# Preventing AdBlue in a Diesel Tank in West Pilton: Why It Occurs

Keep the engine and ignition off and phone 0333 366 0103 now — the rest can wait when AdBlue is already in your diesel tank.

Usually, when the motor hasn't run, it is emptied and fully flushed where the car sits in West Pilton.

Nothing happened yet? Below, the rest of the page covers the reasons it takes place and the how to prevent it altogether.

## AdBlue in a diesel car, and its separate tank

Diesel feeds the engine — but many modern diesels seen around West Pilton and Pilton hold a second liquid too.

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

There's a filler for every tank.

Other motors keep the AdBlue filler in the boot or under the bonnet; a lot of others have both together behind one flap.

Diesel goes in at each filling station visit, week in, week out.

Much less frequently, the AdBlue side gets filled — normally from a bottle, by someone thinking about where it goes.

The mistake lives in that gap.

## West Pilton: how AdBlue in your diesel tank happens

Seldom is it carelessness: normally three things coincide.

On a driveway off Pennywell Road before work, or in the car park outside Ferry Boat Bar on the way home: that's where the hurried top-up takes place. Why the rush? As AdBlue gets low the car warns you, and if it is gone, limp mode follows.

The old car's cap is where the hand reaches — yet a hire car, a new vehicle or a company car keeps the fillers elsewhere. That's the second thing: an unfamiliar car.

A spout-topped bottle meets no obstacle at a diesel filler no more than at an AdBlue one. And so the pour, after begun, carries on.

Whether it takes place in Muirhouse or the middle of West Pilton, it is the same few seconds.

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

Be it a West Pilton forecourt or a driveway out in Granton, spend a few seconds on these before any is poured in.

- Colour and lettering: an AdBlue cap is regularly blue, or says "AdBlue", where a diesel cap normally doesn't. Trust the cap, not its position.

- Many cars give AdBlue the smaller neck of the two.

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

- Cannot find it beside your diesel inlet? In that case look below the bonnet or in the boot — the owner's manual says which.

- The previous driver knows. Check as you pick up a hire car or fleet car — at Haymarket's car park, perhaps — rather than once the light appears.

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

Wherever in City of Edinburgh the light comes on, this is a routine for that day.

- Switch off after you park — level ground, motor off, and never rushed by Pennywell Gardens on the verge.

- Daft as it sounds, saying "AdBlue" out loud while you unscrew the cap works — once you have located the filler and read the cap.

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

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

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

Stop there if you find, at step two or three, that you've already poured into the diesel side.

Leave out stage five altogether.

## AdBlue in the diesel tank already, around West Pilton?

Short order, then. Top of that: the motor stays off.

Don't switch your ignition on; on plenty of diesels that alone runs the fuel pump.

Diluting it with extra diesel fails, since AdBlue settles to the bottom rather than mixing — and that is where the fuel is drawn from.

Ask the attendants to help push the car clear of the petrol pump if you're at a forecourt — the Morrisons, the Shell or somewhere else.

Leave it where it is if you're on your own driveway in West Pilton.

Where the motor has been run by now, pull over safely then turn it off.

On the M8, under 5 miles from West Pilton, that means the next junction.

A short hop across West Pilton is a smaller job than a run towards Edinburgh, under 3 miles away, and so tell us about how far it went.

## When our engineers get there in West Pilton, what happens?

The van reaches your car wherever it has come to rest — your own drive, beside North Edinburgh Arts, or by the local primary school.

Which liquid got in, the quantity, and if it ran: our technicians ask since those answers set both work and price.

During the phone call itself, you are told our quote — ahead of anything else.

Then that tank is emptied and the system cleaned thoroughly.

AdBlue crystallises and is corrosive to some of the metals in a fuel system, so it does not wash out on its own — which is why the flush matters more here than with petrol.

Once the filter is flushed — or renewed, where required — fresh diesel is added, and then the car is tested.

The motor is fired up next and checked to confirm it runs smoothly, all before our technicians go.

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

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

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