A drain plus a full flush, done right where the vehicle sits around Harwood Bar, is normally what it needs when caught before the motor runs.

AdBlue in a diesel car: two tanks, two fillers

Plenty of modern diesels in Cliffe, like those in Harwood Bar, carry on two fluids; your engine takes just the diesel. The exhaust, not the motor, is where AdBlue ends up: sprayed into the fumes to fresh them, from its own tank.

Separate tanks, different fillers. Under one flap, side by side: that is the layout on many vehicles. On others, AdBlue's filler is beneath the bonnet or in your boot instead. At the pump, the diesel side is topped up all the time. Far less commonly, the AdBlue side is topped up — normally from a bottle, by a person working out where it goes. That gap is where the error lives.

How does AdBlue in your diesel tank take place around Harwood Bar?

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

Haste comes from the warning. Your car warns you as AdBlue runs low, and a dry tank puts the vehicle into limp mode — so the top-up gets done in a rush, before work on a driveway off Harwood New Road, or heading home in the car park at Park Hotel.

Next, the hand goes for the cap it would have used on the old motor — since a rental car, a new car or a company car places the fillers where your last one did not.

No part stops the tip once it has started, since a bottle with a spout goes into a diesel filler as readily as an AdBlue one. The bottle fits. It takes a few seconds, whether out in Hyndburn Bridge or right in the heart of Harwood Bar.

Flushing a diesel fuel system after AdBlue, Harwood Bar

Which filler is for AdBlue, and which for diesel?

Be it a Harwood Bar forecourt or a drive out in Great Harwood, take a couple of seconds on these before anything is poured in.

  • Read the cap instead of going by where it sits: AdBlue ones are commonly blue or marked "AdBlue", and diesel caps normally aren't.
  • Check the size: the smaller neck is, on many vehicles, the AdBlue one.
  • The flap. Look inside the fuel flap for a label. Many motors say there which fuel goes where.
  • Can't see it beside the diesel filler? Then look below the bonnet or inside your boot — the owner's manual says which.
  • The person who drove it last. On a hire or company car picked up from somewhere like the car park at Huncoat, ask before you leave, not when the light comes on.

How to top up without AdBlue in your diesel tank

A routine for the day the light comes on, wherever in Lancashire that is.

  • Stop on level, engine off, with time to spare — not rushing on the side of Harwood Lane.
  • Find the AdBlue filler and read the cap. Say "AdBlue" out loud as you unscrew it. It sounds silly and it works.
  • Both behind a single flap? So confirm the lid on your diesel filler stays shut before raising the bottle.
  • Tip slowly, using the bottle's own spout. Stop when it's full or when the bottle is empty.
  • Shut the cap, and check once more — confirm your diesel cap stayed shut throughout. After that, start your car.

If at stage two or three you find you have already poured into the diesel side, stop there. Never carry on to step five.

Harwood Bar: already put AdBlue in the diesel tank?

Then the order of things is short. Do not start your motor. Don't switch the ignition on; on plenty of diesels that alone runs the fuel pump. AdBlue does not mix with diesel — it sinks to the bottom of your tank, where your fuel is pulled from — so do not top up with diesel to dilute it.

At a forecourt — Texaco, Ridings Auto Services or any other — the attendants will usually help push the vehicle clear, if you ask. Your own driveway in Harwood Bar is the place it should stay.

Where the engine has run by now, stop somewhere safe and turn the vehicle off. On the M65, under 3 miles from Harwood Bar, that means the next junction. A short hop across Harwood Bar is a smaller job than a run towards Preston, under 15 miles away, and so tell us roughly how far it went.

Harwood Bar: what takes place when our engineers arrive

We come to your car wherever it has stopped, whether that's outside St Hubert's Roman Catholic Primary School, Great Harwood, near Martholme Viaduct or on your own driveway. We ask what was put in, about how much, and whether it's run, because those answers decide the work and the price. That price comes on the call, ahead of any van leaving.

The system is then rinsed thoroughly, once that tank is emptied. Not like petrol, AdBlue forms crystals and eats at some fuel-system metals, and none of that clears out by itself. Hence it counts more. A test comes last: before that, clean diesel is added, and the filter is flushed or changed as needed. We do not leave until it has been started and is running smoothly.

With pumps fine on a busy forecourt and quiet enough to use outside a house at night, most jobs where your motor hasn't run take roughly half an hour after our technicians are there. Your insurer usually wants the engineer's report and your VAT invoice, and both are yours at the end. Payment is on the day, with no deposit. It is worth looking at your policy as the van travels to you: misfuelling cover comes with plenty of policies.
