Llanfihangel-uwch-Gwili: How Does AdBlue End Up in a Diesel Tank, and How Do You Avoid It?
Pause reading for a moment if your diesel tank already has AdBlue in it: ignition off, motor off, and phone 0333 366 0103. A drain and a full flush, carried out right where the vehicle sits in Llanfihangel-uwch-Gwili, is normally all it needs if found before your engine runs. The remainder of this page explains why it occurs and how to make sure it does not — useful if you are reading ahead of time.
AdBlue in a diesel car: two tanks, two fillers
Plenty of modern diesels on the roads about Llanfihangel-uwch-Gwili and Llandilo-yr-ynys carry two liquids, not one. Diesel goes to your engine. Kept in a tank of its own, AdBlue is sprayed into the exhaust gas and cleans it.
Separate tanks, separate fillers. Other motors keep the AdBlue filler in your boot or under the bonnet; plenty of others place both side by side under one flap. At the petrol pump, the diesel side gets filled all the time. Rarely topped up, AdBlue normally goes in out of a bottle, poured by someone who must stop and think what cap it needs. It's in that gap that the slip happens.
AdBlue in your diesel tank in Llanfihangel-uwch-Gwili: how it occurs
Carelessness rarely causes it. What does is three things lining up together.
On a driveway off A40 before work, or in the car park outside the pub in the village heading home: that is where the rushed top-up happens. What is the reason for the rush? As AdBlue gets low the vehicle warns you, and once it's empty, limp mode kicks in.
Then the car is new. A hire car, a new motor or a company car puts the fillers where your last one didn't, and the hand gets to for the cap it would have used on the old one.
A spouted bottle meets no resistance at a diesel filler no more than at an AdBlue one. And so the tip, once started, keeps on. Whether it takes place in Nantgaredig or the middle of Llanfihangel-uwch-Gwili, it's the same few seconds.
How to tell the AdBlue filler from the diesel one
Before you pour anything, whether on a drive in Felingwmuchaf or a forecourt in Llanfihangel-uwch-Gwili, check these. They take a couple of seconds.
- Read the cap instead of going by where it sits: AdBlue caps are commonly blue or marked "AdBlue", and diesel caps normally are not.
- Look at the size: the smaller neck is, on plenty of motors, the AdBlue one.
- Check inside your fuel flap: many motors carry a label there saying which fuel goes where.
- In your boot or under the bonnet: that is where the filler sits if it's not by the diesel cap, and the handbook tells you which.
- Picking up a hire or company car, perhaps at the car park outside Carmarthen? Ask whoever drove it last before you set off, not once the light comes on.
Topping up AdBlue without it reaching your diesel tank
Anywhere across Carmarthenshire the light comes on, here is a routine for that day.
- Park then switch off. Not on a slope, not with the motor running, and not in a rush on the side of Station Road.
- Locate the AdBlue filler, read the cap, and speak the name "AdBlue" aloud as unscrewing it. It seems silly. It does the trick.
- If both sit under one flap, check your diesel cap is still closed before you lift the bottle — then leave the vehicle on.
- Stop when that tank is topped up or the bottle is empty; until then, tip slowly through its own spout.
- Before starting your car, close the cap and check a second time that the diesel cap never opened off.
Find at stage two or three that it has already gone into your diesel side? Then stop just there. Never go on to stage five.
Already put AdBlue in the diesel tank around Llanfihangel-uwch-Gwili?
Don't start your motor: that is how the short order of things begins. Leave your ignition off as well, since on plenty of diesels it by itself starts your fuel pump. Thinning it with more diesel won't work, because AdBlue settles to the bottom instead of mixing — and that's where your fuel is drawn from.
If you are on a forecourt, whether it is the Esso or the Nantycaws, ask the attendants to help push the vehicle clear of the pump. Your own driveway around Llanfihangel-uwch-Gwili is where it should stay.

Our arrival in Llanfihangel-uwch-Gwili, and what takes place next
Our technicians come to your car wherever it has stopped, whether that's outside the local primary school, close to Merlin's Hill Viewing Point or on your own drive. The answers settle this work and our price, and so we ask what went in, about how much, and if it has run. During the call itself, you are told our quote — ahead of dispatch.
Next: draining, then a thorough flush of the whole system. More than with petrol, it counts here: the crystals build up, some metals corrode, and nothing washes away unaided, no matter how long it is left. Once the fuel filter is flushed — or renewed, if needed — fresh diesel goes in, and finally the vehicle is tested. The motor is started next and tested to confirm it runs properly, all before we leave.
If your engine has not run, the majority of 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. No money in advance; you settle up that 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 insurance documents; plenty carry cover for misfuelling.
