If the convertible top on your E46 3 series or E64 6 series is making a “whining” sound and will not unlatch from the windshield, then you probably need to replace your latch motor gear. The original factory gear is made of plastic and is notorious for failing after prolonged use. Our replacement BMW convertible latch motor gear is made of high strength steel instead of plastic and will stand up to the most rigorous use.
