--- title: AdBlue in a Diesel Tank Dymchurch? Read This canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/dymchurch-kent/ location: Dymchurch county: Kent latitude: 51.024560 longitude: 0.995460 service: AdBlue in a Diesel Tank updated: 2026-10-11 --- # How It Happens and How to Avoid It: AdBlue in a Diesel Tank in Dymchurch Leave the engine and ignition off then phone 0333 366 0103 now — the rest can wait if AdBlue is already in your diesel tank. In Dymchurch, finding it before your engine turns usually leaves a drain and a thorough flush on the spot. If you are reading before it has happened, the rest of this page is about why it occurs and how to make sure it does not. ## Why does AdBlue in a diesel motor need its own filler? Many newer diesels on the roads round Dymchurch and Donkey Street carry two liquids, not one. Diesel goes to the engine. Your exhaust, not your engine, is where AdBlue ends up: sprayed into the fumes to clean it, from a separate tank. Different tanks, separate fillers. Plenty of vehicles have a single flap for both, while others move the AdBlue filler to your boot or under the bonnet. Diesel goes in on each filling station visit, week in, week out. The AdBlue side is filled far less commonly, normally from a bottle, and usually by somebody who has to stop and think where it goes. It's in that gap that the error lives. ## AdBlue in your diesel tank around Dymchurch: how it takes place It is seldom carelessness. Three things tend to line up. Haste comes from the warning. The car warns you as AdBlue runs low, and an empty tank puts the vehicle into limp mode — so the top-up happens in a rush, before work on a driveway off Orgarswick Avenue, or on the way home in the car park at The City of London. New-to-you vehicles are next, as well. Hire cars, new vehicles and company cars put their fillers differently, and habit goes 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, and so nothing stops the pour after it has started. Whether it happens in High Knocke or the middle of Dymchurch, it's the same few seconds. ## Telling the AdBlue filler from the diesel filler A few seconds is all the checks take — so run through them before you pour anything, on a driveway in St Mary in the Marsh or a forecourt in Dymchurch. - Position misleads; the cap doesn't. AdBlue caps are often blue or bear the name "AdBlue" — diesel ones usually don't. - The size. On plenty of vehicles the AdBlue filler neck is the smaller of the two. - A label inside the fuel flap frequently says which fuel goes where, on many cars. Look for it. - The handbook says where it is when the filler isn't next to your diesel cap: the boot, or under the bonnet. - Ask the person who drove it last — before you leave, not when the light comes on — if you pick up a hire or company car from somewhere like the car park at Westenhanger. ## How to top up without AdBlue in the diesel tank The day the light goes on, anywhere across Kent, use this routine. - Pull in on level, engine off, with time in hand — not rushing on the side of Dymchurch Road. - Locate the AdBlue filler, check the cap, and speak the word "AdBlue" aloud while you unscrew it. It seems daft. It works. - The two behind a single flap? So confirm the cap on your diesel side is still closed before lifting the bottle. - Using the bottle's own spout, tip slowly — and stop when it is full or the bottle is empty. - Close the cap, and look once more — making sure the diesel filler stayed shut the whole time. Only then, start your car. If at stage two or three you find you have already poured into your diesel side, stop there. Leave out step five altogether. ## Dymchurch: already put AdBlue in the diesel tank? Do not start the motor: that's how the short order of things starts. The fuel pump starts on many diesels as soon as the ignition goes on — so keep it off. Topping up with diesel will not weaken it: rather than mixing, AdBlue sinks to the base of your tank, right where the fuel is taken from. If you're at a forecourt, whether it's the the nearest petrol station or the JET, ask the attendants to help roll your car clear of the petrol pump. Leave it where it is if you are on your own driveway around Dymchurch. If the motor has already run, stop as soon as it is safe then switch off. On the M20, under 10 miles from Dymchurch, that means the next junction. Tell us about how far it went: a run towards Canterbury, under 25 miles away, is a bigger job than a short hop across Dymchurch. ## Our arrival around Dymchurch, and what occurs next Outside Dymchurch Primary School, close to Dymchurch Village Hall or on your own drive: wherever the car has stopped, our technicians come to it. Those answers decide the work and the quote, so we ask what was put in, about how much, and whether it has run. That price is given on the call, ahead of any van leaving. The system is then flushed thoroughly, once your tank is drained. Not like petrol, AdBlue forms crystals and attacks certain fuel-system metals, and neither clears away unaided. Hence it counts more. Filter cleaned or, where needed, swapped; fresh diesel in; then a check of your vehicle. We don't go until it has been fired up and is running smoothly. If your engine hasn't run, most jobs take about half an hour once we're there, using pumps that are fine on a busy forecourt and quiet enough to use outside a house after dark. Payment is on the day, not upfront, and you are given the documents your insurer asks for: an engineer report and a VAT invoice. Before we get there, take a look at your policy; plenty carry cover for misfuelling. ## About Dymchurch and where it is Dymchurch is a small village on the coast of Kent, situated near the Romney Marshes and close to the nearby places of High Knocke, St Marys Bay, and Burmarsh.
