In that case put this page down a moment, leave your ignition and engine off, and phone 0333 366 0103. A drain and a thorough flush, carried out right where the vehicle stands in Dogridge, is usually what it takes if caught before your motor runs. Reading in advance? Then the rest covers why it comes about and what to stop it happening at all. ## Why does AdBlue in a diesel vehicle need its own filler? Diesel feeds the engine — yet many modern diesels seen round Dogridge and Purton carry a second fluid as well. 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 one filler of its own. On a lot of vehicles the two sit side by side under the same flap; on others the AdBlue filler is in your boot or under the bonnet. Filling the diesel side at the petrol pump goes on constantly. Much less commonly, the AdBlue side is filled — normally from a bottle, by someone thinking about where it goes. Mistakes happen in that gap between the two. ## How AdBlue in the diesel tank takes place in Dogridge 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 goes into limp mode. So the top-up is done in a hurry: on a drive off Restrop View before work, or in the car park outside The Royal George on the way home. Unfamiliar vehicles come second, as well. Hire cars, new vehicles and company motors put their fillers differently, and the hand goes for the cap used on the old one. Nothing stops the pour after it has started, because a bottle with a spout goes into a diesel filler as easily as an AdBlue one. The bottle fits. It's a few seconds, whether out in Restrop or right in the centre of Dogridge. ## The AdBlue filler and your diesel filler: telling them apart Look at these before pouring, on a forecourt around Dogridge or a drive over in Church End. Seconds, no more. - The cap. The AdBlue cap is regularly blue, or marked "AdBlue". Your diesel cap usually is not. Read it rather than going by position. - Check the size: the smaller neck is, on plenty of cars, the AdBlue one. - A label inside the fuel flap frequently shows which fuel goes where, on plenty of cars. Check for it. - In the boot or under the bonnet: that is where the filler sits if it is not by your diesel cap, and the handbook tells you which. - The person who drove it last. On a hire or company car picked up from somewhere like the car park outside Swindon, ask before you leave, not when the light comes on. ## Keeping AdBlue out of your diesel tank when you top up On the day the warning comes on — anywhere it is in Wiltshire — a simple routine to use. - Turn off once parked — flat ground, motor stopped, and not rushed beside Dogridge on the verge. - Find the AdBlue filler and read the cap. Say "AdBlue" out loud as you unscrew it. It sounds daft and it does the trick. - The diesel cap stays on. When the two share a flap, make sure it is closed before the bottle comes up. - Using the bottle's own spout, pour slowly — and stop when it's full or the bottle is empty. - Shut the cap, and look again — confirm your diesel filler remained shut the whole time. After that, start the vehicle. Discover during the second or third step that AdBlue went in the diesel filler? That is where you stop. Step five stays off limits. ## AdBlue in your diesel tank already, around Dogridge? Then the order of things is short. Don't start the motor. The fuel pump starts on many diesels the moment the ignition goes on — and so leave it off. Thinning it with extra diesel won't work, since AdBlue sinks to the base instead of mixing — and that's where your fuel is pulled from. The staff at Esso, BP or any forecourt will usually lend a hand to push the vehicle away when you ask. Your own driveway in Dogridge is the place it stays. If the motor has already run, stop as soon as it is safe then switch off. Dogridge lies under 3 miles from the M4; there, take the next exit. Mileage counts — a quick hop across Dogridge makes a smaller job than driving under 25 miles to Gloucester — so say roughly how far it went. ## Dogridge: what happens when we get there Wherever your car came to rest, be it outside St Mary's Church of England Primary School & Nursery, Purton, beside Old Scout Hut or on your own drive, the van travels to it. Which fluid got in, the quantity, and whether it ran: our technicians ask because those replies set the work and price. You hear that price by phone, before anybody sets off. After that: draining, then a thorough flush of the entire system. Unlike petrol, AdBlue forms crystals and eats at certain fuel-system metals, and none of that washes out unaided. Hence it matters more. A test is last: before that, clean diesel goes in, and the filter is cleaned or changed if necessary. The engine is fired up next and checked to be sure it runs smoothly, all before we go. With pumps safe on a working forecourt and quiet enough for use outside a house at night, most jobs where your engine hasn't run need about half an hour after we arrive. The insurer will ask for an engineer's report and the VAT invoice, and you get both at the end. Payment comes on the day, with no deposit. Misfuelling cover is included in many insurance policies — and so use the wait to check yours. ## About Dogridge and where it is Dogridge is a suburban area in Wiltshire, situated inland at an elevation of 141 metres, with semi-detached housing being the predominant type of accommodation.
