--- title: AdBlue in a Diesel Tank Ladywood: Explained canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/ladywood-midlothian/ location: Ladywood county: Midlothian latitude: 55.835790 longitude: -3.212590 service: AdBlue in a Diesel Tank updated: 2026-10-24 --- # Ladywood: How Does AdBlue End Up in a Diesel Tank, and How Do You Prevent It? AdBlue already in the diesel tank? In that case put this page aside for now, keep your ignition and engine off, and phone 0333 366 0103. Around Ladywood, catching it before the motor runs normally means draining and a full flush on the spot. If you're reading before it has happened, the remainder of this page is about why it happens and how to make sure it does not. ## AdBlue in a diesel vehicle, and its separate tank Diesel goes to your motor — but plenty of modern diesels driven round Ladywood and Kirkhill hold a second fluid as well. The exhaust, not the motor, is where AdBlue ends up: sprayed into the fumes to fresh them, from its own tank. There's a filler for every tank. Under one flap, side by side: that is the layout on a lot of cars. Elsewhere, AdBlue's filler is beneath the bonnet or in the boot instead. At the petrol pump, the diesel side is topped up constantly. Someone who has to stop and think where it goes normally fills the AdBlue side, from a bottle, and much less regularly. The slip lives in that gap. ## AdBlue in the diesel tank around Ladywood: how it occurs Rarely is it carelessness: normally three things line up. The warning comes first. As AdBlue runs low the vehicle tells you, and if it runs out altogether, your vehicle drops into limp mode. So the top-up is done in a hurry: on a driveway off Windsor Terrace before work, or in the car park outside The Cuiken Inn on the way home. The old car's filler is where your hand goes — yet a rental car, a new vehicle or a company car puts the fillers somewhere else. That is the second thing: an unfamiliar motor. No part halts the pour once it has started, because a bottle with a spout goes into a diesel filler as readily as an AdBlue one. The bottle fits. Eastfield or the middle of Ladywood: it is the same few seconds in both. ## Which filler is for AdBlue, and which for diesel? Look at these first, on a forecourt around Ladywood or a drive over in Mauricewood. A few seconds, no more. - The cap. The AdBlue cap is commonly blue, or marked "AdBlue". Your diesel cap normally is not. Read it rather than going by position. - The size. On plenty of vehicles the AdBlue filler neck is the smaller of the two. - Look inside your fuel flap: many motors carry a label there showing which fuel goes where. - In the boot or under the bonnet: that's where the filler is if it's not by the diesel cap, and the handbook says which. - Check with the person who drove it last — before you leave, not when the light comes on — if you pick up a hire or company car from somewhere like the car park outside Newtongrange. ## AdBlue top-ups that never reach your diesel tank A routine for the day the light comes on, wherever around Midlothian that is. - Not in a rush on the side of Eastfield Farm Road, not on a slope, not with your engine running: park and switch off first. - Locate the AdBlue filler, check the cap, and say the word "AdBlue" out loud as unscrewing it. It sounds silly. It works. - The two behind a single flap? Then make sure the lid on your diesel filler stays closed before raising the bottle. - Stop when your tank is topped up or the bottle runs dry; before that, tip gently using its built-in spout. - Only then, start your car: close the cap, check again, and make sure your diesel cap was never opened. Find at stage two or three that it's already gone into your diesel side? Then stop right there. Don't carry on to stage five. ## AdBlue in your diesel tank already, around Ladywood? Do not start the motor: that's how the short order of things starts. Do not switch your ignition on; on plenty of diesels that alone runs the fuel pump. Do not top up with diesel to thin it: AdBlue does not mix with diesel, it sinks to the bottom of the tank, where the fuel is drawn from. If you are at a forecourt, whether it's the Tesco or the Asda, ask the attendants to help push your car clear of the pump. Leave it where it is if you're on your own driveway around Ladywood. Stop as soon as it is safe then switch off, if the engine has already run. On the M8, under 10 miles from Ladywood, that means the next exit. A short hop across Ladywood is a smaller job than a run towards Edinburgh, under 10 miles away, so tell us about how far it went. ## What occurs when our engineers turn up in Ladywood Anywhere the car has stopped, whether outside the local primary school, near Ladywood Leisure Centre or at home, our van comes to it. Which liquid was put in, the quantity, and if it ran: we ask because those answers decide the work and price. On the phone call itself, you hear the price — ahead of dispatch. Then that tank is drained and the system rinsed thoroughly. Not like petrol, AdBlue leaves crystals and attacks some fuel-system metals, and neither clears away unaided. That is why it counts more. Filter cleaned or, where needed, swapped; clean diesel in; then a test of the car. Before we leave, our technicians start it and make sure that it's running properly. Unrun vehicles usually mean a half-hour job from the moment we arrive. The kit is fine on a busy forecourt, and hushed enough for a driveway after dark. Your insurer usually wants an engineer's report and the VAT invoice, and you get both once the job is done. Payment is on the day, with no money upfront. Plenty of insurance policies include misfuelling cover, so it is worth checking yours while we're on the way. ## About Ladywood itself Ladywood is a suburban area in Midlothian, situated on the riverside at an elevation of 179 metres, with Edinburgh approximately 8 miles to the north.

Our engineers drain it where it is — a side street close to Mauricewood Colliery Disaster Memorial, a lay-by on the way to Penicuik Cricket Club, a drive. If you are near a border, or somewhere hard to explain like the back of Kirkhill Bowling Club, ring and ask rather than assuming. ## For Ladywood people, the short version Tip no AdBlue till you have read the cap. Petrol in Diesel drains it where it stands, anywhere in Midlothian, if AdBlue has gone in the diesel tank regardless — so leave the vehicle off then phone 0333 366 0103.
