# How It Happens and How to Prevent It: AdBlue in a Diesel Tank in Huish Episcopi

Pause here a minute when the diesel tank already holds AdBlue in it: ignition off, engine off, then phone 0333 366 0103.

Caught before your engine runs, it's normally a drain and a thorough flush, done where your car is in Huish Episcopi.

The remainder of this page covers why it happens and how to make sure it does not — handy if you are reading ahead of time.

## Two fillers, two tanks: AdBlue in a diesel motor

Many modern diesels on the roads about Huish Episcopi and Wagg carry two liquids, not one. Diesel goes to your motor.

Kept in a tank of its own, AdBlue is sprayed into the exhaust stream to clean it.

Different tanks, different fillers.

On a lot of vehicles 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 pump, the diesel side gets filled all the time.

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

That gap is where the slip lives.

## AdBlue in the diesel tank around Huish Episcopi: how it happens

Three things tend to line up, and carelessness is seldom one of them.

First, the warning. Low AdBlue brings a message from the vehicle, and running out leads to limp mode — hence a hurried top-up, maybe before work off The Hill, or outside The Rose and Crown (Eli's) on the way home after work.

Unfamiliar motors are second, as well. Hire cars, new vehicles and company motors place their fillers differently, and the hand reaches for the cap used on the old one.

And the bottle fits. A bottle with a spout goes into a diesel filler as easily as an AdBlue one, and so nothing stops the tip after it has started.

Whether it takes place in Langport or the middle of Huish Episcopi, it's the same few seconds.

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

A couple of seconds is all these take — so check them before you tip anything, on a driveway in Garden City or a forecourt around Huish Episcopi.

- Read the cap instead of going by where it sits: AdBlue caps are regularly blue or marked "AdBlue", and diesel caps usually aren't.

- Check the size: the smaller filler neck is, on plenty of motors, the AdBlue one.

- Look inside the fuel flap: plenty of motors carry a label there showing which fuel goes where.

- Can't see it next to your diesel inlet? Then check beneath the bonnet or in your boot — the handbook says which.

- Check with the person who drove it last — before you leave, not when the light comes on — when you collect a hire or company car from somewhere like the car park at Bridgwater.

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

On the day the warning appears — anywhere you are in Somerset — a simple routine to follow.

- Not in a rush on the side of Tanyard Lane, not on a slope, not with your motor running: park then switch off first.

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

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

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

- Shut the cap, and check once more — confirm the diesel filler stayed closed the whole time. After that, start the vehicle.

Stop there if you find, at stage two or three, that you have already poured into your diesel side.

Don't go on to step five.

## Already put AdBlue in your diesel tank in Huish Episcopi?

Then the order of things is short. Don't start your motor.

On many diesels the ignition alone runs the fuel pump, and so don't switch it on.

Topping up with diesel won't dilute it: rather than mixing, AdBlue drops to the base of the tank, right where fuel is taken from.

The staff at Esso, BP or any forecourt will normally lend a hand to push the vehicle clear when you ask.

At home in Huish Episcopi? Then your car remains where it is.

When the engine has been run by now, pull over safely then switch the vehicle off.

Come off the M5 — under 10 miles out of Huish Episcopi — at the first junction.

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

## Huish Episcopi: what takes place when our technicians turn up

Wherever the car has stopped, whether by Huish Episcopi Primary School, near St Mary's Church or at home, our van travels to it.

Our technicians ask what went in, about how much, and whether it has run, since those answers determine the work and the quote.

Nobody sets off before you have heard our quote over the phone.

The system is then purged thoroughly, after that tank is drained.

Much more than with petrol, it counts with AdBlue: crystals form, some metals corrode, and nothing washes away on its own, however long it sits.

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

Then our engineers fire it up and check it runs smoothly before we leave.

If your motor hasn't run, the majority of jobs take about half an hour once we are there, using pumps that are safe on a busy forecourt and quiet enough to use outside a house after dark.

The insurer will ask for the engineer's report and the VAT invoice, and both are yours at the end. Payment comes on the day, with no deposit.

Wrong-fuel cover is included in many insurance policies — so use the wait to look at yours.
