Two fillers, two tanks: AdBlue in a diesel vehicle

Plenty of modern diesels around Cefn-mawr, like those in Acrefair, run on two liquids; your engine gets just your diesel. Kept in a tank of its own, AdBlue is sprayed into your exhaust stream and cleans it.

Separate tanks, different fillers. Some motors put the AdBlue filler in your boot or under the bonnet; plenty more have both together under one flap. Filling your diesel side at the pump goes on constantly. Rarely topped up, AdBlue usually comes from a bottle, tipped by a driver who has to stop and think what cap to use. The slip lives in that gap.

How does AdBlue in the diesel tank take place around Acrefair?

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

On a drive off Abernant Road before work, or in the car park outside Duke of Wellington on the way home: that's where the rushed top-up takes place. Why the rush? As AdBlue gets low your car tells you, and once it is gone, limp mode kicks in.

New-to-you cars come second, as well. Hire cars, new motors and company vehicles place their fillers differently, and habit goes for the cap used on the old one.

A spouted bottle finds no resistance at a diesel filler no more than at an AdBlue one. So the pour, after started, carries on. The same few seconds decide it, in the middle of Acrefair or out in Aber-nant.

Flushing a diesel fuel system after AdBlue, Acrefair

Which filler is for AdBlue, and which for diesel?

Check these before pouring, at a forecourt in Acrefair or a driveway over in Rhosymedre. A few seconds, that's all.

  • Colour and marking: an AdBlue cap is regularly blue, or says "AdBlue", where a diesel cap normally doesn't. Go by the cap, not its position.
  • Plenty of vehicles fit AdBlue the smaller filler of the two.
  • A label inside the fuel flap frequently shows which fuel goes where, on many vehicles. Check for it.
  • The handbook says which it is if the filler is not next to your diesel cap: the boot, or under the bonnet.
  • The person who drove the vehicle last. On a hire or company car collected from somewhere like the car park outside Ruabon, ask before you leave, not when the light comes on.

AdBlue top-ups that never reach the diesel tank

A routine for the day the light comes on, wherever across Wrexham that is.

  • Not in a rush on the side of Tref Y Nant Park, not on a slope, not with the motor running: park then switch off first.
  • Say "AdBlue" out loud as you unscrew the cap, once you find the AdBlue filler and read it. Silly, yes, yet it does the trick.
  • Both under one flap? So make sure the cap on the diesel filler stays closed before raising the bottle.
  • Finish once your tank fills or the bottle is empty; until then, tip slowly using the built-in spout.
  • Close the cap, and look again — making sure your diesel cap remained shut the whole time. After that, start the car.

Find at the second or third stage that AdBlue went into the wrong filler? That's where you stop. Never carry on to step five.

Put AdBlue in your diesel tank around Acrefair already?

Don't start the engine: that is where the short order of things starts. On plenty of diesels your ignition alone runs the fuel pump, and so do not switch the vehicle on. Diluting it with more diesel won't work, because AdBlue settles to the base rather than blending — and that is where the fuel is sucked from.

At a forecourt — Shell, Esso or any other — the attendants will usually help push the vehicle away, if you ask. Leave it where it is if you're on your own drive around Acrefair.

When your motor has been run by now, pull over safely and turn the vehicle off. The next exit means where to leave when you're on the M53, under 25 miles from Acrefair. About how far did it go? Hopping across Acrefair is smaller work than a trip of under 10 miles to Wrexham, and so tell us.

When our engineers get there in Acrefair, what happens?

Anywhere the car came to rest, be it outside Weston Rhyn Primary School, near Cefn Bank or on your own drive, the van comes to it. Those replies settle this work and the price, and so our technicians ask what got in, about how much, and whether it has run. You hear that price on the phone, before anybody heads out.

Emptying that tank comes next, then a full flush of your 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. A test is last: before that, fresh diesel goes in, and your filter is cleaned or replaced as needed. We don't leave until it has been fired up and is running correctly.

With pumps fine on a busy forecourt and quiet enough for use outside a house at night, most jobs where your engine has not run need about half an hour after our technicians are there. Your insurer usually wants the engineer's report and your VAT invoice, and both are yours at the end. Payment is on the day, with no money upfront. Plenty of insurance policies include misfuelling cover, so it's worth checking yours whilst we are on the way.
