Merlin,

I realize that some people on this forum don't like to search for things and that they will stop looking as soon as they find a little bit of information that confirms their preexisting position or allows them to draw conclusions that are false.

For those people you are correct F29 doesn't exist and the rest of us are fortunate to have you define the world for us because we clearly can't think for ourselves.

You will recognize the people because they will insist that the LR2 3.2 can't possibly have a Vapor lock problem due to hot soaking even though Volvo had that exact problem with the same 3.2 and they recalled vehicles to fix the problem.

Merlin I don't think that you are one of the people that thinks this way.

But for those that do you can stop reading now F29 doesn't exist, it has never existed and whatever you dreamed up is the most plausible reason for the solution to the mystery.


For the rest of us

Back to the topic

The power draw is due to the Bluetooth Module or the Satellite radio module. The modules are always connected to power and they are told to shut down via a command over the fiber optic cable. If for some reason the module doesn't shut down then it will draw a small amount of power. Based on this post its approximately 3 watts. Which is enough of a power draw to drain the battery. The time needed to drain the battery will depend on how old the battery is and its storage capacity.


My recommendation is to leave F29 disconnected and drive your LR2 to confirm that your parasitic draw is gone. And then bypass the modules with a fiberoptic loop and disconnect their electrical connection and re install F29.

From this point forward we will need to refer to the fuse that you found as the FUSE THAT DOES NOT EXIST

This is necessary so that we don't anger certain people

I'm sure you know the type "They know the price of everything but the value of nothing"

Take care

Are you off your medication again today, Paul?




Next, the only Volvo recall that responded to a vapor lock issue was for 2001-2005 model cars. Check your dusty calendar and you will see that was long before the LR2 was introduced.

The effect of a damaged or malfunctioning purge valve is the same symptom, but not the same root cause (look those up on Google if it confuses you). A malfunctioning purge valve will cause a problem with engine starts because its job is to purge fuel vapor from the EVAP canister. Hence the vapor lock issue when it fails. That is why replacing the valve in my car fixed the problem without having to replace the fuel pump, which is what Recall 220 required dealers to do.

Now be a good boy, run along now.

 

FWIW, fuse F29 is shown in the manual for my 2008, there is a slot for it in the fuse block but it's not installed. I have an SE, not sure if HSE accessories might use F29?

Entirely plausible that somebody wired up that slot for an aftermarket accessory. Although in many cases it's easier to just add an inline fuse and tap whatever hot makes sense (battery hot or ignition switched as needed). Depends on how easy it is to access the backside of the fuse block.

Also possible that somebody did a lazy and connected an accessory which *should* be switched with the ignition instead to a battery hot, creating this kind of issue.

My trailer brake controller is hardwired direct to battery hot, but there's a good reason for that.

 

Merlin,

Here is what we know

1. Some LR2's did show a F29 in the passenger compartment diagram
Note: mine doesn't show it but that doesn't conclusively mean that I don't have the fuse it only means that my labeling does not show a fuse




2. Land Rover did release documentation showing the fuse but I don't have a copy of the document just a picture that someone else posted



3.The actual fuse F29 was found and a picture was taken


What conclusion can be drawn from this information

A. LR2 owners that have no knowledge of this forum have found the fuse F29 and they did so independently of anything written here

B. LAND ROVER did change the label for some LR2's (see above) which make it incredibly unlikely that this is a third party device that was added to the vehicle (let's see if the person that made that assertion will admit their mistake)

C. Some people over estimate their abilities (see the Dunning-Kruger effect)


If you look above you will see that someone on this forum posted some recall information from Volvo which only affects vehicles from before Volvo was making the 3.2 Si6 that is in our LR2.

I point this out because you seem like a rational person and I think you will understand what I am talking about.

Take care

Paul

 

Ah. Looks like LR used the F29 designation in both fuse boxes then.

I have an empty slot labelled F29 in the box under the hood.

The fuse box under my glovebox ends at F28. Entirely plausible to me that additional OEM inline fuses in that area could be labelled F29, F30, etc.
