AdBlue in a diesel motor: two tanks, two fillers

Many newer diesels on the roads around Nether Moor and Netherthorpe carry two liquids, not one. Diesel goes to the engine. AdBlue's own tank holds it, and from there it is sent to the exhaust, and there a spray cleans the gas.

Each tank has its own filler. Many of vehicles have a single flap for both, whereas some put the AdBlue filler to your boot or under the bonnet. Diesel gets filled at every forecourt visit, again and again. Seldom filled, AdBlue usually comes out of a bottle, tipped by a driver who has to stop and think what cap it needs. The mistake lives in that gap.

How does AdBlue in the diesel tank occur around Nether Moor?

Seldom is it carelessness: usually three things line up.

The warning comes first. As AdBlue runs low your car tells you, and if it runs out altogether, your vehicle goes into limp mode. So the top-up is done in a hurry: on a driveway off Nethermoor Close before work, or in the car park at The Crown Inn on the way home.

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

Nothing halts the tip after it has started, since a bottle with a spout goes into a diesel filler as readily as an AdBlue one. The bottle fits. Nether Green or the heart of Nether Moor: it is the same few seconds either way.

Which filler is for AdBlue, and which for diesel?

Look at these before pouring, on a forecourt around Nether Moor or a driveway out in Norwood. A few seconds, that's all.

  • Colour and marking: an AdBlue cap is frequently blue, or says "AdBlue", where a diesel cap normally doesn't. Go by the cap, not its position.
  • On plenty of cars, size gives it away: AdBlue has the smaller filler neck.
  • A label inside your fuel flap often says which fuel goes where, on plenty of vehicles. Check for it.
  • Can't see it beside the diesel filler? Then check below the bonnet or in your boot — the handbook will say where.
  • Whoever had it before knows. Ask as you collect a rental or company car — at Kiveton Bridge's car park, perhaps — not when the light appears.

Topping up AdBlue without it reaching your diesel tank

When the light goes on, anywhere around Derbyshire, use this routine.

  • Not in a rush on the side of Nethermoor Drive, not on a slope, not with the engine running: park and switch off first.
  • Locate the AdBlue filler, read the cap, and speak the name "AdBlue" aloud while you unscrew it. It sounds daft. It works.
  • The diesel cap remains on. Where the two share a flap, make sure it's shut before lifting the bottle.
  • Slowly does it, through the bottle's own spout, till it's full or the bottle is empty.
  • Only after that, start your car: close the cap, check once more, and make sure your diesel cap was never opened.

Stop there if you find, at step two or three, that you've already poured into your diesel side. Don't carry on to stage five.

Put AdBlue in your diesel tank in Nether Moor already?

Then the order of things is short. Do not start the motor. Leave your ignition off as well, because on many diesels it by itself starts the fuel pump. Do not top up with diesel to dilute it: AdBlue doesn't mix with diesel, it sinks to the bottom of the tank, where your fuel is sucked from.

The attendants at the nearest petrol station, BP or any forecourt will usually lend a hand pushing your car clear if asked. Leave it where it is if you're on your own driveway in Nether Moor.

Already started? Pull over once it's sensible, then switch off. Nether Moor lies under 3 miles from the M1; there, use the next exit. Mileage matters — a short hop across Nether Moor is a smaller job than driving under 10 miles towards Sheffield — so tell us about how far it went.

What happens when our engineers get there in Nether Moor

The van reaches your car anywhere it has come to rest — your own driveway, beside Killamarsh Library, or by Killamarsh Infant School. Which liquid got in, the quantity, and whether it ran: we ask because the replies decide both work and price. Nobody heads out before you've heard our quote over the phone.

Your system is then rinsed thoroughly, after your tank is cleared. AdBlue crystallises and is corrosive to some of the metals in a fuel system, and so it does not wash out on its own — which is why that matters more here than with petrol. Testing comes at the end: before that, fresh diesel is added, and the fuel filter is cleaned or replaced as needed. Your engine is started next and tested to make sure it runs correctly, all before we go.

Unstarted vehicles mostly mean a half-hour visit from the moment we arrive. The equipment is fine on a live forecourt, and hushed enough for a driveway late at night. The insurer usually wants the engineer's report and your VAT invoice, and you get both once this job is done. Payment is on the day, with no deposit. Misfuelling cover is included in many insurance policies — so make use of the wait to check yours.
