Preventing AdBlue in a Diesel Tank in Airthrey Castle: Why It Occurs
Stop here for a moment when the diesel tank already has AdBlue in it: ignition off, motor off, and call 0333 366 0103. Normally, when the engine has not run, it's emptied and fully purged where the car is in Airthrey Castle. Nothing happened yet? Below, the rest of the page covers the reasons it happens and the ways to prevent it for good.
AdBlue in a diesel vehicle: two tanks, two fillers
Plenty of newer diesels on the roads around Airthrey Castle and Manor Powis carry two liquids, not one. Diesel goes to your motor. Kept in a tank of its own, AdBlue is sprayed into the exhaust stream to clean it.
Separate tanks, different fillers. Under one flap, next to each other: that is the arrangement on a lot of cars. On others, AdBlue's filler sits under the bonnet or in your boot instead. At the petrol pump, your diesel side is topped up constantly. Far less frequently, the AdBlue side gets filled — normally from a bottle, by someone thinking about where it goes. The mistake grows in the gap between them.
How does AdBlue in the diesel tank occur in Airthrey Castle?
It's seldom carelessness. Three things tend to line up.
On a driveway off Hillfoots Road before work, or in the car park outside The Studio on the way home: that is where the hurried top-up happens. Why the rush? As AdBlue gets low the car tells you, and once it's gone, limp mode kicks in.
Unfamiliar motors come next, as well. Rentals, new motors and company vehicles place their fillers differently, and habit goes for the cap used on the old one.
And the bottle fits. A bottle with a spout goes into a diesel filler as easily as an AdBlue one, so nothing stops the pour once it has started. The same few seconds settle it, in the middle of Airthrey Castle or out in Blairlogie.
The AdBlue filler and the diesel filler: telling them apart
A couple of seconds is all these take — so check them before you pour anything, on a driveway in Cornton or a forecourt around Airthrey Castle.
- Colour and marking: an AdBlue cap is regularly blue, or says "AdBlue", where a diesel cap usually does not. Trust the cap, not where it sits.
- Look at the size: the smaller neck is, on plenty of vehicles, the AdBlue one.
- Check inside your fuel flap: many vehicles have a label there saying which fuel goes where.
- The handbook. If your filler isn't by your diesel cap, it is in the boot or under the bonnet, and the handbook says which.
- Collecting a hire or company car, perhaps at the car park outside Bridge of Allan? Check with whoever drove it last before you set off, not once the light comes on.
Topping up AdBlue without it reaching the diesel tank
For the day the light comes on — wherever you are around Stirling — a simple routine to use.
- Stop on level, motor off, with time in hand — not rushing on the side of A91.
- Daft as it sounds, speaking "AdBlue" aloud while you unscrew the cap works — once you've found the filler and read the cap.
- The two under one flap? Then confirm the lid on the diesel side is still closed ahead of raising the bottle.
- Using the bottle's own spout, pour slowly — and stop when it's full or the bottle is empty.
- Only then, start the vehicle: close the cap, check once more, and make sure the diesel cap was never opened.
Spot at stage two or three that it's already gone into the diesel side? Then stop right there. Never go on to stage five.
Put AdBlue in your diesel tank around Airthrey Castle already?
Brief list, then. First: the motor remains unstarted. Leave the ignition off too, because on plenty of diesels switching it on by itself runs your fuel pump. Diluting it with extra diesel won't work, since AdBlue sinks to the bottom rather than blending — and that is where the fuel is drawn from.
At a forecourt — Tesco, Sainsbury's or any other — the attendants will normally help roll your car clear, if you ask. If you're on your own drive around Airthrey Castle, leave the car where it is.
If the motor has already run, stop as soon as it is safe and switch off. On the M9, under 3 miles from Airthrey Castle, that means the next junction. Distance counts — a short hop across Airthrey Castle is a smaller job than heading under 3 miles to Stirling — so tell us about how far it went.
Airthrey Castle: what happens when our technicians arrive
The van reaches the car anywhere it stopped — your own driveway, near Garden of Time Memorial, or outside the local primary school. What liquid got in, the amount, and whether it ran: our technicians ask since the answers decide the work and quote. On the phone call itself, you hear our quote — before dispatch.
Next: a drain, then a full flush of the whole system. Unlike petrol, AdBlue leaves crystals and eats at certain fuel-system metals, and neither washes away by itself. Hence it matters more. The filter is flushed, or replaced where it needs to be; fresh diesel goes in; and your car is tested. Before we go, our technicians fire it up and make sure that it is running properly.
With pumps safe on a busy forecourt and quiet enough to use outside a house at night, most jobs in which the engine hasn't run need roughly half an hour after our engineers are there. Your insurer usually wants the engineer's report and your VAT invoice, and you get both at the end. Payment is on the day, with no money upfront. It's worth looking at your policy while we travel to you: misfuelling cover is included with plenty of policies.
