Roof Motor and Microswitch Faults
The electro-hydraulic hood relies on healthy microswitches, wiring, and drains. Water or switch failure can stop the roof mid-cycle.

- Run the hood fully multiple times
- Check the parcel shelf divider is present and sensed correctly
- Inspect the pump area and drains for moisture
Midland Gearbox Failure
Early non-S convertibles share the weak 5-speed Midland manual gearbox used in first-generation hatchbacks.
Gear whine, Difficulty selecting gears, Noise worsening once warm
- Confirm whether it is an early 5-speed car
- Test every gear under load and overrun
- Look for gearbox replacement paperwork
Power Steering Pump Failure
Like the hatch, the electro-hydraulic steering pump can overheat and fail, often after noisy operation has been ignored for months.
Whining at parking speeds, Heavy steering when hot, Burning smell near the pump area
- Listen after a full-lock manoeuvre
- Inspect for evidence of the revised cooling fan
- Check battery charging and voltage stability
