AdBlue in a Diesel Tank in Taff Merthyr Garden Village: Why It Happens and How to Stop It
If AdBlue is already in your diesel tank, stop reading for a moment: leave the motor and your ignition off and call 0333 366 0103. Usually, if your engine has not turned, it is emptied and fully purged where the vehicle sits around Taff Merthyr Garden Village. The remainder of this page covers why it takes place and how to make sure it doesn't — useful if you're reading before it has happened.
Two fillers, two tanks: AdBlue in a diesel vehicle
Many modern diesels around Llancaiach, as well as Taff Merthyr Garden Village, run on two liquids; your motor gets just your diesel. AdBlue goes to the exhaust, where it is sprayed into the gas to clean it, and it lives in a tank of its own.
Each tank has its own filler. Other motors keep the AdBlue filler in your boot or under the bonnet; plenty more place both together behind one flap. The diesel side is fuelled at the pump all the time. The AdBlue side is fuelled far less often, usually from a bottle, and usually by a person who has to stop and think where it goes. That gap is where the error lives.
How AdBlue in your diesel tank takes place in Taff Merthyr Garden Village
Carelessness seldom explains it. Instead is three things lining up together.
To start with, the warning. Low AdBlue brings a message from the car, and running out leads to limp mode — hence a rushed top-up, perhaps before work off Maen Gilfach, perhaps outside Ffaldcaiach Inn on the way home that evening.
Next, the hand goes for the cap it would have used on the old motor — because a rental car, a new motor or a company car places the fillers somewhere your last one didn't.
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 tip once it has started. The same few seconds settle it, in the middle of Taff Merthyr Garden Village or out in Trelewis.
The AdBlue filler and your diesel filler: telling them apart
Before you pour anything, whether on a drive in Pentwyn Berthlwyd or a forecourt in Taff Merthyr Garden Village, check these. They take a couple of seconds.
- Check the cap rather than going by where it sits: AdBlue ones are often blue or marked "AdBlue", and diesel caps normally aren't.
- Plenty of cars fit AdBlue the smaller filler of the two.
- The flap. Look inside your fuel flap for a label. Plenty of cars say there which fuel goes where.
- In the boot or under the bonnet: that is where the filler is if it's not by the diesel cap, and the handbook tells you which.
- Ask the person who drove it last — before you leave, not when the light comes on — if you pick up a hire or company car from somewhere like the car park at Quakers Yard.
How to top up without AdBlue in your diesel tank
A routine for the day the light comes on, wherever around Merthyr Tydfil that is.
- Stop on level, motor off, with time to spare — never hurried on the side of Maen Ganol.
- Say "AdBlue" out loud as you unscrew the cap, once you find the AdBlue filler and reading it. Daft, perhaps, yet it works.
- Leave your diesel cap on. If both sit under one flap, check the diesel cap is still closed before you lift the bottle.
- Finish once your tank is topped up or the bottle runs dry; before that, pour gently using its own spout.
- Before you start your car, shut the cap and look a second time that the diesel cap never came off.
Stop there if you find, at step two or three, that you've already poured into the diesel side. Step five is out.
Put AdBlue in the diesel tank around Taff Merthyr Garden Village already?
Short order, then. Top of it: the engine stays unstarted. On plenty of diesels the ignition alone runs the fuel pump, so do not switch the car on. Topping up with diesel will not thin it: instead, AdBlue sinks to the bottom of your tank, right where the fuel is drawn from.
At a forecourt — Gulf Treharris Service Station, Texaco or any other — the staff will usually help roll the car away, if you ask. Leave it where it is if you are on your own drive in Taff Merthyr Garden Village.
Stop as soon as it is safe and switch off, if the motor has already run. On the M4, under 10 miles from Taff Merthyr Garden Village, that means the next junction. Mileage matters — a quick hop across Taff Merthyr Garden Village is a smaller job than driving under 15 miles to Newport — so tell us roughly how far it went.
Our arrival around Taff Merthyr Garden Village, and what occurs next
We come to your car wherever it has stopped, whether that is outside the local primary school, close to Bethania Church Treharris or on your own driveway. We ask what got in, about how much, and if it's run, because the answers determine the work and our price. You get that quote on the phone, before anybody sets off.
Next: draining, then a thorough flush of the entire system. Not like petrol, AdBlue leaves crystals and eats at some fuel-system metals, and neither washes away unaided. That is why it matters more. The fuel filter is flushed, or replaced where it needs to be; fresh diesel goes in; and your car is tested. Your engine is fired up next and tested to be sure it runs smoothly, all before our engineers head off.
If your motor has not run, the majority of jobs take about half an hour once we are there, using pumps that are safe on a busy forecourt and quiet enough to use outside a house after dark. The insurer will ask for the engineer's report and the VAT invoice, and you get both once the job is done. Payment comes on the day, with no money upfront. Many insurance policies include misfuelling cover, so it is worth checking yours while we are on the way.
