Grimethorpe: How Does AdBlue End Up in a Diesel Tank, and How Do You Prevent It?

Keep your engine and ignition off then call 0333 366 0103 first — reading can wait when AdBlue is already in the diesel tank. Caught before your engine runs, it's generally a drain and a thorough flush, done where the car is in Grimethorpe. The rest of this page explains why it happens and how to make sure it does not — useful if you're reading before it has happened.

Two fillers, two tanks: AdBlue in a diesel car

Diesel goes to your motor — but many modern diesels driven about Grimethorpe and Brierley carry another 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. Many of motors have a single flap for the two, while others put the AdBlue filler to your boot or under the bonnet. Diesel goes in on each filling station visit, again and again. A driver who has to stop and think where it goes normally tops up the AdBlue side, from a bottle, and much less frequently. That gap is where the slip lives.

How does AdBlue in the diesel tank take place in Grimethorpe?

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

On a driveway off Queensway before work, or in the car park outside The Old Club on the way home: that's where the rushed top-up takes place. Why the rush? As AdBlue runs low the vehicle tells you, and if it's empty, limp mode follows.

Then the car is strange. A hire car, a new vehicle or a company car puts the fillers where your last one did not, and your hand hits for the cap it would have used on the old one.

A spouted bottle finds no obstacle at a diesel filler no more than at an AdBlue one. And so the tip, once started, keeps on. It's a few seconds, be it out in Belle Green or bang in the heart of Grimethorpe.

Flushing a diesel fuel system after AdBlue, Grimethorpe

Which filler is for AdBlue, and which for diesel?

Look at these first, on a forecourt in Grimethorpe or a driveway over in Upper Cudworth. Seconds, that's all.

  • Position can mislead; the cap does not. AdBlue caps tend to be blue or carry the word "AdBlue" — diesel caps usually don't.
  • The size. On many cars the AdBlue filler neck is the smaller of the two.
  • A label inside your fuel flap frequently shows which fuel goes where, on plenty of vehicles. Look for it.
  • In your boot or under the bonnet: that is where the filler is if it's not by your diesel cap, and the handbook says which.
  • The previous driver knows. Ask when you collect a hire car or company car — at Moorthorpe's car park, perhaps — rather than when the light comes on.

Keeping AdBlue out of your diesel tank when you top up

Anywhere around South Yorkshire the light comes on, this is a routine for that day.

  • Park and switch off. Not on a slope, not with the motor running, and not in a rush on the side of High Street.
  • Daft as it sounds, saying "AdBlue" aloud as you unscrew the cap does the trick — after you've found the filler and read the cap.
  • The two under a single flap? So confirm the lid on your diesel side stays closed before lifting the bottle.
  • Using the bottle's own spout, tip slowly — and stop when it is full or the bottle is empty.
  • Only after that, start the car: close the cap, check a second time, and make sure the diesel cap was never opened.

Discover during the second or third step that the bottle went into the wrong tank? That is where you stop. Never go on to stage five.

AdBlue in your diesel tank already, in Grimethorpe?

The short order of things, beginning with not starting the motor. The fuel pump starts on plenty of diesels as soon as the ignition is switched on — and so leave it off. Diluting it with more diesel fails, since AdBlue sinks to the base rather than blending — and that's where the fuel is sucked from.

If you're on a forecourt, whether it's the the nearest petrol station or the Stay Warm Solid Fuels LTD, ask the staff to help roll the car clear of the pump. At home in Grimethorpe? So your car remains put.

Already run? Pull over when it's sensible, then turn off. The next exit is the place to leave when you're on the M1, under 10 miles from Grimethorpe. A short hop across Grimethorpe is a smaller job than a run towards Wakefield, under 10 miles away, and so tell us about how far it went.

Our arrival around Grimethorpe, and what takes place next

The van comes to your car anywhere it has come to rest — your own drive, near Grimethorpe War Memorial, or by Ladywood Primary School. Which fluid was put in, the amount, and whether it ran: we ask since those replies set both work and quote. On the phone call itself, you hear our price — ahead of anything else.

Then that tank is cleared and the system purged thoroughly. AdBlue crystallises and is corrosive to some of the metals in a fuel system, so it does not wash out on its own — which is why that matters more here than with petrol. Once your filter has been flushed — or renewed, where needed — clean diesel is added, and then the vehicle is tested. Next our technicians fire it up and confirm it runs smoothly before we leave.

Unstarted cars usually need a half-hour visit from the moment we arrive. The equipment is fine on a live filling station, and hushed enough for a residential street late at night. Payment happens on the day, not upfront, and you are given the paperwork your insurer asks for: an engineer report and a VAT invoice. Plenty of insurance policies include misfuelling cover, so it is worth checking yours whilst we are on the way.
