Avoiding AdBlue in a Diesel Tank in Pembroke Dock: Why It Occurs
AdBlue already in the diesel tank? In that case set this page aside for now, leave your ignition and motor off, then phone 0333 366 0103. A drain and a thorough flush, carried out right where your car stands around Pembroke Dock, is usually all it takes when found before your engine runs. If you are reading before it has happened, the rest of this page is about why it takes place and how to make sure it doesn't.
AdBlue in a diesel motor: two tanks, two fillers
Plenty of modern diesels around Pennar, as well as Pembroke Dock, carry on two fluids; the motor takes only your diesel. Its own tank holds it, and from there it is sent to your exhaust, and there a spray treats the fumes.
Every tank comes with one 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 your boot or under the bonnet. Diesel goes in on every forecourt visit, again and again. A driver who has to stop and think where it goes normally tops up the AdBlue side, from a bottle, and much less frequently. It's in that gap that the error happens.
AdBlue in your diesel tank in Pembroke Dock: how it happens
Rarely is it carelessness: normally three things coincide.
First, the warning. Low AdBlue brings a warning from the car, and letting it run out means limp mode — hence a rushed top-up, perhaps before work off Dimond Street, perhaps at Station Inn on the way home after work.
The old car's cap is where your hand reaches — yet a hire car, a new motor or a company car puts the fillers somewhere else. That is a second factor: an unfamiliar vehicle.
Nothing halts 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 a few seconds, whether in Llanion or bang in the heart of Pembroke Dock.
Telling the AdBlue filler from your diesel filler
Before you pour anything, whether on a drive in Llanreath or a forecourt in Pembroke Dock, check these. They take a few seconds.
- Read the cap rather than going by where it sits: AdBlue caps are commonly blue or marked "AdBlue", and diesel caps usually aren't.
- On plenty of cars, the size tells: AdBlue has the smaller filler neck.
- The flap. Look inside your fuel flap for a label. Plenty of motors say there which fuel goes where.
- The handbook shows where it lives if the filler isn't next to your diesel cap: the boot, or under the bonnet.
- The person who drove the car last. On a hire or company car picked up from somewhere like the car park at the nearest station, ask before you leave, not when the light comes on.
AdBlue top-ups that never reach your diesel tank
For the day the light comes on — wherever you are around Pembrokeshire — a routine to use.
- Park and switch off. Not on a slope, not with the engine running, and not in a rush on the side of Laws Street.
- Say "AdBlue" out loud as you unscrew the cap, once you find the AdBlue filler and reading it. Daft, yes, but it does the trick.
- The two under one flap? Then confirm the cap on your diesel side stays shut ahead of raising the bottle.
- Using the bottle's own spout, tip slowly — and stop when it is full or the bottle is empty.
- Shut the cap, then check once more — making sure the diesel cap remained shut the whole time. Only then, start the vehicle.
Spot at step two or three that it's already gone into the diesel side? Then stop just there. Don't go on to stage five.
Put AdBlue in your diesel tank in Pembroke Dock already?
Don't start your engine: that's how the short order of things begins. Leave the ignition off as well, because on many diesels it by itself runs the fuel pump. AdBlue doesn't mix with diesel — it sinks to the bottom of the tank, where your fuel is sucked from — so do not top up with diesel to thin it.
At a forecourt — Asda, Tesco or any other — the attendants will usually help roll the car clear, when you ask. If you are on your own drive around Pembroke Dock, leave the car where it stands.
Already run? Pull over once it is safe, then switch off. Leave the M4 — under 50 miles out of Pembroke Dock — at the first exit. Roughly how far did it go? Crossing Pembroke Dock is smaller work than a run of under 25 miles to St Davids, and so tell us.
What occurs when we get there in Pembroke Dock
Our engineers come to your car wherever it has stopped, whether that is outside the local primary school, close to St. Govan's Shopping Centre or on your own driveway. Those replies determine the work and the quote, and so we ask what was put in, roughly how much, and if it's run. During the call itself, you are told the quote — ahead of anything else.
Then your tank is drained and the system flushed thoroughly. With AdBlue that matters more than with petrol: it crystallises and is corrosive to some of the metals in a fuel system, so it does not wash out on its own. The filter is flushed, or replaced where it needs to be; fresh diesel goes in; and the car is tested. Next we fire it up and confirm it runs correctly before leaving.
With pumps safe on a working forecourt and quiet enough to use outside a house at night, most jobs where the motor has not run take roughly half an hour once we arrive. Paying happens on the day, not upfront, and you are given the paperwork an insurer wants: an engineer's report and a VAT invoice. Misfuelling cover is part of plenty of insurance policies — so make use of the wait to check yours.
