AdBlue in a Diesel Tank in Aberaeron? Don't Start It
Motor off, ignition off: that's where you begin if AdBlue has gone into the diesel tank. Urea dissolved in water is what AdBlue is. The harm begins once it's pulled through the lines — it won't burn, and it won't combine with diesel. Caught before the motor has run, AdBlue in a diesel tank is normally a drain and a thorough flush, done where the car is in Aberaeron. Before anything, ring us on 0333 366 0103.
What to do right now, Aberaeron: AdBlue in your diesel tank
To do:
- Keys out — then nobody can switch anything on.
- Near moving traffic? So put the hazard lights on.
- Which fluid, and roughly how much volume? Save the bottle or the till receipt, and we can know.
- Ring us from where you are. A postcode starting SA46 0, or the name of the nearest street, brings the van to you without a search.
Do not:
- No starting your motor — not for a second, not to shift the vehicle.
- Switching the key to ignition by itself starts your pump running on plenty of diesels. Skip it.
- Adding extra diesel doesn't help: AdBlue settles out instead of blending.
- Keep the vehicle where it is instead of driving it anywhere, even a short distance along Bridge Street.
- Emptying the tank on your own by the road isn't one to try.
Ask the people behind the counter to help you move your car off the pumps if you are on a forecourt around Aberaeron, whether it's the Murco or somewhere else. At your own driveway, do not touch it at all.
AdBlue in a diesel tank, and what it does there
Made for the exhaust, AdBlue has no place in the motor. Kept in a separate tank, it is squirted into the exhaust to clean the gases. Nothing in an injection pump is designed for this liquid — and none of it was intended to travel that way.
Fuel mixes; AdBlue, once tipped in, won't. Its behaviour is nothing like diesel's. It's heavier than diesel, and so it sinks and collects at the bottom of your tank, which is where the pickup pulls fuel from. A car filled on a drive in Neuadd-Lwyd yesterday evening and left unstarted counts as the straightforward case. Nothing has sucked the AdBlue up so far — but when the engine turns, that's what goes first, directly from the bottom of that tank.
It causes two kinds of damage from there. It eats at certain metals used in fuel systems, working on whatever it reaches till it's cleared from the system. And once the water evaporates, the urea forms crystals that block filters and settle in narrow channels. If the AdBlue has reached the lines, leaving it overnight around Aberaeron makes things worse. In that tank alone, time costs nothing. Water lubricates nothing. The high-pressure pump and each injector need diesel running past them, so the water part damages them in its own right.
Why AdBlue in a diesel is often more serious than petrol
Put petrol in a diesel at the Gulf and you have an issue of thin fuel. No damage comes while it stays put, mixed into your diesel — only once your engine runs on it.
AdBlue in a diesel is another matter: not thin fuel, but no fuel at all. It does not burn, and so it cannot just be run through. Nor can it be watered down, because it splits back out — and the next tankful won't rinse away deposits or corrosion. So the flush matters for more here, and trying the engine "to see", in the heart of Aberaeron or out in Llwyncelyn, costs more than nearly any other slip.
As with petrol, there's good news. Never started? Then the AdBlue sits only in that tank, the simplest bit of the whole system to clear, anywhere your car has stopped around Ceredigion.
How AdBlue ends up in a diesel tank in Aberaeron
Many motors place the AdBlue filler alongside the diesel cap, now and then behind one flap, and in dim light the two may look the same. No one means it. It usually occurs at home, from a container bought en route home, not at the forecourt.
The ways it occurs are few and familiar. A warning light comes on during the school run, and the top-up takes place in a hurry outside the local primary school. A bottle is poured in at the end of the day on a drive just off Water Street. Another pattern: dim light, a pub car park by Castle Hotel, and someone opening that flap the first time.
Rented vehicles, new motors, fleet motors, or the second vehicle in a family with both fuels: the least known vehicles see it most. Wherever in Ceredigion, Aberaeron as well, the mistake doesn't change, and neither does the first response: leave it switched off.
Started your engine with AdBlue in your diesel tank around Aberaeron?
The AdBlue has left the tank, then. Through the fuel filter, through the pipework, and — given any running time — on to the high-pressure pump and every injector: that is where it has gone.
You may notice the motor running roughly, smoking, losing power, showing warning lights or cutting out, perhaps on the way back from Sgwar Alban or halfway across Aberaeron. No restarting to test: stop once it is safe, then turn everything off. More of it is pulled through with each start.
On the M4, under 50 miles from Aberaeron, the next junction is where to leave, and anywhere sensible is where to park — not carrying on.
Mileage matters: each mile pushes the AdBlue deeper in, and so heading towards Swansea, under 50 miles away, makes a much larger job than hopping across Aberaeron to the car park by Peniel Welsh Independent Chapel. Tell us about how far it had come.
Once the motor has been run, the flush covers more, and all of it is done where your car has come to a stop. Caught quickly, it very rarely leaves long-term damage.
Aberaeron: how AdBlue is cleared from a diesel
We come to your car, wherever it has stopped in Aberaeron: a side street close to Aberaeron Library, a drive, a lay-by or a forecourt. Before anything else our technicians ask what got in, roughly how much, and if your motor has run, since those answers decide this work.
Then that tank is cleared where your car stands, and so the tainted fuel and the AdBlue come out together. Your system is rinsed thoroughly, which counts more with AdBlue than with petrol, because what it leaves behind does not rinse out on its own. Fresh diesel goes in once the filter is cleaned — or swapped, when it needs to be — and after that your car is tested. If your motor has not run, the majority of jobs take about half an hour once our technicians arrive. Our pumping gear is explosion-proof, and so a busy filling station is no fault, and it is quiet enough for a residential street after dark.
Fresh diesel goes in to prime the system, and that is the final step. Firing it up comes next, and then you drive off from where your car is parked, outside the nearest station or on a drive in Aberaeron. We confirm it runs properly on new diesel before we leave. As the job is done in its entirety where your car is, a garage never comes into it. Insurers want a VAT invoice and an engineer report, and you get both at the end.

What does AdBlue in a diesel tank cost to sort out around Aberaeron?
Not one single price could be honest, since every job is different. Three things shift the price: whether the motor has run and for how long, how much AdBlue went in, and where your car is. That last one rests on whether a technician can get to it safely, and an open drive is simpler than a tight gap behind Holy Trinity.
Before any quote, not after, every enquiry from Aberaeron begins with the same three questions: the liquid, the quantity, plus whether the engine ran. Those answers turn a range into a straight price.
The price is given on the call, before anyone leaves; settling up happens on the day, by card or over the phone, and nothing upfront. Many insurance policies include misfuelling cover, and so it's worth checking yours whilst we're on the way.
