AdBlue in the Diesel Tank in Cnap-Llwyd: What Now?
Has your motor run since the AdBlue went in? That single question settles almost everything about what comes next. Wherever your vehicle stands — Lisbon, Cnap-Llwyd — never run an engine that has not run yet. Leave the engine and the ignition off then call 0333 366 0103; it is usually a drain and a thorough flush, done where the vehicle is in Cnap-Llwyd. Already started? Pull over when safe, then turn everything off. A larger job, yes, yet the same first step.
Match what happened to one of the ones below, anywhere across Swansea you are.
AdBlue in a diesel on a Cnap-Llwyd forecourt
You're at the petrol pump, the nozzle or the bottle still in your hand, and you have just noticed the cap you opened was the wrong one. Possibly you're at the Texaco, possibly at the Morrisons, perhaps somewhere else around Cnap-Llwyd.
Meaning? Finding out on the forecourt is the best it can be. Still in your tank, and nothing drawn onwards: that's where the AdBlue sits.
Next: avoid the urge to fire it up only to free up the petrol pump. Ring us from the forecourt once the car is in a space — the staff will lend a hand to roll it — then keep the bottle. The equipment is explosion-proof and safe on a live forecourt, so a car that cannot be pushed clear gets drained where it is at the petrol pump.
At home in Cnap-Llwyd with AdBlue in your diesel tank
For days the dash had been warning you. You bought a bottle, poured it in on the drive, and only when you put the empty bottle in the recycling did you look a second time at the cap. Driveways close to Trewyddfa Road see it as much as any other street.
What it means: if you have not driven since, this is almost as good as the forecourt. On the floor of the tank is exactly where AdBlue stays, since it won't blend with diesel — and a night going by changes no difference.
Next: stop any early-morning drive by putting the keys indoors, then ring us. In Plas-Marl or right here in Cnap-Llwyd, the draining happens on your driveway. The pumping kit runs quiet enough that it won't wake the neighbours at night.
Drove off with AdBlue in a diesel around Cnap-Llwyd?
You filled up, set off, and a mile or two later the engine began to run unevenly, smoke, lose power or light up the dashboard. Somewhere along Britannia Road or on the road towards Swansea — under 3 miles away.
The upshot: your system has drawn AdBlue in already. Distance decides how deep it goes: filter and pipework first, then the high-pressure pump and every injector. More driving, more starts: further it goes.
Next: find a safe place, pull in, then turn your motor off. Service stations further along can wait: on the M4, under 3 miles out of Cnap-Llwyd, use the first junction. No test restarts: clearing is not something AdBlue does. Phone us and say how far you travelled.
Hire, lease or company car with AdBlue in the wrong tank
You have had the vehicle barely a week. Your own motor either has no AdBlue or puts it somewhere different, so nothing warned you the AdBlue cap was right next to your diesel. It can happen to anyone, anywhere around Swansea.
The point: exactly as above, split by whether it ran, only with one added stage. Plenty of rental and fleet contracts require the owner's approval before repairs.
Settling it before the van arrives is faster, so phone the rental company or your fleet manager, then us. Waiting for a reply at the car park at Swansea, or near Morris Castle? Leave the car off throughout.
Cnap-Llwyd: unsure if it was AdBlue in your diesel tank?
Now and then, "I think so" is the most you can honestly say. The bottle is lighter than it should be, there's a faint smell of ammonia about the filler, and you can't remember which cap you took off. A rushed top-up by the gates of the local primary school, or a call to a friend in Landore: both fits.
Put simply: spillage near the filler leaves the engine unharmed. Once it's inside your diesel tank, though, it does. Any AdBlue in your tank will be drawn in by firing up the car, and the start wouldn't settle which it is in any case.
Next: assume it got in, then leave your engine off. Ring us and describe what you saw; we'd rather check a tank that turns out free of AdBlue than drain one that has already been run.
Every AdBlue drain in Cnap-Llwyd shares these steps
The job begins identically, whatever your situation. Wherever your vehicle stands — Dillwyn Arms's car park, a road beside Swansea Indoor Bowls Stadium, a drive, a filling station — the van arrives and we ask about the liquid, the quantity, and if your engine has been run. Over the phone, before anything else, you are told the quote, and those replies shape the work too.
Then that tank is drained and the system flushed 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 fuel filter is flushed, or replaced where it needs to be; clean diesel goes in; and the vehicle is tested. If your engine hasn't run, the majority of jobs take about half an hour once we are there.
Starting the car comes at the end. With clean diesel in, it runs while we confirm it is running properly, and then we head off. The whole job is done where the vehicle is, and if it is noticed quickly, permanent damage is very uncommon. Paying comes that day, never in advance. For your insurer, there is a VAT invoice and a report from the engineer. Plenty of insurance policies cover misfuelling, so look at yours while the van travels.
