Two fillers, two tanks: AdBlue in a diesel car

Diesel feeds the engine — but many current diesels seen round Western Park and Braunstone Frith carry another fluid too. Your exhaust, not your motor, is where AdBlue goes: sprayed into the gas to clean it, from a separate tank.

Each tank has its own filler. On a lot of motors the two sit side by side under the same flap; on others the AdBlue filler is in your boot or under the bonnet. Filling the diesel side at the petrol pump goes on all the time. Rarely filled, AdBlue normally comes from a bottle, poured by a driver who has to stop and think which cap to use. The slip lives in that gap.

How AdBlue in the diesel tank takes place in Western Park

Seldom is it carelessness: usually three things coincide.

The warning comes first. As AdBlue runs low the car tells you, and if it runs out altogether, your vehicle goes into limp mode. So the top-up is done in a hurry: on a drive off Letchworth Road before work, or in the car park outside The Good Neighbours on the way home.

The old car's filler is where the hand reaches — yet a hire car, a new motor or a company car puts the fillers somewhere else. That's the second factor: a new vehicle.

And the bottle fits. A bottle with a spout goes into a diesel filler as easily as an AdBlue one, so nothing stops the pour after it has started. It's seconds, be it out in New Parks or right in the centre of Western Park.

Telling the AdBlue filler from your diesel filler

Check these first, on a forecourt in Western Park or a drive over in Frog Island. A few seconds, no more.

  • Check the cap instead of going by position: AdBlue ones are regularly blue or marked "AdBlue", and diesel caps normally are not.
  • On many motors, size gives it away: AdBlue has the smaller filler neck.
  • The flap. Look inside your fuel flap for a label. Plenty of vehicles say there which fuel goes where.
  • In the boot or under the bonnet: that's where the filler sits if it is not by your diesel cap, and the handbook tells you which.
  • Check with the person who drove it last — before you leave, not when the light comes on — when you collect a hire or company car from somewhere like the car park at Leicester.

AdBlue top-ups that never reach your diesel tank

The day the light goes on, wherever in Leicestershire, follow this routine.

  • Not in a rush on the side of Hilders Road, not on a slope, not with your motor running: park and switch off properly.
  • Daft as it sounds, saying "AdBlue" aloud while you unscrew the cap works — after you have found your filler and read the cap.
  • The diesel cap stays on. When the two share a flap, make sure it's closed before lifting the bottle.
  • Tip slowly, using the bottle's own spout. Stop when it is full or when the bottle is empty.
  • Shut the cap, then check once more — making sure the diesel filler remained shut throughout. Only then, start the car.

Find at the second or third stage that AdBlue went in the diesel tank? That is where you stop. Skip stage five entirely.

Already put AdBlue in the diesel tank around Western Park?

Brief order, then. First: your engine remains off. The fuel pump starts on plenty of diesels as soon as your ignition is switched on — and so keep it off. Don't top up with diesel to dilute it: AdBlue does not mix with diesel, it sinks to the bottom of that tank, where your fuel is drawn from.

On a forecourt — Esso, Texaco or any other — the staff will usually help push the vehicle away, when you ask. If you are on your own drive around Western Park, leave the car where it stands.

Stop as soon as it is safe and switch off, if your motor has already run. The next exit is where to leave if you are on the M1, under 3 miles from Western Park. A short hop across Western Park is a smaller job than a run towards Leicester, under 3 miles away, so tell us about how far it went.

Western Park: what occurs when our technicians arrive

The van comes to your car wherever it has come to rest — your own drive, beside St Anne's Parish Church, or by Christ the King Catholic Voluntary Academy. Both the work and our price depend on three replies — what fluid, which amount, and if it's run — so our technicians ask. You hear that price by phone, before anyone heads out.

Draining that tank comes next, followed by a thorough flush of your system. With AdBlue that counts more than with petrol: it crystallises and is corrosive to some of the metals in a fuel system, so it does not wash out on its own. After the filter is cleaned — or renewed, where needed — fresh diesel is added, and then the vehicle is tested. Your engine is fired up next and checked to make sure it runs properly, all before our engineers go.

If the engine hasn't run, the majority of jobs take about half an hour once we're there, using pumps that are fine on a working forecourt and quiet enough to use outside a house after dark. The insurer will ask for an engineer's report and your VAT invoice, and both are yours at the end. Payment comes on the day, with no deposit. It's worth looking at your insurance as the van travels to you: misfuelling cover comes with plenty of policies.
