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

Pause here for a moment when the diesel tank already holds AdBlue in it: ignition off, engine off, and phone 0333 366 0103.

Caught before the motor runs, it is generally a drain and a thorough flush, done where your car is in Cellardyke.

If you are reading before it has happened, the rest 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 how many modern diesels near Cellardyke and Kilrenny run, with diesel for the engine.

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

There is a filler for each tank.

Under one flap, side by side: that is the arrangement on many cars. Elsewhere, AdBlue's filler is under the bonnet or in your boot instead.

At the petrol pump, the diesel side is topped up all the time.

Someone who has to stop and think where it goes normally tops up the AdBlue side, from a bottle, and far less often.

Mistakes happen in the gap between them.

## Cellardyke: how AdBlue in the diesel tank takes place

Three things tend to line up, and carelessness is rarely one of them.

On a drive off Urquhart Wynd before work, or in the car park outside Ship Tavern on the way home: that is where the rushed top-up takes place. What is the reason for the rush? As AdBlue gets low your car tells you, and once it's gone, limp mode kicks in.

Then, the hand goes for the cap it knew on the old vehicle — because a rental car, a new motor or a company car places the fillers somewhere your last one did not.

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

It takes a few seconds, whether in Anstruther or bang in the centre of Cellardyke.

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

Whether a Cellardyke forecourt or a driveway over in Pittenweem, spend a couple of seconds over these before any is poured in.

- Read the cap instead of going by where it sits: AdBlue caps are commonly blue or marked "AdBlue", and diesel ones usually are not.

- Many motors give AdBlue the smaller filler of the two.

- Lift the filler flap and check for a label — many cars show which goes in each filler just there.

- The handbook. If the filler isn't by the diesel cap, it's in your boot or under the bonnet, and the handbook says which.

- Collecting a hire or company car, perhaps at the car park at North Berwick? Check with whoever drove the vehicle last before you set off, rather than when the light goes on.

## Keeping AdBlue out of the diesel tank when you top up

When the light goes on, anywhere across Fife, use this routine.

- Switch off after you park — level ground, engine stopped, and not in a rush by George Street at the roadside.

- Find the AdBlue filler, check the cap, and speak the name "AdBlue" aloud as you unscrew it. It seems silly. It works.

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

- Using the bottle's own spout, pour slowly — and stop when it's full or the bottle is empty.

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

Find at step two or three that it has already gone into your diesel side? So stop just there.

Step five stays out.

## Cellardyke: already put AdBlue in the diesel tank?

What follows is a short order of things, beginning with no starting your motor.

Leave your ignition off too, since on many diesels it alone runs your pump.

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

The staff at Gulf, another forecourt nearby or another forecourt will usually lend a hand pushing the car clear if asked.

Leave it where it is if you are on your own driveway around Cellardyke.

Stop as soon as it is safe then switch off, if your motor has already run.

Leave the M90 — under 50 miles out of Cellardyke — at the next junction.

Tell us about how far it went: a run towards Dundee, under 25 miles away, is a bigger job than a short hop across Cellardyke.

## Cellardyke: what happens when our technicians arrive

We come to your car wherever it has stopped, whether that is outside the local primary school, near Mercat Cross or on your own drive.

Which liquid got in, the amount, and if it ran: our engineers ask since the replies set both work and price.

The price comes on the call, ahead of any van leaving.

Then your tank is emptied and the system rinsed thoroughly.

Not like petrol, AdBlue leaves crystals and eats at some fuel-system metals, and neither clears away unaided. Hence it counts more.

Testing comes at the end: before that, fresh diesel goes in, and the filter is cleaned or changed if necessary.

We do not leave until it has been fired up and is running correctly.

With pumps fine on a busy forecourt and quiet enough to use outside a house at night, most jobs in which your engine has not run take about half an hour once our technicians arrive.

Payment happens on the day, not upfront, and you receive the documents an insurer asks for: an engineer report and a VAT invoice.

Misfuelling cover is included in plenty of insurance policies — so make use of the wait to check yours.
