A drain plus a thorough flush, done just where your car sits in Conyers Green, is usually all it takes when found before the engine runs. Here in advance? Then what follows covers why it comes about and how to prevent it happening at all. ## Two fillers, two tanks: AdBlue in a diesel motor Many newer diesels on the roads around Conyers Green and East Barton carry two liquids, not one. Diesel goes to your engine. AdBlue goes to the exhaust, where it is sprayed into the gas to fresh it, and it lives in a tank of its own. Each tank has its own filler. Other motors put the AdBlue filler in your boot or under the bonnet; plenty more have both side by side behind one flap. At the pump, the diesel side is topped up all the time. Someone who has to stop and think where it goes usually fills the AdBlue side, from a bottle, and far less frequently. Mistakes happen in the gap between the two. ## Conyers Green: how AdBlue in your diesel tank happens Carelessness rarely causes it. Instead is three things lining up at once. On a driveway off Livermere Road before work, or in the car park outside Bunbury Arms on the way home: that is where the hurried top-up happens. Why the rush? As AdBlue gets low the car warns you, and if it's gone, limp mode kicks in. Then, the hand reaches for the cap it knew on the old car — since a hire car, a new vehicle or a company car places the fillers somewhere your last one did not. A spout-topped bottle finds no resistance at a diesel filler no more than at an AdBlue one. And so the tip, after started, keeps on. The same few seconds settle it, in the middle of Conyers Green or out in Great Barton. ## The AdBlue filler and the diesel filler: telling them apart Whether a Conyers Green forecourt or a driveway out in Timworth, spend a couple of seconds on these before anything goes in. - Blue and marking: an AdBlue cap is regularly blue, or says "AdBlue", where a diesel cap normally doesn't. Go by the cap, not its position. - On plenty of cars, size gives it away: AdBlue has the smaller filler neck. - Lift the filler flap and look for a label — plenty of vehicles mark which belongs in each inlet just there. - The handbook. If the filler is not by the diesel cap, it is in the boot or under the bonnet, and the handbook says which. - Check with the person who drove it last — before you leave, not when the light comes on — when you collect a hire or company car from somewhere like the car park at Thurston. ## Topping up AdBlue without it reaching the diesel tank When the light comes on, anywhere across Suffolk, follow this routine. - Turn off after you park — level ground, engine off, and never in a rush beside Conyers Green at the roadside. - Silly as it sounds, speaking "AdBlue" aloud as you unscrew the cap does the trick — after you've located the filler and read the cap. - If both sit under one flap, check your diesel cap is still closed before you lift the bottle — and leave the vehicle on. - Finish when your tank fills or the bottle runs dry; until then, tip slowly through the own spout. - Before you start the car, shut the cap and look a second time that the diesel cap never came off. Stop there if you find, at step two or three, that you've already poured into the diesel side. Never go on to step five. ## AdBlue in your diesel tank already, in Conyers Green? The short order of things, starting with not starting your motor. On plenty of diesels the ignition alone runs the fuel pump, so don't switch the vehicle on. Don't top up with diesel to dilute it: AdBlue does not mix with diesel, it sinks to the bottom of your tank, where the fuel is drawn from. The attendants at Esso, Tesco or another forecourt will normally lend a hand pushing the vehicle clear when asked. If you're on your own drive in Conyers Green, leave it where it sits. Already started? Pull over once it's sensible, then switch off. On the M11, under 50 miles from Conyers Green, that means the next junction. A short hop across Conyers Green is a smaller job than a run towards Ely, under 25 miles away, so tell us about how far it went. ## What happens when our technicians get there around Conyers Green We come to your car wherever it has stopped, whether that is outside Great Barton Church of England Primary Academy, near Great Barton Village Sign or on your own drive. Our engineers ask what was put in, roughly how much, and if it's run, since those replies determine this work and our quote. During the phone call itself, you hear our quote — before anything else. Draining that tank comes next, then a thorough flush of the system. More than with petrol, it matters here: the crystals build up, certain metals are attacked, and nothing clears away unaided, no matter how long it is left. The filter is cleaned, or replaced where it needs to be; clean diesel goes in; and the vehicle is tested. Your engine is started next and tested to be sure it runs correctly, all before our engineers leave. With pumps fine on a busy forecourt and quiet enough for use outside a house at night, most jobs in which the engine hasn't run take about half an hour after our engineers arrive. Your insurer will ask for the engineer's report and the VAT invoice, and both are yours once this job is done. Payment is on the day, with no deposit. It's worth looking at your policy as the van travels to you: misfuelling cover comes with plenty of policies. ## About Conyers Green, for a moment Conyers Green is a small village in Suffolk, situated inland at an elevation of 72 metres, and is located near the villages of Great Barton, Colton, and Cattishall.
