--- title: AdBlue in a Diesel Tank Godwell? Read This canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/godwell-devon/ location: Godwell county: Devon latitude: 50.383740 longitude: -3.907260 service: AdBlue in a Diesel Tank updated: 2026-10-14 --- # Why It Occurs and How to Avoid It: AdBlue in a Diesel Tank in Godwell Leave your engine and ignition off then call 0333 366 0103 first — the rest can wait when AdBlue is already in your diesel tank. Around Godwell, finding it before your motor runs normally leaves draining and a full flush where it stands. If you are reading before it has happened, the rest of this page is about why it happens and how to make sure it doesn't. ## Two fillers, two tanks: AdBlue in a diesel motor Plenty of modern diesels on the roads about Godwell and Ludbrook carry two liquids, not one. Diesel goes to the engine. AdBlue's own tank holds it, and from there it goes to the exhaust, and there a spray treats the fumes. There is a filler on every tank. Many of vehicles share a single flap for the two, whereas some move the AdBlue filler to the boot or under the bonnet. Topping up the diesel side at the pump goes on constantly. The AdBlue side is topped up far less regularly, normally from a bottle, and usually by someone who has to stop and think where it goes. The mistake lives in that gap. ## How does AdBlue in the diesel tank take place in Godwell? Three things tend to come together, and carelessness is seldom one of them. On a driveway off Devon Expressway before work, or in the car park outside Trehill Arms heading home: that is where the hurried top-up happens. What is the reason for the rush? As AdBlue gets low the vehicle warns you, and if it's gone, limp mode kicks in. The old car's filler is where the hand reaches — yet a hire car, a new vehicle or a company car keeps the fillers somewhere else. That is a second factor: a strange vehicle. Nothing halts the tip after it has started, since a bottle with a spout goes into a diesel filler as easily as an AdBlue one. The bottle fits. Whether it happens in Filham or the middle of Godwell, it's the same few seconds. ## How to tell the AdBlue filler from the diesel one Look at these first, on a forecourt in Godwell or a drive over in Ermington. Seconds, that's all. - Check the cap rather than going by where it sits: AdBlue caps are regularly blue or marked "AdBlue", and diesel caps normally are not. - Many motors fit AdBlue the smaller neck of the two. - Open the flap and look for a label — many vehicles show what goes in each inlet right there. - In your boot or under the bonnet: that's where the filler is if it is not by the diesel cap, and the handbook tells you which. - The person who drove the car last. On a hire or company car collected from somewhere like the car park outside Ivybridge, ask before you leave, not when the light comes on. ## AdBlue top-ups that never reach the diesel tank A routine for the day the light comes on, wherever across Devon that is. - Stop somewhere level, engine off, with time in hand — never hurried on the side of Shortlands Way. - Find the AdBlue filler, check the cap, and speak the word "AdBlue" aloud while unscrewing it. It sounds silly. It works. - Leave your diesel cap on. If both sit under one flap, check your diesel cap is still closed before you lift the bottle. - Pour slowly, using the bottle's own spout. Stop when it is full or when the bottle is empty. - Only then, start the vehicle: close the cap, check again, and make sure your diesel cap was never opened. Discover at the second or third stage that AdBlue went into the diesel tank? That is where you stop. Skip step five entirely. ## Already put AdBlue in your diesel tank in Godwell? The short order of things, starting with no starting the engine. The fuel pump runs on plenty of diesels the moment the ignition goes on — so leave it off. Thinning it with extra diesel fails, since AdBlue settles to the bottom rather than blending — and that is where your fuel is sucked from. Ask the attendants to help roll the vehicle away from the petrol pump if you're at a forecourt — the BP, the Tesco or somewhere else. Leave it where it is if you're on your own drive around Godwell. If your motor has already run, stop as soon as it is safe and switch off. The next junction is where to leave when you're on the M5, under 50 miles from Godwell. Tell us about how far it went: a run towards Plymouth, under 15 miles away, is a bigger job than a short hop across Godwell. ## Our arrival in Godwell, and what happens next Wherever your car came to rest, whether by Stowford School, near The Donkey Sanctuary or on your own drive, our van travels to it. Those answers settle the work and our quote, and so our engineers ask what got in, roughly how much, and whether it's run. On the phone call itself, you hear our quote — ahead of anything else. Your system is then flushed thoroughly, once that tank is emptied. With AdBlue that counts more than with petrol: it crystallises and is corrosive to some of the metals in a fuel system, so it does not wash out on its own. Testing comes at the end: before that, fresh diesel is added, and the fuel filter is cleaned or changed as needed. Before leaving, our technicians fire it up and check that it's running properly. If your engine hasn't run, most jobs take about half an hour once we are there, using pumps that are safe on a working forecourt and quiet enough to use outside a house at night. You pay on the day, with nothing upfront, and get a VAT invoice and an engineer report for your insurer. Before we get there, have a look at your policy; plenty carry cover for misfuelling. ## About Godwell, briefly Godwell is a locality in Devon, situated inland at an elevation of 52 metres, approximately 10 miles north of Plymouth.
