Avoiding AdBlue in a Diesel Tank in Polsloe Bridge: Why It Occurs

Two fillers, two tanks: AdBlue in a diesel motor

Diesel feeds the motor — but many current diesels driven about Polsloe Bridge and Stoke Hill hold a second fluid as well. Kept in a tank of its own, AdBlue is sprayed into your exhaust stream and cleans it.

There's a filler for each tank. Some cars put the AdBlue filler in your boot or under the bonnet; a lot more have both side by side under one flap. The diesel side is topped up at the pump all the time. The AdBlue side is fuelled far less frequently, normally from a bottle, and normally by somebody who has to stop and think where it goes. The mistake grows in that gap between the two.

Polsloe Bridge: how AdBlue in your diesel tank happens

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

On a driveway off Monks Road before work, or in the car park at The Queens Head heading home: that is where the rushed top-up happens. Why the rush? As AdBlue runs low the vehicle tells you, and once it's gone, limp mode kicks in.

Then, your hand goes for the cap it would have used on the old car — because a hire car, a new vehicle or a company car puts the fillers where your last one did not.

Third, the spout fits: a diesel filler or AdBlue one, it goes in as easily, and once the pour begins, nothing halts it. It's seconds, whether out in Polsloe Priory or right in the heart of Polsloe Bridge.

Flushing a diesel fuel system after AdBlue, Polsloe Bridge

Telling the AdBlue filler from your diesel filler

Whether a Polsloe Bridge forecourt or a driveway out in St James, take a few seconds on these before any is poured in.

  • Where it sits misleads; the cap doesn't. AdBlue ones are often blue or carry the name "AdBlue" — diesel caps normally don't.
  • The size. On many cars the AdBlue filler neck is the smaller of the two.
  • Lift the filler flap and check for a label — plenty of motors show what belongs in which filler just there.
  • The handbook. If your filler isn't by the diesel cap, it is in your boot or under the bonnet, and the handbook says which.
  • The person who drove it last. On a hire or company car collected from somewhere like the car park at the nearest station, ask before you leave, not when the light comes on.

Keeping AdBlue out of your diesel tank when you top up

The day the light comes on, wherever around Devon, follow this routine.

  • Turn off after you park — flat ground, motor stopped, and not rushed by Hamlin Lane on the verge.
  • Say "AdBlue" out loud as you unscrew the cap, after you find the AdBlue filler and read it. Daft, yes, but 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.
  • Finish when that tank fills or the bottle runs dry; before that, pour slowly through the built-in spout.
  • Shut the cap, and check once more — making sure your diesel cap stayed closed the whole time. Only then, start the car.

Find during the second or third step that AdBlue went into the diesel filler? That is where you stop. Skip stage five altogether.

AdBlue in the diesel tank already, in Polsloe Bridge?

Brief order, then. Top of that: your engine remains unstarted. Do not switch the ignition on; on many diesels that alone runs the fuel pump. Filling up with diesel will not thin it: rather than mixing, AdBlue sinks to the base of your tank, right where the fuel is taken from.

At a forecourt — Morrisons, Esso or another — the attendants will normally help push the car clear, if you ask. On your own drive around Polsloe Bridge? Then the car remains where it is.

When your engine has run by now, pull over somewhere safe and turn it off. The next exit means where to leave when you're on the M5, under 3 miles from Polsloe Bridge. A short hop across Polsloe Bridge is a smaller job than a run towards Exeter, under 3 miles away, so tell us about how far it went.

Polsloe Bridge: what happens when our engineers arrive

We come to the vehicle wherever it has stopped, whether that is outside Ladysmith Junior School, close to Pinhoe Road Baptist Church or on your own drive. Those replies settle this work and the quote, so our technicians ask what went in, about how much, and if it's run. That quote comes over the phone, before any van leaves.

Then the tank is drained and the system flushed thoroughly. Unlike petrol, AdBlue leaves crystals and eats at some fuel-system metals, and neither washes away by itself. Hence it counts more. A test comes at the end: before that, fresh diesel goes in, and the fuel filter is cleaned or replaced as needed. We don't leave until it has been fired up and is running properly.

Most jobs are finished in roughly half an hour once our technicians get there, provided your engine hasn't run — and the pumps we use are safe on a busy forecourt and quiet after dark outside a house. Nothing in advance; you settle up on the day. Afterwards, the VAT invoice and a report from the engineer go to you for your insurer. Plenty of insurance policies include misfuelling cover, so it's worth checking yours while we are on the way.

The car does not need to shift. Our technicians drain it where it is — a side street close to World War II Graves Memorial, a lay-by on the way to Hamlin Lane Playing Fields, a driveway. Awkward to pin down, like the back of St Katherine's Priory? By a county line? Asking beats assuming, so phone.
