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

Plenty of modern diesels around High Blantyre, like those in Low Blantyre, carry on two fluids; the motor gets just your 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.

Each tank has its own filler. Some cars keep the AdBlue filler in the boot or under the bonnet; plenty more have the two together behind one flap. Diesel gets filled on every forecourt call-out, week in, week out. Seldom topped up, AdBlue normally goes in from a bottle, poured by a driver who must stop and think what filler to use. The mistake grows in that gap between the two.

AdBlue in the diesel tank around Low Blantyre: how it takes place

It is hardly ever carelessness. Three things tend to line up.

First, the warning. Low AdBlue triggers a warning from the car, and running dry leads to limp mode — so a hurried top-up, maybe before work off Forrest Street, or outside The Old Original Bar on the way home that evening.

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

No part stops the pour after it has started, since a bottle with a spout goes into a diesel filler as readily as an AdBlue one. The bottle fits. Whether it takes place in Blantyre or the middle of Low Blantyre, it's the same few seconds.

Telling the AdBlue filler from your diesel filler

A couple of seconds is all the checks take — so check them before you pour anything, on a driveway in Burnbank or a forecourt in Low Blantyre.

  • Blue and marking: an AdBlue cap is often blue, or says "AdBlue", where a diesel cap usually does not. Trust the cap, not where it sits.
  • Many cars fit AdBlue the smaller filler of the two.
  • A label inside your fuel flap often shows which fuel goes where, on plenty of vehicles. Look for it.
  • Cannot see it next to your diesel filler? In that case check below the bonnet or in your boot — the owner's manual will say where.
  • Picking up a hire or company car, perhaps at the car park at Blantyre? Ask the person who drove it last before you set off, not once the light goes on.

Topping up AdBlue without it reaching the diesel tank

The day the light comes on, anywhere in South Lanarkshire, use this routine.

  • Not in a rush on the side of John Street, not on a slope, not with your motor running: park then switch off first.
  • Daft as it sounds, saying "AdBlue" aloud while you unscrew the cap does the trick — once you have located your filler and read it.
  • Both under a single flap? Then confirm the cap on the diesel filler is still shut ahead of lifting the bottle.
  • Gently is best, through the bottle's own spout, until it is full or the bottle is empty.
  • Only then, start your car: close the cap, check again, and make sure the diesel cap was never opened.

Discover during the second or third step that AdBlue went into the diesel filler? That is where you stop. Stage five stays out.

Already put AdBlue in the diesel tank in Low Blantyre?

Do not start your engine: that's where the short order of things starts. The fuel pump starts on many diesels as soon as your ignition goes on — and so leave it off. Diluting it with extra diesel won't work, because AdBlue sinks to the bottom rather than mixing — and that's where the fuel is drawn from.

The staff at Asda, Shell or another forecourt will normally lend a hand pushing your car away when asked. Your own drive in Low Blantyre is the place it should stay.

Stop as soon as it is safe then switch off, if your engine has already run. Low Blantyre sits under 3 miles from the M74; on it, take the next exit. A short hop across Low Blantyre is a smaller job than a run towards Glasgow, under 10 miles away, so tell us roughly how far it went.

When we arrive in Low Blantyre, what takes place?

We come to the vehicle wherever it has stopped, whether that is outside the local primary school, near KG Stadium or on your own driveway. Those replies determine this work and the quote, so our technicians ask what got in, about how much, and if it's run. You hear that price by phone, before anyone heads out.

Draining your tank comes next, then a full flush of your system. AdBlue crystallises and is corrosive to some of the metals in a fuel system, and so it doesn't wash out on its own — which is why the flush counts more here than with petrol. A test comes last: before that, clean diesel goes in, and the fuel filter is flushed or replaced as needed. Then we fire it up and make sure it runs properly before we leave.

Most jobs are done in roughly half an hour once we arrive, provided your motor hasn't run — and the pumps our technicians use are fine on a live forecourt and quiet after dark beside a house. The insurer usually wants the engineer's report and the VAT invoice, and both are yours once this job is done. Payment comes on the day, with no deposit. Misfuelling cover is part of many insurance policies — and so use the wait to check yours.
