Why does AdBlue in a diesel car need its own filler?

Plenty of modern diesels around Tydfils well, like those in Georgetown, carry on two fluids; your engine gets only your diesel. AdBlue goes to the exhaust, where it is sprayed into the gas to clean it, and it lives in a tank of its own.

Each tank has its own filler. Under one flap, side by side: that is the arrangement on many vehicles. On others, AdBlue's filler is beneath the bonnet or in the boot instead. The diesel side is filled at the pump all the time. The AdBlue side is fuelled far less regularly, normally from a bottle, and usually by a person who has to stop and think where it goes. It is in that gap that the slip happens.

How does AdBlue in the diesel tank happen in Georgetown?

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

First, the warning. Low AdBlue triggers a message from the vehicle, and letting it run dry leads to limp mode — hence a rushed top-up, perhaps before work off Nantygwenith Street, perhaps at Grawen Arms on the way home after work.

New-to-you vehicles are next, as well. Hire cars, new vehicles and company motors place their fillers in new places, and the hand goes for the cap used on the old one.

No part stops the pour once it has started, because a bottle with a spout goes into a diesel filler as easily as an AdBlue one. The bottle fits. It takes a few seconds, whether in Ynys-fach or right in the centre of Georgetown.

Telling the AdBlue filler from your diesel filler

Whether a Georgetown forecourt or a drive over in Abermorlais, take a couple of seconds over these before anything goes in.

  • The cap. The AdBlue cap is often blue, or marked "AdBlue". Your diesel cap normally isn't. Read it rather than going by where it sits.
  • On plenty of vehicles, the size gives it away: AdBlue gets the smaller filler neck.
  • Lift the filler flap and check for a label — plenty of cars mark which belongs in which filler right there.
  • Can't see it next to the diesel inlet? In that case look below the bonnet or in the boot — the handbook will say which.
  • The person who drove the car last. On a hire or company car collected from somewhere like the car park at Merthyr Tydfil, ask before you leave, not when the light comes on.

Keeping AdBlue out of the diesel tank when you top up

For the day the warning comes on — wherever you are in Merthyr Tydfil — a routine to follow.

  • Park and switch off. Not on a slope, not with your engine running, and not in a rush on the side of Howell Close.
  • Find the AdBlue filler and read the cap. Say "AdBlue" out loud as you unscrew it. It sounds silly and it does the trick.
  • Both under one flap? So make sure the lid on your diesel filler is still closed ahead of raising the bottle.
  • Finish once your tank is topped up or the bottle is empty; before that, pour slowly through its own spout.
  • Before you start your car, close the cap and check again that the diesel cap never opened off.

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

Put AdBlue in your diesel tank around Georgetown already?

Short list, then. Top of that: your motor remains unstarted. Keep the ignition off as well, since on many diesels it alone runs the pump. Do not top up with diesel to thin it: AdBlue does not mix with diesel, it sinks to the bottom of your tank, where your fuel is pulled from.

On a forecourt — Applegreen, Esso or any other — the staff will usually help push your car away, when you ask. Your own drive around Georgetown is where it stays.

Already run? Stop once it's sensible, then switch off. Georgetown lies under 25 miles from the M4; there, take the next exit. Tell us roughly how far it went: a run towards Newport, under 25 miles away, is a bigger job than a short hop across Georgetown.

When we get there around Georgetown, what occurs?

Anywhere your car has stopped, whether outside the local primary school, beside Birthplace of Joseph Parry or on your own drive, our van travels to it. Both the work and our price depend on three replies — which fluid, what quantity, and whether it's run — so our technicians ask. That price is given on the call, before any van leaves.

Emptying that tank comes next, then a thorough flush of the fuel system. Not like petrol, AdBlue leaves crystals and eats at certain fuel-system metals, and none of that clears out unaided. Hence it matters more. Filter cleaned or, if needed, swapped; fresh diesel in; then a test of the car. The motor is started next and tested to make sure it runs correctly, all before we go.

If the engine hasn't run, most jobs take about half an hour once we are there, using pumps that are safe on a working forecourt and quiet enough to use outside a house at night. Nothing upfront; you settle up on the day. Afterwards, a VAT invoice and the report from the engineer go to you for your insurer. Misfuelling cover is included in many insurance policies — so use the wait to look at yours.
