Failed window regulators can be a major pain, leaving your window stuck open or closed, or even causing the window to fall down into the door. Unfortunately, genuine window regulators can cost an arm and a leg and many other alternatives are built with questionable quality. Put your worries to rest and replace your failed regulator with a brand new regulator from Bav Auto for long regulator life and fantastic quality. From 1974 to 2019, Bavarian Autosport was one of the premier vendors for BMW and MINI auto parts. We are happy to preserve the Bav Auto legacy by continuing to carry their high-quality products into the future. All Bav Auto parts will remain unchanged in design and sourced from the same OEM suppliers to ensure long-lasting reliability.

After years of exposure to the sun and elements, the integrated rubber seal on your BMW cowl tends to split and crack. This compromised seal can allow water and dirt to pass below the cowl and into your vehicle's interior, leading to damage and corrosion of sensitive components. Replace your windshield cowl with this Bav Auto cowl to prevent any potential issues and keep your BMW looking new!
