Two fillers, two tanks: AdBlue in a diesel vehicle

Many current diesels on the roads around Kesgrave and Little Bealings carry two liquids, not one. Diesel goes to your motor. Kept in a tank of its own, AdBlue is sprayed into the exhaust gas to clean it.

Separate tanks, separate fillers. On a lot of vehicles the two sit side by side under the same flap; on others the AdBlue filler is in the boot or under the bonnet. Diesel goes in on every forecourt visit, week in, week out. The AdBlue side is topped up far less often, usually from a bottle, and usually by someone who has to stop and think where it goes. That gap is where the error lives.

AdBlue in the diesel tank around Kesgrave: how it occurs

Rarely is it carelessness: usually three things coincide.

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

The old car's cap is where the hand reaches — but a hire car, a new vehicle or a company car puts the fillers elsewhere. That's the second factor: a new vehicle.

And the bottle fits. A bottle with a spout goes into a diesel filler as easily as an AdBlue one, so nothing stops the pour after it has started. Whether it takes place in Rushmere Street or the middle of Kesgrave, it is the same few seconds.

Flushing a diesel fuel system after AdBlue, Kesgrave

Which filler is for AdBlue, and which for diesel?

A few seconds is all the checks take — so run through them before you pour anything, on a drive in Martlesham or a forecourt around Kesgrave.

  • The cap. The AdBlue cap is frequently blue, or marked "AdBlue". The diesel cap usually isn't. Read it instead of going by where it sits.
  • On plenty of vehicles, size gives it away: AdBlue has the smaller filler neck.
  • A label inside your fuel flap often shows which fuel goes where, on plenty of motors. Check for it.
  • In the boot or under the bonnet: that is where your filler is if it's not by your diesel cap, and the handbook says which.
  • The previous driver will know. Ask as you pick up a rental or fleet car — at Derby Road's car park, say — rather than once the light comes on.

Keeping AdBlue out of the diesel tank when you top up

For the day the light comes on — anywhere you are across Suffolk — a routine to use.

  • Turn off after you park — flat ground, motor stopped, and never in a rush by Sewell Wontner Close on the verge.
  • Daft as it sounds, speaking "AdBlue" aloud as you unscrew the cap works — once you've found the filler and read it.
  • The two under one flap? Then make sure the cap on your diesel filler is still shut ahead of raising the bottle.
  • Tip slowly, using the bottle's own spout. Stop when it is full or when the bottle is empty.
  • Before you start the vehicle, shut the cap and check again that the diesel cap was never opened off.

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

Kesgrave: already put AdBlue in your diesel tank?

What follows is a short order of things, starting with no starting your engine. On plenty of diesels the ignition alone runs the fuel pump, so don't switch it on. Diluting it with extra diesel won't work, since AdBlue settles to the base instead of blending — and that is where the fuel is pulled from.

If you're on a forecourt, whether it is the BP or the Tesco, ask the staff to help push the vehicle away from the petrol pump. Your own driveway around Kesgrave is the place it should stay.

Stop as soon as it is safe then switch off, if your engine has already run. The next junction is where to leave if you're on the M11, under 50 miles from Kesgrave. About how far did it go? Hopping across Kesgrave is smaller work than a trip of under 25 miles to Colchester, and so tell us.

Our arrival around Kesgrave, and what takes place next

Our van reaches your car anywhere it has come to rest — your own driveway, beside All Saints Church Hall, or outside Heath Primary School, Kesgrave. Those answers settle the work and the price, so our engineers ask what got in, about how much, and whether it's run. That price is given over the phone, before any van leaves.

The system is then rinsed thoroughly, after the tank is cleared. AdBlue crystallises and is corrosive to some of the metals in a fuel system, and so it does not wash out on its own — which is why the flush matters more with AdBlue than with petrol. The filter flushed or, where it must be, replaced; clean diesel in; then a test of the car. We don't go until it has been started and is running properly.

With pumps fine on a working forecourt and quiet enough to use outside a house at night, most jobs in which your motor has not run take about half an hour once we arrive. Payment happens on the day, not upfront, and you are given the paperwork your insurer asks for: an engineer's report and a VAT invoice. While we travel, take a look at your policy; plenty carry cover for misfuelling.
