs to fix
Not one single figure could be fair, because each job differs. The cost shifts first with how long, if at all, your engine has been running, and next with the quantity of AdBlue that went in. After that it depends on where the car is and whether a van can reach it safely, which is easier on an open driveway than in a tight spot behind Saint Paul's.
What was put in, what quantity, plus whether it ran: every Old Treowen enquiry begins with exactly those, ahead of any figure, not after. Those replies shrink the range right down to a single number.
