AdBlue in a diesel vehicle: two tanks, two fillers

Diesel goes to the engine — but many modern diesels seen about Wrenthorpe and Kirkhamgate hold another fluid too. Stored in a tank of its own, AdBlue is fed into your exhaust gas and cleans it.

There's a filler on each tank. Plenty of motors share a single flap for the two, whereas others put the AdBlue filler to your boot or under the bonnet. At the petrol pump, the diesel side gets filled constantly. Far less regularly, the AdBlue side gets topped up — normally from a bottle, by a person thinking about where it goes. It's in that gap that the error lives.

How AdBlue in the diesel tank occurs around Wrenthorpe

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

To start with, the warning. Low AdBlue brings a warning from the vehicle, and running out means limp mode — so a hurried top-up, perhaps before work off Jerry Clay Drive, perhaps outside The New Wheel on the way home that evening.

Unfamiliar motors come next, as well. Rentals, new cars and company vehicles put their fillers differently, and habit reaches for the cap used on the old one.

No part stops the pour after it has started, because a bottle with a spout goes into a diesel filler as easily as an AdBlue one. The bottle fits. The same few seconds settle it, in the middle of Wrenthorpe or out in Snow Hill.

Flushing a diesel fuel system after AdBlue, Wrenthorpe

Which filler is for AdBlue, and which for diesel?

A couple of seconds is all the checks take — so run through them before you pour anything, on a drive in Carr Gate or a forecourt around Wrenthorpe.

  • Blue and marking: an AdBlue cap is commonly blue, or says "AdBlue", where a diesel cap usually doesn't. Go by the cap, not where it sits.
  • Look at the size: the smaller filler neck is, on plenty of motors, the AdBlue one.
  • Look inside the fuel flap: many vehicles carry a label there showing which fuel goes where.
  • In your boot or under the bonnet: that's where the filler sits if it is not by the diesel cap, and the handbook tells you which.
  • Ask the person who drove it last — before you leave, not when the light comes on — when you collect a hire or company car from somewhere like the car park outside Outwood.

AdBlue top-ups that never reach your diesel tank

Anywhere in West Yorkshire the light comes on, this is a routine for the day.

  • Not in a rush on the side of Furness Avenue, not on a slope, not with the motor running: park and switch off properly.
  • Find the AdBlue filler and read the cap. Say "AdBlue" out loud as you unscrew it. It sounds silly and it works.
  • The diesel cap remains on. When both share a flap, make sure it is shut before the bottle comes up.
  • Using the bottle's own spout, tip slowly — and stop when it's full or the bottle is empty.
  • Before you start your car, close the cap and check a second time that the diesel cap was never came off.

Find at the second or third stage that AdBlue went in the diesel tank? That's where you stop. Don't go on to step five.

AdBlue in the diesel tank already, around Wrenthorpe?

Don't start the motor: that's where the short order of things starts. On many diesels your ignition alone runs the fuel pump, so do not switch the vehicle on. Filling up with diesel won't weaken it: rather than mixing, AdBlue drops to the base of that tank, right where fuel is taken from.

The staff at Total Energies, EG On the Move or any forecourt will usually help to push the vehicle clear when you ask. If you're on your own drive in Wrenthorpe, leave it where it sits.

Where your motor has been run already, pull over somewhere safe then turn it off. On the M1, under 3 miles from Wrenthorpe, that means the next exit. Distance counts — a quick hop across Wrenthorpe is a smaller job than driving under 3 miles towards Wakefield — so say about how far it went.

Our arrival in Wrenthorpe, and what takes place next

Our engineers come to your car wherever it has stopped, whether that's outside Jerry Clay Academy, near The Well Church (Elim Pentecostal) or on your own driveway. Those replies determine this work and the quote, and so we ask what got in, about how much, and whether it's run. During the call itself, you are told our price — ahead of dispatch.

After that: a drain, then a thorough flush of the entire system. More than with petrol, it matters here: crystals form, certain metals are attacked, and nothing washes away on its own, no matter how long it sits. Testing comes at the end: before that, clean diesel is added, and your filter is cleaned or replaced as needed. We do not go until it has been fired up and is running smoothly.

Unstarted cars usually need a half-hour job after the moment we arrive. The equipment is fine on a busy filling station, and quiet enough for a residential street after dark. You pay on the day, with nothing upfront, and get a VAT invoice and an engineer report for your insurer. While we travel, take a look at your policy; plenty carry cover for misfuelling.
