F32 is the Coupé launched in 2013; F33 is the folding-hardtop Convertible and F36 the hatchback Gran Coupé introduced in 2014. The 2017 facelift does not coincide with the engine replacements. Pages are shared where engine and output match; body-specific availability still matters.

Documented maintenance
CBS calculates deadlines from use; read distance and date under Vehicle information → Vehicle status → Service requirements. Oil, front and rear pads, brake fluid and vehicle check are separate items. This handbook does not set a universal oil mileage or a numeric brake-fluid interval here. The F32 handbook’s service table specifies oil, oil filter and air-conditioning microfilter at every oil service; spark plugs and air filter at every second oil service. Change the air filter sooner in dusty conditions. This table comes from the VI/13 handbook. For engines introduced later, confirm service counters and the VIN-specific plan before applying the same frequency.
Documented faults and recalls
ADAC notes springs or dampers requiring inspection and occasional oil leaks. Its diesel review also documents the EGR-cooler recall: an internal leak may cause a fire risk. Check affected engines, periods and completed work by VIN; this diesel recall does not automatically apply to petrol versions.
