Two fillers, two tanks: AdBlue in a diesel vehicle

Many current diesels on the roads around Branderburgh and Muirton carry two liquids, not one. Diesel goes to the motor. Its own tank holds it, and from there it is sent to the exhaust, and there spraying treats the fumes.

Each tank comes with one filler of its own. Other vehicles put the AdBlue filler in your boot or under the bonnet; a lot more place the two together under one flap. Diesel goes in on every filling station visit, again and again. Rarely filled, AdBlue usually goes in out of a bottle, poured by a driver who must stop and think what filler to use. Mistakes happen in that gap between the two.

Branderburgh: how AdBlue in the diesel tank takes place

Three things tend to come together, and carelessness is rarely one of them.

To start with, the warning. Low AdBlue brings a warning from the car, and running dry means limp mode — hence a hurried top-up, perhaps before work off Queen Street, or at The Steamboat Inn on the way home after work.

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

Third, the bottle goes in: a diesel filler or AdBlue one, it slides in just as readily, and after the tip starts, nothing halts it. The same few seconds settle it, in the middle of Branderburgh or out in Lossiemouth.

How to tell the AdBlue filler from the diesel one

Look at these before pouring, at a forecourt in Branderburgh or a drive out in Windyridge. Seconds, no more.

  • Blue and marking: an AdBlue cap is often blue, or says "AdBlue", where a diesel cap usually does not. Go by the cap, not its position.
  • Check the size: the smaller neck is, on many cars, the AdBlue one.
  • Look inside the fuel flap: many motors carry a label there saying which fuel goes where.
  • The handbook says where it lives if your filler is not next to your diesel cap: the boot, or under the bonnet.
  • Ask the person who drove it last — before you leave, not when the light comes on — if you pick up a hire or company car from somewhere like the car park at Elgin.

Topping up AdBlue without it reaching the diesel tank

For the day the light comes on — anywhere it is across Moray — a simple routine to use.

  • Park and switch off. Not on a slope, not with your motor running, and not in a rush on the side of Argyle Street.
  • Silly as it sounds, speaking "AdBlue" aloud as you unscrew the cap does the trick — once you've located your filler and read it.
  • 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 a second time. Make sure your diesel cap was never opened. Only then start the car.

If at stage two or three you find you have already poured into your diesel side, stop there. Skip stage five altogether.

Put AdBlue in your diesel tank around Branderburgh already?

Brief list, then. First: your motor remains unstarted. The fuel pump starts on plenty of diesels as soon as your ignition is switched on — so leave it off. Topping up with diesel will not weaken it: instead, AdBlue drops to the base of your tank, just where the fuel is taken from.

If you're at a forecourt, whether it's the the nearest petrol station or the another forecourt nearby, ask the staff to help push the vehicle clear of the pump. Leave it where it is if you are on your own drive in Branderburgh.

If your motor has already run, stop as soon as it is safe then switch off. The next junction means the place to leave if you are on the M90, over 50 miles from Branderburgh. Tell us about how far it went: a run towards Inverness, under 50 miles away, is a bigger job than a short hop across Branderburgh.

When our engineers turn up in Branderburgh, what takes place?

By the local primary school, close to James Square Plough or on your own driveway: wherever the vehicle has stopped, our engineers come to it. Both the work and our price depend on three replies — which fluid, which amount, and whether it's run — so our engineers ask. You get that price on the phone, before anyone sets off.

After that: draining, then a thorough flush of the whole system. With AdBlue that matters more than with petrol: it crystallises and is corrosive to some of the metals in a fuel system, so it does not wash out on its own. The fuel filter is flushed, or replaced where it needs to be; clean diesel goes in; and the vehicle is tested. We don't go until it has been started and is running correctly.

Using pumps fine on a working forecourt and quiet enough to use outside a house at night, most jobs in which the engine has not run need roughly half an hour once our technicians arrive. You pay on the day, with nothing upfront, and get a VAT invoice and an engineer report for your insurer. Many insurance policies include misfuelling cover, and so it's worth checking yours whilst we're on the way.
