What Now? AdBlue in the Diesel Tank in Cwmrhydyceirw
All of that turns on one detail: whether your engine has started since the AdBlue was added — more than anything else. Out in Cwm-felin-fach or here around Cwmrhydyceirw, an unstarted engine must stay that way. Normally that means emptying and thoroughly purging it right there around Cwmrhydyceirw — and so keep the key and engine off and call 0333 366 0103. Already started? Stop when you safely can, then turn everything off. Stage one stays unchanged, even if the work is bigger.

At the petrol pump around Cwmrhydyceirw: AdBlue in a diesel
The cap you unscrewed was the wrong one — and you just spot it while you're stood at the pump, bottle or the nozzle in hand. Anywhere around Cwmrhydyceirw, then — Asda, BP, or anywhere else nearby.
What it means: this is the best place to find out. Just the tank holds AdBlue; not one component beyond it has taken it in.
What to do: do not get back in and fire it up to clear the pump. Phone us from the forecourt after your vehicle is in a bay — the staff will help push it — and keep the bottle. Our equipment is explosion-proof and safe on a live forecourt, so a vehicle that cannot be pushed clear gets cleared where it is at the petrol pump.
Cwmrhydyceirw, at home: AdBlue in the diesel tank
For days the dashboard had been nagging you. Bought a bottle, poured it in at home, recycled the empty — and only then checked the cap again, after the fact. Homes just off Llanllienwen Road are caught out as often as everywhere else.
The upshot: zero driving since makes this nearly equal to finding it at the pump. AdBlue does not mix with diesel; it sinks to the bottom of that tank and waits there. Overnight doesn't change that.
Keep the keys indoors tonight — otherwise someone may drive it away at breakfast — then phone us. Your drive is where it is emptied, be it around Cwmrhydyceirw or Pen-rhiw-forgan. The equipment works quietly enough not to disturb the neighbours at night.
On the road in Cwmrhydyceirw with AdBlue in a diesel
You filled up, set off, and a mile or two later the motor began to run roughly, smoke, lose power or light up the dashboard. It might have been heading for Swansea, under 5 miles away, or simply down Heol Y Deri.
What it means: the system has pulled the AdBlue in. Mileage sets how far it gets: filter and pipework first, then the injection pump and each injector. Each mile and each restart takes it further.
Stop somewhere safe — that's the next job — then turn everything off. Cwmrhydyceirw lies under a mile from the M4; on it, come off at the first junction instead of pressing on for the services. Starting it again to check gets nothing — AdBlue doesn't clear itself. Tell us hear the distance driven when you ring.
AdBlue in the wrong tank of a hire, lease or company car
A week ago, it was unknown to you. Unknown to you, the AdBlue and diesel inlets are side by side here — unlike your own vehicle, which has none or keeps it in another spot. Any driver, wherever around Swansea, might do it.
What it means: the same as the scenarios above, depending on whether it has run, with one more stage. Many hire and company contracts require the owner's sign-off before repairs.
Do this: hire firm or your fleet manager first, us second, since sorting it early saves time. If you're stuck in the car park outside Llansamlet, or by Morriston Leisure Centre, while you wait for an answer, leave the vehicle off.
Cwmrhydyceirw: unsure if it was AdBlue in your diesel tank?
Occasionally the fair answer is "I think so". The bottle is lighter than it should be, there's a faint smell of ammonia around your 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 Tircanol: both fits.
Put simply: spillage near your filler leaves the engine unharmed. AdBlue inside the diesel tank does. Firing up the vehicle won't tell you which, and if there is AdBlue in the tank it would suck it in.
What to do: treat it as if it went in. Do not crank it. Ring and give the details: we'd sooner find a tank free of AdBlue than empty one after the engine has run.
Cwmrhydyceirw: what each AdBlue drain has in common
Whichever situation you are in, this job starts the same way. Our engineers come to your car, whether it is on a forecourt, a driveway, the car park at Deer's Leap or a side street near Morriston Library, and ask three things: what was put in, about how much, and if the motor has been run. Your price is given over the phone, ahead of anyone setting off, and the answers shape the job.
AdBlue forms crystals and is corrosive to certain metals used in fuel systems, so it does not rinse out unaided; that is why the flush, after this drain, matters far more with AdBlue than with petrol. The fuel filter is flushed, or replaced where it needs to be; fresh diesel goes in; and your car is tested. Most unrun cars are a half-hour job after the moment our technicians turn up.
Firing it up comes at the end. Before our technicians go, it is tested to be sure it runs correctly on fresh diesel. The whole job is done where the vehicle is, and if it is spotted soon, lasting damage is very uncommon. You pay on the day, with nothing upfront, and get a VAT invoice and an engineer report for your insurer. It is worth knowing: many insurers offer misfuelling cover, so a quick look at your documents while we travel is worthwhile.
