Hi,

please help!!

i have an audi a4 b8 - 59 plate.

due to the heat this summer my mmi system has decided to play up.

1st - the SD cards were not being read by the unit - would say loading the crash the system and keep switching on and off.
the radio decided to work now that seems to go off on the on board screen

i have checked on the vcds system and fault code 03029 has appeared up which states maybe a subwoofer open circuit.

i need help on this please as i dont know what this means as a new one is very expensive.
