Two fillers, two tanks: AdBlue in a diesel vehicle

Plenty of modern diesels on the roads around Farnborough Park and Mytchett carry two liquids, not one. Diesel goes to the engine. Your exhaust, not your engine, is where AdBlue goes: dosed into the gas to fresh them, from a separate tank.

There's a filler on every tank. On a lot of cars the two sit side by side under the same flap; on others the AdBlue filler is in your boot or under the bonnet. The diesel side is filled at the petrol pump all the time. Rarely topped up, AdBlue usually comes from a bottle, tipped by someone who must stop and think what filler to use. The slip lives in that gap.

How AdBlue in the diesel tank occurs around Farnborough Park

Three things tend to line up, and carelessness is rarely one of them.

On a drive off Rectory Road before work, or in the car park at The Tilly Shilling heading home: that's where the rushed top-up happens. What is the reason for the rush? As AdBlue gets low the vehicle warns you, and if it's empty, limp mode kicks in.

Then, the hand reaches for the cap it knew on the old vehicle — because a hire car, a new car or a company car puts the fillers somewhere your last one didn't.

A spouted bottle meets no obstacle at a diesel filler no more than at an AdBlue one. And so the tip, after started, keeps on. Whether it happens in Farnborough Street or the middle of Farnborough Park, it is the same few seconds.

How to tell the AdBlue filler from the diesel one

A few seconds is all the checks take — so run through them before you tip anything, on a driveway in Frimley Green or a forecourt around Farnborough Park.

  • Read the cap instead of going by where it sits: AdBlue ones are regularly blue or marked "AdBlue", and diesel caps normally are not.
  • Check the size: the smaller neck is, on many cars, the AdBlue one.
  • The flap. Look inside the 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 is if it's not by your diesel cap, and the handbook tells you which.
  • Picking up a hire or company car, say at the car park at Farnborough Main? Ask the person who drove the car last before leaving, not once the light comes on.

AdBlue top-ups that never reach your diesel tank

The day the light comes on, wherever around Hampshire, use this routine.

  • Pull in somewhere level, motor off, with time to spare — not hurried on the side of Avenue Road.
  • Locate the AdBlue filler, read the cap, and say the name "AdBlue" out loud as you unscrew 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 it on.
  • Stop once the tank fills or the bottle is empty; before that, pour slowly through the built-in spout.
  • Close the cap and check a second time. Make sure your diesel cap was never opened. Only then start the car.

Stop there if you find, at stage two or three, that you have already poured into your diesel side. Stage five stays out.

Put AdBlue in the diesel tank around Farnborough Park already?

Then the order of things is short. Do not start your engine. Do not switch the ignition on; on plenty of diesels that alone runs the fuel pump. Do not top up with diesel to dilute it: AdBlue does not mix with diesel, it sinks to the bottom of the tank, where your fuel is pulled from.

Ask the staff to help push the car away from the petrol pump if you are at a forecourt — the JET, the BP or anywhere else. Leave it where it is if you are on your own drive around Farnborough Park.

When your motor has run by now, stop safely then turn the vehicle off. The next exit is where to leave when you are on the M3, under 3 miles from Farnborough Park. Roughly how far did it go? Crossing Farnborough Park is smaller work than a run of under 50 miles to Winchester, so say.

Our arrival around Farnborough Park, and what takes place next

Anywhere the car came to rest, be it by St Patrick's Catholic Primary School, near St. Peter's or on your own drive, our van travels to it. Those answers determine the work and the quote, so our technicians ask what was put in, about how much, and if it has run. The quote is given over the phone, before any van leaves.

After that: draining, then a thorough flush of the whole 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. Once your filter has been flushed — or renewed, where required — clean diesel goes in, and finally the car is tested. We don't go until it has been started and is running correctly.

Unrun vehicles usually mean a half-hour visit after arrival. The kit is safe on a live forecourt, and hushed enough for a driveway after dark. Nothing upfront; you settle up on the day. At the end, a VAT invoice and a report from the engineer are handed to you for your insurer. Many insurance policies include misfuelling cover, so it's worth checking yours whilst we are on the way.

Farnborough and South Farnborough are among the places around Farnborough Park, a residential suburb, that the same vans cover, throughout GU postcodes. Quickest of all: give a GU14 7 postcode to our van.

Moving the vehicle isn't necessary. The drain takes place on the spot, whether a driveway, a street by 8th Farnborough Scout Group, or a lay-by on the way to St. Peter's playing fields. Awkward to pin down, like the back of St. Michael's Abbey Church? By a border? Checking is better than guessing, and so ring.
