A damaged serpentine belt can affect several systems at the same time, including the alternator, power steering, and A/C. On a 2008 BMW 328i, the problem may also involve the tensioner, idler pulley, accessory pulleys, or oil contamination, so replacing only the belt is not always enough.
If you notice any of these signs, it is a good idea to have the system inspected:
- Squealing or chirping from the belt area
- Cracks, fraying, or visible belt damage
- Oil or coolant on the belt
- Battery or charging warning
- Sudden change in steering effort
- Belt moving off-center
- Grinding or pulley noise
- Repeated belt failure after a previous replacement
What should you do?
- Avoid driving if the belt is badly damaged, partly shredded, or has moved off a pulley
- Inspect the belt, tensioner, idler pulley, and accessory pulleys
- Check for oil or coolant leaks before installing a new belt
- Diagnose the cause if the belt has already failed more than once
- Replace only the parts that actually need replacement
