AdBlue in a Diesel Tank in Ynysybwl: How It Happens and How to Avoid It
AdBlue already in the diesel tank? In that case put this page down for now, leave the ignition and engine off, then phone 0333 366 0103. Usually, when the motor hasn't run, it is drained and fully purged where the vehicle is in Ynysybwl. If you are reading before it has happened, the remainder 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 newer diesels in Coed y Cwm, as well as Ynysybwl, run on two liquids; the motor takes only the diesel. Kept in a tank of its own, AdBlue is fed into the exhaust gas to clean it.
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 the boot or under the bonnet. At the petrol pump, the diesel side is topped up all the time. Far less commonly, the AdBlue side is filled — mostly from a bottle, by a person thinking about where it goes. The error lives in that gap.
AdBlue in the diesel tank around Ynysybwl: how it takes place
Seldom is it carelessness: usually three things line up.
Haste follows from the warning. Your 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 drive off High Street, or on the way home in the car park outside The Roberttown.
Next, the hand reaches for the cap it knew on the old motor — because a rental car, a new motor or a company car places the fillers somewhere your last one did not.
Nothing halts the tip after it has started, since a bottle with a spout goes into a diesel filler as easily as an AdBlue one. The bottle fits. The same few seconds decide it, in the middle of Ynysybwl or out in Buarth-y-Capel.
The AdBlue filler and the diesel filler: telling them apart
Be it a Ynysybwl forecourt or a drive over in Glyncoch, spend a couple of seconds on these before anything is poured in.
- The cap. The AdBlue cap is frequently blue, or marked "AdBlue". The diesel cap normally isn't. Read it instead of going by where it sits.
- The size. On plenty of vehicles the AdBlue filler neck is the smaller of the two.
- The flap. Look inside your fuel flap for a label. Plenty of motors say there which fuel goes where.
- In your boot or under the bonnet: that's where your filler sits 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 at Abercynon? Check with whoever drove the vehicle last before you set off, rather than once the light comes on.
AdBlue top-ups that never reach the diesel tank
For the day the warning comes on — wherever you are across Rhondda Cynon Taf — a simple routine to follow.
- Turn off after you park — flat ground, motor off, and not in a rush by Windsor Place on the verge.
- Daft as it sounds, saying "AdBlue" aloud while you unscrew the cap does the trick — once you have found the filler and read it.
- Leave your diesel cap on. If both sit under one flap, check your diesel cap is still closed before you lift the bottle.
- Finish when your tank is topped up or the bottle is empty; until then, pour slowly through its built-in spout.
- Only after that, start your car: close the cap, check once more, and make sure the diesel cap was never opened.
Find at step two or three that it's already gone into the diesel side? So stop right there. Stage five is out.
AdBlue in the diesel tank already, in Ynysybwl?
Then the order of things is short. Don't start the motor. Don't switch your ignition on; on plenty of diesels that alone runs the fuel pump. Diluting it with extra diesel won't work, because AdBlue sinks to the base rather than blending — and that's where your fuel is pulled from.
The attendants at Texaco, Asda or any forecourt will usually help to push your car away when asked. If you're on your own driveway around Ynysybwl, leave the car where it stands.
Already started? Pull over once it's sensible, then switch off. Ynysybwl lies under 10 miles from the M4; on it, take the first exit. Tell us about how far it went: a run towards Cardiff, under 15 miles away, is a bigger job than a short hop across Ynysybwl.
What happens when we turn up around Ynysybwl
We come to your car wherever it has stopped, whether that's outside the local primary school, near Ynysywbl Community Centre or on your own drive. We ask what went in, roughly how much, and whether it has run, because those answers settle the work and our quote. That quote is given over the phone, before any van leaves.
Then that tank is cleared and your system purged thoroughly. Unlike petrol, AdBlue leaves crystals and eats at certain fuel-system metals, and neither washes away by itself. Hence it counts more. After the filter is flushed — or replaced, if required — clean diesel goes in, and then your car is tested. Your engine is started next and checked to make sure it runs correctly, all before our technicians go.
Using pumps safe on a working forecourt and quiet enough for use outside a house at night, most jobs in which your engine hasn't run take roughly half an hour after our engineers arrive. Nothing upfront; you settle up on the day. At the end, the VAT invoice and a report from the engineer are handed to you for your insurer. While we travel, have a look at your policy; many include cover for misfuelling.
