# Gossops Green: How Does AdBlue End Up in a Diesel Tank, and How Do You Prevent It?

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

Caught before the engine runs, it is normally a drain and a thorough flush, done where the vehicle is around Gossops Green.

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

## AdBlue in a diesel car, and its separate tank

Diesel feeds the motor — yet many newer diesels driven round Gossops Green and Broadfield hold a second fluid as well.

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

There's a filler on every tank.

Many of motors share a single flap for both, whereas some move the AdBlue filler to the boot or under the bonnet.

The diesel side is filled at the petrol pump all the time.

Far less often, the AdBlue side gets filled — mostly from a bottle, by a person thinking about where it goes.

The error lives in that gap.

## How AdBlue in your diesel tank happens around Gossops Green

Rarely is it carelessness: normally three things line up.

Hurry follows from the warning. Your car warns you as AdBlue runs low, and a dry tank puts the vehicle into limp mode — so the top-up happens in a rush, before work on a drive off Woldhurstlea Close, or on the way home in the car park outside The Windmill.

Then the vehicle is strange. A hire car, a new car or a company car puts the fillers where your last one did not, and your hand gets to for the cap it would have used on the old one.

A spout-topped bottle meets no resistance at a diesel filler any more than at an AdBlue one. And so the pour, once started, keeps on.

Bewbush or the middle of Gossops Green: it takes the same few seconds either way.

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

A few seconds is all the checks take — so check them before you pour anything, on a drive in West Green or a forecourt around Gossops Green.

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

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

- A label inside your fuel flap frequently shows which fuel goes where, on many vehicles. Check for it.

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

- Ask the person who drove it last — before you leave, not when the light comes on — if you collect a hire or company car from somewhere like the car park outside Ifield.

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

Wherever across West Sussex the light comes on, here is a routine for the day.

- Turn off after you park — level ground, motor off, and not rushed by Kidborough Road on the verge.

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

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

- Stop once that tank is topped up or the bottle runs dry; before that, pour slowly through the built-in spout.

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

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

Stage five stays off limits.

## Put AdBlue in your diesel tank around Gossops Green already?

Then the order of things is short. Do not start the motor.

On plenty of diesels your ignition alone runs the fuel pump, and so don't switch the car on.

Topping up with diesel won't dilute it: rather than mixing, AdBlue sinks to the bottom of that tank, just where the fuel is drawn from.

On a forecourt — Shell, Esso or any other — the staff will usually help push the car away, if you ask.

At home in Gossops Green? Then your car stays put.

Stop as soon as it is safe and switch off, if the engine has already run.

On the M23, under 3 miles from Gossops Green, that means the next junction.

Distance counts — a quick hop across Gossops Green is a smaller job than driving under 25 miles towards Brighton and Hove — so say roughly how far it went.

## What happens when we get there around Gossops Green

Wherever the vehicle came to rest, be it outside Gossops Green Primary, beside Crawley Spiritualist Church & Healing Centre or on your own drive, the van comes to it.

What liquid got in, the amount, and if it ran: our technicians ask since the replies set the work and price.

During the call itself, you hear the price — ahead of anything else.

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

More than with petrol, it counts here: the crystals build up, some metals corrode, and nothing washes out unaided, however long it is left.

Once the filter is cleaned — or replaced, if needed — fresh diesel goes in, and then your vehicle is tested.

Your engine is started next and tested to be sure it runs correctly, all before our engineers head off.

Most jobs are finished in about half an hour once our technicians arrive, provided your motor hasn't run — and the pumps our engineers use are fine on a live forecourt and quiet at night beside a house.

The insurer will ask for the engineer's report and the VAT invoice, and both are yours once this job is done. Payment comes on the day, with no money upfront.

Plenty of insurance policies include misfuelling cover, so it's worth checking yours whilst we're on the way.
