AdBlue in a diesel motor: two tanks, two fillers

Many newer diesels on the roads around Poolstock and Wigan carry two liquids, not one. Diesel goes to your motor. AdBlue goes to the exhaust, where it is sprayed into the gas to fresh it, and it lives in a tank of its own.

Different tanks, different fillers. On a lot of motors the two sit side by side under the same flap; on others the AdBlue filler is in the boot or under the bonnet. The diesel side is fuelled at the petrol pump all the time. Much less frequently, the AdBlue side is filled — normally from a bottle, by a person working out where it goes. Mistakes happen in that gap between them.

Poolstock: how AdBlue in your diesel tank happens

Carelessness seldom explains it. What does is three things coming up together.

The warning comes first. As AdBlue runs low the vehicle 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 driveway off Carlton Street before work, or in the car park at Honeysuckle on the way home.

The old car's filler is where your hand goes — but a hire car, a new car or a company car keeps the fillers somewhere else. That is the second thing: a strange vehicle.

A spouted bottle finds no obstacle at a diesel filler any more than at an AdBlue one. So the pour, once begun, carries on. The same few seconds settle it, in the middle of Poolstock or out in Worsley Mesnes.

The AdBlue filler and your diesel filler: telling them apart

Before you pour anything, whether on a driveway in Lower Ince or a forecourt around Poolstock, check these. They take a few seconds.

  • Blue and marking: an AdBlue cap is commonly blue, or says "AdBlue", where a diesel cap normally doesn't. Trust the cap, not its position.
  • Plenty of vehicles fit AdBlue the smaller filler of the two.
  • Lift the filler flap and check for a label — many cars show which goes in which filler right there.
  • Can't find it beside the diesel inlet? Then look beneath the bonnet or in your boot — the owner's manual will say which.
  • Picking up a hire or company car, perhaps at the car park outside Wigan North Western? Ask whoever drove it last before you set off, rather than once the light comes on.

How to top up without AdBlue in your diesel tank

When the light goes on, wherever in Greater Manchester, use this routine.

  • Stop somewhere level, engine off, with time to spare — not rushing on the side of Poolstock.
  • Daft as it sounds, saying "AdBlue" aloud while you unscrew the cap works — once you've located the filler and read the cap.
  • If both sit under one flap, check your diesel cap is still closed before you lift the bottle — then leave the vehicle on.
  • Stop once that tank fills or the bottle runs dry; until then, tip gently using its built-in spout.
  • Before you start the vehicle, close the cap and look a second time that your diesel cap never opened off.

Stop there if you find, at step two or three, that you have already poured into your diesel side. Stage five is out.

Poolstock: already put AdBlue in the diesel tank?

Brief order, then. Top of that: your engine remains off. Keep your ignition off as well, since on many diesels it alone starts your fuel pump. Diluting it with extra diesel won't work, since AdBlue sinks to the base instead of blending — and that is where the fuel is pulled from.

If you are at a forecourt, whether it is the Asda or the Tesco, ask the attendants to help roll the vehicle clear of the petrol pump. At home in Poolstock? Then the vehicle remains put.

If your engine has already run, stop as soon as it is safe and switch off. The next exit means where to come off if you're on the Bryn Spur, under 3 miles from Poolstock. Tell us roughly how far it went: a run towards Salford, under 15 miles away, is a bigger job than a short hop across Poolstock.

Poolstock: what happens when we get there

Wherever your car came to rest, whether by St James' Church of England Primary School, near St James' Church or on your own drive, the van comes to it. We ask what went in, about how much, and whether it has run, because the answers decide the work and the quote. During the phone call itself, you are told our price — ahead of dispatch.

Next: draining, then a full flush of the whole system. More than with petrol, it counts here: crystals form, certain metals are attacked, and none of it washes out unaided, however long it sits. Filter cleaned or, if needed, swapped; fresh diesel in; then a test of your car. The engine is fired up next and checked to make sure it runs smoothly, all before our engineers head off.

If your engine hasn't run, the majority of jobs take about half an hour once we're there, using pumps that are fine on a busy forecourt and quiet enough to use outside a house at night. You pay on the day, with nothing upfront, and get a VAT invoice and an engineer report for your insurer. Plenty of insurance policies include misfuelling cover, and so it's worth checking yours while we're on the way.
