AdBlue in a Diesel Tank in Pentre Meyrick? Don't Start It

If AdBlue has got into your diesel tank, keep your engine off and keep your ignition off. Water with urea dissolved in it: that is AdBlue. The trouble starts once it is sucked through your lines — it will not ignite, and it won't blend with diesel. In Pentre Meyrick, AdBlue in a diesel tank caught before your motor runs usually means a drain and a thorough flush, just where your car is. Call 0333 366 0103 before you do anything else.

AdBlue in your diesel tank around Pentre Meyrick: the first few minutes

Do:

  • Pocket your keys, which stops anyone turning the electrics on.
  • Hazards on, if moving traffic is at all close.
  • Which product, and roughly how much volume? Save the bottle or the receipt, and we can see.
  • Call just where you are. Quote a CF71 7 postcode or the closest street name, and nobody has to search for you.

Never:

  • Don't start the motor, even for a moment to shift the car.
  • Many diesels power their pump the instant your ignition comes on, so keep the car off.
  • Adding extra diesel does not work: AdBlue settles out rather than thinning.
  • Even a short way up Nash View is too far to drive it.
  • Draining that tank yourself beside the road is not one to try.

The attendants working at any Pentre Meyrick forecourt — the Texaco among them — will normally help rolling it aside if you ask. If you're on your own drive, leave the car precisely where it stands.

What does AdBlue do in a diesel tank?

AdBlue is made for the exhaust, not the motor. It goes into its own tank and is sprayed into your exhaust gas to fresh it. Nothing inside a fuel pump is made for this liquid — and no part of that was intended to go that way.

Inside a diesel tank it acts very differently from fuel. It doesn't mix in. The pickup takes fuel from the deepest part of the tank, and that's precisely where AdBlue settles: as it is denser than diesel, it sinks. A car topped up on a driveway in Graig Penllyn yesterday evening and left unstarted is the simple one. Nothing has sucked the AdBlue up so far — but once your engine runs, that's what goes first, straight from the bottom of the tank.

From there it does two kinds of harm. As its water goes, the urea left behind crystallises, and the crystals block filters and settle in fine passages. And it's corrosive to some of the metals a fuel system is made from, so it keeps running on the components it reaches for as long as it remains there. A vehicle left sitting in Pentre Meyrick with AdBlue already in its lines is worse by the morning; one with AdBlue just in its tank is not. Diesel protects the injection pump and every injector as it flows; water offers none of that, and that is a separate kind of damage.

Draining AdBlue from a diesel tank in Pentre Meyrick

AdBlue in a diesel: why it's often worse than petrol

Petrol pumped into a diesel on another forecourt nearby's forecourt leaves the fuel watery — that's the main fault. Blended into your diesel and left unused, it is no threat for now; using the motor is the harm.

The issue with AdBlue in a diesel is a completely unsuitable substance. It doesn't burn, so it can't simply be run through. Nor can it be watered down, since it separates again — and the following fill won't rinse away crystals or corrosion. So the flush counts more here, and turning the key "to see", in the centre of Pentre Meyrick or out in West Village, does more harm than nearly any other mistake.

The good news is the same as with petrol. Clearing a tank is the simplest job on any fuel system, and with no start-up, the AdBlue stays in it — wherever across The Vale of Glamorgan the car sits.

How does AdBlue end up in a diesel tank in Pentre Meyrick?

Nobody means to do it. The AdBlue filler on many motors waits right next to your diesel filler, occasionally under the same flap, and the two caps can look alike in poor light. A bottle bought while driving home and tipped in outside the house, instead of at the forecourt, is the typical story.

It tends to happen in a couple of familiar ways. The refill is rushed outside the local primary school, because the dash flashed with a warning while the kids were taken in. After work, a container is tipped in on a drive near Clos Meurig. Or the vehicle is topped up in the car park at The Red Fox, in poor light, by a person who has never opened that flap before.

The least familiar vehicles see it the most — rentals, new cars, company ones, and the spare car in a home with both fuels. An identical slip, same first step — keep it off — anywhere you happen to be around Pentre Meyrick or the remainder of The Vale of Glamorgan.

Started the motor with AdBlue in your diesel tank around Pentre Meyrick?

If so, the AdBlue is no longer in the tank. Your filter and pipework have had it pulled through, and any running carries it on to the injection pump and each injector.

You may notice your engine running unevenly, smoking, losing power, showing warning lights or cutting out, possibly on the way back from Coed y Castell or halfway across Pentre Meyrick. No restarting to check: pull over once safe, then switch everything off. Each start pulls more of that through.

Pentre Meyrick sits under 3 miles from the M4; if you were on it, exit by the next junction and stop safely instead of carrying on.

How far it went matters. A few hundred yards across Pentre Meyrick to the car park by St. Tydfil's Church is a very different job from a run towards Cardiff, under 15 miles away, with the AdBlue reaching further into the fuel system with each mile. Tell us about how far it had come.

There's more to clean out once the engine has run, and our technicians do all of it where the vehicle has stopped. Noticed soon, it very seldom leaves lasting damage.

What does an AdBlue drain on a diesel involve around Pentre Meyrick?

The car stays where it is, whether that's a road beside St John the Baptist, a driveway, a layby or a forecourt in Pentre Meyrick, and our van comes to it. Which fluid was put in, roughly the quantity, and whether the engine has been run: our technicians ask before all else, since those shape the work.

On the spot, that tank is then emptied, and all of the contaminated diesel and the urea leave at once. Residue from AdBlue will not flush away by itself, and so the fuel system gets a careful flush, which matters much more with urea than with petrol. Next, your filter: cleaned, or replaced when it must be. Then fresh diesel, then a test of the vehicle. About half an hour on site is usual for most jobs when the motor has not run. Explosion-proof pumps make a busy forecourt safe to work on, and they run quiet enough not to disturb the neighbours at night.

New diesel goes in to prime your system, and that's the final step. Firing it up comes next, and then you head off from where your car is parked, outside Pencoed or on a drive around Pentre Meyrick. Before we leave, our engineers check it's running smoothly with new diesel in. The entire job is done where the vehicle is, so it never needs to be taken to a garage. The insurer is likely to want an engineer's report and the VAT invoice — both yours afterwards.

AdBlue drains across The Vale of Glamorgan, Pentre Meyrick included

AdBlue call-outs around Pentre Meyrick go to teams that cover the places near it — Penllyn, Llysworney as well as Llangan — and most of The Vale of Glamorgan beyond, across CF postcodes. Ring and ask rather than guess if you're by a county line, or anywhere tricky to explain.

Wherever your car stands — your driveway at home, a residential street, a parking area, a filling station — our engineers empty it on the spot, with no need to bring it to us; which suits Pentre Meyrick, a rural hamlet, well.

What does AdBlue in a diesel tank cost to sort out in Pentre Meyrick?

There is no honest single price, since the jobs aren't the same. The price changes first with how long, if at all, the engine has been running, and next with the quantity of AdBlue that went in. After that it turns on where the car is and whether our van can reach it safely, which is easier on an open drive than in a tight space behind Colwinston Community Centre.

For that in mind, every enquiry from Pentre Meyrick opens by asking the same trio — what got in, how much, if the engine ran — before a quote. Their answers shrink a range right down to a single figure.

Quoted on the call before the van sets out, the job is paid for on the day — card or phone, no deposit. Many insurance policies include misfuelling cover, and so it is worth checking yours whilst we are on the way.

Pentre Meyrick: still next to the car?
