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. We trust these parts, accessories, and upgrades so confidently that we back every Bavarian Autosport branded component with a 2-year warranty.
