AdBlue in the Diesel Tank in Leadmill? Keep It Switched Off

If AdBlue has gone into your diesel tank, leave the engine off and keep your ignition off. Water with urea dissolved in it: that's AdBlue. The trouble starts once it is sucked through the pump — it won't ignite, and it will not combine with diesel. Caught before your motor has been run, AdBlue in a diesel tank is normally a drain and a thorough flush, done where your car is around Leadmill. Ring 0333 366 0103 before you do anything else.

Those opening minutes: AdBlue in your diesel tank around Leadmill

Do:

  • So no one can switch the ignition on, pull your keys away.
  • If you're at all close to moving traffic, put the hazard lights on.
  • The empty bottle or the receipt tells us the product and the amount, and so do not throw it away.
  • The van locates you fastest with a postcode starting CH7 1, or simply the name of a street close by, so call from the spot.

Never do these:

  • Shifting your vehicle just a few yards is no reason to fire up the engine.
  • Plenty of diesels power their pump the moment the ignition goes on, so keep the car off.
  • No extra fuel added. The AdBlue will not mix, and so it's pointless.
  • Keep it where it is rather than driving it anywhere, even a short way along Ffordd Argoed.
  • Don't try to drain the vehicle yourself at the roadside.

Get the people behind the counter to help you roll the car away from the pumps if you are at a forecourt in Leadmill, whether it is the Applegreen or elsewhere. At home, the vehicle stays just as it is.

AdBlue in a diesel tank, and what it does there

AdBlue is made for your exhaust, not the motor. Stored in a dedicated tank, it is squirted into the exhaust stream to clean the gases. Nothing in it is supposed to pass through a fuel pump, and nothing in a fuel pump is designed to handle it.

Fuel blends; AdBlue, after poured in, won't. The behaviour is not at all like fuel's. Denser than diesel, it drops and collects below it — the same spot the pickup sucks from. Easiest of all: a vehicle that had AdBlue in Pwll-Glas last night and has not been started since. The AdBlue waits at the foot of the tank, untouched — though it will be the first thing through once the motor runs, ahead of any diesel at all.

Once it's pulled in, the damage takes two forms. Crystals and corrosion. As the water evaporates, it strands urea that hardens in filter elements and narrow passages; and, because it eats at certain metals, each part it touches keeps suffering for as long as it remains inside. By daybreak, a vehicle sitting in Leadmill with AdBlue through its pipework gets worse; if it is just in the tank, it doesn't. The water in it causes harm of its own: your high-pressure pump and the injectors rely on diesel to lubricate them, and water offers them nothing.

Draining AdBlue from a diesel tank in Leadmill

AdBlue in a diesel: why it's commonly worse than petrol

Fill a diesel with petrol in error over at the Tesco, and the issue is thinned fuel. Harm only comes from running on it. Mixed into your diesel and sitting in the tank, it causes none.

With AdBlue in a diesel, the liquid as such is simply the wrong one. Not burning, it can't just be run through. It does not stay mixed, so it can't be thinned. 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 motor "to see" costs more here than nearly anywhere else, whether the vehicle is in Glanyrafon or the middle of Leadmill.

With AdBlue, the good news is no distinct from petrol. Emptying a tank is the easiest job on a fuel system, and with no running, the AdBlue remains in it — wherever across Flintshire your vehicle sits.

AdBlue in a diesel tank in Leadmill: how it ends up there

After dark, two caps side by side — the AdBlue one and the diesel one, occasionally under a single flap — may look the same. No one means it; plenty of designs invite it. Usually it's not the forecourt: a driver picks up a bottle heading home and tips it in outside the house.

It tends to take place in a few familiar ways. Rushing, outside the local primary school, after a warning lamp came on during the school run, a parent tops up your car. A driver tips the container in outside their house, right off Mold Road, as the day ends. Or someone new to that flap tops up the vehicle after dark, parked in the car park by Glasfryn.

It crops up the most in a hire car, a new motor, a fleet car, or the spare vehicle in a home with one of each fuel types — the vehicles drivers know least. Anywhere around Flintshire, Leadmill included, the mistake does not change, and nor does the first response: leave it switched off.

Already started the motor with AdBlue in your diesel tank around Leadmill?

Then that tank is no longer where the AdBlue is. Via your filter, along the pipework, and — with any running — into the high-pressure pump and each injector: that's where it has gone.

You may see your motor running roughly, smoking, losing power, showing warning lights or cutting out, possibly on the way back from Bailey Hill or halfway across Leadmill. Stop as soon as it is safe, switch off, and do not restart the car to check. More of that is pulled through with each start.

On the M56, under 10 miles from Leadmill, the next junction is where to leave, and somewhere sensible is where to stop — not carrying on.

Mileage matters: each mile carries the AdBlue deeper into the system, and so driving towards Chester, under 15 miles away, gives a far bigger job than crossing Leadmill to the car park by Church of Saint David. Approximately how far had it come? Tell us.

There's more to clean out once the motor has been started, and our engineers do all of it where the vehicle has ended up. Permanent damage is very rare if it is caught soon.

Leadmill: how AdBlue is emptied from a diesel

Wherever it has stopped around Leadmill — a forecourt, a lay-by, a driveway, a street beside The Law Courts — the van comes to your car. Before anything else we ask what went in, about how much, and if the engine has run, because those answers determine this work.

The polluted diesel and the urea leave together after your tank is drained, right there. With AdBlue, far more than with petrol, flushing counts: the whole system is flushed all the way through because what remains will not wash away unaided. A test of the vehicle follows last, after clean diesel is added and the fuel filter is flushed or, if needed, replaced. About half an hour once we arrive is usual for most jobs when your engine hasn't run. Explosion-proof pumps mean a live forecourt sensible to work on, and they're quiet enough to spare the street at night.

Clean diesel goes in to prime your system, and that is the last step. Then our engineers fire it up and you drive off, whether from a parking space outside Buckley or a drive around Leadmill. Before we go, our engineers confirm it's running correctly with clean diesel in. No workshop is needed at any stage, with the entire job done then and there. At the end, there is the paperwork for your insurer: a VAT invoice and a report from the engineer.

Leadmill and Flintshire: AdBlue drains across the area

AdBlue call-outs around Leadmill are passed to teams that cover the towns near it — Ponterwyl, Pentre as well as Mold — and much of Flintshire further out, throughout CH postcodes. Close to a boundary, or anywhere tricky to explain? Asking beats guessing, so ring.

No towing is needed. In Leadmill, a residential suburb, a van that comes to you works: the vehicle is emptied on the spot, be it in a drive, a side street, a parking area or a filling station.

AdBlue in a diesel tank around Leadmill: the cost of fixing it

Since the callouts differ, a single price would not be fair. What moves the price is, first of all, whether the engine has been running and for how long; then how much AdBlue went in; and then where the vehicle is and whether a technician can reach it safely, which is simpler on an open driveway than in a tight gap behind Clwyd Theatr.

That is why each call from Leadmill starts with the same three queries, asked before giving a figure, not after: what got in, how much, and whether it has run. Their replies shrink a range right down to one figure.

The price is given during the call, before anyone leaves; payment comes on the day, by card or over the phone, and nothing upfront. As our engineer is travelling, dig out your policy: many cover misfuelling.

Leadmill: still beside the car?

In that case, do nothing — that's the most helpful move there is. Keys out; motor and ignition off. Ring 0333 366 0103 and tell us it's AdBlue, roughly how much, and whether it's run. Petrol in Diesel takes it from there, in Leadmill or anywhere across Flintshire.
