AdBlue in the Diesel Tank in Llan Ffestiniog, and What to Do Next
Everything hinges on a single fact: whether the engine has started since the AdBlue went in — far more than anything else. If it hasn't, keep it that way, whether the vehicle is in Llan Ffestiniog itself or out in Congl-y-wal. Leave the motor and your ignition off then call 0333 366 0103; it's usually a drain and a thorough flush, done where the vehicle is in Llan Ffestiniog. Where the engine has run, stop safely straight away, then switch the vehicle off. It is a larger job, yet step one doesn't change.

At the pump around Llan Ffestiniog: AdBlue in a diesel
Imagine it: stood by the petrol pump, gripping the bottle, you realise the filler you opened wasn't the right one. It could be the Essar, or the another forecourt nearby, or another forecourt around Llan Ffestiniog.
Put simply: no better place exists to spot it. Still in the tank, with no fuel drawn onwards: that is where the AdBlue sits.
Clearing the petrol pump is no excuse to run it — and so do not get back in. Three things: a push into a space with the staff assisting, the bottle saved, and a call to us from where you stand. If it can't be shifted, it can be drained at the pump: the equipment is explosion-proof and fine on a working forecourt.
AdBlue in the diesel tank at home in Llan Ffestiniog
Several days had gone by with the dash light on. Only by the recycling, the empty bottle in hand, did you look back at the cap you'd used on the driveway. Right off Ffordd Blaenau / Blaenau Road is not less likely from any other place.
In short: if your car has not moved since, it's nearly equal to spotting it at the forecourt. AdBlue doesn't mix with diesel; it sinks to the bottom of that tank and waits there. Overnight does not change that.
Next: prevent an early-morning drive by putting your keys indoors, then ring us. Your drive is where it is emptied, whether around Llan Ffestiniog or Rhyd-y-sarn. Night-time clears beside a house are fine: the pumps are quiet.
On the road in Llan Ffestiniog with AdBlue in a diesel
You filled up, set off, and a mile or two later your motor began to run unevenly, smoke, lose power or light up the dashboard. Pen-y-bryn, say, or the way to Bangor — a trip of under 25 miles.
In short: the AdBlue has been pulled through the system. The high-pressure pump and every injector get it as well on a bigger run, after the fuel filter and lines have it. Each mile and each restart takes it further.
Do this: stop somewhere sensible, then switch your motor off. On the M53, under 50 miles from Llan Ffestiniog, that means the next junction, not the services further on. Starting it again to check gets nothing — AdBlue doesn't clear on its own. Call, and say what distance the car was driven.
A hire or company car with AdBlue in the wrong tank?
You've had this car hardly a week. Unknown to you, the two inlets sit side by side here — unlike your own vehicle, which has no AdBlue or stores it elsewhere. Anywhere you are across Gwynedd, every motorist can slip up.
In short: one extra step on top of the cases above, which turn on whether it's run. Many hire and fleet contracts need the owner's sign-off before work.
Your move: hire firm or your fleet manager first, us second, because sorting it early cuts time. Stuck by Neuadd Ffestiniog or outside Blaenau Ffestiniog until the firm replies, your car stays switched off throughout.
Not sure it was AdBlue in the diesel tank, Llan Ffestiniog?
At times, "I think so" is all you can honestly say. Lighter, that bottle; a hint of ammonia near the filler; no clear recollection of the cap. Sound familiar? It might have been on a friend's driveway in Manod, or rushing by the local primary school at the school run.
The point: your motor is not harmed by a little AdBlue splashed around the filler. Once it is inside the diesel tank, though, that changes. You cannot tell which by turning the key, and doing so would suck in any AdBlue that is in that tank.
Next: act as though it got in, then keep the motor off. Inspecting a tank that proves clean is better than emptying one once it's been run — so phone then describe to us what you saw.
The common ground in every Llan Ffestiniog AdBlue drain
The work begins identically, whichever your case. Our engineers come to your car, whether it is at a forecourt, a driveway, the car park at Pengwern Arms or a side street near Church Hall, and ask three things: what got in, roughly how much, and if the engine has run. Replies set the work; the quote follows on the call while no one has left yet.
A thorough flush follows this drain. With petrol it's routine; with AdBlue it is essential, since crystals build up and certain metals are attacked, and none of it washes away unaided. The filter is cleaned, or replaced where it needs to be; clean diesel goes in; and your car is tested. If the engine hasn't run, the majority of jobs take about half an hour once we're there.
The last step is firing it up. Our test that it runs smoothly on fresh diesel comes before we head off. Permanent damage is very rare when it's noticed early, and the entire job is done where the vehicle is. You pay on the day, with nothing upfront, and get a VAT invoice and an engineer report for your insurer. Check your insurance while we arrive: misfuelling cover is included in many policies.
