Two fillers, two tanks: AdBlue in a diesel motor

Diesel feeds your motor — yet plenty of modern diesels seen around Roughtown and Sandbed carry a second liquid too. AdBlue goes to your exhaust, where it is sprayed into the gas to fresh it, and it lives in a tank of its own.

Each tank has its own filler. On a lot of motors the two sit side by side under the same flap; on others the AdBlue filler is in the boot or under the bonnet. The diesel side is fuelled at the petrol pump all the time. A driver who has to stop and think where it goes usually tops up the AdBlue side, from a bottle, and far less regularly. The error lives in that gap.

Roughtown: how AdBlue in your diesel tank happens

It's rarely carelessness. Three things tend to line up.

First, the warning. Low AdBlue triggers a message from the vehicle, and running out leads to limp mode — so a rushed top-up, perhaps before work off High Street, perhaps outside Church Inn on the way home that evening.

Next, the hand reaches for the cap it knew on the old vehicle — because a hire car, a new car or a company car puts the fillers where your last one didn't.

Third, the spout fits: diesel filler or AdBlue filler, it goes in just as easily, and after the pour begins, no part halts it. Whether it happens in Woodend or the middle of Roughtown, it's the same few seconds.

Flushing a diesel fuel system after AdBlue, Roughtown

Which filler is for AdBlue, and which for diesel?

Look at these before pouring, on a forecourt in Roughtown or a drive over in Brook Bottom. Seconds, that's all.

  • Blue and marking: an AdBlue cap is often blue, or says "AdBlue", where a diesel cap normally does not. Go by the cap, not its position.
  • Look at the size: the smaller filler neck is, on plenty of motors, the AdBlue one.
  • Lift the flap and check for a label — many vehicles show what belongs in which filler just there.
  • In the boot or under the bonnet: that is where the filler sits if it is not by the diesel cap, and the handbook tells you which.
  • The person who drove the vehicle last. On a hire or company car picked up from somewhere like the car park at Mossley (Manchester), ask before you leave, not when the light comes on.

AdBlue top-ups that never reach the diesel tank

A routine for the day the light comes on, wherever around Greater Manchester that is.

  • Turn off after you park — flat ground, engine stopped, and never rushed beside Roughtown Road on the verge.
  • Say "AdBlue" out loud as you unscrew the cap, after finding the AdBlue filler and reading it. Silly, yes, yet it works.
  • If both sit under one flap, check your diesel cap is still closed before you lift the bottle — then leave the vehicle on.
  • Using the bottle's own spout, pour slowly — and stop when it is full or the bottle is empty.
  • Close the cap and check again. Make sure your diesel cap was never opened. Only then start the car.

Discover during the second or third stage that the bottle went in the diesel tank? That's where you stop. Stage five is off limits.

Already put AdBlue in your diesel tank around Roughtown?

Short list, then. First: your motor remains off. The fuel pump starts on many diesels the moment the ignition is switched on — and so leave it off. Don't top up with diesel to thin it: AdBlue doesn't mix with diesel, it sinks to the bottom of your tank, where the fuel is drawn from.

At a forecourt — Gulf, Texaco or any other — the staff will usually help push the vehicle clear, when you ask. If you are on your own drive around Roughtown, leave the car where it sits.

Already started? Stop when it's safe, then switch off. The next exit means the place to come off when you are on the M60, under 5 miles from Roughtown. Distance counts — a quick hop across Roughtown makes a smaller job than driving under 10 miles to Manchester — so say about how far it went.

When our engineers get there in Roughtown, what occurs?

By Milton St John's CofE Primary School, near St John the Baptist or on your own driveway: wherever the car has stopped, we come to it. Both the work and our price rest on three replies — what liquid, what amount, and whether it's run — so our technicians ask. You get that quote by phone, before anybody heads out.

After that: a drain, then a thorough flush of the whole system. More than with petrol, it matters with AdBlue: the crystals form, certain metals corrode, and nothing clears out unaided, however long it is left. The filter flushed or, where needed, swapped; clean diesel in; then a check of the car. We do not go until it has been started and is running properly.

If the motor hasn't run, the majority of jobs take about half an hour once we're there, using pumps that are safe on a busy forecourt and quiet enough to use outside a house after dark. Your insurer will ask for the engineer's report and the VAT invoice, and both are yours once the job is done. Payment is on the day, with no money upfront. Before we get there, take a look at your insurance documents; plenty carry cover for misfuelling.
