Two fillers, two tanks: AdBlue in a diesel vehicle

Plenty of newer diesels around New Edlington, as well as Wadworth, carry on two liquids; your motor takes just your diesel. Your exhaust, not your engine, is where AdBlue goes: dosed into the fumes to clean them, from its own tank.

Each tank has one filler of its own. Under one flap, side by side: that's the layout on a lot of cars. On others, AdBlue's filler is beneath the bonnet or in the boot instead. Diesel gets filled at each filling station visit, again and again. A driver who has to stop and think where it goes usually fills the AdBlue side, from a bottle, and much less commonly. The mistake grows in the gap between them.

Wadworth: how AdBlue in the diesel tank takes place

Carelessness seldom causes it. What does is three things coming up at once.

Hurry comes from the warning. The car tells you as AdBlue runs low, and an empty tank sends the vehicle into limp mode — so the top-up gets done quickly, before work on a drive off Ratten Row, or heading home in the car park at White Hart.

Unfamiliar motors come next, too. Rentals, new vehicles and company vehicles place their fillers in new places, and the hand goes for the cap it used on the old one.

Third, the bottle fits: a diesel filler or AdBlue one, it goes in just as easily, and once the pour starts, no part stops it. The same few seconds settle it, in the middle of Wadworth or out in Wilsic.

Flushing a diesel fuel system after AdBlue, Wadworth

Which filler is for AdBlue, and which for diesel?

Whether a Wadworth forecourt or a driveway out in Old Edlington, take a few seconds over these before any is poured in.

  • Position can mislead; the cap does not. AdBlue ones are often blue or carry the word "AdBlue" — diesel caps usually don't.
  • On plenty of motors, size tells: AdBlue has the smaller filler neck.
  • A label inside the fuel flap frequently says which fuel goes where, on many motors. Check for it.
  • In the boot or under the bonnet: that is where the filler is if it's not by the diesel cap, and the handbook says which.
  • Ask the person who drove it last — before you leave, not when the light comes on — when you pick up a hire or company car from somewhere like the car park at Doncaster.

How to top up without AdBlue in your diesel tank

The day the light comes on, wherever across South Yorkshire, follow this routine.

  • Not in a rush on the side of Walnut Tree Hill, not on a slope, not with your engine running: park and switch off first.
  • Locate the AdBlue filler, check the cap, and say the word "AdBlue" aloud as you unscrew it. It sounds daft. It works.
  • Leave your diesel cap on. If both sit under one flap, check the diesel cap is still closed before you lift the bottle.
  • Using the bottle's own spout, pour slowly — and stop when it is full or the bottle is empty.
  • Before you start the vehicle, close the cap and look a second time that the diesel cap never came off.

Find at stage two or three that it has already gone into your diesel side? Then stop right there. Leave out stage five altogether.

Already put AdBlue in the diesel tank in Wadworth?

Do not start your engine: that is how the short order of things starts. Leave the ignition off as well, because on plenty of diesels switching it on alone starts the pump. Thinning it with extra diesel won't work, because AdBlue settles to the bottom instead of blending — and that's where your fuel is pulled from.

The attendants at Tesco, Applegreen or any forecourt will usually lend a hand pushing your car away if asked. Your own driveway in Wadworth is where it stays.

Stop as soon as it is safe and switch off, if the engine has already run. On the A1(M), under a mile from Wadworth, that means the next exit. A short hop across Wadworth is a smaller job than a run towards Doncaster, under 5 miles away, and so tell us about how far it went.

Our arrival around Wadworth, and what occurs next

Our van reaches the car anywhere it stopped — your own driveway, beside St John the Baptist, or by Wadworth Primary School. What liquid got in, the amount, and whether it ran: our technicians ask since those answers set the work and quote. On the phone call itself, you are told our quote — ahead of dispatch.

Next: draining, then a thorough flush of the whole system. AdBlue crystallises and is corrosive to some of the metals in a fuel system, so it doesn't wash out on its own — which is why that matters more here than with petrol. Testing is at the end: before that, fresh diesel goes in, and the filter is flushed or replaced as needed. Your engine is started next and tested to make sure it runs properly, all before our technicians head off.

If your engine hasn't run, the majority of jobs take about half an hour once we are there, using pumps that are fine on a working 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. Misfuelling cover is included in plenty of insurance policies — and so use the wait to look at yours.
