AdBlue in a diesel vehicle: two tanks, two fillers

Not one fluid but two: that's what plenty of newer diesels near Lee Mount and Ovenden run, with diesel feeding the motor. Your exhaust, not your motor, is where AdBlue goes: dosed into the gas to fresh it, from a separate tank.

Each tank comes with a filler of its own. Plenty of cars have a single flap for the two, while others move the AdBlue filler to your boot or under the bonnet. Topping up your diesel side at the pump happens constantly. Much less commonly, the AdBlue side is topped up — normally from a bottle, by someone working out where it goes. It is in the gap that the slip happens.

Lee Mount: how AdBlue in your diesel tank happens

Three things tend to line up, and carelessness is rarely one of them.

First, the warning. Low AdBlue triggers a message from the vehicle, and letting it run dry means limp mode — hence a rushed top-up, maybe before work off Wheatley Lane, or at Friendly Inn on the way home after work.

Then the vehicle is strange. A hire car, a new car or a company car puts the fillers where your last one didn't, and your hand reaches for the cap it would have used on the old one.

A spout-topped bottle finds no obstacle at a diesel filler any more than at an AdBlue one. So the pour, once begun, keeps on. Whether it occurs in Boothtown or the middle of Lee Mount, it is the same few seconds.

Flushing a diesel fuel system after AdBlue, Lee Mount

Which filler is for AdBlue, and which for diesel?

Before you tip anything, whether on a driveway in Wheatley or a forecourt in Lee Mount, check these. They take a few seconds.

  • Blue and lettering: an AdBlue cap is commonly blue, or says "AdBlue", where a diesel cap usually doesn't. Go by the cap, not where it sits.
  • Look at the size: the smaller filler neck is, on plenty of motors, the AdBlue one.
  • Lift the flap and look for a label — many vehicles show what goes in each inlet right there.
  • In the boot or under the bonnet: that is 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 at Halifax.

AdBlue top-ups that never reach the diesel tank

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

  • Not in a rush on the side of Ovenden Close, not on a slope, not with your motor running: park then switch off first.
  • Say "AdBlue" out loud as you unscrew the cap, after finding the AdBlue filler and reading it. Daft, yes, yet it does the trick.
  • Leave your diesel cap on. If both sit under one flap, check your diesel cap is still closed before you lift the bottle.
  • Stop once your tank fills or the bottle is empty; until then, tip slowly through its built-in spout.
  • Only after that, start your car: close the cap, check a second time, and make sure your diesel cap was never opened.

If at stage two or three you find you have already poured into the diesel side, stop there. Step five is out.

Put AdBlue in the diesel tank in Lee Mount already?

What follows is a short order of things, starting with no starting the motor. On plenty of diesels your ignition alone runs the fuel pump, and so do not switch the car on. AdBlue doesn't mix with diesel — it sinks to the bottom of your tank, where the fuel is pulled from — so don't top up with diesel to dilute it.

On a forecourt — Texaco, Shell or any other — the staff will usually help push the car away, when you ask. If you're on your own drive around Lee Mount, leave the car where it is.

Stop as soon as it is safe and switch off, if the engine has already run. Lee Mount sits under 5 miles from the M62; on it, take the first junction. A short hop across Lee Mount is a smaller job than a run towards Bradford, under 10 miles away, and so tell us about how far it went.

Lee Mount: what takes place when our technicians turn up

Outside Lee Mount Academy, near St Georges Church or on your own drive: wherever the car has stopped, our engineers come to it. Our technicians ask what was put in, about how much, and whether it's run, since those replies settle the work and the price. Nobody heads out before you have had the quote over the phone.

Emptying the tank comes next, then a thorough flush of the fuel system. AdBlue crystallises and is corrosive to some of the metals in a fuel system, so it doesn't wash out on its own — which is why the flush matters more with AdBlue than with petrol. Filter cleaned or, if needed, swapped; clean diesel in; then a test of the car. We don't go until it has been fired up and is running properly.

With pumps fine on a working forecourt and quiet enough to use outside a house at night, most jobs where your motor has not run take roughly half an hour after our engineers arrive. Your insurer will ask for an engineer's report and your VAT invoice, and both are yours at the end. Payment comes on the day, with no deposit. Plenty of insurance policies include misfuelling cover, so it's worth checking yours while we're on the way.
