# Why It Occurs and How to Prevent It: AdBlue in a Diesel Tank in Pilley

Stop here a minute if the diesel tank already has AdBlue in it: ignition off, motor off, then phone 0333 366 0103.

Usually, when the engine hasn't turned, it is emptied and fully cleaned where the car sits around Pilley.

Not happened yet? Further down, the rest of the page explains the why it happens and the ways to prevent it for good.

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

Many modern diesels in Birdwell, like those in Pilley, run on two liquids; the motor gets only the diesel.

Stored in a tank of its own, AdBlue is fed into the exhaust stream and cleans it.

Each tank has its own filler.

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.

At the petrol pump, the diesel side gets filled constantly.

Seldom topped up, AdBlue usually goes in from a bottle, poured by someone who has to stop and think what filler it needs.

It's in the gap that the error happens.

## AdBlue in your diesel tank around Pilley: how it happens

Rarely is it carelessness: normally three things line up.

Haste follows from the warning. The car warns you as AdBlue runs low, and a dry tank puts the vehicle into limp mode — so the top-up gets done quickly, before work on a drive off Worsbrough View, or on the way home in the car park at The Cock.

The old car's cap is where your hand goes — yet a rental car, a new motor or a company car keeps the fillers somewhere else. That's the second factor: a new car.

Third, the spout goes in: diesel filler or AdBlue one, it slides in just as easily, and once the pour starts, no part stops it.

Whether it happens in Hermit Hill or the middle of Pilley, it is the same few seconds.

## How to tell the AdBlue filler from the diesel one

Check these before pouring, at a forecourt around Pilley or a driveway over in Bromley. A few seconds, that's all.

- Read the cap instead of going by where it sits: AdBlue ones are frequently blue or marked "AdBlue", and diesel ones normally are not.

- Many vehicles give AdBlue the smaller filler of the two.

- Open the filler flap and check for a label — plenty of vehicles mark what goes in which inlet just there.

- In the boot or under the bonnet: that's where the filler is if it is not by the diesel cap, and the handbook tells you which.

- Collecting a hire or company car, perhaps at the car park outside Elsecar? Ask the person who drove it last before you set off, rather than once the light comes on.

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

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

- Park then switch off. Not on a slope, not with your motor running, and not in a rush on the side of The Avenue.

- Daft as it sounds, saying "AdBlue" out loud while you unscrew the cap does the trick — after you have found the filler and read the cap.

- The diesel cap remains on. When the two sit under a flap, confirm it is shut before lifting the bottle.

- Using the bottle's own spout, pour slowly — and stop when it is full or the bottle is empty.

- Close the cap, and look again — making sure the diesel filler stayed shut throughout. Only then, start the car.

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

Stage five is out.

## AdBlue in your diesel tank already, in Pilley?

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

The fuel pump runs on plenty of diesels as soon as the ignition is switched on — so keep it off.

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

On a forecourt — Shell, BP or any other — the attendants will usually help roll your car away, if you ask.

Leave it where it is if you are on your own driveway around Pilley.

Already started? Stop when it's sensible, then turn off.

Pilley sits under a mile from the M1; on it, use the first junction.

Mileage matters — a quick hop across Pilley is a smaller job than heading under 10 miles towards Sheffield — so tell us roughly how far it went.

## What occurs when our technicians arrive around Pilley

Anywhere the vehicle came to rest, whether outside Tankersley St Peter's CofE (Aided) Primary School, beside Pilley Methodist Church or at home, the van travels to it.

Both the work and the price rest on three answers — which fluid, what amount, and if it has run — so our engineers ask.

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

Then your tank is cleared and the system purged thoroughly.

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

After the filter has been flushed — or renewed, if needed — fresh diesel is added, and finally the vehicle is tested.

We don't go until it has been started and is running correctly.

With pumps safe on a working forecourt and quiet enough for use outside a house at night, most jobs in which the engine hasn't run take roughly half an hour after our technicians are there.

Payment is on the day, not upfront, and you are given the paperwork your insurer asks for: an engineer report and a VAT invoice.

It is worth looking at your insurance as the van travels to you: misfuelling cover comes with plenty of policies.
