Two fillers, two tanks: AdBlue in a diesel vehicle

Many modern diesels around Nether Kellet, like those in Bolton Town End, carry on two fluids; your motor takes only the diesel. Kept in a tank of its own, AdBlue is sprayed into your exhaust gas to clean it.

There's a filler on each tank. On a lot of motors the two sit side by side under the same flap; on others the AdBlue filler is in your boot or under the bonnet. Diesel gets filled at each forecourt call-out, again and again. The AdBlue side is topped up far less regularly, usually from a bottle, and normally by someone who has to stop and think where it goes. The mistake grows in the gap between them.

How does AdBlue in the diesel tank take place in Bolton Town End?

Three things tend to line up, and carelessness is rarely one of them.

First, the warning. Low AdBlue triggers a message from the car, and letting it run dry means limp mode — so a rushed top-up, perhaps before work off Bye-Pass Road, or outside The Blue Anchor on the way home after work.

Unfamiliar motors are second, as well. Hire cars, new motors and company motors place their fillers in new places, and the hand reaches for the cap it used on the old one.

No part stops the tip once it has started, because a bottle with a spout goes into a diesel filler as readily as an AdBlue one. The bottle fits. It's a few seconds, be it in Bolton-le-Sands or bang in the heart of Bolton Town End.

How to tell the AdBlue filler from the diesel one

A few seconds is all the checks take — so run through them before you pour anything, on a driveway in Crag Bank or a forecourt in Bolton Town End.

  • Blue and lettering: an AdBlue cap is frequently blue, or says "AdBlue", where a diesel cap usually does not. Trust the cap, not its position.
  • Check the size: the smaller neck is, on plenty of vehicles, the AdBlue one.
  • Lift the flap and check for a label — plenty of vehicles mark which belongs in which inlet just there.
  • In the boot or under the bonnet: that's where your filler sits if it is not by the diesel cap, and the handbook tells you which.
  • The previous driver will know. Ask when you pick up a hire car or company car — from Carnforth's car park, perhaps — not once the light comes on.

AdBlue top-ups that never reach your diesel tank

A routine for the day the light comes on, wherever in Lancashire that is.

  • Stop somewhere level, engine off, with time to spare — not hurried on the side of Grange View.
  • Locate the AdBlue filler, read the cap, and say the word "AdBlue" out loud as unscrewing it. It sounds silly. It works.
  • The diesel cap remains on. Where both sit under a flap, make sure it is shut before lifting the bottle.
  • Stop when the tank is topped up or the bottle is empty; before that, tip gently using the own spout.
  • Close the cap and check again. Make sure the diesel cap was never opened. Only then start your car.

Discover at the second or third step that the bottle went into the wrong tank? That's where you stop. Step five is out.

Bolton Town End: already put AdBlue in your diesel tank?

Brief order, then. Top of it: the motor stays unstarted. The fuel pump starts on many diesels as soon as your ignition is switched on — so leave it off. AdBlue does not mix with diesel — it sinks to the bottom of that tank, where your fuel is sucked from — so don't top up with diesel to dilute it.

Ask the staff to help push your car clear of the pump if you are on a forecourt — the Esso, the Logs Direct or somewhere else. If you are on your own drive around Bolton Town End, leave the vehicle where it sits.

Stop as soon as it is safe and switch off, if your motor has already run. Come off the M6 — under 3 miles out of Bolton Town End — at the next junction. Roughly how far did it go? Crossing Bolton Town End is less a job than a run of under 5 miles to Lancaster, and so say.

What occurs when our engineers arrive around Bolton Town End

Our technicians come to the car wherever it has stopped, whether that is outside Bolton-le-Sands Church of England Primary School, near Christ Church or on your own drive. Which fluid got in, the quantity, and if it ran: our engineers ask since the replies set the work and price. During the phone call itself, you are told our quote — ahead of anything else.

The fuel system is then cleaned thoroughly, once the tank is drained. With AdBlue that counts more than with petrol: it crystallises and is corrosive to some of the metals in a fuel system, and so it doesn't wash out on its own. Once your filter is cleaned — or replaced, if required — clean diesel is added, and then your vehicle is tested. We do not leave until it has been started and is running properly.

With pumps safe on a working forecourt and quiet enough for use outside a house at night, most jobs in which your engine has not run need roughly half an hour once we are there. Paying happens on the day, not upfront, and you are given the paperwork your insurer asks for: an engineer report and a VAT invoice. Wrong-fuel cover is included in plenty of insurance policies — and so use the wait to check yours.
