AdBlue in a diesel motor: two tanks, two fillers

Many newer diesels around Ferndale, as well as Tylorstown, run on two fluids; the motor takes only your diesel. Stored in a tank of its own, AdBlue is fed into the exhaust gas to clean it.

Every tank has one filler of its own. Some motors put the AdBlue filler in your boot or under the bonnet; plenty more have the two together behind one flap. Topping up your diesel side at the petrol pump happens all the time. Far less commonly, the AdBlue side gets topped up — mostly from a bottle, by someone working out where it goes. The error lives in that gap.

AdBlue in the diesel tank in Tylorstown: how it occurs

Carelessness rarely explains it. What does is three things coming up at once.

First, the warning. Low AdBlue brings a warning from your car, and running out leads to limp mode — so a hurried top-up, maybe before work off Hirwain Place, perhaps outside the pub in the village on the way home after work.

Next, your hand reaches for the cap it would have used on the old motor — because a hire car, a new car or a company car puts the fillers somewhere your last one did not.

A spout-topped bottle meets no obstacle at a diesel filler any more than at an AdBlue one. So the tip, once begun, keeps on. Whether it happens in Stanleytown or the middle of Tylorstown, it is the same few seconds.

How to tell the AdBlue filler from the diesel one

Check these before pouring, at a forecourt around Tylorstown or a drive out in Llanwonno. Seconds, no more.

  • The cap. The AdBlue cap is regularly blue, or marked "AdBlue". Your diesel cap usually is not. Read it rather than going by position.
  • The size. On many motors the AdBlue filler neck is the smaller of the two.
  • A label inside your fuel flap often says which fuel goes where, on plenty of cars. Check for it.
  • In your boot or under the bonnet: that's where the filler is if it's not by the diesel cap, and the handbook says which.
  • The person who drove the vehicle last. On a hire or company car collected from somewhere like the car park outside Llwynypia, ask before you leave, not when the light comes on.

AdBlue top-ups that never reach the diesel tank

A routine for the day the light comes on, wherever in Rhondda Cynon Taf that is.

  • Park then switch off. Not on a slope, not with the engine running, and not in a rush on the side of Pendyrus Court.
  • Find the AdBlue filler, check the cap, and speak the word "AdBlue" aloud as unscrewing it. It sounds daft. It works.
  • The two under one flap? Then confirm the cap on the diesel filler stays shut ahead of raising the bottle.
  • Finish once that tank fills or the bottle runs dry; before that, pour gently using the built-in spout.
  • Shut the cap, and look again — making sure the diesel filler stayed shut throughout. Only then, start your car.

Find at the second or third stage that the bottle went in the diesel tank? That is where you stop. Leave out step five altogether.

Put AdBlue in the diesel tank around Tylorstown already?

Then the order of things is short. Do not start your motor. On plenty of diesels your ignition alone runs the fuel pump, so do not switch the vehicle on. Diluting it with more diesel won't work, since AdBlue settles to the bottom rather than mixing — and that's where the fuel is pulled from.

On a forecourt — Shell, Murco or any other — the attendants will usually help push your car away, if you ask. Leave it where it is if you are on your own drive in Tylorstown.

Stop as soon as it is safe and switch off, if the motor has already run. The next junction means the place to leave if you are on the M4, under 10 miles from Tylorstown. Mileage counts — a short hop across Tylorstown makes a smaller job than heading under 25 miles towards Cardiff — so say about how far it went.

Our arrival around Tylorstown, and what happens next

We come to the vehicle wherever it has stopped, whether that is outside the local primary school, near Tylorstown Welfare Hall or on your own drive. Both the work and the quote depend on three replies — what fluid, what quantity, and whether it's run — so we ask. No one heads out before you have had the price over the phone.

Emptying the tank comes next, then a full flush of the system. With AdBlue that counts more than with petrol: it crystallises and is corrosive to some of the metals in a fuel system, so it doesn't wash out on its own. After the fuel filter has been flushed — or renewed, where required — clean diesel is added, and then the car gets tested. Before we leave, we start it and check that it's running smoothly.

Unrun vehicles mostly mean a half-hour visit from the moment we arrive. The equipment is fine on a live forecourt, and quiet enough for a residential street late at night. Nothing in advance; you settle up that day. At the end, the VAT invoice and a report from the engineer go to you for the insurer. Misfuelling cover is included in many insurance policies — so make use of the wait to check yours.
