AdBlue in the Diesel Tank in Gwaun-Cae-Gurwen? Keep It Switched Off
If AdBlue has gone into the diesel tank, keep your motor off and keep your ignition off. Water with urea dissolved in it: that's AdBlue. Not like fuel, it neither burns nor mixes, and no harm starts till the motor pulls it round. In Gwaun-Cae-Gurwen, AdBlue in a diesel tank found before the motor runs normally comes down to a drain and a thorough flush, right where the car is. Before anything, ring us on 0333 366 0103.
What to do right now, Gwaun-Cae-Gurwen: AdBlue in your diesel tank
Do:
- Pocket your keys, and that prevents someone switching the power on.
- If you are anywhere close to moving traffic, put your hazards on.
- So you can tell us which liquid it was and about how much, keep your receipt or the empty bottle.
- Call just where you are. Say a SA18 1 postcode or the nearest street sign, and nobody has to search for you.
Things not to do:
- Moving the car just a short way is no reason to start the engine.
- Turning your key to ignition alone sets the pump running on many diesels. Avoid it.
- Don't top up with diesel to dilute it. AdBlue does not mix in diesel; it separates out.
- Even a short stretch up Cefn Road is too far to drive the vehicle.
- Don't try to drain it yourself by the kerbside.
Moving your car off the pumps is a job for attendants to help with, wherever Gwaun-Cae-Gurwen forecourt you're on, the Texaco included. On your own driveway, do not touch it at all.
What does AdBlue do in a diesel tank?
Made for the exhaust, AdBlue has no place in the motor. It goes into its own tank and is sprayed into your exhaust gas to clean it. Neither side fits the other: urea does not belong in an injection pump, and an injection pump cannot deal with urea.
Poured in with your diesel, it stays apart instead of mixing — quite unlike fuel. It sinks, because it is heavier than diesel, and settles low where the pickup draws its fuel from. A motor topped up on a drive in Garnant yesterday evening and not started since counts as the simple case. No pump has sucked the AdBlue up so far — but once the engine turns, that's what is pulled first, directly from the bottom of that tank.
Once it is pulled in, the harm takes two forms. What is left when the water goes is urea, which turns into crystals: they lodge in narrow passages and clog filters. Worse, it eats at certain metals in a fuel system, and keeps going until it's flushed out. If the AdBlue is in the lines, leaving it till morning around Gwaun-Cae-Gurwen leaves things worse. Inside that tank alone, waiting does nothing. The water in it does harm of its own: the high-pressure pump and the fuel injectors rely on diesel to lubricate them, and water gives them nothing.
AdBlue in a diesel: why it's frequently worse than petrol
Petrol put into a diesel on Tout's's forecourt leaves your fuel watery — that is the whole fault. Blended through the diesel and sitting still, it's no threat at that stage; using your engine is the damage.
AdBlue in a diesel is an issue of the wrong substance altogether. Because it doesn't burn, running it through is not an option. Crystals and corrosion stay after the next fill, and AdBlue splits back out of the diesel, and so thinning it can't help. Hence the flush counts more, and turning the key "to see" costs more here than almost any other slip — in Lower Brynamman or the centre of Gwaun-Cae-Gurwen equally.
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 remains in there — wherever across Neath Port Talbot the vehicle sits.
How AdBlue ends up in a diesel tank around Gwaun-Cae-Gurwen
Plenty of motors put the AdBlue filler alongside the diesel one, occasionally behind one flap, and in dim light the two can look the same. Nobody means it. Most of the time it occurs with a bottle bought on the way home and poured in on the drive, 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 flashed with a warning as the children were taken off. A driver pours the container in at home, right off Water Street, as the day ends. Or the car is topped up in the car park at the pub in the village, in poor light, by a person who has never opened that flap before.
It occurs most in the vehicles drivers know least: a hire car, a new motor, a company car, or the second vehicle of a household with one diesel and one petrol. An identical slip, same first response — leave it switched off — anywhere you happen to be in Gwaun-Cae-Gurwen or the rest of Neath Port Talbot.
AdBlue in the diesel tank in Gwaun-Cae-Gurwen, and the motor started?
Then the tank is no longer where the AdBlue is. Your filter and lines have had it pulled along, and some running time takes it on to the injection pump and each injector.
Lumpy running, smoke from the exhaust, dropping power, dashboard lights or stalling: any may show up, maybe part way across Gwaun-Cae-Gurwen or returning from Ynys Dawela Nature Park. When safe, stop then switch it off — with no turning it on again to test. Each start pulls more of that through.
Exit the M4, under 10 miles from Gwaun-Cae-Gurwen, by the next junction and park safely, rather than driving on.
Distance matters: every mile carries the AdBlue deeper into the system, and so heading for Swansea, under 15 miles away, makes a much larger job than crossing Gwaun-Cae-Gurwen to the car park by Organised Chaos Youth Circus. Tell us about how far it had come.
There is more to rinse out once your engine has been started, and our engineers do all of it where your car has ended up. Lasting damage is very rare when it's caught early.
What emptying AdBlue from a diesel involves in Gwaun-Cae-Gurwen
Wherever it has stopped around Gwaun-Cae-Gurwen — a filling station, a lay-by, a driveway, a road by Cwmgors Community Centre — the van travels to the car. Three answers decide the work, so before anything else our engineers ask which fluid got in, about the amount, plus if the motor has run.
Then your tank is emptied where the vehicle sits, and so the contaminated fuel and the AdBlue come out together. The system is flushed thoroughly, which counts more with AdBlue than with petrol, since what it leaves behind doesn't rinse out on its own. Next, the fuel filter: flushed, or replaced if it has to be. Then clean diesel, then a test of your vehicle. Engine not run? Then count on roughly half an hour on site for most jobs. The pumps are explosion-proof, safe on a busy forecourt and quiet enough to use outside a house after dark.
Priming the fuel system with fresh diesel comes last. Then our technicians start it and you set off, whether from a parking space by Ammanford or a driveway in Gwaun-Cae-Gurwen. Our engineers check it runs smoothly on new diesel before we leave. Since the job is done in its entirety where your car is, a garage never comes into it. You get a VAT invoice and an engineer report later, which is what insurers want.
