AdBlue in a diesel motor: two tanks, two fillers

Plenty of current diesels on the roads about Athersley North and Honeywell carry two liquids, not one. Diesel goes to your engine. AdBlue goes to your exhaust, where it is sprayed into the gas to fresh it, and it lives in a tank of its own.

Each tank has one filler of its own. Under one flap, next to each other: that's the arrangement on many vehicles. On others, AdBlue's filler sits under the bonnet or in the boot instead. The diesel side is fuelled at the petrol pump all the time. Far less commonly, the AdBlue side is topped up — mostly from a bottle, by a person working out where it goes. The error lives in that gap.

AdBlue in the diesel tank in Athersley North: how it occurs

Three things tend to come together, and carelessness is seldom one of them.

On a drive off Laithes Lane before work, or in the car park outside Athersley Social Club heading home: that's where the hurried top-up takes place. What is the reason for the rush? As AdBlue runs low the vehicle warns you, and if it is gone, limp mode kicks in.

New-to-you vehicles are next, as well. Rentals, new cars and company vehicles place their fillers differently, and habit goes for the cap it used on the old one.

A spout-topped bottle finds no obstacle at a diesel filler no more than at an AdBlue one. And so the pour, after begun, keeps on. It takes seconds, whether out in New Lodge or right in the centre of Athersley North.

How to tell the AdBlue filler from the diesel one

A few seconds is all these take — so check them before you pour anything, on a driveway in Carlton or a forecourt in Athersley North.

  • Read the cap rather than going by where it sits: AdBlue caps are frequently blue or marked "AdBlue", and diesel ones usually aren't.
  • Plenty of vehicles fit AdBlue the smaller filler of the two.
  • Open the filler flap and check for a label — many vehicles mark which goes in each filler right there.
  • In the boot or under the bonnet: that is where the filler sits if it is not by your diesel cap, and the handbook tells you which.
  • Whoever had it before will know. Check when you collect a hire car or company car — from Barnsley's car park, perhaps — not when the warning comes on.

Keeping AdBlue out of the diesel tank when you top up

The day the light comes on, wherever in South Yorkshire, use this routine.

  • Stop on level, engine off, with time in hand — never rushing on the side of Arnold Avenue.
  • Find the AdBlue filler, read the cap, and say the name "AdBlue" out loud as you unscrew it. It sounds silly. It does the trick.
  • Leave the diesel cap on. If both sit under one flap, check your diesel cap is still closed before you lift the bottle.
  • Using the bottle's own spout, tip slowly — and stop when it's full or the bottle is empty.
  • Close the cap and check a second time. Make sure the diesel cap was never opened. Only then start the vehicle.

Stop there if you find, at step two or three, that you've already poured into your diesel side. Stage five stays out.

Put AdBlue in the diesel tank around Athersley North already?

Do not start the engine: that's where the short order of things begins. Don't switch the ignition on; on many diesels that alone runs the fuel pump. AdBlue does not mix with diesel — it sinks to the bottom of your tank, where your fuel is drawn from — so don't top up with diesel to dilute it.

If you are on a forecourt, whether it's the The Co-operative or the Shell, ask the staff to help roll the car away from the petrol pump. On your own drive in Athersley North? Then the car remains put.

Already started? Stop when it's safe, then turn off. The next junction means the place to come off if you are on the M1, under 3 miles from Athersley North. Tell us about how far it went: a run towards Wakefield, under 10 miles away, is a bigger job than a short hop across Athersley North.

Athersley North: what happens when we turn up

Wherever the car has stopped, be it outside Laithes Primary School, beside St Helen or at home, the van comes to it. Our technicians ask what went in, about how much, and whether it has run, since the answers settle this work and our quote. Nobody sets off until you have had the quote by phone.

Then your tank is drained and the fuel system rinsed thoroughly. With AdBlue that matters more than with petrol: it crystallises and is corrosive to some of the metals in a fuel system, and so it does not wash out on its own. Testing comes at the end: before that, clean diesel is added, and the fuel filter is cleaned or replaced as needed. Then our technicians start the car and check it runs correctly before we leave.

Using pumps fine on a working forecourt and quiet enough for use outside a house at night, most jobs where the engine has not run need roughly half an hour once our engineers are there. The insurer usually wants an engineer's report and your VAT invoice, and both are yours at the end. Payment comes on the day, with no deposit. While we travel, have a look at your insurance documents; plenty carry cover for misfuelling.
