Fair warning, I have found local models and frontier models to be very bad at the specifics when it comes to cars.
Small differences like month and year model can impact oil capacity, oil weight and things like that, the details that matter quite a bit.
But I found frontier models couldn't even get things like what engine was in a 1994 Nissan Skyline, one of the more infamous and talked about cars on internet forums for decades, with dedicated fan databases that would have been scraped.
That means questions like "what air filter do I need for my 1994 Suzuki Swift?" are hit and miss.
I'm currently integrating one for simple diagnostic readouts to integrated small touchscreen. The main goal being a retro looking display that mainly dumps ODB data/monitors, but also reads maps data to show a "waypointer" a la crazy taxi. (This is proving difficult)
Respectfully, I don't think this is....real?
-I mean, getting the absolute basic bits like diag codes converted from the odb 2 data to some program w/ a graphic interface is about as far as people get, if they can get passed the power and power on/off conundrums.
-If you get that far, How in the lord's name did you manage to seemingly....MITM the vehicles cloud service (climate/locks/remote start) using raspian or whatever? IE; how are you able to establish a TLS connection (yeah, like that lingo?) from the raspberry to the manufacturer API? I think the manufacturer would be interested, as you have functionaley made another key to the car.
-A more important question....what purpose does this serve? IE; the cloud connection/controller is in the car. I can't imagine it's easier to connect to the rasp shell (is it on 24/7?) to connect to the car app to turn on the ac.
- I assume you have one of the "big boy" ones with more WAM. THat said.....are you implying by saying "the pie can actually run qwen" that you are running it locally? if so.....erm...I need reciepts. Cuz idk what that even means nowadays.
Maybe i'm just jaded because my "crazy, crazy taxi style waymarker + ODB2" monitor isn't progressing, but this is...fishy
Qwen 4B and 9B should be faster and better reasoning than Gemma 4 E4B. Other good options for that much RAM are Gemma 4 12b and 31b. Gemma 4 E4B would be better for native audio, but OP is using Whisper for STT so prob doesn't matter
You get a bluetooth device that plugs into the odb port, or a patch cord that you connect to your raspberry pi. There are fancier ones with more features, that can do more than just report signals like watch for certain signals or changes.

Looks like a ton of this is aspirational.
For your project -- do you really need the car's GPS positioning? Could go with a dedicated GPS antenna, like the freematics dongle
I guess it is only 3B active which helps a lot but is Gemma 4 E4B not more practical?
the Mermaid diagram doesn't even render.

Why does it need to be hooked up to the car for you to ask it which type of engine oil the manual recommends?
What is the point?
