AdBlue in a diesel vehicle: two tanks, two fillers

Diesel feeds your motor — but plenty of current diesels seen around Brynmenyn and Sarn carry another liquid as well. AdBlue goes to the exhaust, where it is sprayed into the gas to fresh it, and it lives in a tank of its own.

There is a filler for every tank. On a lot of motors the two sit side by side under the same flap; on others the AdBlue filler is in your boot or under the bonnet. Filling the diesel side at the petrol pump goes on all the time. Rarely topped up, AdBlue usually comes out of a bottle, tipped by someone who must stop and think which filler it needs. Mistakes happen in the gap between the two.

How does AdBlue in your diesel tank take place around Brynmenyn?

It's rarely carelessness. Three things tend to line up.

On a driveway off Bryn Road before work, or in the car park at Fox & Hounds heading home: that is where the hurried top-up happens. Why the rush? As AdBlue runs low the car warns you, and once it is gone, limp mode kicks in.

Then the car is new. A hire car, a new vehicle or a company car puts the fillers where your last one did not, and the hand gets to for the cap it would have used on the old one.

Lastly, the spout fits: a diesel filler or AdBlue filler, it goes in just as easily, and once the tip begins, nothing stops it. Whether it occurs in Abergarw or the middle of Brynmenyn, it is the same few seconds.

Flushing a diesel fuel system after AdBlue, Brynmenyn

Which filler is for AdBlue, and which for diesel?

Before you pour anything, whether on a drive in Cymdda or a forecourt in Brynmenyn, check these. They take a couple of seconds.

  • Position misleads; the cap does not. AdBlue ones are often blue or bear the name "AdBlue" — diesel caps normally do not.
  • On many motors, the size gives it away: AdBlue gets the smaller filler neck.
  • A label inside the fuel flap frequently shows which fuel goes where, on plenty of motors. Check for it.
  • Can't see it beside your diesel filler? In that case look beneath the bonnet or in your boot — the handbook will say where.
  • Picking up a hire or company car, perhaps at the car park outside Tondu? Check with the person who drove the car last before you set off, rather than once the light goes on.

How to top up without AdBlue in your diesel tank

A routine for the day the light comes on, wherever around Bridgend that is.

  • Not in a rush on the side of Abergarw Road, not on a slope, not with your engine running: park then switch off first.
  • Say "AdBlue" out loud as you unscrew the cap, after you find the AdBlue filler and reading it. Daft, yes, yet it works.
  • The two under a single flap? So confirm the cap on the diesel side is still shut ahead of raising the bottle.
  • Slowly is best, through the bottle's own spout, till it's full or the bottle is empty.
  • Close the cap and check a second time. 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 the diesel side, stop there. Do not go on to stage five.

Put AdBlue in the diesel tank around Brynmenyn already?

The short order of things, beginning with not starting the engine. On plenty of diesels the ignition alone runs the fuel pump, and so do not switch it on. Diluting it with more diesel won't work, because AdBlue sinks to the base instead of blending — and that is where the fuel is sucked from.

The attendants at Texaco, Welcome Break or any forecourt will normally lend a hand pushing the car away when you ask. Leave it where it is if you are on your own driveway around Brynmenyn.

Stop as soon as it is safe then switch off, if the motor has already run. The next exit is where to leave if you're on the M4, under 3 miles from Brynmenyn. Tell us roughly how far it went: a run towards Swansea, under 25 miles away, is a bigger job than a short hop across Brynmenyn.

What happens when our technicians arrive in Brynmenyn

We come to the car wherever it has stopped, whether that is outside the local primary school, near Bryn Road Chapel or on your own drive. Which fluid got in, the quantity, and whether it ran: our technicians ask since the replies set the work and quote. Nobody sets off before you have had our quote by phone.

Draining that tank comes next, then a full flush of the fuel system. Much more than with petrol, it counts with AdBlue: the crystals build up, certain metals are attacked, and none of that washes out unaided, however long it sits. Once your filter has been cleaned — or replaced, where required — clean diesel goes in, and then your vehicle gets tested. Then we fire it up and make sure it runs smoothly before we go.

Unrun cars usually need a half-hour job after arrival. The kit is fine on a live forecourt, and quiet enough for a driveway late at night. Payment happens on the day, not upfront, and you receive the paperwork an insurer wants: an engineer's report and a VAT invoice. Many insurance policies include misfuelling cover, and so it's worth checking yours whilst we're on the way.
