Normally, if the motor has not turned, it's emptied and thoroughly cleaned where the car is in Muscliffe. Not happened yet? Below, the rest of the page explains the reasons it happens and the how to avoid it for good. ## Why does AdBlue in a diesel car need its own filler? Many current diesels on the roads around Muscliffe and Throop carry two liquids, not one. Diesel goes to the motor. AdBlue's own tank holds it, and from there it is sent to the exhaust, and there spraying treats the gas. Separate tanks, separate fillers. Some motors keep the AdBlue filler in your boot or under the bonnet; plenty of others place the two side by side behind one flap. Diesel gets filled at every filling station visit, week in, week out. A driver who has to stop and think where it goes normally fills the AdBlue side, from a bottle, and far less commonly. That gap is where the slip lives. ## AdBlue in your diesel tank in Muscliffe: how it occurs Carelessness seldom explains it. What does is three things coming up together. The warning comes first. As AdBlue runs low the car tells you, and if it runs out altogether, the vehicle goes into limp mode. So the top-up is done in a hurry: on a driveway off Iwerne Close before work, or in the car park at The Broadway on the way home. Then the car is new. A hire car, a new vehicle or a company car puts the fillers where your last one did not, and your hand reaches for the cap it would have used on the old one. Nothing halts the tip once it has started, since a bottle with a spout goes into a diesel filler as readily as an AdBlue one. The bottle fits. The same few seconds settle it, in the middle of Muscliffe or out in Muscliff. ## Which filler is for AdBlue, and which for diesel? Before you pour anything, whether on a driveway in Moordown or a forecourt in Muscliffe, check these. They take a few seconds. - The cap. The AdBlue cap is regularly blue, or marked "AdBlue". The diesel cap usually isn't. Read it instead of going by where it sits. - Check the size: the smaller neck is, on plenty of vehicles, the AdBlue one. - A label inside the fuel flap frequently shows which fuel goes where, on many vehicles. Look for it. - In your boot or under the bonnet: that is where your filler is if it's not by the diesel cap, and the handbook says which. - The person who drove it last. On a hire or company car picked up from somewhere like the car park at Bournemouth, ask before you leave, not when the light comes on. ## How to top up without AdBlue in your diesel tank For the day the light comes on — wherever it is around Dorset — a routine to follow. - Turn off after you park — level ground, motor off, and never rushed by Cerne Close at the roadside. - Locate the AdBlue filler, check the cap, and speak the word "AdBlue" aloud as unscrewing it. It sounds silly. It works. - Both under one flap? So confirm the lid on your diesel side stays shut before raising the bottle. - Using the bottle's own spout, tip slowly — and stop when it is full or the bottle is empty. - Close the cap and check again. Make sure your diesel cap was never opened. Only then start the car. Stop there if you find, at stage two or three, that you have already poured into the diesel side. Don't go on to step five. ## Put AdBlue in your diesel tank around Muscliffe already? Brief order, then. First: your engine stays off. Don't switch your ignition on; on many diesels that alone runs the fuel pump. Filling up with diesel won't dilute it: instead, AdBlue sinks to the bottom of your tank, just where fuel is taken from. Ask the attendants to help push the car clear of the pump if you're at a forecourt — the Asda Express, the Esso or somewhere else. Your own driveway in Muscliffe is where it should stay. Already started? Stop when it is sensible, then turn off. Muscliffe sits under 25 miles from the M27; on it, use the first exit. Tell us about how far it went: a run towards Salisbury, under 25 miles away, is a bigger job than a short hop across Muscliffe. ## Our arrival around Muscliffe, and what happens next Our engineers come to the car wherever it has stopped, whether that is outside The Epiphany School, near Kingfisher Barn Visitor Centre or on your own drive. What liquid was put in, the amount, and whether it ran: our technicians ask because those replies set the work and price. You get that price by phone, before anybody heads out. The system is then cleaned thoroughly, once that tank is emptied. Not like petrol, AdBlue leaves crystals and attacks certain fuel-system metals, and none of that clears out by itself. That is why it counts more. Once the filter has been cleaned — or replaced, if required — fresh diesel is added, and then your vehicle gets tested. We don't leave until it has been fired up and is running smoothly. Most jobs are done in roughly half an hour once we get there, as long as the engine has not run — and the pumps our engineers use are safe on a live forecourt yet quiet after dark outside a house. The insurer will ask for the engineer's report and the VAT invoice, and you get both at the end. Payment comes on the day, with no deposit. Wrong-fuel cover is included in many insurance policies — so use the wait to look at yours. ## About Muscliffe, for a moment Muscliffe is a coastal suburban area in Dorset, situated near the city of Bournemouth and close to the nearby places of Muscliff, Red Hill, and Mill Throop.
