Wellington Place: AdBlue in the Diesel Tank? Leave It Off

AdBlue in your diesel tank? Then keep the engine off — and the ignition too. In plain terms, AdBlue is just urea in water. It doesn't burn, it doesn't mix with diesel, and the damage it does begins when your fuel system draws it in. A drain and a thorough flush, done where your car is around Wellington Place, is generally what AdBlue in a diesel tank needs — if it's caught before your engine has been run. Ring 0333 366 0103 before you do anything else.

Wellington Place, AdBlue in the diesel tank: what to do right away

To do:

  • Take the keys out, and so nobody switches the ignition on.
  • Put the hazards on if you are at all near moving traffic.
  • The empty bottle or the till receipt shows us the fluid and the quantity, and so don't throw it out.
  • Ring just where you are. Quote a WV13 1 postcode or the closest street sign, and nobody has to search for you.

Things not to do:

  • Shifting your car just a short way is no reason to fire up the engine.
  • Plenty of diesels power their fuel pump the moment the ignition goes on, and so leave the vehicle off.
  • AdBlue does not mix in diesel — it separates out — so adding more diesel won't thin it.
  • Never drive it anywhere, not even a short way along Webster Road.
  • Don't try to drain it yourself by the kerbside.

At a forecourt in Wellington Place, whether it's the the nearest petrol station or another one, ask the staff to help you roll the car away from the petrol pump. At your own drive, do not touch it at all.

What does AdBlue do in a diesel tank?

Not the engine but your exhaust is where AdBlue is meant to go. From a dedicated reservoir it is fed straight to your exhaust, treating what the engine emits. Nothing in it is meant to pass through a fuel pump, and nothing in a fuel pump is built to handle it.

Poured in with your diesel, it stays apart rather than mixing — entirely different from fuel. The pickup sucks fuel from the lowest part of your tank, and that's just where AdBlue ends up: as it is denser than diesel, it sinks. Once the pump runs, the AdBlue is first to be pulled through. Before then it waits beneath the diesel, which is why a vehicle filled in Ashmore Lake last night and not switched on remains the straightforward case, as long as nobody turns your key.

It causes two kinds of damage from there. Crystals and corrosion. As the water evaporates, it leaves urea that hardens in filter elements and tiny channels; and, since it attacks some metals, each part it reaches suffers for as long as it remains in there. Pipes holding AdBlue mean harm overnight for a vehicle sitting around Wellington Place. Only inside the tank, it stays the same. Diesel lubricates the high-pressure pump and each injector as it flows; water offers none of that, and that is a second form of damage.

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

Petrol pumped into a diesel on Morrisons's forecourt leaves your fuel thin — that is the whole issue. It mixes with your diesel, and while it is inside the tank it does no damage; the harm comes from running the motor on it.

With AdBlue in a diesel, the liquid as such is plainly the wrong one. It can't simply be run through, since it does not burn. Deposits and corrosion stay after the following tankful, and AdBlue splits back out of your diesel, and so watering it won't work. Hence the flush matters more, and turning the key "to see" does more harm here than nearly any other slip — in Willenhall or the heart of Wellington Place alike.

The good news is the same as with petrol. Emptying a tank is the simplest part on any fuel system, and with no running, the AdBlue stays in there — anywhere around West Midlands the car sits.

Wellington Place: how AdBlue ends up in a diesel tank

It is not on purpose. Plenty of vehicles have the AdBlue cap alongside the diesel inlet, occasionally under one flap, and muddling them up is easy after dark. It usually takes place outside the house, from a bottle grabbed on the journey home, not at the forecourt.

Usually, it occurs in one of a couple of familiar ways. Midway through the drop-off, the dashboard flags it up, and outside Fibbersley Park Academy the refill is rushed. Someone tips the bottle in at home, right off Wednesfield Road, as the day ends. Else, in dim light outside The Falcon Inn, your car is topped up by someone using that flap for the first time.

It takes place most in the motors 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. Keep it switched off: that's the first response to the same slip, wherever around Wellington Place or the rest of West Midlands you are.

Started your engine with AdBlue in the diesel tank around Wellington Place?

Then your tank is no longer where the AdBlue is. It's been drawn through the fuel filter and your lines, and if the engine ran for any time, it has reached your high-pressure pump and the injectors.

You may see the motor running roughly, smoking, losing power, showing warning lights or cutting out, possibly on the way back from Black Country Millennium Forest or halfway across Wellington Place. Pull over when safe. Turn off. Keep the vehicle off instead of restarting it to check. Every start pulls more of that through.

Exit the M6, under 3 miles from Wellington Place, by the next junction and stop somewhere safe, rather than driving on.

Every mile carries the AdBlue further in. That is why crossing Wellington Place to park near Willenhall War Memorial and a drive of under 5 miles for Wolverhampton are such different jobs. Let us know about how far it had come.

Once your engine has been started, the flush covers more, and all of it is done where your car has come to a stop. Very rarely does it leave lasting damage if it's caught soon.

Draining AdBlue in a diesel around Wellington Place: what it takes

Anywhere it has come to rest in Wellington Place — a forecourt, a layby, a drive, a street beside The Salvation Army - Willenhall — our van travels to the car. Which fluid went in, about how much, and whether your motor has turned over: our technicians check before all else, because those shape the work.

Next, draining your tank on the spot takes out the contaminated diesel along with the AdBlue in one go. What remains from AdBlue won't wash out by itself, and so the fuel system gets a full flush, which counts much more here than with petrol. The filter is cleaned, or replaced where it needs to be; clean diesel goes in; and the car is tested. Engine not run? In that case count on roughly half an hour on site for most jobs. Explosion-proof pumps make a live forecourt safe to work on, and they're quiet enough not to disturb the neighbours at night.

The last step is to prime the fuel system on fresh diesel. Then our engineers start it and you head off, whether from a parking space at Willenhall or a drive in Wellington Place. It is checked on new diesel to confirm it runs correctly before we leave. Our engineers do it all wherever the vehicle has ended up, and it never has to be taken to a workshop. You receive a VAT invoice and an engineer report later on, which is what insurers ask for.

What AdBlue in a diesel tank costs to put right around Wellington Place

There's no honest single quote, because the jobs are not the same. Three things change the cost: whether your engine has been running and for how long, how much AdBlue went in, and where your car is. That last one turns on whether a technician can get to it safely, and an open driveway is easier than a tight space behind St Anne.

That's why every call from Wellington Place starts with the same three questions, asked before giving a figure, not after: what was put in, how much, and if it has run. Once they are answered, a range becomes a single firm number.

Priced by phone before the van sets out, it is paid for that day — card or phone, no deposit. Many insurance policies include misfuelling cover, so it's worth checking yours while we are on the way.
