--- title: Explained: AdBlue in a Diesel Tank Borrowash canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/borrowash-derbyshire/ location: Borrowash county: Derbyshire latitude: 52.906260 longitude: -1.380460 service: AdBlue in a Diesel Tank updated: 2026-10-28 --- # Avoiding AdBlue in a Diesel Tank in Borrowash: Why It Happens If AdBlue is already in your diesel tank, stop reading for a moment: leave your engine and your ignition off and call 0333 366 0103. Normally, when your motor has not turned, it is emptied and thoroughly purged where the vehicle is around Borrowash. The remainder of this page explains why it occurs and how to make sure it does not — handy if you are reading before it has happened. ## Two fillers, two tanks: AdBlue in a diesel car Plenty of modern diesels around Elvaston, as well as Borrowash, run on two fluids; your motor gets just your diesel. Its own tank holds it, and from there it goes to the exhaust, where spraying cleans the gas. Separate tanks, separate fillers. On a lot of motors the two sit side by side under the same flap; on others the AdBlue filler is in the boot or under the bonnet. Diesel goes in on every filling station visit, again and again. Seldom filled, AdBlue usually goes in out of a bottle, poured by someone who has to stop and think what cap it needs. It is in that gap that the error happens. ## How AdBlue in the diesel tank occurs in Borrowash Carelessness seldom explains it. Instead is three things lining up together. On a driveway off Gordon Road before work, or in the car park outside The Nags Head heading home: that's where the rushed top-up takes place. What is the reason for the rush? As AdBlue gets low the car tells you, and if it's empty, limp mode kicks in. New-to-you motors are next, as well. Hire cars, new motors and company vehicles place their fillers differently, and the hand goes for the cap it used on the old one. A spouted bottle meets no resistance at a diesel filler no more than at an AdBlue one. So the tip, after begun, carries on. It's a few seconds, be it out in Shacklecross or bang in the centre of Borrowash. ## How to tell the AdBlue filler from the diesel one A couple of seconds is all the checks take — so run through them before you tip anything, on a driveway in Ambaston or a forecourt in Borrowash. - Read the cap instead of going by position: AdBlue caps are frequently blue or marked "AdBlue", and diesel ones usually aren't. - Many cars fit AdBlue the smaller filler of the two. - Open the filler flap and look for a label — many motors mark which belongs in each filler right there. - In your boot or under the bonnet: that is where the filler is if it is not by the diesel cap, and the handbook says which. - Ask the person who drove it last — before you leave, not when the light comes on — when you pick up a hire or company car from somewhere like the car park outside Spondon. ## Keeping AdBlue out of your diesel tank when you top up For the day the light comes on — wherever you are in Derbyshire — a simple routine to use. - Switch off once parked — level ground, motor stopped, and never in a rush by Station Road on the verge. - Daft as it sounds, saying "AdBlue" out loud while you unscrew the cap works — once you've found the filler and read it. - Both under a single flap? So make sure the lid on your diesel side stays shut ahead of lifting the bottle. - Pour slowly, using the bottle's own spout. Stop when it's full or when the bottle is empty. - Only after that, start the car: close the cap, check once more, and make sure your diesel cap was never opened. Stop there if you find, at step two or three, that you have already poured into the diesel side. Don't carry on to stage five. ## AdBlue in your diesel tank already, around Borrowash? The short order of things, starting with not starting the motor. Leave the ignition off as well, since on many diesels switching it on alone runs your fuel pump. Do not top up with diesel to dilute it: AdBlue doesn't mix with diesel, it sinks to the bottom of that tank, where your fuel is drawn from. Ask the staff to help push your car clear of the petrol pump if you are on a forecourt — the Shell, the Texaco or somewhere else. Leave it where it is if you're on your own driveway in Borrowash. If the engine has already run, stop as soon as it is safe and switch off. Borrowash sits under 5 miles from the M1; on it, take the next junction. About how far did it go? Crossing Borrowash is smaller work than a run of under 5 miles to Derby, and so say. ## Our arrival around Borrowash, and what occurs next Wherever the vehicle has stopped, be it outside Ashbrook Junior School, near Borrowash Methodist Church or on your own drive, the van travels to it. Which liquid was put in, the amount, and whether it ran: we ask since those replies decide both work and price. On the phone call itself, you hear our quote — ahead of dispatch. Then that tank is drained and the system flushed thoroughly. Unlike petrol, AdBlue leaves crystals and eats at certain fuel-system metals, and none of that clears out by itself. Hence it counts more. The filter cleaned or, where needed, swapped; clean diesel in; and then a check of the vehicle. Next our technicians fire it up and check it runs smoothly before we go. Most jobs are done in roughly half an hour after we get there, provided your engine has not run — and the pumps our engineers use are fine on a live forecourt and quiet at night beside a house. Payment happens on the day, not upfront, and you are given the paperwork an insurer wants: an engineer report and a VAT invoice. While we travel, have a look at your policy; plenty include cover for misfuelling. ## About Borrowash Borrowash is a village in Derbyshire, situated on the banks of the River Derwent at an elevation of 52 metres.
