Don't Start It: AdBlue in a Diesel Tank in Llangynidr

AdBlue in the diesel tank? Then keep the motor off — and your ignition as well. AdBlue is urea dissolved in water. The trouble begins once it's sucked through the lines — it won't burn, and it won't combine with diesel. In Llangynidr, AdBlue in a diesel tank found before the motor runs usually comes down to a drain and a thorough flush, right where the car is. Ring 0333 366 0103 before you do anything else.

Those opening minutes: AdBlue in your diesel tank around Llangynidr

To do:

  • Take the keys out, and so no one switches your ignition on.
  • If you are at all close to moving traffic, put the hazards on.
  • Keep the till receipt or the empty bottle, and so you can tell us what was put in and about how much.
  • Tell us a postcode starting NP8 1, or whatever street is nearest, and the van finds you directly — so ring wherever you stand.

Do not do these:

  • Don't start your motor, even for a moment to shift the vehicle.
  • Don't switch the ignition on. On many diesels that alone runs the fuel pump.
  • AdBlue doesn't mix in diesel — it separates out — so adding more fuel will not weaken it.
  • Even a short distance along Forge Road is too far to drive the car.
  • Draining that tank yourself by the road is not worth trying.

Moving your car off the pumps is a job for attendants to help with, wherever Llangynidr forecourt you are on, the Gulf or any other. If you're on your own drive, leave the vehicle just where it sits.

What AdBlue does in a diesel tank

Not your engine but your exhaust is where AdBlue belongs. It goes into its own tank and is sprayed into the exhaust gas to clean it. No part in an injection pump is made for this liquid — and none of it was intended to go through one.

It doesn't combine. Once it's poured into a tank of diesel, AdBlue behaves nothing like diesel. Heavier than diesel, it sinks and collects underneath it — the very place the pickup sucks from. Simplest of all: one that got AdBlue in Cyffredyn last night and has not turned since. The AdBlue waits at the foot of the tank, undrawn — but it will be first through if the motor starts, before any diesel at all.

It causes two kinds of harm from there. What is left once the water evaporates is urea, which turns into crystals: they lodge in tiny channels and block filters. On top of that, it attacks some metals in the fuel system, and carries on until it is cleared out. If the AdBlue is in the lines, leaving it overnight around Llangynidr leaves things worse. In that tank only, time costs nothing. Diesel protects the high-pressure pump and every injector as it flows; water offers no lubrication, which is a separate form of damage.

Petrol or AdBlue in a diesel: why AdBlue is frequently worse

Put petrol in a diesel at the Asda Express and you have an issue of thin fuel. Blended through the diesel and left unused, it is harmless for now; running the motor does the harm.

AdBlue in a diesel is another problem: not thin fuel, yet no fuel at all. It doesn't burn, and so it cannot just be run through. Whether your vehicle sits in Bwlch or the centre of Llangynidr, turning it over "to see" does more harm in this case than nearly any other error, and the flush matters more. The reasons: it won't stay blended, so diluting it fails; and deposits and corrosion survive the next fill.

With AdBlue, the good news is no different from petrol. Wherever around Powys your vehicle has come to rest, an unrun engine leaves the AdBlue still in the reservoir: the easiest bit of any fuel system to empty.

How does AdBlue end up in a diesel tank in Llangynidr?

It is not deliberate. Plenty of cars keep the AdBlue inlet beside the diesel inlet, occasionally under a single flap, and muddling them up is simple in poor light. It mostly happens at home, from a container bought en route home, rather than at the filling station.

A couple of familiar ways cover the majority of them. A warning light comes on during the school run, and the top-up happens in a hurry outside the local primary school. A driver pours the container in at home, right off Cwm Crawnon Road, as the day ends. Or the vehicle is topped up in the car park outside The Red Lion, in poor light, by a person who has never opened that flap before.

The least known cars get it the most — rentals, new ones, company cars, and the spare motor in a family with both fuels. Keep it off: that's the first response to the same slip, wherever in Llangynidr or the remainder of Powys you are.

Started the motor with AdBlue in your diesel tank in Llangynidr?

Then the AdBlue has left the tank. Via the fuel filter, through the pipework, and — given any running — on to the high-pressure pump and every injector: that's how far it has gone.

Perhaps returning from Coed Banal-mawr, or part way across Llangynidr, the engine may go rough, smoke, lose pace, flash the dash or stall. Once safe, stop and switch it off — with no turning it on again to see. Each start pulls more of that through.

Llangynidr sits under 25 miles from the M4; if you were on it, leave by the next junction and stop safely rather than driving on.

A quick hop across Llangynidr to the car park by Castle Farm Stone is one thing; driving towards Newport, under 25 miles away, is something else, since every mile pushes the AdBlue deeper in. So mileage counts. Roughly how far had it come? Tell us.

We do all of the cleaning where the vehicle has stopped, and once your engine has run there is more of it. Spotted early, it very rarely leaves lasting damage.

Llangynidr: how AdBlue is cleared from a diesel

A road by Community Centre, a drive, a layby or a filling station: anywhere the vehicle has come to rest around Llangynidr, our technicians travel to it. Which fluid got in, about the quantity, plus whether your engine has turned over: we check before all else, since those decide the work.

Then your tank is drained where the vehicle stands, so the tainted fuel and the AdBlue come out together. A full flush counts far more with AdBlue than with petrol, since residue will not wash out by itself. Clean diesel goes in once your filter is flushed — or replaced, when it needs to be — and after that your vehicle is tested. If your motor has not run, the majority of jobs take about half an hour once our engineers arrive. The pumps are explosion-proof, fine on a working forecourt and quiet enough to use outside a house after dark.

Clean diesel goes in to bleed the fuel system, and that's the final step. You head off as soon as our engineers have started the engine, and it makes no difference whether the car is on a driveway around Llangynidr or in a bay outside Ebbw Vale Town. It is checked on fresh diesel to confirm it runs smoothly before our engineers leave. No workshop is required at any stage, with the entire job done on the spot. The insurer will want an engineer's report and your VAT invoice — each handed over once the job is done.

A mobile service suits Llangynidr, a village: you have no need to bring the car to us, since our engineers empty it on the spot, on a driveway, a residential street, a car park or a filling station.

AdBlue in a diesel tank in Llangynidr: the cost of fixing it

Not one single price could be honest, since each job differs. Whether the motor has run, and for how long, comes first in what changes the cost. How much AdBlue got in comes next, and then the position of the car, because an open driveway is simpler for a van to get to safely than a tight spot behind St Cynidr & St Mary.

Before any quote, never afterwards, every enquiry from Llangynidr begins with three questions: the fuel, the quantity, and whether it ran. The replies turn a range into a straight price.

Before a van sets off, you are told the quote on the phone. And payment is on the day, card or over the phone, with nothing upfront. Plenty of insurance policies include misfuelling cover, and so it's worth checking yours while we're on the way.
