What Now? AdBlue in the Diesel Tank in Tre-boeth

One fact matters above all once AdBlue is in a diesel tank, and that is whether your motor has been started since. If it has not, keep it that way, whether the vehicle is in Tre-boeth itself or out in Penfilia. Keep nothing on, call 0333 366 0103, and count on a thorough flush after a drain, carried out right where the car sits around Tre-boeth. If it's run, stop as soon as it is safe then switch off. A bigger job, yes, yet the same first move.

Below: the situations our technicians see, wherever around Swansea. Choose the one that fits.

AdBlue in a diesel on a Tre-boeth 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. Be it Texaco, Murco or anywhere else in Tre-boeth, the situation is the same.

Meaning? Spotting it here is as good as it gets. The AdBlue is in your tank and nowhere else. Nothing has pulled it in.

Freeing the petrol pump is no excuse to run it — so don't get back in. Ask the staff to help you roll the vehicle into a parking bay, keep the receipt or the bottle, and phone us from the forecourt. If it cannot be moved, it can be cleared at the petrol pump: the equipment is explosion-proof and fine on a busy forecourt.

Tre-boeth, at home: AdBlue in the diesel tank

Several days had gone by with the warning light on. Picked up a bottle, tipped it in outside the house, binned the empty — and only then checked the cap again, after the fact. Just off Moriah Road is no different from any other place.

What it means: if you have not driven since, this is nearly as good as the forecourt. As it is reluctant to blend, AdBlue drops to the base inside the tank and stays. A night parked changes none of that.

Your move: keys in the house, and so no one drives the vehicle off first thing. Then, ring. Your drive is where it is drained, be it in Tre-boeth or Waun-Gron. Late-night drains beside a house are fine: the pumps are quiet.

Tre-boeth: drove off with AdBlue in a diesel?

Filled up, pulled away, and soon your engine was running unevenly, smoking, down on power, or lighting up the dash. Perhaps it was on New Road, possibly on the way out towards Swansea, under 3 miles away.

In short: the AdBlue has been sucked through your fuel system. Mileage decides how far it gets: filter and lines to begin with, then the injection pump and each injector. Every restart, like every mile, pushes it on.

Next: pick a safe spot, pull in, and turn your engine off. Leave at the first junction — not the services further along — if you're on the M4, under 3 miles from Tre-boeth. Do not restart the car to see if it has cleared; it will not have. Tell us know the mileage driven as you call.

AdBlue in the wrong tank: hire, lease and company cars

You've only had this car a week. On your own car, AdBlue is missing or elsewhere. On this one, the inlet is right next to your diesel inlet — news to you. Anyone, wherever across Swansea, could do the same.

What it means: the same as the scenarios above, depending on whether it's run, with one more step. Many rental and fleet contracts need the owner's sign-off for repairs.

What to do: call the hire firm or your fleet manager first, then us. That is quicker settled before our technicians arrive than after. Keep it switched off as the answer comes, even if you're waiting outside Swansea or near Morris Castle.

AdBlue in your diesel tank? Not sure, around Tre-boeth

Occasionally the honest answer is "I think so". Which cap was taken off, you cannot recall; meanwhile the bottle weighs lighter than expected, and a whiff of ammonia hangs by the filler. The gates of the local primary school in a rush, perhaps, or someone's driveway out in Mynydd-Garn-Lwyd.

What it means: a little spilled round your filler does no harm to the motor. In the diesel tank, by contrast, AdBlue harms it. If there is AdBlue in the tank, starting the vehicle would suck it in, and it would not tell you which either.

Your move: behave as though it got in, and don't start your motor. Ring and give the details: we'd rather find a tank free of AdBlue than drain one after the engine has been run.

The common ground in every Tre-boeth AdBlue drain

Whatever the case, a single opening is used. Wherever the car stands — The King's Head Pub's car park, a street beside Penlan Leisure Centre, a drive, a forecourt — the van arrives and we ask for the fluid, the amount, and whether your motor has been run. Answers shape the work; the price comes on the call whilst nobody has left yet.

Draining that tank comes first, followed by a full flush — more vital after urea than with petrol, because crystals and corrosion will not go on their own, however long it sits. Then comes your filter — flushed, or swapped when needed — then clean diesel, and a test of your car. The majority of unrun cars are a half-hour visit after the moment our engineers get there.

We start the car last. Our test that it runs correctly on clean diesel comes before our technicians leave. The entire job is done where the car is, and when it is spotted quickly, long-term damage is very unusual. For your insurer: the engineer's report and the VAT invoice. For you: payment that day, nothing in advance. Check your insurance before we're en route: misfuelling cover comes built into plenty of policies.
