AdBlue in a diesel vehicle: two tanks, two fillers

Many modern diesels around Burton Lazars, as well as Melton Mowbray, run on two liquids; the motor gets just the diesel. Kept in a tank of its own, AdBlue is sprayed into the exhaust stream to clean it.

There's a filler on each tank. Many of vehicles have a single flap for the two, whereas others move the AdBlue filler to your boot or under the bonnet. At the petrol pump, the diesel side gets filled all the time. The AdBlue side is topped up far less regularly, usually from a bottle, and normally by someone who has to stop and think where it goes. It is in the gap that the slip lives.

How AdBlue in your diesel tank happens around Melton Mowbray

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

Haste follows from the warning. The car warns you as AdBlue runs low, and a dry tank sends it into limp mode — so the top-up gets done quickly, before work on a drive off Nottingham Street, or on the way home in the car park outside The White Lion.

Unfamiliar cars come second, too. Rentals, new motors and company cars put their fillers in new places, and habit goes for the cap it used on the old one.

A spout-topped bottle meets no resistance at a diesel filler no more than at an AdBlue one. So the tip, after begun, keeps on. It's a few seconds, be it in Thorpe Arnold or right in the heart of Melton Mowbray.

How to tell the AdBlue filler from the diesel one

A couple of seconds is all the checks take — so run through them before you tip anything, on a driveway in Potter Hill or a forecourt around Melton Mowbray.

  • Read the cap instead of going by where it sits: AdBlue ones are frequently blue or marked "AdBlue", and diesel ones normally are not.
  • Look at the size: the smaller filler neck is, on plenty of vehicles, the AdBlue one.
  • A label inside the fuel flap frequently shows which fuel goes where, on plenty of cars. Check for it.
  • The handbook shows which it lives when your filler isn't next to the diesel cap: your boot, or under the bonnet.
  • The person who drove the car last. On a hire or company car picked up from somewhere like the car park at the nearest station, ask before you leave, not when the light comes on.

How to top up without AdBlue in your diesel tank

A routine for the day the light comes on, wherever across Leicestershire that is.

  • Turn off once parked — level ground, motor stopped, and not in a rush by Park Road at the roadside.
  • Find the AdBlue filler and read the cap. Say "AdBlue" out loud as you unscrew it. It sounds daft and it does the trick.
  • Leave the diesel cap on. If both sit under one flap, check the diesel cap is still closed before you lift the bottle.
  • Slowly is best, through the bottle's own spout, until it's full or the bottle runs out.
  • Before starting the car, shut the cap and check again that the diesel cap never came off.

Discover at the second or third step that the bottle went into the diesel tank? That's where you stop. Never go on to step five.

Already put AdBlue in the diesel tank around Melton Mowbray?

What follows is a short order of things, starting with not starting your motor. On plenty of diesels the ignition alone runs the fuel pump, so do not switch it on. Thinning it with extra diesel fails, since AdBlue settles to the bottom rather than blending — and that is where the fuel is sucked from.

If you are on a forecourt, whether it is the BP or the Esso, ask the attendants to help roll your car clear of the pump. If you are on your own drive in Melton Mowbray, leave the vehicle where it stands.

When your motor has run by now, pull over safely then switch the car off. The next exit means the place to come off if you are on the M1, under 25 miles from Melton Mowbray. About how far did it go? Crossing Melton Mowbray is smaller work than a run of under 15 miles towards Leicester, and so say.

When our technicians turn up in Melton Mowbray, what occurs?

Wherever the vehicle has stopped, whether outside The Grove Primary School, near Melton Mowbray Library and Adult Learning Centre or on your own drive, our van comes to it. What fluid got in, the quantity, and whether it ran: our engineers ask because the replies decide the work and quote. That price comes on the call, ahead of any van leaving.

Next: a drain, then a full flush of the whole system. AdBlue crystallises and is corrosive to some of the metals in a fuel system, so it does not wash out on its own — which is why that matters more with AdBlue than with petrol. Testing is at the end: before that, fresh diesel goes in, and the filter is flushed or changed if necessary. Then our technicians start the engine and check it runs smoothly before we go.

If the engine has not run, most jobs take about half an hour once we're there, using pumps that are fine on a busy 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. It's worth looking at your policy as the van travels to you: misfuelling cover is included with many policies.
