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

AdBlue in the diesel tank? Then keep your motor off — and your ignition as well.

In plain terms, AdBlue is simply urea in water.

It doesn't burn, it does not mix with diesel, and the damage it does starts when the fuel system draws it in.

If the motor has not run yet, AdBlue in a diesel tank is generally emptied and thoroughly rinsed where the vehicle sits around Mount Pleasant.

No step comes before calling 0333 366 0103.

## Those opening minutes: AdBlue in your diesel tank in Mount Pleasant

Things to do:

- So no one can turn the ignition on, pull the keys away.

- Put your hazards on if you are at all close to moving traffic.

- Which fluid, and roughly how much volume? Save the bottle or your receipt, and our engineers will see.

- Give us a postcode starting ST14 7, or whatever street is closest, and our van reaches you directly — so call from wherever you stand.

Never:

- Moving your car even a few yards is no reason to start the engine.

- Your ignition stays off: on many diesels, switching it on is enough to run your pump.

- AdBlue doesn't dilute in diesel — it separates out — so adding extra fuel will not thin it.

- Never drive the vehicle anywhere, not even a short stretch down New Street.

- No emptying it yourself, at all, at the verge.

Ask the people behind the counter to help you move your vehicle away from the island if you are at a forecourt around Mount Pleasant, whether it's the Tesco or somewhere else.

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

## What does AdBlue do in a diesel tank?

AdBlue is made for your exhaust, not your motor.

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

Nothing in it is supposed to pass through a fuel pump, and nothing in a fuel pump is designed to handle it.

It doesn't combine. Once it's tipped into the tank, AdBlue behaves not at all like diesel.

Heavier than diesel, it sinks and collects underneath it — the same place the pickup sucks from.

Simplest of all: a vehicle that had AdBlue in The Heath overnight and hasn't turned since. The AdBlue sits at the base of your tank, undrawn — but it would be the first thing through if your motor starts, ahead of any diesel at all.

It does two kinds of harm from there.

What remains once the water evaporates is urea, which turns into crystals: they lodge in tiny passages and clog filters. On top of that, it attacks some metals in a fuel system, and keeps going until it's flushed out.

A car left standing around Mount Pleasant with AdBlue already in its lines is worse by the morning; one with AdBlue only in its tank isn't.

Then there is the water: it brings no protection to the components that need it most — the high-pressure pump and every injector.

## Why AdBlue in a diesel is commonly more serious than petrol

A fault of thinned fuel is what you end up with after filling a diesel with petrol at the Esso.

It mixes with the diesel, and while it's inside your tank it does no damage; the damage comes from running the engine on it.

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

It doesn't burn, and so it cannot simply be run through.

Nor can it be thinned, since it separates again — and the following fill will not clear away crystals or corrosion. So the flush matters for more here, and turning your key "to see", in the centre of Mount Pleasant or out in Blounts Green, costs more than nearly any other slip.

The good news is the same as with petrol.

If the motor hasn't run, the AdBlue is still in that tank, and the tank is the quickest part of a fuel system to clear, wherever in Staffordshire your car is standing.

## How AdBlue ends up in a diesel tank in Mount Pleasant

It's not on purpose. Many cars keep the AdBlue inlet alongside the diesel inlet, occasionally behind a single flap, and muddling them up is easy in poor light.

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

Usually, it happens in one of a couple of familiar ways.

Halfway through the morning drop-off, the dashboard flags it up, and outside Picknalls First School the refill is rushed.

Near Amerton Place, a driver tips a bottle in at home after work.

Or someone unfamiliar with that flap tops up the vehicle after dark, stopped in the car park by Black Dog Jazz Cafe.

It comes up the most in a rental, a new car, a fleet motor, or the spare motor in a home with one of each fuel types — the vehicles people use the least.

Anywhere across Staffordshire, Mount Pleasant included, the slip does not change, and neither does the first response: leave it off.

## Started the motor with AdBlue in your diesel tank in Mount Pleasant?

The AdBlue has left your tank, then.

The filter and pipework have had it pulled along, and some running time takes it on to the injection pump and each injector.

Watch for lumpy running, exhaust smoke, falling power, warnings on your dash, or a cut-out — coming back from OldFields Sport Ground, say, or midway across Mount Pleasant.

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

With each start, more of that is pulled through.

On the M6, under 15 miles from Mount Pleasant, the next junction is where to leave, and anywhere safe is where to stop — not carrying on.

How far it went counts. A couple of hundred yards across Mount Pleasant to the car park by Dove Evangelical Free Church is a very different job from a run towards Lichfield, under 25 miles away, with the AdBlue reaching further into the system with every mile.

Tell us roughly how far it had come.

Once the motor has been started, the flush takes in more, and all of it is done where the vehicle has come to a stop.

When it is noticed quickly, long-term damage is very uncommon.

## Clearing AdBlue in a diesel in Mount Pleasant: what it takes

Our engineers come to the vehicle, wherever it has stopped in Mount Pleasant: a side street close to Uttoxeter Leisure Centre, a drive, a lay-by or a forecourt.

Three replies decide the work, and so first our engineers ask what went in, roughly what quantity, plus whether the motor has turned over.

Next, emptying the tank on the spot takes out the contaminated diesel along with the AdBlue together.

What remains from AdBlue will not wash away by itself, so the fuel system gets a careful flush, which matters far more here than with petrol.

A test of your car comes at the end, once clean diesel is added and the fuel filter is cleaned or, where needed, replaced.

About half an hour on site is typical for most jobs when the motor has not run.

The pumps are explosion-proof, safe on a working forecourt and quiet enough to use outside a house after dark.

New diesel goes in to prime your system, and that is the final step.

After that our technicians start the engine and you head off, whether from a parking space outside Uttoxeter or a driveway around Mount Pleasant.

Before we leave, we check it is running correctly with fresh diesel in.

The entire job is done where your car is, so it never has to go to a workshop.

Insurers ask for a VAT invoice and an engineer report, and you get both afterwards.

## Mount Pleasant and Staffordshire: AdBlue drains across the area

Our vans that answer AdBlue calls around Mount Pleasant also cover the locations round it, Uttoxeter, The Wharf and Balance Hill among them, and most of Staffordshire beyond, across the ST postcode area.

If you're close to a boundary, or somewhere hard to explain, ring and ask rather than assuming.

No towing is needed. In Mount Pleasant, a residential suburb, a mobile service fits: the vehicle is emptied where it stands, whether in a driveway, a side street, a parking area or a filling station.

## Mount Pleasant: what AdBlue in a diesel tank costs to fix

There is no fair single price, since the jobs aren't the same.

What shifts the cost is, first of all, whether the motor has run and for how long; then how much AdBlue went in; and then where your car is and whether a technician can reach it safely, which is easier on an open drive than in a tight space behind Redfern Cottage.

With that in mind, each call from Mount Pleasant begins with the same trio — which fluid went in, what quantity, whether the engine ran — before any quote.

Those replies turn a range into a straight price.

Our price is quoted on the call, before anyone leaves; payment happens on the day, by card or over the phone, with nothing upfront.

Misfuelling cover is part of many insurance policies, so it is worth looking at yours before the van arrives.

## Still alongside the vehicle around Mount Pleasant?

Then, touch nothing — that is the most helpful step there is.

Ignition off, engine off, keys out.

Petrol in Diesel takes over the rest, across Mount Pleasant or wherever in Staffordshire, once you call 0333 366 0103 to say it's AdBlue, about how big an amount, and if the engine ran.
