AdBlue in a diesel motor: two tanks, two fillers

Diesel feeds your engine — but many newer diesels driven round Burry Port and Llettyrychen carry a second fluid too. AdBlue goes to your exhaust, where it is sprayed into the gas to clean it, and it lives in a tank of its own.

Each tank has its own filler. Under one flap, side by side: that's the arrangement on a lot of cars. Elsewhere, AdBlue's filler sits beneath the bonnet or in the boot instead. The diesel side is filled at the pump all the time. The AdBlue side is topped up far less often, normally from a bottle, and normally by somebody who has to stop and think where it goes. That gap is where the mistake lives.

Burry Port: how AdBlue in your diesel tank happens

Rarely is it carelessness: usually three things coincide.

On a driveway off Old Tramway before work, or in the car park outside Coasting Pilot Inn on the way home: that is where the rushed top-up takes place. What is the reason for the rush? As AdBlue gets low the vehicle warns you, and if it is empty, limp mode follows.

The old car's cap is where your hand goes — yet a rental car, a new vehicle or a company car puts the fillers elsewhere. That's a second factor: a new vehicle.

A spouted bottle finds no resistance at a diesel filler any more than at an AdBlue one. And so the tip, once begun, keeps on. It's seconds, be it out in Dyfatty or right in the heart of Burry Port.

Flushing a diesel fuel system after AdBlue, Burry Port

Which filler is for AdBlue, and which for diesel?

Look at these first, at a forecourt around Burry Port or a driveway over in Furnace. A few seconds, no more.

  • Blue and lettering: an AdBlue cap is often blue, or says "AdBlue", where a diesel cap normally does not. Go by the cap, not where it sits.
  • Look at the size: the smaller neck is, on plenty of motors, the AdBlue one.
  • A label inside your fuel flap often says which fuel goes where, on plenty of cars. Check for it.
  • Cannot see it next to the diesel inlet? Then look below the bonnet or inside the boot — the handbook says which.
  • Ask 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 Pembrey & Burry Port.

Keeping AdBlue out of the diesel tank when you top up

On the day the warning appears — anywhere you are in Carmarthenshire — a simple routine to use.

  • Stop somewhere level, motor off, with time to spare — never rushing on the side of Bridge Street.
  • Daft as it sounds, speaking "AdBlue" aloud while you unscrew the cap does the trick — after you've found your filler and read it.
  • Leave the diesel cap on. If both sit under one flap, check the diesel cap is still closed before you lift the bottle.
  • Stop once that tank is topped up or the bottle is empty; before that, tip gently through its own spout.
  • Only then, start the car: close the cap, check again, and make sure your diesel cap was never opened.

Find during the second or third stage that the bottle went in the wrong tank? That is where you stop. Never go on to stage five.

Burry Port: already put AdBlue in the diesel tank?

Then the order of things is short. Don't start your engine. Don't switch your ignition on; on many diesels that alone runs the fuel pump. Diluting it with extra diesel fails, because AdBlue sinks to the bottom rather than blending — and that is where your fuel is drawn from.

The staff at Chivers Corner, Asda or another forecourt will usually help to push the car away if you ask. On your own drive around Burry Port? So your car stays where it is.

Where your engine has run already, stop safely and switch the car off. On the M4, under 10 miles from Burry Port, that means the next junction. Mileage matters — a short hop across Burry Port makes a smaller job than driving under 15 miles to Swansea — so tell us roughly how far it went.

Burry Port: what happens when our technicians turn up

By the local primary school, near Amelia Earhart or on your own drive: wherever the car has stopped, our technicians come to it. Those replies decide the work and our quote, and so our technicians ask what went in, roughly how much, and if it's run. On the call itself, you are told the quote — ahead of anything else.

After that: a drain, then a full flush of the entire system. More than with petrol, it matters here: the crystals form, certain metals corrode, and none of it clears away on its own, however long it sits. Once the filter has been flushed — or replaced, if needed — fresh diesel is added, and finally the car gets tested. We don't leave until it has been fired up and is running smoothly.

Using pumps safe on a working forecourt and quiet enough to use outside a house at night, most jobs in which your engine hasn't run need roughly half an hour after our engineers arrive. No money in advance; you settle up that day. Afterwards, the VAT invoice and a report from the engineer go to you for your insurer. Misfuelling cover is included in plenty of insurance policies — and so use the wait to look at yours.
