Why It Occurs and How to Prevent It: AdBlue in a Diesel Tank in Narberth Bridge
If AdBlue is already in your diesel tank, stop reading for a moment: leave the engine and the ignition off and ring 0333 366 0103. Around Narberth Bridge, finding it before the motor turns normally leaves a drain and a full flush where it stands. If you are reading before it has happened, the rest of this page is about why it happens and how to make sure it does not.
AdBlue in a diesel car: two tanks, two fillers
Many newer diesels around Crinow, as well as Narberth Bridge, run on two fluids; the engine takes just the diesel. Its own tank holds it, and from there it is sent to the exhaust, where spraying cleans the fumes.
Every tank comes with one filler of its own. Many of motors have a single flap for the two, while some put the AdBlue filler to the boot or under the bonnet. Filling the diesel side at the pump goes on all the time. Far less frequently, the AdBlue side is filled — normally from a bottle, by a person thinking about where it goes. The mistake grows in the gap between them.
AdBlue in your diesel tank in Narberth Bridge: how it happens
Seldom is it carelessness: normally three things line up.
Haste follows from the warning. The vehicle tells you as AdBlue runs low, and an empty tank puts it into limp mode — so the top-up happens quickly, before work on a drive off Mill Lane, or heading home in the car park at Eagle Inn.
New-to-you cars come next, too. Rentals, new cars and company motors put their fillers differently, and habit goes for the cap used on the old one.
No part stops the pour once 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 settle it, in the middle of Narberth Bridge or out in Narberth.
Telling the AdBlue filler from the diesel filler
Check these first, on a forecourt around Narberth Bridge or a drive out in Woods Cross. A few seconds, that's all.
- Where it sits misleads; the cap does not. AdBlue caps tend to be blue or bear the name "AdBlue" — diesel caps usually don't.
- Plenty of cars fit AdBlue the smaller neck of the two.
- Lift the filler flap and check for a label — plenty of cars mark which goes in which filler right there.
- 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 outside Narberth.
Keeping AdBlue out of the diesel tank when you top up
For the day the warning comes on — anywhere you are around Pembrokeshire — a simple routine to use.
- Park then switch off. Not on a slope, not with your engine running, and not in a rush on the side of Mill Pond Road.
- Say "AdBlue" out loud as you unscrew the cap, after you find the AdBlue filler and reading it. Daft, perhaps, yet it works.
- The two under one flap? Then make sure the lid on your diesel filler is still closed ahead of raising the bottle.
- Slowly is best, through the bottle's own spout, till it's full or the bottle runs out.
- Shut the cap, then look again — making sure the diesel cap stayed closed throughout. After that, start the vehicle.
If at step two or three you find you have already poured into your diesel side, stop there. Don't go on to stage five.
Narberth Bridge: already put AdBlue in the diesel tank?
Brief list, then. First: the motor remains off. The fuel pump starts on many diesels as soon as the ignition goes on — so keep it off. Do not top up with diesel to thin it: AdBlue does not mix with diesel, it sinks to the bottom of your tank, where the fuel is drawn from.
At a forecourt — Texaco, Esso or another — the staff will normally help roll the car away, if you ask. Leave it where it is if you are on your own driveway around Narberth Bridge.
Already run? Stop once it is safe, then turn off. The next junction means where to come off when you are on the M4, under 50 miles from Narberth Bridge. Distance matters — a quick hop across Narberth Bridge is a smaller job than heading under 25 miles to St Davids — so say about how far it went.
Our arrival in Narberth Bridge, and what happens next
Our technicians come to the car wherever it has stopped, whether that's outside the local primary school, close to Narberth Castle or on your own driveway. Which fluid went in, the amount, and if it ran: our technicians ask since those answers decide both work and quote. That price comes over the phone, before any van leaves.
Next: draining, then a thorough flush of the whole system. AdBlue crystallises and is corrosive to some of the metals in a fuel system, so it does not wash out on its own — which is why the flush counts more with AdBlue than with petrol. The fuel filter is flushed, or replaced where it needs to be; clean diesel goes in; and your car is tested. We don't leave until it has been fired up and is running properly.
Most jobs are done in roughly half an hour after we get there, provided the motor has not run — and the pumps our engineers use are safe on a live forecourt yet quiet after dark beside a house. Nothing in advance; you settle up on the day. Afterwards, the VAT invoice and the report from the engineer are handed to you for your insurer. Misfuelling cover is included in many insurance policies — and so make use of the wait to look at yours.
