Disappointing Bose

The BOSE in my keeper is disappointing, compared to the standard unit in one of the others it lacks depth and base. Occasionally the O/S front channel fails with no output, but turn it up louder and it kicks in

There are no audio fault codes in VCDS, what should be my next steps be as the lack of decent audio is a little frustrating especially with the BOSE system in the car?!

I believe Concert II now but previously had a Tape HU in it that I swapped to see if it was that

Ah, most probably not... That sounds a good place to start, any ideas on where to find the coding?!

I think this is for a TT but will at least let you know what is involved...


All I could quickly see is in the A2 the middle digit of the code has to be a number 2 for Bose..

Pretty sure either someone will directly tell you or link to something.
