AdBlue in a diesel vehicle, and its separate tank

No single fluid but two: that's what plenty of modern diesels around Kingswinford and Bromley carry, with diesel for your motor. Stored in a tank of its own, AdBlue is fed into the exhaust gas to clean it.

There's a filler on each tank. Plenty of cars have a single flap for the two, while some put the AdBlue filler to the boot or under the bonnet. Diesel gets filled at every forecourt visit, week in, week out. Far less frequently, the AdBlue side is topped up — mostly from a bottle, by a person working out where it goes. That gap is where the mistake lives.

Kingswinford: how AdBlue in the diesel tank occurs

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

Hurry comes from the warning. Your car warns you as AdBlue runs low, and a dry tank puts the vehicle into limp mode — so the top-up happens in a rush, before work on a drive off Manor Park, or on the way home in the car park at The Cottage Inn.

The old car's cap is where your hand reaches — yet a hire car, a new motor or a company car puts the fillers somewhere else. That's a second factor: a new vehicle.

No part stops the tip once it has started, since a bottle with a spout goes into a diesel filler as readily as an AdBlue one. The bottle fits. Whether it happens in Wall Heath or the middle of Kingswinford, it's the same few seconds.

Flushing a diesel fuel system after AdBlue, Kingswinford

Telling the AdBlue filler from your diesel filler

Be it a Kingswinford forecourt or a drive over in Pensnett, take a couple of seconds over these before anything is poured in.

  • Blue and lettering: an AdBlue cap is regularly blue, or says "AdBlue", where a diesel cap normally does not. Trust the cap, not its position.
  • Many cars fit AdBlue the smaller filler of the two.
  • Look inside your fuel flap: many vehicles carry a label there saying which fuel goes where.
  • In your boot or under the bonnet: that's where the filler sits if it's not by your diesel cap, and the handbook says which.
  • Ask the person who drove it last — before you leave, not when the light comes on — when you collect a hire or company car from somewhere like the car park outside Stourbridge Town.

AdBlue top-ups that never reach the diesel tank

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

  • Pull in somewhere level, motor off, with time in hand — not rushing on the side of Orchard Court.
  • Find the AdBlue filler, check the cap, and speak the name "AdBlue" aloud while you unscrew it. It seems daft. It works.
  • Leave the diesel cap on. If both sit under one flap, check your diesel cap is still closed before you lift the bottle.
  • Slowly is best, through the bottle's own spout, until it's full or the bottle runs out.
  • Close the cap and check again. Make sure the diesel cap was never opened. Only then start your car.

Stop there if you find, at stage two or three, that you have already poured into your diesel side. Don't go on to step five.

AdBlue in the diesel tank already, around Kingswinford?

What follows is a short order of things, beginning with not starting the engine. Do not switch your ignition on; on plenty of diesels that alone runs the fuel pump. Thinning it with extra diesel fails, since AdBlue settles to the bottom instead of blending — and that's where your fuel is pulled from.

Ask the attendants to help push the vehicle away from the pump if you're on a forecourt — the Esso, the Morrisons or somewhere else. Leave it where it is if you are on your own driveway around Kingswinford.

Already run? Stop when it is sensible, then turn off. Kingswinford sits under 10 miles from the M5; on it, use the next exit. About how far did it go? Hopping across Kingswinford is smaller work than a trip of under 10 miles to Wolverhampton, and so say.

Kingswinford: what takes place when our technicians arrive

We come to the car wherever it has stopped, whether that is outside St Mary's CofE Primary School, near Kingswinford Library or on your own drive. Both the work and our quote depend on three answers — what liquid, which amount, and if it's run — so our technicians ask. You hear that price by phone, before anyone heads out.

After that: draining, then a full flush of the whole system. More than with petrol, it matters with AdBlue: the crystals form, some metals corrode, and none of that washes out unaided, no matter how long it is left. After the fuel filter is cleaned — or replaced, where required — clean diesel is added, and finally the vehicle gets tested. Your engine is fired up next and checked to confirm it runs smoothly, all before we head off.

Unstarted vehicles mostly mean a half-hour visit from the moment we arrive. The equipment is fine on a busy filling station, and hushed enough for a driveway late at night. Nothing in advance; you settle up on the day. At the end, a VAT invoice and the report from the engineer are handed to you for your insurer. It's worth checking your policy while we travel to you: misfuelling cover comes with many policies.
