What Now? AdBlue in the Diesel Tank in Bigyn
Everything turns on one detail: if the engine has been run after the AdBlue was added — far more than anything else. Anywhere your car is — Llanelli, Bigyn — never start a motor that has not been started yet. Keep nothing on, ring 0333 366 0103, and expect a proper flush after a drain, done just where the car sits around Bigyn. If it has run, stop as soon as it is safe then switch off. The job is bigger, yet the first step is the same.
Compare what happened to a situation from the list below, wherever across Carmarthenshire you happen to be.
AdBlue in a diesel on a Bigyn 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. Somewhere around Bigyn, then — Asda, BP, or anywhere else nearby.
The upshot: of every spot to find out, the forecourt is the best. No pump has drawn it in, so the AdBlue stays only in that tank.
Your move: keep out of the car, however much the queue needs clearing. Get the staff to lend a hand pushing it to a bay, save the bottle, then phone us right there. If it can't be shifted, it can be drained at the petrol pump: the equipment is explosion-proof and fine on a busy forecourt.
AdBlue in your diesel tank at home in Bigyn
On your dash, a reminder had been lit all week. Only by the recycling, the empty container in your hand, did you look back at the cap you'd opened on the driveway. Just off Pen-y-Bigyn is not less likely from anywhere.
The point: zero miles since leaves it nearly equal to spotting it at the pump. At the bottom of your tank is where AdBlue stays, because it won't mix with diesel — and a night going by makes nothing of the difference.
What to do: leave your keys inside the house so nobody moves your car in the morning. Then call. Your driveway is where it gets drained, whether in Bigyn or Wern. Late-night clears beside a house are fine: the pumps are quiet.
AdBlue in a diesel and already driving around Bigyn?
Rough running, smoke, lost power or a glowing dashboard started a short way after the top-up. Anywhere along Y Bwthyn or on the road towards Swansea — under 10 miles away.
The point: the system has pulled AdBlue in by now. It's been through the fuel filter and the lines and, the further you went, into your high-pressure pump and the fuel injectors. It travels deeper with each mile covered and every restart.
Next: pick a safe spot, pull in, then switch the engine off. Bigyn lies under 5 miles from the M4; there, come off at the first junction rather than pushing on for the services. No trial starts: clearing is not something AdBlue will do. About what distance had it gone? Tell us when you call.
A hire or company car with AdBlue in the wrong tank?
You've had the car barely a week. On your own car, AdBlue is absent or somewhere else. On this one, the cap is right next to your diesel inlet — news to you. Wherever you happen to be across Carmarthenshire, every motorist can be caught.
Put simply: one extra step on top of the situations above, which turn on if it has run. Many rental and fleet agreements require the owner's approval for work.
Next: ring the hire company or the fleet manager first, and then us — settling it before our arrival is quicker. Waiting for an answer in the car park outside Llanelli, or beside Elim Pentecostal Church? Leave your engine off meanwhile.
Bigyn: unsure whether it was AdBlue in your diesel tank?
"I think so" is often the most honest answer there is. A slight ammonia-like smell lingers around the filler, the bottle seems too light, and the cap you took off is hard to recall. The gates of the local primary school in a hurry, say, or someone's driveway over in Seaside.
In short: a spill near your filler leaves the motor no harm. Once it's inside the diesel tank, though, it does. You can't tell which by turning the key, and doing so would draw in any AdBlue that is in your tank.
Assume it went in, and never turn your key. Call us and explain what you saw; we would rather check a tank that turns out clean than drain one that has already been run.
What every AdBlue drain in Bigyn has in common
The work opens the same way, whichever the case. We come to the vehicle, whether it's at a forecourt, a drive, the car park at The Duke of Wellington Inn or a side street close to St Barnabas Community Hall, and ask three things: what was put in, roughly how much, and if the motor has been run. On the phone, before dispatch, you hear the quote, and those answers decide the work too.
AdBlue forms crystals and eats at some metals in fuel systems, so it does not wash out unaided; that's why the flush, after the drain, counts much more with AdBlue than with petrol. Finally are your filter, cleaned or renewed as needed; fresh diesel; and a test of the car. If your engine hasn't run, most jobs take about half an hour once we're there.
The last step is firing it up. With fresh diesel in, it runs while our technicians make sure it is running smoothly, and then we leave. The entire job is done where the car is, and when it is noticed quickly, long-term damage is very rare. Nothing is taken upfront, payment happens on the day, and you receive what your insurer wants: an engineer report plus a VAT invoice. Worth remembering: many insurers include misfuelling cover, and so a check of your policy as we travel is worthwhile.
