# Don't Start It: AdBlue in a Diesel Tank in Loughborough

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

Urea dissolved in water is what AdBlue is.

Not like fuel, it neither ignites nor mixes, and no harm happens till the engine sucks it round.

If your motor hasn't run yet, AdBlue in a diesel tank is normally drained and carefully cleaned where your car stands around Loughborough.

Before you do anything else, call 0333 366 0103.

## Your next steps straight away, Loughborough: AdBlue in your diesel tank

To do:

- So no one can turn your ignition on, pull your keys out.

- Hazards on, if moving traffic is anywhere near.

- So you can give us which liquid it was and about what quantity, keep the receipt or the empty bottle.

- Ring us from where you are. A postcode starting LE11 2, or the name of the closest street, brings the van to you without a search.

Things not to do:

- Shifting your car even a few yards is no reason to start your motor.

- Plenty of diesels run their pump the instant your ignition goes on, and so leave it off.

- AdBlue does not mix in diesel — it separates out — so adding more fuel won't weaken it.

- Never drive the vehicle anywhere, not even a short distance down Market Place.

- Emptying that tank on your own beside the road isn't one to try.

Get the attendants to help you roll the vehicle off the pumps if you're at a forecourt around Loughborough, whether it's the Sainsbury's or somewhere else.

Stopped on your own driveway? Then it remains just as it is.

## AdBlue in a diesel tank, and what it does there

Meant for your exhaust, AdBlue has no place in your engine.

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

Not one side suits the other: urea doesn't belong in a pump, and an injection pump can't deal with urea.

Inside a diesel tank it behaves very differently from fuel. It doesn't mix in.

Heavier than diesel, it drops and collects underneath it — the same spot the pickup sucks from.

A vehicle topped up on a driveway in Cotes overnight and left unstarted counts as the straightforward case. Nothing has sucked the AdBlue up so far — though when the motor runs, that is what is pulled first, directly from the bottom of the tank.

From there it does two kinds of harm.

Crystals and corrosion. As the water dries, it leaves urea that hardens in filters and narrow channels; and, because it attacks some metals, each part it touches suffers for as long as it stays inside.

Lines carrying AdBlue spell damage overnight for a car sitting around Loughborough. Just in your tank, it stays stable.

Water lubricates nothing. The injection pump and each injector need diesel running through them, and so the water content harms them in its own right.

## Why AdBlue in a diesel is regularly more major than petrol

Top up a diesel with petrol in error over at the Shell, and the issue is diluted fuel.

Mixed into your diesel and sitting unused, it's harmless for now; running your engine does the harm.

The issue with AdBlue in a diesel is a totally unsuitable substance.

Not burning, it can't just be run through.

Nor can it be thinned, because it separates back out — and the following fill won't rinse away crystals or corrosion. So the flush matters more with AdBlue, and turning the key "to see", in the heart of Loughborough or out in Woodthorpe, costs more than nearly any other error.

The same good news applies as with petrol.

If your engine has not run, the AdBlue is still inside your tank, and that tank is the quickest part of a fuel system to clear, wherever across Leicestershire the car is standing.

## AdBlue in a diesel tank in Loughborough: how it ends up there

Many motors put the AdBlue cap beside the diesel one, occasionally behind a single flap, and after dark the two can look identical. Nobody intends it.

Most of the time it happens with a bottle bought on the way home and poured in on the driveway, not at the pump.

A few familiar ways account for the majority of them.

Rushing, outside Cobden Primary School & Community Centre, after a warning lamp came on during the school run, someone tops up your car.

Someone tips the bottle in at home, just off Biggin Street, as the day ends.

Else, after dark by Loughborough Arms, your car is topped up by a driver opening that flap the first time.

The least known vehicles get it most — rentals, brand-new ones, company ones, and the other car in a family with one of each fuel types.

Keep it switched off: that's the first response to the same slip, anywhere in Loughborough or the rest of Leicestershire you happen to be.

## Loughborough: started the motor with AdBlue in your diesel tank?

The AdBlue has left your tank, then.

Via the filter, along the pipework, and — given any running time — into the injection pump and each injector: that is where it has gone.

You may notice your engine running unevenly, smoking, losing power, showing warning lights or cutting out, possibly on the way back from The Rectory Wildlife Garden or halfway across Loughborough.

Stop as soon as it is safe, switch off, and don't restart the car to check.

Each start pulls more of it through.

If you were on the M1, under 3 miles from Loughborough, come off at the next exit and stop somewhere safe instead of pressing on.

Each mile pushes the AdBlue further in. That is why a hop across Loughborough to park beside Church Gate Pedestrianisation and a drive of under 15 miles for Leicester are such separate jobs.

Tell us roughly how far it had come.

Our engineers do all of the flushing where the vehicle has come to a stop, and once the engine has been started there is more of it.

When it's spotted soon, lasting damage is very unusual.

## What emptying AdBlue from a diesel involves around Loughborough

Wherever it has come to rest around Loughborough — a filling station, a lay-by, a driveway, a street by Loughborough Market — our van comes to your vehicle.

What got in, about the quantity, and whether your engine has been run: our technicians check before all else, since those shape the job.

On the spot, your tank is then emptied, and all of the contaminated diesel and the urea leave at once.

With AdBlue, more so than with petrol, flushing matters: the whole system is cleaned all the way through since residue won't flush away unaided.

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

Not run? Then expect about half an hour once we are there for most jobs.

The pumping gear is explosion-proof, and so a live filling station is no problem, and it's quiet enough for a residential street late at night.

New diesel goes in to prime your system, and that's the last step.

Firing it up comes next, and then you drive off from where the car is parked, at the nearest station or on a driveway in Loughborough.

Before we leave, we make sure it is running correctly with new diesel in.

No workshop is required at any stage, with the whole job done on the spot.

The insurer will want an engineer's report and the VAT invoice — each handed over once the job is done.

## AdBlue drains across Leicestershire, Loughborough included

Throughout the LE postcode area, the teams taking AdBlue call-outs in Loughborough serve most of Leicestershire too, Shelthorpe, Dishley and Thorpe Acre included.

Near a border, or somewhere awkward to pin down? Checking is better than guessing, so ring.

Anywhere your car sits — a drive at home, a residential street, a car park, a forecourt — our engineers empty it on the spot, and there's no need to take it to us; which suits Loughborough, a riverside town, well.

## What does AdBlue in a diesel tank cost to sort out around Loughborough?

Not one flat price could be honest, because each job is different.

Whether the motor has been running, and for how long, comes first in what shifts the cost. How much AdBlue was put in comes next, and then the position of your car, because an open drive is simpler for our van to get to safely than a tight spot behind Fearon Fountain.

Which fluid was put in, what quantity, and whether it ran: every Loughborough enquiry begins with exactly those, before any quote, never after.

The replies turn a range into a straight quote.

Our quote is quoted on the call, before a van sets off; payment comes on the day, by card or by phone, and nothing upfront.

Many insurance policies include misfuelling cover, so it's worth checking yours while we are on the way.

## Alongside your car in Loughborough, right now?

Right now, the best thing to do with your car is to leave it.

Keys out, motor off, ignition off.

Petrol in Diesel handles the remainder, across Loughborough or anywhere in Leicestershire, after you call 0333 366 0103 saying it was AdBlue, roughly what quantity, and whether the engine ran.
