Don't Start It: AdBlue in a Diesel Tank in Upminster

With AdBlue in the diesel tank, the ignition remains off and so does the motor. Urea mixed in water is all AdBlue is. The trouble begins once it's sucked through the lines — it won't burn, and it will not combine with diesel. In Upminster, AdBlue in a diesel tank caught before your motor runs normally means a drain and a thorough flush, just where your car is. Nothing comes before calling 0333 366 0103.

What to do right now, Upminster: AdBlue in the diesel tank

Things to do:

  • So nobody can switch the ignition on, pull your keys away.
  • Hazards on, if moving traffic is anywhere near.
  • Hold on to the till receipt or the empty bottle, so you can tell us what went in and roughly how much.
  • The van finds you fastest with a postcode starting RM14 2, or simply the name of a street nearby, so call from the car.

Do not:

  • Shifting your vehicle even a short way is no reason to fire up the motor.
  • Plenty of diesels run their pump the instant your ignition goes on, so leave the car off.
  • Adding extra diesel does not work: AdBlue separates out rather than thinning.
  • Any driving at all is best avoided, even a short stretch down Station Road.
  • By the road, don't try emptying it yourself.

Rolling your car away from the island is a job for attendants to help with, wherever Upminster forecourt you are on, the Shell included. Stopped on your own drive? Then it stays exactly as it is.

AdBlue in a diesel tank, and what it does there

AdBlue is made for the exhaust, not the motor. Kept in a separate tank, it is injected into the exhaust to clean the fumes. A fuel pump isn't made to cope with it, and AdBlue was never supposed to go through one.

Inside a diesel tank it acts really differently from fuel. It doesn't mix in. It sinks, since it is denser than diesel, and pools down where the intake takes its fuel from. Once your system runs, the AdBlue is top of the list to be pulled through. Before then it waits beneath your diesel, which is why a car filled in Hornchurch yesterday and never switched on remains the straightforward one, as long as nobody turns the key.

It does two kinds of harm 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 labouring on the parts it hits for as long as it stays there. Overnight, a car sitting around Upminster with AdBlue in its lines gets worse; if it is only in that tank, it doesn't. The water in it does harm of its own: your high-pressure pump and the fuel injectors depend on diesel to lubricate them, and water gives them nothing.

Draining AdBlue from a diesel tank in Upminster

Why AdBlue in a diesel is regularly more serious than petrol

A fault of thinned fuel is what you get after filling a diesel with petrol from the Texaco. Damage only comes from driving on it. Mixed into the diesel and sitting in that tank, it does nothing.

AdBlue in a diesel is another matter: not thin fuel, yet no fuel at all. Because it doesn't burn, running it through is not an option. Nor can it be watered down, because it separates back out — and the next fill will not rinse away crystals or corrosion. So the flush counts for more here, and turning the key "to see", in the heart of Upminster or out in Emerson Park, does more harm than nearly any other error.

As with petrol, there's good news. If your engine hasn't run, the AdBlue is still in your tank, and that tank is the easiest part of a fuel system to clear, wherever across Greater London the car is standing.

Upminster: how AdBlue ends up in a diesel tank

It's not deliberate. Plenty of cars keep the AdBlue cap alongside the diesel one, now and then behind one flap, and mixing them up is simple in poor light. Mostly it is not the forecourt: a driver buys a container driving home and pours it in at home.

The ways it occurs are few and familiar. Midway through the drop-off, the dashboard flags it up, and outside St Joseph's Catholic Primary School the refill is hurried. A driver tips the bottle in at home, just off Corbets Tey Road, as the day ends. Otherwise, in dim light outside BrewDog, the vehicle is topped up by someone using that flap the first time.

Rented cars, new vehicles, fleet motors, or the spare vehicle in a home with both fuels: the least familiar cars see it most. Wherever in Greater London, Upminster included, the mistake does not change, and nor does the first step: leave it off.

Upminster: started your engine with AdBlue in the diesel tank?

Then the tank is no longer where the AdBlue is. Through your filter, through the pipework, and — given any running time — into the high-pressure pump and each injector: that's how far it travels.

Watch for lumpy running, smoke, falling power, lights on the dash, or a stall — coming back from Upminster Park, say, or midway across Upminster. When safe, pull over then turn it off — without turning it on again to test. Each start pulls more of that through.

On the M25, under 3 miles from Upminster, the next junction is where to exit, and somewhere safe is where to park — not carrying on.

Every mile pushes the AdBlue deeper in. That's why crossing Upminster to park near Upminster War Memorial and a drive of under 25 miles towards London are such distinct jobs. About how far it had come is worth telling us.

Wherever the car came to a stop is where all of it gets done, even with more to clean out after your engine has been started. Very rarely does it leave long-term damage if it's noticed soon.

What emptying AdBlue from a diesel involves around Upminster

The car remains where it is, whether that is a road near Church of Saint Laurence, a driveway, a lay-by or a filling station in Upminster, and the van travels to it. Three answers decide the work, so first we ask what was put in, about the amount, and whether the engine has run.

Next, emptying your tank right there removes the polluted diesel and the AdBlue together. A careful flush matters far more with AdBlue than with petrol, since residue won't wash out on its own. Clean diesel goes in once your filter is flushed — or replaced, when it needs to be — and after that the car is tested. The majority of these jobs are a half-hour visit once our engineers turn up, if the engine has not run. Low-noise enough for use outside a house at night, and safe on a busy forecourt, our pumps are explosion-proof.

The final step is to bleed the fuel system on clean diesel. Starting the car comes next, and then you drive off from where the car is parked, outside the nearest station or on a drive in Upminster. It's checked on clean diesel to make sure it runs correctly before our technicians leave. Our engineers do it all wherever the car has stopped, and it never needs to be taken to a garage. Afterwards, you are given the paperwork for the insurer: a VAT invoice plus a written report from the engineer.

About Upminster

Upminster is a locality in the London Borough of Havering, situated on the north bank of the River Thames at an elevation of around 24 metres. Upminster lies on the outskirts of Greater London, approximately 16.5 miles from central London, and is characterized by its semi-detached housing stock. Upminster is close to nearby places such as Upminster Bridge, Corbets Tey, and Cranham, and has a population of around 3605 residents.

Upminster and Greater London: AdBlue drains across the area

Our vans that answer AdBlue call-outs in Upminster also cover the spots about it, Upminster Bridge, Corbets Tey and Cranham among them, and most of Greater London beyond, across the RM postcode area. Near a boundary, or somewhere tricky to pin down? Checking beats guessing, and so phone.

No towing is needed. In Upminster, a small village, a mobile service fits: the car is drained where it stands, be it in a drive, a residential street, a parking area or a filling station.

What does AdBlue in a diesel tank cost to sort out in Upminster?

Since the callouts differ, a flat price would not be honest. The price changes first with how long, if at all, the motor has been running, and next with the amount of AdBlue that got in. After that it rests on where your car is and whether a technician can get to it safely, which is simpler on an open driveway than in a tight space behind Upminster Library.

For that reason, each enquiry from Upminster begins by asking the same trio — which fluid got in, how much, whether it ran — before any figure. With them, the range shrinks to a single fixed number.

Quoted on the call before the van sets out, the job is paid for that day — card or phone, no deposit. Plenty of insurance policies include misfuelling cover, and so it is worth checking yours whilst we're on the way.
