AdBlue in a diesel car: two tanks, two fillers

Many newer diesels around Aspley, as well as Bobbers Mill, carry on two fluids; your motor takes just the diesel. 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 for each tank. Under one flap, side by side: that's the layout on a lot of motors. On others, AdBlue's filler is under the bonnet or in the boot instead. The diesel side is topped up at the petrol pump all the time. The AdBlue side is fuelled far less regularly, normally from a bottle, and usually by somebody who has to stop and think where it goes. Mistakes happen in that gap between the two.

How AdBlue in the diesel tank happens around Bobbers Mill

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

First, the warning. Low AdBlue brings a warning from the car, and running dry means limp mode — hence a rushed top-up, maybe before work off Bobbers Mill Bridge, or at Nags Head on the way home that evening.

Then, the hand reaches for the cap it knew on the old motor — because a hire car, a new motor or a company car places the fillers somewhere your last one didn't.

Nothing stops the tip once it has started, because a bottle with a spout goes into a diesel filler as easily as an AdBlue one. The bottle fits. The same few seconds decide it, in the middle of Bobbers Mill or out in Whitemoor.

How to tell the AdBlue filler from the diesel one

Check these first, at a forecourt in Bobbers Mill or a drive out in Forest Fields. A few seconds, that's all.

  • Read the cap rather than going by position: AdBlue ones are frequently blue or marked "AdBlue", and diesel caps normally are not.
  • On many motors, size tells: AdBlue gets the smaller filler neck.
  • A label inside your fuel flap frequently says which fuel goes where, on many vehicles. Check for it.
  • Can't find it next to your diesel filler? In that case check below the bonnet or in your boot — the handbook will say which.
  • Picking up a hire or company car, perhaps at the car park outside Nottingham? Check with whoever drove the car last before leaving, not when the light goes on.

Topping up AdBlue without it reaching the diesel tank

A routine for the day the light comes on, wherever in Nottinghamshire that is.

  • Switch off once parked — level ground, engine off, and not in a rush beside Nuthall Road at the roadside.
  • Locate the AdBlue filler, read the cap, and say the word "AdBlue" out loud while unscrewing it. It seems silly. It works.
  • If both sit under one flap, check the diesel cap is still closed before you lift the bottle — and leave the car on.
  • Using the bottle's own spout, pour slowly — and stop when it is full or the bottle is empty.
  • Before you start the car, close the cap and check a second time that your diesel cap never opened off.

If at stage two or three you find you have already poured into the diesel side, stop there. Never carry on to step five.

Put AdBlue in the diesel tank in Bobbers Mill already?

The short order of things, beginning with no starting your motor. The fuel pump starts on plenty of diesels the moment the ignition is switched on — so keep it off. Don't top up with diesel to dilute it: AdBlue doesn't mix with diesel, it sinks to the bottom of the tank, where the fuel is sucked from.

If you are on a forecourt, whether it is the Asda or the Esso, ask the staff to help push the car clear of the pump. On your own drive around Bobbers Mill? Then the vehicle stays put.

Where the engine has been run already, pull over safely then switch it off. The next exit means where to come off if you're on the M1, under 3 miles from Bobbers Mill. About how far did it go? Crossing Bobbers Mill is smaller a job than a trip of under 3 miles towards Nottingham, so tell us.

Our arrival in Bobbers Mill, and what takes place next

By Berridge Primary and Nursery School, close to Lutheran Church or on your own drive: wherever the car has stopped, our engineers come to it. Our engineers ask what was put in, about how much, and whether it's run, since the answers settle this work and the quote. The quote is given over the phone, before any van leaves.

Next: a drain, then a full flush of the entire system. With AdBlue that matters more than with petrol: it crystallises and is corrosive to some of the metals in a fuel system, and so it doesn't wash out on its own. Your filter is cleaned, or replaced where it needs to be; clean diesel goes in; and your car is tested. We don't leave until it has been started and is running correctly.

Unstarted vehicles mostly mean a half-hour visit from arrival. The equipment is safe on a live filling station, and hushed enough for a driveway after dark. Nothing in advance; you settle up that day. Afterwards, the VAT invoice and a report from the engineer are handed to you for the insurer. Before we get there, take a look at your insurance documents; plenty carry cover for misfuelling.
