# How It Happens and How to Avoid It: AdBlue in a Diesel Tank in Upper Wyche

Stop reading a minute if your diesel tank already holds AdBlue in it: ignition off, motor off, and ring 0333 366 0103.

A drain and a full flush, done right where the vehicle stands around Upper Wyche, is normally all it takes if caught before the motor runs.

The rest of this page explains why it takes place and how to make sure it doesn't — handy if you are reading before it has happened.

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

Diesel goes to the motor — yet plenty of current diesels driven around Upper Wyche and Malvern Common carry another fluid as well.

Its own tank keeps it, and from there it is sent to the exhaust, where spraying treats the gas.

Each tank comes with one filler of its own.

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

Diesel gets filled at every forecourt visit, again and again.

Seldom filled, AdBlue usually comes from a bottle, tipped by someone who has to stop and think which filler to use.

It's in that gap that the slip happens.

## Upper Wyche: how AdBlue in your diesel tank occurs

Carelessness seldom causes it. Instead is three things coming up at once.

On a driveway off Old Wyche Road before work, or in the car park outside Wyche Inn heading home: that's where the rushed top-up takes place. What is the reason for the rush? As AdBlue gets low the car tells you, and if it's empty, limp mode kicks in.

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

A spouted bottle meets no resistance at a diesel filler no more than at an AdBlue one. And so the tip, after begun, carries on.

It's a few seconds, be it in Upper Colwall or right in the centre of Upper Wyche.

## Telling the AdBlue filler from your diesel filler

Check these first, on a forecourt in Upper Wyche or a drive out in Colwall Stone. Seconds, that's all.

- Position misleads; the cap doesn't. AdBlue ones tend to be blue or bear the word "AdBlue" — diesel caps normally do not.

- Look at the size: the smaller filler neck is, on many motors, the AdBlue one.

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

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

- The previous driver knows. Ask as you collect a rental or fleet car — at Colwall's car park, say — rather than when the warning appears.

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

On the day the light comes on — anywhere you are around Worcestershire — a simple routine to use.

- Park then switch off. Not on a slope, not with the motor running, and not in a rush on the side of West Malvern Road.

- Daft as it sounds, speaking "AdBlue" aloud while you unscrew the cap does the trick — once you have located your filler and read it.

- The diesel cap stays on. When both share a flap, confirm it is closed before lifting the bottle.

- Stop when the tank fills or the bottle runs dry; until then, pour gently using the built-in spout.

- Close the cap, and look once more — making sure the diesel filler remained shut the whole time. After that, start the car.

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

Never carry on to step five.

## Already put AdBlue in the diesel tank around Upper Wyche?

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

Leave the ignition off too, because on many diesels it by itself runs your pump.

Topping up with diesel will not weaken it: instead, AdBlue drops to the base of the tank, right where fuel is drawn from.

Ask the staff to help push your car clear of the petrol pump if you are at a forecourt — the Texaco, the Gulf or anywhere else.

At home around Upper Wyche? So the car stays put.

Already started? Pull over when it's sensible, then switch off.

The next junction means where to leave when you are on the M5, under 10 miles from Upper Wyche.

Mileage matters — a short hop across Upper Wyche is a smaller job than driving under 10 miles towards Worcester — so tell us roughly how far it went.

## What takes place when our technicians turn up around Upper Wyche

Our van comes to the vehicle anywhere it stopped — your own driveway, beside Wyche Free Church, or outside Malvern Wyche CofE Primary School.

Which fluid went in, the quantity, and if it ran: our technicians ask because the replies set the work and price.

On the phone call itself, you are told the quote — ahead of anything else.

Then that tank is cleared and your system flushed thoroughly.

With AdBlue that matters more than with petrol: it crystallises and is corrosive to some of the metals in a fuel system, and so it doesn't wash out on its own.

Testing comes last: before that, clean diesel goes in, and your filter is cleaned or changed as needed.

Your engine is started next and tested to confirm it runs correctly, all before our engineers leave.

Using pumps fine on a working forecourt and quiet enough for use outside a house at night, most jobs in which your motor hasn't run need roughly half an hour after our engineers arrive.

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

Misfuelling cover is included in many insurance policies — so use the wait to check yours.
