Harbour Village: AdBlue in the Diesel Tank? Leave It Off

AdBlue in your diesel tank? Then keep the motor off — and your ignition too. In plain terms, AdBlue is just urea in water. It doesn't burn, it does not mix with diesel, and the harm it does starts when the fuel system pulls it in. If the motor hasn't run yet, AdBlue in a diesel tank is usually emptied and thoroughly flushed where your car sits in Harbour Village. Before you do anything else, phone 0333 366 0103.

Harbour Village, AdBlue in the diesel tank: what to do right away

Things to do:

  • Take your keys out, so no one switches your ignition on.
  • Hazards on, if moving traffic is anywhere near.
  • Which fluid, and about how much quantity? Save the bottle or the till receipt, and we can see.
  • Ring us from where you are. A postcode starting SA64 0, or the name of the nearest street, brings the van to you without a search.

Not to do:

  • Shifting the vehicle just a short way is no reason to start the motor.
  • The ignition stays off: on many diesels, turning it on is enough to run your fuel pump.
  • No extra fuel added. The AdBlue will not mix, so it's pointless.
  • Do not drive the vehicle anywhere, not even a short distance up New Hill.
  • Emptying that tank on your own beside the road isn't one to try.

Ask the people behind the counter to help you move your car off the island if you're on a forecourt in Harbour Village, whether it is the Esso or somewhere else. If you are on your own drive, leave the vehicle just where it stands.

AdBlue in a diesel tank, and what it does there

Not your motor but the exhaust is where AdBlue is meant to go. Its own tank keeps it, and from there it's fed into the exhaust, where it treats the fumes. A fuel pump is not made to take it, and AdBlue was never intended to go through one.

Fuel blends; AdBlue, after tipped in, will not. Its behaviour is not at all like diesel's. Heavier than diesel, it drops and collects underneath it — the very spot the intake sucks from. The first thing the fuel system pulls through, after it runs, is the AdBlue. So a car that had AdBlue poured in on a drive in Dyffryn last night, and has not been started since, is still the easy case: the AdBlue is lying at the bottom of that tank, and nothing has sucked it in.

Two kinds of harm follow from there. Crystals and corrosion. As the water evaporates, it leaves urea that crystallises in filter elements and narrow passages; and, since it attacks certain metals, every part it touches suffers for as long as it stays in there. Pipes carrying AdBlue mean harm by morning for a vehicle parked around Harbour Village. Just inside that tank, it stays the same. Diesel protects the high-pressure pump and every injector as it flows; water gives no lubrication, and that is a separate kind of harm.

Draining AdBlue from a diesel tank in Harbour Village

Why is AdBlue in a diesel frequently the bigger issue?

Put petrol in a diesel at the another forecourt nearby and you have an issue of thin fuel. No damage is done while it stays unused, blended into the diesel — only when the motor works on it.

AdBlue in a diesel is a problem of the wrong substance altogether. Because it doesn't burn, running it through isn't an option. Crystals and corrosion stay after the following tankful, and AdBlue separates again from the diesel, and so watering it won't work. That is why the flush counts so much, and trying the engine "to see" costs more with AdBlue than nearly any other slip — in Penyraber or the centre of Harbour Village equally.

With AdBlue, the good news is no distinct from petrol. Anywhere in Pembrokeshire the car has stopped, an unstarted motor means the AdBlue yet inside the tank: the easiest part of any fuel system to empty.

How AdBlue ends up in a diesel tank around Harbour Village

Many vehicles place the AdBlue filler alongside the diesel one, occasionally under one flap, and after dark the two may look identical. Nobody means it. It mostly occurs at home, from a container bought en route home, not at the forecourt.

The ways it takes place are few and familiar. The refill gets rushed outside the local primary school, because your dash lit up with a warning while the kids were dropped off. Close to Clement Road, someone pours a bottle in at home in the evening. Another pattern: dim light, the car park by Rose and Crown, and a driver opening that flap for the first time.

It happens most in the cars drivers know least: a hire car, a new car, a company car, or the second motor of a household with one diesel and one petrol. Leave it off: that is the first response to the same mistake, wherever in Harbour Village or the remainder of Pembrokeshire you are.

AdBlue in your diesel tank around Harbour Village, and your engine started?

In that case, the AdBlue is no longer in that tank. The fuel filter and pipework have had it pulled through, and some running time carries it on to the high-pressure pump and each injector.

Maybe coming back from The Rec, or part way across Harbour Village, your engine may run rough, smoke, lose pace, light up the dash or stall. Stop as soon as it is safe, switch off, and don't restart the vehicle to check. Each start pulls more of it through.

Harbour Village sits under 50 miles from the M4; if you were on it, leave by the first junction and stop somewhere safe rather than driving on.

How far it went counts. A couple of hundred yards across Harbour Village to the car park by Ocean Lab is a very different job from a run towards St Davids, under 15 miles away, with the AdBlue reaching further into the system with each mile. Roughly how far had it come? Tell us.

We do all of the rinsing where the vehicle has ended up, and once your engine has been started there is more of it. Spotted early, it very rarely leaves permanent damage.

What does an AdBlue drain on a diesel involve in Harbour Village?

Anywhere it has stopped around Harbour Village — a forecourt, a layby, a driveway, a road beside Phoenix Community Centre — the van travels to the car. Before anything else we ask what went in, about how much, and whether the motor has been run, because those replies settle the work.

The polluted diesel and the urea leave as one after that tank is emptied, on the spot. With AdBlue, more so than with petrol, the flush matters: the whole system is flushed all the way through since what remains won't flush out by itself. Your filter is flushed, or replaced where it needs to be; fresh diesel goes in; and your car is tested. The majority of these jobs are a half-hour job once our engineers get there, if the motor hasn't run. Explosion-proof pumps make a busy forecourt safe to work on, and they're quiet enough not to disturb the neighbours at night.

Lastly, the fuel system is primed with new diesel. Whether it is a parking space outside Fishguard & Goodwick or a drive in Harbour Village, that is where our technicians fire it up and you set off. It is checked on fresh diesel to be sure it runs properly before our technicians head off. Since the job is done in full where the vehicle is, a garage never comes into it. You get a VAT invoice and an engineer report later on, which is what insurers want.

Harbour Village and Pembrokeshire: AdBlue drains across the area

Harbour Village is a coastal area, and a call-out drain suits it: whether the vehicle is on a home drive, a residential street, a car park or a forecourt, we drain it where it is, and so it never needs to be shifted to us.

Harbour Village: what AdBlue in a diesel tank costs to fix

Not one flat price would be honest, since each job is different. What shifts the price is, first, whether the engine has been running and for how long; then how much AdBlue got in; and then where the vehicle is and whether a van can reach it safely, which is simpler on an open driveway than in a tight gap behind Garnwnda Burial Chamber.

That's why each call from Harbour Village starts with the same three questions, asked before giving a figure, not after: what went in, how much, and if it has run. Their answers narrow a range down to one number.

Before a van sets off, you are told our price by phone. Then you pay on the day, card or by phone, with nothing upfront. Misfuelling cover is part of plenty of insurance policies, so it pays to look at yours before the van arrives.
