Avoiding AdBlue in a Diesel Tank in Caer-bont: Why It Occurs
Keep your motor and ignition off and phone 0333 366 0103 first — reading can wait if AdBlue is already in the diesel tank. Normally, if your motor hasn't run, it is emptied and fully flushed where the car is in Caer-bont. Not happened yet? Below, the rest of the page explains the why it occurs and the ways to avoid it for good.
AdBlue in a diesel vehicle: two tanks, two fillers
Plenty of modern diesels on the roads round Caer-bont and Caer-Lan carry two liquids, not one. Diesel goes to your motor. 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 comes with a filler of its own. 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. Diesel goes in at each forecourt call-out, again and again. Seldom topped up, AdBlue normally goes in out of a bottle, tipped by a driver who has to stop and think which filler to use. That gap is where the error lives.
How does AdBlue in the diesel tank occur in Caer-bont?
Three things tend to come together, and carelessness is rarely one of them.
Hurry comes from the warning. The vehicle warns you as AdBlue runs low, and an empty tank sends it into limp mode — so the top-up gets done quickly, before work on a driveway off Brecon Road, or on the way home in the car park outside Penrhos Social Club.
New-to-you motors are second, as well. Rentals, new motors and company cars put their fillers in new places, and the hand reaches for the cap used on the old one.
Nothing stops the tip once it has started, because a bottle with a spout goes into a diesel filler as readily as an AdBlue one. The bottle fits. It takes seconds, whether in Ynys-uchaf or bang in the heart of Caer-bont.
Which filler is for AdBlue, and which for diesel?
Check these first, at a forecourt in Caer-bont or a driveway out in Cwmgiedd. Seconds, no more.
- Position can mislead; the cap doesn't. AdBlue ones tend to be blue or carry the word "AdBlue" — diesel caps normally do not.
- The size. On plenty of motors the AdBlue filler neck is the smaller of the two.
- A label inside the fuel flap often shows which fuel goes where, on plenty of vehicles. Check for it.
- The handbook says where it is if your filler is not next to your diesel cap: the boot, or under the bonnet.
- Collecting a hire or company car, say at the car park at Neath? Ask whoever drove the vehicle last before leaving, rather than when the light goes on.
Keeping AdBlue out of your diesel tank when you top up
Anywhere across Powys the light comes on, this is a routine for that day.
- Pull in somewhere level, engine off, with time to spare — not rushing on the side of A4067.
- Find the AdBlue filler and read the cap. Say "AdBlue" out loud as you unscrew it. It sounds daft and it does the trick.
- Leave the diesel cap on. If both sit under one flap, check your diesel cap is still closed before you lift the bottle.
- Finish once that tank fills or the bottle is empty; before that, pour gently using the own spout.
- Close the cap and check again. Make sure the diesel cap was never opened. Only then start your car.
If at step two or three you find you have already poured into your diesel side, stop there. Never carry on to step five.
Already put AdBlue in the diesel tank around Caer-bont?
Don't start your motor: that is where the short order of things begins. On many diesels the ignition alone runs the fuel pump, and so don't switch the car on. Don't top up with diesel to thin it: AdBlue does not mix with diesel, it sinks to the bottom of your tank, where your fuel is drawn from.
If you are on a forecourt, whether it is the Murco or the Tesco, ask the attendants to help roll the vehicle away from the petrol pump. If you are on your own driveway around Caer-bont, leave it where it stands.
Where your engine has been run already, stop safely then turn the vehicle off. Leave the M4 — under 15 miles out of Caer-bont — at the next exit. Distance counts — a quick hop across Caer-bont makes a smaller job than driving under 15 miles to Swansea — so say roughly how far it went.
What occurs when our technicians arrive around Caer-bont
We come to your car wherever it has stopped, whether that is outside the local primary school, near Ystradgynlais Community Centre or on your own driveway. Both the work and the quote rest on three answers — which fluid, what amount, and whether it has run — so our technicians ask. No one heads out before you have had the price over the phone.
Your system is then flushed thoroughly, after your tank is drained. More than with petrol, it matters here: the crystals build up, some metals corrode, and none of that clears out unaided, no matter how long it is left. Once the filter is cleaned — or replaced, if needed — fresh diesel is added, and then your vehicle gets tested. We do not go until it has been fired up and is running correctly.
With pumps safe on a busy forecourt and quiet enough for use outside a house at night, most jobs in which the engine has not run need roughly half an hour once our engineers are there. 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 insurance documents; plenty carry cover for misfuelling.
