AdBlue in a diesel motor: two tanks, two fillers

Plenty of modern diesels around Stainton, like those in Willow Holme, run on two liquids; the engine takes just your diesel. AdBlue goes to the exhaust, where it is sprayed into the gas to clean it, and it lives in a tank of its own.

Different tanks, separate fillers. Plenty of motors have a single flap for the two, whereas others put the AdBlue filler to your boot or under the bonnet. Diesel gets filled on each filling station call-out, week in, week out. A driver who has to stop and think where it goes usually tops up the AdBlue side, from a bottle, and much less regularly. It's in that gap that the mistake lives.

How AdBlue in the diesel tank happens in Willow Holme

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

To start with, the warning. Low AdBlue brings a message from the vehicle, and running dry means limp mode — so a hurried top-up, perhaps before work off Millrace Road, or outside Jovial Sailor on the way home that evening.

Then the vehicle is new. A hire car, a new motor or a company car puts the fillers where your last one did not, and your hand reaches for the cap it would have used on the old one.

A spout-topped bottle finds no obstacle at a diesel filler no more than at an AdBlue one. So the pour, after begun, keeps on. Whether it occurs in Newtown or the middle of Willow Holme, it is the same few seconds.

Flushing a diesel fuel system after AdBlue, Willow Holme

Which filler is for AdBlue, and which for diesel?

Be it a Willow Holme forecourt or a drive over in Morton, spend a few seconds on these before anything is poured in.

  • Check the cap instead of going by position: AdBlue caps are frequently blue or marked "AdBlue", and diesel caps usually are not.
  • The size. On many motors the AdBlue filler neck is the smaller of the two.
  • Look inside your fuel flap: plenty of cars carry a label there saying which fuel goes where.
  • Cannot see it next to the diesel filler? In that case look beneath the bonnet or inside the boot — the owner's manual will say where.
  • The person who drove the car last. On a hire or company car picked up from somewhere like the car park at Carlisle, ask before you leave, not when the light comes on.

AdBlue top-ups that never reach the diesel tank

The day the light comes on, wherever across Cumbria, use this routine.

  • Switch off once parked — flat ground, engine off, and not rushed by Canal Court at the roadside.
  • Find the AdBlue filler, read the cap, and speak the word "AdBlue" aloud as you unscrew it. It sounds daft. It does the trick.
  • Leave the diesel cap on. If both sit under one flap, check your diesel cap is still closed before you lift the bottle.
  • Stop when the tank is topped up or the bottle is empty; until then, tip slowly through its own spout.
  • Close the cap, and look again — making sure your diesel filler remained shut the whole time. After that, start the vehicle.

Stop there if you find, at step two or three, that you have already poured into the diesel side. Stage five stays off limits.

Already put AdBlue in your diesel tank in Willow Holme?

Brief list, then. First: your engine remains off. Keep your ignition off too, since on plenty of diesels it by itself starts your fuel pump. Filling up with diesel will not thin it: instead, AdBlue sinks to the base of that tank, just where fuel is drawn from.

If you're on a forecourt, whether it's the Sainsbury's or the Asda, ask the attendants to help roll the vehicle clear of the petrol pump. At home around Willow Holme? So the vehicle remains where it is.

Stop as soon as it is safe then switch off, if the engine has already run. On the M6, under 3 miles from Willow Holme, that means the next junction. About how far did it go? Crossing Willow Holme is less work than a run of under a mile towards Carlisle, so tell us.

What happens when our engineers get there around Willow Holme

Anywhere the car came to rest, be it by Caldew Lea School, beside Fusion Trampoline Park or at home, our van travels to it. Those answers decide the work and our price, so our technicians ask what was put in, about how much, and if it has run. You get that price by phone, before anyone heads out.

Then the tank is drained and the system flushed thoroughly. Much more than with petrol, it matters with AdBlue: the crystals form, certain metals corrode, and nothing clears away unaided, no matter how long it sits. Testing comes at the end: before that, fresh diesel is added, and your filter is flushed or changed as needed. The motor is started next and checked to be sure it runs correctly, all before we head off.

If the motor has not run, most jobs take about half an hour once we are there, using pumps that are safe on a busy forecourt and quiet enough to use outside a house at night. Nothing upfront; you settle up on the day. At the end, a VAT invoice and the report from the engineer go to you for the insurer. Before we get there, take a look at your policy; plenty include cover for misfuelling.
