# Why It Occurs and How to Avoid It: AdBlue in a Diesel Tank in Greenlees

If AdBlue is already in your diesel tank, stop reading for a moment: leave your motor and your ignition off then call 0333 366 0103.

Usually, if the engine hasn't run, it is drained and thoroughly purged where the car sits in Greenlees.

Reading before the event? In that case what follows covers why it comes about and how to stop it ever happening.

## Why does AdBlue in a diesel vehicle need its own filler?

Not one liquid but two: that is what many modern diesels around Greenlees and Cathkin run, with diesel feeding the motor.

AdBlue's own tank holds it, and from there it goes to the exhaust, and there spraying cleans the gas.

Separate tanks, different fillers.

Plenty of vehicles have a single flap for the two, while some put the AdBlue filler to the boot or under the bonnet.

At the pump, your diesel side is topped up constantly.

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

It is in the gap that the error lives.

## How AdBlue in the diesel tank takes place in Greenlees

It's hardly ever carelessness. Three things tend to line up.

The warning comes first. As AdBlue runs low your car tells you, and if it runs out altogether, the vehicle drops into limp mode. So the top-up is done in a hurry: on a driveway off B759 before work, or in the car park outside The Lawburn on the way home.

Then your car is strange. A hire car, a new vehicle 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, so nothing stops the tip once it has started.

It's a few seconds, be it in Whitlawburn or right in the centre of Greenlees.

## Telling the AdBlue filler from the diesel filler

Be it a Greenlees forecourt or a drive over in Cambuslang, spend a couple of seconds on these before any goes in.

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

- Plenty of vehicles fit AdBlue the smaller neck of the two.

- A label inside the fuel flap often says which fuel goes where, on many motors. Look for it.

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

- The previous driver knows. Ask when you pick up a hire car or fleet car — at Kirkhill's car park, perhaps — not once the warning appears.

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

Anywhere in South Lanarkshire the light comes on, this is a routine for that day.

- Not in a rush on the side of Wallace Wynd, not on a slope, not with the motor running: park then switch off properly.

- Find the AdBlue filler and read the cap. Say "AdBlue" out loud as you unscrew it. It sounds silly and it works.

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

- Finish when your tank is topped up or the bottle runs dry; until then, pour gently using its built-in spout.

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

Discover at the second or third step that AdBlue went into the wrong tank? That's where you stop.

Don't go on to stage five.

## Put AdBlue in your diesel tank in Greenlees already?

Do not start your motor: that is where the short order of things starts.

Keep your ignition off as well, since on plenty of diesels switching it on alone starts your pump.

Thinning it with more diesel fails, since AdBlue settles to the base rather than mixing — and that's where your fuel is drawn from.

Ask the attendants to help roll the car clear of the petrol pump if you're at a forecourt — the the nearest petrol station, the Morrisons or anywhere else.

At home in Greenlees? So your car remains put.

Where the engine has run already, pull over safely and turn the vehicle off.

Come off the M74 — under 3 miles out of Greenlees — at the next exit.

Tell us roughly how far it went: a run towards Glasgow, under 5 miles away, is a bigger job than a short hop across Greenlees.

## Our arrival around Greenlees, and what occurs next

Anywhere your car came to rest, whether by the local primary school, near Kirk Burn Motte or on your own drive, the van comes to it.

We ask what was put in, about how much, and if it has run, since the answers decide this work and our quote.

On the phone call itself, you hear our quote — before dispatch.

Then that tank is cleared and your system cleaned thoroughly.

More than with petrol, it matters here: crystals build up, some metals corrode, and nothing washes out on its own, no matter how long it is left.

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

We do not go until it has been fired up and is running properly.

Unstarted vehicles mostly mean a half-hour visit after the moment we arrive. The equipment is fine on a live filling station, and quiet enough for a residential street after dark.

Your insurer will ask for the engineer's report and the VAT invoice, and you get both once the job is done. Payment comes on the day, with no money upfront.

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

## AdBlue drains in Greenlees and across South Lanarkshire

As a village, Greenlees shares its vans nearby places — Vicarland, Springhall — all the way across G postcodes and the wider area beyond.

Give a postcode that starts G72 8, and our van arrives quickest.

The car stays where it is.

Wherever it stands — near Whitlawburn Community Resource Centre, in a layby en route to Holmhills Park, on a drive — that's where it is drained.

Awkward to pin down, like the back of Kirkhill Bowling Club? By a border? Checking is better than assuming, so ring.

## For Greenlees people, the short version

Always, the cap; then, the tip.

If AdBlue has gone in your diesel tank anyway, leave the car off then ring 0333 366 0103. Petrol in Diesel drains it where it waits, anywhere across South Lanarkshire.
