AdBlue in a diesel motor: two tanks, two fillers

Many modern diesels on the roads around Bleak Hills and Newton Town carry two liquids, not one. Diesel goes to your engine. Your exhaust, not your engine, is where AdBlue goes: dosed into the fumes to fresh them, from a separate tank.

Each tank has its own filler. Other cars put the AdBlue filler in your boot or under the bonnet; a lot more have the two together under one flap. Topping up the diesel side at the pump happens constantly. The AdBlue side is filled far less frequently, normally from a bottle, and usually by a person who has to stop and think where it goes. The mistake lives in that gap.

Bleak Hills: how AdBlue in the diesel tank occurs

Rarely is it carelessness: usually three things coincide.

On a drive off Maunside before work, or in the car park outside Nell Gwyn heading home: that is where the hurried top-up happens. What is the reason for the rush? As AdBlue runs low your car tells you, and once it's gone, limp mode kicks in.

Then, the hand reaches for the cap it would have used on the old car — because a rental car, a new vehicle or a company car places the fillers where your last one did not.

A spout-topped bottle meets no obstacle at a diesel filler no more than at an AdBlue one. And so the pour, after begun, carries on. Whether it occurs in Ladybrook or the middle of Bleak Hills, it is the same few seconds.

The AdBlue filler and the diesel filler: telling them apart

Before you tip anything, whether on a driveway in Dalestorth or a forecourt in Bleak Hills, check these. They take a few seconds.

  • Where it sits can mislead; the cap does not. AdBlue caps are often blue or bear the word "AdBlue" — diesel ones usually do not.
  • The size. On many motors the AdBlue filler neck is the smaller of the two.
  • Lift the flap and check for a label — plenty of cars mark which goes in each inlet just there.
  • In your boot or under the bonnet: that's where the filler is if it is not by the diesel cap, and the handbook tells you which.
  • Picking up a hire or company car, perhaps at the car park outside Mansfield? Check with the person who drove the vehicle last before leaving, rather than once the light goes on.

How to top up without AdBlue in your diesel tank

A routine for the day the light comes on, wherever around Nottinghamshire that is.

  • Park then switch off. Not on a slope, not with the engine running, and not in a rush on the side of Hermitage Lane.
  • 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 shut before the bottle comes up.
  • Pour slowly, using the bottle's own spout. Stop when it's full or when the bottle is empty.
  • Shut the cap, then check again — confirm the diesel cap remained shut throughout. Only then, start the car.

Stop there if you find, at step two or three, that you have already poured into your diesel side. Do not go on to stage five.

AdBlue in the diesel tank already, in Bleak Hills?

The short order of things, beginning with no starting your motor. The fuel pump runs on many diesels as soon as the ignition is switched on — so keep it off. Filling up with diesel won't dilute it: instead, AdBlue drops to the base of that tank, right where the fuel is drawn from.

At a forecourt — Morrisons, Sainsbury's or another — the attendants will normally help roll the vehicle clear, if you ask. Leave it where it is if you're on your own drive around Bleak Hills.

Already started? Stop once it's safe, then switch off. The next exit means where to leave if you're on the M1, under 5 miles from Bleak Hills. A short hop across Bleak Hills is a smaller job than a run towards Nottingham, under 15 miles away, and so tell us about how far it went.

What takes place when our engineers arrive around Bleak Hills

Anywhere your car has stopped, be it outside Sutton Road Primary School, near Hermitage Mill or on your own drive, the van travels to it. Both the work and our price rest on three answers — which fluid, what quantity, and if it has run — so we ask. During the phone call itself, you are told the price — ahead of anything else.

Emptying that tank comes next, followed by a thorough flush of the system. With AdBlue that matters more than with petrol: it crystallises and is corrosive to some of the metals in a fuel system, and so it doesn't wash out on its own. The fuel filter is flushed, or replaced where it needs to be; clean diesel goes in; and your car is tested. Before we go, our technicians fire it up and check that it's running properly.

If your motor has not run, the majority of jobs take about half an hour once we're there, using pumps that are fine on a busy forecourt and quiet enough to use outside a house at night. You pay on the day, with nothing upfront, and get a VAT invoice and an engineer report for your insurer. It is worth looking at your insurance while we travel to you: misfuelling cover is included with many policies.

AdBlue drains across Nottinghamshire, Bleak Hills included

Mansfield and Sutton Forest Side are among the places around Bleak Hills, a residential suburb, that the same vans cover, over NG postcodes. Fastest of all: quote a NG18 5 postcode to the van.

Moving the vehicle is not necessary. A driveway, a lay-by on the way to The Oakham Local Nature Reserve (North), a side street near Odeon: we drain the vehicle where it is. If you're close to a boundary, or somewhere hard to describe like the back of Salvation Army Church, ring and ask instead of assuming.
