# AdBlue in the Diesel Tank in Hockley Heath? Keep It Switched Off

With AdBlue in your diesel tank, your ignition stays off and so does your motor.

Water with urea dissolved in it: that's AdBlue.

Unlike fuel, it neither burns nor blends, and nothing starts until the motor sucks it round.

If the engine hasn't run yet, AdBlue in a diesel tank is normally drained and carefully purged where the car stands around Hockley Heath.

No step comes before calling 0333 366 0103.

## AdBlue in your diesel tank around Hockley Heath: the first few minutes

Do these:

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

- Hazards on, if moving traffic is at all close.

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

- Tell us a postcode starting B94 6, or whatever street is nearest, and our van finds you directly — so call wherever you stand.

Do not:

- No starting your motor — not briefly, not to reposition the car.

- Do not switch your ignition on. On many diesels that alone runs the fuel pump.

- No more fuel on top. The AdBlue won't mix, so it's pointless.

- Keep it where it is instead of driving it anywhere, even a short way along Shelfield Close.

- By the road, don't attempt emptying it on your own.

Moving your car away from the pumps is a job for staff to help with, wherever Hockley Heath forecourt you're on, the Shell or any other.

Stopped on your own drive? Then it stays just as it is.

## What AdBlue does in a diesel tank

AdBlue is made for your exhaust, not the motor.

From a separate tank it goes straight to the exhaust, cleaning what the motor emits.

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

Fuel blends; AdBlue, after tipped in, will not. Its behaviour is nothing like fuel's.

It drops, since it's heavier than diesel, and settles down where the pickup takes its supply from.

The first thing your fuel system pulls through, after it runs, is the AdBlue. So a car that had AdBlue poured in on a drive in Packwood last night, and hasn't been started since, is still the simple case: the AdBlue is lying at the bottom of that tank, and nothing has drawn it in.

From there it causes two kinds of harm.

What remains once the water evaporates is urea, which forms crystals: they lodge in tiny channels and block filters. On top of that, it eats at certain metals in a fuel system, and keeps going till it is flushed out.

Where the AdBlue is in the pipework, leaving it till morning around Hockley Heath makes it worse. Inside your tank alone, waiting costs nothing.

And there is the water: it offers no lubrication to the components that rely on it the most — the injection pump and each injector.

## Why is AdBlue in a diesel regularly the bigger fault?

An issue of thinned fuel is what you end up with after fuelling a diesel with petrol at the Sainsbury's.

Damage just comes from running on it. Mixed into the diesel and left in your tank, it causes nothing.

The issue with AdBlue in a diesel is a totally wrong liquid.

Not burning, it cannot simply be run through.

It doesn't stay mixed, so it cannot be weakened. And crystals and corrosion do not wash out with the next tank of fuel. That's 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 vehicle is in Packwood Gullet or the middle of Hockley Heath.

The same good news applies as with petrol.

Emptying a tank is the simplest job on any fuel system, and without start-up, the AdBlue stays in there — anywhere in West Midlands the car sits.

## AdBlue in a diesel tank around Hockley Heath: how it ends up there

In dim light, two caps together — the AdBlue one and the diesel cap, now and then behind a single flap — may appear the same. Nobody intends it; many designs invite it.

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

It tends to happen in a few familiar ways.

Hurrying, outside Tudor Grange Primary Academy Hockley Heath, after a warning lamp flashed on during the school run, a parent tops up the car.

A driver tips the container in outside their house, right off Arden Meads, as the day ends.

Another version: dim light, a pub car park by The Wharf Tavern, and a driver opening that flap for the first time.

It crops up the most in a hire car, a new car, a company car, or the other car in a home with one of each fuels — the cars drivers know least.

Leave it switched off: that is the first response to an identical slip, anywhere around Hockley Heath or the rest of West Midlands you are.

## Started the engine with AdBlue in the diesel tank around Hockley Heath?

If so, the AdBlue is no longer in that tank.

Given any running, it goes on to the injection pump and each injector, after passing via the filter and lines.

You may see your motor running unevenly, smoking, losing power, showing warning lights or cutting out, possibly on the way back from Hockley Heath Recreation Ground or halfway across Hockley Heath.

Stop as soon as it is safe, switch off, and do not restart the car to check.

Each start pulls more of it through.

Hockley Heath lies under a mile from the M40; if you were on it, leave at the next junction and pull up somewhere safe rather than carrying on.

How far it went counts. A few hundred yards across Hockley Heath to the car park by War Memorial is a very different job from a run towards Birmingham, under 15 miles away, with the AdBlue reaching further into the fuel system with each mile.

Approximately how far had it come? Tell us.

We do all of the cleaning where the vehicle has ended up, and once the engine has been started there is more of it.

Caught soon, it very seldom leaves lasting damage.

## What draining AdBlue from a diesel involves around Hockley Heath

Wherever it has come to rest in Hockley Heath — a filling station, a layby, a drive, a road by St Thomas — the van travels to your vehicle.

The work rests on three replies, and we get before all else — what was put in, the quantity, and whether the engine has run.

Next, emptying your tank right there removes the polluted diesel along with the AdBlue together.

What remains from AdBlue won't wash out unaided, and so the whole system gets a careful flush, which matters far more with urea than with petrol.

A test of your car follows last, once fresh diesel is added and the filter gets flushed or, if needed, swapped.

Roughly half an hour on site is typical for most jobs where your engine has not run.

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

New diesel goes in to bleed the fuel system, and that's the final step.

At that point our technicians start the engine and you head off, whether from a parking bay at Dorridge or a driveway around Hockley Heath.

It's checked on clean diesel to make sure it runs smoothly before our engineers head off.

Our technicians do it all wherever the car has ended up, and it never needs to be taken to a workshop.

You receive a VAT invoice and an engineer report later, which is what insurers want.

## AdBlue in a diesel tank around Hockley Heath: the cost of fixing it

There is no fair single quote, since the jobs are not the same.

What shifts the cost is, firstly, whether the motor has been running and for how long; then how much AdBlue got in; and after that where the vehicle is and whether our van can reach it safely, which is simpler on an open driveway than in a tight spot behind Hockley Heath Baptist Church.

Ahead of any figure, never after, each enquiry from Hockley Heath begins with three checks: the fuel, the quantity, plus whether the engine ran.

Those answers turn a range into a straight quote.

You get that quote by phone, before anybody heads out, and you pay on the day, by card or by phone, with nothing upfront.
