# Avoiding AdBlue in a Diesel Tank in Peterculter: Why It Happens

AdBlue already in the diesel tank? Then put this page down for now, leave the ignition and motor off, and ring 0333 366 0103.

Caught before your motor runs, it is normally a drain and a thorough flush, done where your car is around Peterculter.

The remainder of this page explains why it occurs and how to ensure it does not — handy if you're reading ahead of time.

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

Diesel feeds the motor — but plenty of modern diesels seen about Peterculter and Kirkton of Maryculter carry another liquid too.

Your exhaust, not your engine, is where AdBlue goes: sprayed into the gas to fresh it, from its own tank.

Different tanks, separate fillers.

Under one flap, next to each other: that's the arrangement on many cars. Elsewhere, AdBlue's filler is beneath the bonnet or in the boot instead.

Filling the diesel side at the pump goes on all the time.

The AdBlue side is filled far less commonly, normally from a bottle, and normally by a person who has to stop and think where it goes.

The mistake lives in that gap.

## How does AdBlue in your diesel tank happen around Peterculter?

It is seldom carelessness. Three things tend to line up.

First, the warning. Low AdBlue triggers a warning from your car, and letting it run out means limp mode — hence a rushed top-up, maybe before work off Station Brae, perhaps at Black's Bar / Richmond Arms on the way home that evening.

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

And the bottle fits. A bottle with a spout goes into a diesel filler as easily as an AdBlue one, and so nothing stops the tip after it has started.

Whether it takes place in Stony Hill or the middle of Peterculter, it's the same few seconds.

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

A few seconds is all the checks take — so run through them before you tip anything, on a driveway in Mid Anguston or a forecourt around Peterculter.

- Where it sits can mislead; the cap does not. AdBlue ones tend to be blue or bear the name "AdBlue" — diesel ones normally do not.

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

- Check inside your fuel flap: plenty of vehicles have a label there saying which fuel goes where.

- In your boot or under the bonnet: that's where your filler sits if it's not by the diesel cap, and the handbook tells you which.

- Picking up a hire or company car, perhaps at the car park at Portlethen? Check with whoever drove the car last before leaving, rather than once the light goes on.

## Topping up AdBlue without it reaching your diesel tank

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

- Not in a rush on the side of North Deeside Road, not on a slope, not with the engine running: park then switch off first.

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

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

- Finish when your tank is topped up or the bottle is empty; until then, tip gently through its built-in spout.

- Close the cap and check again. Make sure the diesel cap was never opened. Only then start your car.

If at step two or three you find you have already poured into the diesel side, stop there.

Never go on to stage five.

## Already put AdBlue in your diesel tank in Peterculter?

What follows is a short order of things, starting with not starting the engine.

Do not switch the ignition on; on many diesels that alone runs the fuel pump.

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

If you're on a forecourt, whether it is the BP or the Tesco, ask the attendants to help push the car away from the petrol pump.

At home in Peterculter? So the vehicle stays put.

When your motor has run by now, stop somewhere safe and turn the vehicle off.

Peterculter sits over 50 miles from the M90; on it, use the next junction.

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

## Our arrival around Peterculter, and what occurs next

The van reaches the car anywhere it has come to rest — your own drive, beside Peterculter Parish Church, or by the local primary school.

Both the work and the price rest on three replies — which liquid, what quantity, and if it's run — so our technicians ask.

The quote is given over the phone, before any van leaves.

Draining the tank comes next, then a thorough flush of your system.

Not like petrol, AdBlue forms crystals and eats at certain fuel-system metals, and neither washes out unaided. Hence it matters more.

Once your filter has been cleaned — or renewed, where needed — fresh diesel is added, and then your car is tested.

After that our technicians fire it up and check it runs smoothly before we go.

If the engine has not run, the majority of jobs take about half an hour once we are there, using pumps that are safe on a working forecourt and quiet enough to use outside a house after dark.

No money in advance; you settle up that day. Afterwards, the VAT invoice and the report from the engineer go to you for the insurer.

It's worth looking at your insurance as the van travels to you: misfuelling cover is included with plenty of policies.

## AdBlue drains around Peterculter and across Aberdeen City

Being a village, Peterculter shares its vans nearby places — Coalford, Milltimber — all the way across AB postcodes and the surrounding area around them.

The van reaches you fastest with a postcode starting AB14 0.

The vehicle does not need to move.

Wherever it sits — beside Peterculter Library, in a layby en route to Peter's Heugh, on a drive — that is where it is drained.

Ring and ask rather than guessing if you're near a border, or somewhere hard to explain, like the back of Culter Village Hall.

## In short, for Peterculter people

Always, the cap; after that, the tip.
