# AdBlue in a Diesel Tank in Spinney Hills: How It Happens and How to Stop It

AdBlue already in the diesel tank? In that case set this page aside for now, leave the ignition and engine off, and call 0333 366 0103.

Caught before the motor runs, it's usually a drain and a thorough flush, done where the vehicle is around Spinney Hills.

The rest of this page explains why it happens and how to make sure it doesn't — useful if you're reading before it has happened.

## AdBlue in a diesel motor: two tanks, two fillers

Diesel feeds the motor — but plenty of newer diesels seen about Spinney Hills and Crown Hills carry a second fluid too.

AdBlue's own tank keeps it, and from there it goes to the exhaust, and there a spray cleans the gas.

Different tanks, different fillers.

On a lot of vehicles the two sit side by side under the same flap; on others the AdBlue filler is in your boot or under the bonnet.

Filling the diesel side at the petrol pump goes on constantly.

Far less frequently, the AdBlue side gets topped up — normally from a bottle, by a person working out where it goes.

The error lives in that gap.

## How does AdBlue in your diesel tank happen in Spinney Hills?

Seldom is it carelessness: usually three things coincide.

First, the warning. Low AdBlue brings a warning from the car, and running out means limp mode — hence a rushed top-up, maybe before work off St Saviour's Road, perhaps at Rifle Butts on the way home that evening.

Then your car is unfamiliar. A hire car, a new vehicle or a company car puts the fillers where your last one did not, and your hand reaches for the cap it would have used on the old one.

Lastly, the spout goes in: a diesel filler or AdBlue filler, it goes in as readily, and once the pour starts, no part stops it.

Whether it happens in North Evington or the middle of Spinney Hills, it is the same few seconds.

## The AdBlue filler and your diesel filler: telling them apart

A couple of seconds is all these take — so check them before you pour anything, on a driveway in Leicester or a forecourt in Spinney Hills.

- Position misleads; the cap doesn't. AdBlue ones tend to be blue or bear the name "AdBlue" — diesel caps normally do not.

- The size. On plenty of cars the AdBlue filler neck is the smaller of the two.

- Look inside the fuel flap: many vehicles have a label there showing which fuel goes where.

- The handbook says where it is if the filler is not next to the diesel cap: your boot, or under the bonnet.

- Check with the person who drove it last — before you leave, not when the light comes on — if you pick up a hire or company car from somewhere like the car park at Leicester.

## AdBlue top-ups that never reach your diesel tank

For the day the warning comes on — anywhere you are around Leicestershire — a routine to use.

- Not in a rush on the side of Halstead Street, not on a slope, not with your engine running: park then switch off properly.

- Say "AdBlue" out loud as you unscrew the cap, after you find the AdBlue filler and read it. Daft, perhaps, yet it works.

- Leave the diesel cap on. If both sit under one flap, check your diesel cap is still closed before you lift the bottle.

- Tip slowly, using the bottle's own spout. Stop when it's full or when the bottle is empty.

- Close the cap, then look again — making sure the diesel filler stayed closed the whole time. After that, start the car.

Find during the second or third step that AdBlue went into the diesel filler? That's where you stop.

Never carry on to step five.

## Already put AdBlue in your diesel tank around Spinney Hills?

Do not start the motor: that's how the short order of things starts.

Don't switch the ignition on; on plenty of diesels that alone runs the fuel pump.

Don't top up with diesel to thin it: AdBlue doesn't mix with diesel, it sinks to the bottom of that tank, where the fuel is drawn from.

If you are at a forecourt, whether it's the the nearest petrol station or the Gulf, ask the attendants to help push the car clear of the pump.

## Spinney Hills: what occurs when our technicians turn up

By Spinney Hill Primary School, near Wesley Hall Methodist Church or on your own drive: wherever the car has stopped, our technicians come to it.

The replies decide the work and the price, so our engineers ask what went in, roughly how much, and whether it's run.

That price is given over the phone, before any van leaves.

Emptying that tank comes next, then a full flush of the system.

With AdBlue that matters more than with petrol: it crystallises and is corrosive to some of the metals in a fuel system, so it doesn't wash out on its own.

The filter flushed or, where needed, replaced; clean diesel in; and then a test of your car.

Before we leave, our engineers fire it up and confirm that it's running properly.

Unrun cars usually need a half-hour job from arrival. The equipment is safe on a busy filling station, and quiet enough for a driveway late at night.

The insurer will ask for the engineer's report and the VAT invoice, and both are yours at the end. Payment comes on the day, with no deposit.

Before we get there, take a look at your insurance documents; many carry cover for misfuelling.
