# AdBlue in a Diesel Tank in South Barrwood? Don't Start It

Motor off, ignition off: that is where you begin if AdBlue has gone into your diesel tank.

Urea dissolved in water is all AdBlue is.

Not like fuel, it neither burns nor blends, and no harm happens till your motor sucks it through.

If your engine hasn't run yet, AdBlue in a diesel tank is usually drained and carefully rinsed where the car stands in South Barrwood.

Before anything, ring us on 0333 366 0103.

## Those opening minutes: AdBlue in the diesel tank around South Barrwood

Do these:

- Take your keys out, and so nobody switches your ignition on.

- Near moving traffic? Then put the hazard lights on.

- The empty bottle or the receipt tells us the product and the amount, and so do not bin it out.

- Ring just where you are. Say a G65 0 postcode or the closest street name, and no one has to search for you.

Not to do:

- Don't start your engine, even for a moment to shift the vehicle.

- Many diesels power their pump the moment the ignition goes on, and so leave it off.

- No extra fuel added. The AdBlue won't mix, so it is pointless.

- Any driving at all is to be avoided, including a short stretch down Barrpath.

- By the road, do not attempt draining it yourself.

Rolling your car away from the pumps is a job for staff to help with, whichever South Barrwood forecourt you are on, the Shell or any other.

At your own drive, do not move it at all.

## What does AdBlue do in a diesel tank?

Made for your exhaust, AdBlue has no business in your engine.

It goes into its own tank and is sprayed into the exhaust gas to clean it.

A fuel pump is not designed to take it, and AdBlue was never intended to travel through one.

Inside a diesel tank it acts really differently from fuel. It does not mix in.

It is heavier than diesel, so it sinks and collects at the bottom of the tank, which is where the pickup draws fuel from.

The first thing the fuel system pulls through, after it runs, is the AdBlue. So a motor that had AdBlue poured in on a drive in Kilsyth last night, and has not been started since, is still the straightforward case: the AdBlue is lying at the bottom of the tank, and nothing has drawn it in.

Two kinds of harm come from there.

Crystals and corrosion. As the water evaporates, it leaves urea that hardens in filter elements and tiny channels; meanwhile, because it attacks certain metals, every part it reaches keeps suffering for as long as it stays inside.

A vehicle left sitting in South Barrwood with AdBlue already in its lines is worse by the morning; one with AdBlue only in its tank is not.

The water in it causes damage of its own: the high-pressure fuel pump and the fuel injectors depend on diesel to lubricate them, and water offers them nothing.

## Petrol or AdBlue in a diesel: why AdBlue is regularly worse

Petrol put into a diesel on Tesco's forecourt makes the fuel watery — that is the whole fault.

Harm just comes from running on it. Mixed into the diesel and sitting in that tank, it causes nothing.

AdBlue in a diesel is an issue of the wrong substance altogether.

It can't simply be run through, because it does not burn.

It doesn't stay mixed, and so it cannot be diluted. And crystals and corrosion do not wash out with the next tank of fuel. That is why the flush matters more with AdBlue than with petrol, and why starting the engine "to see" costs more here than almost anywhere else, whether the car is in Balmalloch or the middle of South Barrwood.

With AdBlue, the good news is no separate from petrol.

Anywhere in North Lanarkshire the car has stopped, an unrun motor means the AdBlue yet inside the tank: the simplest part of a fuel system to empty.

## How AdBlue ends up in a diesel tank around South Barrwood

Plenty of cars put the AdBlue filler alongside the diesel cap, now and then behind a single flap, and in dim light the two can appear the same. No one means it.

Mostly it is not the filling station: someone picks up a bottle heading home and pours it in at home.

Usually, it occurs in one of a few familiar ways.

A warning light comes on during the school run, and the top-up takes place in a hurry outside the local primary school.

After work, a bottle is tipped in on a drive near South Barrwood Road.

Another pattern: dim light, the car park by the pub in the village, and someone opening that flap the first time.

The least known cars see it most — hire cars, brand-new ones, fleet ones, and the spare vehicle of a family with one of each fuels.

Wherever in North Lanarkshire, South Barrwood as well, the mistake does not change, and nor does the first step: leave it off.

## South Barrwood: started the engine with AdBlue in the diesel tank?

Then the AdBlue has left the tank.

Via the fuel filter, along the lines, and — given any running time — on to the high-pressure pump and each injector: that is how far it travels.

Watch for lumpy running, smoke, lost power, lights on your dash, or a cut-out — returning from Craigmarloch Wood, say, or part way across South Barrwood.

Pull over when safe. Turn off. Keep it off rather than restarting it to check.

More of it is pulled through with each start.

Exit the M80, under 3 miles from South Barrwood, at the first junction and stop somewhere safe, rather than carrying on.

How far it went counts. A couple of hundred yards across South Barrwood to the car park by St Patrick's Catholic Church is a very different job from a run towards Glasgow, under 15 miles away, with the AdBlue reaching further into the fuel system with each mile.

Let us know about how far it had come.

There's more to clean out once the engine has been started, and our engineers do all of it where your car has ended up.

If it is spotted quickly, permanent damage is very rare.

## Clearing AdBlue in a diesel around South Barrwood: what it takes

The car remains where it is, whether that's a street near Kilsyth Community Church, a drive, a layby or a filling station around South Barrwood, and our van travels to it.

Three answers shape the job, so first we ask which fluid was put in, roughly what quantity, plus whether the engine has turned over.

Then that tank is emptied where the car waits, so the polluted fuel and the AdBlue come out together.

Residue from AdBlue will not flush away by itself, and so the whole system gets a careful flush, which matters much more with urea than for petrol.

The fuel filter is cleaned, or replaced where it needs to be; clean diesel goes in; and the car is tested.

About half an hour on site is usual for most jobs when the motor hasn't run.

The pumps are explosion-proof, safe on a busy forecourt and quiet enough to use outside a house at night.

Clean diesel goes in to prime the fuel system, and that is the final step.

At that point we start the car and you drive off, whether from a parking bay outside Croy or a driveway around South Barrwood.

It's checked on fresh diesel to make sure it runs correctly before we head off.

No workshop is needed at any point, with the entire job done on the spot.

The insurer will want an engineer's report and the VAT invoice — both yours afterwards.

South Barrwood is a residential suburb, and a call-out drain suits it: whether the vehicle is on a home drive, a residential street, a car park or a forecourt, our engineers drain it where it sits, so it never needs to be moved to us.

## South Barrwood: what AdBlue in a diesel tank costs to fix

Not one single figure could be honest, because every job differs.

What shifts the price is, firstly, whether the engine has run and for how long; then how much AdBlue was put in; and finally where the car is and whether a van can get to it safely, which is easier on an open drive than in a tight spot behind Burngreen Hall.

For that in mind, each call from South Barrwood opens by asking the identical trio — what was put in, what quantity, if it ran — ahead of any figure.

Those replies shrink a range right down to a single number.

The price is given on the call, before a van sets off; settling up comes on the day, by card or by phone, with nothing upfront.

Plenty of insurance policies include misfuelling cover, so it's worth checking yours whilst we are on the way.
