Why does AdBlue in a diesel vehicle need its own filler?

Many current diesels on the roads around Lower Tadmarton and Swalcliffe carry two liquids, not one. Diesel goes to your engine. Kept in a tank of its own, AdBlue is fed into the exhaust gas to clean it.

Each tank has its own filler. Many of motors have a single flap for both, whereas some move the AdBlue filler to your boot or under the bonnet. Diesel gets filled at every filling station visit, week in, week out. Far less commonly, the AdBlue side gets filled — mostly from a bottle, by a person thinking about where it goes. The slip lives in that gap.

How does AdBlue in your diesel tank occur around Lower Tadmarton?

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

On a driveway off Hollow Road before work, or in the car park at Lampet Arms heading home: that is where the rushed top-up happens. What is the reason for the rush? As AdBlue runs low your car tells you, and once it's empty, limp mode kicks in.

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

Lastly, the bottle goes in: a diesel filler or AdBlue one, it slides in as easily, and once the pour starts, nothing halts it. The same few seconds settle it, in the middle of Lower Tadmarton or out in High Meadow View.

Flushing a diesel fuel system after AdBlue, Lower Tadmarton

Which filler is for AdBlue, and which for diesel?

A couple of seconds is all the checks take — so check them before you pour anything, on a driveway in Milcombe or a forecourt in Lower Tadmarton.

  • Position misleads; the cap doesn't. AdBlue caps tend to be blue or bear the word "AdBlue" — diesel caps normally don't.
  • Many motors give AdBlue the smaller filler of the two.
  • The flap. Look inside the fuel flap for a label. Plenty of cars say there which fuel goes where.
  • The handbook shows where it is if your filler is not next to your diesel cap: the boot, or under the bonnet.
  • Ask the person who drove it last — before you leave, not when the light comes on — when you pick up a hire or company car from somewhere like the car park at Banbury.

How to top up without AdBlue in the diesel tank

For the day the light comes on — wherever it is across Oxfordshire — a routine to use.

  • Stop somewhere level, motor off, with time in hand — not rushing on the side of B4035.
  • Find the AdBlue filler and read the cap. Say "AdBlue" out loud as you unscrew it. It sounds silly and it does the trick.
  • The diesel cap remains on. Where the two sit under a flap, confirm it is closed before the bottle comes up.
  • Stop when that tank is topped up or the bottle is empty; before that, pour gently using its built-in spout.
  • Shut the cap, then look again — confirm the diesel cap stayed closed throughout. After that, start the car.

Find during the second or third stage that AdBlue went into the wrong filler? That is where you stop. Do not go on to step five.

Put AdBlue in your diesel tank around Lower Tadmarton already?

Brief list, then. Top of it: your motor stays unstarted. Leave the ignition off too, because on many diesels it by itself runs the pump. Diluting it with extra diesel fails, since AdBlue sinks to the bottom rather than mixing — and that is where the fuel is drawn from.

If you're at a forecourt, whether it's the BP or the Sainsbury's, ask the attendants to help roll the vehicle clear of the petrol pump. If you're on your own driveway around Lower Tadmarton, leave it where it is.

Already started? Pull over once it's sensible, then turn off. Lower Tadmarton sits under 5 miles from the M40; there, take the next exit. A short hop across Lower Tadmarton is a smaller job than a run towards Oxford, under 25 miles away, so tell us roughly how far it went.

When our technicians turn up in Lower Tadmarton, what takes place?

Anywhere the car came to rest, be it by Bloxham Church of England Primary School, beside Saint Nicholas or at home, our van comes to it. Both the work and our quote depend on three answers — which fluid, which quantity, and if it has run — so our technicians ask. You hear that quote by phone, before anyone heads out.

Next: a drain, then a thorough flush of the whole system. Not like petrol, AdBlue forms crystals and attacks certain fuel-system metals, and neither washes out by itself. That is why it matters more. After the fuel filter has been cleaned — or renewed, where needed — fresh diesel goes in, and then the car is tested. Your engine is started next and tested to be sure it runs properly, all before our engineers leave.

Unrun vehicles mostly need a half-hour visit from arrival. The kit is fine on a busy forecourt, and hushed enough for a driveway late at night. No money in advance; you settle up that day. Afterwards, a VAT invoice and a report from the engineer go to you for your insurer. It's worth checking your insurance while we travel to you: misfuelling cover comes with plenty of policies.
