# AdBlue in the Diesel Tank in Canley Gardens? Keep It Switched Off

AdBlue in the diesel tank? Then leave the motor off — and the ignition too.

AdBlue is urea mixed in water.

Unlike fuel, it neither burns nor mixes, and nothing happens until your engine sucks it round.

A drain and a thorough flush, done where the car is around Canley Gardens, is generally all AdBlue in a diesel tank takes — if it's caught before the motor has run.

Before you do anything else, call 0333 366 0103.

## AdBlue in the diesel tank in Canley Gardens: the first few minutes

Do these:

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

- Close to moving traffic? So put the hazard lights on.

- Which fluid, and roughly how much quantity? Save the bottle or your receipt, and our technicians will know.

- Our van finds you fastest with a postcode starting CV5 6, or just the name of a street close by, and so call from the spot.

Don't:

- Not even for a second, and not to shift the vehicle: your engine remains off.

- Turning the key to ignition alone sets the pump going on many diesels. Avoid it.

- Pouring in extra diesel doesn't work: AdBlue settles out instead of thinning.

- Even a short way up Beechwood Avenue is too far to drive the vehicle.

- No draining it yourself, either, on the roadside.

The attendants working at any Canley Gardens filling station — the Esso among them — will usually help rolling it clear if you ask.

At your own driveway, don't touch it at all.

## What AdBlue does in a diesel tank

AdBlue is made for the exhaust, not the engine.

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

Nothing inside an injection pump is designed for this liquid — and none of it was meant to go that way.

It does not combine. After it is tipped into the tank, AdBlue acts not at all like fuel.

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

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

Two kinds of damage come from there.

What is left once the water goes is urea, which forms crystals: they settle in narrow channels and block filters. Worse, it attacks some metals in a fuel system, and carries on until it's flushed out.

If the AdBlue is in the lines, waiting overnight in Canley Gardens leaves it worse. In the tank alone, waiting does nothing.

And there is the water: it brings no protection to the parts that need it most — the injection pump and each injector.

## AdBlue in a diesel: why it's commonly worse than petrol

Petrol pumped into a diesel on Costco's forecourt makes the fuel thin — that's the main problem.

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

With AdBlue in a diesel, the liquid itself is simply the wrong one.

It does not burn, and so it can't just be run through.

Crystals and corrosion remain through the following tankful, and AdBlue splits back from the diesel, so thinning it can't work. That is why the flush matters so much, and trying your engine "to see" costs more here than nearly any other mistake — in Chapel Fields or the heart of Canley Gardens alike.

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

If your engine hasn't run, the AdBlue is still inside the tank, and that tank is the easiest part of a fuel system to clear, wherever across West Midlands your car is sitting.

## Canley Gardens: how AdBlue ends up in a diesel tank

No one means to do it. The AdBlue filler on plenty of motors waits right next to the diesel filler, occasionally under the same flap, and the two caps can look alike in poor light.

It mostly takes place at home, from a container grabbed en route home, rather than at the forecourt.

It tends to occur in a few familiar ways.

The refill gets rushed outside Earlsdon Primary School, because your dash lit up with a warning as the children were dropped in.

A bottle is poured in at the end of the day on a drive just off Rochester Road.

Or your car is topped up in the car park at Earlsdon Cottage, in poor light, by someone who has never opened that flap before.

Hired motors, new cars, fleet cars, or the second car in a home with both fuels: the least known cars get it the most.

Wherever across West Midlands, Canley Gardens as well, the mistake does not change, and nor does the first response: keep it switched off.

## AdBlue in the diesel tank in Canley Gardens, and the engine started?

Then your tank is no longer where the AdBlue is.

Through your filter, along the pipework, and — given any running time — on to the injection pump and each injector: that is where it travels.

Rough running, smoke from the exhaust, dropping power, dashboard lights or cutting out: each might show up, maybe part way across Canley Gardens or returning from Hearsall Golf Club.

No restarting to check: pull over when it is safe, then switch it off.

With each start, more of it is pulled through.

If you were on the M6, under 5 miles from Canley Gardens, come off at the next exit and stop somewhere sensible instead of pressing on.

Each mile carries the AdBlue deeper in. That's why crossing Canley Gardens to park near Parish Church of St Barbara, Earlsdon and a drive of under 3 miles towards Coventry are such different jobs.

Let us know roughly how far it had come.

There's more to flush once your engine has been started, and our technicians do all of it where the vehicle has stopped.

Long-term damage is very uncommon if it is spotted early.

## Emptying AdBlue in a diesel around Canley Gardens: what it takes

A road by Beechwood Tennis Club, a drive, a layby or a forecourt: anywhere your vehicle has stopped in Canley Gardens, our technicians travel to it.

Which fluid was put in, about how much, plus whether the motor has turned over: our technicians check first, since those shape the job.

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

The fuel system is cleaned thoroughly, which matters more with AdBlue than with petrol, since what it leaves behind doesn't rinse out on its own.

Testing your vehicle comes last, once fresh diesel is added and the filter is flushed or, if necessary, replaced.

Most of these jobs are a half-hour visit once we arrive, provided the motor has not run.

Quiet enough for use outside a house at night, and safe on a working forecourt, our pumps are explosion-proof.

The final step is to prime your system on new diesel.

You set off as soon as our engineers have started the engine, and it makes no difference whether the car is on a driveway around Canley Gardens or in a space outside Canley.

It is checked on new diesel to make sure it runs correctly before our technicians head off.

The whole job is done where your car is, so it never needs to go to a garage.

At the end, you are given the paperwork for the insurer: a VAT invoice plus a written report from the engineer.

A mobile service fits Canley Gardens, a residential suburb: you have no need to take the vehicle to us, since we empty it there, on a drive, a residential street, a parking area or a forecourt.

## What AdBlue in a diesel tank costs to put right in Canley Gardens

Every job is different, and so not one fixed quote is fair.

The cost shifts first with how long, if at all, the engine has been running, and next with the quantity of AdBlue that got in. After that it depends on where your car is and whether a technician can get to it safely, which is simpler on an open drive than in a tight spot behind Criterion Theatre.

That's why each call from Canley Gardens starts with the same three questions, asked before giving a figure, not after: what went in, how much, and whether it's run.

Those replies turn a range into a straight quote.

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

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

## In Canley Gardens and still next to your car?

Then, the best thing to do with your car is to not touch it.

Ring 0333 366 0103: AdBlue, roughly how much, plus if the engine ran are everything our engineers need. Petrol in Diesel handles the remainder throughout West Midlands, Canley Gardens too.
