Why It Occurs and How to Avoid It: AdBlue in a Diesel Tank in Noke Street

Pause reading a minute when the diesel tank already holds AdBlue in it: ignition off, motor off, and call 0333 366 0103. In Noke Street, finding it before the engine turns normally leaves draining and a full flush on the spot. Reading before the event? In that case the rest covers how it happens and how to stop it happening at all.

AdBlue in a diesel vehicle, and its separate tank

Diesel feeds your engine — but many modern diesels seen round Noke Street and Frindsbury carry a second fluid as well. AdBlue goes to your exhaust, where it is sprayed into the gas to clean it, and it lives in a tank of its own.

Each tank has its own filler. Plenty of vehicles share a single flap for the two, while others put the AdBlue filler to your boot or under the bonnet. At the pump, your diesel side gets filled all the time. The AdBlue side is filled far less often, normally from a bottle, and normally by someone who has to stop and think where it goes. That gap is where the error lives.

Noke Street: how AdBlue in your diesel tank happens

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

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

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

A spouted bottle finds no obstacle at a diesel filler any more than at an AdBlue one. So the pour, once begun, carries on. It's seconds, whether out in Wainscott or bang in the centre of Noke Street.

Telling the AdBlue filler from the diesel filler

Check these first, on a forecourt around Noke Street or a drive over in Cliffe Woods. A few seconds, no more.

  • Position misleads; the cap does not. AdBlue ones tend to be blue or bear the word "AdBlue" — diesel caps normally do not.
  • Many cars fit AdBlue the smaller filler of the two.
  • The flap. Look inside your fuel flap for a label. Plenty of cars say there which fuel goes where.
  • Cannot see it next to your diesel filler? Then look beneath the bonnet or inside your boot — the owner's manual will say where.
  • Picking up a hire or company car, say at the car park outside Strood? Ask whoever drove it last before you set off, rather than when the light comes on.

AdBlue top-ups that never reach the diesel tank

On the day the light appears — wherever it is around Kent — a routine to use.

  • Not in a rush on the side of Hasted Road, not on a slope, not with your motor running: park and switch off first.
  • Find the AdBlue filler, check the cap, and say the name "AdBlue" aloud as unscrewing it. It sounds daft. It does the trick.
  • Both behind a single flap? So confirm the cap on your diesel side is still shut ahead of raising the bottle.
  • Finish when that tank fills or the bottle runs dry; until then, pour slowly through the own spout.
  • Before you start the car, close the cap and look a second time that your diesel cap never opened off.

If at step two or three you find you have already poured into the diesel side, stop there. Never carry on to step five.

Noke Street: already put AdBlue in the diesel tank?

What follows is a short order of things, beginning with not starting the engine. The fuel pump runs on many diesels as soon as your ignition is switched on — so leave it off. AdBlue doesn't mix with diesel — it sinks to the bottom of that tank, where the fuel is sucked from — so do not top up with diesel to dilute it.

At a forecourt — Esso, JET or any other — the staff will normally help push the car clear, if you ask. Leave it where it is if you're on your own drive around Noke Street.

Already started? Pull over when it is sensible, then switch off. On the M2, under 3 miles from Noke Street, that means the next junction. Tell us roughly how far it went: a run towards Southend-on-Sea, under 15 miles away, is a bigger job than a short hop across Noke Street.

When we arrive around Noke Street, what takes place?

Our technicians come to your car wherever it has stopped, whether that is outside Wainscott Primary School, close to Memorial Hall or on your own drive. The replies determine the work and our quote, and so we ask what went in, about how much, and if it's run. You hear that price by phone, before anybody sets off.

The fuel system is then flushed thoroughly, after your tank is emptied. Not like petrol, AdBlue leaves crystals and attacks certain fuel-system metals, and none of it washes out by itself. That is why it matters more. Testing is last: before that, fresh diesel is added, and your filter is flushed or replaced as needed. The motor is fired up next and checked to make sure it runs smoothly, all before our engineers head off.

Unrun vehicles mostly need a half-hour job after arrival. The kit is fine on a busy filling station, and quiet enough for a driveway after dark. Paying is on the day, not upfront, and you receive the paperwork your insurer asks for: an engineer report and a VAT invoice. It is worth looking at your policy while we travel to you: misfuelling cover is included with many policies.

The car does not need to shift. Anywhere it sits — beside Frindsbury Tennis Club, in a lay-by heading to Wainscott Park, on a drive — that is where it gets drained. Tricky to explain, like the back of Frindsbury Cricket Club? Close to a county line? Asking beats guessing, so ring.
