The 2008 Smart Fortwo convertible is a stylish and efficient city car, but like any vehicle, it can experience issues. One common problem reported by owners is with the convertible top. From electrical glitches to mechanical failures, a malfunctioning top can be a real headache. This comprehensive guide delves into the most common 2008 Smart Car Convertible Top Problems, providing you with the knowledge to diagnose and potentially fix the issue yourself.
Common Culprits Behind 2008 Smart Car Convertible Top Problems
Before diving into specific issues, it’s helpful to understand the key components involved in operating your convertible top:
- Hydraulic System: This system, comprising a pump, fluid lines, and cylinders, provides the power to raise and lower the top.
- Electric Motor: This powers the hydraulic pump.
- Limit Switches: These switches tell the system when the top is fully open or closed.
- Roof Control Module: The brain behind the operation, this module receives signals from the switches and controls the motor and hydraulic system accordingly.
- Fabric and Frame: The material of the top itself and the frame that supports it.
Troubleshooting Common 2008 Smart Car Convertible Top Problems
Let’s explore some common issues and how to address them:
1. Top Won’t Move At All
Possible Causes:
- Dead Battery: Always start with the basics. Ensure your battery is fully charged, as a weak battery may not provide enough power.
- Blown Fuse: Check the fuse box for any blown fuses related to the convertible top system.
- Faulty Roof Control Module: This module can malfunction, disrupting signals and preventing operation.
Troubleshooting Tips:
- Jumpstart your car to eliminate a dead battery as the culprit.
- Consult your owner’s manual to locate the correct fuse(s) for the convertible top.
- If a blown fuse is the issue, replace it with the appropriate amperage. If the new fuse blows immediately, there’s likely a short circuit requiring professional attention.
- Diagnosing a faulty control module often requires specialized diagnostic tools, so seeking professional help is recommended.

2. Top Moves Slowly or Stops Midway
Possible Causes:
- Low Hydraulic Fluid: Insufficient fluid can hinder the system’s performance.
- Hydraulic Fluid Leak: A leak in the lines or cylinders can lead to pressure loss and inconsistent operation.
- Air in the Hydraulic System: Air bubbles can disrupt the smooth flow of hydraulic fluid.
- Failing Hydraulic Pump or Motor: Wear and tear can weaken these components over time.
Troubleshooting Tips:
- Locate the hydraulic fluid reservoir and check the fluid level, adding more if needed (consult your owner’s manual for the correct fluid type).
- Inspect the hydraulic lines and cylinders for any visible leaks.
- Bleeding the hydraulic system can remove air bubbles. This procedure typically involves opening and closing the top multiple times while following specific instructions. However, it’s often best left to professionals.

3. Top Makes Grinding Noises
Possible Causes:
- Worn Gears: Gears within the motor or hydraulic pump can wear down over time, causing noise.
- Lack of Lubrication: Insufficient lubrication can result in metal-on-metal contact and grinding sounds.
Troubleshooting Tips:
- Pinpointing the source of the grinding noise can be challenging. If you suspect a lack of lubrication, consult your owner’s manual for recommended lubrication points and procedures.
- If the noise persists, professional diagnosis and repair are recommended.
4. Convertible Top Fabric Issues
Possible Causes:
- Rips or Tears: Sharp objects, accidents, or general wear can damage the fabric.
- Fading or Discoloration: Prolonged sun exposure can cause the fabric to fade.
- Mold or Mildew: Moisture buildup due to leaks or improper storage can lead to mold growth.
Troubleshooting Tips:
- Small rips or tears can sometimes be repaired with specialized fabric patches or adhesive.
