AdBlue in the Diesel Tank in Charlton Kings? Keep It Switched Off

If AdBlue has got into your diesel tank, leave the engine off then leave your ignition off. Water with urea dissolved in it: that's AdBlue. Being water-based, it won't burn and never combines with diesel; trouble only comes when your pump starts drawing it. A drain and a thorough flush, done where the car is around Charlton Kings, is generally all AdBlue in a diesel tank needs — if it is caught before the engine has run. Before you do anything else, phone 0333 366 0103.

AdBlue in your diesel tank around Charlton Kings: the first few minutes

Do:

  • Pull the keys out, so nobody switches your ignition on.
  • Close to moving traffic? Then put the hazards on.
  • The empty bottle or the till receipt shows us the fluid and the amount, so do not bin it away.
  • Give us a postcode starting GL53 8, or whatever street lies nearest, and our van finds you straight — so call wherever you are.

Not to do:

  • No starting the motor — not briefly, not to reposition your car.
  • Switching the key to ignition alone starts your pump going on many diesels. Avoid it.
  • Do not top up with diesel to dilute it. AdBlue does not dilute in diesel; it separates out.
  • Even a short stretch along Hearne Close is too far to drive the vehicle.
  • No emptying it yourself, at all, on the verge.

Ask the attendants to help you move your vehicle away from the pumps if you're on a forecourt around Charlton Kings, whether it's the BP or somewhere else. On your own driveway, do not move it at all.

What AdBlue does in a diesel tank

Meant for your exhaust, AdBlue has no place in your engine. Stored in a dedicated tank, it is injected into the exhaust 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.

Inside a diesel tank it behaves very differently from fuel. It doesn't mix in. It sinks, because it is denser than diesel, and pools down where the intake draws its supply from. Easiest of all: a vehicle that had AdBlue in Ham last night and has not been started since. The AdBlue sits at the base of the tank, undrawn — but it will be first through if the motor runs, ahead of any diesel at all.

Two kinds of harm follow from there. Crystals and corrosion. As the water evaporates, it strands urea that hardens in filters and narrow channels; meanwhile, since it attacks some metals, each part it reaches suffers for as long as it stays inside. If the AdBlue has reached the lines, waiting till morning in Charlton Kings leaves it worse. In that tank alone, time costs nothing. Water lubricates nothing. The injection pump and every injector depend on diesel flowing through them, so the water content harms them by itself.

Draining AdBlue from a diesel tank in Charlton Kings

Why AdBlue in a diesel is commonly more significant than petrol

Put petrol in a diesel at the Esso and you have a fault of thin fuel. It mixes with the diesel, and while it is in that tank it does no harm; the harm comes from running your engine on it.

With AdBlue in a diesel, the fluid itself is simply the wrong one. It does not burn, and so it can't simply be run through. It doesn't stay mixed, and so it cannot be weakened. And crystals and corrosion don't wash out with the next tank of fuel. That's why the flush matters more with AdBlue than with petrol, and why starting your engine "to see" costs more here than nearly anywhere else, whether your car is in Moor End or the middle of Charlton Kings.

With AdBlue, the good news is no separate from petrol. If the engine has not run, the AdBlue is still in that tank, and that tank is the quickest part of a fuel system to clear, wherever across Gloucestershire the vehicle is sitting.

How does AdBlue end up in a diesel tank in Charlton Kings?

Plenty of vehicles put the AdBlue cap beside the diesel one, now and then under one flap, and in dim light the two may look the same. No one intends it. It usually takes place at home, from a bottle bought on the journey home, rather than at the forecourt.

Usually, it happens in one of a few familiar ways. Rushing, outside Charlton Kings Junior School, after a warning light came on during the school run, a parent refills the car. In the evening, a container is tipped in on a drive close to Ledmore Road. Or your car is topped up in the car park at The Merryfellow, in poor light, by a person who has never opened that flap before.

Hired vehicles, brand-new cars, fleet motors, or the second vehicle in a family with both fuels: the least known cars get it most. Leave it switched off: that is the first response to the same mistake, wherever around Charlton Kings or the rest of Gloucestershire you are.

Charlton Kings: started your engine with AdBlue in your diesel tank?

The AdBlue has left the tank, then. It has been sucked through your filter and the fuel lines, and if the engine ran for any time, it has got to the high-pressure pump and your injectors.

Perhaps returning from Grange Tip Open Space, or midway across Charlton Kings, the engine might go rough, smoke, drop pace, light up your dash or cut out. No starting it again to check: pull over once it is safe, then switch everything off. More of that is pulled through with each start.

Exit the M5, under 5 miles from Charlton Kings, by the first junction and stop somewhere safe, rather than carrying on.

How far it went counts. A couple of hundred yards across Charlton Kings to the car park by Stanton Suite is a very different job from a run towards Gloucester, under 10 miles away, with the AdBlue reaching further into the fuel system with each mile. Roughly how far it had come is worth telling us.

Once your engine has been started, the flush takes in more, and all of it is done where the car has stopped. When it is caught soon, long-term damage is very uncommon.

What draining AdBlue from a diesel involves around Charlton Kings

Our engineers come to the car, wherever it has stopped in Charlton Kings: a side street close to Charlton Kings Library and Children's Centre, a drive, a lay-by or a forecourt. The job rests on three answers, which our technicians ask for before all else — what went in, the quantity, and if the engine has turned over.

Right there, the tank is then emptied, and all of the contaminated diesel and the urea come out as one. A careful flush matters far more after AdBlue than after petrol, because what remains will not wash away on its own. A test of your vehicle comes last, after fresh diesel is added and your filter is cleaned or, if needed, replaced. About half an hour on site is typical for most jobs when the engine has not run. Quiet enough to use outside a house at night, and safe on a busy forecourt, the pumps are explosion-proof.

The final step is to prime the system on fresh diesel. Starting the car comes next, and then you head off from where the car is parked, by Cheltenham Spa or on a driveway in Charlton Kings. Before we go, we confirm it's running smoothly with clean diesel in. As the job is done in its entirety where the vehicle is, a garage never comes into it. You get a VAT invoice and an engineer report afterwards, which is what insurers ask for.

AdBlue drains across Charlton Kings and Gloucestershire

Our teams that answer AdBlue call-outs in Charlton Kings also cover the places about it, East End, Ryeworth and Little Herberts among them, and most of Gloucestershire beyond, across the GL postcode area. Ring and ask rather than guess when you're by a county line, or somewhere awkward to explain.

A van that comes to you fits Charlton Kings, a residential suburb: you have no need to take your car to us, since our technicians drain it on the spot, on a driveway, a residential street, a parking area or a forecourt.

AdBlue in a diesel tank in Charlton Kings: the cost of fixing it

Since the callouts vary, a flat price wouldn't be fair. Whether the engine has run, and for how long, comes first in what changes the price. How much AdBlue went in comes next, and then the location of the car, since an open drive is easier for a van to get to safely than a tight spot behind Stocks and Whipping Post.

That's why every call from Charlton Kings starts with the same three questions, asked before giving a figure, not after: what was put in, how much, and if it's run. Those replies shrink a range down to one figure.

The quote is quoted on the call, before a van leaves; payment happens on the day, by card or over the phone, with nothing upfront. Look at your policy while we are on the way: many carry misfuelling cover.
