# Preventing AdBlue in a Diesel Tank in Bruntsfield: Why It Happens

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

Usually, if the engine hasn't run, it's emptied and fully rinsed where the vehicle is around Bruntsfield.

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

Many modern diesels in Grange Park, like those in Bruntsfield, carry on two fluids; the engine takes just the diesel.

Stored in a tank of its own, AdBlue is fed into your exhaust stream to clean it.

Every tank comes with one filler of its own.

Many of cars share a single flap for both, whereas others put the AdBlue filler to the boot or under the bonnet.

At the petrol pump, the diesel side gets filled all the time.

Seldom topped up, AdBlue usually goes in out of a bottle, poured by a driver who must stop and think which cap to use.

The slip lives in that gap.

## How does AdBlue in your diesel tank occur around Bruntsfield?

Rarely is it carelessness: usually three things line up.

To start with, the warning. Low AdBlue brings a warning from your car, and running out leads to limp mode — so a hurried top-up, perhaps before work off Greenhill Place, perhaps at The Merlin on the way home that evening.

Then your car is unfamiliar. A hire car, a new motor or a company car puts the fillers where your last one didn't, and the hand reaches 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, so nothing stops the pour once it has started.

The same few seconds decide it, in the middle of Bruntsfield or out in Churchhill.

## Telling the AdBlue filler from your diesel filler

Before you tip anything, whether on a driveway in Sciennes or a forecourt around Bruntsfield, check these. They take a few seconds.

- Read the cap rather than going by where it sits: AdBlue caps are often blue or marked "AdBlue", and diesel caps normally are not.

- On many motors, the size tells: AdBlue gets the smaller filler neck.

- Open the filler flap and look for a label — many vehicles show which goes in which inlet right there.

- The handbook. If your filler is not by the diesel cap, it is in the boot or under the bonnet, and the handbook says which.

- Whoever had it before will know. Ask as you collect a hire car or fleet car — from Haymarket's car park, perhaps — not once the light appears.

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

The day the light comes on, anywhere across City of Edinburgh, follow this routine.

- Pull in somewhere level, engine off, with time in hand — never rushing on the side of St Margaret's Road.

- Say "AdBlue" out loud as you unscrew the cap, once finding the AdBlue filler and reading it. Daft, perhaps, but it works.

- If both sit under one flap, check the diesel cap is still closed before you lift the bottle — and leave it on.

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

- Only after that, start the vehicle: close the cap, check once more, and make sure the diesel cap was never opened.

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

Leave out step five altogether.

## AdBlue in the diesel tank already, in Bruntsfield?

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

The fuel pump runs on many diesels as soon as the ignition goes on — and so leave it off.

Topping up with diesel won't weaken it: instead, AdBlue drops to the bottom of that tank, just where the fuel is taken from.

If you're at a forecourt, whether it is the JET or the BP, ask the staff to help roll the car away from the pump.

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

Where the motor has run by now, stop safely and switch the vehicle off.

Leave the M8 — under 5 miles out of Bruntsfield — at the first junction.

Tell us roughly how far it went: a run towards Edinburgh, under 3 miles away, is a bigger job than a short hop across Bruntsfield.

## Our arrival in Bruntsfield, and what takes place next

Our van reaches the car wherever it stopped — your own driveway, near St Margaret's Chapel, or by the local primary school.

The answers settle this work and our quote, so our technicians ask what got in, about how much, and if it's run.

No one heads out before you've heard the price over the phone.

Your system is then cleaned thoroughly, after that tank is cleared.

More than with petrol, it matters with AdBlue: the crystals build up, certain metals are attacked, and nothing clears out on its own, however long it sits.

Once your filter is flushed — or replaced, if needed — fresh diesel goes in, and finally your vehicle gets tested.

We do not leave until it has been started and is running properly.

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

No money in advance; you settle up on the day. At the end, a VAT invoice and the report from the engineer are handed to you for the insurer.

Wrong-fuel cover is included in plenty of insurance policies — so use the wait to check yours.
