In that case put this page aside for now, keep your ignition and engine off, and phone 0333 366 0103. In Worksop, finding it before the engine turns usually leaves draining and a thorough flush on the spot. If you are reading before it has happened, the remainder of this page is about why it occurs and how to make sure it doesn't. ## Why does AdBlue in a diesel car need its own filler? Diesel goes to your motor — yet plenty of modern diesels driven round Worksop and Sunnyside hold a second fluid too. Stored in a tank of its own, AdBlue is fed into your exhaust gas to clean it. Separate tanks, different fillers. Under one flap, side by side: that is the arrangement on many cars. On others, AdBlue's filler sits under the bonnet or in the boot instead. Filling the diesel side at the pump happens constantly. Seldom filled, AdBlue normally comes from a bottle, poured by someone who must stop and think which cap to use. The mistake lives in that gap. ## How does AdBlue in your diesel tank take place around Worksop? It is seldom carelessness. Three things tend to line up. On a drive off Bridge Place before work, or in the car park at Lockside heading home: that is where the rushed top-up takes place. What is the reason for the rush? As AdBlue runs low your car warns you, and if it's empty, limp mode follows. The old car's filler is where your hand reaches — but a hire car, a new car or a company car keeps the fillers somewhere else. That is a second thing: an unfamiliar car. Third, the spout goes in: a diesel filler or AdBlue filler, it goes in just as readily, and after the tip starts, nothing stops it. It takes seconds, be it in Bracebridge or right in the heart of Worksop. ## The AdBlue filler and your diesel filler: telling them apart A couple of seconds is all the checks take — so run through them before you tip anything, on a drive in Woodhouse or a forecourt around Worksop. - The cap. The AdBlue cap is regularly blue, or marked "AdBlue". The diesel cap normally isn't. Read it instead of going by where it sits. - On many motors, size gives it away: AdBlue gets the smaller filler neck. - A label inside your fuel flap frequently shows which fuel goes where, on plenty of motors. Look for it. - In the boot or under the bonnet: that's where your filler sits if it is not by your diesel cap, and the handbook says which. - The previous driver will know. Ask as you pick up a rental or fleet car — at the nearest station's car park, perhaps — not when the warning appears. ## How to top up without AdBlue in your diesel tank On the day the light appears — wherever it is in Nottinghamshire — a routine to follow. - Pull in somewhere level, engine off, with time to spare — never rushing on the side of Dock Road. - Find the AdBlue filler, check the cap, and speak the word "AdBlue" aloud as you unscrew it. It sounds daft. It works. - The diesel cap remains on. Where both share a flap, make sure it's closed before lifting the bottle. - Using the bottle's own spout, pour slowly — and stop when it is full or the bottle is empty. - Before you start the car, close the cap and check a second time that your diesel cap never came off. If at step two or three you find you have already poured into your diesel side, stop there. Leave out step five entirely. ## Already put AdBlue in your diesel tank around Worksop? Don't start the motor: that's where the short order of things starts. Do not switch the ignition on; on many diesels that alone runs the fuel pump. AdBlue doesn't mix with diesel — it sinks to the bottom of the tank, where the fuel is pulled from — so do not top up with diesel to thin it. The attendants at Gateford Service Station, Morrisons or another forecourt will normally lend a hand pushing the car clear if asked. Your own drive in Worksop is the place it stays. Already started? Pull over once it is sensible, then turn off. On the Doncaster By-Pass, under 10 miles from Worksop, that means the next exit. Tell us roughly how far it went: a run towards Doncaster, under 15 miles away, is a bigger job than a short hop across Worksop. ## When our engineers arrive around Worksop, what happens? Anywhere your car came to rest, whether by Redlands Primary and Nursery School, beside Poplars Church or on your own drive, our van comes to it. What fluid got in, the quantity, and if it ran: our engineers ask since the replies decide the work and quote. You get that quote by phone, before anyone heads out. Next: a drain, then a thorough flush of the entire system. Much more than with petrol, it counts with AdBlue: crystals build up, some metals corrode, and nothing clears away unaided, no matter how long it is left. Your filter is flushed, or replaced where it needs to be; fresh diesel goes in; and your car is tested. Next we fire it up and confirm it runs properly before we go. Most jobs are finished in about half an hour after we get there, provided your engine hasn't run — and the pumps our technicians use are safe on a live forecourt and quiet after dark beside a house. Your insurer will ask for an engineer's report and the VAT invoice, and you get both once this job is done. Payment comes on the day, with no deposit. It is worth checking your policy as the van travels to you: misfuelling cover comes with many policies. ## About Worksop itself Worksop is a town in Nottinghamshire, situated on the River Ryton in the East Midlands region of England.
