--- title: Icy Park: AdBlue in a Diesel Tank, Explained canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/icy-park-devon/ location: Icy Park county: Devon latitude: 50.312960 longitude: -3.834200 service: AdBlue in a Diesel Tank updated: 2026-10-12 --- # AdBlue in a Diesel Tank in Icy Park: Why It Happens and How to Avoid It AdBlue already in your diesel tank? In that case set this page aside for now, keep your ignition and motor off, then phone 0333 366 0103. Caught before your engine runs, it is usually a drain and a thorough flush, done where the vehicle is around Icy Park. Nothing happened yet? Below, the page covers the why it occurs and the how to avoid it for good. ## Two fillers, two tanks: AdBlue in a diesel motor Plenty of newer diesels on the roads around Icy Park and Hatch carry two liquids, not one. Diesel goes to the motor. AdBlue's own tank holds it, and from there it is sent to the exhaust, and there a spray treats the gas. Each tank comes with one filler of its own. On a lot of motors the two sit side by side under the same flap; on others the AdBlue filler is in your boot or under the bonnet. Topping up the diesel side at the pump goes on all the time. The AdBlue side is fuelled far less often, normally from a bottle, and usually by a person who has to stop and think where it goes. It is in that gap that the slip happens. ## Icy Park: how AdBlue in the diesel tank takes place It's hardly ever carelessness. Three things tend to line up. On a driveway off Rock Hill before work, or in the car park at Fisherman's Rest heading home: that's where the rushed top-up takes place. What is the reason for the rush? As AdBlue gets low the vehicle warns you, and once it's gone, limp mode kicks in. New-to-you cars are next, too. Rentals, new motors and company motors put their fillers differently, and habit reaches for the cap it used on the old one. Lastly, the bottle goes in: a diesel filler or AdBlue one, it goes in as easily, and once the tip begins, no part stops it. Whether it happens in Aveton Gifford or the middle of Icy Park, it is the same few seconds. ## How to tell the AdBlue filler from the diesel one A couple of seconds is all these take — so run through them before you pour anything, on a drive in Churchstow or a forecourt around Icy Park. - Position misleads; the cap does not. AdBlue caps are often blue or bear the word "AdBlue" — diesel ones normally do not. - Many cars give AdBlue the smaller filler of the two. - A label inside the fuel flap often says which fuel goes where, on plenty of vehicles. Check for it. - Can't find it beside the diesel inlet? Then look below the bonnet or inside the boot — the owner's manual will say which. - The previous driver knows. Check when you collect a hire car or company car — from Ivybridge's car park, perhaps — rather than when the light comes on. ## AdBlue top-ups that never reach your diesel tank A routine for the day the light comes on, wherever around Devon that is. - Pull in somewhere level, engine off, with time in hand — not hurried on the side of Fore Street. - Silly as it sounds, saying "AdBlue" aloud while you unscrew the cap works — after you have found your filler and read the cap. - The two under one flap? Then confirm the cap on your diesel filler stays shut ahead of raising the bottle. - Finish once your tank is topped up or the bottle runs dry; until then, pour slowly using its own spout. - Before you start the vehicle, close the cap and look again that the diesel cap never came off. Find at stage two or three that it has already gone into your diesel side? Then stop just there. Never go on to step five. ## Icy Park: already put AdBlue in your diesel tank? Don't start the engine: that is where the short order of things begins. Keep the ignition off too, since on plenty of diesels switching it on alone starts the fuel pump. Don't top up with diesel to thin it: AdBlue doesn't mix with diesel, it sinks to the bottom of that tank, where the fuel is pulled from. On a forecourt — Asda Express, BP or any other — the staff will normally help roll your car clear, if you ask. On your own drive in Icy Park? So the car remains put. When the engine has run by now, stop safely then turn the vehicle off. The next junction is where to leave if you're on the M5, under 50 miles from Icy Park. Distance matters — a quick hop across Icy Park is a smaller job than driving under 15 miles to Plymouth — so tell us roughly how far it went. ## Our arrival in Icy Park, and what occurs next Our van reaches your car anywhere it has come to rest — your own drive, beside Aveton Gifford Community Pool, or outside Aveton Gifford CofE Primary School. Which fluid was put in, the amount, and whether it ran: our engineers ask because those replies set both work and price. Nobody sets off until you've heard our price over the phone. Then your tank is cleared and your system cleaned thoroughly. Unlike petrol, AdBlue forms crystals and eats at certain fuel-system metals, and none of that washes out unaided. That is why it matters more. The fuel filter is flushed, or replaced where it needs to be; clean diesel goes in; and your car is tested. Before we leave, we fire it up and check that it's running properly. Most jobs are finished in about half an hour once our technicians arrive, as long as the engine hasn't run — and the pumps we use are fine on a live forecourt and quiet after dark outside a house. The insurer will ask for the engineer's report and your VAT invoice, and both are yours once this job is done. Payment comes on the day, with no deposit. Wrong-fuel cover is included in many insurance policies — and so use the wait to look at yours. ## About Icy Park itself Icy Park is a small locality in Devon, situated on the riverside at an elevation of 34 metres, with terraced housing being the predominant type of accommodation.
