# Why It Happens and How to Prevent It: AdBlue in a Diesel Tank in Grange Villa

Leave the engine and ignition off then phone 0333 366 0103 first — reading can wait when AdBlue is already in the diesel tank.

In Grange Villa, catching it before your motor turns normally means draining and a thorough flush where it stands.

The remainder of this page explains why it takes place and how to make sure it does not — useful if you're reading before it has happened.

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

Diesel feeds the motor — yet many modern diesels driven around Grange Villa and Beamish carry another fluid too.

Kept in a tank of its own, AdBlue is fed into the exhaust gas and cleans it.

Different tanks, different fillers.

On a lot of cars the two sit side by side under the same flap; on others the AdBlue filler is in the boot or under the bonnet.

Topping up the diesel side at the pump happens constantly.

Rarely filled, AdBlue usually comes from a bottle, tipped by a driver who has to stop and think which cap it needs.

It is in the gap that the error happens.

## How AdBlue in the diesel tank takes place in Grange Villa

It is rarely carelessness. Three things tend to line up.

Hurry comes from the warning. The vehicle warns you as AdBlue runs low, and an empty tank puts it into limp mode — so the top-up happens in a rush, before work on a drive off Front Street, or heading home in the car park at The Moorings.

Then, the hand reaches for the cap it knew on the old car — because a hire car, a new vehicle or a company car puts the fillers where your last one didn't.

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

It's seconds, whether out in West Pelton or right in the heart of Grange Villa.

## Telling the AdBlue filler from the diesel filler

Before you pour anything, whether on a drive in Pelton Fell or a forecourt in Grange Villa, check these. They take a few seconds.

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

- Plenty of motors fit AdBlue the smaller neck of the two.

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

- The handbook. If the filler is not by your diesel cap, it is in the boot or under the bonnet, and the handbook says which.

- The person who drove the car last. On a hire or company car collected from somewhere like the car park at Chester-Le-Street, ask before you leave, not when the light comes on.

## Topping up AdBlue without it reaching the diesel tank

For the day the light appears — wherever it is around Durham — a routine to use.

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

- Daft as it sounds, saying "AdBlue" aloud while you unscrew the cap does the trick — once you have located your filler and read the cap.

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

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

- Before you start your car, shut the cap and check a second time that your diesel cap was never opened off.

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

Don't carry on to stage five.

## AdBlue in your diesel tank already, in Grange Villa?

Brief order, then. First: your motor stays off.

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

Do not top up with diesel to thin it: AdBlue doesn't mix with diesel, it sinks to the bottom of the tank, where the fuel is pulled from.

Ask the staff to help roll the vehicle away from the pump if you're at a forecourt — the Durham Fuel Centre, the Esso or somewhere else.

If you're on your own driveway around Grange Villa, leave the car where it stands.

When the motor has run already, stop safely then turn the vehicle off.

Come off the A1(M) — under 3 miles out of Grange Villa — at the next junction.

About how far did it go? Hopping across Grange Villa is less work than a run of under 10 miles to Durham, so say.

## What takes place when our engineers turn up around Grange Villa

Our technicians come to the car wherever it has stopped, whether that is outside West Pelton Primary School, near West Pelton Methodist Church or on your own drive.

The replies determine this work and the price, so our technicians ask what got in, about how much, and if it has run.

You hear that price on the phone, before anyone heads out.

After that: a drain, then a thorough flush of the whole system.

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

The filter flushed or, where it must be, replaced; fresh diesel in; then a test of your car.

The engine is fired up next and checked to confirm it runs correctly, all before we head off.

With pumps fine on a working forecourt and quiet enough for use outside a house at night, most jobs where the motor has not run take roughly half an hour after we arrive.

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

It is worth looking at your policy while we travel to you: misfuelling cover is included with many policies.
