AdBlue in a diesel motor: two tanks, two fillers

Diesel feeds the motor — but many newer diesels driven about Fryerns and Chalvedon carry a second liquid as well. Stored in a tank of its own, AdBlue is fed into your exhaust gas to clean it.

Separate tanks, separate fillers. Some motors keep the AdBlue filler in the boot or under the bonnet; plenty more place both side by side behind one flap. Diesel goes in on every filling station visit, week in, week out. Much less often, the AdBlue side gets topped up — normally from a bottle, by a person working out where it goes. Mistakes happen in that gap between the two.

Fryerns: how AdBlue in the diesel tank takes place

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

First, the warning. Low AdBlue triggers a warning from your car, and letting it run out leads to limp mode — hence a rushed top-up, perhaps before work off The Fremnells, perhaps outside The Jolly Friar on the way home after work.

Unfamiliar cars are second, as well. Rentals, new motors and company vehicles put their fillers differently, and habit goes for the cap it used on the old one.

A spout-topped bottle meets no resistance at a diesel filler any more than at an AdBlue one. And so the pour, after started, carries on. Barstable or the middle of Fryerns: it is the same few seconds either way.

The AdBlue filler and the diesel filler: telling them apart

Before you pour anything, whether on a drive in Kingswood or a forecourt in Fryerns, check these. They take a few seconds.

  • The cap. The AdBlue cap is regularly blue, or marked "AdBlue". Your diesel cap normally isn't. Read it instead of going by position.
  • On many cars, size tells: AdBlue gets the smaller filler neck.
  • Check inside the fuel flap: many motors carry a label there saying which fuel goes where.
  • In your boot or under the bonnet: that is where the filler sits if it's not by your diesel cap, and the handbook tells you which.
  • Picking up a hire or company car, perhaps at the car park outside Basildon? Ask the person who drove the car last before you set off, rather than once the light comes on.

AdBlue top-ups that never reach the diesel tank

Anywhere across Essex the light comes on, here is a routine for that day.

  • Not in a rush on the side of Gay Bowers, not on a slope, not with the motor running: park and switch off properly.
  • Say "AdBlue" out loud as you unscrew the cap, after you find the AdBlue filler and read it. Daft, yes, yet it does the trick.
  • Leave the diesel cap on. If both sit under one flap, check your diesel cap is still closed before you lift the bottle.
  • Stop when the tank is topped up or the bottle runs dry; until then, tip gently using the own spout.
  • Only then, start the vehicle: close the cap, check again, and make sure your diesel cap was never opened.

Find at stage two or three that it has already gone into your diesel side? Then stop right there. Step five stays off limits.

Fryerns: already put AdBlue in your diesel tank?

Brief order, then. First: your engine remains off. The fuel pump starts on plenty of diesels as soon as the ignition is switched on — so keep it off. Thinning it with more diesel fails, because AdBlue settles to the base rather than blending — and that's where the fuel is pulled from.

If you're on a forecourt, whether it's the Texaco or the Asda, ask the attendants to help roll the car away from the petrol pump. Your own driveway in Fryerns is the place it should stay.

Already started? Stop when it's safe, then turn off. The next exit means where to come off when you are on the M25, under 10 miles from Fryerns. Distance matters — a quick hop across Fryerns is a smaller job than driving under 15 miles towards Southend-on-Sea — so tell us roughly how far it went.

Our arrival around Fryerns, and what occurs next

Our technicians come to your car wherever it has stopped, whether that's outside The Willows Primary School, near Fryerns Library or on your own drive. Our technicians ask what went in, about how much, and whether it's run, because those replies decide the work and the price. During the call itself, you are told our quote — ahead of dispatch.

Your system is then purged thoroughly, after that tank is emptied. Unlike petrol, AdBlue leaves crystals and eats at certain fuel-system metals, and none of it clears out unaided. Hence it matters more. Once your filter has been flushed — or renewed, where required — fresh diesel is added, and finally your car is tested. Before we go, our technicians start it and check that it's running properly.

Most jobs are done in roughly half an hour after our technicians arrive, provided the engine has not run — and the pumps our technicians use are safe on a busy forecourt yet quiet at night outside a house. Payment happens on the day, not upfront, and you receive the documents your insurer asks for: an engineer's report and a VAT invoice. Misfuelling cover is part of many insurance policies — and so use the wait to look at yours.
