Read This canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/charlton-park-gloucestershire/ location: Charlton Park county: Gloucestershire latitude: 51.882410 longitude: -2.063790 service: AdBlue in a Diesel Tank updated: 2026-10-04 --- # How It Happens and How to Avoid It: AdBlue in a Diesel Tank in Charlton Park Leave your engine and ignition off then ring 0333 366 0103 first — the rest can wait when AdBlue is already in the diesel tank. A drain and a thorough flush, carried out right where your car sits around Charlton Park, is normally all it needs when found before the motor runs. Reading before the event? In that case what follows covers how it happens and how to stop it happening at all. ## AdBlue in a diesel car, and its separate tank Diesel goes to your engine — but plenty of newer diesels driven round Charlton Park and Bafford carry another liquid as well. Your exhaust, not your engine, is where AdBlue ends up: sprayed into the gas to fresh them, from a separate tank. Each tank has its own filler. Some vehicles keep the AdBlue filler in the boot or under the bonnet; plenty of others place the two together behind one flap. The diesel side is fuelled at the petrol pump all the time. The AdBlue side is filled far less often, usually from a bottle, and normally by somebody who has to stop and think where it goes. That gap is where the error lives. ## How does AdBlue in the diesel tank take place in Charlton Park? Carelessness rarely causes it. Instead is three things coming up together. 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 The Avenue before work, or in the car park at The Royal on the way home. Then the car is strange. A hire car, a new car or a company car puts the fillers where your last one didn't, and your hand gets to for the cap it would have used on the old one. Nothing halts the pour once it has started, because a bottle with a spout goes into a diesel filler as easily as an AdBlue one. The bottle fits. Moor End or the middle of Charlton Park: it is the same few seconds either way. ## How to tell the AdBlue filler from the diesel one Before you tip anything, whether on a drive in Leckhampton or a forecourt around Charlton Park, check these. They take a few seconds. - Colour and lettering: an AdBlue cap is regularly blue, or says "AdBlue", where a diesel cap usually doesn't. Trust the cap, not where it sits. - Many cars give AdBlue the smaller neck of the two. - Look inside your fuel flap: plenty of cars carry a label there showing which fuel goes where. - The handbook. If the filler isn't by the diesel cap, it is in your boot or under the bonnet, and the handbook says which. - The person who drove the vehicle last. On a hire or company car picked up from somewhere like the car park at Cheltenham Spa, ask before you leave, not when the light comes on. ## Keeping AdBlue out of the diesel tank when you top up The day the light comes on, anywhere in Gloucestershire, follow this routine. - Not in a rush on the side of Moorend Road, not on a slope, not with the engine running: park and switch off first. - Daft as it sounds, speaking "AdBlue" out loud while you unscrew the cap does the trick — after you have located your filler and read the cap. - The two under one flap? So confirm the lid on the diesel side is still closed before raising the bottle. - Tip slowly, using the bottle's own spout. Stop when it is full or when the bottle is empty. - Only then, start the car: close the cap, check a second time, and make sure your diesel cap was never opened. Spot at stage two or three that it has already gone into your diesel side? Then stop right there. Do not go on to step five. ## AdBlue in the diesel tank already, in Charlton Park? What follows is a short order of things, starting with no starting the motor. Do not switch your ignition on; on many diesels that alone runs the fuel pump. Filling up with diesel won't thin it: instead, AdBlue drops to the bottom of that tank, just where fuel is taken from. At a forecourt — Esso, BP or another — the staff will usually help roll the vehicle clear, when you ask. Your own drive around Charlton Park is the place it stays.

Our technicians come to the car wherever it has stopped, whether that's outside Naunton Park Primary School, close to Cheltenham Croquet Club or on your own driveway. Our technicians ask what went in, about how much, and if it's run, because the replies settle this work and the price. No one heads out before you've had our price by phone. The system is then rinsed thoroughly, after your tank is drained. More than with petrol, it matters with AdBlue: crystals build up, certain metals are attacked, and none of that clears away on its own, no matter how long it is left. The filter is flushed, or replaced where it needs to be; fresh diesel goes in; and your car is tested. Before leaving, our engineers fire it up and make sure that it is running properly. If your engine has not run, the majority of jobs take about half an hour once we are there, using pumps that are safe on a working forecourt and quiet enough to use outside a house after dark. You pay on the day, with nothing upfront, and get a VAT invoice and an engineer report for your insurer. Wrong-fuel cover is part of many insurance policies — and so use the wait to check yours. ## About Charlton Park, for a moment Charlton Park is a suburban area located on the outskirts of Gloucester, situated near the riverside in Gloucestershire.
