Two fillers, two tanks: AdBlue in a diesel motor

Diesel feeds your motor — yet many newer diesels driven about Carnwadric and Mansewood carry a second fluid as well. Your exhaust, not the motor, is where AdBlue ends up: sprayed into the gas to fresh it, from a separate tank.

Separate tanks, separate fillers. Many of cars share a single flap for the two, whereas others move the AdBlue filler to the boot or under the bonnet. The diesel side is fuelled at the pump all the time. Someone who has to stop and work out where it goes usually tops up the AdBlue side, from a bottle, and much less commonly. That gap is where the mistake lives.

Carnwadric: how AdBlue in your diesel tank happens

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

On a driveway off Kiloran Street before work, or in the car park at the pub in the village heading home: that is where the rushed top-up takes place. What is the reason for the rush? As AdBlue runs low your car tells you, and if it is gone, limp mode kicks in.

Next, your hand goes for the cap it would have used on the old car — because a rental car, a new car or a company car places the fillers where your last one didn't.

And the bottle fits. A bottle with a spout goes into a diesel filler as easily as an AdBlue one, and so nothing stops the tip once it has started. Whether it occurs in Kennishead or the middle of Carnwadric, it is the same few seconds.

Flushing a diesel fuel system after AdBlue, Carnwadric

Which filler is for AdBlue, and which for diesel?

A few seconds is all the checks take — so run through them before you pour anything, on a driveway in Jenny Lind or a forecourt in Carnwadric.

  • The cap. The AdBlue cap is regularly blue, or marked "AdBlue". The 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.
  • Lift the flap and look for a label — many motors mark which goes in each filler right there.
  • Cannot find it beside the diesel inlet? In that case check below the bonnet or inside the boot — the handbook will say which.
  • The person who drove it last. On a hire or company car picked up from somewhere like the car park outside Kennishead, ask before you leave, not when the light comes on.

AdBlue top-ups that never reach your diesel tank

On the day the warning appears — wherever you are across Glasgow City — a routine to follow.

  • Not in a rush on the side of Bangorshill Street, not on a slope, not with the engine running: park and switch off first.
  • Daft as it sounds, speaking "AdBlue" aloud as you unscrew the cap does the trick — once you have found your filler and read the cap.
  • If both sit under one flap, check your diesel cap is still closed before you lift the bottle — then leave the vehicle on.
  • Using the bottle's own spout, pour slowly — and stop when it is full or the bottle is empty.
  • Only then, start your car: close the cap, check a second time, and make sure the diesel cap was never opened.

Spot at stage two or three that it's already gone into the diesel side? So stop right there. Step five stays out.

Already put AdBlue in the diesel tank around Carnwadric?

Do not start your engine: that is where the short order of things starts. On many diesels the ignition alone runs the fuel pump, and so do not switch the vehicle on. Don't top up with diesel to thin it: AdBlue doesn't mix with diesel, it sinks to the bottom of your tank, where your fuel is pulled from.

At a forecourt — BP, Shell or another — the staff will normally help roll your car clear, if you ask. At home around Carnwadric? So your car stays where it is.

Stop as soon as it is safe then switch off, if the engine has already run. The next junction is where to leave if you are on the M77, under a mile from Carnwadric. Distance counts — a quick hop across Carnwadric is a smaller job than driving under 5 miles to Glasgow — so tell us roughly how far it went.

When our engineers get there around Carnwadric, what occurs?

Outside the local primary school, close to Carnwadric Church or on your own drive: wherever your car has stopped, we come to it. Both the work and the quote rest on three replies — what liquid, what amount, and if it has run — so our technicians ask. That quote is given over the phone, before any van leaves.

Then the tank is drained and your system flushed thoroughly. 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 that counts more here than with petrol. After the filter is flushed — or replaced, where needed — clean diesel goes in, and finally the vehicle gets tested. The engine is started next and tested to make sure it runs correctly, all before our engineers go.

Using pumps safe on a working forecourt and quiet enough for use outside a house at night, most jobs in which the motor has not run need roughly half an hour once our technicians are there. The insurer usually wants an engineer's report and your VAT invoice, and both are yours once the job is done. Payment comes on the day, with no money upfront. Wrong-fuel cover is part of many insurance policies — so make use of the wait to check yours.
