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

Pause here a minute when the diesel tank already holds AdBlue in it: ignition off, motor off, then call 0333 366 0103. A drain and a thorough flush, done right where your car sits around Kinross, is normally what it takes when found before the engine runs. Here in advance? In that case the rest covers why it happens and how to prevent it ever happening.

AdBlue in a diesel car: two tanks, two fillers

Diesel feeds your engine — yet many modern diesels seen around Kinross and East Coldrain hold a second fluid too. Its own tank holds it, and from there it is sent to your exhaust, and there spraying treats the fumes.

Separate tanks, separate fillers. Many of motors share a single flap for the two, while others move the AdBlue filler to the boot or under the bonnet. Diesel goes in on every forecourt visit, week in, week out. Far less often, the AdBlue side gets topped up — normally from a bottle, by someone thinking about where it goes. It is in the gap that the slip happens.

Kinross: how AdBlue in the diesel tank happens

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

Haste follows from the warning. The vehicle tells you as AdBlue runs low, and an empty tank sends the vehicle into limp mode — so the top-up happens in a rush, before work on a driveway off High Street, or heading home in the car park at Kirklands.

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

Third, the spout goes in: diesel filler or AdBlue one, it slides in just as easily, and after the tip starts, no part halts it. Whether it occurs in Milnathort or the middle of Kinross, it's the same few seconds.

Flushing a diesel fuel system after AdBlue, Kinross

Which filler is for AdBlue, and which for diesel?

A couple of seconds is all the checks take — so run through them before you tip anything, on a driveway in West Netherton or a forecourt in Kinross.

  • Read the cap instead of going by where it sits: AdBlue ones are frequently blue or marked "AdBlue", and diesel ones usually are not.
  • The size. On many cars the AdBlue filler neck is the smaller of the two.
  • Open the filler flap and look for a label — plenty of vehicles mark which belongs in which filler right there.
  • In your boot or under the bonnet: that's where the filler is if it is not by your diesel cap, and the handbook says which.
  • Picking up a hire or company car, say at the car park outside Lochgelly? Ask whoever drove it last before leaving, not once the light comes on.

Topping up AdBlue without it reaching the diesel tank

On the day the light appears — anywhere you are around Perth and Kinross — a routine to follow.

  • Park and switch off. Not on a slope, not with your engine running, and not in a rush on the side of Talla Park.
  • Find the AdBlue filler, check the cap, and speak the name "AdBlue" out loud as unscrewing it. It seems silly. It works.
  • If both sit under one flap, check your diesel cap is still closed before you lift the bottle — then leave the car on.
  • Tip slowly, using the bottle's own spout. Stop when it is full or when the bottle is empty.
  • Before starting the car, shut the cap and look a second time that the diesel cap never came off.

Find at step two or three that it has already gone into the diesel side? So stop right there. Step five stays out.

Put AdBlue in the diesel tank around Kinross already?

The short order of things, starting with not starting the engine. Keep your ignition off too, because on many diesels it by itself runs the pump. Filling up with diesel will not dilute it: instead, AdBlue sinks to the base of that tank, just where the fuel is drawn from.

Ask the attendants to help roll the car clear of the pump if you're at a forecourt — the BP, the Thames or somewhere else. If you are on your own driveway in Kinross, leave the vehicle where it stands.

Already run? Stop once it's safe, then switch off. The next exit is the place to leave when you are on the M90, under a mile from Kinross. Tell us about how far it went: a run towards Dunfermline, under 10 miles away, is a bigger job than a short hop across Kinross.

When we arrive around Kinross, what takes place?

Our van comes to the car anywhere it stopped — your own driveway, beside Kinross Church, or outside the local primary school. Both the work and our quote depend on three answers — which liquid, what amount, and if it's run — so our engineers ask. The quote is given on the call, ahead of any van leaving.

Draining your tank comes next, followed by a thorough flush of your system. Unlike petrol, AdBlue leaves crystals and attacks some fuel-system metals, and neither clears out by itself. Hence it matters more. A test comes at the end: before that, clean diesel is added, and your filter is flushed or replaced as needed. The engine is fired up next and checked to make sure it runs properly, all before we leave.

Using pumps safe on a working forecourt and quiet enough to use outside a house at night, most jobs where the motor hasn't run take about half an hour after our technicians are there. Your insurer usually wants an engineer's report and the VAT invoice, and both are yours once the job is done. Payment is on the day, with no money upfront. It is worth checking your insurance while we travel to you: misfuelling cover comes with many policies.
