Frequently Asked Questions
Which specific R107 model variants does this manual cover?
All R107 chassis variants built between 1971 and 1981 are included: the 280SL (M110 inline-six), 350SL, 380SL (M116 V8), and 450SL (M117 V8). Both US-market emissions-equipped versions and European-spec models are covered across all trim levels and body configurations, including the removable hardtop-equipped roadsters.
Does the R107 share any components with other Mercedes models of the era?
Yes. The R107 shares its V8 engines and rear suspension architecture with the contemporary W116 S-Class sedan and the C107 SLC coupe. Procedures for the M116 and M117 V8 engines documented here are therefore applicable to related repair tasks on those platforms as well.
Are the Bosch fuel injection systems fully covered for diagnosis and repair?
Yes. Early 1971–1973 R107 models used the Bosch D-Jetronic electronic injection system, while later models transitioned to K-Jetronic continuous injection. Both systems are covered with full component testing procedures, fuel pressure specifications, injector service steps, and sensor diagnosis to help you troubleshoot driveability issues accurately.
