2015 F-Type V8 S Convertible, 11k miles.

-Crackles out of the speakers- This doesn't happen every day but more often then not I get crackles out of the speakers every 10-15 seconds, even when the stereo is off, even when the engine is not running but the electronics are on. If music is playing (usually bluetooth) it cuts out the song when it happens and sometimes drops bluetooth to my phone.

-Bluetooth connection drop- My phone is always mounted to the left side of my steering wheel on a MagSafe vent mount, some days I get no connection drops, other days it'll drop and reconnect or not reconnect.

- Bluetooth Call quality- I can hear others fine over the speaker but every call I've ever attempted top up, top down, at speed or stopped my callers say the call quality is awful, I assumed this was just the car but I've seen other threads where people say it's great. For reference I have an iPhone 12 Pro.

- About 20% of the time AFTER I start the car I get the "Smart Key not found" warning telling me to place it against that spot under the steering wheel, holding the key there usually does not fix it, I've put new battery's in both FOB's and had the same warning with both FOB's.

Open to any suggestions for diagnosing or troubleshooting, based on other threads I've read I feel like it may be a loose wire connection or fiber optic issue, maybe a combination of issues? If a suggestion is to check connections on the amp or something can someone also point me in the direction of where that is located? I've seen lots of post talking about stereo connections in difference places but no pictures or videos of how to access the connections.

 

Not much help to you - but I have the same BT phone quality issues on my 2017. I can hear the other people fine but they struggle to make out what I'm saying. Have had it looked at twice in annual service and they replaced a module and claim it's fine now but callers tell me otherwise

Unfortunately no idea the root cause...

 

Have you had the mic checked? That's an obvious place to start, I'd have thought.

 

@jjslat
I am going out on a limb here, but your 2015 may have a poor grounding node... one that connects to the audio control box and/or one of the key antennas (there are several antennas in your car to help determine if the key fob is close at hand).
These grounding nodes often have 5~10 ground wires running to them from various boxes or functions.
The grounding node is a way for Jaguar to make a good quality electrical connection the aluminum chassis without fear of corrosion.
But if the node has snapped off or is floating .. then it could cause such problems.
Look into the Jaguar PDF Manual, and they list where all of these nodes are. Many are below the carpet, which is a PITA to remove.

 

Forgive me if I should know this but where can I get a copy of the PDF manual? I'm assuming I'm looking for a shop manual not the normal manual.

It's a good thought. Given this one is still under full warranty I didn't explore and left it to dealer to diagnose. Although not found an issue. I know they reprogrammed the touch screen system and tested a few other ideas but not sure on mic
Any idea how to access it / diagnose it?
