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

Diesel goes to the motor — yet plenty of modern diesels driven round Salford Quays and Trafford Park carry a second fluid too. AdBlue goes to your exhaust, where it is sprayed into the gas to clean it, and it lives in a tank of its own.

There is a filler on every tank. Some motors put the AdBlue filler in your boot or under the bonnet; a lot more have the two together behind one flap. The diesel side is fuelled at the petrol pump all the time. Rarely topped up, AdBlue normally comes from a bottle, poured by someone who has to stop and think which filler to use. The mistake grows in the gap between the two.

Salford Quays: how AdBlue in the diesel tank takes place

It's hardly ever carelessness. Three things tend to line up.

To start with, the warning. Low AdBlue triggers a message from the car, and letting it run out leads to limp mode — hence a hurried top-up, maybe before work off Broadway, perhaps outside Seven Bro7hers Media City on the way home that evening.

Next, the hand goes for the cap it knew on the old motor — since a rental car, a new motor or a company car puts the fillers somewhere your last one did not.

A spout-topped bottle finds no obstacle at a diesel filler no more than at an AdBlue one. So the pour, once started, carries on. Whether it occurs in Weaste or the middle of Salford Quays, it is the same few seconds.

The AdBlue filler and your diesel filler: telling them apart

Before you tip anything, whether on a driveway in Seedley or a forecourt in Salford Quays, check these. They take a couple of seconds.

  • Read the cap rather than going by position: AdBlue ones are commonly blue or marked "AdBlue", and diesel caps usually are not.
  • Look at the size: the smaller filler neck is, on many vehicles, the AdBlue one.
  • Check inside the fuel flap: many cars carry a label there showing which fuel goes where.
  • The handbook says which it is if your filler is not next to the diesel cap: the boot, or under the bonnet.
  • Collecting a hire or company car, perhaps at the car park at Manchester United Football Club? Check with whoever drove the car last before leaving, rather than once the light goes on.

AdBlue top-ups that never reach the diesel tank

A routine for the day the light comes on, wherever in Greater Manchester that is.

  • Stop on level, motor off, with time in hand — not hurried on the side of Blue.
  • Find the AdBlue filler and read the cap. Say "AdBlue" out loud as you unscrew it. It sounds silly and it does the trick.
  • Both under a single flap? Then make sure the cap on the diesel side is still shut ahead of lifting the bottle.
  • Stop once that tank is topped up or the bottle runs dry; until then, tip gently using its own spout.
  • Close the cap and check once more. Make sure your diesel cap was never opened. Only then start the car.

Find during the second or third step that the bottle went in the wrong filler? That is where you stop. Skip stage five altogether.

Salford Quays: already put AdBlue in the diesel tank?

Then the order of things is short. Do not start the motor. The fuel pump starts on many diesels as soon as your ignition goes on — and so keep it off. Do not top up with diesel to thin it: AdBlue does not mix with diesel, it sinks to the bottom of your tank, where the fuel is pulled from.

The staff at BP, Esso or another forecourt will usually help to push the vehicle clear if you ask. Your own drive in Salford Quays is the place it should stay.

Stop as soon as it is safe and switch off, if your motor has already run. Leave the M602 — under a mile out of Salford Quays — at the next exit. Mileage matters — a short hop across Salford Quays makes a smaller job than driving under a mile to Salford — so tell us about how far it went.

Salford Quays: what happens when our technicians arrive

Outside Willow Tree Primary School, near Upsy Daisy or on your own drive: wherever the vehicle has stopped, our technicians come to it. We ask what got in, roughly how much, and whether it has run, because those replies determine the work and the price. During the call itself, you hear our quote — ahead of dispatch.

The system is then flushed thoroughly, after the tank is emptied. Unlike petrol, AdBlue forms crystals and eats at some fuel-system metals, and none of it washes out unaided. That is why it matters more. Your filter is cleaned, or replaced where it needs to be; clean diesel goes in; and your car is tested. The motor is started next and tested to be sure it runs correctly, all before our technicians go.

Unstarted cars usually mean a half-hour job after the moment we arrive. The equipment is safe on a busy filling station, and quiet enough for a residential street after dark. Payment is on the day, not upfront, and you receive the documents an insurer wants: an engineer's report and a VAT invoice. Wrong-fuel cover is included in plenty of insurance policies — so make use of the wait to check yours.
