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

Not one liquid but two: that's how many newer diesels near Old Glossop and Whitfield Park run, with diesel feeding your engine. AdBlue's own tank holds it, and from there it goes to your exhaust, and there spraying treats the gas.

Different tanks, different fillers. Under one flap, side by side: that's the arrangement on a lot of vehicles. Elsewhere, AdBlue's filler sits beneath the bonnet or in your boot instead. At the pump, the diesel side gets filled all the time. A driver who has to stop and think where it goes normally fills the AdBlue side, from a bottle, and far less commonly. It is in that gap that the slip lives.

How does AdBlue in your diesel tank happen around Old Glossop?

Carelessness seldom causes it. What does is three things lining up together.

On a drive off Wesley Street before work, or in the car park outside The Queens Arms heading home: that's where the rushed top-up happens. Why the rush? As AdBlue runs low the car tells you, and if it's gone, limp mode follows.

Unfamiliar vehicles come second, too. Rentals, new cars and company vehicles put their fillers differently, and the hand goes for the cap it used on the old one.

And the bottle fits. A bottle with a spout goes into a diesel filler as easily as an AdBlue one, and so nothing stops the pour once it has started. It takes seconds, whether in Glossop or bang in the centre of Old Glossop.

Flushing a diesel fuel system after AdBlue, Old Glossop

Telling the AdBlue filler from the diesel filler

Be it a Old Glossop forecourt or a driveway out in Higher Dinting, take a couple of seconds over these before any is poured in.

  • The cap. The AdBlue cap is regularly blue, or marked "AdBlue". Your diesel cap usually isn't. Read it rather than going by position.
  • Many cars give AdBlue the smaller filler of the two.
  • Lift the filler flap and check for a label — plenty of cars show what goes in each filler right there.
  • Cannot find it next to the diesel filler? In that case look beneath the bonnet or in the boot — the owner's manual says where.
  • Whoever had it before knows. Ask as you collect a hire car or company car — from Glossop's car park, say — rather than when the warning appears.

AdBlue top-ups that never reach your diesel tank

When the light comes on, wherever around Derbyshire, use this routine.

  • Turn off after you park — flat ground, engine off, and not rushed by Church Street South at the roadside.
  • Find the AdBlue filler and read the cap. Say "AdBlue" out loud as you unscrew it. It sounds silly and it works.
  • If both sit under one flap, check your diesel cap is still closed before you lift the bottle — then leave the vehicle on.
  • Pour slowly, using the bottle's own spout. Stop when it's full or when the bottle is empty.
  • Close the cap and check a second time. Make sure the diesel cap was never opened. Only then start the car.

Discover at the second or third step that the bottle went in the diesel filler? That's where you stop. Step five is out.

Already put AdBlue in your diesel tank around Old Glossop?

The short order of things, beginning with no starting your motor. Don't switch your ignition on; on many diesels that alone runs the fuel pump. Diluting it with more diesel fails, because AdBlue sinks to the base rather than blending — and that's where the fuel is drawn from.

If you are at a forecourt, whether it is the Esso or the Tesco, ask the attendants to help roll the vehicle away from the pump. At home in Old Glossop? So the vehicle stays where it is.

Already started? Pull over when it is safe, then turn off. Old Glossop sits under 5 miles from the M67; on it, take the next exit. Tell us roughly how far it went: a run towards Manchester, under 15 miles away, is a bigger job than a short hop across Old Glossop.

Our arrival around Old Glossop, and what takes place next

Our van comes to the vehicle wherever it stopped — your own drive, beside All Saints, or by All Saints Catholic Voluntary Academy. What liquid was put in, the quantity, and whether it ran: our technicians ask because those answers set both work and price. The price is given on the call, ahead of any van leaving.

Then the tank is drained and the system flushed thoroughly. AdBlue crystallises and is corrosive to some of the metals in a fuel system, so it does not wash out on its own — which is why the flush counts more here than with petrol. The filter cleaned or, where it must be, replaced; fresh diesel in; then a check of the vehicle. Before we go, we start the car and confirm that it is running properly.

Most jobs are finished in about half an hour once we get there, as long as your motor hasn't run — and the pumps our engineers use are fine on a busy forecourt yet quiet after dark beside a house. Your insurer usually wants the engineer's report and the VAT invoice, and you get both once this job is done. Payment is on the day, with no money upfront. Plenty of insurance policies include misfuelling cover, so it's worth checking yours whilst we are on the way.
