--- title: AdBlue in a Diesel Tank North Bradley: Explained canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/north-bradley-wiltshire/ location: North Bradley county: Wiltshire latitude: 51.296690 longitude: -2.205690 service: AdBlue in a Diesel Tank updated: 2026-10-16 --- # North Bradley: How Does AdBlue End Up in a Diesel Tank, and How Do You Prevent It? AdBlue already in your diesel tank? Then put this page down a moment, keep the ignition and motor off, then phone 0333 366 0103. Usually, when your motor has not turned, it is emptied and thoroughly rinsed where the vehicle sits in North Bradley. If you are reading before it has happened, the remainder of this page is about why it takes place and how to make sure it does not. ## AdBlue in a diesel car, and its separate tank Plenty of modern diesels around Poles Hole, like those in North Bradley, carry on two fluids; your motor takes just the diesel. Your exhaust, not the engine, is where AdBlue ends up: sprayed into the gas to fresh them, from a separate tank. Each tank has its own filler. 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. Diesel goes in at every filling station call-out, again and again. Much less often, the AdBlue side is filled — mostly from a bottle, by someone working out where it goes. The mistake grows in the gap between the two. ## AdBlue in the diesel tank in North Bradley: how it occurs It is rarely carelessness. Three things tend to line up. First, the warning. Low AdBlue brings a warning from the vehicle, and running dry leads to limp mode — so a rushed top-up, perhaps before work off Westbury Road, or at The Rising Sun on the way home after work. Then, your hand goes for the cap it knew on the old motor — because a rental car, a new vehicle or a company car places the fillers somewhere your last one didn't. A spouted bottle meets no resistance at a diesel filler no more than at an AdBlue one. And so the tip, once begun, carries on. The same few seconds settle it, in the middle of North Bradley or out in Yarnbrook. ## The AdBlue filler and the diesel filler: telling them apart Check these before pouring, on a forecourt in North Bradley or a driveway over in Norleaze. Seconds, that's all. - The cap. The AdBlue cap is often blue, or marked "AdBlue". Your diesel cap normally isn't. Read it instead of going by position. - On plenty of motors, size tells: AdBlue has the smaller filler neck. - The flap. Look inside your fuel flap for a label. Many motors say there which fuel goes where. - The handbook. If your filler is not by the diesel cap, it's in your boot or under the bonnet, 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 Trowbridge, ask before you leave, not when the light comes on. ## How to top up without AdBlue in your diesel tank Anywhere around Wiltshire the light comes on, this is a routine for that day. - Turn off after you park — flat ground, motor off, and never rushed by Southwick Road on the verge. - Find the AdBlue filler, read the cap, and speak the name "AdBlue" out loud as unscrewing it. It sounds silly. It does the trick. - Both behind a single flap? So confirm the lid on the diesel filler is still shut ahead of raising the bottle. - Gently is best, through the bottle's own spout, till it's full or the bottle runs out. - Before starting the car, close the cap and look a second time that the diesel cap was never opened off. Find at stage two or three that it has already gone into your diesel side? So stop right there. Never go on to step five. ## Put AdBlue in your diesel tank in North Bradley already? What follows is a short order of things, beginning with no starting your motor. The fuel pump starts on plenty of diesels the moment the ignition is switched on — so keep it off. AdBlue doesn't mix with diesel — it sinks to the bottom of that tank, where the fuel is pulled from — so don't top up with diesel to dilute it. At a forecourt — Shell, Esso or any other — the staff will normally help roll your car away, if you ask. Your own drive around North Bradley is the place it stays. Stop as soon as it is safe and switch off, if your motor has already run. On the M4, under 15 miles from North Bradley, that means the next exit. Mileage counts — a quick hop across North Bradley is a smaller job than driving under 10 miles towards Bath — so say roughly how far it went. ## What takes place when our engineers arrive around North Bradley Our engineers come to the car wherever it has stopped, whether that is outside North Bradley CofE Primary School, close to Progressive Hall or on your own drive. Those replies decide this work and the price, so our technicians ask what went in, about how much, and whether it's run. That price comes on the call, ahead of any van leaving. Next: a drain, then a thorough flush of the entire system. With AdBlue that matters more than with petrol: it crystallises and is corrosive to some of the metals in a fuel system, and so it doesn't wash out on its own. The filter flushed or, if it must be, replaced; fresh diesel in; then a check of your vehicle. We don't go until it has been fired up and is running properly. Most jobs are done in about half an hour once our technicians get there, as long as the motor hasn't run — and the pumps our technicians use are safe on a busy forecourt and quiet after dark beside a house. Nothing in advance; you settle up on the day. At the end, the VAT invoice and a report from the engineer are handed to you for your insurer. Plenty of insurance policies include misfuelling cover, so it is worth checking yours whilst we are on the way. ## About North Bradley, briefly North Bradley is a village in Wiltshire, situated on the banks of a river at an elevation of 52 metres, with detached housing being the predominant type of accommodation.
