AdBlue in a Diesel Tank in Tylers Green: How It Happens and How to Avoid It
Keep the engine and ignition off then ring 0333 366 0103 now — reading can wait when AdBlue is already in the diesel tank. Caught before the motor runs, it is generally a drain and a thorough flush, done where the car is around Tylers Green. Nothing happened yet? Below, the rest of the page covers the why it occurs and the ways to prevent it altogether.
Two fillers, two tanks: AdBlue in a diesel vehicle
No single fluid but two: that is what many modern diesels near Tylers Green and Terriers carry, with diesel feeding the engine. AdBlue's own tank keeps it, and from there it is sent to your exhaust, and there a spray treats the gas.
Separate tanks, separate fillers. On a lot of cars the two sit side by side under the same flap; on others the AdBlue filler is in your boot or under the bonnet. Filling your diesel side at the petrol pump goes on constantly. A driver who has to stop and work out where it goes usually fills the AdBlue side, from a bottle, and much less regularly. That gap is where the slip lives.
How does AdBlue in your diesel tank occur in Tylers Green?
Three things tend to line up, and carelessness is seldom one of them.
To start with, the warning. Low AdBlue brings a warning from the car, and letting it run out means limp mode — so a rushed top-up, perhaps before work off The Greenway, perhaps at The Mayflower on the way home after work.
The old car's filler is where the hand reaches — yet a rental car, a new car or a company car keeps the fillers elsewhere. That's a second thing: an unfamiliar car.
No part stops 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 takes place in Penn or the middle of Tylers Green, it's the same few seconds.
The AdBlue filler and your diesel filler: telling them apart
Check these first, on a forecourt around Tylers Green or a drive over in Penn Bottom. A few seconds, that's all.
- Blue and marking: an AdBlue cap is regularly blue, or says "AdBlue", where a diesel cap normally doesn't. Trust the cap, not its position.
- Many motors fit AdBlue the smaller neck of the two.
- The flap. Look inside your fuel flap for a label. Many cars say there which fuel goes where.
- The handbook says where it is if the filler is not next to the diesel cap: your boot, or under the bonnet.
- Picking up a hire or company car, perhaps at the car park outside High Wycombe? Check with the person who drove it last before leaving, rather than once the light goes on.
Topping up AdBlue without it reaching your diesel tank
On the day the light appears — wherever it is around Buckinghamshire — a simple routine to use.
- Park and switch off. Not on a slope, not with the motor running, and not in a rush on the side of Kings Ride.
- Locate the AdBlue filler, check the cap, and say the name "AdBlue" aloud as you unscrew it. It seems daft. It works.
- If both sit under one flap, check the diesel cap is still closed before you lift the bottle — then leave the vehicle on.
- Tip slowly, using the bottle's own spout. Stop when it's full or when the bottle is empty.
- Close the cap and check once more. Make sure your diesel cap was never opened. Only then start your car.
Discover during the second or third stage that AdBlue went into the wrong tank? That's where you stop. Don't go on to step five.
Put AdBlue in the diesel tank around Tylers Green already?
Then the order of things is short. Do not start the motor. Do not switch the ignition on; on many diesels that alone runs the fuel pump. Do not top up with diesel to thin it: AdBlue doesn't mix with diesel, it sinks to the bottom of that tank, where the fuel is sucked from.
At a forecourt — Shell, Esso or another — the attendants will normally help roll the car away, if you ask. Your own driveway around Tylers Green is where it should stay.
Stop as soon as it is safe and switch off, if the motor has already run. On the M40, under 3 miles from Tylers Green, that means the next exit. Distance counts — a quick hop across Tylers Green makes a smaller job than driving under 25 miles towards St Albans — so say about how far it went.
Our arrival around Tylers Green, and what occurs next
Our van comes to the car anywhere it has come to rest — your own driveway, beside The Methodist Church, or outside Manor Farm Community Infant School. Both the work and the quote depend on three answers — what fluid, what amount, and whether it's run — so our technicians ask. On the call itself, you are told our price — ahead of anything else.
Next: draining, then a thorough flush of the entire system. Not like petrol, AdBlue forms crystals and attacks some fuel-system metals, and neither washes out by itself. Hence it matters more. Once the filter has been flushed — or replaced, if required — fresh diesel is added, and then your car gets tested. Your engine is started next and checked to confirm it runs properly, all before we go.
Most jobs are finished in about half an hour after we get there, as long as the engine has not run — and the pumps our engineers use are safe on a busy forecourt yet quiet after dark outside a house. Payment happens on the day, not upfront, and you are given the paperwork an insurer asks for: an engineer report and a VAT invoice. Before we get there, take a look at your policy; many carry cover for misfuelling.
