A drain and a full flush, carried out just where your car sits around East Malling Heath, is normally all it needs when found before your motor runs. If you are reading before it has happened, the rest of this page is about why it occurs and how to make sure it does not. ## Why does AdBlue in a diesel car need its own filler? Not one fluid but two: that is how plenty of modern diesels near East Malling Heath and East Malling run, with diesel feeding your engine. AdBlue's own tank keeps it, and from there it goes to the exhaust, and there a spray treats the gas. Each tank comes with one filler of its own. On a lot of vehicles the two sit side by side under the same flap; on others the AdBlue filler is in the boot or under the bonnet. The diesel side is filled at the pump all the time. Far less often, the AdBlue side gets topped up — mostly from a bottle, by a person thinking about where it goes. That gap is where the slip lives. ## How does AdBlue in the diesel tank happen around East Malling Heath? Carelessness rarely explains it. Instead is three things lining up together. To start with, the warning. Low AdBlue triggers a warning from the vehicle, and running out leads to limp mode — hence a rushed top-up, maybe before work off Wateringbury Road, perhaps at North Pole on the way home after work. Next, the hand reaches for the cap it knew on the old motor — since a rental car, a new vehicle or a company car places the fillers where your last one did not. A spout-topped bottle meets no obstacle at a diesel filler no more than at an AdBlue one. And so the pour, after begun, carries on. The same few seconds settle it, in the middle of East Malling Heath or out in Livesey Street. ## How to tell the AdBlue filler from the diesel one A couple of seconds is all the checks take — so run through them before you tip anything, on a drive in Mill Street or a forecourt in East Malling Heath. - Blue and marking: an AdBlue cap is often blue, or says "AdBlue", where a diesel cap usually doesn't. Trust the cap, not its position. - Check the size: the smaller neck is, on plenty of motors, the AdBlue one. - Check inside your fuel flap: many cars carry a label there saying which fuel goes where. - The handbook says where it lives if the filler is not next to your diesel cap: the boot, or under the bonnet. - The person who drove the vehicle last. On a hire or company car picked up from somewhere like the car park at East Malling, ask before you leave, not when the light comes on. ## Keeping AdBlue out of the diesel tank when you top up When the light goes on, wherever across Kent, follow this routine. - Not in a rush on the side of Beacon Avenue, not on a slope, not with the motor running: park and switch off first. - Daft as it sounds, speaking "AdBlue" out loud as you unscrew the cap works — after you have located the filler and read it. - The diesel cap stays on. Where the two sit under a flap, make sure it's shut before the bottle comes up. - Using the bottle's own spout, tip slowly — and stop when it's full or the bottle is empty. - Only then, start your car: close the cap, check once more, and make sure the diesel cap was never opened. Discover during the second or third step that the bottle went in the diesel tank? That's where you stop. Never go on to stage five. ## AdBlue in your diesel tank already, around East Malling Heath? Then the order of things is short. Don't start your engine. Keep the ignition off as well, because on many diesels switching it on alone starts the pump. AdBlue does not mix with diesel — it sinks to the bottom of your tank, where your fuel is drawn from — so don't top up with diesel to thin it. Ask the attendants to help roll your car clear of the pump if you are on a forecourt — the JET, the Esso or anywhere else. Your own drive in East Malling Heath is where it should stay. If your motor has already run, stop as soon as it is safe and switch off. Leave the M20 — under 3 miles out of East Malling Heath — at the first junction. Tell us about how far it went: a run towards Southend-on-Sea, under 25 miles away, is a bigger job than a short hop across East Malling Heath. ## Our arrival around East Malling Heath, and what takes place next Our technicians come to the vehicle wherever it has stopped, whether that is outside The Discovery School, close to St James the Great or on your own drive. What liquid went in, the amount, and whether it ran: our engineers ask because the replies decide the work and quote. You get that quote by phone, before anybody heads out. The fuel system is then purged thoroughly, once your tank is cleared. More than with petrol, it counts here: crystals build up, some metals are attacked, and nothing washes out unaided, no matter how long it is left. The filter cleaned or, if it must be, replaced; clean diesel in; then a check of the car. Before leaving, our engineers fire it up and confirm that it is running correctly. Unstarted vehicles usually need a half-hour job after arrival. The equipment is fine on a busy filling station, and hushed enough for a driveway after dark. 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 as the van travels to you: misfuelling cover comes with plenty of policies. ## About East Malling Heath itself East Malling Heath is a locality in Kent, situated inland at an elevation of 86 metres, and is characterized by its predominantly detached housing.
