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

Diesel goes to the motor — yet plenty of current diesels seen round Mossley Brow and Sandbed carry a second liquid as well. Stored in a tank of its own, AdBlue is fed into the exhaust gas to clean it.

Every tank has a filler of its own. On a lot of cars the two sit side by side under the same flap; on others the AdBlue filler is in your boot or under the bonnet. Diesel gets filled on each filling station call-out, again and again. Rarely topped up, AdBlue usually goes in from a bottle, tipped by someone who has to stop and think what cap it needs. That gap is where the error lives.

AdBlue in your diesel tank in Mossley Brow: how it takes place

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

The warning comes first. As AdBlue runs low your 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 driveway off Mountain Street before work, or in the car park at Britannia Inn on the way home.

Next, your hand goes for the cap it knew on the old car — because a rental car, a new motor or a company car places the fillers somewhere your last one didn't.

Lastly, the spout goes in: a diesel filler or AdBlue one, it goes in just as readily, and once the tip begins, no part stops it. The same few seconds decide it, in the middle of Mossley Brow or out in Mossley.

Flushing a diesel fuel system after AdBlue, Mossley Brow

Telling the AdBlue filler from your diesel filler

Whether a Mossley Brow forecourt or a drive out in Mossley Cross, take a few seconds over these before anything goes in.

  • Where it sits misleads; the cap does not. AdBlue caps tend to be blue or carry the name "AdBlue" — diesel ones usually do not.
  • Plenty of cars give AdBlue the smaller filler of the two.
  • A label inside your fuel flap often says which fuel goes where, on plenty of motors. Look for it.
  • In your boot or under the bonnet: that's where your filler sits if it's not by your diesel cap, and the handbook says which.
  • The person who drove the vehicle last. On a hire or company car picked up from somewhere like the car park at Mossley (Manchester), ask before you leave, not when the light comes on.

Keeping AdBlue out of the diesel tank when you top up

For the day the warning appears — anywhere it is in Greater Manchester — a simple routine to follow.

  • Park then switch off. Not on a slope, not with the motor running, and not in a rush on the side of Hanover Street.
  • Say "AdBlue" out loud as you unscrew the cap, after you find the AdBlue filler and reading it. Silly, perhaps, yet it works.
  • Both behind one flap? Then confirm the lid on the diesel side stays closed ahead of lifting the bottle.
  • Slowly is best, through the bottle's own spout, until it's full or the bottle runs out.
  • Only after that, start the car: close the cap, check once more, and make sure your diesel cap was never opened.

Spot at stage two or three that it's already gone into the diesel side? So stop just there. Leave out stage five altogether.

Then the order of things is short. Do not start the motor. The fuel pump runs on many diesels the moment the ignition goes on — and so leave it off. Do not top up with diesel to thin it: AdBlue does not mix with diesel, it sinks to the bottom of the tank, where the fuel is sucked from.

The staff at Texaco, Gulf or any forecourt will usually help pushing the vehicle away when you ask. If you're on your own drive around Mossley Brow, leave it where it sits.

Already started? Stop when it is sensible, then turn off. Mossley Brow lies under 5 miles from the M60; there, use the first junction. A short hop across Mossley Brow is a smaller job than a run towards Manchester, under 10 miles away, so tell us roughly how far it went.

Our arrival in Mossley Brow, and what occurs next

The van comes to the car wherever it stopped — your own drive, beside St Joseph, or by St Joseph's RC Primary School. What liquid went in, the amount, and if it ran: we ask because the replies decide both work and price. On the phone call itself, you are told the price — ahead of anything else.

Then your tank is emptied and your system rinsed thoroughly. AdBlue crystallises and is corrosive to some of the metals in a fuel system, and so it doesn't wash out on its own — which is why the flush matters more here than with petrol. Once the fuel filter is cleaned — or renewed, if needed — clean diesel is added, and finally the vehicle is tested. Before we go, we start it and make sure that it is running smoothly.

Most jobs are finished in roughly half an hour once our technicians arrive, as long as your engine hasn't run — and the pumps our technicians use are safe on a live forecourt yet quiet after dark outside a house. Paying happens on the day, not upfront, and you receive the documents an insurer asks for: an engineer's report and a VAT invoice. Before we get there, take a look at your policy; plenty carry cover for misfuelling.
