Two fillers, two tanks: AdBlue in a diesel vehicle

No single fluid but two: that's how many newer diesels around Hogley Green and Holmbridge run, with diesel feeding your motor. Stored in a tank of its own, AdBlue is sprayed into your exhaust stream to clean it.

Every tank comes with a filler of its own. Under one flap, side by side: that's the arrangement on many motors. On others, AdBlue's filler sits beneath the bonnet or in your boot instead. The diesel side is topped up at the petrol pump all the time. Someone who has to stop and think where it goes usually tops up the AdBlue side, from a bottle, and much less often. The slip lives in that gap.

How does AdBlue in your diesel tank occur in Hogley Green?

It's rarely carelessness. Three things tend to line up.

First, the warning. Low AdBlue brings a warning from the vehicle, and letting it run out means limp mode — so a hurried top-up, perhaps before work off Yew Tree Lane, or outside The Stumble Inn on the way home after work.

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

A spout-topped bottle finds no obstacle at a diesel filler no more than at an AdBlue one. So the pour, after begun, carries on. It takes a few seconds, whether in Hinchliffe Mill or bang in the centre of Hogley Green.

Flushing a diesel fuel system after AdBlue, Hogley Green

The AdBlue filler and the diesel filler: telling them apart

Be it a Hogley Green forecourt or a drive over in Upperthong, take a few seconds over these before anything is poured in.

  • Read the cap rather than going by position: AdBlue caps are often blue or marked "AdBlue", and diesel caps usually are not.
  • Many vehicles fit AdBlue the smaller neck of the two.
  • A label inside the fuel flap often says which fuel goes where, on many cars. Look for it.
  • The handbook. If the filler is not by the diesel cap, it's in the boot or under the bonnet, and the handbook says which.
  • The person who drove the car last. On a hire or company car picked up from somewhere like the car park at Brockholes, ask before you leave, not when the light comes on.

AdBlue top-ups that never reach your diesel tank

A routine for the day the light comes on, wherever across West Yorkshire that is.

  • Not in a rush on the side of Booth House Lane, not on a slope, not with your engine running: park then switch off first.
  • Say "AdBlue" out loud as you unscrew the cap, once you find the AdBlue filler and reading it. Daft, yes, but it does the trick.
  • The two behind one flap? So make sure the cap on the diesel filler stays closed before raising the bottle.
  • Gently does it, through the bottle's own spout, till it's full or the bottle runs out.
  • Close the cap and check once more. Make sure the diesel cap was never opened. Only then start the car.

Spot at stage two or three that it has already gone into your diesel side? So stop right there. Step five stays out.

Put AdBlue in your diesel tank in Hogley Green already?

Short order, then. Top of it: the engine stays unstarted. Don't switch your ignition on; on many diesels that alone runs the fuel pump. Do not top up with diesel to thin it: AdBlue doesn't mix with diesel, it sinks to the bottom of that tank, where the fuel is drawn from.

At a forecourt — Murco, Morrisons or another — the staff will normally help push your car clear, if you ask. At home in Hogley Green? Then the vehicle stays where it is.

Already run? Stop when it's safe, then turn off. On the M62, under 10 miles from Hogley Green, that means the next exit. Roughly how far did it go? Crossing Hogley Green is smaller a job than a trip of under 25 miles to Wakefield, and so say.

Our arrival around Hogley Green, and what takes place next

The van comes to the car anywhere it stopped — your own driveway, near Booth House Gallery, or outside Hinchliffe Mill Junior and Infant School. Both the work and the quote depend on three replies — what liquid, what quantity, and if it has run — so our technicians ask. That quote comes over the phone, before any van leaves.

Draining the tank comes next, followed by a thorough flush of your system. 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 that counts more with AdBlue than with petrol. The filter flushed or, where it must be, replaced; clean diesel in; and then a test of the vehicle. We don't go until it has been fired up and is running properly.

Unrun vehicles mostly need a half-hour visit after arrival. The kit is fine on a busy filling station, and quiet enough for a driveway after dark. No money in advance; you settle up on the day. Afterwards, a VAT invoice and the report from the engineer are handed to you for your insurer. Misfuelling cover is included in many insurance policies — so make use of the wait to check yours.
