For testing purposes connected the external soundaktor and module. Terrible pictures but the module is connected to provision wiring behind the driver seat. The speaker is sitting on the floor behind the passenger seat.
Coded for the module with VCDS, then with ODIS-E flashed unlocked SQ5 3.0 TDI firmware (for Gen 2.5 units)
from here. No faults, output test works (super loud in the car, haha). So my coding, wiring, module and speaker are all good. I planned for this sometime ago so already had it configured in my driving profile data set. Checking measuring values of the module show it receiving/accepting driving profile settings properly but...
No sound while driving
. I suspect I've got the same issue I had with some of the unlocked firmwares I initially tried for the internal soundaktor. Which is the firmware I loaded is for a car with DSG
. I suspect something in the phone where is looking for information from the DSG module which is not there on my 6MT.
From what I can tell the only generation 2.5 modules are from vehicles that only came with DSG so I might be out of luck. Fortunately I have a generation 2 module on its way from somewhere in Europe. Made it through customs yesterday so hopefully have it in by next week then get this going.
