What Now? AdBlue in the Diesel Tank in Llangwm
What to do about AdBlue in a diesel tank comes down to one thing more than any other: whether the engine has been run since it got in. If it has not, keep it that way, whether the vehicle is around Llangwm itself or out in Port Lion. Normally that is emptying and properly rinsing it right there in Llangwm — and so leave your key and motor off and call 0333 366 0103. Already run? Pull over when safe, then switch it off. A bigger job, yes, yet the same first step.

At the petrol pump around Llangwm: AdBlue in a diesel
Picture it: stood by the pump, gripping the nozzle, you realise the filler you took off was not the correct one. Whether Texaco, BP or anywhere else around Llangwm, the situation is identical.
What it means: this is the ideal spot to find out. Still in your tank, with no fuel pulled through: that is where the AdBlue sits.
What to do: do not get back in and crank it to clear the pump. Get the staff to help rolling it into a bay, save the bottle, then phone us from there. If it can't be moved, it can be emptied at the pump: the equipment is explosion-proof and fine on a busy forecourt.
At home in Llangwm with AdBlue in the diesel tank
Several days had passed with the dash light on. You bought a bottle, poured it in on the drive, and only when you put the empty bottle in the recycling did you look again at the cap. Just off Mill Street is not different from anywhere.
Put simply: if the vehicle hasn't been driven since, it is nearly as good as spotting it at the pump. AdBlue does not mix with diesel; it sinks to the bottom of your tank and waits there. Overnight doesn't change that.
Keep your keys indoors tonight — or a person may take it away first thing — and call us. We drain the car on your driveway, whether that is in Llangwm or out in Guildford. The pumps are quiet enough to use outside a house at night.
On the road around Llangwm with AdBlue in a diesel
Topped up, pulled away, and soon your engine was turning unevenly, blowing smoke, losing power, or lighting up the dash. Anywhere on Pill Parks Way or on the road to St Davids — under 25 miles away.
Meaning? The fuel pump has sucked the AdBlue in. It has been through your filter and your lines and, the further you went, into the high-pressure fuel pump and the injectors. It travels deeper with each mile driven and every restart.
What to do: pull over where it is safe to do so then switch off. Llangwm lies under 50 miles from the M4; there, pull off at the first junction rather than pushing on for the services. No trial restarts: clearing isn't something AdBlue will do. Phone, and say how far the car went.
Hire, lease or company car with AdBlue in the wrong tank
It's a vehicle you have had for a week. Your own vehicle either has no AdBlue or puts it elsewhere, so nothing told you the AdBlue cap sits just next to your diesel. Anywhere you happen to be around Pembrokeshire, every motorist can be caught.
The upshot: just as above, split by whether it ran, only with one added step. Many hire and company agreements want the owner to approve work on the car.
What to do: ring the hire firm or your fleet manager first, then us. That's quicker settled before we turn up than after. Hanging on for an answer at the car park at Johnston, or near Adeilad Clwb Rygbi Llangwm? Keep the car off throughout.
Not sure it was AdBlue in your diesel tank, Llangwm?
At times the fair answer is "I think so". A faint ammonia-like smell hangs around your filler, the bottle seems too light, and which cap came off is a blur. Maybe it happened in a hurry at the school gates at the local primary school, or on a friend's drive in Deerland.
In short: spillage near the filler leaves the motor no harm. The diesel tank with AdBlue inside is a different matter. Any AdBlue in that tank would be pulled in by turning on your car, and the start would not settle which it is in any case.
Next: act as though it got in, and leave your engine off. Phone and give what you saw: we'd sooner confirm a tank free of AdBlue than drain one after your motor has run.
The common ground in each Llangwm AdBlue drain
Each case has the same start to the job. Three things come when our technicians arrive — on a forecourt, a drive, a road beside The Hanging Stone or the car park at The Cottage Inn: the liquid, the amount, and if it has run. Those replies settle the work, and you hear our quote by phone, before anyone sets off.
Then that tank is drained and your system cleaned 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. Then is your filter — cleaned, or swapped where needed — then fresh diesel, and a test of the car. Where the motor hasn't run, expect about half an hour once we arrive, for most cases.
Starting the engine comes at the end. Our technicians check it runs properly on fresh diesel before we go. When it's caught early, the car very rarely has long-term damage, and the whole job happens where it is. Payment is that day, never in advance. For the insurer, there is a VAT invoice plus a report from the engineer. Plenty of insurance policies include misfuelling, and so check yours as we head over.
