Two fillers, two tanks: AdBlue in a diesel car

Diesel feeds the engine — but plenty of newer diesels driven round Ashbrook and Battle Field hold another liquid as well. The exhaust, not the engine, is where AdBlue ends up: dosed into the fumes to clean it, from a separate tank.

There's a filler for every tank. On a lot of vehicles the two sit side by side under the same flap; on others the AdBlue filler is in your boot or under the bonnet. At the petrol pump, the diesel side is topped up constantly. Rarely filled, AdBlue usually goes in out of a bottle, poured by someone who has to stop and think which filler it needs. It is in that gap that the error lives.

How AdBlue in the diesel tank takes place around Ashbrook

It's rarely carelessness. Three things tend to line up.

The warning comes first. As AdBlue runs low the car tells you, and if it runs out completely, the car goes into limp mode. So the top-up is done in a hurry: on a drive off Longhills Road before work, or in the car park at Old Coppers Malt House on the way home.

Then the vehicle is strange. A hire car, a new car or a company car puts the fillers where your last one did not, and your hand reaches for the cap it would have used on the old one.

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 once it has started. Whether it takes place in Cunnery or the middle of Ashbrook, it is the same few seconds.

Flushing a diesel fuel system after AdBlue, Ashbrook

Which filler is for AdBlue, and which for diesel?

Be it a Ashbrook forecourt or a drive over in Hazler, take a few seconds on these before anything is poured in.

  • Colour and lettering: an AdBlue cap is often blue, or says "AdBlue", where a diesel cap normally does not. Trust the cap, not its position.
  • Look at the size: the smaller neck is, on many motors, the AdBlue one.
  • Lift the filler flap and check for a label — plenty of vehicles show what belongs in each filler right there.
  • The handbook shows which it is if the filler isn't next to the diesel cap: the boot, or under the bonnet.
  • The previous driver will know. Ask when you collect a rental or company car — at Church Stretton's car park, say — rather than when the light comes on.

Topping up AdBlue without it reaching the diesel tank

Anywhere around Shropshire the light comes on, this is a routine for the day.

  • Not in a rush on the side of Madeira Walk, not on a slope, not with the motor running: park then switch off properly.
  • Daft as it sounds, speaking "AdBlue" aloud as you unscrew the cap does the trick — after you have found the filler and read it.
  • If both sit under one flap, check the diesel cap is still closed before you lift the bottle — and leave the vehicle on.
  • Finish once the tank is topped up or the bottle runs dry; before that, pour gently using its own spout.
  • Before you start your car, shut the cap and look a second time that the diesel cap never opened off.

Spot at step two or three that it has already gone into your diesel side? So stop just there. Skip stage five altogether.

AdBlue in your diesel tank already, around Ashbrook?

Don't start your motor: that's how the short order of things starts. The fuel pump runs on many diesels the moment your ignition goes on — and so leave it off. Diluting it with extra diesel fails, since AdBlue sinks to the bottom instead of blending — and that's where your fuel is sucked from.

If you're at a forecourt, whether it is the Applegreen or the another forecourt nearby, ask the staff to help roll the vehicle clear of the petrol pump. Your own drive in Ashbrook is the place it stays.

Stop as soon as it is safe and switch off, if your motor has already run. The next exit means the place to leave when you're on the M54, under 25 miles from Ashbrook. Roughly how far did it go? Crossing Ashbrook is less work than a trip of under 50 miles to Wolverhampton, and so tell us.

Ashbrook: what happens when our engineers arrive

We come to your car wherever it has stopped, whether that's outside St Lawrence CofE Primary School, near War Memorial or on your own driveway. Both the work and the price depend on three answers — which liquid, what amount, and if it has run — so our engineers ask. The price comes on the call, before any van leaves.

Draining your tank comes next, followed by a full flush of your system. Unlike petrol, AdBlue forms crystals and eats at certain fuel-system metals, and neither washes out unaided. Hence it counts more. Once the filter is cleaned — or replaced, if required — clean diesel is added, and finally your car is tested. Your engine is started next and tested to be sure it runs smoothly, all before our technicians head off.

Unstarted cars mostly need a half-hour job after the moment we arrive. The equipment is fine on a busy forecourt, and hushed enough for a residential street after dark. The insurer usually wants an engineer's report and your VAT invoice, and you get both at the end. Payment comes on the day, with no money upfront. Many insurance policies include misfuelling cover, and so it is worth checking yours while we're on the way.

The car doesn't need to shift. Our technicians drain it where it is — a side street near Pump House, a lay-by on the way to Old Rectory Wood, a driveway. Ring and ask rather than guessing if you are close to a border, or somewhere hard to describe, like the back of St. Laurence's Parish Centre.
