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

Pause reading a minute if the diesel tank already has AdBlue in it: ignition off, motor off, then ring 0333 366 0103. Caught before your engine runs, it is usually a drain and a thorough flush, done where the car is around Rossington. If you are reading before it has happened, the rest of this page is about why it occurs and how to make sure it does not.

AdBlue in a diesel vehicle: two tanks, two fillers

Diesel feeds the motor — yet many newer diesels driven round Rossington and Hayfield Green carry another liquid too. Stored in a tank of its own, AdBlue is fed into the exhaust stream and cleans it.

There is a filler for every tank. On a lot of vehicles the two sit side by side under the same flap; on others the AdBlue filler is in your boot or under the bonnet. The diesel side is topped up at the petrol pump all the time. Much less regularly, the AdBlue side is topped up — mostly from a bottle, by a person thinking about where it goes. The mistake grows in the gap between them.

Rossington: how AdBlue in your diesel tank happens

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

To start with, the warning. Low AdBlue triggers a warning from your car, and letting it run out leads to limp mode — hence a rushed top-up, perhaps before work off Sheep Bridge Lane, or at The Welfare and Social Club on the way home that evening.

The old car's cap is where the hand goes — but a hire car, a new car or a company car keeps the fillers somewhere else. That's the second factor: a strange motor.

And the bottle fits. A bottle with a spout goes into a diesel filler as easily as an AdBlue one, so nothing stops the tip after it has started. Whether it occurs in Littleworth or the middle of Rossington, it's the same few seconds.

Flushing a diesel fuel system after AdBlue, Rossington

Which filler is for AdBlue, and which for diesel?

Look at these first, on a forecourt in Rossington or a driveway over in Branton. A few seconds, that's all.

  • Check the cap rather than going by position: AdBlue caps are regularly blue or marked "AdBlue", and diesel caps usually aren't.
  • The size. On many vehicles the AdBlue filler neck is the smaller of the two.
  • The flap. Look inside your fuel flap for a label. Many cars say there which fuel goes where.
  • In your boot or under the bonnet: that is where your filler is if it's not by the diesel cap, and the handbook says which.
  • The person who drove the car last. On a hire or company car picked up from somewhere like the car park outside Doncaster, ask before you leave, not when the light comes on.

How to top up without AdBlue in the diesel tank

For the day the warning appears — wherever it is across South Yorkshire — a routine to follow.

  • Switch off after you park — level ground, engine stopped, and never rushed beside Greenlands Avenue on the verge.
  • Silly as it sounds, saying "AdBlue" aloud as you unscrew the cap works — once you have located your filler and read the cap.
  • Both behind a single flap? So make sure the lid on the diesel side is still shut before lifting the bottle.
  • Slowly is best, through the bottle's own spout, until it is full or the bottle is empty.
  • Close the cap and check once more. Make sure your diesel cap was never opened. Only then start the vehicle.

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

Already put AdBlue in your diesel tank in Rossington?

What follows is a short order of things, starting with not starting your engine. Do not switch the ignition on; on plenty of diesels that alone runs the fuel pump. AdBlue doesn't mix with diesel — it sinks to the bottom of that tank, where your fuel is pulled from — so do not top up with diesel to thin it.

The staff at Asda, Esso or another forecourt will usually help pushing your car away if asked. Leave it where it is if you're on your own drive in Rossington.

Stop as soon as it is safe then switch off, if your engine has already run. On the M18, under a mile from Rossington, that means the next junction. Tell us about how far it went: a run towards Doncaster, under 5 miles away, is a bigger job than a short hop across Rossington.

What takes place when our technicians get there in Rossington

Wherever the vehicle has stopped, be it by Rossington St Michael's CofE Primary School, beside St Michaels or on your own drive, our van comes to it. The answers determine this work and our quote, and so our technicians ask what went in, about how much, and if it's run. That quote is given over the phone, ahead of any van leaving.

The system is then cleaned thoroughly, once your tank is cleared. With AdBlue that counts more than with petrol: it crystallises and is corrosive to some of the metals in a fuel system, so it does not wash out on its own. The filter flushed or, if it must be, replaced; fresh diesel in; then a check of your vehicle. Before we leave, our engineers fire it up and make sure that it is running correctly.

Most jobs are done in about half an hour after we arrive, provided the engine 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. Many insurance policies include misfuelling cover, and so it is worth checking yours whilst we're on the way.

AdBlue drains across South Yorkshire, Rossington included

As a village, Rossington has the same vans as surrounding places — New Rossington, Bessacarr — all the way through DN postcodes and the wider area around them. Quote a postcode beginning DN11 0, and our van arrives fastest.

The car doesn't need to shift. We drain it where it is — a side street near Rossington Leisure Centre, a lay-by on the way to Gelster Lane Holt, a drive. Tricky to pin down, like the back of Brodsworth Way Pavilion? Close to a county line? Asking is better than guessing, so phone.

In short, for Rossington drivers

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