# Why It Happens and How to Avoid It: AdBlue in a Diesel Tank in Swinford

AdBlue already in the diesel tank? Then set this page aside for now, keep the ignition and motor off, then call 0333 366 0103.

A drain plus a full flush, done right where your car stands in Swinford, is normally all it takes if caught before your engine runs.

The rest of this page explains why it occurs and how to make sure it doesn't — useful if you're reading before it has happened.

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

Not one fluid but two: that is what many modern diesels around Swinford and Shawell run, with diesel for your engine.

AdBlue's own tank holds it, and from there it goes to the exhaust, and there a spray treats the gas.

Different tanks, separate fillers.

On a lot of cars the two sit side by side under the same flap; on others the AdBlue filler is in the boot or under the bonnet.

Diesel goes in on each forecourt call-out, week in, week out.

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

That gap is where the error lives.

## Swinford: how AdBlue in your diesel tank occurs

Carelessness rarely explains it. What does is three things coming up at once.

To start with, the warning. Low AdBlue brings a message from the vehicle, and letting it run out leads to limp mode — hence a rushed top-up, perhaps before work off Chapel Fields, or at The Chequers Inn on the way home that evening.

Unfamiliar motors are next, too. Rentals, new cars and company vehicles place their fillers in new places, and habit goes for the cap used on the old one.

Lastly, the bottle goes in: diesel filler or AdBlue filler, it goes in just as easily, and once the tip begins, no part halts it.

Whether it takes place in Catthorpe or the middle of Swinford, it's the same few seconds.

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

A few seconds is all the checks take — so run through them before you pour anything, on a drive in Clay Coton or a forecourt in Swinford.

- Colour and lettering: an AdBlue cap is regularly blue, or says "AdBlue", where a diesel cap usually doesn't. Go by the cap, not its position.

- Plenty of motors fit AdBlue the smaller filler of the two.

- The flap. Look inside your fuel flap for a label. Plenty of motors say there which fuel goes where.

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

- Ask the person who drove it last — before you leave, not when the light comes on — when you pick up a hire or company car from somewhere like the car park at Rugby.

## Topping up AdBlue without it reaching the diesel tank

Wherever around Leicestershire the light comes on, this is a routine for the day.

- Stop on level, engine off, with time to spare — not hurried on the side of Glenview Close.

- Locate the AdBlue filler, check the cap, and say the name "AdBlue" aloud while unscrewing it. It seems daft. It works.

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

- Stop once the tank fills or the bottle is empty; until then, pour gently using the own spout.

- Only then, start your car: close the cap, check a second time, and make sure your diesel cap was never opened.

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

Stage five stays out.

## Swinford: already put AdBlue in your diesel tank?

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

The fuel pump runs on many diesels the moment your ignition is switched on — and so keep it off.

Filling up with diesel won't weaken it: instead, AdBlue sinks to the bottom of the tank, right where the fuel is taken from.

If you're on a forecourt, whether it is the Eddie Stobart Truckstop - Rugby or the Gulf, ask the staff to help push the vehicle away from the pump.

If you are on your own driveway in Swinford, leave the car where it is.

If your motor has already run, stop as soon as it is safe and switch off.

Swinford lies under a mile from the M6; on it, take the next junction.

Tell us roughly how far it went: a run towards Coventry, under 15 miles away, is a bigger job than a short hop across Swinford.

## Our arrival around Swinford, and what happens next

By Swinford Church of England Primary School, close to Swinford Village Hall or on your own driveway: wherever your car has stopped, we come to it.

Those answers settle this work and our price, so our technicians ask what was put in, roughly how much, and if it's run.

Nobody heads out before you've had our quote by phone.

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

Much more than with petrol, it counts here: the crystals form, certain metals are attacked, and none of that washes out on its own, however long it is left.

A test comes at the end: before that, clean diesel goes in, and the fuel filter is flushed or replaced as needed.

Before we go, our technicians fire it up and confirm that it's running smoothly.

Unstarted vehicles mostly mean a half-hour visit from arrival. The equipment is fine on a busy filling station, and hushed enough for a residential street late at night.

You pay on the day, with nothing upfront, and get a VAT invoice and an engineer report for your insurer.

It's worth checking your insurance while we travel to you: misfuelling cover comes with many policies.

## AdBlue drains in Swinford and across Leicestershire

Stanford on Avon and Lilbourne are among the towns near Swinford, a rural village, that the same vans cover, over LE postcodes.

Give a postcode beginning LE17 6, and the van arrives quickest.

Shifting your car isn't needed.

The drain takes place right there, whether a drive, a street near All Saints, or a lay-by on the way to South Kilworth Recreation Ground.

Ring and ask rather than assuming if you are near a boundary, or somewhere hard to explain, like the back of Straumēni.

## In short, for Swinford motorists

Always, the cap; then, the pour.

Petrol in Diesel drains it where it stands, anywhere across Leicestershire, if AdBlue has gone in your diesel tank anyway — so leave the car off and call 0333 366 0103.
