Caught before your engine runs, it is normally a drain and a thorough flush, done where the vehicle is around Daw Green. The rest of this page covers why it takes place and how to make sure it doesn't — handy if you are reading before it has happened. ## AdBlue in a diesel motor: two tanks, two fillers Plenty of newer diesels on the roads about Daw Green and Westborough carry two liquids, not one. Diesel goes to the motor. AdBlue goes to the exhaust, where it is sprayed into the gas to clean it, and it lives in a tank of its own. Separate tanks, separate fillers. Under one flap, next to each other: that's the layout on many cars. Elsewhere, AdBlue's filler is beneath the bonnet or in the boot instead. At the pump, your diesel side is topped up constantly. Far less frequently, the AdBlue side is filled — mostly from a bottle, by a person working out where it goes. That gap is where the mistake lives. ## How AdBlue in your diesel tank happens around Daw Green Three things tend to come together, and carelessness is rarely one of them. On a drive off St John Parade before work, or in the car park outside Park Hotel heading home: that's where the hurried top-up happens. What is the reason for the rush? As AdBlue gets low the vehicle warns you, and if it is empty, limp mode kicks in. The old car's cap is where your hand goes — but a hire car, a new motor or a company car keeps the fillers elsewhere. That is the second thing: a strange motor. A spout-topped bottle meets no resistance at a diesel filler no more than at an AdBlue one. And so the pour, after begun, carries on. The same few seconds decide it, in the middle of Daw Green or out in West Town. ## How to tell the AdBlue filler from the diesel one Before you pour anything, whether on a drive in Dewsbury Moor or a forecourt in Daw Green, check these. They take a few seconds. - Colour and marking: an AdBlue cap is frequently blue, or says "AdBlue", where a diesel cap usually does not. Go by the cap, not where it sits. - On many cars, size tells: AdBlue gets the smaller filler neck. - Open the filler flap and check for a label — plenty of cars show what belongs in each filler right there. - In the boot or under the bonnet: that's where the filler sits if it's not by your diesel cap, and the handbook says which. - Check with the person who drove it last — before you leave, not when the light comes on — when you collect a hire or company car from somewhere like the car park outside Dewsbury. ## Topping up AdBlue without it reaching the diesel tank On the day the light comes on — wherever you are in West Yorkshire — a simple routine to follow. - Pull in on level, engine off, with time in hand — never rushing on the side of Middle Road. - Silly as it sounds, speaking "AdBlue" aloud while you unscrew the cap works — once you've found the filler and read it. - The diesel cap stays on. Where the two share a flap, make sure it's shut before the bottle comes up. - Using the bottle's own spout, tip slowly — and stop when it is full or the bottle is empty. - Shut the cap, and look again — confirm the diesel filler stayed closed throughout. After that, start the car. Find at stage two or three that it has already gone into the diesel side? Then stop right there. Do not go on to step five. ## Put AdBlue in the diesel tank in Daw Green already? Then the order of things is short. Don't start the motor. On plenty of diesels your ignition alone runs the fuel pump, and so do not switch it on. Don't top up with diesel to dilute it: AdBlue does not mix with diesel, it sinks to the bottom of the tank, where your fuel is pulled from. If you're on a forecourt, whether it's the Asda or the Shell, ask the attendants to help push the vehicle away from the petrol pump. On your own drive in Daw Green? So your car remains put. If the engine has already run, stop as soon as it is safe then switch off. On the M62, under 5 miles from Daw Green, that means the next junction. A short hop across Daw Green is a smaller job than a run towards Wakefield, under 10 miles away, so tell us roughly how far it went. ## What occurs when we turn up in Daw Green Outside Boothroyd Primary Academy, close to St Matthew or on your own drive: wherever the car has stopped, our technicians come to it. Both the work and our quote rest on three answers — what fluid, which amount, and if it's run — so our technicians ask. On the call itself, you hear the price — ahead of dispatch. Draining that tank comes next, followed by a full flush of the fuel system. AdBlue crystallises and is corrosive to some of the metals in a fuel system, so it doesn't wash out on its own — which is why that counts more with AdBlue than with petrol. The filter is flushed, or replaced where it needs to be; clean diesel goes in; and the vehicle is tested. The motor is fired up next and tested to be sure it runs properly, all before our engineers leave. Most jobs are finished in about half an hour once our engineers arrive, provided your motor hasn't run — and the pumps our engineers use are safe on a live forecourt yet quiet at night outside a house. Paying is on the day, not upfront, and you receive the documents an insurer asks for: an engineer's report and a VAT invoice. Before we get there, take a look at your policy; many carry cover for misfuelling. ## About Daw Green Daw Green is a suburban area in West Yorkshire, situated on the riverside at an elevation of around 80 metres.
