Two fillers, two tanks: AdBlue in a diesel vehicle

No single liquid but two: that is what plenty of modern diesels around Brinsop and Tillington Common run, with diesel feeding your motor. Your exhaust, not the engine, is where AdBlue ends up: dosed into the gas to clean it, from a separate tank.

Each tank has its own filler. Under one flap, side by side: that is the layout on a lot of motors. Elsewhere, AdBlue's filler sits under the bonnet or in the boot instead. At the petrol pump, the diesel side gets filled all the time. Seldom topped up, AdBlue usually goes in from a bottle, tipped by a driver who has to stop and think which filler it needs. It's in that gap that the error lives.

How AdBlue in your diesel tank occurs in Brinsop

Carelessness rarely explains it. What does is three things lining up together.

The warning comes first. As AdBlue runs low your car tells you, and if it runs out completely, the vehicle goes into limp mode. So the top-up is done in a hurry: on a drive off Dovecotts before work, or in the car park outside the pub in the village on the way home.

Then the vehicle is new. A hire car, a new motor or a company car puts the fillers where your last one did not, and the hand reaches for the cap it would have 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. The same few seconds decide it, in the middle of Brinsop or out in Brinsop Common.

Flushing a diesel fuel system after AdBlue, Brinsop

Which filler is for AdBlue, and which for diesel?

Check these first, at a forecourt around Brinsop or a driveway out in Bishon Common. A few seconds, no more.

  • Blue and marking: an AdBlue cap is regularly blue, or says "AdBlue", where a diesel cap normally does not. Trust the cap, not its position.
  • Many vehicles give AdBlue the smaller filler of the two.
  • Check inside your fuel flap: many motors have a label there showing which fuel goes where.
  • Cannot see it beside your diesel inlet? In that case look beneath the bonnet or inside your boot — the owner's manual says where.
  • Whoever had it before knows. Ask as you pick up a rental or fleet car — at Hereford's car park, perhaps — not when the light appears.

Keeping AdBlue out of the diesel tank when you top up

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

  • Park then switch off. Not on a slope, not with your engine running, and not in a rush on the side of Glebe Close.
  • Say "AdBlue" out loud as you unscrew the cap, after finding the AdBlue filler and reading it. Daft, yes, yet it does the trick.
  • If both sit under one flap, check your diesel cap is still closed before you lift the bottle — then leave it on.
  • Using the bottle's own spout, pour slowly — and stop when it's full or the bottle is empty.
  • Before starting your car, close the cap and check again that your diesel cap was never came off.

Find during the second or third stage that AdBlue went in the wrong filler? That's where you stop. Step five is out.

Put AdBlue in the diesel tank around Brinsop already?

Then the order of things is short. Do not start your engine. On many diesels your ignition alone runs the fuel pump, so do not switch it on. Topping up with diesel will not dilute it: instead, AdBlue drops to the bottom of that tank, right where fuel is taken from.

The attendants at Asda Express, Shell or another forecourt will usually lend a hand pushing the car clear if asked. On your own drive in Brinsop? Then the vehicle stays where it is.

Where the engine has run already, pull over somewhere safe then turn the car off. The next junction is where to come off when you're on the M50, under 25 miles from Brinsop. Tell us about how far it went: a run towards Hereford, under 10 miles away, is a bigger job than a short hop across Brinsop.

When our engineers arrive around Brinsop, what happens?

The van reaches the vehicle wherever it stopped — your own drive, beside St George, or outside St Mary's CofE Primary School. Both the work and our price depend on three answers — which liquid, which amount, and if it has run — so our engineers ask. You get that quote on the phone, before anyone sets off.

Draining the tank comes next, then a thorough flush of your system. Much more than with petrol, it matters here: crystals form, some metals are attacked, and nothing clears away on its own, however long it sits. Once your filter is cleaned — or replaced, if required — fresh diesel is added, and finally your vehicle is tested. Before leaving, our engineers start it and confirm that it's running smoothly.

With pumps fine on a busy forecourt and quiet enough for use outside a house at night, most jobs where your motor has not run need roughly half an hour after our engineers arrive. You pay on the day, with nothing upfront, and get a VAT invoice and an engineer report for your insurer. It is worth checking your policy while we travel to you: misfuelling cover comes with plenty of policies.
