AdBlue in the Diesel Tank in Llandudno Junction? Keep It Switched Off
If AdBlue has gone into the diesel tank, leave your engine off and leave the ignition off. Water with urea dissolved in it: that is AdBlue. As it is water-based, it will not burn and never combines with diesel; damage only starts once your pump starts drawing it. A drain and a thorough flush, done where the car is in Llandudno Junction, is normally what AdBlue in a diesel tank needs — if it is caught before the motor has run. Phone 0333 366 0103 before you do anything else.
Those opening minutes: AdBlue in the diesel tank around Llandudno Junction
To do:
- So no one can switch the ignition on, take the keys out.
- Close to moving traffic? Then put the hazards on.
- Hold on to your receipt or the empty bottle, and so you can tell us what got in and about how much.
- Tell us a postcode starting LL31 9, or whichever street is nearest, and the van finds you directly — so call wherever you stand.
Not to do:
- No starting the engine — not briefly, not to shift the vehicle.
- The ignition remains off: on many diesels, turning it on is enough to run your fuel pump.
- AdBlue doesn't dilute in diesel — it separates out — so adding more diesel will not thin it.
- Even a short stretch up Marl Avenue is too far to drive it.
- Do not try to drain the car yourself by the kerbside.
The staff working at any Llandudno Junction filling station — the Tesco included — will normally help rolling it aside if you ask. At your own drive, do not move it at all.
What does AdBlue do in a diesel tank?
Not your engine but your exhaust is where AdBlue is meant to go. Its own tank holds it, and from there it's fed into your exhaust, where it cleans the gas. Nothing in it is meant to pass through a fuel pump, and nothing in a fuel pump is made to handle it.
Inside a diesel tank it acts really differently from fuel. It does not mix in. Denser than diesel, it sinks and pools below it — the very spot the intake sucks from. Simplest of all: one that had AdBlue in Conwy overnight and has not been started since. The AdBlue sits at the base of that tank, untouched — though it would be the first thing through if your engine runs, before any diesel at all.
It causes two kinds of damage from there. As its water goes, the urea left behind crystallises, and the crystals block filters and settle in fine passages. And it is corrosive to some of the metals a fuel system is made from, and so it keeps running on the components it gets to for as long as it remains there. By daybreak, a vehicle parked around Llandudno Junction with AdBlue through its pipework grows worse; if it's only in the tank, it doesn't. The water in it causes damage of its own: the high-pressure pump and the injectors rely on diesel to lubricate them, and water gives them nothing.
Petrol or AdBlue in a diesel: why AdBlue is often worse
Fill a diesel with petrol in error over at the Shell, and this issue is diluted fuel. Mixed into your diesel and sitting still, it is harmless for now; using your motor does the harm.
AdBlue in a diesel is an issue of the wrong substance altogether. Not burning, it can't just be run through. Whether the vehicle is in Llanrhos or the centre of Llandudno Junction, turning it over "to see" costs more in this case than almost any other error, and the flush counts more. The reasons: it will not stay blended, and so watering it down is impossible; and crystals and corrosion outlast the following tankful.
As with petrol, there's good news. Anywhere in Conwy your vehicle has stopped, an unstarted motor means the AdBlue still in the reservoir: the simplest part of a fuel system to empty.
How AdBlue ends up in a diesel tank around Llandudno Junction
It is not deliberate. Plenty of vehicles have the AdBlue cap beside the diesel inlet, now and then under one flap, and muddling them up is simple after dark. Mostly it's not the forecourt: a driver picks up a bottle driving home and pours it in outside the house.
It tends to occur in a couple of familiar ways. A warning light comes on during the school run, and the top-up takes place in a hurry outside the local primary school. Someone pours the container in at home, just off Marl Crescent, as the day ends. One more pattern: darkness, a pub car park by Old Station Hotel, and a driver using that flap the first time.
It takes place most in the cars drivers know least: a hire car, a new car, a company car, or the second car of a household with one diesel and one petrol. An identical mistake, same first response — keep it switched off — wherever you happen to be around Llandudno Junction or the rest of Conwy.
Llandudno Junction: started the motor with AdBlue in your diesel tank?
Then the AdBlue has left that tank. With any running, it goes on to the injection pump and each injector, having passed through your filter and pipework.
Maybe coming back from Parc Cae Derw, or part way across Llandudno Junction, the engine may go lumpy, smoke, lose pace, flash the dash or cut out. No starting it again to check: stop when it is safe, then switch it off. Each start pulls more of it through.
Exit the Moreton Spur, under 50 miles from Llandudno Junction, by the next junction and park somewhere safe, not carrying on.
Each mile carries the AdBlue deeper in. That is why crossing Llandudno Junction to park near Caersalem and a drive of under 15 miles for Bangor are such distinct jobs. Let us know roughly how far it had come.
Once the motor has run, the flush includes more, and all of it is done where your car has come to a stop. Spotted soon, it very rarely leaves long-term damage.
Llandudno Junction: how AdBlue is drained from a diesel
We come to your car, wherever it has stopped around Llandudno Junction: a side street near Capel Coffa, a drive, a lay-by or a forecourt. The work rests on three replies, which our technicians ask for before all else — what got in, the amount, and if your motor has turned over.
Then your tank is emptied where your car stands, and so the contaminated fuel and the AdBlue come out together. With AdBlue, far more than with petrol, flushing counts: the whole system is flushed all the way through since residue won't flush out unaided. Your filter is cleaned, or replaced where it needs to be; clean diesel goes in; and the car is tested. The majority of these jobs are a half-hour visit once we get there, if the engine has not run. Our equipment is explosion-proof, and so a live filling station is no fault, and it's quiet enough for a residential street late at night.
Priming the fuel system with fresh diesel comes at the end. You drive off as soon as our engineers have started the car, and it makes no difference whether the vehicle is on a driveway in Llandudno Junction or in a space by the nearest station. Our technicians make sure it runs correctly on fresh diesel before leaving. The whole job is done where the vehicle is, so it never has to go to a garage. Insurers ask for a VAT invoice and an engineer report, and both come at the end.
