# Avoiding AdBlue in a Diesel Tank in Craigshill: Why It Occurs

Leave your motor and ignition off and ring 0333 366 0103 now — reading can wait when AdBlue is already in the diesel tank.

Normally, when the motor hasn't run, it's emptied and fully purged where your vehicle sits around Craigshill.

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

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

Many current diesels on the roads around Craigshill and Ladywell carry two liquids, not one. Diesel goes to your engine.

AdBlue goes to your exhaust, where it is sprayed into the gas to fresh it, and it lives in a tank of its own.

Each tank has its own filler.

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

The diesel side is topped up at the pump all the time.

The AdBlue side is topped up far less frequently, normally from a bottle, and normally by somebody who has to stop and think where it goes.

The slip lives in that gap.

## How AdBlue in your diesel tank takes place around Craigshill

Seldom is it carelessness: usually three things line up.

Haste comes from the warning. Your car warns you as AdBlue runs low, and an empty tank puts the vehicle into limp mode — so the top-up gets done in a rush, before work on a drive off Adelaide Street, or heading home in the car park outside The Tower.

The old car's filler is where the hand reaches — yet a rental car, a new car or a company car keeps the fillers somewhere else. That's a second factor: an unfamiliar motor.

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

The same few seconds decide it, in the middle of Craigshill or out in Howden.

## Telling the AdBlue filler from the diesel filler

Whether a Craigshill forecourt or a driveway over in Almondvale, spend a couple of seconds over these before anything goes in.

- Colour and marking: an AdBlue cap is often blue, or says "AdBlue", where a diesel cap usually doesn't. Trust the cap, not its position.

- Check the size: the smaller neck is, on plenty of cars, the AdBlue one.

- Open the flap and look for a label — plenty of motors mark what belongs in each filler right there.

- Can't see it beside your diesel filler? In that case check beneath the bonnet or inside your boot — the handbook will say which.

- The person who drove it last. On a hire or company car picked up from somewhere like the car park outside Uphall, ask before you leave, not when the light comes on.

## How to top up without AdBlue in your diesel tank

When the light goes on, wherever around West Lothian, follow this routine.

- Turn off once parked — level ground, motor off, and never in a rush by Fremantle Street on the verge.

- Say "AdBlue" out loud as you unscrew the cap, after you find the AdBlue filler and reading it. Silly, perhaps, but it works.

- The two under a single flap? Then make sure the cap on the diesel side stays shut ahead of lifting the bottle.

- Finish once your tank fills or the bottle is empty; until then, pour gently using its built-in spout.

- 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 stage that AdBlue went in the diesel tank? That is where you stop.

Do not go on to step five.

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

Brief list, then. Top of that: the motor remains unstarted.

Keep your ignition off as well, since on many diesels it alone runs the fuel pump.

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

On a forecourt — Shell, Asda or any other — the staff will normally help push your car away, when you ask.

On your own drive around Craigshill? Then the car remains where it is.

Already started? Pull over once it is safe, then turn off.

Craigshill lies under 3 miles from the M8; there, use the first exit.

About how far did it go? Hopping across Craigshill is less work than a run of under 15 miles towards Dunfermline, and so say.

## Our arrival around Craigshill, and what happens next

Our van reaches your car anywhere it stopped — your own drive, beside Almondbank Library, or outside the local primary school.

Our technicians ask what went in, about how much, and whether it's run, since those replies determine this work and our quote.

You get that quote on the phone, before anyone heads out.

Draining that tank comes next, followed by a thorough flush of the system.

Unlike petrol, AdBlue leaves crystals and attacks certain fuel-system metals, and none of it clears away by itself. That is why it matters more.

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

Before leaving, our engineers start it and make sure that it is running smoothly.

Unrun vehicles usually mean a half-hour visit after arrival. The equipment is safe on a busy filling station, and hushed enough for a driveway late at night.

Nothing in advance; you settle up that day. Afterwards, a VAT invoice and a report from the engineer are handed to you for your insurer.

Many insurance policies include misfuelling cover, so it's worth checking yours while we are on the way.

Quickest of all: give a EH54 5 postcode for our van.

No need to move your car.

A driveway, a lay-by on the way to Letham Park, a side street close to St. Andrew's R. C. Church: our technicians drain the car where it sits.

Guessing doesn't help behind Craigwillow Centre, close to a border, or anywhere awkward to pin down; phone and check.

## For Craigshill people, the short version

Tip nothing till you have read the cap.

Petrol in Diesel empties it where it stands, anywhere around West Lothian, if AdBlue has gone in the diesel tank regardless — so leave the car off then call 0333 366 0103.
