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

If AdBlue is already in your diesel tank, stop reading for a moment: leave your engine and the ignition off and call 0333 366 0103. Around Sheepbridge, catching it before your engine turns usually means a drain 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 doesn't.

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

Plenty of newer diesels on the roads around Sheepbridge and Old Whittington carry two liquids, not one. Diesel goes to your engine. The exhaust, not the motor, is where AdBlue goes: sprayed into the gas to clean it, from a separate tank.

Different tanks, separate fillers. Other cars put the AdBlue filler in your boot or under the bonnet; a lot more have both side by side under one flap. At the petrol pump, your diesel side is topped up constantly. Someone who has to stop and work out where it goes normally tops up the AdBlue side, from a bottle, and much less frequently. It is in that gap that the error lives.

Sheepbridge: how AdBlue in the diesel tank occurs

It is rarely carelessness. Three things tend to line up.

First, the warning. Low AdBlue triggers a message from your car, and running out means limp mode — so a hurried top-up, perhaps before work off Foxwood Road, perhaps at Bulls Head on the way home after work.

Then the vehicle is new. A hire car, a new motor or a company car puts the fillers where your last one didn't, and your hand gets to for the cap it would have used on the old one.

Nothing halts the tip after it has started, since a bottle with a spout goes into a diesel filler as easily as an AdBlue one. The bottle fits. The same few seconds settle it, in the middle of Sheepbridge or out in The Brushes.

Telling the AdBlue filler from your diesel filler

Be it a Sheepbridge forecourt or a drive out in Whittington Moor, take a few seconds on these before any goes in.

  • Check the cap instead of going by where it sits: AdBlue caps are frequently blue or marked "AdBlue", and diesel ones normally aren't.
  • On many motors, the size tells: AdBlue has the smaller filler neck.
  • The flap. Look inside the fuel flap for a label. Many cars say there which fuel goes where.
  • Cannot see it beside the diesel filler? Then check beneath the bonnet or inside your boot — the owner's manual will say where.
  • Picking up a hire or company car, perhaps at the car park outside Chesterfield? Check with whoever drove the vehicle last before leaving, not once the light comes on.

Topping up AdBlue without it reaching your diesel tank

When the light comes on, anywhere across Derbyshire, use this routine.

  • Not in a rush on the side of Sheepbridge Lane, not on a slope, not with your motor running: park and switch off properly.
  • Say "AdBlue" out loud as you unscrew the cap, once finding the AdBlue filler and read it. Daft, perhaps, yet it works.
  • Both under a single flap? So confirm the cap on your diesel side is still closed ahead of lifting the bottle.
  • Stop once your tank is topped up or the bottle runs dry; until then, tip slowly through its built-in spout.
  • Close the cap and check a second time. Make sure the diesel cap was never opened. Only then start your car.

Stop there if you find, at step two or three, that you have already poured into your diesel side. Never go on to stage five.

AdBlue in the diesel tank already, around Sheepbridge?

Do not start the motor: that's how the short order of things starts. Don't switch your ignition on; on many diesels that alone runs the fuel pump. Don't top up with diesel to dilute it: AdBlue does not mix with diesel, it sinks to the bottom of your tank, where the fuel is pulled from.

If you're at a forecourt, whether it is the Esso or the Tesco, ask the attendants to help roll the vehicle away from the petrol pump. Leave it where it is if you are on your own driveway in Sheepbridge.

If your motor has already run, stop as soon as it is safe and switch off. Sheepbridge sits under 5 miles from the M1; there, take the next exit. Tell us about how far it went: a run towards Sheffield, under 10 miles away, is a bigger job than a short hop across Sheepbridge.

Our arrival around Sheepbridge, and what happens next

Our technicians come to the car wherever it has stopped, whether that's outside Cavendish Junior School, close to Revolution House or on your own driveway. The replies decide this work and the price, and so we ask what was put in, roughly how much, and if it's run. On the call itself, you are told the quote — before dispatch.

After that: a drain, then a full flush of the whole system. Unlike petrol, AdBlue leaves crystals and attacks some fuel-system metals, and none of that washes out by itself. That is why it matters more. The filter cleaned or, where it must be, replaced; clean diesel in; then a check of your car. After that we start it and check it runs correctly before leaving.

If your engine has not run, most 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. You pay on the day, with nothing upfront, and get a VAT invoice and an engineer report for your insurer. Plenty of insurance policies include misfuelling cover, and so it is worth checking yours whilst we're on the way.
