Read This canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/camp-hill-warwickshire/ location: Camp Hill county: Warwickshire latitude: 52.526780 longitude: -1.501560 service: AdBlue in a Diesel Tank updated: 2026-10-12 --- # How It Occurs and How to Prevent It: AdBlue in a Diesel Tank in Camp Hill AdBlue already in the diesel tank? In that case put this page aside for now, leave your ignition and engine off, and call 0333 366 0103. A drain and a thorough flush, carried out right where your car stands in Camp Hill, is usually all it takes when found before the engine runs. If you're 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 Diesel goes to the motor — but plenty of current diesels driven round Camp Hill and Plough Hill carry another fluid too. AdBlue's own tank keeps it, and from there it is sent to your exhaust, and there spraying cleans the fumes. Different tanks, different fillers. Many of cars share a single flap for the two, whereas some put the AdBlue filler to your boot or under the bonnet. The diesel side is topped up at the petrol pump all the time. Rarely filled, AdBlue usually comes from a bottle, poured by a driver who has to stop and think what filler to use. The slip lives in that gap. ## How AdBlue in the diesel tank takes place around Camp Hill It's hardly ever carelessness. Three things tend to line up. The warning comes first. As AdBlue runs low the car 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 drive off Edinburgh Road before work, or in the car park at The Midland Railway on the way home. Unfamiliar cars are second, too. Hire cars, new motors and company vehicles place their fillers differently, and the hand reaches for the cap used on the old one. And the bottle fits. A bottle with a spout goes into a diesel filler as easily as an AdBlue one, so nothing stops the pour once it has started. The same few seconds decide it, in the middle of Camp Hill or out in Whittleford. ## How to tell the AdBlue filler from the diesel one Check these before pouring, on a forecourt around Camp Hill or a driveway over in Robinsons End. Seconds, no more. - The cap. The AdBlue cap is frequently blue, or marked "AdBlue". The diesel cap normally isn't. Read it rather than going by where it sits. - Check the size: the smaller filler neck is, on many vehicles, the AdBlue one. - The flap. Look inside your fuel flap for a label. Plenty of motors say there which fuel goes where. - In the boot or under the bonnet: that's where your filler is if it is not by the diesel cap, and the handbook says which. - The person who drove the car last. On a hire or company car picked up from somewhere like the car park at Nuneaton, ask before you leave, not when the light comes on. ## Topping up AdBlue without it reaching the diesel tank When the light comes on, wherever around Warwickshire, use this routine. - Park and switch off. Not on a slope, not with your engine running, and not in a rush on the side of Queen Elizabeth Road. - Find the AdBlue filler and read the cap. Say "AdBlue" out loud as you unscrew it. It sounds silly and it works. - The diesel cap remains on. When the two sit under a flap, confirm it's closed before lifting the bottle. - Pour slowly, using the bottle's own spout. Stop when it is full or when the bottle is empty. - Before starting your car, shut the cap and check a second time that the diesel cap was never came off. If at stage two or three you find you have already poured into the diesel side, stop there. Never go on to stage five. ## Already put AdBlue in the diesel tank around Camp Hill? Short order, then. Top of that: the engine stays unstarted. The fuel pump starts on many diesels as soon as the ignition goes on — so keep it off. Filling up with diesel won't weaken it: instead, AdBlue drops to the bottom of your tank, right where fuel is taken from. Ask the attendants to help roll your car away from the petrol pump if you are on a forecourt — the Texaco, the another forecourt nearby or anywhere else. Your own driveway in Camp Hill is the place it stays. Stop as soon as it is safe then switch off, if the engine has already run. Camp Hill sits under 5 miles from the M6; on it, take the first exit. A short hop across Camp Hill is a smaller job than a run towards Coventry, under 10 miles away, so tell us about how far it went. ## When we arrive in Camp Hill, what takes place? The van comes to the vehicle anywhere it stopped — your own drive, near Stockingford Community Centre, or by Camp Hill Primary School. Those replies determine the work and the quote, and so our technicians ask what got in, about how much, and whether it has run. You get that quote by phone, before anybody sets off. Your system is then flushed thoroughly, after that tank is cleared. With AdBlue that counts 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. A test comes last: before that, fresh diesel goes in, and the fuel filter is cleaned or replaced as needed. After that our technicians fire it up and confirm it runs properly before we leave. Most jobs are finished in roughly half an hour once our technicians get there, as long as the motor has not run — and the pumps our technicians use are safe on a busy forecourt and quiet after dark outside a house. Paying happens on the day, not upfront, and you receive the paperwork your insurer wants: an engineer's report and a VAT invoice. Misfuelling cover is part of many insurance policies — and so make use of the wait to look at yours. ## About Camp Hill and where it is Camp Hill is a suburban area situated on the outskirts of Coventry in Warwickshire, with a lakeside setting that adds to its natural beauty.
