Don't Start It: AdBlue in a Diesel Tank in Round Hill

With AdBlue in the diesel tank, your ignition remains off and so does the engine. Urea dissolved in water is all AdBlue is. Not like fuel, it neither burns nor mixes, and no harm starts until your engine sucks it round. Caught before your motor has been run, AdBlue in a diesel tank is normally a drain and a thorough flush, done where the car is around Round Hill. Before you do anything else, phone 0333 366 0103.

Those opening minutes: AdBlue in your diesel tank in Round Hill

To do:

  • So no one can switch your ignition on, pull your keys out.
  • Hazards on, if moving traffic is at all close.
  • The empty bottle or the till receipt shows us the fluid and the quantity, and so do not bin it away.
  • Tell us a postcode starting BN1 4, or whatever street lies nearest, and the van finds you straight — so call wherever you are.

Never:

  • Not even briefly, and not to roll your car: the motor stays off.
  • Do not switch your ignition on. On plenty of diesels that alone runs the fuel pump.
  • AdBlue does not dilute in diesel — it separates out — so adding extra diesel will not thin it.
  • Keep the car where it is instead of driving it anywhere, even a short distance down Princes Crescent.
  • Emptying your tank on your own by the road isn't one to try.

Rolling your vehicle off the pumps is a job for attendants to help with, whichever Round Hill forecourt you're on, the BP included. Stopped on your own drive? Then it remains just as it is.

AdBlue in a diesel tank, and what it does there

Not the motor but your exhaust is where AdBlue is meant to go. It goes into its own tank and is sprayed into your exhaust gas to clean it. Not one side suits the other: urea doesn't belong in an injection pump, and an injection pump cannot take urea.

Inside a diesel tank it acts really differently from fuel. It doesn't mix in. It drops, because it's heavier than diesel, and pools down where the pickup draws its fuel from. The first thing the fuel system pulls through, once it runs, is the AdBlue. So a motor that had AdBlue poured in on a drive in Brighton and Hove last night, and hasn't been started since, is still the simple case: the AdBlue is lying at the bottom of your tank, and nothing has sucked it in.

It causes two kinds of harm from there. What remains once the water goes is urea, which turns into crystals: they settle in tiny passages and block filters. Worse, it attacks some metals in a fuel system, and carries on till it is cleared out. Overnight, a vehicle sitting in Round Hill with AdBlue through its pipework gets worse; if it's only in your tank, nothing changes. The water in it causes harm of its own: the high-pressure pump and the fuel injectors rely on diesel to lubricate them, and water offers them nothing.

Draining AdBlue from a diesel tank in Round Hill

Petrol or AdBlue in a diesel: why AdBlue is commonly worse

Top up a diesel with petrol by mistake over at the Shell, and this issue is diluted fuel. No harm comes while it stays unused, mixed into your diesel — only when your engine runs on it.

With AdBlue in a diesel, the liquid itself is simply the wrong one. It does not burn, so it can't simply be run through. Whether the vehicle sits in Moulsecoomb or the heart of Round Hill, firing it up "to see" does more harm with AdBlue than almost any other mistake, and the flush counts for more. The reasons: it won't stay blended, so diluting it is impossible; and crystals and corrosion survive the following tankful.

The same good news holds as with petrol. Emptying a tank is the simplest part on a fuel system, and without start-up, the AdBlue remains in there — wherever around East Sussex your car sits.

AdBlue in a diesel tank around Round Hill: how it ends up there

After dark, two caps together — the AdBlue one and the diesel one, occasionally behind one flap — can appear the same. No one intends it; plenty of designs invite it. It mostly occurs at home, from a container bought on the journey home, not at the filling station.

It tends to occur in a couple of familiar ways. A warning light comes on during the school run, and the top-up happens in a hurry outside Downs Infant School. Close to Round Hill Street, a driver pours a bottle in at home after work. Or the car is topped up in the car park outside The Roundhill, in poor light, by somebody who has never opened that flap before.

It crops up the most in a rental, a brand-new motor, a fleet car, or the other motor in a family with one of each fuel types — the vehicles people use the least. Wherever you are in Round Hill or the remainder of East Sussex, it's the same error and the same first answer: leave the vehicle off.

Already started the motor with AdBlue in the diesel tank in Round Hill?

Then the AdBlue has left your tank. Via the filter, along the lines, and — given any running time — into the high-pressure pump and every injector: that is where it has gone.

Rough running, smoke from the exhaust, dropping power, dashboard warnings or stalling: each might appear, perhaps part way across Round Hill or coming back from Park Crescent Park. Stop when safe. Turn off. Leave the vehicle off rather than testing it again. Each start pulls more of it through.

Leave the M23, under 25 miles from Round Hill, at the next junction and stop somewhere safe, rather than carrying on.

Hopping across Round Hill to the car park by Florence Road Baptist Church is one thing; driving for Brighton and Hove, under a mile away, is something else, because each mile pushes the AdBlue deeper in. So distance counts. Roughly how far had it come? Tell us.

Wherever your car came to a stop is where all of it gets done, even with more to flush after the engine has been run. Caught quickly, it very rarely leaves permanent damage.

What emptying AdBlue from a diesel involves around Round Hill

A street beside Florence Road Market, a driveway, a lay-by or a filling station: anywhere your vehicle has stopped around Round Hill, our technicians travel to it. Which fluid was put in, about the quantity, and whether your motor has been run: our engineers check first, because those shape the work.

The polluted diesel and the urea leave as one when your tank is drained, right there. With AdBlue, far more than with petrol, flushing counts: the fuel system is cleaned all the way through since what remains will not flush out by itself. A test of the car follows last, once fresh diesel goes in and your filter is cleaned or, if necessary, replaced. Engine not run? Then expect roughly half an hour on site for most jobs. Low-noise enough for use outside a house at night, and fine on a working forecourt, our pumps are explosion-proof.

Clean diesel goes in to bleed the system, and that's the last step. Firing it up comes next, and then you head off from where your car is parked, at London Road (Brighton) or on a driveway in Round Hill. Before we go, our engineers confirm it's running correctly with fresh diesel in. Because the job is done in its entirety where the vehicle is, a garage never comes into it. The insurer will want an engineer's report and your VAT invoice — both yours once the job is done.

Round Hill sits on a slight elevation of around 74 metres, overlooking the coastal city and its surroundings.

Round Hill is a densely populated area, with a population of approximately 20,321 people.

AdBlue drains in Round Hill and across East Sussex

Hollingdean, Preston and Brighton are among the places near Round Hill that the same vans reach, along with much of East Sussex further out, throughout the BN postcode area. Close to a boundary, or anywhere tricky to pin down? Asking is better than guessing, and so phone.

Round Hill is a residential suburb, and a call-out drain suits it: whether the car is on a home drive, a residential street, a car park or a forecourt, our technicians drain it where it stands, and so it never needs to be moved to us.

What AdBlue in a diesel tank costs to put right in Round Hill

Each job differs, and so not one fixed price is fair. Three things change the cost: whether the motor has run and for how long, how much AdBlue went in, and where your car is. That last one turns on whether our van can reach it safely, and an open driveway is simpler than a tight spot behind Calvary Evangelical Church.

Ahead of a quote, never afterwards, every enquiry from Round Hill opens with the same three questions: the liquid, the amount, plus if it ran. Once they are known, a range turns into one firm number.

Priced by phone before the engineer heads out, it is settled on the day — card or phone, no deposit. As the van is on the way, dig out your insurance: plenty cover misfuelling.
