Why It Occurs and How to Prevent It: AdBlue in a Diesel Tank in Monk Bretton

Caught before your engine runs, it is normally a drain and a thorough flush, done where the car is around Monk Bretton. Not happened yet?

AdBlue in a diesel motor: two tanks, two fillers

Diesel goes to the motor — yet many current diesels seen about Monk Bretton and Athersley South carry a second liquid too. AdBlue goes to the exhaust, where it is sprayed into the gas to fresh it, and it lives in a tank of its own.

Each tank has a filler of its own. Under one flap, side by side: that's the arrangement on a lot of motors. On others, AdBlue's filler is under the bonnet or in the boot instead. At the pump, your diesel side gets filled constantly. The AdBlue side is filled far less commonly, normally from a bottle, and normally by someone who has to stop and think where it goes. The mistake lives in that gap.

How does AdBlue in the diesel tank occur in Monk Bretton?

Seldom is it carelessness: usually three things coincide.

The warning comes first. As AdBlue runs low your car tells you, and if it runs out completely, your vehicle drops into limp mode. So the top-up is done in a hurry: on a drive off Judy Row before work, or in the car park at The Pheasant on the way home.

Then the vehicle is unfamiliar. A hire car, a new motor or a company car puts the fillers where your last one didn't, and your hand hits for the cap it would have used on the old one.

A spout-topped bottle finds no obstacle at a diesel filler no more than at an AdBlue one. And so the tip, after started, keeps on. Smithies or the middle of Monk Bretton: it takes the same few seconds either way.

How to tell the AdBlue filler from the diesel one

A few seconds is all the checks take — so run through them before you pour anything, on a drive in West Green or a forecourt around Monk Bretton.

  • Check the cap instead of going by where it sits: AdBlue caps are regularly blue or marked "AdBlue", and diesel caps usually are not.
  • On many vehicles, size gives it away: AdBlue has the smaller filler neck.
  • Lift the filler flap and look for a label — many cars show which belongs in which filler just there.
  • Cannot find it next to the diesel filler? Then check beneath the bonnet or in your boot — the handbook will say which.
  • The person who drove the vehicle last. On a hire or company car picked up from somewhere like the car park at Barnsley, ask before you leave, not when the light comes on.

How to top up without AdBlue in the diesel tank

For the day the light comes on — wherever you are around South Yorkshire — a routine to use.

  • Not in a rush on the side of Hunt Close, not on a slope, not with the motor running: park then switch off properly.
  • Find the AdBlue filler and read the cap. Say "AdBlue" out loud as you unscrew it. It sounds silly and it works.
  • Both under one flap? Then confirm the lid on your diesel side is still closed before lifting the bottle.
  • Slowly is best, through the bottle's own spout, until it's full or the bottle is empty.
  • Close the cap and check once more. Make sure the diesel cap was never opened. Only then start your car.

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

Already put AdBlue in the diesel tank in Monk Bretton?

Short order, then. Top of it: the motor remains off. On plenty of diesels the ignition alone runs the fuel pump, and so don't switch the car on. AdBlue doesn't mix with diesel — it sinks to the bottom of the tank, where your fuel is pulled from — so do not top up with diesel to thin it.

At a forecourt — JET, Asda or another — the attendants will normally help roll your car clear, if you ask. At home around Monk Bretton? So your car remains put.

When your motor has run already, stop somewhere safe then turn the vehicle off. Come off the M1 — under 3 miles out of Monk Bretton — at the first junction. Mileage counts — a short hop across Monk Bretton makes a smaller job than driving under 10 miles to Wakefield — so say about how far it went.

When our technicians get there in Monk Bretton, what occurs?

The van reaches the vehicle wherever it stopped — your own drive, beside WWI & WWII Memorial, or by Lift St Helen's. What fluid was put in, the quantity, and if it ran: our technicians ask because the replies set both work and price. Nobody heads out until you've heard the price by phone.

Emptying your tank comes next, followed by a full flush of your system. With AdBlue that matters more than with petrol: it crystallises and is corrosive to some of the metals in a fuel system, so it doesn't wash out on its own. After your filter has been cleaned — or replaced, where required — clean diesel goes in, and then your car is tested. The motor is fired up next and tested to make sure it runs smoothly, all before our technicians leave.

If the motor has not run, most jobs take about half an hour once we're there, using pumps that are fine on a busy forecourt and quiet enough to use outside a house after dark. No money in advance; you settle up on the day. Afterwards, a VAT invoice and the report from the engineer go to you for your insurer. Many insurance policies include misfuelling cover, so it is worth checking yours whilst we're on the way.
