Poundffald: AdBlue in the Diesel Tank? Leave It Off

With AdBlue in the diesel tank, your ignition stays off and so does your motor. Urea dissolved in water is what AdBlue is. The harm begins once it's sucked through your lines — it will not burn, and it won't combine with diesel. A drain and a thorough flush, done where the car is in Poundffald, is generally all AdBlue in a diesel tank needs — if it's caught before your motor has run. Before anything, ring us on 0333 366 0103.

Your next steps straight away, Poundffald: AdBlue in the diesel tank

Things to do:

  • So nobody can turn your ignition on, take the keys away.
  • Put the hazard lights on if you're anywhere close to moving traffic.
  • So you can tell us which liquid it was and about how much, keep your receipt or the empty bottle.
  • Our van locates you fastest with a postcode starting SA4 3, or just the name of a street close by, so call from the spot.

Not to do:

  • Moving your vehicle just a few yards is no reason to fire up your engine.
  • The ignition stays off: on many diesels, turning it on is enough to run the pump.
  • Do not top up with diesel to dilute it. AdBlue does not dilute in diesel; it separates out.
  • Even a short distance along Tirmynydd Road is too far to drive the vehicle.
  • Beside the road, do not try draining it on your own.

Moving your vehicle off the island is a job for staff to help with, wherever Poundffald forecourt you are on, the Tesco or any other. Parked on your own drive? Then it stays just as it is.

AdBlue in a diesel tank: what it does

Not the engine but the exhaust is where AdBlue is meant to go. Its own tank holds it, and from there it's sprayed into your exhaust, and there it treats the fumes. Not one side fits the other: urea doesn't belong in a pump, and a pump can't take urea.

Fuel mixes; AdBlue, after tipped in, will not. Its behaviour is not at all like diesel's. The intake takes fuel from the deepest part of that tank, and that is precisely where AdBlue ends up: as it is denser than diesel, it sinks. Once your system runs, the AdBlue is first to be pulled through. Before then it sits underneath your diesel, which is how a vehicle topped up in Fairwood yesterday and never started stays the simple case, provided nobody touches the key.

Two kinds of harm follow from there. 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 parts it reaches for as long as it stays there. A vehicle left standing around Poundffald with AdBlue already in its lines is worse by the morning; one with AdBlue just in its tank is not. Diesel protects the high-pressure pump and each injector as it passes; water offers none of that, which is a separate form of harm.

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

Petrol pumped into a diesel on Esso's forecourt makes your fuel thin — that's the whole fault. Blended into the diesel and left unused, it is harmless for now; running your engine is the harm.

AdBlue in a diesel is another problem: not thin fuel, yet no fuel at all. It does not burn, so it can't just be run through. It doesn't stay mixed, and so it can't be diluted. And crystals and corrosion don't wash out with the next tank of fuel. That is why the flush counts more with AdBlue than with petrol, and why starting the engine "to see" costs more here than almost anywhere else, whether your car is in Blue Anchor or the middle of Poundffald.

As with petrol, there's good news. Emptying a tank is the easiest part on a fuel system, and without start-up, the AdBlue stays in it — wherever in Swansea the vehicle sits.

AdBlue in a diesel tank around Poundffald: how it ends up there

In dim light, two caps side by side — the AdBlue one and the diesel cap, occasionally under one flap — may appear the same. No one means it; many layouts invite it. Mostly it takes place with a bottle bought on the way home and poured in on the driveway, not at the pump.

The ways it occurs are few and familiar. Hurrying, outside the local primary school, after a warning light flashed on during the school run, a parent refills the vehicle. After work, a bottle is tipped in on a drive close to Joiners Road. Or a driver unfamiliar with that flap refills your vehicle after dark, parked in the car park outside The Poundffald Inn.

It occurs most in the motors motorists know least: a hire car, a new motor, a company car, or the second vehicle of a household with one diesel and one petrol. Wherever you are in Poundffald or the remainder of Swansea, it is the same mistake and the same first answer: leave it off.

AdBlue in the diesel tank around Poundffald, and your engine started?

The AdBlue has left that tank, then. The fuel filter and lines have had it pulled along, and some running time carries it on to the injection pump and each injector.

You may notice the engine running roughly, smoking, losing power, showing warning lights or cutting out, possibly on the way back from Crwys Bank or halfway across Poundffald. Stop as soon as it is safe, switch off, and don't restart the vehicle to check. With each start, more of it is pulled through.

Leave the M4, under 5 miles from Poundffald, at the next junction and stop safely, rather than driving on.

Distance counts: each mile carries the AdBlue further in, so heading towards Swansea, under 10 miles away, makes a much bigger job than hopping across Poundffald to the car park by Gower Fresh Christmas Trees. Tell us about how far it had come.

There is more to clean out once your engine has been started, and we do all of it where the vehicle has come to a stop. Very seldom does it leave long-term damage if it is caught early.

What emptying AdBlue from a diesel involves in Poundffald

Our technicians come to your car, wherever it has stopped in Poundffald: a side street close to Capel y Crwys, a drive, a lay-by or a forecourt. What was put in, about how much, plus whether the engine has been run: our engineers check first, since those shape the work.

Next, emptying your tank right there takes out the polluted diesel along with the AdBlue in one go. Residue from AdBlue will not wash out unaided, and so the fuel system gets a full flush, which matters far more here than with petrol. A test of your car comes last, after clean diesel is added and the filter is cleaned or, where needed, replaced. Engine not run? In that case count on about half an hour once we are there for most jobs. The pumps are explosion-proof, fine on a working forecourt and quiet enough to use outside a house at night.

The last step is to bleed the system on clean diesel. Whether it is a parking bay at Gowerton or a drive around Poundffald, that is where our technicians start it and you head off. It is tested on fresh diesel to be sure it runs smoothly before our engineers leave. Our engineers do it all wherever the vehicle has stopped, and it never has to be taken to a garage. Afterwards, there is the paperwork for the insurer: a VAT invoice and a written report from the engineer.

Poundffald and Swansea: AdBlue drains across the area

Three Crosses, Wernbwll and Wern-olau are among the places around Poundffald that the same vans reach, together with much of Swansea beyond, over the SA postcode area. Near a boundary, or somewhere tricky to pin down? Checking beats guessing, and so phone.

Poundffald is a residential suburb, and a call-out drain suits it: whether the car is on a home drive, a residential street, a car park or a forecourt, our engineers drain it where it stands, so it never needs to be moved to us.

What AdBlue in a diesel tank costs to put right in Poundffald

Each job is different, and so not one single quote is honest. What moves the cost is, firstly, whether the engine has been running and for how long; then how much AdBlue got in; and finally where your car is and whether a van can reach it safely, which is simpler on an open driveway than in a tight spot behind Old School House.

For that in mind, every call from Poundffald begins with the identical trio — which fluid went in, how much, if the engine ran — ahead of a figure. Those answers turn a range into a straight quote.

Quoted on the call before the engineer heads out, the job is settled that day — card or phone, nothing in advance. Look at your insurance while we are on the way: many include misfuelling cover.
