# Kingswells: How Does AdBlue End Up in a Diesel Tank, and How Do You Prevent It?

AdBlue already in your diesel tank? In that case set this page down for now, keep the ignition and engine off, and ring 0333 366 0103.

Caught before your motor runs, it's normally a drain and a thorough flush, done where the vehicle is in Kingswells.

If you are reading before it has happened, the remainder of this page is about why it occurs and how to make sure it doesn't.

## Two fillers, two tanks: AdBlue in a diesel car

Not one fluid but two: that is what many newer diesels around Kingswells and Westhill run, with diesel for your motor.

Its own tank keeps it, and from there it is sent to your exhaust, and there a spray treats the fumes.

Separate tanks, different fillers.

Some motors put the AdBlue filler in your boot or under the bonnet; a lot of others place both together behind one flap.

The diesel side is fuelled at the pump all the time.

Seldom topped up, AdBlue usually comes out of a bottle, poured by someone who must stop and think which cap it needs.

Mistakes happen in that gap between them.

## AdBlue in your diesel tank around Kingswells: how it happens

Seldom is it carelessness: usually three things coincide.

Haste comes from the warning. Your car warns you as AdBlue runs low, and a dry tank sends it into limp mode — so the top-up happens in a rush, before work on a drive off Village Centre, or on the way home in the car park at The Smiddy.

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

Nothing stops the pour after it has started, since a bottle with a spout goes into a diesel filler as readily as an AdBlue one. The bottle fits.

The same few seconds settle it, in the middle of Kingswells or out in Newhills.

## How to tell the AdBlue filler from the diesel one

Look at these first, at a forecourt around Kingswells or a driveway over in Chapel of Stoneywood. Seconds, no more.

- The cap. The AdBlue cap is often blue, or marked "AdBlue". Your diesel cap usually isn't. Read it instead of going by where it sits.

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

- A label inside the fuel flap often says which fuel goes where, on plenty of vehicles. Look for it.

- The handbook shows which it lives when the filler isn't next to your diesel cap: your boot, or under the bonnet.

- Collecting a hire or company car, say at the car park at Dyce? Check with whoever drove the car last before you set off, not when the light goes on.

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

On the day the warning appears — anywhere you are around Aberdeen City — a simple routine to use.

- Park then switch off. Not on a slope, not with the motor running, and not in a rush on the side of Clova Crescent.

- Daft as it sounds, saying "AdBlue" out loud while you unscrew the cap does the trick — once you've found your filler and read the cap.

- The diesel cap remains on. When the two sit under a flap, make sure it is closed before the bottle comes up.

- Stop once your tank is topped up or the bottle is empty; before that, pour gently through its built-in spout.

- Close the cap and check a second time. Make sure the diesel cap was never opened. Only then start the car.

Find at step two or three that it's already gone into your diesel side? Then stop just there.

Never carry on to stage five.

## Kingswells: already put AdBlue in your diesel tank?

Don't start your motor: that is where the short order of things begins.

Keep your ignition off too, because on plenty of diesels it by itself starts your pump.

AdBlue does not mix with diesel — it sinks to the bottom of your tank, where your fuel is drawn from — so do not top up with diesel to dilute it.

On a forecourt — Esso, Tesco or another — the attendants will normally help push your car clear, when you ask.

If you are on your own drive in Kingswells, leave the car where it is.

Already run? Pull over once it is safe, then switch off.

Kingswells sits over 50 miles from the M90; there, use the first junction.

A short hop across Kingswells is a smaller job than a run towards Aberdeen, under 10 miles away, and so tell us about how far it went.

## When we arrive around Kingswells, what occurs?

By the local primary school, near Kingswells Community Centre or on your own drive: wherever the vehicle has stopped, our technicians come to it.

Which liquid got in, the amount, and whether it ran: our technicians ask because those answers decide both work and price.

You hear that price on the phone, before anyone heads out.

Next: draining, then a full flush of the whole system.

More than with petrol, it counts with AdBlue: the crystals form, some metals are attacked, and nothing washes away unaided, however long it sits.

The fuel filter is flushed, or replaced where it needs to be; fresh diesel goes in; and the vehicle is tested.

The motor is fired up next and tested to confirm it runs correctly, all before our engineers go.

With pumps safe on a busy forecourt and quiet enough for use outside a house at night, most jobs where the motor has not run take roughly half an hour once we arrive.

You pay on the day, with nothing upfront, and get a VAT invoice and an engineer report for your insurer.

Plenty of insurance policies include misfuelling cover, so it is worth checking yours while we're on the way.
