I've had the battery checked it's running fine

Thanks slot

I own a 2008 Audi A4 Avant which has an intermittent alarm problem while locked I've had a diagnostic performed and as the title suggests I have fault code 01330 comfort system Central control module voltage supply too low. is there a separate battery that powers the CCC and the alarm ? Can I simply replace this battery and therefore solve the low voltage problem ?

I've just bought 2008 Audi A4 S-Line Avant and under braking there's a small knocking sound the brakes are working fine I took it to a garage who advised that it may be the disc covers behind the disc . Has anyone had a similar problem if so please can you advise
