AdBlue in a Diesel Tank in Stanycliffe: Why It Happens and How to Avoid It

Caught before your engine runs, it is normally a drain and a thorough flush, done where the car is in Stanycliffe. The rest of this page covers why it occurs and how to ensure it doesn't — useful if you're reading before it has happened.

Why does AdBlue in a diesel car need its own filler?

Diesel feeds your engine — yet many modern diesels seen about Stanycliffe and Top of Hebers hold another fluid as well. AdBlue goes to the exhaust, where it is sprayed into the gas to clean it, and it lives in a tank of its own.

Each tank has its own filler. Plenty of motors have a single flap for both, whereas some put the AdBlue filler to your boot or under the bonnet. At the pump, your diesel side gets filled all the time. A driver who has to stop and work out where it goes usually tops up the AdBlue side, from a bottle, and far less frequently. It's in the gap that the error lives.

How does AdBlue in the diesel tank occur around Stanycliffe?

Carelessness rarely explains it. Instead is three things lining up at once.

The warning comes first. As AdBlue runs low your car tells you, and if it runs out completely, the vehicle drops into limp mode. So the top-up is done in a hurry: on a driveway off Stanycliffe Lane before work, or in the car park outside The Cotton Tree on the way home.

Then, your hand goes for the cap it would have used on the old motor — since a hire car, a new vehicle or a company car puts the fillers where your last one didn't.

Nothing stops the pour after it has started, since a bottle with a spout goes into a diesel filler as readily as an AdBlue one. The bottle fits. Whether it takes place in Hollins or the middle of Stanycliffe, it is the same few seconds.

Telling the AdBlue filler from your diesel filler

A few seconds is all these take — so run through them before you pour anything, on a drive in Acres or a forecourt in Stanycliffe.

  • Position can mislead; the cap doesn't. AdBlue caps tend to be blue or bear the word "AdBlue" — diesel ones normally do not.
  • On plenty of motors, the size tells: AdBlue has the smaller filler neck.
  • Open the flap and look for a label — many motors show what belongs in each filler just there.
  • The handbook. If the filler is not by the diesel cap, it is in your boot or under the bonnet, and the handbook says which.
  • Whoever had it before knows. Check as you pick up a rental or fleet car — from Mills Hill's car park, say — rather than once the warning appears.

Topping up AdBlue without it reaching your diesel tank

Wherever in Greater Manchester the light comes on, here is a routine for that day.

  • Pull in somewhere level, engine off, with time to spare — not hurried on the side of Rochdale Road.
  • Say "AdBlue" out loud as you unscrew the cap, after finding the AdBlue filler and reading it. Silly, yes, but it works.
  • Both behind one flap? Then make sure the cap on the diesel filler stays closed before lifting the bottle.
  • Stop once that tank fills or the bottle is empty; until then, pour slowly using the own spout.
  • Before starting the vehicle, shut the cap and look again that the diesel cap never came off.

If at step two or three you find you have already poured into the diesel side, stop there. Stage five stays out.

Already put AdBlue in your diesel tank around Stanycliffe?

Do not start the engine: that is how the short order of things begins. The fuel pump starts on plenty of diesels the moment the ignition goes on — so keep it off. Diluting it with extra diesel fails, since AdBlue settles to the bottom rather than mixing — and that's where the fuel is pulled from.

If you're on a forecourt, whether it's the BP or the Esso, ask the attendants to help push the vehicle clear of the pump. Leave it where it is if you're on your own driveway in Stanycliffe.

Already started? Stop once it's sensible, then switch off. Come off the Slattocks Link Road — under a mile out of Stanycliffe — at the first exit. Mileage counts — a quick hop across Stanycliffe makes a smaller job than driving under 10 miles towards Manchester — so say roughly how far it went.

When our technicians turn up in Stanycliffe, what occurs?

Our engineers come to your car wherever it has stopped, whether that's outside Boarshaw Community Primary School, close to Greater Manchester North Scouts or on your own driveway. Both the work and the quote rest on three replies — what fluid, which amount, and whether it has run — so our technicians ask. No one sets off until you've had the price by phone.

The fuel system is then cleaned thoroughly, once that tank is emptied. Not like petrol, AdBlue forms crystals and attacks certain fuel-system metals, and neither washes away unaided. That is why it counts more. Filter cleaned or, where it must be, swapped; fresh diesel in; and then a test of your vehicle. We don't leave until it has been fired up and is running properly.

Unstarted cars usually need a half-hour visit from arrival. The equipment is safe on a live filling station, and quiet enough for a residential street late at night. You pay on the day, with nothing upfront, and get a VAT invoice and an engineer report for your insurer. Many insurance policies include misfuelling cover, so it's worth checking yours while we are on the way.
