Two fillers, two tanks: AdBlue in a diesel car

Many current diesels on the roads around Kings Hedges and Milton carry two liquids, not one. Diesel goes to your motor. The exhaust, not your engine, is where AdBlue ends up: dosed into the fumes to clean it, from its own tank.

Different tanks, different fillers. Plenty of motors have a single flap for the two, while some put the AdBlue filler to the boot or under the bonnet. Filling your diesel side at the petrol pump happens constantly. Rarely filled, AdBlue usually comes out of a bottle, poured by someone who has to stop and think what filler to use. The mistake grows in the gap between them.

How does AdBlue in your diesel tank occur in Kings Hedges?

It is rarely carelessness. Three things tend to line up.

Hurry comes from the warning. The vehicle warns you as AdBlue runs low, and a dry tank puts the vehicle into limp mode — so the top-up gets done quickly, before work on a drive off Crowland Way, or on the way home in the car park at The Ship.

Next, the hand goes for the cap it would have used on the old motor — because a rental car, a new car or a company car puts the fillers somewhere your last one didn't.

No part halts the tip after it has started, since a bottle with a spout goes into a diesel filler as readily as an AdBlue one. The bottle fits. Arbury or the heart of Kings Hedges: it takes the same few seconds either way.

Flushing a diesel fuel system after AdBlue, Kings Hedges

Which filler is for AdBlue, and which for diesel?

Before you pour anything, whether on a driveway in Impington or a forecourt around Kings Hedges, check these. They take a couple of seconds.

  • Read the cap rather than going by where it sits: AdBlue ones are often blue or marked "AdBlue", and diesel ones normally aren't.
  • Plenty of cars give AdBlue the smaller neck of the two.
  • The flap. Look inside the fuel flap for a label. Plenty of cars say there which fuel goes where.
  • Can't see it beside the diesel filler? Then look below the bonnet or inside your boot — the handbook says where.
  • Picking up a hire or company car, say at the car park outside Cambridge North? Ask whoever drove the car last before leaving, rather than when the light goes on.

AdBlue top-ups that never reach the diesel tank

The day the light comes on, anywhere in Cambridgeshire, follow this routine.

  • Turn off after you park — flat ground, motor off, and not rushed by Campkin Road at the roadside.
  • Locate the AdBlue filler, check the cap, and speak the name "AdBlue" out loud as you unscrew it. It sounds daft. It works.
  • Both under one flap? Then confirm the cap on your diesel filler stays shut ahead of raising the bottle.
  • Gently does it, through the bottle's own spout, until it's full or the bottle runs out.
  • Close the cap and check again. Make sure your diesel cap was never opened. Only then start your car.

Find during the second or third stage that the bottle went into the wrong tank? That's where you stop. Leave out step five altogether.

Put AdBlue in the diesel tank in Kings Hedges already?

Then the order of things is short. Do not start your engine. Leave your ignition off as well, because on plenty of diesels switching it on by itself starts the pump. Filling up with diesel won't dilute it: instead, AdBlue drops to the bottom of that tank, just where the fuel is drawn from.

The staff at BP, Esso or any forecourt will normally help pushing the car clear if you ask. If you are on your own drive in Kings Hedges, leave the car where it is.

Where your motor has run by now, pull over safely and turn the car off. On the M11, under 3 miles from Kings Hedges, that means the next exit. Tell us about how far it went: a run towards Cambridge, under 3 miles away, is a bigger job than a short hop across Kings Hedges.

When we arrive in Kings Hedges, what happens?

Our engineers come to your car wherever it has stopped, whether that's outside The Grove Primary School, near Arbury Community Centre or on your own drive. Which liquid got in, the quantity, and if it ran: our technicians ask because the replies decide both work and quote. During the phone call itself, you are told the price — ahead of dispatch.

The fuel system is then purged thoroughly, after that tank is emptied. Not like petrol, AdBlue forms crystals and attacks certain fuel-system metals, and neither washes out unaided. That is why it counts more. After the fuel filter has been cleaned — or replaced, if required — clean diesel goes in, and then the vehicle gets tested. Your engine is fired up next and tested to be sure it runs properly, all before our technicians leave.

Unstarted cars usually mean a half-hour job after arrival. The kit is safe on a busy filling station, and quiet enough for a driveway after dark. Paying happens on the day, not upfront, and you receive the paperwork your insurer asks for: an engineer report and a VAT invoice. Wrong-fuel cover is included in many insurance policies — and so make use of the wait to check yours.
