# AdBlue in a Diesel Tank in West Curry? Don't Start It

If AdBlue has gone into the diesel tank, leave your engine off then leave your ignition off.

Chemically, AdBlue is just urea in water.

Being water-based, it won't ignite and never combines with diesel; trouble just starts once your pump starts pulling it.

In West Curry, AdBlue in a diesel tank caught before your motor runs normally means a drain and a thorough flush, just where your car is.

Before anything, phone us on 0333 366 0103.

## Your next steps right now, West Curry: AdBlue in the diesel tank

Do these:

- Keys out — then nobody can switch anything on.

- If you're anywhere near moving traffic, put the hazards on.

- Which product, and about how much volume? Hang on to the bottle or the till receipt, and we can know.

- Call us from where you are. A postcode starting PL15 8, or the name of the nearest street, gets our van to you without a search.

Not to do:

- Do not start the engine, even for a moment to shift the car.

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

- No extra fuel added. The AdBlue will not blend, so it's wasted.

- Any driving at all is best avoided, including a short way up Braggs Hill.

- Draining your tank on your own beside the road is not worth trying.

Ask the attendants to help you roll your car away from the pumps if you are on a forecourt around West Curry, whether it's the the nearest petrol station or somewhere else.

If you are on your own drive, leave the vehicle just where it is.

## AdBlue in a diesel tank: what it does

Made for your exhaust, AdBlue has no place in the engine.

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

Nothing inside an injection pump is made for this liquid — and none of that was meant to go through one.

Inside a diesel tank it behaves very differently from fuel. It does not mix in.

The intake takes fuel from the lowest part of your tank, and that's just where AdBlue settles: as it is denser than diesel, it sinks.

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

Two kinds of damage come from there.

What remains once the water evaporates is urea, which forms crystals: they lodge in tiny passages and clog filters. Worse, it attacks some metals in a fuel system, and keeps going till it's cleared out.

Lines carrying AdBlue spell damage by morning for a vehicle sitting in West Curry. Just inside your tank, it stays the same.

Water lubricates nothing. The injection pump and each injector depend on diesel flowing through them, so the water content harms them by itself.

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

Put petrol in a diesel at the another forecourt nearby and you have an issue of thin fuel.

No damage is done while it stays put, blended into the diesel — only when your motor works on it.

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

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

Whether your car is in Brazacott or the centre of West Curry, turning it over "to see" does more harm in this case than nearly any other mistake, and the flush matters for more. The reasons: it won't stay blended, so diluting it is impossible; and crystals and corrosion outlast the following tankful.

As with petrol, there is good news.

If your motor has not run, the AdBlue is still inside your tank, and the tank is the quickest part of a fuel system to clear, wherever around Cornwall the car is sitting.

## West Curry: how AdBlue ends up in a diesel tank

Plenty of cars put the AdBlue filler alongside the diesel cap, now and then behind one flap, and in dim light the two can appear the same. Nobody means it.

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

A couple of familiar ways account for the majority of them.

Halfway through the morning drop-off, the dashboard warns, and outside Boyton Community Primary School the refill is hurried.

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

Otherwise, in dim light outside the pub in the village, your vehicle gets topped up by someone using that flap the first time.

The least known cars see it most — hire cars, brand-new cars, company ones, and the other car of a home with both fuels.

Keep it switched off: that is the first step to an identical slip, wherever around West Curry or the remainder of Cornwall you are.

## Already started the motor with AdBlue in the diesel tank in West Curry?

If so, the AdBlue is no longer inside your tank.

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

Watch for rough running, exhaust smoke, falling power, lights on the dash, or a cut-out — returning from Westcott Wood, say, or midway across West Curry.

No restarting to check: stop once it is safe, then switch it off.

With each start, more of it is pulled through.

West Curry sits under 50 miles from the M5; if you were on it, exit by the first junction and pull up safely instead of driving on.

How far it went counts. A couple of hundred yards across West Curry to the car park by Maxworthy Methodist Church is a very different job from a run towards Plymouth, under 50 miles away, with the AdBlue reaching further into the system with each mile.

Tell us about how far it had come.

Our engineers do all of the rinsing where your car has stopped, and once the engine has run there is more of it.

When it is noticed quickly, lasting damage is very rare.

## Draining AdBlue in a diesel in West Curry: what it takes

The car remains where it is, whether that's a road near Church of the Holy Name, a driveway, a lay-by or a forecourt in West Curry, and the van comes to it.

Before anything else our engineers ask what was put in, about how much, and whether the motor has been run, because those answers settle this work.

Right there, your tank is then emptied, and all of the contaminated diesel and the urea come out at once.

Residue from AdBlue won't wash out unaided, so the fuel system gets a careful flush, which matters far more with urea than for petrol.

Next, the filter: cleaned, or changed if it must be. After that clean diesel, then a check of the vehicle.

Roughly half an hour on site is usual for most jobs when your motor has not run.

The equipment is explosion-proof, so a live filling station is no issue, and it's hushed enough for a residential street late at night.

Finally, the system is primed with fresh diesel.

Whether it is a parking bay at the nearest station or a driveway in West Curry, that is where our engineers start the car and you set off.

We make sure it runs smoothly on new diesel before leaving.

We do it all wherever the vehicle has stopped, and it never has to go to a garage.

Insurers ask for a VAT invoice and an engineer report, and both come at the end.

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

West Curry is a small village, and a call-out drain suits it: whether the car is on a home drive, a residential street, a car park or a forecourt, our engineers drain it where it stands, so it never needs to be shifted to us.

## AdBlue in a diesel tank in West Curry: the cost of fixing it

Not one flat figure would be honest, because each job is different.

Whether the engine has run, and for how long, comes first in what shifts the cost. How much AdBlue went in comes next, and then the location of your car, because an open drive is simpler for a technician to reach safely than a tight spot behind St Paternus.

With that reason, every call from West Curry opens with the identical trio — what went in, what quantity, if the engine ran — before a figure.

With those replies, the range shrinks to one firm figure.

Our quote is quoted during the call, before a van leaves; payment comes on the day, by card or by phone, with nothing upfront.

As the van is travelling, check your policy: plenty cover misfuelling.

In that case, touch nothing — that's the most helpful step available.
