Gwernymynydd: AdBlue in the Diesel Tank? Find Your Situation
One fact counts above all once AdBlue is in a diesel tank, and it is if the motor has run afterwards. Wherever your vehicle is — Maeshafn, Gwernymynydd — don't run a motor that hasn't been started yet. Normally that is draining and properly cleaning it right there in Gwernymynydd — so keep the key and engine off then ring 0333 366 0103. Stop the moment you safely can then switch off, if it has already run. The job is bigger, yet the first stage is the same.
Match what happened to a situation from the ones below, anywhere across Flintshire you are.
AdBlue in a diesel on a Gwernymynydd forecourt
Just at this point, bottle yet in your hand, it dawns on you that the cap you took off was the wrong one, there at the petrol pump. Maybe you are at the Texaco, perhaps at the Tesco, possibly somewhere else in Gwernymynydd.
In short: no better spot exists to discover it. Still inside that tank, with no fuel pulled through: that's where the AdBlue sits.
What to do: don't get back in and start the vehicle to clear the pump. Phone us from the forecourt once the car is in a bay — the attendants will lend a hand to roll it — then keep the bottle. Our equipment is explosion-proof and fine on a busy forecourt, so a car that cannot be pushed clear is drained where it is at the pump.
AdBlue in the diesel tank at home in Gwernymynydd
Days had gone by with the dash light on. Picked up a bottle, tipped it in at home, recycled the empty — and only then looked at the cap again, after the fact. It happens on drives just off Glyndwr Road as commonly as anywhere.
The point: no miles since makes it nearly as good to spotting it at the pump. On the bottom of your tank sits exactly where AdBlue stays, because it will not blend with diesel — and a night passing makes nothing of the difference.
Next: keys indoors, and so no one takes the car anywhere first thing. Then, phone. Your driveway is where it is emptied, be it around Gwernymynydd or Cadole. Even at night, the pumps stay quiet enough for a residential street.
Gwernymynydd: drove off with AdBlue in a diesel?
Topped up, drove away, and before long your engine was turning unevenly, blowing smoke, down on power, or lighting up the dash. It might have been driving for Wrexham, under 15 miles away, or just along Lime Kiln Court.
Meaning? The fuel pump has taken the AdBlue in. Mileage sets how deep it gets: filter and pipework to begin with, then the high-pressure pump and every injector. It travels further with each mile driven and each restart.
What to do: pull over where it is safe to do so then switch off. Gwernymynydd sits under 15 miles from the M56; on it, pull off at the first junction instead of pressing on to the services. No test starts: clearing isn't something AdBlue does. About what distance had it gone? Tell us when you phone.
A hire or company car with AdBlue in the wrong tank?
A week back, it was unknown to you. The AdBlue filler sits right beside the diesel one, which you didn't know, since your own vehicle either has no AdBlue or keeps it somewhere else. Anywhere you happen to be in Flintshire, any motorist could slip up.
What it means: the same as the scenarios above, depending on whether it has run, with one more stage. Many rental and fleet contracts need the owner's approval before repairs.
Sorting it before we arrives is faster, and so ring the hire company or your fleet manager, then us. If you are stranded in the car park outside Buckley, or by Gwernymynydd Village Hall, whilst you wait for an answer, leave the car off.
Gwernymynydd: unsure if it was AdBlue in your diesel tank?
At times the fair answer is "I think so". Lighter, the bottle; a hint of ammonia near the filler; no clear memory of which cap. Look familiar? Maybe it happened in a hurry at the school gates at the local primary school, or on a friend's drive in Pant-y-buarth.
In short: a spill round your filler does your motor unharmed. If it's inside your diesel tank, though, it does. You can't tell which by turning the key, and doing so will suck in any AdBlue that is in your tank.
What to do: treat it as if it got in. Don't start the car. Describe what you noticed on your phone. A clean tank checked counts as a happier result than an already-run one emptied.
Gwernymynydd: what every AdBlue drain has in common
Whichever situation you are in, this job starts the same way. Anywhere your car is — The Swan Inn's car park, a street beside Capel Soar, a driveway, a forecourt — the van gets there and asks for the liquid, the quantity, plus if your engine has been run. The price is given over the phone, ahead of anyone setting off, and those replies set the work.
Then the tank is cleared and the fuel 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 does not rinse out on its own. The filter is cleaned, or replaced where it needs to be; clean diesel goes in; and the car is tested. Never started? In that case roughly half an hour once we are there is most jobs.
Firing it up comes at the end. Our technicians make sure it runs correctly on fresh diesel before we leave. When it is caught quickly, the car very rarely has long-term damage, and the entire job happens where it is. You pay on the day, with nothing upfront, and get a VAT invoice and an engineer report for your insurer. Many insurance policies include misfuelling cover, so it is worth checking yours while we are on the way.
