Just fitted a CONCERT 2 H/U to my 2001 A6,cannot get front speakers
working..the H/U is a BOSE,but my A6 is not.What code via VAG-COM should i
recode with?I have tried various combinations,it worked for a while,then
stopped.
any help please

Hi again,if i fit a CAN Bus simulator,will this fix the problem??As it
seems i lose the front speakers when i turn the ignition on & off.
thx again
