Volvo “Suspension Service Required” Common Causes & Troubleshooting Tips

When the “Suspension Service Required” warning message appears on the dashboard of your Volvo, it means there is an issue with the air suspension system that requires attention. Ignoring this warning can lead to an uncomfortable driving experience and an increased risk of an accident, so diagnosing and addressing the problem as soon as possible is important.

What Does the Suspension Service Message Mean?

The suspension system is responsible for absorbing shocks in the road while driving, giving you a comfortable ride. When this fault message appears, your air suspension system is malfunctioning.

⚠️ Why You Should Fix It As Soon As Possible:

• Safety Risk – This error message will create an uncomfortable driving experience that may lead to an accident.
• Performance Issues – The unbalanced suspension height can make it harder to steer.
• Costly Repairs if Ignored – Ignoring the issue may lead to more damage to the suspension and will affect other components. It can cost between $500–$5000 to fix this issue at the mechanic, excluding towing service.

Common Causes

• Low Battery – A weak battery will affect all the vehicle’s electrical components. Visually check for any signs of leaks, bloating, corrosion, and damage to the negative and positive terminals on the battery. Use a battery tester to check the voltage, state of charge, and state of health. The result must be a good battery. Note: The battery is stored in the trunk in some Volvo models, like the Volvo XC90.
• Blown Fuse – Fuses are safety devices that protect the vehicle’s electrical components from short-circuiting. Check the fuse using a multimeter to confirm its condition. A good fuse may give you a reading of 5 ohms.
• Faulty Relay – Relays are safety devices that prevent electrical components from overheating or high-voltage fluctuations. Check the relay for any signs of burning, corrosion, or damage. Use a multimeter to check the terminals 85 and 86 of the relay. A good coil will give you a reading of about 50-200 ohms. Check the terminals 30 and 87. There must be no reading or “OL.” If terminals 85 and 86 are supplied with the 12V, it will magnetize the contact of terminals 30 to 87, which will give you a reading of 0 ohms.
• Faulty Wiring – Defective wiring may cause electrical loss and communication problems. Inspect for any signs of looseness, corrosion, burns, or damage to the wires, including the sockets.
• Broken Air Hose or Air Pipe – Air hoses or air pipes will break, either due to aging or rough driving conditions. Check for any signs of leaks, disconnected air connections, and cracked pipes or hoses.
• Defective Air Compressor – Air compressor pumps wear out over time due to aging and mechanical or electrical damage. A faulty pump will not deliver air to the air shock absorber, leading to the warning message. Check if the pump is making a sound while operating. The sound will tell you whether the pump is working or not.
• Faulty Height Level Sensor – A faulty or misaligned height level sensor may cause the system to malfunction. Clean the dirt on the sensor and check the position of the lever arm.
• Faulty Air Shock Absorber – The air shock absorber may fail because of leaks or an electrical circuit fault. Improper calibration may also cause the issue. Carefully check for any signs of damage on the component.

🛠️ Pro Tip: Use an OBD-II Scanner to check for error codes related to the issue.

Common Symptoms

• Suspension Warning Message or Malfunction Indicator Light On – If the system detects a fault in any component, it will send a warning message or activate the malfunction indicator light on the dashboard.
• Uneven body height or low body clearance – Air is the key requirement for the air suspension to operate. A faulty system will often cause the issue.
• Can’t adjust the body height level -The body height of the vehicle will not be adjusted if there is a fault in the system.

Troubleshooting

Before taking your car to a mechanic, try these DIY fixes:

1. Check Battery Health – Visually check for any signs of leaks, bloating, corrosion, and damage to the negative and positive terminals. Use a battery tester to check the voltage, state of charge, and state of health. The result must be a good battery. If the voltage is lower than 12.4 volts, the battery should be replaced or recharged.
   Note: Car batteries typically only last 3-5 years.
2. Inspect Wiring & Connections – Inspect for any signs of looseness, corrosion, burns, or damage to the wires, including the sockets.
3. Inspect Fuses – Look for damaged or melted fuses in your vehicle’s fuse box. This could be an indicator of an electrical issue in your car. Use a multimeter to confirm its condition. A good fuse may give you a reading of 0 ohms.
   ONLY REPLACE OLD FUSES WITH NEW ONES OF THE SAME AMPERAGE.
4. Use an OBD-II scanner – Read and clear error codes to see if the issue is temporary.
5. Reset the System – If the warning light/error message was caused by a glitch in the system, it can be cleared by disconnecting the battery for 30 minutes or using a scan tool.
