--- title: AdBlue in a Diesel Tank Cellarhill? Read This canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/cellarhill-kent/ location: Cellarhill county: Kent latitude: 51.327990 longitude: 0.804710 service: AdBlue in a Diesel Tank updated: 2026-10-25 --- # How It Occurs and How to Prevent It: AdBlue in a Diesel Tank in Cellarhill Keep your motor and ignition off and ring 0333 366 0103 now — the rest can wait if AdBlue is already in the diesel tank. Around Cellarhill, catching it before the engine runs normally leaves draining and a full flush on the spot. Here in advance? In that case what follows explains why it comes about and how to stop it ever happening. ## AdBlue in a diesel car: two tanks, two fillers Diesel goes to your motor — but plenty of newer diesels seen around Cellarhill and Teynham Street carry another fluid as well. AdBlue's own tank keeps it, and from there it is sent to the exhaust, and there a spray treats the fumes. There's a filler for every tank. Plenty of motors share a single flap for both, whereas some move the AdBlue filler to your boot or under the bonnet. Diesel goes in at each forecourt visit, again and again. Seldom filled, AdBlue usually goes in out of a bottle, poured by a driver who has to stop and think which filler it needs. That gap is where the mistake lives. ## AdBlue in the diesel tank around Cellarhill: how it happens It's rarely carelessness. Three things tend to line up. On a drive off Marconi Crescent before work, or in the car park outside Dover Castle on the way home: that is where the hurried top-up happens. Why the rush? As AdBlue runs low the vehicle warns you, and if it is empty, limp mode kicks in. Unfamiliar motors come next, too. Hire cars, new vehicles and company vehicles put their fillers in new places, and habit goes for the cap used on the old one. A spout-topped bottle finds no resistance at a diesel filler no more than at an AdBlue one. And so the pour, after begun, carries on. Whether it takes place in Teynham or the middle of Cellarhill, it's the same few seconds. ## The AdBlue filler and the diesel filler: telling them apart A few seconds is all the checks take — so run through them before you tip anything, on a drive in Radfield or a forecourt in Cellarhill. - Colour and lettering: an AdBlue cap is regularly blue, or says "AdBlue", where a diesel cap normally doesn't. Trust the cap, not its position. - The size. On plenty of cars the AdBlue filler neck is the smaller of the two. - Check inside the fuel flap: plenty of vehicles have a label there showing which fuel goes where. - In the boot or under the bonnet: that is where your filler is if it's not by the diesel cap, and the handbook says which. - Ask the person who drove it last — before you leave, not when the light comes on — when you pick up a hire or company car from somewhere like the car park at Teynham. ## Keeping AdBlue out of the diesel tank when you top up A routine for the day the light comes on, wherever across Kent that is. - Switch off after you park — flat ground, engine stopped, and not in a rush by Nobel Close on the verge. - Daft as it sounds, saying "AdBlue" out loud as you unscrew the cap works — after you have found your filler and read it. - Leave the diesel cap on. If both sit under one flap, check your diesel cap is still closed before you lift the bottle. - Stop when that tank fills or the bottle runs dry; until then, pour 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 step two or three that it has already gone into your diesel side? Then stop right there. Don't go on to step five. ## AdBlue in your diesel tank already, in Cellarhill? Don't start your motor: that's where the short order of things begins. The fuel pump runs on many diesels the moment the ignition goes on — and so keep it off. Topping up with diesel won't weaken it: rather than mixing, AdBlue sinks to the base of that tank, just where the fuel is taken from. At a forecourt — Norton Cross Service Station, BP or another — the attendants will normally help push your car clear, when you ask. Leave it where it is if you are on your own driveway around Cellarhill. Where your engine has run already, pull over somewhere safe then switch the car off. On the M2, under 3 miles from Cellarhill, that means the next junction. About how far did it go? Hopping across Cellarhill is less a job than a trip of under 15 miles to Canterbury, so say. ## What happens when our technicians get there in Cellarhill Anywhere the vehicle came to rest, be it outside Teynham Parochial Church of England Primary School, beside Teynham Village Hall or at home, the van comes to it. What liquid got in, the quantity, and whether it ran: we ask since those replies decide the work and quote. You hear that price on the phone, before anybody sets off. Then your tank is emptied and the system cleaned thoroughly. AdBlue crystallises and is corrosive to some of the metals in a fuel system, so it doesn't wash out on its own — which is why that counts more with AdBlue than with petrol. Your filter is flushed, or replaced where it needs to be; clean diesel goes in; and the car is tested. We do not go until it has been fired up and is running smoothly. With pumps fine on a working forecourt and quiet enough for use outside a house at night, most jobs in which your engine has not run take about half an hour after our technicians are there. Paying happens on the day, not upfront, and you are given the paperwork your insurer asks for: an engineer's report and a VAT invoice. While we travel, take a look at your insurance documents; many carry cover for misfuelling. ## About Cellarhill and where it is Cellarhill is a coastal locality in Kent, situated near the towns of Teynham and Canterbury, with semi-detached housing being the predominant type of accommodation.
