Title: b5 s4 symphony radio code
Post by: dilly on June 25, 2019, 07:47:56 AM
so, i just got a b5 s4 6 speed and of course the radio is stuck in safe mode.
since the code i found in the manual does not work, i am assuming the previous owner swapped out the radio he had ie. double din or whatever to another used stock unit not knowing you need the security code.
i assume this because i found the power and rca cables for a subwoofer in the trunk already ran.
i just called Audi of Albany NY and the service manager told me since audi changed their ways, i cant simply provide the serial number anymore. i would have to go in do a recode on the radio with their scan tools to make a new code.

does anyone know of any way or chinese steal your car hack programs that can do this procedure?
im not paying the 1 hr 155$+tax fee he told me it would cost.

i haven't found much info on hacking the radio code

93c56 maybe, possibly labeled s220. read with a programmer.
can not quite remember but code is 0x00 address or very early in the address range.

16 bit hex or decimal, which ever makes more sense. i think it is decimal.

i am guessing i can't do it with a cable... most likely have to get a programmer and open up the radio correct?
