AdBlue in a diesel motor: two tanks, two fillers

Many modern diesels in Ryhill, as well as South Hiendley, run on two liquids; the motor takes just your diesel. Its own tank keeps it, and from there it is sent to your exhaust, where a spray cleans the gas.

Each tank comes with one filler of its own. Some vehicles put the AdBlue filler in the boot or under the bonnet; a lot of others have both together under one flap. The diesel side is filled at the pump all the time. Someone who has to stop and work out where it goes normally tops up the AdBlue side, from a bottle, and much less often. That gap is where the mistake lives.

How AdBlue in the diesel tank happens in South Hiendley

Three things tend to come together, and carelessness is seldom one of them.

The warning comes first. As AdBlue runs low the car tells you, and if it runs out completely, the car drops into limp mode. So the top-up is done in a hurry: on a driveway off Main Street before work, or in the car park at Sun Inn on the way home.

Unfamiliar vehicles come second, as well. Hire cars, new motors and company motors put their fillers differently, and the hand reaches for the cap it used on the old one.

Third, the spout fits: diesel filler or AdBlue one, it slides in just as readily, and once the tip starts, no part stops it. Felkirk or the heart of South Hiendley: it takes the same few seconds in both.

How to tell the AdBlue filler from the diesel one

Be it a South Hiendley forecourt or a driveway out in Newstead, spend a few seconds on these before any goes in.

  • Check the cap instead of going by where it sits: AdBlue ones are often blue or marked "AdBlue", and diesel caps usually are not.
  • Look at the size: the smaller neck is, on plenty of cars, the AdBlue one.
  • A label inside the fuel flap often says which fuel goes where, on many cars. Check for it.
  • Cannot see it next to your diesel inlet? In that case check below the bonnet or in the boot — the owner's manual will say where.
  • Collecting a hire or company car, perhaps at the car park outside Fitzwilliam? Check with whoever drove it last before leaving, rather than once the light comes on.

Topping up AdBlue without it reaching the diesel tank

When the light goes on, wherever around West Yorkshire, follow this routine.

  • Pull in on level, motor off, with time to spare — never rushing on the side of George Street.
  • Say "AdBlue" out loud as you unscrew the cap, once you find the AdBlue filler and reading it. Daft, perhaps, yet it works.
  • The two under one flap? Then make sure the lid on your diesel side is still shut before raising the bottle.
  • Finish when your tank is topped up or the bottle is empty; before that, pour slowly using the own spout.
  • Close the cap, then check again — confirm your diesel cap remained shut throughout. Only then, start the vehicle.

If at stage two or three you find you have already poured into your diesel side, stop there. Step five stays out.

South Hiendley: already put AdBlue in the diesel tank?

Brief order, then. Top of that: the engine remains off. Do not switch the ignition on; on plenty of diesels that alone runs the fuel pump. Thinning it with extra diesel fails, since AdBlue sinks to the base rather than mixing — and that is where the fuel is sucked from.

Ask the staff to help roll the vehicle clear of the petrol pump if you are on a forecourt — the Tesco, the JET or anywhere else. At home in South Hiendley? So your car remains put.

Stop as soon as it is safe and switch off, if your engine has already run. The next junction means where to leave when you're on the M1, under 10 miles from South Hiendley. Tell us about how far it went: a run towards Wakefield, under 10 miles away, is a bigger job than a short hop across South Hiendley.

South Hiendley: what takes place when our engineers turn up

The van reaches the vehicle anywhere it stopped — your own drive, near St Peter, Felkirk, or outside South Hiendley Primary School. Which liquid went in, the quantity, and whether it ran: our technicians ask because those answers decide the work and price. No one sets off until you have had the price over the phone.

Next: draining, then a full flush of the entire system. Much more than with petrol, it counts here: the crystals build up, certain metals are attacked, and nothing washes away on its own, no matter how long it is left. After the filter has been flushed — or replaced, where required — fresh diesel goes in, and finally your car is tested. Before leaving, we fire it up and check that it is running smoothly.

With pumps safe on a working forecourt and quiet enough to use outside a house at night, most jobs in which the motor hasn't run need about half an hour once we arrive. You pay on the day, with nothing upfront, and get a VAT invoice and an engineer report for your insurer. It's worth checking your policy as the van travels to you: misfuelling cover comes with plenty of policies.

Awkward to explain, like the back of St Paul's Methodist Church? Close to a county line? Checking is better than assuming, so phone.
