New Member and New Defender Owner

Hello everyone -

My name is Scott and I just purchased a USA spec 2025 Defender with the 6 cylinder engine. I have driven a Benz for the last 30 years, the last 20 in a G-Wagen (which I still have). I also drive several classic British cars, also for more years than I care to mention. I have thousands of posts on the various MB boards (under Floobydust). I firmly believe in learning from a forum and giving back to the forum.

But with the introduction of the Defender to the US market a few years back, I can no longer justify the price of a G. Hence the switch.

I ordered a GAP tool before I even took delivery of the Defender and I have made many "adjustments" to customize it to suit my liking - auto stop/start, drive away locking, etc.

But the one thing that I want most to do is get rid of the audio system speed controlled volume. MB insisted on inflicting the pestilence on drivers, but I was able to disable it on every Benz I have owned. At fist, just disconnecting a wire, then using a Star System (which I have), a later, using a can blocker to suppress the speed signal to the head unit.

My understanding is that the Range Rover has the ability to shut this annoyance off, but so far, not so on the Defender.

Has anyone done this or know if it can be done? I am an electrical engineer and audiophile and this function makes me want to rip the steering wheel off. Any help, hints, etc. would be greatly appreciates.

That must be something recent. I have a 2024 Defender with Meridian sound and it doesn't have any speed control of the volume. Or it's not enabled. But I don't have a GAP tool. And as much as I would like to change the state of a few features i don't want to risk any of the warranty.

Thank you for your comments. I rented at 2024 for a week (the same spec as mine) and it too had this disease, although the adjustment curve was less aggressive than in my 2025.

As for warranty, the changes I have made are all things you can change normally; I just have it set to retain my preferences. I have no plans to enable features that might cause a warranty issue such as Dynamic Mode, etc. But I would absolutely not care about the warranty if I could rid my audio system of this pestilence.

I am hoping that one can enable a infotainment menu like the Range Rover or change a Mulitcan setting to kill the speed signal to the infotainment system. But I don't want to try things randomly as they can lead to real trouble. The kind you can't recover from.

Happy Saturday!

Could someone with a (preferably 2021) North American spec P400 (non plug-in) please upload their CCF? I'm trying to compare engine configurations to unlock.

Cheers!

Any Discovery owners following this thread who have tried Park Assist? Any luck?

Also anyone know if it is possible to add full Steering Assist, (not just Lane Keep Assist) to the cruise control.

Norland, I'm a fellow D5 owner, want to compare CCF activation notes?

Saw an old post about this in the thread but couldn't see an answer. Does anyone know a setting so that the rear lights are on all the time with DRL? Looking at older models there used to be a Scandinavian setup

Maybe just switch the sidelights on by turning the switch one notch towards you. The front U shaped DRL’s will be dimmed a bit but still perfectly effective. It would need to be done every time you wanted the rear sidelights on, which would annoy me.

That doesn't work for long, retains very quick to only DRL's. No Mud flaps for my 90.!

Thanks anyway, was just looking for a way they would be permanently on while driving without me having to do something every time. I'm sure there is a way. I'll keep looking.

hello,
I have a 2023 Defender P400e (PHEV) and just got an IID Gap Tool G4. Now I want to make some CCF changes. My question is: The car automatically turns off the ignition after a couple of minutes. Is there a risk it switches off while performing a CCF update? How do I prevent auto switch off while updating?

No. Once you've gone through 'Apply Changes' and confirmed all queries the IIDTool communicates with the vehicle and stops all unwanted activities. The vehicle will generally turn off and restart during the CCF programming procedure, but this is nothing to worry about. The IIDTool checks voltage and will not allow CCF programming when the charge level of the battery is no sufficient, but we can only test the voltage which indicates a current state of charge. If the battery is older, you can theoretically have a good momentary state of charge where the battery quickly collapses under load. This is why we recommend a battery maintainer be connected to the vehicle.

(But in all honesty, a good battery maintainer is several hundred $€GBP and puts out 25A+. Just make sure your battery is not on its last legs and don't play with the IIDTool without the motor running (OUTDOORS!!! Don't ask why I think it's necessary to mention) for a long period of time (again, don't ask). If you've just driven your Defender and the battery is in good shape, everything will be fine)

Thanks for your detailed response.
I think battery drainage is less of an issue with the PHEV because the battery is charged from the EV battery.
