# Why It Occurs and How to Prevent It: AdBlue in a Diesel Tank in Moorthorpe

Stop reading for a moment if your diesel tank already has AdBlue in it: ignition off, motor off, and call 0333 366 0103.

In Moorthorpe, catching it before your motor runs usually leaves a drain and a full flush where it stands.

Here before the event? Then what follows covers how it comes about and how to prevent it ever happening.

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

Diesel goes to your motor — but plenty of newer diesels driven round Moorthorpe and Priory Estate hold another fluid as well.

AdBlue's own tank keeps it, and from there it is sent to your exhaust, where spraying cleans the gas.

Each tank has its own filler.

Under one flap, side by side: that's the layout on a lot of cars. On others, AdBlue's filler is beneath the bonnet or in the boot instead.

At the petrol pump, your diesel side is topped up constantly.

Far less commonly, the AdBlue side is filled — normally from a bottle, by someone thinking about where it goes.

The mistake lives in that gap.

## How AdBlue in your diesel tank takes place around Moorthorpe

It is hardly ever carelessness. Three things tend to line up.

The warning comes first. As AdBlue runs low the car tells you, and if it runs out altogether, the car goes into limp mode. So the top-up is done in a hurry: on a driveway off Cambridge Street before work, or in the car park outside Moorthorpe Empire Working Mens Club on the way home.

Unfamiliar vehicles come next, as well. Rentals, new cars and company motors place their fillers differently, and the hand goes for the cap used on the old one.

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

It takes seconds, be it in Elm Estate or bang in the centre of Moorthorpe.

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

Check these before pouring, on a forecourt around Moorthorpe or a driveway out in Minsthorpe. A few seconds, no more.

- The cap. The AdBlue cap is regularly blue, or marked "AdBlue". Your diesel cap normally is not. Read it rather than going by position.

- Many motors give AdBlue the smaller filler of the two.

- Open the flap and look for a label — plenty of cars mark what goes in each inlet right there.

- In your boot or under the bonnet: that's where your filler is if it's not by the 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 the nearest station, ask before you leave, not when the light comes on.

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

The day the light comes on, anywhere in West Yorkshire, follow this routine.

- Not in a rush on the side of Harrow Street, not on a slope, not with your engine running: park then switch off first.

- Silly as it sounds, speaking "AdBlue" aloud as you unscrew the cap works — once you've found the filler and read it.

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

- Finish when the tank fills or the bottle is empty; until then, pour slowly using its built-in spout.

- Close the cap and check once more. Make sure the diesel cap was never opened. Only then start the car.

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

Don't go on to stage five.

## Put AdBlue in the diesel tank in Moorthorpe already?

Brief order, then. First: your engine stays unstarted.

Leave your ignition off too, because on plenty of diesels it by itself runs the pump.

Don't top up with diesel to dilute it: AdBlue doesn't mix with diesel, it sinks to the bottom of that tank, where the fuel is drawn from.

Ask the attendants to help push the vehicle away from the petrol pump if you are at a forecourt — the the nearest petrol station, the Shell or anywhere else.

Leave it where it is if you are on your own driveway around Moorthorpe.

Already run? Pull over once it is safe, then turn off.

Moorthorpe lies under 5 miles from the A1(M); on it, take the first exit.

Roughly how far did it go? Hopping across Moorthorpe is smaller work than a run of under 10 miles to Doncaster, so say.

## When our technicians turn up in Moorthorpe, what happens?

By St Joseph's Catholic Primary School, Moorthorpe, close to St Peter's and St Paul's Millenium Hall or on your own driveway: wherever your car has stopped, our engineers come to it.

We ask what got in, roughly how much, and whether it's run, since those answers settle the work and our price.

On the phone call itself, you hear our price — before anything else.

The fuel system is then rinsed thoroughly, once that tank is emptied.

With AdBlue that matters more than with petrol: it crystallises and is corrosive to some of the metals in a fuel system, and so it does not wash out on its own.

Once your filter has been cleaned — or renewed, where required — fresh diesel goes in, and finally your vehicle gets tested.

Next our technicians fire it up and confirm it runs smoothly before we leave.

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

No money upfront; you settle up that day. At the end, a VAT invoice and the report from the engineer are handed to you for your insurer.

Plenty of insurance policies include misfuelling cover, so it's worth checking yours whilst we are on the way.
