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

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

A drain plus a full flush, carried out just where your car sits in Stebbing, is usually what it takes when found before your motor runs.

Not happened yet? Further down, the page covers the reasons it takes place and the ways to avoid it altogether.

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

Plenty of modern diesels around Duck End, like those in Stebbing, carry on two fluids; the engine takes just the diesel.

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

Every tank comes with a filler of its own.

Under one flap, next to each other: that's the arrangement on a lot of vehicles. On others, AdBlue's filler is under the bonnet or in the boot instead.

The diesel side is fuelled at the petrol pump all the time.

Seldom topped up, AdBlue normally comes from a bottle, poured by a driver who must stop and think what cap it needs.

That gap is where the mistake lives.

## AdBlue in your diesel tank in Stebbing: how it happens

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

Hurry comes from the warning. The car tells you as AdBlue runs low, and an empty tank sends it into limp mode — so the top-up gets done in a rush, before work on a drive off Mill Lane, or on the way home in the car park at White Hart.

Next, the hand reaches for the cap it knew on the old motor — since a hire car, a new vehicle or a company car places the fillers somewhere your last one didn't.

No part stops the pour after it has started, because a bottle with a spout goes into a diesel filler as easily as an AdBlue one. The bottle fits.

Church End or the middle of Stebbing: it is the same few seconds either way.

## The AdBlue filler and your diesel filler: telling them apart

Check these first, on a forecourt around Stebbing or a driveway over in Stebbing Green. A few seconds, no more.

- The cap. The AdBlue cap is regularly blue, or marked "AdBlue". The diesel cap normally isn't. Read it instead of going by where it sits.

- On plenty of vehicles, the size tells: AdBlue has the smaller filler neck.

- Check inside your fuel flap: many vehicles carry a label there showing which fuel goes where.

- The handbook. If your filler is not by the diesel cap, it is in the boot or under the bonnet, and the handbook says which.

- Collecting a hire or company car, perhaps at the car park at Braintree? Ask the person who drove it last before you set off, not when the light goes on.

## Topping up AdBlue without it reaching the diesel tank

Anywhere in Essex the light comes on, this is a routine for the day.

- Not in a rush on the side of High Street, not on a slope, not with the motor running: park then switch off properly.

- Say "AdBlue" out loud as you unscrew the cap, once you find the AdBlue filler and read it. Daft, perhaps, but it works.

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

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

- Close the cap, then look again — making sure your diesel filler remained shut the whole time. Only then, start your car.

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

Never go on to stage five.

## Put AdBlue in the diesel tank around Stebbing already?

Brief list, then. Top of it: the engine stays off.

On plenty of diesels the ignition alone runs the fuel pump, and so do not switch the vehicle on.

Diluting it with more diesel fails, since AdBlue settles to the base rather than blending — and that's where the fuel is sucked from.

The attendants at Gulf, Tesco or any forecourt will usually lend a hand pushing your car clear if you ask.

Your own drive around Stebbing is the place it stays.

Already run? Stop when it is safe, then switch off.

Come off the M11 — under 10 miles out of Stebbing — at the next junction.

Tell us about how far it went: a run towards Chelmsford, under 15 miles away, is a bigger job than a short hop across Stebbing.

## What happens when our technicians get there in Stebbing

Our technicians come to your car wherever it has stopped, whether that's outside Stebbing Primary School, close to The Mount or on your own drive.

Our technicians ask what went in, about how much, and if it has run, since the replies determine the work and our quote.

On the call itself, you are told our price — before anything else.

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

More than with petrol, it matters with AdBlue: the crystals build up, certain metals are attacked, and none of it washes away on its own, no matter how long it sits.

The fuel filter is flushed, or replaced where it needs to be; fresh diesel goes in; and the car is tested.

Before we go, our technicians fire it up and check that it is running properly.

Most jobs are finished in about half an hour once we get there, as long as your engine hasn't run — and the pumps our technicians use are safe on a busy forecourt and quiet at night beside a house.

Payment happens on the day, not upfront, and you receive the documents your insurer wants: an engineer report and a VAT invoice.

Before we get there, take a look at your policy; plenty include cover for misfuelling.

## Stebbing and Essex: AdBlue drains across the area

Throughout CM postcodes, the vans covering Stebbing — a village — work the surrounding places too, Brookend and Bran End included.

A postcode starting CM6 3 gets the van to you fastest.

The vehicle remains put.

Draining takes place on the spot, whether a driveway, a road near St Mary the Virgin, Stebbing, or a lay-by on the way to Stebbing Bowls Club.

Assuming won't help behind St Mary the Virgin, Little Dunmow, on a boundary, or somewhere hard to describe; ring and ask.

## In short, for Stebbing people

Tip nothing until you have read the cap.

If AdBlue has gone in your diesel tank anyway, leave the car off then phone 0333 366 0103. Petrol in Diesel drains it where it stands, anywhere in Essex.
