# Gidlow: AdBlue in the Diesel Tank? Leave It Off

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

Water with urea dissolved in it: that is AdBlue.

The trouble starts once it is sucked through your pump — it won't ignite, and it will not blend with diesel.

A drain and a thorough flush, done where the car is in Gidlow, is usually what AdBlue in a diesel tank needs — if it is caught before your engine has been run.

First, call us on 0333 366 0103.

## Your next steps straight away, Gidlow: AdBlue in the diesel tank

To do:

- Remove the keys, which stops anyone turning the electrics on.

- Hazards on, if moving traffic is anywhere near.

- Keep the receipt or the empty bottle, and so you can tell us what went in and roughly how much.

- The van finds you quickest with a postcode starting WN6 7, or simply the name of a street nearby, and so call from the car.

Not to do:

- Do not start your motor, even for a moment to move the car.

- Many diesels run their pump the moment your ignition goes on, and so keep it off.

- Adding more diesel doesn't help: AdBlue settles out rather than blending.

- Even a short distance along Hodges Street is too far to drive the vehicle.

- By the road, do not attempt emptying it on your own.

At a forecourt around Gidlow, whether it's the Esso or another one, ask the attendants to help you roll the vehicle clear of the pump.

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

## What does AdBlue do in a diesel tank?

Not the engine but your exhaust is where AdBlue is meant to go.

Its own reservoir keeps it, and from there it's sprayed into the exhaust, and there it treats the gas.

Not one side fits the other: urea does not belong in an injection pump, and an injection pump cannot deal with urea.

Fuel blends; AdBlue, once poured in, will not. The behaviour is nothing like fuel's.

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

When the pump runs, the AdBlue is top of the list to go through. Until then it sits underneath the diesel, which is why a vehicle topped up in Beech Hill last night and not switched on stays the straightforward case, provided no one turns your key.

From there it causes two kinds of damage.

Crystals and corrosion. As the water dries, it strands urea that crystallises in filter elements and narrow passages; and, because it eats at some metals, every part it reaches suffers for as long as it stays inside.

Pipes holding AdBlue mean harm overnight for a vehicle parked around Gidlow. Only inside that tank, it stays the same.

And there is the water: it offers no lubrication to the parts that need it most — the high-pressure pump and every injector.

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

Fill a diesel with petrol in error over at the Tesco, and this issue is diluted fuel.

It mixes with your diesel, and whilst it is in that tank it does no damage; the harm comes from running your motor on it.

AdBlue in a diesel is a different matter: not thin fuel, but no fuel at all.

It does not burn, so it cannot simply be run through.

It does not stay mixed, so it cannot be diluted. And crystals and corrosion don't wash out with the next tank of fuel. That is why the flush counts more with AdBlue than with petrol, and why starting your motor "to see" costs more here than nearly anywhere else, whether the car is in Bull Hey or the middle of Gidlow.

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

If your motor has not run, the AdBlue is still inside your tank, and the tank is the simplest part of a fuel system to clear, wherever in Greater Manchester your car is sitting.

## How AdBlue ends up in a diesel tank in Gidlow

After dark, two caps side by side — the AdBlue cap and the diesel cap, occasionally under one flap — can appear the same. Nobody intends it; plenty of designs invite it.

A container bought while driving home and poured in outside the house, rather than at the filling station, is the typical route.

A few familiar ways account for the majority of them.

The top-up gets hurried outside Sacred Heart Catholic Primary School, after your dash flashed with a warning as the kids were taken off.

A driver pours the bottle in outside their house, right off Barnsley Street, as the day ends.

Or a driver new to that flap tops up your car after dark, parked in the car park outside The Springfield.

Rented vehicles, brand-new cars, fleet cars, or the second car in a family with both fuels: the least familiar cars get it the most.

Wherever around Greater Manchester, Gidlow included, the slip doesn't change, and nor does the first step: keep it off.

## Started the engine with AdBlue in the diesel tank around Gidlow?

Then the AdBlue has left that tank.

Your filter and lines have had it pulled through, and any running time carries it on to the injection pump and each injector.

Maybe returning from Pateley Square, or midway across Gidlow, your motor might run lumpy, smoke, lose pace, flash the dash or stall.

No starting it again to test: pull over once it is safe, then turn everything off.

Every start pulls more of that through.

On the M6, under 3 miles from Gidlow, the next junction is where to exit, and anywhere sensible is where to park — not driving on.

A quick hop across Gidlow to the car park by Gidlow Methodist Church is one matter; driving for Preston, under 15 miles away, is something else, since every mile carries the AdBlue further in. So mileage counts.

About how far it had come is worth telling us.

Wherever the vehicle came to a stop is where all of it gets done, even with more to flush once your engine has been run.

When it's caught early, permanent damage is very uncommon.

## What emptying AdBlue from a diesel involves in Gidlow

A road by Book-Cycle Beech Hill, a driveway, a layby or a forecourt: anywhere the vehicle has stopped in Gidlow, our engineers come to it.

The work rests on three answers, which our technicians ask for first — which fluid got in, the quantity, and whether the engine has run.

Right there, the tank is then emptied, and both the polluted diesel and the urea come out at once.

With AdBlue, far more than with petrol, flushing counts: the whole system is cleaned all the way through since residue won't wash out by itself.

Testing your car follows at the end, once fresh diesel goes in and the filter is cleaned or, where necessary, swapped.

The majority of these jobs are a half-hour job once our engineers arrive, provided the motor has not run.

Quiet enough to use outside a house at night, and fine on a working forecourt, the pumps are explosion-proof.

Bleeding your system with new diesel comes at the end.

You head off as soon as our engineers have fired it up, and it makes no difference whether your car is on a driveway in Gidlow or in a bay at Wigan Wallgate.

We make sure it runs smoothly on clean diesel before we go.

Since the job is done in full where your car is, a workshop never comes into it.

Insurers want a VAT invoice and an engineer report, and both come afterwards.

## Gidlow: what AdBlue in a diesel tank costs to fix

Not one flat price could be fair, since each job differs.

Whether the motor has been running, and for how long, comes first in what changes the cost. How much AdBlue went in comes next, and then the location of the vehicle, since an open driveway is simpler for a technician to reach safely than a tight spot behind Sacred Heart Parish Centre.

Before a quote, not afterwards, every enquiry from Gidlow begins with three questions: the fuel, the quantity, and whether it ran.

The replies turn a range into a straight quote.

You get that quote on the phone, before anyone sets off, and you pay on the day, by card or by phone, with nothing upfront.

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