The actuator alone costs €743 from BMW; with a clutch kit and shaft seal approximately €1,340. Used M3s with SMG often have neglected hydraulics — check the accumulator and oil level. Symptoms: Jerky gear changes, extended shift times, hesitant pull-away, SMG fault message, hydraulic oil puddle under the engine. from 80,000 km | High |
