AdBlue in the Diesel Tank in Cefncaeau: What Now?
What to do about AdBlue in a diesel tank depends on one thing more than any other: if your motor has been run since it got in. Not run so far? Then keep the car like that, whether the car is — Cefncaeau or Pemberton. Switch nothing on, phone 0333 366 0103, then count on a thorough flush plus a drain, carried out just where the car stands in Cefncaeau. Where your engine has run, stop somewhere safe straight away, then turn the car off. Step one remains unchanged, even if the work is bigger.
Below: the cases our technicians see, anywhere in Carmarthenshire. Pick the one that fits.
At the petrol pump in Cefncaeau: AdBlue in a diesel
Only now, bottle still in hand, it dawns on you that the cap you took off was the wrong one, there at the petrol pump. Perhaps you are at the Texaco, maybe at the Morrisons, possibly somewhere else around Cefncaeau.
The point: of all places to find out, this is the best. Still in that tank, and nothing pulled onwards: that is where the AdBlue is.
What to do: do not get back in and fire it up to clear the petrol pump. Have the staff to lend a hand rolling it into a space, hold on to the bottle, then ring us right 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 Cefncaeau with AdBlue in the diesel tank
On the dash, a reminder had shown all week. Only by the recycling, the empty bottle in your hand, did you look back at the cap you had used on the drive. Just off Llwynhendy Road is no different from anywhere.
What it means: if you haven't driven since, this is almost as good as the forecourt. Being unable to blend, AdBlue settles low inside your tank and waits. A night parked alters nothing.
Put the keys indoors tonight — otherwise someone might take it off at breakfast — and phone us. Our engineers drain the car on your drive, whether that is in Cefncaeau or out in Cwmcarnhywel. Late-night clears beside a house are no problem: the pumps are quiet.
AdBlue in a diesel and already driving around Cefncaeau?
Filled up, drove away, and soon the motor was turning unevenly, blowing smoke, losing power, or flashing up the dash. Heol Hen, say, or the route towards Swansea — a run of under 10 miles.
Meaning? The fuel pump has sucked the AdBlue in. The high-pressure pump and each injector see it as well on a longer run, after the filter and pipework have it. More driving, more restarts: deeper it travels.
Next: pick a safe spot, pull in, then switch the motor off. On the M4, under 5 miles from Cefncaeau, that means the next junction, not the services further on. No test starts: clearing isn't something AdBlue will do. Call us and say how far you went.
AdBlue in the wrong tank: hire, lease and company motors
You have only had the vehicle a week. Your own car either does without AdBlue or keeps it elsewhere, so no one told you the AdBlue cap sits just next to your diesel. Anywhere you are around Carmarthenshire, every motorist could be caught.
Put simply: an extra stage on top of the situations above, which depend on whether it's run. Many hire and company contracts want the owner to approve work on the car.
Sorting it before we turn up is quicker, so ring the hire company or your fleet manager, then us. If you are stuck in the car park outside Bynea, or by Tabernacl Baptist Church, whilst you wait for an answer, leave the car off.
Cefncaeau: unsure if it was AdBlue in your diesel tank?
Now and then, "I think so" is the most you can honestly say. A faint ammonia whiff hangs around your filler, the bottle seems too light, and the cap you took off is hard to recall. The gates of the local primary school in a rush, say, or someone's driveway over in Halfway.
Meaning? Spills outside the filler never touch your engine at all. A diesel tank with AdBlue inside is a different story. If there is AdBlue in that tank, turning on the vehicle would draw it in, and it would not tell you which either.
Next: assume it got in, then keep your engine off. Describe what you noticed on the phone. A clean tank looked at counts as a happier result than an already-run one emptied.
The common ground in every Cefncaeau AdBlue drain
Each situation has the same start to the work. Anywhere the car stands — Joiners Arms's car park, a road beside Llywnhendy Library, a driveway, a filling station — our van arrives and asks about the fluid, the quantity, plus whether your engine has been run. The price comes on the call, ahead of anyone setting off, and those answers shape the work.
AdBlue forms crystals and is corrosive to certain metals in fuel systems, so it does not rinse out on its own; that's why a full flush, after the drain, matters far more here than with petrol. Fresh diesel goes in once your filter has been cleaned or replaced, and the car is then tested. Not started? In that case roughly half an hour on site covers most jobs.
Starting it comes last. Our technicians make sure it runs correctly on fresh diesel before leaving. Our engineers do the entire job where your car is, and permanent damage is very uncommon if it has been spotted soon. For your insurer: an engineer's report and the VAT invoice. For you: payment on the day, no money in advance. Plenty of insurance policies include misfuelling, and so look at yours while the van travels.
