AdBlue in the Diesel Tank in Cadle: What Now?
Everything hinges on a single detail: if your engine has been run since the AdBlue went in — far more than anything else. Over in Raven Hill or here in Cadle, an unstarted engine must remain unrun. Phone 0333 366 0103 with your key and engine both off. Across Cadle, that is typically emptied and cleaned where it stands. Already run? Stop once safe, then turn everything off. The job is bigger, but the first step is the same.
Compare your case to a situation from the list below, wherever around Swansea you are.
At the petrol pump in Cadle: AdBlue in a diesel
Imagine it: standing by the petrol pump, holding the nozzle, you spot the cap you opened wasn't the correct one. Maybe you're at the Tesco, maybe at the Applegreen, possibly somewhere else around Cadle.
Meaning? Spotting it here is the best it gets. The AdBlue is in your tank and nowhere else. Nothing has drawn it in.
What to do: don't get back in and start the vehicle to clear the pump. Get the staff to lend a hand rolling it to a bay, hold on to the receipt, then ring us from there. If it can't be shifted, it can be emptied at the pump: the equipment is explosion-proof and safe on a working forecourt.
At home around Cadle with AdBlue in your diesel tank
For days the dashboard had been warning you. Picked up a container, tipped it in outside the house, binned the empty — and at that point looked at the cap a second time, too late. Just off Pontarddulais Road is not different from any other place.
Meaning? Provided your car hasn't been driven since, it is close to the forecourt case. AdBlue does not mix with diesel; it sinks to the bottom of your tank and waits there. Overnight doesn't change that.
Next: prevent an early-morning drive by putting the keys indoors, then ring us. Your drive is where it gets drained, be it in Cadle or Port Mead. The pumps are quiet enough to use outside a house after dark.
AdBlue in a diesel and already driving in Cadle?
Topped up, pulled away, and soon your engine was turning unevenly, blowing smoke, losing power, or lighting up the dash. Maybe driving for Swansea, under 5 miles away, or just down Ffordd Cynore.
The point: your system has pulled AdBlue in by now. The high-pressure pump and every injector see it as well on a bigger trip, after your filter and lines have it. Every restart, like each mile, pushes it deeper.
Pull in safely — that is the first job — then switch it off. On the M4, under 3 miles from Cadle, that means the next junction, not the services further on. Restarting it to test achieves nothing — AdBlue never clears itself. Phone, saying how far your car was driven.
AdBlue in the wrong tank: hire, lease and company motors
Seven days back, the car was new to you. Unbeknown to you, the AdBlue and diesel fillers are next to each other here — not like your own vehicle, which has none or stores it elsewhere. It can happen to anyone, anywhere in Swansea.
In short: one extra stage on top of the cases above, which depend on whether it has run. Any work on the car often needs the owner's go-ahead under rental or company agreements.
What to do: call the hire firm or your fleet manager first, then us. That's quicker settled before we get there than after. Keep the car switched off while the answer arrives, even if you are parked at Gowerton or close to St. Illtyd's.
Cadle: unsure whether it was AdBlue in the diesel tank?
"I think so" is sometimes as honest as it gets. A slight ammonia smell lingers near your filler, the bottle feels too light, and the cap you took off is a blur. A rushed stop by the gates of the local primary school, or a visit to a friend in Mynydd-bach-y-glo: either fits.
What it means: a little spilled around the filler does no damage to your engine. The diesel tank with AdBlue inside is a different story. Starting your car cannot tell you which, and if there is AdBlue in that tank it will suck it in.
What to do: treat it as if it was put in. Do not start the vehicle. Describe what you saw on your phone. A clean tank looked at counts as a happier outcome than a run one emptied.
What every AdBlue drain in Cadle has in common
Every situation has the same opening to the job. Filling station, driveway, Mary Dillwyn's car park or a road beside Caersalem — our van comes to the car, and three answers follow: which fluid, which amount, and whether it has run. Those answers determine the work, and you hear the quote by phone, before anybody heads out.
Then the tank is cleared and the system rinsed thoroughly, which matters more with AdBlue than with petrol: AdBlue crystallises and is corrosive to some of the metals in a fuel system, and so it doesn't rinse out on its own. The filter is cleaned, or replaced where it needs to be; clean diesel goes in; and your car is tested. Most unrun vehicles are a half-hour visit after the moment our technicians arrive.
Our technicians start the car last. Our test that it runs properly on fresh diesel comes before our engineers leave. Long-term damage is very rare if it is spotted soon, and the entire job is done where the car is. You pay on the day, with nothing upfront, and get a VAT invoice and an engineer report for your insurer. Check your insurance before we're en route: cover for misfuelling is included in many policies.
