Read This canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/littlestone-on-sea-kent/ location: Littlestone-on-Sea county: Kent latitude: 50.981110 longitude: 0.968030 service: AdBlue in a Diesel Tank updated: 2026-10-01 --- # Why It Happens and How to Avoid It: AdBlue in a Diesel Tank in Littlestone-on-Sea AdBlue already in your diesel tank? Then set this page down a moment, keep your ignition and motor off, then phone 0333 366 0103. Caught before your engine runs, it's usually a drain and a thorough flush, done where your car is around Littlestone-on-Sea. If you are reading before it has happened, the rest of this page is about why it takes place and how to make sure it doesn't. ## AdBlue in a diesel motor: two tanks, two fillers Many current diesels on the roads round Littlestone-on-Sea and Lade carry two liquids, not one. Diesel goes to your motor. The exhaust, not your motor, is where AdBlue goes: sprayed into the gas to fresh it, from a separate tank. Each tank has its own filler. On a lot of vehicles the two sit side by side under the same flap; on others the AdBlue filler is in your boot or under the bonnet. The diesel side is filled at the petrol pump all the time. The AdBlue side is topped up far less often, usually from a bottle, and normally by a person who has to stop and think where it goes. The mistake lives in that gap. ## How AdBlue in your diesel tank happens in Littlestone-on-Sea Carelessness seldom causes it. Instead is three things lining 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 drive off Marine Parade before work, or in the car park at The Captain Howey on the way home. Next, the hand goes for the cap it would have used on the old motor — because a rental car, a new motor or a company car puts the fillers somewhere your last one did not. No part stops the tip once it has started, since a bottle with a spout goes into a diesel filler as readily as an AdBlue one. The bottle fits. Whether it takes place in Greatstone-on-Sea or the middle of Littlestone-on-Sea, it is the same few seconds. ## How to tell the AdBlue filler from the diesel one Before you tip anything, whether on a driveway in St Mary in the Marsh or a forecourt in Littlestone-on-Sea, check these. They take a few seconds. - Read the cap instead of going by position: AdBlue caps are frequently blue or marked "AdBlue", and diesel ones usually are not. - Look at the size: the smaller filler neck is, on many motors, the AdBlue one. - The flap. Look inside your fuel flap for a label. Many motors say there which fuel goes where. - The handbook shows where it lives when the filler isn't next to the diesel cap: your boot, or under the bonnet. - Collecting a hire or company car, say at the car park at Appledore (Kent)? Ask whoever drove it last before you set off, not when the light goes on. ## AdBlue top-ups that never reach the diesel tank Wherever in Kent the light comes on, this is a routine for the day. - Not in a rush on the side of Grand Parade, not on a slope, not with your motor running: park and switch off first. - Say "AdBlue" out loud as you unscrew the cap, after you find the AdBlue filler and reading it. Daft, perhaps, but it does the trick. - The two under one flap? So make sure the cap on your diesel filler is still closed before lifting the bottle. - Finish when your tank fills or the bottle runs dry; until then, pour slowly using the own spout. - Only then, start the vehicle: close the cap, check once more, and make sure the diesel cap was never opened. Stop there if you find, at step two or three, that you've already poured into your diesel side. Leave out step five entirely. ## Put AdBlue in the diesel tank around Littlestone-on-Sea already? The short order of things, beginning with no starting the engine. Keep your ignition off as well, because on plenty of diesels switching it on alone runs your fuel pump. Diluting it with more diesel fails, because AdBlue sinks to the bottom rather than mixing — and that's where your fuel is pulled from. The staff at Esso, another forecourt nearby or another forecourt will usually lend a hand pushing your car away when asked. Leave it where it is if you are on your own drive in Littlestone-on-Sea. Where your motor has run by now, pull over somewhere safe and turn the car off. Littlestone-on-Sea sits under 10 miles from the M20; on it, take the first junction. A short hop across Littlestone-on-Sea is a smaller job than a run towards Canterbury, under 25 miles away, and so tell us about how far it went. ## When our technicians arrive around Littlestone-on-Sea, what takes place? Our van reaches the car anywhere it stopped — your own drive, beside Cannon, or outside St Nicholas Church of England Primary Academy. Both the work and our quote rest on three replies — what fluid, which amount, and if it has run — so our technicians ask. You get that price by phone, before anyone sets off. Emptying that tank comes next, followed by a full flush of the fuel system. Much more than with petrol, it matters here: crystals form, certain metals corrode, and none of that washes away on its own, no matter how long it is left. Testing comes at the end: before that, clean diesel is added, and your filter is cleaned or replaced as needed. We don't go until it has been fired up and is running smoothly. Unrun cars usually mean a half-hour visit after arrival. The equipment is fine on a busy forecourt, and quiet enough for a driveway late at night. You pay on the day, with nothing upfront, and get a VAT invoice and an engineer report for your insurer. Wrong-fuel cover is included in plenty of insurance policies — and so use the wait to look at yours. ## About Littlestone-on-Sea itself Littlestone-on-Sea is a small coastal village in Kent, situated on the Romney Marsh coastline at an elevation of around 4 metres.
