Corfe Castle: How Does AdBlue End Up in a Diesel Tank, and How Do You Prevent It?
AdBlue already in your diesel tank? In that case set this page down a moment, leave your ignition and engine off, and call 0333 366 0103. A drain and a full flush, carried out right where your vehicle stands in Corfe Castle, is usually what it takes when caught before the motor runs. If you are reading before it has happened, the rest of this page is about why it occurs and how to make sure it does not.
AdBlue in a diesel vehicle, and its separate tank
Plenty of modern diesels on the roads round Corfe Castle and Kingston carry two liquids, not one. Diesel goes to the motor. AdBlue goes to the exhaust, where it is sprayed into the gas to fresh it, and it lives in a tank of its own.
Each tank has its own filler. 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. At the petrol pump, the diesel side gets filled constantly. Much less frequently, the AdBlue side gets topped up — normally from a bottle, by someone thinking about where it goes. That gap is where the error lives.
Corfe Castle: how AdBlue in the diesel tank occurs
Rarely is it carelessness: normally three things coincide.
The warning comes first. As AdBlue runs low your car tells you, and if it runs out completely, your vehicle drops into limp mode. So the top-up is done in a hurry: on a driveway off The Square before work, or in the car park at The Greyhound on the way home.
Next, your hand reaches for the cap it would have used on the old vehicle — because a rental car, a new vehicle or a company car places the fillers where your last one didn't.
No part stops the pour once it has started, because a bottle with a spout goes into a diesel filler as easily as an AdBlue one. The bottle fits. Little Woolgarston or the middle of Corfe Castle: it takes the same few seconds either way.
Telling the AdBlue filler from the diesel filler
Be it a Corfe Castle forecourt or a drive over in Woolgarston, take a few seconds on these before anything goes in.
- Where it sits misleads; the cap does not. AdBlue caps tend to be blue or bear the name "AdBlue" — diesel ones normally don't.
- On many cars, the size gives it away: AdBlue gets the smaller filler neck.
- The flap. Look inside the fuel flap for a label. Many motors say there which fuel goes where.
- In your boot or under the bonnet: that's where the filler is if it's not by the diesel cap, and the handbook tells you which.
- Collecting a hire or company car, say at the car park outside Wareham? Check with the person who drove it last before you set off, not when the light goes on.
Keeping AdBlue out of your diesel tank when you top up
Wherever around Dorset the light comes on, this is a routine for that day.
- Pull in somewhere level, engine off, with time to spare — not rushing on the side of West Street.
- Silly as it sounds, saying "AdBlue" out loud while you unscrew the cap does the trick — once you have located your filler and read the cap.
- The two behind one flap? Then make sure the lid on your diesel filler stays shut before raising the bottle.
- Using the bottle's own spout, tip slowly — and stop when it's full or the bottle is empty.
- Close the cap and check again. Make sure the diesel cap was never opened. Only then start the vehicle.
Discover at the second or third stage that AdBlue went into the diesel tank? That's where you stop. Never go on to stage five.
Corfe Castle: already put AdBlue in the diesel tank?
Brief order, then. Top of that: your motor remains off. Do not switch your ignition on; on many diesels that alone runs the fuel pump. Don't top up with diesel to dilute it: AdBlue doesn't mix with diesel, it sinks to the bottom of your tank, where the fuel is pulled from.
On a forecourt — Murco, BP or another — the staff will usually help push the vehicle away, if you ask. Your own drive around Corfe Castle is where it stays.
Where the engine has run by now, pull over safely then switch the vehicle off. Corfe Castle lies under 50 miles from the M27; there, take the first junction. A short hop across Corfe Castle is a smaller job than a run towards Salisbury, under 50 miles away, so tell us about how far it went.
When our engineers get there around Corfe Castle, what takes place?
By Corfe Castle Church of England Primary School, close to Corfe Castle Town Trust Museum or on your own driveway: wherever your car has stopped, our engineers come to it. What fluid got in, the quantity, and if it ran: we ask because those replies decide the work and price. That quote is given on the call, before any van leaves.
Next: draining, then a thorough flush of the entire system. Not like petrol, AdBlue leaves crystals and attacks certain fuel-system metals, and neither clears out by itself. That is why it counts more. Testing comes last: before that, clean diesel goes in, and your filter is cleaned or replaced if necessary. Your engine is fired up next and tested to be sure it runs correctly, all before our engineers leave.
If the motor hasn't run, the majority of jobs take about half an hour once we're there, using pumps that are fine on a working forecourt and quiet enough to use outside a house at night. You pay on the day, with nothing upfront, and get a VAT invoice and an engineer report for your insurer. Plenty of insurance policies include misfuelling cover, and so it's worth checking yours while we're on the way.
