What Fails on the E46 SMG System?
Most SMG failures aren’t catastrophic transmission issues, rather they’re related to OEM hydraulic or electronic components that age out over time. Here is a list of some parts that usually fail:
- SMG Hydraulic Pump: Wears out, slow to prime
- Salmon Relay: Voltage drops, fails to power pump
- Pressure Accumulator: Loses pressure, shifts become delayed
- Gear Position Sensor: Incorrect readings, stuck in gear or no-start
- Solenoids: Fail or get clogged, block shift commands
