AdBlue in a Diesel Tank in Bridgeness: Why It Happens and How to Prevent It

In Bridgeness, finding it before your engine turns normally leaves a drain and a full flush on the spot. Not happened yet?

Why does AdBlue in a diesel car need its own filler?

Not one fluid but two: that's how many modern diesels near Bridgeness and Grahamsdyke run, with diesel for your motor. Your exhaust, not the motor, is where AdBlue goes: sprayed into the fumes to fresh it, from its own tank.

There's a filler for every tank. Plenty of motors have a single flap for the two, whereas others move the AdBlue filler to the boot or under the bonnet. Topping up your diesel side at the pump goes on all the time. Rarely topped up, AdBlue usually comes out of a bottle, poured by a driver who must stop and think what filler to use. It is in the gap that the error lives.

AdBlue in the diesel tank in Bridgeness: how it takes place

Rarely is it carelessness: usually three things coincide.

The warning comes first. As AdBlue runs low your car tells you, and if it runs out altogether, the car goes into limp mode. So the top-up is done in a hurry: on a drive off Tower Gardens before work, or in the car park outside The Anchor Tavern on the way home.

Unfamiliar motors come second, as well. Hire cars, new cars and company vehicles place their fillers differently, and the hand goes for the cap used on the old one.

A spouted bottle finds no resistance at a diesel filler any more than at an AdBlue one. And so the tip, after begun, carries on. Whether it occurs in Grangepans or the middle of Bridgeness, it's the same few seconds.

How to tell the AdBlue filler from the diesel one

Check these before pouring, on a forecourt around Bridgeness or a driveway out in Boness. Seconds, that's all.

  • The cap. The AdBlue cap is frequently blue, or marked "AdBlue". Your diesel cap usually isn't. Read it rather than going by position.
  • Check the size: the smaller neck is, on plenty of cars, the AdBlue one.
  • The flap. Look inside the fuel flap for a label. Many vehicles say there which fuel goes where.
  • Can't find it next to the diesel inlet? Then check below the bonnet or inside your boot — the handbook says which.
  • The person who drove the vehicle last. On a hire or company car picked up from somewhere like the car park outside Linlithgow, ask before you leave, not when the light comes on.

Topping up AdBlue without it reaching the diesel tank

Wherever around Falkirk the light comes on, this is a routine for the day.

  • Park and switch off. Not on a slope, not with the engine running, and not in a rush on the side of Bridgeness Lane.
  • Silly as it sounds, saying "AdBlue" aloud while you unscrew the cap works — once you have located the filler and read it.
  • The two under a single flap? So confirm the cap on your diesel side is still closed before lifting the bottle.
  • Gently is best, through the bottle's own spout, until it is full or the bottle runs out.
  • Before starting your car, close the cap and check again that your diesel cap never came off.

Stop there if you find, at step two or three, that you've already poured into your diesel side. Do not go on to stage five.

Already put AdBlue in the diesel tank around Bridgeness?

What follows is a short order of things, beginning with not starting your motor. The fuel pump runs on plenty of diesels the moment the ignition goes on — and so leave it off. Filling up with diesel won't dilute it: rather than mixing, AdBlue sinks to the base of that tank, just where the fuel is drawn from.

If you are on a forecourt, whether it is the Hastons of Bo'ness or the Esso, ask the staff to help roll the car clear of the petrol pump. If you're on your own drive around Bridgeness, leave the car where it stands.

If the engine has already run, stop as soon as it is safe and switch off. On the M9, under 3 miles from Bridgeness, that means the next exit. About how far did it go? Hopping across Bridgeness is less a job than a run of under 10 miles towards Dunfermline, so say.

Our arrival around Bridgeness, and what happens next

Our engineers come to your car wherever it has stopped, whether that is outside the local primary school, close to Antonine Wall Marker or on your own drive. Both the work and our quote depend on three replies — which fluid, what amount, and if it's run — so we ask. No one sets off until you've heard our price over the phone.

Then that tank is emptied and the system flushed thoroughly. Unlike petrol, AdBlue leaves crystals and eats at certain fuel-system metals, and none of it washes out by itself. That is why it counts more. After your filter has been flushed — or renewed, where needed — fresh diesel is added, and then your vehicle is tested. The engine is fired up next and checked to make sure it runs correctly, all before we go.

If your engine has not run, the majority of jobs take about half an hour once we are there, using pumps that are safe on a working forecourt and quiet enough to use outside a house after dark. You pay on the day, with nothing upfront, and get a VAT invoice and an engineer report for your insurer. While we travel, have a look at your insurance documents; many include cover for misfuelling.
