AdBlue in a diesel motor: two tanks, two fillers

Many modern diesels on the roads around Townsend and Northwood carry two liquids, not one. Diesel goes to the engine. Its own tank keeps it, and from there it is sent to your exhaust, where a spray treats the fumes.

Each tank has its own filler. Plenty of vehicles have a single flap for both, whereas some put the AdBlue filler to the boot or under the bonnet. Topping up your diesel side at the petrol pump happens constantly. Rarely topped up, AdBlue normally comes out of a bottle, tipped by someone who has to stop and think which cap to use. It is in the gap that the error happens.

AdBlue in your diesel tank around Townsend: how it happens

Carelessness seldom causes it. What does is three things coming up at once.

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

Then your car is strange. A hire car, a new vehicle or a company car puts the fillers where your last one did not, and the hand reaches for the cap it would have used on the old one.

And the bottle fits. A bottle with a spout goes into a diesel filler as easily as an AdBlue one, so nothing stops the tip once it has started. Bucknall or the heart of Townsend: it takes the same few seconds either way.

Flushing a diesel fuel system after AdBlue, Townsend

The AdBlue filler and the diesel filler: telling them apart

Before you tip anything, whether on a drive in Birches Head or a forecourt around Townsend, check these. They take a couple of seconds.

  • The cap. The AdBlue cap is often blue, or marked "AdBlue". The diesel cap usually is not. Read it rather than going by position.
  • On many cars, the size gives it away: AdBlue has the smaller filler neck.
  • Look inside your fuel flap: plenty of motors carry a label there showing which fuel goes where.
  • Cannot find it beside your diesel filler? Then look beneath the bonnet or in the boot — the owner's manual will say where.
  • The person who drove the car last. On a hire or company car picked up from somewhere like the car park outside Stoke-On-Trent, ask before you leave, not when the light comes on.

AdBlue top-ups that never reach your diesel tank

Wherever around Staffordshire the light comes on, this is a routine for the day.

  • Turn off after you park — flat ground, motor stopped, and not rushed beside Corneville Road on the verge.
  • Find the AdBlue filler, read the cap, and say the name "AdBlue" aloud while you unscrew it. It sounds daft. It works.
  • If both sit under one flap, check the diesel cap is still closed before you lift the bottle — then leave the car on.
  • Finish once your tank is topped up or the bottle is empty; until then, tip gently using its built-in spout.
  • Before you start your car, close the cap and check again that the diesel cap was never opened off.

Discover during the second or third stage that the bottle went into the diesel tank? That's where you stop. Skip step five altogether.

Townsend: already put AdBlue in the diesel tank?

Don't start the engine: that's where the short order of things begins. On plenty of diesels the ignition alone runs the fuel pump, and so don't switch the vehicle on. AdBlue does not mix with diesel — it sinks to the bottom of the tank, where the fuel is sucked from — so don't top up with diesel to thin it.

If you're on a forecourt, whether it's the Esso or the Gulf, ask the attendants to help roll the vehicle away from the pump. At home in Townsend? Then the car stays put.

Stop as soon as it is safe then switch off, if the motor has already run. Come off the M6 — under 5 miles out of Townsend — at the first junction. Distance matters — a short hop across Townsend is a smaller job than driving under 3 miles towards Stoke-on-Trent — so say roughly how far it went.

Townsend: what happens when our technicians get there

By Kingsland CofE Academy, close to Bucknall Methodist Church or on your own drive: wherever the car has stopped, we come to it. Both the work and the quote depend on three replies — what liquid, which amount, and if it's run — so our technicians ask. The quote is given on the call, ahead of any van leaving.

Your system is then purged thoroughly, once your tank is cleared. More than with petrol, it matters here: crystals form, certain metals are attacked, and none of it washes out unaided, however long it sits. The fuel filter is cleaned, or replaced where it needs to be; fresh diesel goes in; and your car is tested. The engine is started next and tested to be sure it runs smoothly, all before our technicians go.

With pumps safe on a working forecourt and quiet enough for use outside a house at night, most jobs in which your motor hasn't run need roughly half an hour after our technicians are there. Payment is on the day, not upfront, and you are given the paperwork an insurer asks for: an engineer's report and a VAT invoice. Wrong-fuel cover is included in plenty of insurance policies — and so make use of the wait to check yours.
