AdBlue in a Diesel Tank in Coalsnaughton: Why It Happens and How to Avoid It
Leave the engine and ignition off then call 0333 366 0103 first — the rest can wait if AdBlue is already in your diesel tank. A drain and a full flush, carried out just where your vehicle sits around Coalsnaughton, is normally all it takes when caught before the engine runs. Nothing happened yet? Below, the rest of the page explains the why it happens and the ways to avoid it for good.
AdBlue in a diesel car: two tanks, two fillers
Many modern diesels on the roads about Coalsnaughton and Fishcross carry two liquids, not one. Diesel goes to the engine. The exhaust, not the motor, is where AdBlue ends up: dosed into the gas to fresh it, from its own tank.
There's a filler on every tank. On a lot of vehicles the two sit side by side under the same flap; on others the AdBlue filler is in your boot or under the bonnet. Filling the diesel side at the petrol pump goes on all the time. Rarely topped up, AdBlue normally goes in from a bottle, poured by someone who must stop and think which cap to use. That gap is where the error lives.
Coalsnaughton: how AdBlue in your diesel tank takes place
It's rarely carelessness. Three things tend to line up.
On a drive off Main Street before work, or in the car park outside Volunteer Arms on the way home: that is where the rushed top-up takes place. Why the rush? As AdBlue runs low the car warns you, and if it's gone, limp mode kicks in.
New-to-you vehicles come next, too. Rentals, new vehicles and company motors put their fillers differently, and the hand goes for the cap used on the old one.
Lastly, the bottle fits: diesel filler or AdBlue one, it slides in just as readily, and after the tip begins, nothing halts it. Devonside or the middle of Coalsnaughton: it takes the same few seconds in both.
Which filler is for AdBlue, and which for diesel?
A couple of seconds is all the checks take — so check them before you tip anything, on a drive in Sauchie or a forecourt in Coalsnaughton.
- Position misleads; the cap does not. AdBlue caps are often blue or carry the name "AdBlue" — diesel caps normally do not.
- The size. On many motors the AdBlue filler neck is the smaller of the two.
- Lift the flap and look for a label — many vehicles show what goes in which inlet just there.
- The handbook. If your filler is not by your diesel cap, it's in your boot or under the bonnet, and the handbook says which.
- Whoever had it before knows. Ask as you collect a hire car or company car — at Alloa's car park, perhaps — not when the light appears.
AdBlue top-ups that never reach your diesel tank
Wherever in Clackmannanshire the light comes on, here is a routine for that day.
- Park and switch off. Not on a slope, not with the motor running, and not in a rush on the side of Ramsay Street.
- Daft as it sounds, saying "AdBlue" out loud while you unscrew the cap works — after you have located the filler and read the cap.
- The diesel cap stays on. When the two sit under a flap, make sure it is shut before lifting the bottle.
- Using the bottle's own spout, pour slowly — and stop when it's full or the bottle is empty.
- Before you start the car, shut the cap and check again that the diesel cap never came off.
Find during the second or third step that AdBlue went in the wrong tank? That is where you stop. Never go on to step five.
Already put AdBlue in your diesel tank in Coalsnaughton?
Then the order of things is short. Don't start your motor. Keep the ignition off as well, since on many diesels it alone runs your fuel pump. Filling up with diesel will not dilute it: rather than mixing, AdBlue drops to the base of the tank, right where the fuel is taken from.
At a forecourt — Morrisons, Asda or another — the staff will normally help push the car clear, when you ask. If you're on your own driveway around Coalsnaughton, leave the car where it is.
If the engine has already run, stop as soon as it is safe then switch off. Leave the M876 — under 10 miles out of Coalsnaughton — at the next exit. Roughly how far did it go? Crossing Coalsnaughton is less work than a trip of under 10 miles towards Stirling, and so tell us.
Our arrival around Coalsnaughton, and what takes place next
Our van comes to your car anywhere it has come to rest — your own drive, near Coalsnaughton Village Hall, or outside the local primary school. We ask what was put in, about how much, and whether it's run, since those replies decide this work and the quote. During the phone call itself, you are told the price — ahead of dispatch.
The fuel system is then cleaned thoroughly, after your tank is cleared. Much more than with petrol, it counts here: the crystals build up, some metals corrode, and none of that clears away unaided, no matter how long it sits. Testing is last: before that, clean diesel goes in, and the filter is cleaned or changed as needed. After that we fire it up and check it runs smoothly before we leave.
Unstarted cars usually mean a half-hour visit after the moment we arrive. The equipment is fine on a live filling station, and hushed enough for a residential street late at night. You pay on the day, with nothing upfront, and get a VAT invoice and an engineer report for your insurer. It's worth checking your policy as the van travels to you: misfuelling cover comes with many policies.
