Preventing AdBlue in a Diesel Tank in Walkley Bank: Why It Occurs
AdBlue already in your diesel tank? In that case put this page aside for now, keep the ignition and engine off, then ring 0333 366 0103. A drain and a full flush, carried out just where your car stands in Walkley Bank, is normally all it takes if caught before the engine runs. Not happened yet? Further down, the rest of the page covers the reasons it happens and the how to prevent it altogether.
AdBlue in a diesel car, and its separate tank
Plenty of newer diesels on the roads around Walkley Bank and Lower Walkley carry two liquids, not one. Diesel goes to the engine. AdBlue's own tank keeps it, and from there it is sent to the exhaust, and there a spray cleans the gas.
There's a filler for every tank. Other cars put the AdBlue filler in your boot or under the bonnet; a lot more have both side by side under one flap. The diesel side is fuelled at the petrol pump all the time. The AdBlue side is fuelled far less often, normally from a bottle, and normally by somebody who has to stop and think where it goes. That gap is where the mistake lives.
How does AdBlue in your diesel tank happen around Walkley Bank?
Seldom is it carelessness: usually three things line up.
Hurry follows from the warning. Your car warns you as AdBlue runs low, and a dry tank puts the vehicle into limp mode — so the top-up happens quickly, before work on a driveway off Welbeck Road, or heading home in the car park at The Anvil.
Unfamiliar vehicles are next, as well. Rentals, new vehicles and company cars put their fillers differently, and the hand reaches for the cap used on the old one.
No part stops the pour once it has started, because a bottle with a spout goes into a diesel filler as easily as an AdBlue one. The bottle fits. Malinbridge or the heart of Walkley Bank: it is the same few seconds either way.
Telling the AdBlue filler from your diesel filler
A few seconds is all the checks take — so check them before you tip anything, on a drive in Loxley Bottom or a forecourt around Walkley Bank.
- Colour and marking: an AdBlue cap is regularly blue, or says "AdBlue", where a diesel cap usually doesn't. Trust the cap, not where it sits.
- On plenty of cars, size gives it away: AdBlue gets the smaller filler neck.
- Look inside the fuel flap: many motors have a label there saying which fuel goes where.
- Cannot find it next to the diesel filler? In that case look beneath the bonnet or in your boot — the handbook says which.
- Check with the person who drove it last — before you leave, not when the light comes on — if you collect a hire or company car from somewhere like the car park at Sheffield.
How to top up without AdBlue in the diesel tank
The day the light comes on, anywhere in South Yorkshire, follow this routine.
- Not in a rush on the side of Racker Way, not on a slope, not with your engine running: park and switch off first.
- Say "AdBlue" out loud as you unscrew the cap, once finding the AdBlue filler and read it. Daft, yes, but it works.
- Leave the diesel cap on. If both sit under one flap, check your diesel cap is still closed before you lift the bottle.
- Stop once your tank is topped up or the bottle runs dry; until then, tip gently through its built-in spout.
- Only then, start the car: close the cap, check a second time, and make sure your diesel cap was never opened.
Find during the second or third step that the bottle went into the diesel filler? That is where you stop. Don't carry on to stage five.
AdBlue in the diesel tank already, in Walkley Bank?
The short order of things, starting with no starting the engine. On many diesels the ignition alone runs the fuel pump, and so do not switch the car on. AdBlue does not mix with diesel — it sinks to the bottom of that tank, where the fuel is sucked from — so do not top up with diesel to thin it.
The attendants at JET, Morrisons or another forecourt will usually help to push your car clear if you ask. Leave it where it is if you're on your own driveway around Walkley Bank.
Where the engine has been run by now, pull over safely then turn the car off. On the M1, under 5 miles from Walkley Bank, that means the next junction. Tell us roughly how far it went: a run towards Sheffield, under 3 miles away, is a bigger job than a short hop across Walkley Bank.
What happens when we get there around Walkley Bank
Outside Rivelin Primary School, near Millennium Green Worm or on your own driveway: wherever your car has stopped, our engineers come to it. Both the work and our quote depend on three answers — what fluid, which quantity, and whether it's run — so our technicians ask. The quote comes over the phone, before any van leaves.
Draining that tank comes next, followed by a thorough flush of the fuel 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 the flush matters more with AdBlue than with petrol. A test is last: before that, fresh diesel goes in, and the fuel filter is flushed or changed as needed. The motor is started next and tested to make sure it runs smoothly, all before our technicians leave.
Most jobs are done in roughly half an hour after our engineers get there, as long as your motor hasn't run — and the pumps our technicians use are safe on a busy forecourt yet quiet at night beside a house. Nothing upfront; you settle up that day. At the end, the VAT invoice and a report from the engineer are handed to you for your insurer. Before we get there, have a look at your policy; plenty carry cover for misfuelling.
