In that case set this page down for now, leave your ignition and engine off, then ring 0333 366 0103. In Brackenhill, catching it before your motor turns usually leaves a drain and a full flush where it stands. Here in advance? Then the rest covers why it comes about and what to prevent it happening at all. ## AdBlue in a diesel car: two tanks, two fillers Diesel goes to the motor — yet many modern diesels seen around Brackenhill and Hessle carry a second liquid too. Your exhaust, not the motor, is where AdBlue ends up: dosed into the fumes to clean it, from a separate tank. Separate tanks, different fillers. Plenty of vehicles have a single flap for both, while some move the AdBlue filler to the boot or under the bonnet. The diesel side is topped up at the petrol pump all the time. Much less frequently, the AdBlue side is topped up — normally from a bottle, by someone thinking about where it goes. It's in the gap that the mistake lives. ## How AdBlue in your diesel tank happens in Brackenhill It's rarely carelessness. Three things tend to line up. On a drive off Paddock Close before work, or in the car park at The Angel heading home: that's where the rushed top-up takes place. What is the reason for the rush? As AdBlue gets low the vehicle tells you, and once it's gone, limp mode follows. The old car's cap is where your hand reaches — but a rental car, a new motor or a company car puts the fillers somewhere else. That is a second thing: a strange vehicle. A spouted bottle meets no resistance at a diesel filler any more than at an AdBlue one. So the pour, after started, keeps on. It's seconds, be it in Ackworth Moor Top or bang in the heart of Brackenhill. ## How to tell the AdBlue filler from the diesel one Before you pour anything, whether on a driveway in Charlestown Estate or a forecourt in Brackenhill, check these. They take a couple of seconds. - The cap. The AdBlue cap is often blue, or marked "AdBlue". The diesel cap usually isn't. Read it instead of going by where it sits. - The size. On plenty of vehicles the AdBlue filler neck is the smaller of the two. - The flap. Look inside the fuel flap for a label. Many vehicles say there which fuel goes where. - Cannot find it next to your diesel filler? Then look below the bonnet or inside your boot — the owner's manual says which. - Check with the person who drove it last — before you leave, not when the light comes on — if you pick up a hire or company car from somewhere like the car park at Fitzwilliam. ## Topping up AdBlue without it reaching your diesel tank For the day the warning comes on — anywhere you are across West Yorkshire — a routine to use. - Not in a rush on the side of Barnsdale Way, not on a slope, not with your engine running: park then switch off first. - Locate the AdBlue filler, check the cap, and say the name "AdBlue" out loud while unscrewing it. It sounds silly. It does the trick. - The diesel cap remains on. When the two sit under a flap, make sure it's closed before the bottle comes up. - Stop once that tank is topped up or the bottle is empty; until then, pour slowly through the own spout. - Close the cap and check again. Make sure the diesel cap was never opened. Only then start the vehicle. Find at stage two or three that it's already gone into your diesel side? Then stop right there. Step five stays out. ## Brackenhill: already put AdBlue in the diesel tank? Short list, then. First: the engine stays off. On plenty of diesels your ignition alone runs the fuel pump, and so don't switch the car on. Topping up with diesel won't thin it: rather than mixing, AdBlue sinks to the base of your tank, right where fuel is taken from. At a forecourt — Esso, BP or any other — the attendants will normally help roll the vehicle away, when you ask. At home around Brackenhill? So the vehicle remains put. When the motor has been run already, stop somewhere safe then turn it off. Come off the M62 — under 5 miles out of Brackenhill — at the first exit. Tell us roughly how far it went: a run towards Wakefield, under 10 miles away, is a bigger job than a short hop across Brackenhill. ## What occurs when we arrive around Brackenhill We come to your car wherever it has stopped, whether that's outside Outwood Primary Academy Bell Lane, near Ackworth Parish Council Community Centre or on your own driveway. Both the work and our price depend on three replies — what liquid, what amount, and if it's run — so we ask. You get that price on the phone, before anybody sets off. Emptying the tank comes next, followed by a full flush of the fuel system. Much more than with petrol, it matters with AdBlue: the crystals form, some metals are attacked, and nothing washes away unaided, however long it is left. A test comes at the end: before that, fresh diesel goes in, and the fuel filter is flushed or changed as needed. Your engine is started next and tested to be sure it runs properly, all before we leave. Unstarted cars mostly mean a half-hour visit from arrival. The equipment is fine on a busy forecourt, and hushed enough for a residential street late at night. You pay on the day, with nothing upfront, and get a VAT invoice and an engineer report for your insurer. Many insurance policies include misfuelling cover, and so it's worth checking yours while we are on the way. ## About Brackenhill and where it is Brackenhill is a suburban area situated on the riverside in West Yorkshire, with an elevation of 56 metres above sea level.
