AdBlue in a diesel car, and its separate tank

Many newer diesels in Garth, as well as Maesgeirchen, run on two fluids; the motor takes just your diesel. Kept in a tank of its own, AdBlue is fed into your exhaust stream to clean it.

Each tank comes with a filler of its own. Under one flap, next to each other: that is the arrangement on a lot of motors. On others, AdBlue's filler is under the bonnet or in the boot instead. Topping up the diesel side at the petrol pump goes on all the time. A driver who has to stop and work out where it goes normally fills the AdBlue side, from a bottle, and much less often. That gap is where the slip lives.

AdBlue in your diesel tank around Maesgeirchen: how it occurs

Carelessness seldom causes it. Instead is three things lining up together.

The warning comes first. As AdBlue runs low the car tells you, and if it runs out completely, the vehicle goes into limp mode. So the top-up is done in a hurry: on a drive off Rhodfa Penrhyn / Penrhyn Avenue before work, or in the car park outside The Skerries on the way home.

Unfamiliar cars are next, too. Rentals, new motors and company motors put their fillers in new places, and habit goes for the cap used on the old one.

A spouted bottle meets no obstacle at a diesel filler no more than at an AdBlue one. So the pour, once begun, keeps on. Hirael or the middle of Maesgeirchen: it is the same few seconds in both.

How to tell the AdBlue filler from the diesel one

Be it a Maesgeirchen forecourt or a drive out in Upper Bangor, take a few seconds on these before any is poured in.

  • Position can mislead; the cap does not. AdBlue ones tend to be blue or carry the word "AdBlue" — diesel ones normally don't.
  • Many cars fit AdBlue the smaller filler of the two.
  • Check inside the fuel flap: plenty of cars have a label there saying which fuel goes where.
  • Cannot see it beside the diesel inlet? Then check beneath the bonnet or in the boot — the handbook says which.
  • Picking up a hire or company car, perhaps at the car park at Bangor (Gwynedd)? Check with whoever drove it last before leaving, not when the light comes on.

Keeping AdBlue out of your diesel tank when you top up

Wherever across Gwynedd the light comes on, here is a routine for the day.

  • Pull in somewhere level, motor off, with time to spare — not rushing on the side of Rhodfa Kingsley.
  • Find the AdBlue filler, check the cap, and say the word "AdBlue" out loud while you unscrew it. It sounds daft. It works.
  • Leave your diesel cap on. If both sit under one flap, check your diesel cap is still closed before you lift the bottle.
  • Slowly is best, through the bottle's own spout, until it's full or the bottle is empty.
  • Close the cap and check once more. Make sure the diesel cap was never opened. Only then start your car.

Find at stage two or three that it's already gone into your diesel side? So stop just there. Never go on to stage five.

Already put AdBlue in the diesel tank in Maesgeirchen?

What follows is a short order of things, beginning with not starting the engine. Leave your ignition off as well, since on many diesels it by itself starts the pump. Topping up with diesel will not weaken it: instead, AdBlue sinks to the base of your tank, right where the fuel is taken from.

Ask the staff to help push your car away from the pump if you are at a forecourt — the BP, the Asda or anywhere else. At home around Maesgeirchen? Then your car stays where it is.

If your motor has already run, stop as soon as it is safe then switch off. The next exit means the place to leave if you're on the Moreton Spur, under 50 miles from Maesgeirchen. Tell us about how far it went: a run towards Bangor, under a mile away, is a bigger job than a short hop across Maesgeirchen.

Maesgeirchen: what occurs when we arrive

The van comes to the car wherever it has come to rest — your own drive, beside Eglwys y Groes, or by the local primary school. What fluid went in, the amount, and whether it ran: our engineers ask because those answers decide both work and price. No one sets off before you've had the price by phone.

Your system is then cleaned thoroughly, after the tank is drained. Not like petrol, AdBlue leaves crystals and attacks some fuel-system metals, and none of that clears out unaided. Hence it counts more. The fuel filter is cleaned, or replaced where it needs to be; clean diesel goes in; and the car is tested. After that we fire it up and confirm it runs properly before leaving.

If the motor hasn't run, most jobs take about half an hour once we are there, using pumps that are safe on a working forecourt and quiet enough to use outside a house after dark. No money in advance; you settle up that day. Afterwards, the VAT invoice and the report from the engineer are handed to you for the insurer. Misfuelling cover is included in many insurance policies — and so make use of the wait to look at yours.
