Two fillers, two tanks: AdBlue in a diesel car

Many newer diesels on the roads around Kennett End and Moulton carry two liquids, not one. Diesel goes to your engine. AdBlue goes to your exhaust, where it is sprayed into the gas to clean it, and it lives in a tank of its own.

There is a filler on each tank. Plenty of cars have a single flap for both, while some put the AdBlue filler to your boot or under the bonnet. Diesel gets filled on each filling station visit, again and again. Far less often, the AdBlue side is topped up — normally from a bottle, by someone thinking about where it goes. The mistake grows in the gap between them.

Kennett End: how AdBlue in your diesel tank takes place

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

On a driveway off Moulton Avenue before work, or in the car park outside The Bell on the way home: that's where the hurried top-up takes place. Why the rush? As AdBlue gets low the vehicle tells you, and once it's gone, limp mode kicks in.

The old car's filler is where the hand reaches — but a hire car, a new car or a company car keeps the fillers elsewhere. That's the second thing: a new vehicle.

Lastly, the spout goes in: a diesel filler or AdBlue one, it goes in just as readily, and after the pour begins, no part halts it. It's a few seconds, whether out in Kentford or right in the centre of Kennett End.

The AdBlue filler and the diesel filler: telling them apart

Check these before pouring, on a forecourt around Kennett End or a driveway out in Gazeley. A few seconds, no more.

  • Read the cap instead of going by where it sits: AdBlue ones are commonly blue or marked "AdBlue", and diesel ones normally aren't.
  • On plenty of motors, size gives it away: AdBlue gets the smaller filler neck.
  • A label inside your fuel flap often shows which fuel goes where, on plenty of motors. Look for it.
  • In your boot or under the bonnet: that's where your filler sits if it's not by the diesel cap, and the handbook tells you which.
  • The person who drove it last. On a hire or company car collected from somewhere like the car park outside Kennett, ask before you leave, not when the light comes on.

AdBlue top-ups that never reach your diesel tank

Anywhere around Suffolk the light comes on, here is a routine for that day.

  • Stop somewhere level, engine off, with time in hand — never hurried on the side of Old Stable Lane.
  • Find the AdBlue filler, read the cap, and say the name "AdBlue" out loud while you unscrew it. It sounds silly. It does the trick.
  • Leave your diesel cap on. If both sit under one flap, check the diesel cap is still closed before you lift the bottle.
  • Tip slowly, using the bottle's own spout. Stop when it's full or when the bottle is empty.
  • Close the cap and check again. Make sure the diesel cap was never opened. Only then start your car.

Spot at step two or three that it has already gone into the diesel side? Then stop just there. Don't go on to stage five.

Already put AdBlue in the diesel tank around Kennett End?

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

The attendants at BP, Tesco or another forecourt will usually lend a hand to push your car clear when asked. Leave it where it is if you're on your own drive in Kennett End.

Already run? Pull over once it is sensible, then switch off. The next exit means where to come off if you are on the M11, under 25 miles from Kennett End. Tell us roughly how far it went: a run towards Ely, under 15 miles away, is a bigger job than a short hop across Kennett End.

Our arrival in Kennett End, and what occurs next

Anywhere the vehicle has stopped, be it outside Kennett Primary School, beside Kentford and Kennett Village Sign or at home, the van comes to it. Which liquid was put in, the quantity, and if it ran: we ask since the replies decide both work and price. Nobody heads out before you have had our price by phone.

Your system is then flushed thoroughly, once that tank is drained. Unlike petrol, AdBlue forms crystals and attacks certain fuel-system metals, and none of it clears away by itself. Hence it matters more. Testing is last: before that, clean diesel is added, and the fuel filter is cleaned or replaced as needed. The engine is fired up next and tested to be sure it runs correctly, all before our technicians head off.

Unrun cars usually need a half-hour job from the moment we arrive. The kit is safe on a live forecourt, and quiet enough for a driveway late at night. The insurer usually wants the engineer's report and the VAT invoice, and you get both at the end. Payment is on the day, with no deposit. Wrong-fuel cover is part of plenty of insurance policies — so use the wait to look at yours.
