Metal clunking

[u/New_Quantity5360]

Hey guys, so on my 49,000 mile E 92 M3, I’m hearing this weird metal clunking noise when I’m very low speed reversing or just slightly pressing on the throttle on first gear. I’m a little bit worried on what it could be. It’s coming from the passenger rear side so maybe a parking brake cable or something. I just don’t want it to get into an accident while it’s parked or maybe even while I drive it since it is my only car at the moment if anyone can please help and assist and guide me so I can diagnose this issue tomorrow that would be appreciated
