AdBlue in a diesel car: two tanks, two fillers

Many modern diesels on the roads around Higher Folds and Hindsford carry two liquids, not one. Diesel goes to the engine. Your exhaust, not your motor, is where AdBlue ends up: dosed into the gas to fresh them, from its own tank.

Every tank comes with one filler of its own. Some vehicles put the AdBlue filler in the boot or under the bonnet; plenty of others place both side by side behind one flap. Filling your diesel side at the pump happens constantly. Much less commonly, the AdBlue side is topped up — mostly from a bottle, by someone working out where it goes. Mistakes happen in the gap between the two.

How AdBlue in the diesel tank occurs around Higher Folds

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

The warning comes first. As AdBlue runs low the car tells you, and if it runs out completely, the vehicle goes into limp mode. So the top-up is done in a hurry: on a drive off Royal Drive before work, or in the car park at Higher Folds Sports and Social club on the way home.

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

And the bottle fits. A bottle with a spout goes into a diesel filler as easily as an AdBlue one, and so nothing stops the tip after it has started. Whether it takes place in Bedford or the middle of Higher Folds, it is the same few seconds.

Flushing a diesel fuel system after AdBlue, Higher Folds

Telling the AdBlue filler from your diesel filler

A few seconds is all these take — so run through them before you tip anything, on a drive in Tyldesley or a forecourt in Higher Folds.

  • The cap. The AdBlue cap is commonly blue, or marked "AdBlue". Your diesel cap usually isn't. Read it instead of going by position.
  • 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 cars say there which fuel goes where.
  • Cannot find it beside the diesel filler? In that case check below the bonnet or inside the boot — the handbook says which.
  • The person who drove the vehicle last. On a hire or company car picked up from somewhere like the car park outside Atherton, ask before you leave, not when the light comes on.

Keeping AdBlue out of the diesel tank when you top up

For the day the warning comes on — wherever you are around Greater Manchester — a routine to follow.

  • Park and switch off. Not on a slope, not with the motor running, and not in a rush on the side of Regina Crescent.
  • Say "AdBlue" out loud as you unscrew the cap, after you find the AdBlue filler and read it. Silly, perhaps, yet it works.
  • The diesel cap stays on. Where both share a flap, make sure it's closed before lifting the bottle.
  • Finish when the tank is topped up or the bottle runs dry; until then, pour slowly through its own spout.
  • Shut the cap, then check again — confirm your diesel cap stayed shut the whole time. After that, start the vehicle.

Spot at stage two or three that it has already gone into your diesel side? Then stop right there. Don't go on to step five.

Already put AdBlue in your diesel tank around Higher Folds?

The short order of things, starting with not starting your motor. The fuel pump starts on many diesels as soon as your ignition is switched on — and so keep it off. Diluting it with extra diesel won't work, because AdBlue sinks to the bottom instead of mixing — and that is where your fuel is drawn from.

On a forecourt — Tesco, Texaco or another — the attendants will usually help roll the car away, when you ask. At home in Higher Folds? Then your car stays put.

Where the motor has been run already, pull over safely and switch the car off. Come off the M61 — under 5 miles out of Higher Folds — at the next exit. A short hop across Higher Folds is a smaller job than a run towards Salford, under 10 miles away, so tell us about how far it went.

What takes place when we turn up around Higher Folds

The van reaches the car wherever it stopped — your own drive, near Wood End Pit AKA Bedford Colliery marker stone, former coal mine., or by St Gabriel's Catholic Primary School. Both the work and our price depend on three replies — what fluid, which amount, and if it has run — so our engineers ask. During the call itself, you are told the price — ahead of anything else.

Then your tank is cleared and the system cleaned thoroughly. AdBlue crystallises and is corrosive to some of the metals in a fuel system, and so it doesn't wash out on its own — which is why that counts more with AdBlue than with petrol. Filter cleaned or, if needed, swapped; fresh diesel in; then a test of the car. We don't leave until it has been fired up and is running correctly.

With pumps safe on a busy forecourt and quiet enough for use outside a house at night, most jobs where the motor has not run need roughly half an hour once our engineers arrive. You pay on the day, with nothing upfront, and get a VAT invoice and an engineer report for your insurer. Plenty of insurance policies include misfuelling cover, so it is worth checking yours while we are on the way.
