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

Not one liquid but two: that is how plenty of modern diesels around Bishop Sutton and Newtown run, with diesel for the engine. Its own tank holds it, and from there it goes to your exhaust, where a spray cleans the gas.

There is a filler on each tank. Under one flap, next to each other: that is the arrangement on many cars. Elsewhere, AdBlue's filler sits under the bonnet or in the boot instead. At the petrol pump, the diesel side gets filled constantly. Far less frequently, the AdBlue side is topped up — mostly from a bottle, by a person working out where it goes. The mistake lives in that gap.

AdBlue in the diesel tank around Bishop Sutton: how it takes place

Rarely is it carelessness: usually three things coincide.

The warning comes first. As AdBlue runs low the car tells you, and if it runs out altogether, your vehicle drops into limp mode. So the top-up is done in a hurry: on a drive off Ham Lane before work, or in the car park at The Red Lion on the way home.

Next, the hand reaches for the cap it knew on the old vehicle — since a hire car, a new motor or a company car puts the fillers where your last one did not.

No part stops the tip once it has started, because a bottle with a spout goes into a diesel filler as readily as an AdBlue one. The bottle fits. Whether it happens in Hollow Brook or the middle of Bishop Sutton, it is the same few seconds.

Telling the AdBlue filler from your diesel filler

Be it a Bishop Sutton forecourt or a drive over in Sutton Wick, take a few seconds on these before any goes in.

  • Where it sits can mislead; the cap does not. AdBlue ones tend to be blue or carry the word "AdBlue" — diesel ones normally don't.
  • The size. On many motors the AdBlue filler neck is the smaller of the two.
  • A label inside your fuel flap often says which fuel goes where, on many vehicles. Look for it.
  • The handbook shows where it is if the filler is not next to your diesel cap: your boot, or under the bonnet.
  • Whoever had it before knows. Check when you pick up a hire car or fleet car — at Parson Street's car park, perhaps — not once the light appears.

Keeping AdBlue out of your diesel tank when you top up

The day the light goes on, wherever in Somerset, use this routine.

  • Park and switch off. Not on a slope, not with your motor running, and not in a rush on the side of The Street.
  • Find the AdBlue filler, check the cap, and say the name "AdBlue" aloud as unscrewing it. It sounds silly. It does the trick.
  • Both behind one flap? Then confirm the lid on your diesel filler stays closed ahead of raising the bottle.
  • Finish when the tank is topped up or the bottle runs dry; before that, pour gently through its built-in spout.
  • Only after that, start your car: close the cap, check once more, and make sure the diesel cap was never opened.

Stop there if you find, at step two or three, that you have already poured into the diesel side. Never carry on to stage five.

Bishop Sutton: already put AdBlue in your diesel tank?

Brief list, then. Top of it: the engine remains unstarted. Keep the ignition off too, because on many diesels it by itself runs the pump. Diluting it with more diesel fails, since AdBlue settles to the bottom rather than blending — and that's where your fuel is pulled from.

The attendants at Texaco, Esso or any forecourt will normally help to push the car away if you ask. At home in Bishop Sutton? So your car stays where it is.

If your motor has already run, stop as soon as it is safe and switch off. On the M32, under 10 miles from Bishop Sutton, that means the next exit. Distance matters — a quick hop across Bishop Sutton is a smaller job than heading under 10 miles towards Bristol — so tell us about how far it went.

When our engineers arrive around Bishop Sutton, what takes place?

Wherever the vehicle came to rest, whether outside Bishop Sutton Primary School, beside Chew Valley Library or at home, the van comes to it. The answers decide this work and the price, so our engineers ask what got in, about how much, and whether it has run. On the phone call itself, you hear our price — before dispatch.

Draining your tank comes next, then a full flush of your system. With AdBlue that counts more than with petrol: it crystallises and is corrosive to some of the metals in a fuel system, and so it does not wash out on its own. The filter flushed or, if needed, replaced; clean diesel in; then a check of the car. Next our technicians start the car and make sure it runs smoothly before we go.

If your motor hasn't run, the majority of jobs take about half an hour once we're there, using pumps that are safe 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. It's worth checking your insurance as the van travels to you: misfuelling cover is included with many policies.
