AdBlue in a Diesel Tank in Cefn-coed-y-cymmer? Don't Start It
With AdBlue in the diesel tank, your ignition remains off and so does your motor. Urea mixed in water is all AdBlue is. As it is water-based, it won't ignite and won't blend with diesel; damage just starts once your pump begins drawing it. Caught before your engine has been run, AdBlue in a diesel tank is generally a drain and a thorough flush, done where the car is around Cefn-coed-y-cymmer. Nothing comes before ringing 0333 366 0103.
What to do right now, Cefn-coed-y-cymmer: AdBlue in the diesel tank
Do:
- Keys out — then nobody can power anything on.
- If you're anywhere near moving traffic, put the hazard lights on.
- So you can give us which fluid it was and about what quantity, keep the till receipt or the empty bottle.
- Tell us a postcode starting CF48 2, or whatever street lies closest, and the van finds you directly — so ring from wherever you stand.
Don't do these:
- Shifting the vehicle even a few yards is no reason to fire up your engine.
- Don't switch your ignition on. On many diesels that alone runs the fuel pump.
- AdBlue does not mix in diesel — it separates out — so adding extra fuel won't weaken it.
- Even a short stretch down Bryntaf is too far to drive the car.
- Don't try to drain the vehicle yourself at the kerbside.
At a forecourt around Cefn-coed-y-cymmer, whether it is the Applegreen or another one, ask the attendants to help you roll your car clear of the petrol pump. Parked on your own driveway? Then it stays exactly where it is.
What AdBlue does in a diesel tank
The motor is not what AdBlue is made for; your exhaust is. Its own tank keeps it, and from there it's sprayed into your exhaust, and there it cleans the fumes. A fuel pump is not designed to take it, and AdBlue was never intended to go through one.
It does not combine. After it's tipped into the tank, AdBlue acts not at all like fuel. Heavier than diesel, it drops and pools below it — the same spot the pickup draws from. Once your pump runs, the AdBlue is top of the list to go through. Until then it sits beneath your diesel, and that is how a vehicle filled in Williamstown last night and never switched on stays the straightforward case, as long as no one touches the key.
Two kinds of harm follow from there. Crystals and corrosion. As the water dries, it strands urea that crystallises in filters and narrow channels; meanwhile, because it eats at some metals, each part it reaches keeps suffering for as long as it stays in there. Pipes carrying AdBlue mean harm overnight for a vehicle parked in Cefn-coed-y-cymmer. Only in the tank, it stays stable. Then there's the water: it brings no protection to the components that need it most — the high-pressure pump and each injector.
Why is AdBlue in a diesel frequently the bigger issue?
An issue of thin fuel is what you get from filling a diesel with petrol from the Esso. It mixes with your diesel, and while it is inside your tank it causes no harm; the harm comes from running your engine on it.
The issue with AdBlue in a diesel is a totally wrong substance. It does not burn, so it can't just be run through. Deposits and corrosion remain after the next tankful, and AdBlue separates back out of the diesel, so thinning it won't help. That is why the flush matters more, and turning your key "to see" does more harm with AdBlue than almost any other slip — in Gurnos or the centre of Cefn-coed-y-cymmer alike.
The good news is the same as with petrol. Clearing a tank is the simplest part on any fuel system, and without running, the AdBlue stays in it — anywhere around Merthyr Tydfil the vehicle sits.
How AdBlue ends up in a diesel tank around Cefn-coed-y-cymmer
No one means to do it. The AdBlue filler on plenty of motors waits right next to the diesel filler, occasionally under the same flap, and the two caps can look alike in poor light. It mostly happens at home, from a bottle grabbed on the journey home, not at the filling station.
A couple of familiar ways cover the majority of them. Halfway through the morning drop-off, the dashboard warns, and outside the local primary school the top-up is rushed. A bottle is poured in at the end of the day on a drive just off Old Chapel Road. Or someone new to that flap refills the car after dark, parked in the car park by The Lord Raglan.
The least known vehicles get it most — hire cars, new ones, company cars, and the spare vehicle of a home with one of each fuel types. Anywhere across Merthyr Tydfil, Cefn-coed-y-cymmer as well, the slip doesn't change, and neither does the first step: leave it off.
Already started the motor with AdBlue in the diesel tank around Cefn-coed-y-cymmer?
In that case, the AdBlue is no longer inside that tank. Through the filter, along the lines, and — given any running time — on to the injection pump and every injector: that is where it travels.
Expect rough running, smoke, lost power, warnings on your dash, or a stall — returning from Godre'r Coed Field, perhaps, or part way across Cefn-coed-y-cymmer. Stop when it is safe. Turn off. Keep the car off instead of testing it again. Each start pulls more of it through.
Cefn-coed-y-cymmer lies under 25 miles from the M4; if you were on it, exit by the next junction and pull up safely instead of driving on.
Hopping across Cefn-coed-y-cymmer to the car park by Hen Dy Cwrdd is one thing; driving towards Newport, under 25 miles away, is another, because each mile pushes the AdBlue further in. So mileage counts. Approximately how far had it come? Tell us.
Wherever the vehicle came to a stop is where all of it gets done, even with more to clean out once the engine has been running. When it's caught quickly, long-term damage is very rare.
What clearing AdBlue from a diesel involves around Cefn-coed-y-cymmer
Wherever it has stopped in Cefn-coed-y-cymmer — a filling station, a lay-by, a drive, a street beside cefn community centre — our van comes to your car. Before anything else our engineers ask what got in, roughly how much, and whether your engine has been run, since those replies decide the work.
Right there, the tank is then emptied, and both the polluted diesel and the urea leave as one. The fuel system is purged thoroughly, which matters more with AdBlue than with petrol, because what it leaves behind does not rinse out on its own. Next, the filter: cleaned, or changed if it must be. Then clean diesel, and then a check of your vehicle. About half an hour once we arrive is usual for most jobs when your motor has not run. Low-noise enough to use outside a house at night, and fine on a working forecourt, the pumps are explosion-proof.
Bleeding the fuel system with fresh diesel comes at the end. After that our technicians start the car and you head off, whether from a parking space by Merthyr Tydfil or a drive in Cefn-coed-y-cymmer. Before we go, our engineers make sure it is running properly with new diesel in. Our engineers do it all wherever the car has ended up, and it never has to go to a garage. The insurer will want an engineer's report and the VAT invoice — both yours once this job is done.
