--- title: Explained: AdBlue in a Diesel Tank Trotshill canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/trotshill-worcestershire/ location: Trotshill county: Worcestershire latitude: 52.197610 longitude: -2.169670 service: AdBlue in a Diesel Tank updated: 2026-10-12 --- # Why It Happens and How to Prevent It: AdBlue in a Diesel Tank in Trotshill Stop here a minute when the diesel tank already holds AdBlue in it: ignition off, motor off, and call 0333 366 0103. Normally, when your motor has not run, it is drained and fully purged where your vehicle sits around Trotshill. Not happened yet? Further down, the page explains the why it occurs and the ways to avoid it altogether. ## AdBlue in a diesel vehicle, and its separate tank No single liquid but two: that's what plenty of newer diesels around Trotshill and Spetchley carry, with diesel for the motor. Kept in a tank of its own, AdBlue is fed into the exhaust gas to clean it. Separate tanks, separate fillers. Under one flap, next to each other: that is the layout on a lot of cars. On others, AdBlue's filler is under the bonnet or in the boot instead. Filling the diesel side at the pump goes on all the time. Far less often, the AdBlue side gets filled — mostly from a bottle, by someone thinking about where it goes. The slip lives in that gap. ## How AdBlue in the diesel tank occurs in Trotshill Rarely is it carelessness: usually three things coincide. On a drive off Lister Avenue before work, or in the car park outside Lyppard Grange on the way home: that is where the hurried top-up takes place. Why the rush? As AdBlue gets low your car tells you, and if it is gone, limp mode follows. Unfamiliar vehicles are second, as well. Rentals, new motors and company vehicles place their fillers differently, and the hand goes for the cap used on the old one. No part halts the pour after it has started, since a bottle with a spout goes into a diesel filler as readily as an AdBlue one. The bottle fits. It takes seconds, be it in Warndon or right in the heart of Trotshill. ## Telling the AdBlue filler from your diesel filler Look at these before pouring, at a forecourt around Trotshill or a drive out in Tolladine. A few seconds, that's all. - Colour and marking: an AdBlue cap is frequently blue, or says "AdBlue", where a diesel cap usually doesn't. Go by the cap, not where it sits. - Plenty of motors fit AdBlue the smaller filler of the two. - The flap. Look inside the fuel flap for a label. Plenty of cars say there which fuel goes where. - The handbook shows which it lives when the filler isn't next to the diesel cap: the boot, or under the bonnet. - 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 outside Worcester Shrub Hill. ## AdBlue top-ups that never reach the diesel tank The day the light goes on, anywhere in Worcestershire, use this routine. - Stop on level, motor off, with time in hand — never rushing on the side of Dugdale Drive. - Find the AdBlue filler, check the cap, and speak the word "AdBlue" out loud while unscrewing it. It seems silly. It does the trick. - Leave the diesel cap on. If both sit under one flap, check your diesel cap is still closed before you lift the bottle. - Slowly does it, through the bottle's own spout, until it is full or the bottle runs out. - Shut the cap, then check once more — making sure your diesel cap remained closed throughout. After that, start the vehicle. Stop there if you find, at stage two or three, that you've already poured into your diesel side. Never carry on to stage five. ## Trotshill: already put AdBlue in the diesel tank? Short list, then. Top of that: your motor stays off. The fuel pump starts on plenty of diesels the moment your ignition goes on — so keep it off. Topping up with diesel will not weaken it: instead, AdBlue sinks to the bottom of the tank, just where fuel is drawn from. At a forecourt — Tesco, Shell or any other — the attendants will usually help push your car clear, when you ask. Your own driveway around Trotshill is where it stays. Already started? Pull over once it is sensible, then turn off. Trotshill sits under a mile from the M5; on it, take the first exit. About how far did it go? Crossing Trotshill is less a job than a run of under 3 miles towards Worcester, and so say. ## When our engineers get there in Trotshill, what happens? Anywhere your car has stopped, whether by The Lyppard Grange Primary School, beside Lyppard Grange Community Centre or at home, the van comes to it. The answers settle this work and the quote, and so we ask what went in, roughly how much, and if it's run. You get that price on the phone, before anybody sets off. Draining the tank comes next, then a thorough flush of the fuel system. Not like petrol, AdBlue forms crystals and eats at certain fuel-system metals, and neither clears away by itself. That is why it matters more. A test is last: before that, clean diesel is added, and the fuel filter is flushed or replaced as needed. We do not leave until it has been fired up and is running correctly. If the engine has not run, the majority of jobs take about half an hour once we are there, using pumps that are fine on a busy forecourt and quiet enough to use outside a house after dark. Nothing upfront; you settle up on the day. At the end, the VAT invoice and the report from the engineer go to you for the insurer. Plenty of insurance policies include misfuelling cover, so it is worth checking yours while we're on the way. ## About Trotshill Trotshill is a locality situated near Worcester in Worcestershire, with a mix of residential areas and surrounding countryside.
