Known issues by generation
The E28 M5's S38B35 engine, derived from the M1 supercar, is known for requiring timing-chain and chain-guide replacement at 100,000 to 150,000 miles to prevent chain-rattle symptoms. Synchronizing the six individual throttle bodies is crucial for optimal drivability. Age-related issues, such as capacitor failure in the Bosch Motronic ECU, are common, necessitating a rebuild or upgrade. Documentation of all services, especially those addressing valve-cover gasket leaks and rust repairs, is critical for maintaining collector value.
