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

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

Around Hough End, catching it before your motor turns usually leaves a drain and a thorough flush where it stands.

If you are reading before it has happened, the remainder of this page is about why it takes place and how to make sure it does not.

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

No single fluid but two: that's how many modern diesels near Hough End and Hough Side run, with diesel for the engine.

The exhaust, not the engine, is where AdBlue goes: sprayed into the fumes to fresh it, from a separate tank.

Separate tanks, separate fillers.

Under one flap, next to each other: that's the arrangement on many motors. Elsewhere, AdBlue's filler sits under the bonnet or in your boot instead.

At the petrol pump, the diesel side gets filled all the time.

Much less frequently, the AdBlue side is filled — mostly from a bottle, by a person working out where it goes.

The mistake lives in that gap.

## How does AdBlue in the diesel tank happen in Hough End?

Rarely is it carelessness: normally three things line up.

Haste follows from the warning. The vehicle 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 Pudsey Road, or heading home in the car park at Bramley Working Men's Club.

New-to-you vehicles come next, too. Hire cars, new motors and company vehicles put their fillers differently, and habit reaches for the cap it used on the old one.

Lastly, the spout goes in: diesel filler or AdBlue one, it goes in as readily, and after the tip starts, no part halts it.

Whether it happens in Park Spring or the middle of Hough End, it is the same few seconds.

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

Look at these before pouring, at a forecourt in Hough End or a drive out in New Scarbro. Seconds, that's all.

- Position misleads; the cap does not. AdBlue caps tend to be blue or bear the name "AdBlue" — diesel ones usually do not.

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

- The flap. Look inside the fuel flap for a label. Many cars say there which fuel goes where.

- In your boot or under the bonnet: that is where your filler is if it's not by the diesel cap, and the handbook tells you 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 outside Bramley (West Yorkshire).

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

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

- Turn off after you park — level ground, engine stopped, and not in a rush by Hough Tree Road on the verge.

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

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

- Tip slowly, using the bottle's own spout. Stop when it is full or when the bottle is empty.

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

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

Step five is out.

## Put AdBlue in the diesel tank around Hough End already?

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

Leave your ignition off too, because on plenty of diesels it alone starts the pump.

Filling up with diesel won't weaken it: rather than mixing, AdBlue drops to the bottom of that tank, right where the fuel is taken from.

If you are at a forecourt, whether it is the BP or the Morrisons, ask the staff to help roll your car away from the petrol pump.

At home around Hough End? So the car remains where it is.

Stop as soon as it is safe and switch off, if your engine has already run.

Leave the M621 — under 3 miles out of Hough End — at the next exit.

A short hop across Hough End is a smaller job than a run towards Leeds, under 5 miles away, and so tell us roughly how far it went.

## Our arrival around Hough End, and what takes place next

Our technicians come to your car wherever it has stopped, whether that's outside Greenhill Primary School, close to Bramley Lawn Day Centre or on your own driveway.

Which liquid got in, the quantity, and if it ran: our technicians ask because the replies decide both work and quote.

On the phone call itself, you are told the quote — ahead of dispatch.

Your system is then purged thoroughly, once your tank is cleared.

AdBlue crystallises and is corrosive to some of the metals in a fuel system, so it doesn't wash out on its own — which is why that counts more with AdBlue than with petrol.

A test comes at the end: before that, clean diesel goes in, and the filter is flushed or changed as needed.

We don't leave until it has been started and is running smoothly.

If your motor has not run, most jobs take about half an hour once we are there, using pumps that are fine on a busy forecourt and quiet enough to use outside a house at night.

You pay on the day, with nothing upfront, and get a VAT invoice and an engineer report for your insurer.

Before we get there, have a look at your insurance documents; many carry cover for misfuelling.
