Usually, if your motor has not turned, it is drained and thoroughly purged where the vehicle sits in Bradley. Here in advance? Then what follows explains why it happens and what to stop it ever happening. ## AdBlue in a diesel vehicle, and its separate tank No single fluid but two: that is what many modern diesels near Bradley and Riddings run, with diesel feeding your motor. Your exhaust, not your motor, is where AdBlue ends up: sprayed into the fumes to fresh it, from a separate tank. There is a filler on every tank. Plenty of cars share a single flap for the two, whereas others move the AdBlue filler to your boot or under the bonnet. The diesel side is topped up at the pump all the time. The AdBlue side is topped up far less commonly, normally from a bottle, and usually by someone who has to stop and think where it goes. Mistakes happen in that gap between them. ## How does AdBlue in your diesel tank happen in Bradley? It is hardly ever carelessness. Three things tend to line up. The warning comes first. As AdBlue runs low the vehicle tells you, and if it runs out completely, the vehicle goes into limp mode. So the top-up is done in a hurry: on a drive off Sherwood Avenue before work, or in the car park at White Cross Inn on the way home. New-to-you cars come next, as well. Hire cars, new vehicles and company motors put their fillers differently, and the hand reaches for the cap used on the old one. A spouted bottle meets no obstacle at a diesel filler any more than at an AdBlue one. And so the tip, once started, carries on. Colne Bridge or the heart of Bradley: it is the same few seconds in both. ## Telling the AdBlue filler from the diesel filler Whether a Bradley forecourt or a driveway over in Bracken Hill, take a couple of seconds on these before any is poured in. - Position misleads; the cap does not. AdBlue ones tend to be blue or bear the name "AdBlue" — diesel caps normally don't. - The size. On many motors the AdBlue filler neck is the smaller of the two. - Check inside the fuel flap: many cars have a label there saying which fuel goes where. - The handbook. If the filler isn't by the diesel cap, it is in the boot or under the bonnet, and the handbook says which. - The person who drove the vehicle last. On a hire or company car picked up from somewhere like the car park outside Deighton, ask before you leave, not when the light comes on. ## Topping up AdBlue without it reaching the diesel tank A routine for the day the light comes on, wherever around West Yorkshire that is. - Switch off once parked — flat ground, motor stopped, and not rushed beside Elder Road on the verge. - Say "AdBlue" out loud as you unscrew the cap, once finding the AdBlue filler and read it. Daft, perhaps, but it does the trick. - The two under a single flap? Then confirm the cap on the diesel side stays closed before raising the bottle. - Finish when the tank fills or the bottle is empty; before that, tip gently through its built-in spout. - Close the cap and check again. Make sure the diesel cap was never opened. Only then start your car. If at step two or three you find you have already poured into your diesel side, stop there. Don't go on to step five. ## Put AdBlue in your diesel tank in Bradley already? Don't start the motor: that is how the short order of things begins. Do not switch the ignition on; on many diesels that alone runs the fuel pump. Do not top up with diesel to thin it: AdBlue doesn't mix with diesel, it sinks to the bottom of your tank, where the fuel is drawn from. Ask the staff to help push the vehicle clear of the pump if you are at a forecourt — the Esso, the another forecourt nearby or somewhere else. If you are on your own driveway in Bradley, leave the car where it stands. Already run? Pull over once it is safe, then turn off. On the M62, under a mile from Bradley, that means the next exit. Tell us roughly how far it went: a run towards Bradford, under 10 miles away, is a bigger job than a short hop across Bradley. ## What occurs when our engineers get there in Bradley By St Thomas CE Primary School, close to St Thomas' Church or on your own driveway: wherever the vehicle has stopped, our engineers come to it. Both the work and our price rest on three answers — what fluid, what quantity, and whether it's run — so our technicians ask. That quote is given on the call, ahead of any van leaving. The fuel system is then purged thoroughly, once the tank is cleared. With AdBlue that counts more than with petrol: it crystallises and is corrosive to some of the metals in a fuel system, so it does not wash out on its own. A test is last: before that, clean diesel is added, and the fuel filter is cleaned or changed if necessary. We don't leave until it has been fired up and is running smoothly. Most jobs are finished in about half an hour once we get there, as long as your motor hasn't run — and the pumps our engineers use are safe on a busy forecourt yet quiet after dark outside a house. The insurer will ask for an engineer's report and the VAT invoice, and you get both once this job is done. Payment is on the day, with no deposit. Many insurance policies include misfuelling cover, so it's worth checking yours while we're on the way. ## About Bradley, for a moment Bradley is a suburban area in West Yorkshire, situated on the riverside at an elevation of 83 metres, with semi-detached housing being the predominant type of accommodation.
