Caught before the motor runs, it's usually a drain and a thorough flush, done where the vehicle is around Hessle Cliff. If you're reading before it has happened, the remainder of this page is about why it takes place and how to make sure it does not. ## Two fillers, two tanks: AdBlue in a diesel vehicle Plenty of newer diesels in Northfield, as well as Hessle Cliff, run on two liquids; your engine takes only your diesel. Its own tank keeps it, and from there it goes to the exhaust, and there a spray treats the fumes. Each tank has its own filler. Under one flap, side by side: that's the arrangement on a lot of cars. On others, AdBlue's filler is beneath the bonnet or in the boot instead. The diesel side is filled at the petrol pump all the time. Seldom filled, AdBlue normally comes out of a bottle, tipped by someone who has to stop and think what cap to use. The mistake grows in that gap between them. ## How AdBlue in the diesel tank happens around Hessle Cliff Three things tend to come together, and carelessness is seldom one of them. 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 Cliff Road before work, or in the car park outside The Country Park Inn on the way home. Then your car is new. A hire car, a new motor or a company car puts the fillers where your last one did not, and your hand reaches for the cap it would have used on the old one. And the bottle fits. A bottle with a spout goes into a diesel filler as easily as an AdBlue one, and so nothing stops the tip once it has started. Whether it happens in West Hill or the middle of Hessle Cliff, it's the same few seconds. ## The AdBlue filler and the diesel filler: telling them apart Look at these first, at a forecourt around Hessle Cliff or a driveway over in Barton Waterside. A few seconds, no more. - Position can mislead; the cap does not. AdBlue caps tend to be blue or bear the word "AdBlue" — diesel caps usually do not. - The size. On plenty of motors 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 sits if it is not by your diesel cap, and the handbook says which. - Ask the person who drove it last — before you leave, not when the light comes on — if you collect a hire or company car from somewhere like the car park outside Hessle. ## How to top up without AdBlue in your diesel tank On the day the light appears — wherever you are around East Riding of Yorkshire — a routine to use. - Switch off once parked — flat ground, engine stopped, and never rushed by The Coachings on the verge. - Find the AdBlue filler and read the cap. Say "AdBlue" out loud as you unscrew it. It sounds silly and it works. - Leave your diesel cap on. If both sit under one flap, check your diesel cap is still closed before you lift the bottle. - Using the bottle's own spout, pour slowly — and stop when it is full or the bottle is empty. - Shut the cap, and look once more — confirm the diesel filler stayed shut throughout. After that, start the vehicle. Stop there if you find, at stage two or three, that you've already poured into your diesel side. Leave out stage five altogether. ## Put AdBlue in the diesel tank in Hessle Cliff already? Then the order of things is short. Don't start your motor. On plenty of diesels the ignition alone runs the fuel pump, so do not switch the vehicle on. AdBlue does not mix with diesel — it sinks to the bottom of that tank, where the fuel is pulled from — so do not top up with diesel to dilute it. At a forecourt — Esso, Sainsbury's or any other — the staff will normally help roll the vehicle away, when you ask. At home around Hessle Cliff? Then the vehicle remains where it is. Stop as soon as it is safe and switch off, if the motor has already run. Come off the M180 — under 10 miles out of Hessle Cliff — at the first junction. Roughly how far did it go? Crossing Hessle Cliff is less a job than a run of under 10 miles towards Kingston upon Hull, and so tell us. ## Hessle Cliff: what takes place when our engineers turn up The van comes to the vehicle wherever it has come to rest — your own drive, near Start of Wolds Way, or outside All Saints Church of England Infant Academy. What liquid got in, the amount, and if it ran: our technicians ask because those replies set both work and quote. During the phone call itself, you hear the price — ahead of dispatch. Next: a drain, then a thorough flush of the entire system. Not like petrol, AdBlue forms crystals and eats at some fuel-system metals, and none of that washes out unaided. That is why it matters more. Once the fuel filter has been cleaned — or renewed, where required — fresh diesel is added, and finally the vehicle gets tested. Your engine is fired up next and checked to confirm it runs properly, all before our technicians go. If your motor hasn't run, most jobs take about half an hour once we are there, using pumps that are safe on a busy forecourt and quiet enough to use outside a house at night. You pay on the day, with nothing upfront, and get a VAT invoice and an engineer report for your insurer. It is worth looking at your insurance while we travel to you: misfuelling cover is included with many policies. ## About Hessle Cliff and where it is Hessle Cliff is a suburban area located on the outskirts of Kingston upon Hull, situated near the Humber Estuary in East Riding of Yorkshire.
