Two fillers, two tanks: AdBlue in a diesel vehicle

Not one fluid but two: that is how plenty of modern diesels around Wilsey and Sturmer carry, with diesel for your motor. AdBlue goes to the exhaust, where it is sprayed into the gas to clean it, and it lives in a tank of its own.

Separate tanks, separate fillers. Other vehicles put the AdBlue filler in the boot or under the bonnet; a lot of others place both side by side under one flap. Diesel goes in at every forecourt visit, again and again. The AdBlue side is filled far less commonly, usually from a bottle, and usually by a person who has to stop and think where it goes. It is in that gap that the error lives.

AdBlue in the diesel tank around Wilsey: how it happens

Rarely is it carelessness: normally three things line up.

The warning comes first. As AdBlue runs low the car tells you, and if it runs out completely, your vehicle drops into limp mode. So the top-up is done in a hurry: on a driveway off Rockall Close before work, or in the car park outside The Royal Exchange 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 a second thing: a new motor.

Nothing stops the tip after it has started, because a bottle with a spout goes into a diesel filler as easily as an AdBlue one. The bottle fits. Whether it takes place in Chalkstone or the middle of Wilsey, it's the same few seconds.

Flushing a diesel fuel system after AdBlue, Wilsey

Which filler is for AdBlue, and which for diesel?

A few seconds is all the checks take — so run through them before you tip anything, on a driveway in Little Wratting or a forecourt around Wilsey.

  • Read the cap instead of going by position: AdBlue caps are often blue or marked "AdBlue", and diesel ones usually are not.
  • The size. On many vehicles the AdBlue filler neck is the smaller of the two.
  • A label inside the fuel flap frequently shows which fuel goes where, on many cars. Check for it.
  • Cannot find it beside the diesel inlet? Then check below the bonnet or inside the boot — the handbook will say where.
  • Collecting a hire or company car, say at the car park outside Dullingham? Check with the person who drove the car last before you set off, rather than once the light comes on.

Topping up AdBlue without it reaching your diesel tank

When the light goes on, wherever across Suffolk, follow this routine.

  • Pull in on level, engine off, with time to spare — never hurried on the side of Orkney Close.
  • Find the AdBlue filler and read the cap. Say "AdBlue" out loud as you unscrew it. It sounds daft and it does the trick.
  • Leave the diesel cap on. If both sit under one flap, check the diesel cap is still closed before you lift the bottle.
  • Stop when the tank fills or the bottle is empty; before that, pour slowly using the own spout.
  • Shut the cap, and check once more — making sure your diesel filler stayed shut the whole time. After that, start your car.

Stop there if you find, at step two or three, that you have already poured into your diesel side. Do not go on to stage five.

Put AdBlue in the diesel tank in Wilsey already?

Then the order of things is short. Don't start the motor. Do not switch the ignition on; on plenty of diesels that alone runs the fuel pump. Diluting it with more diesel won't work, since AdBlue sinks to the base rather than mixing — and that is where your fuel is drawn from.

The staff at Esso, JET or another forecourt will normally help pushing your car away when you ask. Your own drive around Wilsey is the place it stays.

Where the motor has been run by now, pull over somewhere safe and switch it off. Leave the M11 — under 15 miles out of Wilsey — at the next exit. Tell us about how far it went: a run towards Cambridge, under 25 miles away, is a bigger job than a short hop across Wilsey.

Our arrival in Wilsey, and what takes place next

Anywhere the car came to rest, whether by Coupals Primary Academy, near Burial Mound or at home, our van comes to it. We ask what was put in, about how much, and if it's run, since the answers settle the work and the price. The price comes over the phone, ahead of any van leaving.

Then your tank is drained and your system flushed thoroughly. More than with petrol, it counts here: the crystals form, certain metals corrode, and none of it clears out unaided, however long it sits. Filter cleaned or, if it must be, swapped; fresh diesel in; then a test of the car. After that our technicians fire it up and make sure it runs properly before leaving.

If the motor hasn't run, most jobs take about half an hour once we're there, using pumps that are safe on a busy forecourt and quiet enough to use outside a house after dark. Your insurer usually wants an engineer's report and the VAT invoice, and both are yours once the job is done. Payment comes on the day, with no money upfront. Plenty of insurance policies include misfuelling cover, and so it is worth checking yours while we're on the way.

AdBlue drains across Suffolk, Wilsey included

Wilsey is a residential suburb, and the vans that cover it also work the towns near it, Calford Green and Haverhill among them, across the CB postcode area. Quickest of all: quote a CB9 0 postcode to our van.

Shifting the vehicle isn't needed. A driveway, a lay-by on the way to Millfields County Wildlife Site, a side street near Anne of Cleves House: our engineers drain the car where it is. Tricky to explain, like the back of CineWorld Haverhill? By a county line? Checking beats assuming, so phone.
