# Avoiding AdBlue in a Diesel Tank in Lane Head: Why It Happens

AdBlue already in your diesel tank? In that case put this page down a moment, keep the ignition and engine off, then ring 0333 366 0103.

Usually, if the engine hasn't turned, it's emptied and fully cleaned where the car sits in Lane Head.

Reading before the event? In that case the rest explains how it comes about and how to prevent it ever happening.

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

Diesel feeds your motor — yet plenty of modern diesels driven about Lane Head and Huttock Top hold another liquid too.

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

There is a filler on each tank.

Some vehicles put the AdBlue filler in the boot or under the bonnet; plenty of others have the two side by side under one flap.

The diesel side is filled at the pump all the time.

The AdBlue side is filled far less commonly, usually from a bottle, and normally by someone who has to stop and think where it goes.

The mistake lives in that gap.

## How does AdBlue in your diesel tank happen around Lane Head?

Rarely is it carelessness: usually three things line up.

The warning comes first. As AdBlue runs low your 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 South Street before work, or in the car park outside the pub in the village on the way home.

Next, your hand goes for the cap it would have used on the old vehicle — since a hire car, a new motor or a company car puts the fillers where your last one didn't.

Third, the spout fits: a diesel filler or AdBlue one, it slides in as easily, and once the tip starts, no part stops it.

The same few seconds decide it, in the middle of Lane Head or out in Bacup.

## Which filler is for AdBlue, and which for diesel?

Look at these first, on a forecourt around Lane Head or a driveway over in Higher Change. A few seconds, no more.

- The cap. The AdBlue cap is commonly blue, or marked "AdBlue". Your diesel cap normally is not. Read it instead of going by where it sits.

- The size. On plenty of cars the AdBlue filler neck is the smaller of the two.

- Open the filler flap and check for a label — many vehicles mark what goes in which inlet just there.

- 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.

- Collecting a hire or company car, perhaps at the car park at Walsden? Check with whoever drove the vehicle last before you set off, not once the light comes on.

## AdBlue top-ups that never reach the diesel tank

Anywhere across Lancashire the light comes on, here is a routine for that day.

- Park then switch off. Not on a slope, not with the motor running, and not in a rush on the side of Venture Street.

- Say "AdBlue" out loud as you unscrew the cap, after you find the AdBlue filler and read it. Silly, yes, yet it does the trick.

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

- Using the bottle's own spout, pour slowly — and stop when it is full or the bottle is empty.

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

Spot at step two or three that it has already gone into the diesel side? Then stop just there.

Stage five stays off limits.

## AdBlue in the diesel tank already, around Lane Head?

Don't start the motor: that is where the short order of things starts.

The fuel pump runs on plenty of diesels the moment the ignition goes on — so leave it off.

Diluting it with extra diesel fails, because AdBlue sinks to the base rather than blending — and that is where your fuel is sucked from.

The attendants at Texaco, Shell or another forecourt will usually lend a hand pushing the car clear if you ask.

Your own driveway around Lane Head is where it should stay.

When your engine has run by now, stop somewhere safe and turn the car off.

On the M66, under 10 miles from Lane Head, that means the next exit.

Mileage counts — a short hop across Lane Head is a smaller job than heading under 25 miles to Manchester — so say about how far it went.

## When we arrive around Lane Head, what happens?

Wherever the car has stopped, be it outside Bacup Thorn Primary School, near Bacup Christ Church or at home, our van travels to it.

We ask what was put in, roughly how much, and if it's run, since those replies settle this work and the quote.

No one sets off until you have had our price by phone.

Emptying your tank comes next, then a full flush of the fuel system.

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 with AdBlue than with petrol.

After your filter has been cleaned — or replaced, where required — fresh diesel goes in, and finally your vehicle is tested.

Next our engineers start the engine and confirm it runs properly before we leave.

Unrun cars mostly mean a half-hour job after the moment we arrive. The equipment is fine on a live forecourt, and quiet enough for a driveway late at night.

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

It's worth looking at your insurance as the van travels to you: misfuelling cover is included with plenty of policies.
