AdBlue in the Diesel Tank in Pengam? Keep It Switched Off
AdBlue in your diesel tank? Then leave your engine off — and the ignition as well. In plain terms, AdBlue is just urea in water. It does not burn, it does not mix with diesel, and the damage it does begins when the fuel system pulls it in. Caught before the motor has been run, AdBlue in a diesel tank is usually a drain and a thorough flush, done where your car is around Pengam. First, phone us on 0333 366 0103.
AdBlue in your diesel tank in Pengam: the first few minutes
Do:
- Keys out — that way nobody can power anything on.
- Close to moving traffic? So put the hazards on.
- Hold on to your receipt or the empty bottle, so you can tell us what got in and about how much.
- Tell us a postcode starting CF24 2, or whatever street lies closest, and the van reaches you straight — so call from wherever you stand.
Never do these:
- Moving the car even a few yards is no reason to fire up your motor.
- Do not switch the ignition on. On many diesels that alone runs the fuel pump.
- Do not top up with diesel to thin it. AdBlue does not dilute in diesel; it separates out.
- Even a short way up Ffordd Pengam is too far to drive the car.
- Don't try to drain the car yourself by the kerbside.
Moving your car off the island is a job for attendants to help with, wherever Pengam forecourt you are on, the Shell included. If you are on your own drive, leave the car precisely where it is.
What does AdBlue do in a diesel tank?
Made for your exhaust, AdBlue has no business in your motor. Kept in a separate tank, it is squirted into the exhaust to treat the gases. Nothing in it is meant to pass through a fuel pump, and nothing in a fuel pump is made to handle it.
Fuel blends; AdBlue, once tipped in, will not. The behaviour is nothing like diesel's. It sinks, because it's denser than diesel, and pools low where the intake draws its fuel from. When the pump runs, the AdBlue is first to be pulled through. Until then it sits underneath the diesel, which is how a car filled in Pwll-Mawr last night and not switched on stays the simple one, as long as no one touches the key.
Once it is pulled in, the damage comes in two forms. What is left when the water goes is urea, which turns into crystals: they settle in narrow channels and block filters. Worse, it eats at some metals in the fuel system, and keeps going till it is cleared out. A car left standing in Pengam with AdBlue already in its lines is worse by the morning; one with AdBlue only in its tank isn't. Water protects nothing. The injection pump and every injector need diesel running through them, and so the water content harms them in its own right.
Why AdBlue in a diesel is regularly more serious than petrol
Put petrol in a diesel at the Tesco and you have a fault of thin fuel. Mixed into your diesel and left still, it's no threat at that stage; using the engine does the harm.
The trouble with AdBlue in a diesel is a totally unsuitable substance. Because it doesn't burn, running it through is not an option. Whether your vehicle is in Splott or the centre of Pengam, turning it over "to see" costs more with AdBlue than almost any other error, and the flush matters for more. The reasons: it won't remain mixed, so watering it down is impossible; and crystals and corrosion survive the following tankful.
With AdBlue, the good news is no distinct from petrol. If your motor hasn't run, the AdBlue is still inside that tank, and the tank is the quickest part of a fuel system to clear, wherever across Cardiff your car is sitting.
How does AdBlue end up in a diesel tank in Pengam?
Nobody means to do it. The AdBlue filler on many vehicles waits right next to the diesel filler, sometimes under the same flap, and the two caps can look alike in poor light. Mostly it's not the forecourt: a driver buys a container heading home and tips it in outside the house.
Mostly, it takes place in one of a few familiar ways. A warning light comes on during the school run, and the top-up happens in a hurry outside the local primary school. In the evening, a container goes in on a drive near Southern Way. Or your car is topped up in the car park at The Royal Oak, in poor light, by somebody who has never opened that flap before.
Hired motors, new motors, fleet motors, or the second car in a home with both fuels: the least known cars see it most. Anywhere around Cardiff, Pengam as well, the slip doesn't change, and nor does the first step: leave it switched off.
Already started your engine with AdBlue in your diesel tank in Pengam?
Then the tank is no longer where the AdBlue is. It has been sucked through the fuel filter and the fuel lines, and if your engine ran for any time, it has reached the high-pressure pump and the fuel injectors.
Maybe coming back from Beaufort Square Park, or part way across Pengam, your motor may run rough, smoke, lose power, flash your dash or stall. No starting it again to check: stop when safe, then switch it off. Each start pulls more of it through.
Pengam sits under 3 miles from the A48(M); if you were on it, leave at the first junction and pull up somewhere safe rather than driving on.
Mileage matters: each mile pushes the AdBlue further in, and so heading for Cardiff, under 3 miles away, makes a far bigger job than hopping across Pengam to the car park by Tremorfa Adult Training Centre. Roughly how far had it come? Tell us.
Once the engine has run, the flush includes more, and all of it is done where the car has ended up. Very seldom does it leave lasting damage when it is noticed soon.
What emptying AdBlue from a diesel involves in Pengam
We come to the car, wherever it has stopped in Pengam: a side street near Belmont Baptist Church, a drive, a lay-by or a forecourt. What was put in, roughly how much, and if the engine has turned over: we check first, since those shape the work.
The polluted diesel and the urea come out together when the tank is drained, on the spot. A careful flush matters far more with AdBlue than after petrol, because what remains will not clear out by itself. Testing your vehicle comes last, once clean diesel goes in and the fuel filter gets cleaned or, if necessary, swapped. If the engine has not run, the majority of jobs take about half an hour once our engineers are there. Our equipment is explosion-proof, and so a busy filling station is no fault, and it's quiet enough for a residential street late at night.
Bleeding the fuel system with clean diesel comes at the end. At that point our engineers fire it up and you drive off, whether from a parking space by Cardiff Queen Street or a driveway in Pengam. Before leaving, our technicians confirm it's running correctly with fresh diesel in. The entire job is done where the vehicle is, so it never has to go to a garage. Your insurer is likely to want an engineer's report and the VAT invoice — both yours once the job is done.

Pengam and Cardiff: AdBlue drains across the area

Wherever your vehicle sits — your drive at home, a residential street, a parking area, a forecourt — our engineers empty it there, with no need to take it to us; that suits Pengam, a residential suburb, well.
AdBlue in a diesel tank around Pengam: the cost of fixing it
Each job differs, and so not one fixed price is fair. Three things move the cost: whether the engine has been running and for how long, how much AdBlue went in, and where the vehicle is. That last one comes down to whether our van can reach it safely, and an open drive is simpler than a tight space behind Boulders Climbing Centre.
Which fluid went in, how much, and whether the engine ran: every Pengam call begins by asking exactly those, ahead of any figure, not after. Given them, the range shrinks to a single fixed number.
Our quote is quoted on the call, before anyone sets off; settling up comes on the day, by card or by phone, and nothing upfront. As our engineer is on the way, check your insurance: plenty include misfuelling.
In Pengam and still alongside your car?
Not touching your car is, right now, the most useful thing open to you. Ignition off, engine off, keys out. Call 0333 366 0103: AdBlue, roughly how much, and whether it ran is everything our technicians ask. Petrol in Diesel handles the remainder across Cardiff, Pengam too.
