In that case put this page aside for now, keep the ignition and engine off, then call 0333 366 0103. Around Belmont, finding it before your engine turns usually means draining and a thorough flush on the spot. Nothing happened yet? Further down, the page covers the why it takes place and the how to prevent it altogether. ## Why does AdBlue in a diesel car need its own filler? Many modern diesels on the roads around Belmont and Old Town carry two liquids, not one. Diesel goes to the motor. Kept in a tank of its own, AdBlue is fed into the exhaust stream to clean it. There is a filler for every tank. Plenty of vehicles have a single flap for both, whereas others put the AdBlue filler to your boot or under the bonnet. At the petrol pump, the diesel side gets filled all the time. Far less often, the AdBlue side gets topped up — mostly from a bottle, by someone working out where it goes. It is in the gap that the slip happens. ## How does AdBlue in the diesel tank take place around Belmont? Rarely is it carelessness: usually three things line up. On a drive off Barley Lane before work, or in the car park outside Ashburnham arms heading home: that is where the rushed top-up happens. Why the rush? As AdBlue runs low your car tells you, and if it is empty, limp mode follows. Then, the hand goes for the cap it knew on the old motor — since a rental car, a new vehicle or a company car puts the fillers where your last one did not. A spout-topped bottle finds no resistance at a diesel filler no more than at an AdBlue one. So the pour, once begun, carries on. Whether it occurs in Clive Vale or the middle of Belmont, it's the same few seconds. ## The AdBlue filler and the diesel filler: telling them apart Before you pour anything, whether on a driveway in Broomsgrove or a forecourt around Belmont, check these. They take a couple of seconds. - The cap. The AdBlue cap is often blue, or marked "AdBlue". The diesel cap normally isn't. Read it rather than going by where it sits. - Plenty of motors fit AdBlue the smaller neck of the two. - The flap. Look inside your fuel flap for a label. Many vehicles say there which fuel goes where. - In your boot or under the bonnet: that is where your filler sits if it's not by your diesel cap, and the handbook says which. - The person who drove it last. On a hire or company car collected from somewhere like the car park at Ore, ask before you leave, not when the light comes on. ## Topping up AdBlue without it reaching your diesel tank Wherever around East Sussex the light comes on, this is a routine for that day. - Not in a rush on the side of Pinders Road, 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 as unscrewing it. It sounds daft. It does the trick. - The diesel cap remains on. When the two share a flap, confirm it's shut before the bottle comes up. - Using the bottle's own spout, tip slowly — and stop when it is full or the bottle is empty. - Before starting the vehicle, close the cap and look again that the diesel cap never opened off. Stop there if you find, at step two or three, that you have already poured into the diesel side. Skip step five altogether. ## Put AdBlue in the diesel tank in Belmont already? Brief order, then. First: your engine remains off. The fuel pump runs on many diesels the moment your ignition is switched on — and so keep it off. AdBlue does not mix with diesel — it sinks to the bottom of the tank, where the fuel is pulled from — so don't top up with diesel to dilute it. Ask the attendants to help roll your car away from the pump if you are at a forecourt — the Texaco, the Esso or somewhere else. Leave it where it is if you're on your own drive around Belmont. When your engine has been run by now, pull over somewhere safe then turn the car off. Leave the M20 — under 25 miles out of Belmont — at the first exit. About how far did it go? Crossing Belmont is smaller work than a trip of under 50 miles towards Brighton and Hove, and so tell us. ## Belmont: what happens when we get there The van comes to the vehicle anywhere it has come to rest — your own driveway, near Social Club, or by All Saints CofE Junior Academy. What fluid got in, the amount, and whether it ran: our technicians ask because the answers decide both work and quote. No one sets off before you have heard our quote over the phone. After that: draining, then a thorough flush of the entire system. More than with petrol, it counts with AdBlue: crystals form, certain metals are attacked, and none of that clears away unaided, however long it is left. The fuel filter is flushed, or replaced where it needs to be; clean diesel goes in; and the car is tested. The engine is started next and tested to be sure it runs correctly, all before our technicians head off. Most jobs are done in roughly half an hour after our engineers arrive, as long as your engine hasn't run — and the pumps our technicians use are fine on a busy forecourt and quiet after dark beside 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 money upfront. It's worth looking at your policy while we travel to you: misfuelling cover comes with plenty of policies. ## About Belmont, for a moment Belmont is a suburban area in East Sussex, situated on the southeastern coast of England, with an elevation of around 89 metres.
