Ossaborough: How Does AdBlue End Up in a Diesel Tank, and How Do You Prevent It?

AdBlue already in the diesel tank? In that case put this page aside for now, leave the ignition and motor off, then phone 0333 366 0103. In Ossaborough, finding it before the motor runs normally means draining and a full flush where it stands. If you're reading before it has happened, the remainder of this page is about why it occurs and how to make sure it does not.

AdBlue in a diesel motor: two tanks, two fillers

Not one fluid but two: that's how plenty of modern diesels near Ossaborough and Dean carry, with diesel feeding your engine. The exhaust, not the engine, is where AdBlue goes: dosed into the gas to clean them, from its own tank.

Separate tanks, different fillers. On a lot of vehicles the two sit side by side under the same flap; on others the AdBlue filler is in the boot or under the bonnet. Filling your diesel side at the pump happens constantly. The AdBlue side is filled far less frequently, normally from a bottle, and normally by somebody who has to stop and think where it goes. That gap is where the slip lives.

How does AdBlue in the diesel tank take place around Ossaborough?

Seldom is it carelessness: normally three things coincide.

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

Unfamiliar vehicles are next, as well. Hire cars, new vehicles and company cars put their fillers in new places, and habit goes for the cap used on the old one.

A spouted bottle finds no resistance at a diesel filler no more than at an AdBlue one. And so the pour, after started, carries on. Whether it takes place in Willingcott or the middle of Ossaborough, it's the same few seconds.

How to tell the AdBlue filler from the diesel one

Check these before pouring, at a forecourt in Ossaborough or a drive out in Dean Cross. A few seconds, that's all.

  • The cap. The AdBlue cap is often blue, or marked "AdBlue". The diesel cap normally isn't. Read it rather than going by position.
  • Look at the size: the smaller neck is, on many cars, the AdBlue one.
  • Open the flap and look for a label — many vehicles show what goes in each inlet right there.
  • The handbook. If your filler is not by the diesel cap, it is in the boot or under the bonnet, and the handbook says which.
  • The person who drove it last. On a hire or company car picked up from somewhere like the car park at Barnstaple, ask before you leave, not when the light comes on.

Keeping AdBlue out of your diesel tank when you top up

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

  • Stop somewhere level, engine off, with time in hand — not hurried on the side of Trimstone Lane.
  • Find the AdBlue filler and read the cap. Say "AdBlue" out loud as you unscrew it. It sounds daft and it works.
  • Both behind a single flap? Then confirm the lid on the diesel filler stays closed ahead of lifting the bottle.
  • Pour slowly, using the bottle's own spout. Stop when it's full or when the bottle is empty.
  • Before you start the vehicle, shut the cap and look a second time that the diesel cap was never came off.

Find at the second or third step that AdBlue went in the wrong tank? That is where you stop. Step five stays off limits.

Ossaborough: already put AdBlue in your diesel tank?

What follows is a short order of things, beginning with no starting your engine. Keep your ignition off too, since on many diesels switching it on alone runs your 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 the fuel is drawn from.

The staff at Golden Coast Service Station, Murco or any forecourt will usually lend a hand to push the vehicle clear if asked. If you are on your own driveway in Ossaborough, leave the vehicle where it stands.

If the motor has already run, stop as soon as it is safe and switch off. On the M4, under 50 miles from Ossaborough, that means the next exit. Mileage matters — a short hop across Ossaborough makes a smaller job than heading under 50 miles towards Swansea — so tell us roughly how far it went.

Our arrival in Ossaborough, and what occurs next

Our van reaches the car anywhere it has come to rest — your own driveway, near Segway Safari, or by Woolacombe School. The replies determine this work and the price, so our technicians ask what got in, about how much, and whether it's run. That quote is given over the phone, before any van leaves.

Next: draining, 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, and so it doesn't wash out on its own. A test is last: before that, fresh diesel goes in, and the filter is cleaned or replaced as needed. Before leaving, our engineers start the car and check that it's running correctly.

If your motor has not run, the majority of jobs take about half an hour once we're there, using pumps that are safe on a working forecourt and quiet enough to use outside a house after dark. The insurer will ask for the engineer's report and your VAT invoice, and both are yours at the end. Payment comes on the day, with no money upfront. Many insurance policies include misfuelling cover, so it is worth checking yours while we're on the way.
