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

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

Normally, when your motor has not run, it is drained and thoroughly cleaned where your car sits in Worsthorne.

Nothing happened yet? Further down, the page explains the why it happens and the how to prevent it altogether.

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

Diesel feeds the engine — but plenty of newer diesels seen round Worsthorne and Brunshaw carry another fluid too.

The exhaust, not your engine, is where AdBlue ends up: sprayed into the gas to fresh them, from a separate tank.

Separate tanks, different fillers.

Under one flap, side by side: that's the layout on many motors. Elsewhere, AdBlue's filler is under the bonnet or in the boot instead.

At the petrol pump, your diesel side gets filled all the time.

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

The mistake lives in that gap.

## AdBlue in the diesel tank in Worsthorne: how it happens

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

To start with, the warning. Low AdBlue triggers a message from the car, and running dry means limp mode — so a rushed top-up, perhaps before work off Raven Oak Lane, or outside The Bay Horse on the way home that evening.

New-to-you cars come next, too. Hire cars, new motors and company motors put their fillers in new places, and the hand goes for the cap used on the old one.

A spouted bottle meets no resistance at a diesel filler any more than at an AdBlue one. So the tip, after started, carries on.

It takes seconds, whether out in Brownside or right in the centre of Worsthorne.

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

A few seconds is all the checks take — so run through them before you tip anything, on a driveway in Mereclough or a forecourt around Worsthorne.

- Where it sits can mislead; the cap doesn't. AdBlue caps are often blue or carry the name "AdBlue" — diesel ones usually do not.

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

- Open the filler flap and check for a label — plenty of motors mark what goes in each filler right there.

- Can't find it beside your diesel filler? In that case check beneath the bonnet or inside your boot — the handbook says where.

- The person who drove the vehicle last. On a hire or company car collected from somewhere like the car park outside Burnley Central, ask before you leave, not when the light comes on.

## Topping up AdBlue without it reaching the diesel tank

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

- Park and switch off. Not on a slope, not with the engine running, and not in a rush on the side of Brownside Road.

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

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

- Slowly does it, through the bottle's own spout, till it is full or the bottle runs out.

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

Discover at the second or third stage that AdBlue went into the wrong filler? That is where you stop.

Never go on to stage five.

## Put AdBlue in your diesel tank around Worsthorne already?

Short list, then. First: the engine stays unstarted.

Keep the ignition off as well, because on plenty of diesels it alone runs the pump.

AdBlue doesn't mix with diesel — it sinks to the bottom of that tank, where your fuel is sucked from — so do not top up with diesel to thin it.

At a forecourt — Flogas, Monarch Garage or another — the attendants will usually help roll your car away, if you ask.

On your own drive in Worsthorne? So your car stays where it is.

When the engine has been run already, stop somewhere safe then turn the car off.

Come off the M65 — under 3 miles out of Worsthorne — at the first junction.

Tell us about how far it went: a run towards Bradford, under 25 miles away, is a bigger job than a short hop across Worsthorne.

## Our arrival in Worsthorne, and what takes place next

Our technicians come to your car wherever it has stopped, whether that's outside Worsthorne Primary School, close to St John the Evangelist or on your own driveway.

Which fluid went in, the amount, and if it ran: our technicians ask because those answers set both work and price.

Nobody sets off until you have heard our price over the phone.

The system is then flushed thoroughly, once that tank is drained.

Not like petrol, AdBlue leaves crystals and attacks some fuel-system metals, and neither washes away unaided. Hence it matters more.

The filter flushed or, if it must be, swapped; fresh diesel in; then a test of the vehicle.

Before we leave, our technicians start the engine and check that it is running smoothly.

If the engine has not run, most jobs take about half an hour once we are there, using pumps that are fine on a working forecourt and quiet enough to use outside a house at night.

Your insurer will ask for the engineer's report and your VAT invoice, and you get both at the end. Payment comes on the day, with no deposit.

Wrong-fuel cover is part of many insurance policies — and so use the wait to look at yours.

The car does not need to shift.

Anywhere it sits — beside Remains of stone circle, on a lay-by en route to Hag, on a drive — that is where it gets cleared.

Tricky to pin down, like the back of Brunshaw Methodist Church? By a county line? Asking beats guessing, so ring.
