--- title: Narborough: AdBlue in a Diesel Tank, Explained canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/narborough-leicestershire/ location: Narborough county: Leicestershire latitude: 52.573290 longitude: -1.207780 service: AdBlue in a Diesel Tank updated: 2026-10-12 --- # Avoiding AdBlue in a Diesel Tank in Narborough: Why It Occurs If AdBlue is already in your diesel tank, stop reading for a moment: leave your motor and your ignition off then ring 0333 366 0103. A drain plus a thorough flush, carried out right where the vehicle sits in Narborough, is normally what it needs when caught before your motor runs. Here before the event? Then what follows covers why it happens and what to stop it ever happening. ## Two fillers, two tanks: AdBlue in a diesel vehicle Diesel goes to the motor — but many current diesels seen round Narborough and Whetstone hold another liquid too. AdBlue's own tank keeps it, and from there it goes to your exhaust, where spraying cleans the gas. Every tank has one filler of its own. Many of motors have a single flap for both, whereas some move the AdBlue filler to the boot or under the bonnet. Diesel goes in on each forecourt visit, week in, week out. Far less often, the AdBlue side is filled — normally from a bottle, by a person working out where it goes. That gap is where the error lives. ## How AdBlue in your diesel tank happens around Narborough Three things tend to come together, and carelessness is rarely one of them. Hurry follows from the warning. The vehicle warns you as AdBlue runs low, and an empty tank puts the vehicle into limp mode — so the top-up gets done quickly, before work on a drive off Desford Road, or on the way home in the car park outside Narborough Arms. The old car's cap is where your hand goes — yet a hire car, a new vehicle or a company car keeps the fillers elsewhere. That's the second thing: a new motor. And the bottle fits. A bottle with a spout goes into a diesel filler as easily as an AdBlue one, so nothing stops the pour once it has started. The same few seconds settle it, in the middle of Narborough or out in Littlethorpe. ## Telling the AdBlue filler from your diesel filler Before you pour anything, whether on a drive in Huncote or a forecourt in Narborough, check these. They take a couple of seconds. - Check the cap instead of going by where it sits: AdBlue ones are often blue or marked "AdBlue", and diesel ones normally are not. - Check the size: the smaller filler neck is, on plenty of motors, the AdBlue one. - The flap. Look inside the fuel flap for a label. Many cars say there which fuel goes where. - In the boot or under the bonnet: that is where your filler sits if it's not by your diesel cap, and the handbook says 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 outside the nearest station. ## Keeping AdBlue out of your diesel tank when you top up When the light goes on, anywhere across Leicestershire, follow this routine. - Turn off once parked — level ground, motor off, and not in a rush by Forest Road on the verge. - Say "AdBlue" out loud as you unscrew the cap, once finding the AdBlue filler and reading it. Daft, perhaps, but it works. - The diesel cap stays on. Where the two share a flap, make sure it is closed before lifting the bottle. - Tip slowly, using the bottle's own spout. Stop when it is full or when the bottle is empty. - Close the cap and check a second time. Make sure the diesel cap was never opened. Only then start your car. Stop there if you find, at stage two or three, that you have already poured into the diesel side. Stage five stays out. ## AdBlue in your diesel tank already, in Narborough? Do not start the engine: that is how the short order of things begins. On many diesels the ignition alone runs the fuel pump, so do not switch it on. Thinning it with more diesel fails, because AdBlue settles to the base instead of blending — and that is where your fuel is drawn from. The attendants at the nearest petrol station, Pace or another forecourt will normally lend a hand to push the vehicle away when asked. Your own driveway around Narborough is the place it stays. If your motor has already run, stop as soon as it is safe then switch off. On the M1, under a mile from Narborough, that means the next exit. Mileage matters — a quick hop across Narborough is a smaller job than heading under 10 miles towards Leicester — so tell us about how far it went. ## What takes place when our engineers turn up around Narborough Wherever the vehicle came to rest, whether by Greystoke Primary School, beside Narborough Congregation Church or on your own drive, the van comes to it. Both the work and our price rest on three answers — which fluid, which quantity, and whether it has run — so we ask. No one sets off until you've had the quote over the phone. After that: draining, then a thorough flush of the entire system. AdBlue crystallises and is corrosive to some of the metals in a fuel system, so it doesn't wash out on its own — which is why that counts more with AdBlue than with petrol. Testing is at the end: before that, fresh diesel is added, and your filter is flushed or replaced if necessary. Before leaving, our technicians start it and confirm that it is running smoothly. If the motor hasn't run, most jobs take about half an hour once we're there, using pumps that are safe on a working forecourt and quiet enough to use outside a house at night. Your insurer will ask for the engineer's report and the VAT invoice, and you get both at the end. Payment is on the day, with no deposit. Wrong-fuel cover is part of many insurance policies — and so use the wait to look at yours. ## About Narborough and where it is Narborough is a village in Leicestershire, situated on the River Soar, with a mix of old and new housing, predominantly detached homes.
