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

Diesel goes to your engine — yet many current diesels driven around Hurlet and Priesthill hold another liquid too. 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's a filler for every tank. Some cars put the AdBlue filler in your boot or under the bonnet; plenty of others place both side by side under one flap. At the petrol pump, your diesel side is topped up all the time. Someone who has to stop and think where it goes normally tops up the AdBlue side, from a bottle, and far less frequently. The mistake grows in that gap between them.

AdBlue in the diesel tank in Hurlet: how it happens

Three things tend to come together, and carelessness is rarely one of them.

To start with, the warning. Low AdBlue brings a message from your car, and running out leads to limp mode — hence a hurried top-up, perhaps before work off Glasgow Road, or outside the pub in the village on the way home that evening.

Then the car is unfamiliar. A hire car, a new vehicle or a company car puts the fillers where your last one didn't, and your hand reaches 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, and so nothing stops the tip once it has started. Whether it takes place in Nitshill or the middle of Hurlet, it's the same few seconds.

The AdBlue filler and the diesel filler: telling them apart

A few seconds is all these take — so run through them before you tip anything, on a drive in Bowerwalls or a forecourt around Hurlet.

  • Check the cap rather than going by where it sits: AdBlue caps are often blue or marked "AdBlue", and diesel caps normally aren't.
  • On many motors, size gives it away: AdBlue has the smaller filler neck.
  • The flap. Look inside the fuel flap for a label. Plenty of motors say there which fuel goes where.
  • The handbook says where it lives when the filler is not next to your diesel cap: your boot, or under the bonnet.
  • Check with 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 Nitshill.

Topping up AdBlue without it reaching the diesel tank

For the day the warning comes on — wherever you are around East Renfrewshire — a routine to use.

  • Turn off once parked — level ground, engine stopped, and not in a rush by Hurlet Road on the verge.
  • Silly as it sounds, saying "AdBlue" out loud as you unscrew the cap does the trick — after you've found the filler and read it.
  • If both sit under one flap, check the diesel cap is still closed before you lift the bottle — and leave the vehicle on.
  • Slowly does it, through the bottle's own spout, until it's full or the bottle runs out.
  • Before starting the car, close the cap and look a second time that the diesel cap never opened off.

Discover at the second or third stage that the bottle went in the wrong tank? That's where you stop. Stage five stays off limits.

Already put AdBlue in the diesel tank in Hurlet?

What follows is a short order of things, starting with not starting your engine. Leave your ignition off as well, since on plenty of diesels it by itself runs the fuel pump. Don't top up with diesel to thin it: AdBlue doesn't mix with diesel, it sinks to the bottom of that tank, where the fuel is sucked from.

On a forecourt — Barrhead Services, Esso or another — the attendants will normally help push the car clear, if you ask. On your own drive in Hurlet? Then the car remains put.

Where your engine has been run by now, pull over safely and switch it off. The next exit means where to come off when you're on the M77, under 3 miles from Hurlet. Tell us about how far it went: a run towards Glasgow, under 10 miles away, is a bigger job than a short hop across Hurlet.

What happens when our engineers get there around Hurlet

Wherever the vehicle has stopped, whether outside the local primary school, beside Glasgow Museums Resource Centre or at home, our van comes to it. What fluid was put in, the quantity, and if it ran: our technicians ask because the replies decide both work and quote. That price comes on the call, before any van leaves.

After that: a drain, then a full flush of the whole 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. Testing comes last: before that, fresh diesel goes in, and the fuel filter is cleaned or replaced as needed. After that our engineers fire it up and confirm it runs correctly before leaving.

Most jobs are finished in about half an hour once our engineers arrive, provided the engine has not run — and the pumps our engineers use are safe on a busy forecourt yet quiet after dark beside a house. The insurer usually wants the engineer's report and the VAT invoice, and you get both at the end. Payment comes on the day, with no deposit. It's worth looking at your insurance while we travel to you: misfuelling cover is included with plenty of policies.
