# Preventing AdBlue in a Diesel Tank in Vicarage Row: Why It Happens

Stop here for a moment if your diesel tank already holds AdBlue in it: ignition off, motor off, then ring 0333 366 0103.

A drain plus a full flush, done right where the car stands around Vicarage Row, is normally all it takes when caught before the motor runs.

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

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

Diesel goes to the engine — yet many current diesels driven round Vicarage Row and Tipner carry another fluid too.

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

Different tanks, different fillers.

Other cars keep the AdBlue filler in the boot or under the bonnet; a lot more place both side by side under one flap.

Diesel gets filled at every forecourt call-out, week in, week out.

The AdBlue side is fuelled far less commonly, usually from a bottle, and usually by somebody who has to stop and think where it goes.

That gap is where the error lives.

## AdBlue in your diesel tank in Vicarage Row: how it happens

Carelessness rarely causes it. Instead is three things coming up together.

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

Next, the hand reaches for the cap it knew on the old motor — because a hire car, a new motor or a company car places the fillers where your last one did not.

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

It takes a few seconds, whether in St Francis Court or bang in the centre of Vicarage Row.

## Which filler is for AdBlue, and which for diesel?

Whether a Vicarage Row forecourt or a driveway over in North End, take a few seconds on these before anything is poured in.

- Blue and lettering: an AdBlue cap is often blue, or says "AdBlue", where a diesel cap usually does not. Go by the cap, not its position.

- The size. On plenty of cars the AdBlue filler neck is the smaller of the two.

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

- Cannot find it beside your diesel inlet? Then check below the bonnet or in your boot — the owner's manual says which.

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

## Keeping AdBlue out of the diesel tank when you top up

The day the light comes on, wherever around Hampshire, use this routine.

- Turn off after you park — flat ground, motor off, and not rushed beside Phoenix Square on the verge.

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

- The diesel cap stays on. Where both sit under a flap, make sure it's closed before lifting the bottle.

- Gently is best, through the bottle's own spout, until it is full or the bottle runs out.

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

Spot at stage two or three that it's already gone into your diesel side? Then stop just there.

Never go on to stage five.

## Already put AdBlue in your diesel tank around Vicarage Row?

Don't start your engine: that's where the short order of things starts.

The fuel pump runs on plenty of diesels as soon as the ignition goes on — so leave it off.

AdBlue does not mix with diesel — it sinks to the bottom of your tank, where the fuel is sucked from — so do not top up with diesel to dilute it.

The staff at Shell, Esso or any forecourt will normally lend a hand pushing the car clear if you ask.

If you're on your own drive around Vicarage Row, leave the vehicle where it stands.

When the motor has been run by now, stop somewhere safe then switch the car off.

The next exit means the place to come off if you're on the M27, under a mile from Vicarage Row.

A short hop across Vicarage Row is a smaller job than a run towards Portsmouth, under 3 miles away, so tell us roughly how far it went.

## What takes place when our technicians turn up in Vicarage Row

We come to the vehicle wherever it has stopped, whether that is outside King's Academy Northern Parade (Junior), near St Francis' Church or on your own driveway.

What fluid was put in, the quantity, and whether it ran: we ask since the replies decide the work and price.

You get that price by phone, before anybody sets off.

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

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

After the filter is cleaned — or replaced, where required — fresh diesel is added, and finally the vehicle gets tested.

Next we fire it up and confirm it runs smoothly before we go.

Unrun vehicles usually mean a half-hour visit after the moment we arrive. The kit is safe on a busy filling station, and hushed enough for a residential street after dark.

The insurer will ask for the engineer's report and the VAT invoice, and you get both at the end. Payment is on the day, with no money upfront.

While we travel, have a look at your policy; many carry cover for misfuelling.

## About Vicarage Row and where it is

Vicarage Row is a coastal locality in Hampshire, situated near the city of Portsmouth and close to the neighbouring areas of St Francis Court and Hilsea. Vicarage Row lies at a low elevation of around 2 metres, reflecting its proximity to the sea. Vicarage Row is characterized by predominantly flat-type housing, which is common in many coastal areas of southern England.

## AdBlue drains across Hampshire, Vicarage Row included

Over PO postcodes, our vans that cover Vicarage Row — a coastal area — work the surrounding places too, Highbury and Hilsea among them.

Fastest of all: give a PO2 9 postcode to our van.

The car does not need to shift.

The drain happens right there, be it a driveway, a road near Howard Road Community Centre, or a layby towards Portsmouth Grammar School Playing Fields.

If you are close to a border, or somewhere hard to describe like the back of Bastion 1 Hilsea Lines, ring and ask instead of guessing.

## In short, for Vicarage Row drivers

Tip no AdBlue until you've read the cap.

Still AdBlue in the diesel tank? Petrol in Diesel will empty it wherever it is, wherever in Hampshire: keep the car off and ring 0333 366 0103.
