Engine

1.6L Twin Spark Petrol

• Variable Valve Timing (VVT) Variator Failure
  • Description/Symptoms: A rattling noise upon cold start-up, especially noticeable in colder weather. This is due to the failure of the VVT variator, which controls the timing of the intake camshaft.
  • Solution: Replace the VVT variator and potentially the timing belt, as the variator’s condition can affect the belt’s lifespan.
  • Estimated Cost to Fix: $500 - $800+
  • Recalls: None Found
• Ignition Coil Failure
  • Description/Symptoms: Engine misfires, rough running, and a noticeable loss of power. The check engine light will likely illuminate. This is often due to individual ignition coil failure.
  • Solution: Identify the faulty ignition coil (using an OBD-II scanner) and replace it. It’s often recommended to replace all the coils at the same time, to prevent future issues.
  • Estimated Cost to Fix: $100 - $300+
  • Recalls: None Found

Transmission

5-Speed Manual

• Worn Synchros
  • Description/Symptoms: Difficulty shifting into certain gears, especially 2nd and 3rd, often accompanied by a grinding noise. This indicates worn synchromesh rings within the gearbox.
  • Solution: Overhaul or replace the gearbox. Synchro replacement can be a complex job, making a full gearbox replacement a more common solution.
  • Estimated Cost to Fix: $1,000 - $2,000+
  • Recalls: None Found

Selespeed Automated Manual

• Selespeed Actuator Failure
  • Description/Symptoms: Difficulty selecting gears, inability to shift, error messages on the dashboard related to the Selespeed system. The Selespeed system relies on a hydraulic actuator to control gear selection and clutch operation, and these actuators are prone to failure.
  • Solution: Replace the Selespeed actuator or attempt a rebuild (although rebuilds are often temporary fixes). The system may also require recalibration after replacement.
  • Estimated Cost to Fix: $800 - $1,500+
  • Recalls: None Found
• Hydraulic Pump Failure
  • Description/Symptoms: Slow gear changes, hesitation, or failure to select gears. The hydraulic pump provides the pressure necessary for the Selespeed system to operate, and it can wear out over time.
  • Solution: Replace the Selespeed hydraulic pump.
  • Estimated Cost to Fix: $500 - $1,000+
  • Recalls: None Found

Suspension

• Front Wishbone Bushings
  • Description/Symptoms: Knocking or creaking noises from the front suspension, particularly when going over bumps. Vague steering response. The front wishbone bushings are prone to wear.
  • Solution: Replace the front wishbone bushings. It is common practice to replace the entire wishbone arms, as the bushings are often integrated.
  • Estimated Cost to Fix: $300 - $600+
  • Recalls: None Found
• Rear Trailing Arm Bushings
  • Description/Symptoms: Rear end instability, particularly under braking or cornering. Excessive tire wear. The rear trailing arm bushings can degrade over time.
  • Solution: Replace the rear trailing arm bushings.
  • Estimated Cost to Fix: $200 - $400+
  • Recalls: None Found

Electrical

• Instrument Cluster Issues
  • Description/Symptoms: Intermittent or complete failure of the instrument cluster, including gauges and warning lights.
  • Solution: Repair or replace the instrument cluster. This may involve soldering or electronic component replacement.
  • Estimated Cost to Fix: $200 - $500+
  • Recalls: None Found
• Body Computer (BCM) Malfunctions
  • Description/Symptoms: Erratic behavior of various electrical systems, such as lights, wipers, or central locking.
  • Solution: Diagnose the BCM and attempt reprogramming or replacement.
  • Estimated Cost to Fix: $300 - $800+
  • Recalls: None Found

Exterior

• Rust
  • Description/Symptoms: Rust developing on the undercarriage, especially around the wheel arches, sills, and around the door handles.
  • Solution: Cut out and weld in new metal, repair the area, and prime/paint.
  • Estimated Cost to Fix: $300 - $1500+
  • Recalls: None Found

Interior

• Airbag Warning Light Issues
  • Description/Symptoms: Airbag warning light constantly illuminated on the dashboard. This can be caused by faulty airbag sensors, wiring issues under the seats, or a faulty airbag control module.
  • Solution: Diagnose the cause of the airbag warning light (using an OBD-II scanner capable of reading airbag codes) and repair or replace the faulty component. This may involve cleaning or replacing airbag connectors, or replacing the airbag control module.
  • Estimated Cost to Fix: $100 - $500+
  • Recalls: None Found
• Window Regulator Failure
  • Description/Symptoms: Window will not move up or down, or moves very slowly.
  • Solution: Replace the window regulator.
  • Estimated Cost to Fix: $200 - $400+
  • Recalls: None Found

Summary
