--- title: AdBlue in a Diesel Tank Brunshaw: Explained canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/brunshaw-lancashire/ location: Brunshaw county: Lancashire latitude: 53.785370 longitude: -2.215830 service: AdBlue in a Diesel Tank updated: 2026-10-01 --- # Preventing AdBlue in a Diesel Tank in Brunshaw: Why It Occurs Keep your motor and ignition off and call 0333 366 0103 first — reading can wait when AdBlue is already in your diesel tank. Usually, when your motor hasn't turned, it is emptied and thoroughly cleaned where the car sits around Brunshaw. Reading in advance? In that case the rest covers how it comes about and how to prevent it ever happening. ## AdBlue in a diesel motor, and its separate tank Many modern diesels in Burnley Wood, like those in Brunshaw, carry on two liquids; the engine takes just your diesel. Its own tank holds it, and from there it goes to the exhaust, and there spraying treats the fumes. There is a filler for every tank. Some cars keep the AdBlue filler in your boot or under the bonnet; plenty of others have the two together behind one flap. Topping up the diesel side at the petrol pump goes on all the time. Seldom topped up, AdBlue normally comes from a bottle, tipped by a driver who must stop and think what filler it needs. The mistake grows in that gap between the two. ## AdBlue in the diesel tank in Brunshaw: how it happens Carelessness rarely causes it. What does is three things lining up together. Hurry follows from the warning. Your car warns you as AdBlue runs low, and a dry tank sends it into limp mode — so the top-up happens quickly, before work on a drive off Slaidburn Avenue, or on the way home in the car park at The Thornton. The old car's cap is where your hand reaches — yet a hire car, a new motor or a company car keeps the fillers elsewhere. That is a second factor: an unfamiliar vehicle. Third, the bottle goes in: diesel filler or AdBlue one, it slides in just as easily, and once the pour starts, no part halts it. Pike Hill or the heart of Brunshaw: it is the same few seconds either way. ## The AdBlue filler and your diesel filler: telling them apart Before you pour anything, whether on a driveway in Worsthorne or a forecourt around Brunshaw, check these. They take a few seconds. - Read the cap instead of going by position: AdBlue caps are regularly blue or marked "AdBlue", and diesel ones usually are not. - The size. On many vehicles the AdBlue filler neck is the smaller of the two. - Check inside the fuel flap: plenty of motors have a label there showing which fuel goes where. - Can't see it beside your diesel filler? Then check beneath the bonnet or inside the boot — the owner's manual will say which. - Check with the person who drove it last — before you leave, not when the light comes on — if you pick up a hire or company car from somewhere like the car park at Burnley Central. ## How to top up without AdBlue in your diesel tank On the day the light comes on — anywhere you are around Lancashire — a routine to follow. - Not in a rush on the side of Belmont Grove, not on a slope, not with the motor running: park and switch off properly. - Locate the AdBlue filler, read the cap, and speak the name "AdBlue" aloud as unscrewing it. It sounds silly. It does the trick. - The diesel cap remains on. When both sit under a flap, make sure it's closed before lifting the bottle. - Stop when that tank fills or the bottle runs dry; until then, tip gently through the built-in spout. - Only after that, start your car: close the cap, check again, and make sure the diesel cap was never opened. If at step two or three you find you have already poured into the diesel side, stop there. Stage five is out. ## Put AdBlue in the diesel tank around Brunshaw already? Then the order of things is short. Do not start your engine. Do not switch the ignition on; on plenty of diesels that alone runs the fuel pump. Filling up with diesel won't weaken it: instead, AdBlue drops to the bottom of your tank, just where fuel is taken from. If you're at a forecourt, whether it's the Tesco or the Shell, ask the attendants to help roll the car away from the pump. At home around Brunshaw? So the vehicle stays where it is. If your engine has already run, stop as soon as it is safe and switch off. The next exit means the place to leave when you're on the M65, under 3 miles from Brunshaw. A short hop across Brunshaw is a smaller job than a run towards Bradford, under 25 miles away, so tell us roughly how far it went. ## Brunshaw: what happens when we get there Our technicians come to the vehicle wherever it has stopped, whether that's outside Burnley Brunshaw Primary School, near Brunshaw Methodist Church or on your own drive. We ask what went in, roughly how much, and whether it's run, since those replies determine the work and our quote. No one sets off before you've had the quote over the phone. Then that tank is emptied and the fuel system cleaned thoroughly. Unlike petrol, AdBlue forms crystals and attacks certain fuel-system metals, and none of it washes out by itself. Hence it matters more. Your filter is cleaned, or replaced where it needs to be; clean diesel goes in; and your car is tested. Before we go, we fire it up and make sure that it's running smoothly. If the engine hasn't run, most 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 at night. Paying happens on the day, not upfront, and you receive the documents an insurer asks for: an engineer's report and a VAT invoice. It is worth checking your insurance as the van travels to you: misfuelling cover comes with plenty of policies. ## About Brunshaw Brunshaw is a suburban area situated on the outskirts of Burnley, near the lakeside, with an elevation of around 149 metres.

Fastest of all: quote a BB10 4 postcode for the van. The car remains put. A drive, a lay-by on the way to Towneley Park 9 Hole Golf Course (Brunshaw Golf Course), a side street near Kingdom Hall of Jehova's Witnesses: our technicians drain it where it sits. Ring and ask rather than assuming if you're near a boundary, or somewhere hard to explain, like the back of Turf Moor. ## In short, for Brunshaw motorists First, the cap; after that, the tip.
