Lower Padworth: How Does AdBlue End Up in a Diesel Tank, and How Do You Prevent It?
Stop reading for a moment when the diesel tank already has AdBlue in it: ignition off, motor off, then call 0333 366 0103. A drain and a thorough flush, done just where your vehicle sits around Lower Padworth, is normally what it takes when found before the engine runs. If you are reading before it has happened, the remainder of this page is about why it happens and how to make sure it does not.
Two fillers, two tanks: AdBlue in a diesel motor
Many modern diesels in Beenham, as well as Lower Padworth, carry on two fluids; the motor takes just the diesel. The exhaust, not your engine, is where AdBlue goes: sprayed into the fumes to clean them, from its own tank.
Separate tanks, different fillers. On a lot of vehicles the two sit side by side under the same flap; on others the AdBlue filler is in your boot or under the bonnet. The diesel side is filled at the pump all the time. Someone who has to stop and think where it goes usually tops up the AdBlue side, from a bottle, and much less commonly. That gap is where the slip lives.
Lower Padworth: how AdBlue in your diesel tank happens
It is rarely carelessness. Three things tend to line up.
To start with, the warning. Low AdBlue brings a message from your car, and letting it run dry leads to limp mode — hence a rushed top-up, perhaps before work off Back Lane, or at The Butt Inn on the way home after work.
The old car's cap is where your hand reaches — but a hire car, a new car or a company car keeps the fillers elsewhere. That is the second factor: a new vehicle.
No part halts the tip once it has started, because a bottle with a spout goes into a diesel filler as readily as an AdBlue one. The bottle fits. Whether it occurs in Aldermaston Wharf or the middle of Lower Padworth, it is the same few seconds.
The AdBlue filler and the diesel filler: telling them apart
Before you tip anything, whether on a drive in Padworth or a forecourt around Lower Padworth, check these. They take a couple of seconds.
- Position misleads; the cap doesn't. AdBlue caps are often blue or carry the name "AdBlue" — diesel ones usually don't.
- The size. On plenty of cars the AdBlue filler neck is the smaller of the two.
- A label inside the fuel flap frequently says which fuel goes where, on many vehicles. Check for it.
- 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.
- 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 Aldermaston.
How to top up without AdBlue in your diesel tank
On the day the light appears — anywhere it is around Berkshire — a routine to use.
- Park then switch off. Not on a slope, not with the engine running, and not in a rush on the side of Bath Road.
- Find the AdBlue filler, check the cap, and say the word "AdBlue" aloud while unscrewing it. It sounds daft. It works.
- The diesel cap stays on. Where both sit under a flap, make sure it is closed before lifting the bottle.
- Using the bottle's own spout, tip slowly — and stop when it's full or the bottle is empty.
- Only then, start your car: close the cap, check once more, and make sure your diesel cap was never opened.
Spot at stage two or three that it's already gone into your diesel side? So stop right there. Don't carry on to stage five.
AdBlue in the diesel tank already, around Lower Padworth?
Then the order of things is short. Don't start your engine. Do not switch your ignition on; on many diesels that alone runs the fuel pump. AdBlue does not mix with diesel — it sinks to the bottom of your tank, where the fuel is drawn from — so do not top up with diesel to thin it.
If you're at a forecourt, whether it's the Shell or the BP, ask the staff to help push the vehicle away from the petrol pump. At home in Lower Padworth? Then your car stays put.
Stop as soon as it is safe and switch off, if your engine has already run. Lower Padworth lies under 5 miles from the M4; there, use the first exit. Distance matters — a quick hop across Lower Padworth makes a smaller job than driving under 25 miles towards Oxford — so tell us roughly how far it went.
Our arrival around Lower Padworth, and what occurs next
Our technicians come to the car wherever it has stopped, whether that's outside Beenham Primary School, near Padworth Village Hall or on your own driveway. Our technicians ask what was put in, roughly how much, and if it has run, because the replies determine the work and our quote. Nobody sets off until you have heard our price over the phone.
Draining the tank comes next, then a thorough flush of your system. With AdBlue that matters more than with petrol: it crystallises and is corrosive to some of the metals in a fuel system, and so it does not wash out on its own. A test comes at the end: before that, clean diesel is added, and the fuel filter is cleaned or replaced as needed. Next our engineers start the car and check it runs properly before we go.
Using pumps safe on a busy forecourt and quiet enough to use outside a house at night, most jobs where your engine has not run need roughly half an hour after our engineers arrive. Paying happens on the day, not upfront, and you receive the documents your insurer asks for: an engineer's report and a VAT invoice. Plenty of insurance policies include misfuelling cover, so it's worth checking yours while we are on the way.
