Hello

I´m burning my head trying to retrofit RKDS system on my PQ35 jetta

My first error was my basic gateway without extended can, I solved it buying an used one with extend can function.

My second error was buying a 5Q0907273B antenna ans now I´m trying to flash it using VCP with FL_3AA907273___0010.frf sw but i´m getting errors like "wrong key". I have no much experience with this stuff. I did several dashboard eeprom flash on bench and gateway uprade by VCP but this module is winning me. Do I need a security acces password or I missing something else?

For sure my third error are wheel sensors, but first I want to see communication between antenna and cluster (5C6920873 H04 SW0811)

thanks a lot!

Hey friend were you able to downgrade the 5Q0 to 3AA D or F version?

You have to use "change security algo" before flashing in case of VCP System or modify ODX yourself in case of ODIS or Idex
You can use X011 firmware too as it is better for most dashboards pq35 vehicles, but it's is not public firmware.
Try change algo first.
Contact pm if you need assistance with FL_3AA907273___X011 or other
