PCM4.0 Infotainment system
FEC / SWaP Codes
SWaP is short for SoftWare as a Product. This is a strategy to sell and protect optional features and functionality for Audi, Volkswagen, Seat, Skoda, and Porsche infotainment units as if it was an actual material product. Most likely it's cheaper to manufacture an infotainment headunit that is equipped with hardware supporting all features and the lock out these that were not play for, than to have separate hardware configurations designed for each variant of optional equipment. This method gives also chance to cross sell additional features later on.
Here's where the FEC comes in. It's short for Function Enabling Code, and this is exactly what it does. After buying such code for feature that you are interested in having, dealer is installing it in your cars infotainment headunit and from now on desired feature is available for you.

Hacking
In some cases hacking is the only way to enable some features in some cars. For example Porsche PCM4.0 was not available from factory with Android Auto support. Also there is no FEC for Performance Monitor if it was not enabled from the factory.
Hacking MIB2 is basically 3-step process:
- Access filesystem
- Replacing ifs-root.ifs with patched one
- Replacing FecContainer.fec file with custom one
Connection methods
There are several methods to access MIB2 filesystem. After establishing network connection you can telnet into the device and use log in using one of the MIB2 root passwords that matches your device.
USB to RJ45
By enabling Developer Mode and connecting UBS to Ethernet adapter. [3]
- D-Link DUB-E100 (0x2001, 0x3c05)
- D-Link DUB-E100 (0x2001, 0x1a02)
- SMSC9500 (0x0424, 0x9500)
- Germaneers LAN9514 (0x2721, 0xec00)
- Cinterion AH6A 3G (0x1e2d, 0x0055)
- Cinterion ALS1/ALS6 (0x1e2d, 0x0060)
Quadlock Rx/Tx
- Adapter GND to car GND
- Adapter RX to J5_TX
- Adapter TX to J5_RX [4]
WLAN
- Create access point with your phone (or any other device)
- Connect your MIB2 device to this access point
- MIB2 will get a local IP - connect to this IP using telnet on port 23
POI update
Custom update files that will inject additional custom hidden green menu screens with options to copy and replace system files. [5].
POI update file must be prepared with correct structure and checksums. [6][7]
autorun script
In Discover Pro firmware 388 it is possible to execute a script named autorun placed on USB stick [8]
Patching system and replacing FEC file
Audi MIB2 / HMI2
VW, Seat, Skoda, Porsche MIB2 [9]
- Connect with MIB2-PCM4 via UART
- Launch a serial connection - 115200, 8, N, 1
- Login with root / oaIQOqkW
- Download Root-IFS
- Unpack Root-IFS (if using downloaded image from PCM4)
- Patch out the FEC checks.
- Rebuild IFS image
- Create your new FEC file
- Load new files to head unit
- change adaptation values as needed
