Then set this page aside a moment, leave your ignition and engine off, and phone 0333 366 0103. Around Bridge End, finding it before your engine runs usually leaves a drain and a thorough flush on the spot. Here before the event? In that case what follows covers how it happens and what to stop it ever happening. ## Why does AdBlue in a diesel vehicle need its own filler? Plenty of newer diesels around Hope, as well as Bridge End, carry on two liquids; your engine takes just the diesel. AdBlue's own tank keeps it, and from there it goes to the exhaust, and there a spray treats the fumes. Separate tanks, separate fillers. Many of vehicles have a single flap for both, whereas some put the AdBlue filler to the boot or under the bonnet. At the pump, your diesel side gets filled constantly. A driver who has to stop and work out where it goes normally tops up the AdBlue side, from a bottle, and much less commonly. It is in that gap that the slip lives. ## AdBlue in the diesel tank in Bridge End: how it takes place Seldom is it carelessness: normally three things line up. The warning comes first. As AdBlue runs low your car 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 Rhyddyn Hill before work, or in the car park outside Ye Olde Castle Inn on the way home. The old car's filler is where the hand reaches — yet a rental car, a new vehicle or a company car keeps the fillers elsewhere. That's the second factor: an unfamiliar car. Lastly, the spout fits: diesel filler or AdBlue filler, it goes in as easily, and once the pour starts, no part stops it. The same few seconds settle it, in the middle of Bridge End or out in Caergwrle. ## Telling the AdBlue filler from your diesel filler Check these before pouring, at a forecourt in Bridge End or a driveway over in Cefn-y-bedd. Seconds, that's all. - The cap. The AdBlue cap is frequently blue, or marked "AdBlue". Your diesel cap usually is not. Read it instead of going by where it sits. - The size. On many motors the AdBlue filler neck is the smaller of the two. - A label inside the fuel flap often shows which fuel goes where, on many motors. Look for it. - Cannot find it next to your diesel filler? Then check beneath the bonnet or in your boot — the owner's manual will say where. - The person who drove the vehicle last. On a hire or company car picked up from somewhere like the car park at Caergwrle, ask before you leave, not when the light comes on. ## Keeping AdBlue out of your diesel tank when you top up A routine for the day the light comes on, wherever around Flintshire that is. - Turn off after you park — level ground, engine off, and not in a rush by Sunhill Drive at the roadside. - Say "AdBlue" out loud as you unscrew the cap, after you find the AdBlue filler and reading it. Daft, perhaps, yet it works. - If both sit under one flap, check your diesel cap is still closed before you lift the bottle — then leave it on. - Gently does it, through the bottle's own spout, till it's full or the bottle runs out. - Close the cap, and look again — making sure your diesel filler stayed closed the whole time. After that, start the vehicle. Spot at stage two or three that it has already gone into your diesel side? Then stop just there. Leave out step five entirely. ## Already put AdBlue in your diesel tank in Bridge End? Short order, then. Top of it: your engine stays unstarted. The fuel pump starts on many diesels the moment the ignition is switched on — and so keep it off. Diluting it with extra diesel won't work, because AdBlue sinks to the bottom rather than blending — and that is where the fuel is drawn from. Ask the attendants to help roll the car away from the pump if you're at a forecourt — the Gulf, the Shell or anywhere else. If you are on your own driveway in Bridge End, leave the car where it stands. Stop as soon as it is safe then switch off, if the motor has already run. Leave the M56 — under 15 miles out of Bridge End — at the next exit. Distance counts — a short hop across Bridge End is a smaller job than heading under 5 miles towards Wrexham — so say about how far it went. ## Our arrival in Bridge End, and what occurs next Anywhere the car has stopped, whether outside Dodleston CofE Primary School, near Caergwrle Castle or at home, the van travels to it. Which liquid was put in, the amount, and if it ran: our engineers ask since the replies decide the work and price. During the call itself, you hear the price — before dispatch. Emptying your tank comes next, then a thorough flush of the fuel system. With AdBlue that counts more than with petrol: it crystallises and is corrosive to some of the metals in a fuel system, and so it doesn't wash out on its own. The fuel filter is cleaned, or replaced where it needs to be; fresh diesel goes in; and your car is tested. Then our engineers fire it up and make sure it runs correctly before leaving. With pumps safe on a busy forecourt and quiet enough for use outside a house at night, most jobs where the motor hasn't run need roughly half an hour once our technicians are there. Your insurer usually wants the engineer's report and the VAT invoice, and you get both once the job is done. Payment comes on the day, with no money upfront. While we travel, have a look at your policy; many carry cover for misfuelling. ## About Bridge End, briefly Bridge End is a suburban area situated on the riverside in Flintshire, Wales, with a mix of semi-detached housing and a population of around 1915 residents.
