    The best course of action would be to remove the trim from that side and listen where exactly it's coming from. As you/or anyone else can do at this pont is guess, which will not be very productive.

    I had a very quiet clunking noise from the rear of the car, which sounded like a loose wire behind the trim touching the metal panels on rear-passenger side, but after some checking it turned out to be a loose bolt, which holds the rear silencer to the petrol tank's heat shield :w00t:

    Your best bet is to remove the trim and make sure everything is fixed tight, and no loose wiring/plugs - there are a few on that side of the car.

    I had this fellas is it a quiet clicking noise? sometimes goes on for ages and you can hear it stood at the back of the car. Mine did it sometimes when i started the car and was driving but also it would just start doing it any time when it was just sat there. I mainly noticed it alot when i turned engine off after a drive i'd get out and think what the f**k is that. Then after a week my alarm started going off during the night/day etc when i checked during the night after my alarm had gone off the car was ticking away i was half asleep thinking this is f**king weird lol. I searched everywhere numerous times and eventually found the problem. It was coming from my central locking pump/motor which is inside the left panel in the boot where the subwoofer is. I disconnected all the connections to it cleaned them and put them back on. Not heard the nouse since and my alarm, has gone back normal too.

    Cant be many things tbh, siren, central locking unit, subwoofer, changer are only things in that area, if the central locking has a leak it could be the pump running on, but sure you'll find when panel removed fully, common fault in that area is the siren where the internal rechargeable batteries split & soak the board in acid, thus new siren needed & audi realised this & updated it to better one, but not better sound.

    Pump, I suspect a leak of a loose pipe & its overrunning, take foam of & check connections, be careful not to snap the connecting ends of.
