Why does AdBlue in a diesel vehicle need its own filler?

Plenty of modern diesels around Old Thirsk, as well as New Thirsk, carry on two liquids; your motor takes just your diesel. AdBlue goes to your exhaust, where it is sprayed into the gas to fresh it, and it lives in a tank of its own.

Each tank has 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 gets filled at every filling station visit, again and again. Much less commonly, the AdBlue side gets topped up — normally from a bottle, by someone thinking about where it goes. Mistakes happen in the gap between them.

How does AdBlue in your diesel tank happen around New Thirsk?

Carelessness rarely causes it. What does is three things coming up together.

First, the warning. Low AdBlue triggers a warning from your car, and letting it run dry means limp mode — so a rushed top-up, perhaps before work off Masonic Lane, perhaps at Cross Keys on the way home that evening.

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

And the bottle fits. A bottle with a spout goes into a diesel filler as easily as an AdBlue one, so nothing stops the tip after it has started. Whether it happens in Norby or the middle of New Thirsk, it is the same few seconds.

How to tell the AdBlue filler from the diesel one

Check these before pouring, at a forecourt around New Thirsk or a driveway over in Miry Hole. A few seconds, that's all.

  • Read the cap rather than going by where it sits: AdBlue caps are regularly blue or marked "AdBlue", and diesel caps usually are not.
  • Many motors give AdBlue the smaller neck of the two.
  • A label inside the fuel flap often says which fuel goes where, on plenty of vehicles. Check for it.
  • The handbook. If your filler is not by your diesel cap, it's in the boot or under the bonnet, and the handbook says which.
  • The previous driver will know. Check when you pick up a hire car or company car — from Thirsk's car park, say — rather than when the light appears.

Topping up AdBlue without it reaching your diesel tank

On the day the light comes on — wherever it is in North Yorkshire — a simple routine to follow.

  • Pull in on level, motor off, with time to spare — not hurried on the side of Newsham Road.
  • Say "AdBlue" out loud as you unscrew the cap, once you find the AdBlue filler and reading it. Silly, perhaps, but it does the trick.
  • If both sit under one flap, check the diesel cap is still closed before you lift the bottle — and leave the car on.
  • Tip slowly, using the bottle's own spout. Stop when it is full or when the bottle is empty.
  • Before you start the car, shut the cap and look again that your diesel cap never opened off.

If at step two or three you find you have already poured into the diesel side, stop there. Never carry on to step five.

Already put AdBlue in your diesel tank in New Thirsk?

What follows is a short order of things, starting with no starting your engine. On many diesels the ignition alone runs the fuel pump, and so do not switch the vehicle on. AdBlue does not mix with diesel — it sinks to the bottom of your tank, where your fuel is pulled from — so don't top up with diesel to thin it.

Ask the staff to help push the car clear of the pump if you're on a forecourt — the Tesco, the Esso or somewhere else. Leave it where it is if you are on your own driveway around New Thirsk.

Stop as soon as it is safe and switch off, if the motor has already run. New Thirsk sits under 10 miles from the A1(M); on it, use the first exit. A short hop across New Thirsk is a smaller job than a run towards Ripon, under 10 miles away, so tell us about how far it went.

When our technicians turn up around New Thirsk, what occurs?

By All Saints Catholic Primary School, a Catholic Voluntary Academy, close to Bamlett's or on your own drive: wherever the vehicle has stopped, our engineers come to it. Both the work and our quote rest on three answers — which fluid, which amount, and if it's run — so our engineers ask. You hear that price by phone, before anyone heads out.

Draining that tank comes next, then a thorough flush of the system. More than with petrol, it matters with AdBlue: the crystals form, certain metals are attacked, and none of that clears out on its own, however long it sits. Your filter is cleaned, or replaced where it needs to be; clean diesel goes in; and the car is tested. The motor is fired up next and tested to confirm it runs properly, all before our technicians head off.

Most jobs are finished in roughly half an hour once we arrive, provided your engine hasn't run — and the pumps our technicians use are fine on a live forecourt yet quiet at night beside a house. You pay on the day, with nothing upfront, and get a VAT invoice and an engineer report for your insurer. Wrong-fuel cover is included in many insurance policies — and so make use of the wait to look at yours.
