--- title: AdBlue in a Diesel Tank East Town? Read This canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/east-town-devon/ location: East Town county: Devon latitude: 50.791150 longitude: -3.649470 service: AdBlue in a Diesel Tank updated: 2026-10-19 --- # AdBlue in a Diesel Tank in East Town: How It Occurs and How to Stop It Leave your motor and ignition off then phone 0333 366 0103 first — reading can wait when AdBlue is already in your diesel tank. Caught before the motor runs, it's usually a drain and a thorough flush, done where the vehicle is around East Town. Not happened yet? Further down, the rest of the page covers the reasons it happens and the how to prevent it for good. ## Why does AdBlue in a diesel motor need its own filler? Many current diesels on the roads about East Town and Westwood carry two liquids, not one. Diesel goes to your motor. Kept in a tank of its own, AdBlue is sprayed into the exhaust gas to clean it. There is a filler for each tank. Under one flap, side by side: that is the layout on a lot of motors. Elsewhere, AdBlue's filler is under the bonnet or in the boot instead. At the petrol pump, the diesel side gets filled all the time. A driver who has to stop and think where it goes usually tops up the AdBlue side, from a bottle, and much less often. That gap is where the error lives. ## East Town: how AdBlue in your diesel tank occurs It is seldom carelessness. Three things tend to line up. Hurry follows from the warning. Your car tells you as AdBlue runs low, and an empty tank sends the vehicle into limp mode — so the top-up happens in a rush, before work on a driveway off Blagdon, or heading home in the car park at Crediton Arms. Next, your hand goes for the cap it knew on the old motor — since a rental car, a new car or a company car puts the fillers somewhere your last one didn't. Nothing stops the pour after it has started, because a bottle with a spout goes into a diesel filler as readily as an AdBlue one. The bottle fits. It takes seconds, whether out in Crediton or right in the heart of East Town. ## The AdBlue filler and the diesel filler: telling them apart Check these before pouring, on a forecourt in East Town or a drive over in Salmonhutch. Seconds, that's all. - The cap. The AdBlue cap is often blue, or marked "AdBlue". The diesel cap normally is not. Read it rather than going by where it sits. - The size. On many cars the AdBlue filler neck is the smaller of the two. - Lift the filler flap and check for a label — plenty of cars mark which goes in each filler just there. - The handbook. If your filler isn't by your diesel cap, it's in your boot or under the bonnet, and the handbook says which. - The person who drove the vehicle last. On a hire or company car picked up from somewhere like the car park outside Crediton, ask before you leave, not when the light comes on. ## Topping up AdBlue without it reaching the diesel tank A routine for the day the light comes on, wherever in Devon that is. - Park and switch off. Not on a slope, not with the engine running, and not in a rush on the side of Old Tiverton Road. - Daft as it sounds, saying "AdBlue" aloud while you unscrew the cap works — once you've found the filler and read it. - If both sit under one flap, check your diesel cap is still closed before you lift the bottle — then leave the car on. - Using the bottle's own spout, pour slowly — and stop when it's full or the bottle is empty. - Close the cap, then check once more — making sure your diesel cap stayed closed throughout. Only then, start the car. Stop there if you find, at stage two or three, that you have already poured into the diesel side. Don't go on to stage five. ## Put AdBlue in your diesel tank around East Town already? What follows is a short order of things, beginning with no starting the motor. Do not switch your ignition on; on many diesels that alone runs the fuel pump. Filling up with diesel will not dilute it: instead, AdBlue drops to the base of the tank, just where fuel is taken from. Ask the staff to help push the car clear of the pump if you are on a forecourt — the Green Earth Biodiesel, the Shell or anywhere else. At home in East Town? Then your car stays where it is. Stop as soon as it is safe and switch off, if the motor has already run. On the M5, under 10 miles from East Town, that means the next exit. About how far did it go? Crossing East Town is smaller work than a run of under 10 miles towards Exeter, so say. ## Our arrival in East Town, and what occurs next Our technicians come to the car wherever it has stopped, whether that is outside Hayward's Primary School, near General Buller's Grave or on your own drive. The answers decide the work and our price, so our engineers ask what went in, roughly how much, and if it's run. During the phone call itself, you are told our price — before dispatch. Emptying that tank comes next, followed by a full flush of your system. More than with petrol, it matters with AdBlue: the crystals form, certain metals are attacked, and none of it washes away unaided, no matter how long it sits. After the fuel filter has been cleaned — or replaced, where required — fresh diesel is added, and finally your car gets tested. After that our engineers fire it up and make sure it runs correctly before we leave. If the engine hasn't run, the majority of jobs take about half an hour once we're there, using pumps that are safe on a busy forecourt and quiet enough to use outside a house after dark. Your insurer will ask for an engineer's report and your VAT invoice, and both are yours at the end. Payment is on the day, with no money upfront. It is worth checking your insurance while we travel to you: misfuelling cover is included with plenty of policies. ## About East Town, for a moment East Town is a suburban area located inland in Devon, approximately 7 miles from Exeter and 160 miles from London, with a mix of semi-detached housing.

Give a postcode that starts EX17 1, and our van arrives quickest. No need to shift the car. Wherever it sits — beside Crediton Parish Church, on a layby en route to Newcombe's Meadow, on a drive — that's where it is emptied. Tricky to pin down, like the back of Crediton Arts Centre? By a border? Asking beats assuming, so phone. ## The short version for East Town drivers Before you pour, read the cap.
