Two fillers, two tanks: AdBlue in a diesel car

Diesel feeds the motor — yet plenty of newer diesels driven round Low Spennymoor and Spennymoor carry a second fluid too. Kept in a tank of its own, AdBlue is fed into your exhaust gas to clean it.

Each tank has its own filler. Plenty of vehicles have a single flap for the two, whereas some move the AdBlue filler to the boot or under the bonnet. Filling the diesel side at the pump happens constantly. Much less commonly, the AdBlue side gets filled — mostly from a bottle, by someone thinking about where it goes. That gap is where the slip lives.

How AdBlue in your diesel tank takes place around Low Spennymoor

Carelessness seldom causes it. What does is three things lining up together.

To start with, the warning. Low AdBlue triggers a warning from the car, and running out leads to limp mode — so a hurried top-up, maybe before work off Coulson Street, perhaps at The Frog & Ferret on the way home after work.

The old car's cap is where the hand goes — yet a hire car, a new car or a company car keeps the fillers elsewhere. That's a second factor: a new car.

No part stops the tip once it has started, since a bottle with a spout goes into a diesel filler as readily as an AdBlue one. The bottle fits. It's a few seconds, be it in Mount Pleasant or right in the centre of Low Spennymoor.

How to tell the AdBlue filler from the diesel one

Whether a Low Spennymoor forecourt or a drive out in Tudhoe, take a few seconds over these before anything is poured in.

  • Where it sits misleads; the cap does not. AdBlue ones tend to be blue or bear the word "AdBlue" — diesel caps usually don't.
  • The size. On plenty of vehicles the AdBlue filler neck is the smaller of the two.
  • The flap. Look inside the fuel flap for a label. Plenty of vehicles say there which fuel goes where.
  • In the boot or under the bonnet: that's where the filler is if it's not by your diesel cap, and the handbook says which.
  • 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 Bishop Auckland.

Keeping AdBlue out of your diesel tank when you top up

For the day the light comes on — wherever it is around Durham — a routine to use.

  • Turn off after you park — level ground, engine stopped, and not rushed beside Woodward Road at the roadside.
  • Say "AdBlue" out loud as you unscrew the cap, after finding the AdBlue filler and read it. Daft, perhaps, but it does the trick.
  • The diesel cap remains on. Where the two share a flap, confirm it's shut before lifting the bottle.
  • Gently is best, through the bottle's own spout, till 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.

If at step two or three you find you have already poured into the diesel side, stop there. Leave out step five altogether.

Put AdBlue in your diesel tank in Low Spennymoor already?

Short order, then. Top of it: your motor remains unstarted. The fuel pump starts on plenty of diesels as soon as the ignition goes on — so keep it off. AdBlue does not mix with diesel — it sinks to the bottom of that tank, where your fuel is drawn from — so do not top up with diesel to thin it.

If you're on a forecourt, whether it's the Asda or the BP, ask the staff to help roll your car away from the pump. Leave it where it is if you are on your own driveway around Low Spennymoor.

When the engine has run already, pull over somewhere safe then switch it off. Come off the A1(M) — under 3 miles out of Low Spennymoor — at the next junction. Mileage matters — a quick hop across Low Spennymoor is a smaller job than driving under 10 miles to Durham — so say about how far it went.

What occurs when our technicians turn up in Low Spennymoor

By North Park Primary School, close to Mount Pleasant Independent Methodist Church or on your own driveway: wherever the car has stopped, our technicians come to it. Which fluid got in, the amount, and whether it ran: our engineers ask because the answers decide the work and quote. The quote comes on the call, ahead of any van leaving.

Draining that tank comes next, followed by a thorough flush of the system. Unlike petrol, AdBlue leaves crystals and eats at certain fuel-system metals, and none of that clears out by itself. That is why it counts more. A test is at the end: before that, fresh diesel goes in, and the filter is flushed or changed if necessary. After that we fire it up and check it runs properly before we go.

Most jobs are finished in roughly half an hour after our engineers get there, as long as your engine hasn't run — and the pumps our engineers use are safe on a live forecourt yet quiet after dark outside a house. Paying happens on the day, not upfront, and you receive the paperwork your insurer asks for: an engineer report and a VAT invoice. It's worth checking your policy while we travel to you: misfuelling cover is included with many policies.
