AdBlue in a diesel motor, and its separate tank

Plenty of newer diesels around Little Marton Moss Side, as well as Walkers Hill, run on two liquids; the engine takes just the diesel. AdBlue goes to the exhaust, where it is sprayed into the gas to fresh it, and it lives in a tank of its own.

There is a filler for each tank. On a lot of vehicles the two sit side by side under the same flap; on others the AdBlue filler is in the boot or under the bonnet. Diesel gets filled on every forecourt visit, week in, week out. The AdBlue side is filled far less often, normally from a bottle, and usually by a person who has to stop and think where it goes. It's in the gap that the error happens.

AdBlue in your diesel tank in Walkers Hill: how it occurs

Carelessness seldom causes it. Instead is three things coming up at once.

On a driveway off Corbridge Close before work, or in the car park outside The Cherry Tree on the way home: that is where the hurried top-up takes place. What is the reason for the rush? As AdBlue gets low the car tells you, and once it's empty, limp mode kicks in.

The old car's cap is where your hand reaches — yet a rental car, a new vehicle or a company car puts the fillers somewhere else. That is a second thing: a new car.

Third, the spout fits: a diesel filler or AdBlue filler, it slides in as readily, and once the pour begins, nothing stops it. Whether it happens in Marton Moss Side or the middle of Walkers Hill, it's the same few seconds.

Flushing a diesel fuel system after AdBlue, Walkers Hill

The AdBlue filler and the diesel filler: telling them apart

Look at these first, on a forecourt around Walkers Hill or a drive over in Great Marton Moss. Seconds, no more.

  • Blue and marking: an AdBlue cap is regularly blue, or says "AdBlue", where a diesel cap usually doesn't. Trust the cap, not where it sits.
  • Check the size: the smaller filler neck is, on plenty of motors, the AdBlue one.
  • A label inside your fuel flap often says which fuel goes where, on plenty of vehicles. Look for it.
  • In the boot or under the bonnet: that is where the filler sits if it is not by your diesel cap, and the handbook says which.
  • The person who drove it last. On a hire or company car collected from somewhere like the car park outside Blackpool South, ask before you leave, not when the light comes on.

Keeping AdBlue out of your diesel tank when you top up

When the light goes on, anywhere across Lancashire, use this routine.

  • Turn off after you park — level ground, engine stopped, and never rushed by Carterville Close on the verge.
  • Say "AdBlue" out loud as you unscrew the cap, once you find the AdBlue filler and read it. Silly, yes, but it works.
  • If both sit under one flap, check your diesel cap is still closed before you lift the bottle — then leave it on.
  • Tip slowly, using the bottle's own spout. Stop when it is full or when the bottle is empty.
  • Shut the cap, and check again — confirm the diesel cap remained closed throughout. After that, start the car.

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

Put AdBlue in the diesel tank around Walkers Hill already?

Don't start your engine: that is how the short order of things begins. Don't switch the ignition on; on many diesels that alone runs the fuel pump. Thinning it with extra diesel won't work, because AdBlue sinks to the base instead of mixing — and that's where your fuel is pulled from.

Ask the staff to help roll the vehicle clear of the pump if you're on a forecourt — the Asda, the Shell or somewhere else. Your own driveway around Walkers Hill is where it stays.

When the motor has been run already, pull over safely and switch the vehicle off. Walkers Hill sits under 3 miles from the M55; there, use the first exit. About how far did it go? Crossing Walkers Hill is smaller work than a trip of under 15 miles to Preston, so say.

What occurs when our engineers arrive around Walkers Hill

The van comes to the vehicle wherever it has come to rest — your own driveway, near Marton Methodist Church, or outside Marton Primary Academy and Nursery. We ask what was put in, roughly how much, and whether it has run, since the replies determine this work and the quote. The quote is given on the call, before any van leaves.

The fuel system is then purged thoroughly, once your tank is cleared. Much more than with petrol, it matters here: the crystals build up, some metals corrode, and nothing clears away on its own, however long it is left. After the fuel filter has been cleaned — or renewed, where required — clean diesel goes in, and finally your vehicle gets tested. Before we go, our technicians fire it up and confirm that it is running properly.

Most jobs are done in roughly half an hour once our technicians get there, provided your motor has not run — and the pumps our technicians use are safe on a live forecourt yet quiet at night outside a house. You pay on the day, with nothing upfront, and get a VAT invoice and an engineer report for your insurer. Misfuelling cover is included in plenty of insurance policies — so make use of the wait to look at yours.

AdBlue drains across Lancashire, Walkers Hill included

Common Edge and Hawes Side are among the towns near Walkers Hill, a residential suburb, that the same vans cover, over FY postcodes. A postcode starting FY4 5 gets our van to you fastest.

Your car stays where it is. We drain it where it is — a side street close to Aysgarth Court Community Centre, a lay-by on the way to Bridge House Road Playing Field, a driveway. Tricky to pin down, like the back of Planet Kaos Play Centre? Close to a county line? Checking is better than assuming, and so ring.

In short, for Walkers Hill people

Read the cap before you tip. Petrol in Diesel empties it on the spot, anywhere around Lancashire, if AdBlue has gone in the diesel tank regardless — so leave the vehicle off then call 0333 366 0103.
