--- title: AdBlue in a Diesel Tank Goring-by-Sea: Explained canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/goring-by-sea-west-sussex/ location: Goring-by-Sea county: West Sussex latitude: 50.815800 longitude: -0.432170 service: AdBlue in a Diesel Tank updated: 2026-10-02 --- # Goring-by-Sea: How Does AdBlue End Up in a Diesel Tank, and How Do You Prevent It? Pause here for a moment if the diesel tank already has AdBlue in it: ignition off, motor off, then call 0333 366 0103. A drain and a thorough flush, done just where your car stands in Goring-by-Sea, is normally all it takes if caught before the engine runs. If you are reading before it has happened, the remainder of this page is about why it occurs and how to make sure it does not. ## AdBlue in a diesel vehicle, and its separate tank Many newer diesels on the roads round Goring-by-Sea and Durrington-on-Sea Sta carry two liquids, not one. Diesel goes to your motor. Your exhaust, not your motor, is where AdBlue goes: dosed into the fumes to fresh them, from a separate tank. There's a filler for every tank. Plenty of cars share a single flap for the two, while others move the AdBlue filler to the boot or under the bonnet. The diesel side is fuelled at the petrol pump all the time. The AdBlue side is filled far less regularly, usually from a bottle, and normally by someone who has to stop and think where it goes. The mistake grows in the gap between the two. ## How does AdBlue in the diesel tank occur in Goring-by-Sea? Seldom is it carelessness: usually three things coincide. The warning comes first. As AdBlue runs low the vehicle tells you, and if it runs out altogether, the car drops into limp mode. So the top-up is done in a hurry: on a driveway off Aldsworth Avenue before work, or in the car park at The Bull's Head on the way home. Then, the hand reaches for the cap it knew on the old vehicle — because a hire car, a new vehicle or a company car places the fillers somewhere your last one didn't. 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 after it has started. Ferring or the middle of Goring-by-Sea: it is the same few seconds in both. ## The AdBlue filler and your diesel filler: telling them apart A few seconds is all these take — so run through them before you pour anything, on a driveway in East Kingston or a forecourt in Goring-by-Sea. - The cap. The AdBlue cap is frequently blue, or marked "AdBlue". Your diesel cap usually is not. Read it rather than going by position. - Check the size: the smaller neck is, on plenty of cars, the AdBlue one. - The flap. Look inside your fuel flap for a label. Plenty of vehicles say there which fuel goes where. - In the boot or under the bonnet: that is where the filler is if it's not by the diesel cap, and the handbook says which. - The person who drove it last. On a hire or company car picked up from somewhere like the car park outside the nearest station, ask before you leave, not when the light comes on. ## How to top up without AdBlue in the diesel tank A routine for the day the light comes on, wherever across West Sussex that is. - Park then switch off. Not on a slope, not with the engine running, and not in a rush on the side of Goring Street. - Find the AdBlue filler and read the cap. Say "AdBlue" out loud as you unscrew it. It sounds daft and it works. - The two under one flap? So make sure the lid on your diesel filler is still shut ahead of raising the bottle. - Finish when the tank is topped up or the bottle runs dry; until then, tip slowly using its own spout. - Shut the cap, then check again — making sure the diesel cap remained closed throughout. After that, start the vehicle. If at step two or three you find you have already poured into the diesel side, stop there. Skip stage five entirely. ## Already put AdBlue in the diesel tank in Goring-by-Sea? Brief list, then. First: the engine remains unstarted. On plenty of diesels the ignition alone runs the fuel pump, and so do not switch it on. AdBlue doesn't mix with diesel — it sinks to the bottom of your tank, where the fuel is drawn from — so do not top up with diesel to thin it. The staff at Steeles of Worthing, Co-op or any forecourt will usually help pushing the car clear if asked. Leave it where it is if you're on your own driveway around Goring-by-Sea. Stop as soon as it is safe and switch off, if your engine has already run. Come off the M23 — under 25 miles out of Goring-by-Sea — at the next junction. A short hop across Goring-by-Sea is a smaller job than a run towards Brighton and Hove, under 15 miles away, and so tell us about how far it went. ## Goring-by-Sea: what happens when our technicians get there Wherever your car has stopped, whether outside Goring-By-Sea CofE (Aided) Primary School, beside The Church of Jesus Christ of Latter-day Saints or at home, our van travels to it. Those replies settle this work and the price, and so our technicians ask what got in, about how much, and if it has run. The price comes over the phone, before any van leaves. Then your tank is drained and the system flushed thoroughly. Much more than with petrol, it counts here: the crystals build up, certain metals corrode, and none of that washes away on its own, however long it is left. Testing comes at the end: before that, clean diesel is added, and your filter is flushed or changed if necessary. Your engine is started next and tested to confirm it runs properly, all before we head off. Unrun cars usually need a half-hour job from arrival. The kit is safe on a live filling station, and quiet enough for a driveway after dark. You pay on the day, with nothing upfront, and get a VAT invoice and an engineer report for your insurer. It is worth checking your insurance while we travel to you: misfuelling cover is included with many policies. ## About Goring-by-Sea, briefly Goring-by-Sea is a coastal suburban area in West Sussex, situated near the mouth of the River Adur and close to the South Downs National Park.
