Preventing AdBlue in a Diesel Tank in Brucefield: Why It Occurs

Pause reading a minute if the diesel tank already has AdBlue in it: ignition off, motor off, and call 0333 366 0103. Caught before the motor runs, it is normally a drain and a thorough flush, done where the car is in Brucefield. Nothing happened yet? Below, the rest of the page explains the why it occurs and the how to prevent it altogether.

Two fillers, two tanks: AdBlue in a diesel vehicle

Many modern diesels around Dunfermline, like those in Brucefield, carry on two fluids; your engine gets only the diesel. AdBlue's own tank holds it, and from there it goes to the exhaust, where spraying cleans the fumes.

There is a filler for every tank. Plenty of motors share a single flap for both, while others put the AdBlue filler to the boot or under the bonnet. The diesel side is topped up at the petrol 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 far less commonly. The error lives in that gap.

How does AdBlue in your diesel tank happen around Brucefield?

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

To start with, the warning. Low AdBlue triggers a message from the vehicle, and running out means limp mode — so a hurried top-up, maybe before work off St Andrews Street, or outside The Olive Tree on the way home after work.

New-to-you vehicles come second, too. Hire cars, new vehicles and company motors place their fillers differently, and habit reaches for the cap used on the old one.

Third, the spout fits: a diesel filler or AdBlue filler, it goes in just as readily, and once the tip starts, no part halts it. The same few seconds decide it, in the middle of Brucefield or out in Garvock Hill.

The AdBlue filler and your diesel filler: telling them apart

Check these first, at a forecourt around Brucefield or a driveway over in Headwell. Seconds, that's all.

  • Blue and lettering: an AdBlue cap is often blue, or says "AdBlue", where a diesel cap usually does not. Go by the cap, not its position.
  • Plenty of cars fit AdBlue the smaller filler of the two.
  • A label inside your fuel flap frequently shows which fuel goes where, on plenty of vehicles. Look for it.
  • Can't see it beside your diesel inlet? Then look beneath the bonnet or in the boot — the handbook will say which.
  • Whoever had it before knows. Check as you pick up a hire car or company car — from Dunfermline City's car park, perhaps — not when the light comes on.

AdBlue top-ups that never reach your diesel tank

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

  • Stop somewhere level, engine off, with time in hand — not rushing on the side of Pitcairn Street.
  • Find the AdBlue filler, read the cap, and speak the word "AdBlue" out loud while you unscrew it. It seems silly. It does the trick.
  • Both behind a single flap? Then confirm the lid on your diesel filler is still closed ahead of lifting the bottle.
  • Finish once that tank fills or the bottle runs dry; until then, tip slowly through the built-in spout.
  • Shut the cap, and look again — confirm the diesel filler remained shut throughout. Only then, start the car.

Spot at step two or three that it has already gone into your diesel side? Then stop right there. Do not go on to step five.

Already put AdBlue in your diesel tank in Brucefield?

The short order of things, beginning with no starting the engine. Leave the ignition off too, because on many diesels switching it on alone starts your fuel pump. Topping up with diesel won't dilute it: rather than mixing, AdBlue drops to the bottom of the tank, right where the fuel is taken from.

The staff at BP, Shell or any forecourt will normally help to push your car clear when you ask. Your own drive around Brucefield is where it stays.

If the motor has already run, stop as soon as it is safe and switch off. The next exit is where to leave if you are on the A823(M), under 3 miles from Brucefield. A short hop across Brucefield is a smaller job than a run towards Dunfermline, under a mile away, so tell us about how far it went.

Our arrival in Brucefield, and what happens next

Our van reaches the vehicle wherever it stopped — your own drive, beside Hospital Hill Gospel Hall, or outside the local primary school. Both the work and our price rest on three replies — which fluid, what amount, and whether it has run — so our engineers ask. No one sets off until you've had the quote over the phone.

The fuel system is then purged thoroughly, after that tank is drained. AdBlue crystallises and is corrosive to some of the metals in a fuel system, and so it does not wash out on its own — which is why the flush matters more here than with petrol. After the fuel filter is cleaned — or renewed, where required — clean diesel is added, and then your car is tested. The engine is started next and tested to be sure it runs properly, all before our technicians go.

Most jobs are finished in about half an hour after our engineers get there, as long as your engine hasn't run — and the pumps our engineers use are fine on a live forecourt yet quiet at night outside a house. Your insurer will ask for an engineer's report and the VAT invoice, and you get both once this job is done. Payment comes on the day, with no money upfront. Misfuelling cover is included in many insurance policies — so use the wait to look at yours.

AdBlue drains across Fife, Brucefield included

Abbey Parks and Gardeners Lands are among the places near Brucefield, a residential suburb, that the same vans cover, throughout KY postcodes. The van gets to you fastest with a postcode starting KY11 4.

Shifting the vehicle is not necessary. A driveway, a lay-by on the way to Rex Park, a side street close to The Hope House Seventh Day Adventist Church: our engineers drain the car where it stands. Awkward to pin down, like the back of The Church of Jesus Christ of Latter-day Saints? Close to a border? Checking beats guessing, and so ring.

In short, for Brucefield people

Tip no AdBlue till you have read the cap. If AdBlue has gone in the diesel tank anyway, leave the vehicle off and call 0333 366 0103. Petrol in Diesel clears it where it sits, anywhere in Fife.
