Pause here for a moment when your diesel tank already has AdBlue in it: ignition off, motor off, and phone 0333 366 0103. A drain and a thorough flush, carried out just where the vehicle stands in Norris Green, is usually all it needs when found before your engine runs. Nothing happened yet? Below, the page explains the why it takes place and the ways to avoid it altogether. ## Why does AdBlue in a diesel motor need its own filler? Many newer diesels on the roads about Norris Green and Fazakerley carry two liquids, not one. Diesel goes to your motor. AdBlue's own tank keeps it, and from there it is sent to your exhaust, where spraying cleans the gas. Each tank has its own filler. Some motors put the AdBlue filler in your boot or under the bonnet; plenty more place both together behind one flap. Filling your diesel side at the pump goes on constantly. The AdBlue side is topped up far less frequently, usually from a bottle, and normally by someone who has to stop and think where it goes. It is in that gap that the slip lives. ## AdBlue in the diesel tank in Norris Green: how it occurs Seldom is it carelessness: normally three things coincide. On a drive off Utting Avenue East before work, or in the car park outside The Western Approaches on the way home: that's where the hurried top-up takes place. Why the rush? As AdBlue gets low the vehicle warns you, and if it's empty, limp mode follows. New-to-you cars come next, too. Hire cars, new vehicles and company vehicles put their fillers in new places, and the hand reaches for the cap used on the old one. Lastly, the bottle goes in: a diesel filler or AdBlue filler, it goes in just as easily, and once the tip starts, nothing stops it. It's a few seconds, whether out in Dog and Gun or right in the heart of Norris Green. ## Which filler is for AdBlue, and which for diesel? Before you tip anything, whether on a drive in Gillmoss or a forecourt around Norris Green, check these. They take a couple of seconds. - Where it sits can mislead; the cap does not. AdBlue caps are often blue or bear the name "AdBlue" — diesel caps usually don't. - Look at the size: the smaller filler neck is, on plenty of motors, the AdBlue one. - The flap. Look inside the fuel flap for a label. Many motors say there which fuel goes where. - In the boot or under the bonnet: that is where your filler sits if it is not by your diesel cap, and the handbook says which. - Picking up a hire or company car, say at the car park outside Fazakerley? Ask whoever drove it last before leaving, rather than once the light goes on. ## Keeping AdBlue out of the diesel tank when you top up For the day the light appears — anywhere you are around Merseyside — a simple routine to follow. - Stop somewhere level, engine off, with time in hand — not hurried on the side of Sedgemoor Road. - Locate the AdBlue filler, read the cap, and say the name "AdBlue" out loud while unscrewing it. It seems silly. It does the trick. - The two behind a single flap? Then make sure the lid on the diesel filler stays closed ahead of lifting the bottle. - Gently is best, through the bottle's own spout, until it's full or the bottle is empty. - Only then, start the car: close the cap, check again, and make sure the diesel cap was never opened. Stop there if you find, at stage two or three, that you have already poured into the diesel side. Don't go on to stage five. ## AdBlue in the diesel tank already, around Norris Green? Short list, then. Top of that: the motor remains off. The fuel pump runs on plenty of diesels the moment the ignition is switched on — so leave it off. Topping up with diesel won't dilute it: rather than mixing, AdBlue sinks to the base of your tank, right where the fuel is taken from. Ask the staff to help push your car away from the pump if you're at a forecourt — the the nearest petrol station, the Asda or anywhere else. Your own drive around Norris Green is the place it stays. Where the motor has been run already, pull over safely and switch it off. Come off the M57 — under 3 miles out of Norris Green — at the next junction. Distance matters — a short hop across Norris Green is a smaller job than driving under 5 miles to Liverpool — so tell us about how far it went. ## What takes place when we turn up in Norris Green Our engineers come to your car wherever it has stopped, whether that is outside St Teresa of Lisieux Catholic Primary Academy, close to St Teresa Of The Child Jesus Roman Catholic Church or on your own driveway. Both the work and the price depend on three answers — which liquid, which amount, and if it's run — so our technicians ask. Nobody heads out before you've had the price over the phone. Emptying that tank comes next, followed by a full flush of the system. More than with petrol, it matters with AdBlue: the crystals build up, certain metals are attacked, and none of it washes away unaided, no matter how long it sits. Once the fuel filter is flushed — or renewed, where needed — clean diesel goes in, and finally the vehicle is tested. Before we go, our technicians start the engine and confirm that it is running correctly. Most jobs are done in about half an hour once we get there, provided your engine has not run — and the pumps we use are fine on a live forecourt yet quiet after dark outside a house. You pay on the day, with nothing upfront, and get a VAT invoice and an engineer report for your insurer. It is worth looking at your insurance while we travel to you: misfuelling cover comes with plenty of policies. ## About Norris Green itself Norris Green is a suburban area in Merseyside, located approximately 3.4 miles from Liverpool city centre.
