# Avoiding AdBlue in a Diesel Tank in Gnosall Heath: Why It Happens

Stop reading for a moment when the diesel tank already holds AdBlue in it: ignition off, motor off, then call 0333 366 0103.

A drain and a full flush, carried out just where your car stands in Gnosall Heath, is normally what it takes if found before the motor runs.

Here in advance? Then what follows covers how it comes about and what to stop it happening at all.

## Two fillers, two tanks: AdBlue in a diesel motor

Many modern diesels around Hollies Common, like those in Gnosall Heath, carry on two liquids; your engine gets only the diesel.

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

There's a filler on every tank.

Plenty of cars have a single flap for both, whereas some put the AdBlue filler to your boot or under the bonnet.

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

Much less frequently, the AdBlue side is filled — normally from a bottle, by a person working out where it goes.

Mistakes happen in the gap between the two.

## Gnosall Heath: how AdBlue in your diesel tank happens

It is seldom carelessness. Three things tend to line up.

Haste follows from the warning. Your car warns you as AdBlue runs low, and a dry tank puts it into limp mode — so the top-up gets done quickly, before work on a driveway off Ginger Hill, or heading home in the car park outside The Royal Oak.

Then the vehicle is new. A hire car, a new vehicle or a company car puts the fillers where your last one didn't, and your hand reaches for the cap it would have used on the old one.

A spouted bottle finds no obstacle at a diesel filler any more than at an AdBlue one. So the tip, once begun, carries on.

It's seconds, be it in Gnosall or bang in the heart of Gnosall Heath.

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

Look at these before pouring, at a forecourt in Gnosall Heath or a driveway over in Coton. Seconds, no more.

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

- Look at the size: the smaller filler neck is, on plenty of vehicles, the AdBlue one.

- A label inside your fuel flap frequently says which fuel goes where, on plenty of vehicles. Check for it.

- The handbook says where it lives when the filler is not next to your diesel cap: the boot, or under the bonnet.

- Whoever had it before knows. Ask when you collect a hire car or company car — at Stafford's car park, perhaps — rather than once the light appears.

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

A routine for the day the light comes on, wherever around Staffordshire that is.

- Stop on level, engine off, with time in hand — never hurried on the side of The Rank.

- Silly as it sounds, saying "AdBlue" out loud while you unscrew the cap works — once you have found the filler and read the cap.

- Both under one flap? Then confirm the lid on your diesel filler is still closed before lifting the bottle.

- Finish once that tank is topped up or the bottle runs dry; before that, tip gently through the built-in spout.

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

Stop there if you find, at step two or three, that you've already poured into your diesel side.

Step five is off limits.

## Put AdBlue in the diesel tank in Gnosall Heath already?

What follows is a short order of things, starting with not starting your motor.

Do not switch your ignition on; on many diesels that alone runs the fuel pump.

Don't top up with diesel to dilute it: AdBlue does not mix with diesel, it sinks to the bottom of your tank, where the fuel is drawn from.

On a forecourt — BP, another forecourt nearby or any other — the staff will normally help push the vehicle away, when you ask.

If you're on your own driveway in Gnosall Heath, leave the car where it is.

If your engine has already run, stop as soon as it is safe then switch off.

The next junction is the place to leave when you're on the M6, under 5 miles from Gnosall Heath.

A short hop across Gnosall Heath is a smaller job than a run towards Wolverhampton, under 15 miles away, so tell us roughly how far it went.

## Our arrival around Gnosall Heath, and what occurs next

By Gnosall St Lawrence Coe Primary Academy, close to Gnosall Methodist Church or on your own driveway: wherever your car has stopped, our technicians come to it.

Those replies decide the work and our quote, and so our engineers ask what went in, about how much, and if it has run.

You hear that quote on the phone, before anybody heads out.

After that: draining, then a thorough flush of the whole system.

AdBlue crystallises and is corrosive to some of the metals in a fuel system, so it does not wash out on its own — which is why that matters more here than with petrol.

A test is last: before that, fresh diesel goes in, and your filter is flushed or changed if necessary.

Then our technicians start the car and check it runs correctly before leaving.

If your engine hasn't run, the majority of jobs take about half an hour once we're there, using pumps that are safe on a working forecourt and quiet enough to use outside a house after dark.

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

It is worth checking your policy as the van travels to you: misfuelling cover comes with many policies.
