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

No single liquid but two: that's how many newer diesels near Milford and Cowhill carry, with diesel for the motor. Stored in a tank of its own, AdBlue is sprayed into the exhaust gas to clean it.

Each tank has its own filler. On a lot of motors the two sit side by side under the same flap; on others the AdBlue filler is in the boot or under the bonnet. Diesel gets filled at each filling station visit, week in, week out. A driver who has to stop and think where it goes usually tops up the AdBlue side, from a bottle, and much less frequently. It is in the gap that the mistake happens.

AdBlue in the diesel tank around Milford: how it takes place

Three things tend to line up, and carelessness is rarely one of them.

On a drive off Makeney Road before work, or in the car park at King William on the way home: that's where the rushed top-up takes place. What is the reason for the rush? As AdBlue runs low the vehicle tells you, and if it's gone, limp mode follows.

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

Third, the spout fits: a diesel filler or AdBlue filler, it goes in just as easily, and once the tip begins, nothing stops it. The same few seconds settle it, in the middle of Milford or out in Makeney.

How to tell the AdBlue filler from the diesel one

A few seconds is all the checks take — so run through them before you tip anything, on a drive in Bargate or a forecourt in Milford.

  • Where it sits misleads; the cap doesn't. AdBlue ones are often blue or bear the name "AdBlue" — diesel ones usually do not.
  • Plenty of vehicles give AdBlue the smaller neck of the two.
  • A label inside the fuel flap frequently shows which fuel goes where, on many cars. Look for it.
  • Cannot find it next to your diesel inlet? Then check below the bonnet or in the boot — the handbook will say where.
  • Picking up a hire or company car, perhaps at the car park at Duffield? Ask the person who drove the car last before leaving, not when the light comes on.

AdBlue top-ups that never reach your diesel tank

A routine for the day the light comes on, wherever across Derbyshire that is.

  • Pull in on level, engine off, with time to spare — never hurried on the side of Derby Road.
  • Find the AdBlue filler and read the cap. Say "AdBlue" out loud as you unscrew it. It sounds silly and it does the trick.
  • The diesel cap stays on. Where the two sit under a flap, make sure it's closed before the bottle comes up.
  • Using the bottle's own spout, pour slowly — and stop when it is full or the bottle is empty.
  • Before starting your car, close the cap and look a second time that your diesel cap was never opened off.

Stop there if you find, at step two or three, that you've already poured into the diesel side. Skip stage five entirely.

Already put AdBlue in your diesel tank around Milford?

Don't start your motor: that's how the short order of things starts. On plenty of diesels your ignition alone runs the fuel pump, so do not switch it on. AdBlue doesn't mix with diesel — it sinks to the bottom of the tank, where the fuel is pulled from — so don't top up with diesel to dilute it.

The staff at Morrisons, JET or another forecourt will normally lend a hand to push the vehicle away if you ask. Your own driveway around Milford is the place it stays.

Stop as soon as it is safe and switch off, if your engine has already run. Leave the M1 — under 10 miles out of Milford — at the first exit. Distance counts — a short hop across Milford is a smaller job than driving under 10 miles towards Derby — so tell us roughly how far it went.

Our arrival in Milford, and what happens next

By Milford Primary School, near Riverside Fitness Centre or on your own driveway: wherever the vehicle has stopped, we come to it. Our engineers ask what was put in, roughly how much, and whether it's run, because the answers determine the work and the price. On the call itself, you are told the quote — ahead of dispatch.

Emptying that tank comes next, then a thorough flush of your system. With AdBlue that matters 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. The filter is cleaned, or replaced where it needs to be; fresh diesel goes in; and the car is tested. Before we leave, we fire it up and check that it's running smoothly.

Using pumps safe on a working forecourt and quiet enough for use outside a house at night, most jobs where the engine has not run need about half an hour after we arrive. Paying is on the day, not upfront, and you receive the documents your insurer wants: an engineer's report and a VAT invoice. Many insurance policies include misfuelling cover, so it's worth checking yours whilst we're on the way.

Milford and Derbyshire: AdBlue drains across the area

As a village, Milford has the same vans as nearby areas — Holbrook, Holbrook Moor — right through DE postcodes and the wider area around them. Our van reaches you fastest with a postcode starting DE56 0.

The vehicle remains where it is. Wherever it sits — beside Kawagishi Dojo, on a layby en route to Squirrel Woods, on a drive — that's where it gets emptied. Ring and ask rather than assuming if you are close to a boundary, or somewhere hard to describe, like the back of Duffield Castle.

In short, for Milford drivers

Before you tip, read the cap. Petrol in Diesel drains it where it stands, anywhere across Derbyshire, if AdBlue has gone in your diesel tank regardless — so leave the vehicle off then phone 0333 366 0103.
