# AdBlue in a Diesel Tank in Ditchampton: How It Happens and How to Stop It

Leave your engine and ignition off and call 0333 366 0103 first — reading can wait if AdBlue is already in your diesel tank.

Caught before the engine runs, it is normally a drain and a thorough flush, done where the car is around Ditchampton.

If you're reading before it has happened, the rest of this page is about why it happens and how to make sure it does not.

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

Many current diesels on the roads about Ditchampton and Bulbridge carry two liquids, not one. Diesel goes to your motor.

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

Each tank has its own filler.

Many of motors have a single flap for both, whereas others put the AdBlue filler to the boot or under the bonnet.

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

Seldom topped up, AdBlue normally goes in from a bottle, tipped by a driver who has to stop and think which filler it needs.

The mistake lives in that gap.

## How does AdBlue in the diesel tank happen around Ditchampton?

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

The warning comes first. As AdBlue runs low the car tells you, and if it runs out altogether, your vehicle goes into limp mode. So the top-up is done in a hurry: on a driveway off Philip Road before work, or in the car park at The Bear Inn on the way home.

The old car's cap is where your hand reaches — yet a hire car, a new car or a company car puts the fillers elsewhere. That's the second factor: a strange vehicle.

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

It takes a few seconds, be it in Ugford or bang in the heart of Ditchampton.

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

Look at these first, on a forecourt in Ditchampton or a driveway over in North Burcombe. A few seconds, no more.

- Blue and marking: an AdBlue cap is regularly blue, or says "AdBlue", where a diesel cap normally does not. Trust the cap, not its position.

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

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

- In the boot or under the bonnet: that is where your filler is if it is not by your diesel cap, and the handbook says which.

- The person who drove the vehicle last. On a hire or company car picked up from somewhere like the car park at Salisbury, ask before you leave, not when the light comes on.

## How to top up without AdBlue in the diesel tank

A routine for the day the light comes on, wherever across Wiltshire that is.

- Stop on level, motor off, with time to spare — never rushing on the side of Wishford Road.

- Silly as it sounds, saying "AdBlue" out loud while you unscrew the cap works — after you've located your filler and read it.

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

- Stop when that tank fills or the bottle is empty; until then, pour slowly using its own spout.

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

Find during the second or third step that the bottle went into the wrong tank? That's where you stop.

Skip step five entirely.

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

What follows is a short order of things, beginning with no starting the engine.

Do not switch the ignition on; on many diesels that alone runs the fuel pump.

Filling up with diesel will not weaken it: rather than mixing, AdBlue sinks to the base of your tank, just where the fuel is taken from.

On a forecourt — Shell, Texaco or another — the attendants will normally help roll your car away, if you ask.

On your own drive around Ditchampton? So your car stays put.

Already run? Stop once it's sensible, then switch off.

The next junction is where to leave if you are on the M27, under 25 miles from Ditchampton.

Tell us about how far it went: a run towards Salisbury, under 5 miles away, is a bigger job than a short hop across Ditchampton.

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

Outside Wilton CofE Primary School, near St Mary & St Nicholas or on your own drive: wherever the car has stopped, our technicians come to it.

What fluid went in, the quantity, and if it ran: our technicians ask since the replies set both work and quote.

The quote is given over the phone, ahead of any van leaving.

Then that tank is emptied and the system flushed thoroughly.

Much more than with petrol, it matters with AdBlue: crystals form, some metals are attacked, and none of that clears away unaided, however long it sits.

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

The engine is fired up next and tested to confirm it runs smoothly, all before our technicians leave.

Unrun vehicles usually mean a half-hour visit from the moment we arrive. The equipment is safe on a live filling station, and hushed enough for a residential street late at night.

Paying is on the day, not upfront, and you are given the documents your insurer wants: an engineer report and a VAT invoice.

While we travel, take a look at your policy; many include cover for misfuelling.

Tricky to pin down, like the back of Michael Herbert Hall? By a county line? Checking is better than guessing, so ring.
