When it comes to maintaining your BMW 335i, understanding the serpentine belt’s role is crucial. This belt is responsible for driving multiple peripheral devices in your engine, such as the alternator, power steering pump, and air conditioning compressor. Over time, the serpentine belt can wear out due to heat, friction, and exposure to engine fluids. Regular inspection and timely replacement are essential to ensure your vehicle runs smoothly and efficiently.

Ignoring these warning signs can lead to a sudden belt failure, leaving you stranded and facing a more expensive repair bill.
