Rhymney: How Does AdBlue End Up in a Diesel Tank, and How Do You Prevent It?
Stop reading for a moment if the diesel tank already holds AdBlue in it: ignition off, motor off, then call 0333 366 0103. A drain plus a thorough flush, carried out just where your vehicle stands in Rhymney, is usually all it needs when found before your engine runs. Not happened yet? Further down, the page explains the reasons it takes place and the ways to prevent it for good.
Two fillers, two tanks: AdBlue in a diesel motor
Plenty of newer diesels around Princetown, like those in Rhymney, carry on two fluids; your engine gets only the diesel. Your exhaust, not your engine, is where AdBlue ends up: dosed into the gas to fresh it, from a separate tank.
Each tank has its own filler. Under one flap, next to each other: that's the layout on many motors. On others, AdBlue's filler sits under the bonnet or in your boot instead. The diesel side is fuelled at the pump all the time. Much less regularly, the AdBlue side gets topped up — normally from a bottle, by a person thinking about where it goes. It is in the gap that the slip lives.
How AdBlue in your diesel tank happens around Rhymney
Carelessness rarely causes it. Instead is three things lining up at once.
Haste follows from the warning. The car tells you as AdBlue runs low, and an empty tank sends the vehicle into limp mode — so the top-up gets done quickly, before work on a driveway off High Street, or on the way home in the car park at The Royal Arms Hotel.
Then, the hand reaches for the cap it knew on the old car — because a hire car, a new motor or a company car puts the fillers where your last one did not.
And the bottle fits. A bottle with a spout goes into a diesel filler as easily as an AdBlue one, and so nothing stops the pour once it has started. The same few seconds settle it, in the middle of Rhymney or out in Bute Town.
Telling the AdBlue filler from the diesel filler
Before you tip anything, whether on a driveway in Cefn Golau or a forecourt in Rhymney, check these. They take a few seconds.
- The cap. The AdBlue cap is often blue, or marked "AdBlue". Your diesel cap normally isn't. Read it instead of going by where it sits.
- Plenty of vehicles fit AdBlue the smaller filler of the two.
- Check inside your fuel flap: plenty of vehicles have a label there showing which fuel goes where.
- The handbook says where it lives if your filler isn't next to the diesel cap: the boot, or under the bonnet.
- Whoever had it before knows. Check as you pick up a rental or company car — at the nearest station's car park, say — rather than when the warning appears.
AdBlue top-ups that never reach the diesel tank
Anywhere across Caerphilly the light comes on, this is a routine for the day.
- Pull in on level, engine off, with time in hand — not hurried on the side of The Willows.
- Find the AdBlue filler and read the cap. Say "AdBlue" out loud as you unscrew it. It sounds silly and it does the trick.
- The diesel cap remains on. When the two share a flap, make sure it is closed before lifting the bottle.
- Using the bottle's own spout, pour slowly — and stop when it is full or the bottle is empty.
- Before you start the car, close the cap and look a second time that your diesel cap never came off.
If at step two or three you find you have already poured into the diesel side, stop there. Never go on to step five.
Rhymney: already put AdBlue in your diesel tank?
What follows is a short order of things, starting with not starting your motor. Leave your ignition off as well, because on plenty of diesels switching it on alone starts the fuel pump. Filling up with diesel will not dilute it: rather than mixing, AdBlue drops to the bottom of your tank, right where fuel is drawn from.
Ask the attendants to help push your car away from the pump if you're at a forecourt — the Gulf, the Texaco or anywhere else. At home around Rhymney? So your car stays put.
Already started? Pull over when it is safe, then switch off. Rhymney sits under 25 miles from the M4; there, use the first junction. A short hop across Rhymney is a smaller job than a run towards Newport, under 25 miles away, so tell us about how far it went.
When we turn up in Rhymney, what happens?
Our technicians come to the vehicle wherever it has stopped, whether that is outside the local primary school, close to St David's Community Centre or on your own driveway. Our technicians ask what got in, about how much, and if it's run, since those replies settle this work and the quote. You get that quote by phone, before anyone heads out.
After that: a drain, then a thorough flush of the whole system. Not like petrol, AdBlue forms crystals and attacks some fuel-system metals, and neither clears out by itself. That is why it counts more. Once the fuel filter has been cleaned — or replaced, where needed — fresh diesel is added, and finally the vehicle is tested. We don't go until it has been fired up and is running properly.
Unrun vehicles mostly mean a half-hour job after arrival. The equipment is fine on a busy filling station, and quiet enough for a driveway after dark. Payment happens on the day, not upfront, and you are given the documents an insurer asks for: an engineer's report and a VAT invoice. While we travel, take a look at your policy; plenty carry cover for misfuelling.
