Tick! Tick! Serpentine Belt
Asked by Prynce Aug 18, 2016 at 03:48 AM about the 2000 BMW 5 Series 528i Sedan RWD
Question type: Maintenance & Repair
My serpentine belt was going bad and since I
changed it it's been making an annoying loud
ticking sound. I checked to see if anything was
jammed in it but it's completely clear of debris

Always change all idlers and the tensioner when servicing a serpentine belt @ 80,000 miles.
I'll bet Tom is right, usually it is the tensioner. Serpentine belts will generally last for 100,000+ miles if all the pulleys are in good condition.
