0.6-litre engine and automated gearbox on the smart fortwo 450Known weak points
- Engine / equipment
- smart fortwo 450 (0.6 / 0.7 turbo and 0.8 cdi)
- Period mentioned
- 1998–2007
- Symptoms
- Jerky shifts (especially when warm or in traffic) or the gearbox refusing to shift; oil leaks from the head and valve cover; on early 0.6 engines, oil consumption and serious engine failures, sometimes before 100,000 km; rust on the frame, brake lines and exhaust.
- Possible cause described
- The electric clutch and shift actuator is the most frequent fault and needs a correct adaptation after any work. The early 599 cc engines were known for serious failures; they improved with the 0.7 in mid-2003.
- Check for the garage
- Work out whether the shifting fault is mechanical (clutch) or electronic (actuator, sensors) and always run the guided adaptation; measure oil consumption; check for rust.
- Cost cited in the source
- No verified estimate; ask the garage for a quote.A rough figure from the original database, not an up-to-date quote.
