Read This canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/weston-turville-buckinghamshire/ location: Weston Turville county: Buckinghamshire latitude: 51.790360 longitude: -0.761080 service: AdBlue in a Diesel Tank updated: 2026-10-04 --- # Avoiding AdBlue in a Diesel Tank in Weston Turville: Why It Occurs Keep the motor and ignition off and ring 0333 366 0103 first — the rest can wait when AdBlue is already in your diesel tank. Usually, when your engine hasn't turned, it is emptied and thoroughly purged where the vehicle is around Weston Turville. If you are reading before it has happened, the rest of this page is about why it happens and how to make sure it does not. ## AdBlue in a diesel vehicle: two tanks, two fillers Diesel feeds the motor — yet many modern diesels seen round Weston Turville and Bye Green hold another liquid too. Its own tank keeps it, and from there it goes to your exhaust, where a spray cleans the gas. Each tank has its own filler. Under one flap, side by side: that is the arrangement on a lot of cars. Elsewhere, AdBlue's filler sits under the bonnet or in the boot instead. The diesel side is fuelled at the petrol pump all the time. The AdBlue side is fuelled far less frequently, usually from a bottle, and normally by someone who has to stop and think where it goes. That gap is where the mistake lives. ## Weston Turville: how AdBlue in the diesel tank happens Carelessness rarely explains it. Instead is three things coming up at once. Hurry follows from the warning. The car warns you as AdBlue runs low, and a dry tank sends it into limp mode — so the top-up gets done in a rush, before work on a driveway off Main Street, or heading home in the car park at Five Bells. The old car's cap is where your hand goes — but a hire car, a new vehicle or a company car puts the fillers somewhere else. That is a second factor: a strange vehicle. Third, the spout goes in: a diesel filler or AdBlue filler, it goes in just as easily, and once the tip begins, no part halts it. Whether it happens in West End or the middle of Weston Turville, it's the same few seconds. ## Telling the AdBlue filler from your diesel filler Look at these first, at a forecourt in Weston Turville or a drive over in Worlds End. A few seconds, no more. - Position can mislead; the cap does not. AdBlue ones tend to be blue or carry the name "AdBlue" — diesel caps usually don't. - Plenty of vehicles give AdBlue the smaller neck of the two. - A label inside your fuel flap frequently shows which fuel goes where, on plenty of motors. Check for it. - The handbook shows where it lives if the filler isn't next to the diesel cap: your boot, or under the bonnet. - Picking up a hire or company car, say at the car park at Stoke Mandeville? Ask whoever drove the car last before leaving, rather than once the light goes on. ## Topping up AdBlue without it reaching your diesel tank A routine for the day the light comes on, wherever across Buckinghamshire that is. - Not in a rush on the side of Penfold, not on a slope, not with the motor running: park then switch off first. - Find the AdBlue filler, read the cap, and say the name "AdBlue" aloud while you unscrew it. It sounds silly. It works. - The two behind a single flap? So make sure the lid on your diesel side is still shut before raising the bottle. - Using the bottle's own spout, tip slowly — and stop when it's full or the bottle is empty. - Only then, start the car: close the cap, check again, and make sure your diesel cap was never opened. If at stage two or three you find you have already poured into your diesel side, stop there. Never go on to step five. ## Put AdBlue in the diesel tank around Weston Turville already? Then the order of things is short. Don't start the engine. On many diesels the ignition alone runs the fuel pump, so don't switch it on. AdBlue doesn't mix with diesel — it sinks to the bottom of your tank, where your fuel is pulled from — so do not top up with diesel to thin it. If you are on a forecourt, whether it is the the nearest petrol station or the Shell, ask the staff to help roll the vehicle away from the petrol pump. If you're on your own driveway in Weston Turville, leave the vehicle where it sits. If your engine has already run, stop as soon as it is safe and switch off. The next junction is where to leave if you're on the M40, under 15 miles from Weston Turville. Roughly how far did it go? Hopping across Weston Turville is smaller a job than a trip of under 25 miles towards Milton Keynes, and so say. ## Weston Turville: what happens when we arrive Our engineers come to the car wherever it has stopped, whether that's outside Weston Turville Church of England School, near Weston Turville Village Hall or on your own driveway. Those replies determine this work and the price, and so our technicians ask what was put in, about how much, and whether it has run. During the phone call itself, you are told the quote — ahead of dispatch. Emptying your tank comes next, followed by a thorough flush of the 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 does not wash out on its own. The fuel filter is cleaned, or replaced where it needs to be; fresh diesel goes in; and the vehicle is tested. Your engine is fired up next and tested to confirm it runs properly, all before we leave. Using pumps fine on a busy forecourt and quiet enough to use outside a house at night, most jobs where the motor has not run take about half an hour once our engineers arrive. You pay on the day, with nothing upfront, and get a VAT invoice and an engineer report for your insurer. Many insurance policies include misfuelling cover, so it's worth checking yours while we're on the way. ## About Weston Turville itself Weston Turville is a village in Buckinghamshire, situated on the banks of the River Thame at an elevation of around 100 metres.
