AdBlue in a diesel motor: two tanks, two fillers

Many newer diesels on the roads about New Brimington and Middlecroft carry two liquids, not one. Diesel goes to the engine. Kept in a tank of its own, AdBlue is sprayed into your exhaust gas to clean it.

There is a filler for each tank. Some motors put the AdBlue filler in the boot or under the bonnet; plenty more place both side by side behind one flap. Topping up your diesel side at the petrol pump goes on all the time. A driver who has to stop and think where it goes normally tops up the AdBlue side, from a bottle, and much less often. That gap is where the error lives.

New Brimington: how AdBlue in the diesel tank takes place

Three things tend to line up, and carelessness is rarely one of them.

To start with, the warning. Low AdBlue triggers a warning from the vehicle, and letting it run out leads to limp mode — hence a rushed top-up, maybe before work off King Street, or at Markham Arms on the way home after work.

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

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 once it has started. Hollingwood Estate or the heart of New Brimington: it is the same few seconds in both.

The AdBlue filler and your diesel filler: telling them apart

Look at these before pouring, on a forecourt around New Brimington or a drive over in Barrow Hill. Seconds, no more.

  • The cap. The AdBlue cap is commonly blue, or marked "AdBlue". The diesel cap usually isn't. Read it instead of going by where it sits.
  • The size. On many cars the AdBlue filler neck is the smaller of the two.
  • The flap. Look inside your fuel flap for a label. Plenty of cars say there which fuel goes where.
  • Cannot find it beside the diesel filler? In that case check below the bonnet or inside the boot — the handbook will say where.
  • The person who drove it last. On a hire or company car collected from somewhere like the car park outside Chesterfield, ask before you leave, not when the light comes on.

AdBlue top-ups that never reach your diesel tank

When the light goes on, anywhere across Derbyshire, follow this routine.

  • Not in a rush on the side of Victoria Street, not on a slope, not with your motor running: park then switch off properly.
  • Find the AdBlue filler and read the cap. Say "AdBlue" out loud as you unscrew it. It sounds silly and it does the trick.
  • Both behind a single flap? So make sure the cap on your diesel filler stays shut before raising the bottle.
  • Gently does it, through the bottle's own spout, until it is full or the bottle is empty.
  • Close the cap and check a second time. Make sure your diesel cap was never opened. Only then start the car.

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

AdBlue in the diesel tank already, in New Brimington?

The short order of things, starting with not starting your engine. Leave the ignition off as well, because on plenty of diesels switching it on alone runs your pump. Thinning it with extra diesel fails, because AdBlue sinks to the bottom rather than blending — and that's where your fuel is sucked from.

If you are at a forecourt, whether it is the JET or the Sainsbury's, ask the attendants to help roll the vehicle clear of the petrol pump. Your own drive around New Brimington is the place it stays.

If your engine has already run, stop as soon as it is safe and switch off. Leave the M1 — under 3 miles out of New Brimington — at the first exit. Tell us roughly how far it went: a run towards Sheffield, under 10 miles away, is a bigger job than a short hop across New Brimington.

Our arrival in New Brimington, and what occurs next

Outside Henry Bradley Infant School, near St Michael & All Angels or on your own driveway: wherever the car has stopped, our technicians come to it. Which fluid got in, the quantity, and if it ran: our engineers ask since the answers set both work and price. You get that quote on the phone, before anybody heads out.

Then that tank is emptied and your system purged thoroughly. With AdBlue that matters more than with petrol: it crystallises and is corrosive to some of the metals in a fuel system, so it doesn't wash out on its own. Filter cleaned or, if it must be, replaced; fresh diesel in; then a check of your car. Before we go, we start it and make sure that it is running properly.

Most jobs are finished in roughly half an hour once our engineers arrive, provided your engine has not run — and the pumps our technicians use are safe on a live forecourt and quiet at night outside a house. Your insurer usually wants an engineer's report and your VAT invoice, and both are yours once the job is done. Payment comes on the day, with no deposit. Wrong-fuel cover is part of many insurance policies — and so make use of the wait to look at yours.
