Known issues by generation
Both the M6 and 635CSi (E24) share some common concerns that owners should be aware of. The S38B35 engine, known for its high performance, requires timing-chain and guide replacements between 100,000 to 150,000 miles to prevent chain rattle, a well-known symptom. Additionally, the 635CSi’s M30B35 engine faces typical head-gasket failures and cooling system issues. Owners should also ensure the individual throttle bodies on the S38B35 are properly synced and balanced for optimal drivability. Collectors should maintain records of service for these critical components to uphold the vehicle's value.
