Just fitted a 2nd hand concert radio to my A6,but unable to get sound from
the 2 front speakers,even after adjusting controls.The concert radio is
Bose compatible,would this affect this problem?Anyone have any
ideas,perhaps unit is faulty!!!

I'm guessing that your A6 is not equipped with Bose, and that the
Concert came from a vehicle which was so equipped?

The Bose system uses a remote amplifier for all speakers. The standard
install only uses a remote amplifier for the rear speakers.

The Concert H/U should be compatible, but you will need to alter the
settings (might possibly require VAG-COM) to turn the Bose setting off.

Okay, assuming it's the original Concert 2 (up to about summer 2001),
you need to change the coding as follows:

You should find that the coding is currently set to something like:
00017 (assuming CD changer and DIS - these will affect the last digit)

For a non-Bose install, the coding should be changed to something like:
00207.

In other words, the third digit should change from 0 -> 2
the fourth digit should change from 1 -> 0

HTH.

Peter, If you still pick up this post..Checked VAG_COM,the code shows
000201,but when i ran fault find,it showed a fault with front speakers,so
i cleared it.(This is with my original H/U,should i retry the Bose
H/U,without changing the 00201 code?

Err... that code is stored in the H/U itself. The new unit needs to be
coded up the same as the old one. It is that code which makes it a
'Bose' or 'non-Bose' unit. What code do you get with the new H/U
installed?

If the speaker fault went away after you cleared the fault code, I'd
guess that it was reporting it as an intermittent fault - probably
because the H/U had been powered up with the speakers not attached.
Again, this fault code is stored within the H/U.
