Overview. New Bosch monovalves and genuine Bosch repair kits are no longer made. Most aftermarket rebuild kits are poor quality. The Klima BVX-1 is a new valve that restores steady heat and A/C control year-round.
Features
- Vehicle-specific, drop-in replacement: mounts to the original brackets, hoses and electrical connector
- Reliable at high engine RPM and in extreme temperatures, where Bosch valves stick or allow flow when shut
- Built with technology from late-model vehicles
Fitment
- 1981–83 240D with ACC III
- 1981–85 280CE, 300D, 300CD, 300TD with ACC III
- Other W123 models with ACC III
- Not 1985 300D/CD/TD with California emissions and trap oxidizer: order the BVX-CA instead
