Preventing AdBlue in a Diesel Tank in Barnardtown: Why It Occurs
Pause here a minute when the diesel tank already has AdBlue in it: ignition off, motor off, and ring 0333 366 0103. Normally, when the engine hasn't turned, it is emptied and thoroughly flushed where the vehicle is in Barnardtown. Not happened yet? Further down, the page covers the why it happens and the ways to avoid it for good.
AdBlue in a diesel motor, and its separate tank
Plenty of modern diesels in Marshes, like those in Barnardtown, run on two liquids; the engine gets only the diesel. Your exhaust, not your motor, is where AdBlue ends up: dosed into the fumes to fresh them, from its own tank.
Each tank has a filler of its own. On a lot of cars 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 constantly. Rarely topped up, AdBlue usually comes from a bottle, poured by someone who must stop and think which filler it needs. Mistakes happen in the gap between the two.
AdBlue in the diesel tank in Barnardtown: how it happens
Carelessness seldom explains it. Instead is three things coming up at once.
Haste comes from the warning. Your car warns you as AdBlue runs low, and a dry tank puts the vehicle into limp mode — so the top-up gets done quickly, before work on a driveway off Hereford Street, or on the way home in the car park outside Dean Street Social Club.
The old car's cap is where your hand goes — yet a rental car, a new vehicle or a company car keeps the fillers elsewhere. That's a second factor: a strange vehicle.
Third, the bottle goes in: a diesel filler or AdBlue filler, it slides in as easily, and after the tip starts, nothing stops it. East Usk or the middle of Barnardtown: it is the same few seconds in both.
How to tell the AdBlue filler from the diesel one
Look at these first, at a forecourt around Barnardtown or a driveway out in Crindau. Seconds, that's all.
- Position misleads; the cap doesn't. AdBlue caps tend to be blue or bear the word "AdBlue" — diesel caps normally don't.
- The size. On plenty of cars the AdBlue filler neck is the smaller of the two.
- A label inside your fuel flap frequently says which fuel goes where, on many cars. Look for it.
- In your boot or under the bonnet: that is where your filler sits if it is not by the diesel cap, and the handbook says which.
- Check with the person who drove it last — before you leave, not when the light comes on — if you collect a hire or company car from somewhere like the car park outside Newport (South Wales).
Topping up AdBlue without it reaching the diesel tank
For the day the light appears — anywhere you are in Newport — a routine to use.
- Not in a rush on the side of Church Road, not on a slope, not with your motor running: park and switch off first.
- Find the AdBlue filler, read the cap, and speak the word "AdBlue" out loud as unscrewing it. It sounds daft. It works.
- The diesel cap remains on. Where both share a flap, confirm it is closed before the bottle comes up.
- Tip slowly, using the bottle's own spout. Stop when it's full or when the bottle is empty.
- Close the cap and check again. Make sure your diesel cap was never opened. Only then start your car.
Find during the second or third stage that AdBlue went into the wrong filler? That's where you stop. Step five is out.
Put AdBlue in your diesel tank around Barnardtown already?
Then the order of things is short. Do not start the motor. On plenty of diesels your ignition alone runs the fuel pump, so don't switch it on. AdBlue doesn't mix with diesel — it sinks to the bottom of your tank, where the fuel is pulled from — so do not top up with diesel to thin it.
Ask the attendants to help push the vehicle clear of the pump if you're at a forecourt — the Esso, the Shell or somewhere else. If you're on your own driveway around Barnardtown, leave the vehicle where it stands.
If the motor has already run, stop as soon as it is safe and switch off. Come off the M4 — under a mile out of Barnardtown — at the first junction. Distance matters — a short hop across Barnardtown is a smaller job than driving under a mile to Newport — so say about how far it went.
Our arrival in Barnardtown, and what occurs next
Outside the local primary school, close to Ty Derwen or on your own driveway: wherever the car has stopped, we come to it. The replies decide the work and our quote, so we ask what got in, roughly how much, and whether it has run. The quote is given on the call, before any van leaves.
Then the tank is emptied and the fuel system cleaned thoroughly. Unlike petrol, AdBlue leaves crystals and attacks certain fuel-system metals, and neither washes out unaided. That is why it counts more. Filter flushed or, where it must be, swapped; fresh diesel in; then a test of the car. Before we leave, our engineers start it and check that it is running properly.
If your motor has not run, most jobs take about half an hour once we're there, using pumps that are fine on a busy forecourt and quiet enough to use outside a house after dark. You pay on the day, with nothing upfront, and get a VAT invoice and an engineer report for your insurer. Before we get there, have a look at your policy; many include cover for misfuelling.
