AdBlue in a diesel vehicle, and its separate tank

Diesel feeds the engine — but plenty of current diesels seen around Muiredge and Cameron carry another liquid as well. Stored in a tank of its own, AdBlue is fed into the exhaust stream and cleans it.

Different tanks, different fillers. Some cars keep the AdBlue filler in your boot or under the bonnet; a lot more have both side by side behind one flap. The diesel side is topped up at the petrol pump all the time. The AdBlue side is topped up far less commonly, normally from a bottle, and usually by a person who has to stop and think where it goes. The error lives in that gap.

Muiredge: how AdBlue in the diesel tank happens

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

The warning comes first. As AdBlue runs low your car tells you, and if it runs out completely, the vehicle drops into limp mode. So the top-up is done in a hurry: on a drive off Thrush Avenue before work, or in the car park outside Buck and Hind on the way home.

The old car's filler is where the hand goes — yet a hire car, a new vehicle or a company car keeps the fillers somewhere else. That's a second factor: a new vehicle.

A spouted bottle finds no resistance at a diesel filler any more than at an AdBlue one. And so the pour, once begun, carries on. It takes a few seconds, whether out in Denbeath or bang in the centre of Muiredge.

The AdBlue filler and your diesel filler: telling them apart

A few seconds is all the checks take — so check them before you tip anything, on a drive in Cameron Bridge or a forecourt in Muiredge.

  • The cap. The AdBlue cap is frequently blue, or marked "AdBlue". The diesel cap usually is not. Read it instead of going by where it sits.
  • The size. On many motors the AdBlue filler neck is the smaller of the two.
  • A label inside the fuel flap often shows which fuel goes where, on plenty of vehicles. Check for it.
  • In your boot or under the bonnet: that's where your filler sits if it's not by the diesel cap, and the handbook tells you which.
  • Ask the person who drove it last — before you leave, not when the light comes on — when you pick up a hire or company car from somewhere like the car park at Cameron Bridge.

AdBlue top-ups that never reach your diesel tank

Wherever around Fife the light comes on, here is a routine for the day.

  • Park then switch off. Not on a slope, not with the motor running, and not in a rush on the side of Wren Street.
  • Find the AdBlue filler, check the cap, and speak the name "AdBlue" aloud while unscrewing it. It seems silly. It does the trick.
  • If both sit under one flap, check the diesel cap is still closed before you lift the bottle — then leave the car on.
  • Tip slowly, using the bottle's own spout. Stop when it's full or when the bottle is empty.
  • Only after that, start your car: close the cap, check again, and make sure the diesel cap was never opened.

Stop there if you find, at stage two or three, that you've already poured into the diesel side. Leave out step five altogether.

Already put AdBlue in the diesel tank in Muiredge?

Brief list, then. Top of it: the engine stays unstarted. On many diesels the ignition alone runs the fuel pump, and so don't switch the car on. Thinning it with extra diesel won't work, since AdBlue sinks to the base rather than blending — and that's where the fuel is sucked from.

Ask the attendants to help push your car away from the petrol pump if you're on a forecourt — the BP, the Shell or somewhere else. On your own drive around Muiredge? Then the car remains where it is.

When the motor has run by now, pull over safely then switch the car off. Come off the M90 — under 15 miles out of Muiredge — at the first exit. A short hop across Muiredge is a smaller job than a run towards Edinburgh, under 25 miles away, and so tell us about how far it went.

Our arrival around Muiredge, and what occurs next

Wherever your car has stopped, be it by the local primary school, beside Robert Dunsire VC Memorial or on your own drive, the van travels to it. Those answers decide this work and our price, and so our technicians ask what went in, about how much, and whether it has run. You get that price on the phone, before anybody sets off.

The system is then cleaned thoroughly, once that tank is cleared. Much more than with petrol, it matters with AdBlue: crystals form, certain metals corrode, and nothing clears out unaided, however long it sits. Once the fuel filter has been cleaned — or renewed, where needed — fresh diesel is added, and finally your vehicle gets tested. Before we go, our engineers start it and confirm that it is running correctly.

Most jobs are finished in about half an hour once our engineers arrive, as long as your motor hasn't run — and the pumps we use are fine on a live forecourt yet quiet after dark beside a house. No money in advance; you settle up on the day. Afterwards, the VAT invoice and a report from the engineer are handed to you for your insurer. Many insurance policies include misfuelling cover, and so it is worth checking yours while we're on the way.
