--- title: AdBlue in a Diesel Tank Corbriggs? Read This canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/corbriggs-derbyshire/ location: Corbriggs county: Derbyshire latitude: 53.208640 longitude: -1.387570 service: AdBlue in a Diesel Tank updated: 2026-10-02 --- # Why It Occurs and How to Avoid It: AdBlue in a Diesel Tank in Corbriggs AdBlue already in your diesel tank? In that case set this page aside for now, leave the ignition and engine off, and ring 0333 366 0103. Caught before the motor runs, it is usually a drain and a thorough flush, done where the car is around Corbriggs. The rest of this page covers why it happens and how to make sure it does not — useful if you are reading ahead of time. ## Two fillers, two tanks: AdBlue in a diesel motor Many modern diesels in Grassmoor, as well as Corbriggs, run on two liquids; the engine gets only the diesel. AdBlue's own tank holds it, and from there it goes to the exhaust, where spraying treats the gas. Each tank comes with one filler of its own. On a lot of cars the two sit side by side under the same flap; on others the AdBlue filler is in the boot or under the bonnet. Topping up your diesel side at the petrol pump goes on constantly. Seldom filled, AdBlue usually goes in from a bottle, tipped by someone who must stop and think what filler it needs. The error lives in that gap. ## Corbriggs: how AdBlue in the diesel tank happens Seldom is it carelessness: usually three things coincide. On a driveway off A617 before work, or in the car park outside Three Cottages on the way home: that is where the rushed top-up takes place. What is the reason for the rush? As AdBlue gets low the vehicle tells you, and once it's gone, limp mode follows. Then, your hand reaches for the cap it knew on the old motor — because a rental car, a new motor or a company car puts the fillers where your last one didn't. No part 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. The same few seconds decide it, in the middle of Corbriggs or out in Milehill. ## How to tell the AdBlue filler from the diesel one Before you tip anything, whether on a driveway in Calow Green or a forecourt in Corbriggs, check these. They take a few seconds. - Colour and lettering: an AdBlue cap is often blue, or says "AdBlue", where a diesel cap usually doesn't. Trust the cap, not where it sits. - Check the size: the smaller neck is, on many vehicles, the AdBlue one. - Check inside the fuel flap: many vehicles carry a label there showing which fuel goes where. - The handbook. If your filler is not by the diesel cap, it's in your boot or under the bonnet, and the handbook says which. - Collecting a hire or company car, say at the car park outside Chesterfield? Check with the person who drove the vehicle last before leaving, not when the light goes on. ## Topping up AdBlue without it reaching the diesel tank Wherever around Derbyshire the light comes on, here is a routine for that day. - Switch off once parked — level ground, motor stopped, and never rushed by Hassocky Lane at the roadside. - Daft as it sounds, saying "AdBlue" aloud while you unscrew the cap does the trick — after you have located your filler and read the cap. - The diesel cap stays on. When the two sit under a flap, confirm it is closed before lifting the bottle. - Using the bottle's own spout, tip slowly — and stop when it is full or the bottle is empty. - Before you start your car, close the cap and look a second time that the diesel cap never opened off. If at step two or three you find you have already poured into your diesel side, stop there. Stage five is off limits. ## Put AdBlue in the diesel tank around Corbriggs already? Then the order of things is short. Don't start your engine. The fuel pump runs on many diesels as soon as the ignition goes on — so keep it off. Do not top up with diesel to thin it: AdBlue doesn't mix with diesel, it sinks to the bottom of your tank, where the fuel is pulled from. Ask the attendants to help push the car away from the pump if you are at a forecourt — the the nearest petrol station, the BP or anywhere else. If you're on your own driveway around Corbriggs, leave it where it stands. If your motor has already run, stop as soon as it is safe then switch off. Corbriggs lies under 3 miles from the M1; on it, use the next junction. Mileage counts — a quick hop across Corbriggs makes a smaller job than heading under 15 miles to Sheffield — so tell us about how far it went. ## Our arrival in Corbriggs, and what occurs next Anywhere the car came to rest, whether by Temple Normanton Primary Academy, near The Parish Church of St James the Apostle or at home, our van comes to it. Those answers settle this work and our quote, and so our technicians ask what got in, roughly how much, and whether it has run. No one heads out before you've had the price by phone. Draining that tank comes next, then a thorough flush of your system. Unlike petrol, AdBlue leaves crystals and attacks certain fuel-system metals, and none of it washes away by itself. That is why it counts more. Testing comes last: before that, clean diesel is added, and the filter is cleaned or replaced if necessary. Before leaving, our engineers fire it up and confirm that it is running correctly. Unrun vehicles usually need a half-hour job from the moment we arrive. The kit is fine on a busy forecourt, and hushed enough for a driveway late at night. Payment happens on the day, not upfront, and you are given the documents your insurer wants: an engineer's report and a VAT invoice. Misfuelling cover is part of plenty of insurance policies — so use the wait to look at yours. ## About Corbriggs, for a moment Corbriggs is a small hamlet in Derbyshire, situated on the riverside at an elevation of 98 metres.
