Then set this page aside for now, leave the ignition and motor off, and ring 0333 366 0103. In Little Leven, finding it before the engine turns normally leaves draining and a thorough flush where it stands. Reading in advance? Then the rest explains why it happens and how to prevent it ever happening. ## Why does AdBlue in a diesel vehicle need its own filler? Many modern diesels around Brandesburton, as well as Little Leven, carry on two fluids; the motor takes only the diesel. The exhaust, not the motor, is where AdBlue ends up: dosed into the fumes to fresh it, from its own tank. Every tank has a filler of its own. Some vehicles keep the AdBlue filler in your boot or under the bonnet; a lot of others place the two side by side under one flap. Filling the diesel side at the petrol pump goes on all the time. Rarely topped up, AdBlue usually goes in from a bottle, poured by a driver who has to stop and think what cap it needs. That gap is where the error lives. ## AdBlue in the diesel tank in Little Leven: how it takes place Three things tend to line up, and carelessness is rarely one of them. On a drive off Westlands Way before work, or in the car park outside The New Inn on the way home: that is where the rushed top-up happens. What is the reason for the rush? As AdBlue runs low your car warns you, and once it is gone, limp mode kicks in. The old car's cap is where your hand reaches — but a hire car, a new car or a company car puts the fillers somewhere else. That is a second factor: a new motor. Lastly, the spout fits: diesel filler or AdBlue one, it slides in just as readily, and after the pour starts, no part stops it. Leven or the middle of Little Leven: it is the same few seconds either way. ## Which filler is for AdBlue, and which for diesel? Check these before pouring, at a forecourt around Little Leven or a drive over in Sandfield. A few seconds, no more. - Blue and marking: an AdBlue cap is often blue, or says "AdBlue", where a diesel cap usually doesn't. Go by the cap, not where it sits. - Check the size: the smaller filler neck is, on plenty of cars, the AdBlue one. - Check inside the fuel flap: many motors carry a label there saying which fuel goes where. - In the boot or under the bonnet: that is where your filler is if it's not by the diesel cap, and the handbook tells you which. - Collecting a hire or company car, say at the car park at Arram? Ask whoever drove the car last before leaving, rather than when the light goes on. ## Keeping AdBlue out of your diesel tank when you top up A routine for the day the light comes on, wherever across East Riding of Yorkshire that is. - Pull in on level, motor off, with time to spare — never hurried on the side of North Street. - Locate the AdBlue filler, check the cap, and speak the name "AdBlue" out loud as you unscrew it. It seems daft. It works. - Both under a single flap? Then confirm the lid on your diesel side stays shut ahead of lifting the bottle. - Stop when that tank fills or the bottle is empty; until then, tip gently through the built-in spout. - Shut the cap, then check once more — confirm the diesel filler remained shut throughout. Only then, start the car. Stop there if you find, at step two or three, that you have already poured into the diesel side. Stage five is off limits. ## AdBlue in the diesel tank already, around Little Leven? Do not start your engine: that's where the short order of things starts. On many diesels your ignition alone runs the fuel pump, and so don't switch the car on. Diluting it with more diesel won't work, since AdBlue settles to the bottom rather than blending — and that is where the fuel is pulled from. If you're at a forecourt, whether it's the Gulf or the Rix, ask the staff to help roll the vehicle clear of the petrol pump. Leave it where it is if you're on your own driveway in Little Leven. If your engine has already run, stop as soon as it is safe and switch off. The next exit means where to leave when you are on the M62, under 25 miles from Little Leven. About how far did it go?

Those replies determine this work and our quote, and so our engineers ask what went in, roughly how much, and if it has run. Nobody heads out until you've heard the price over the phone. Your system is then cleaned thoroughly, after that tank is emptied. More than with petrol, it counts here: the crystals form, certain metals are attacked, and nothing clears away on its own, no matter how long it sits. The filter flushed or, where it must be, swapped; clean diesel in; then a test of your car. Before we leave, our engineers fire it up and check that it's running properly. If your engine hasn't run, most jobs take about half an hour once we are there, using pumps that are fine on a busy forecourt and quiet enough to use outside a house at night. No money upfront; you settle up that day. At the end, a VAT invoice and the report from the engineer are handed to you for your insurer. Before we get there, have a look at your insurance documents; plenty carry cover for misfuelling. ## About Little Leven itself Little Leven is a locality situated on the riverside in the East Riding of Yorkshire, with a population of around 1298 people.
