You can get the Range Rover suspension fault max speed 30 mph for many reasons:

Reason 1: Problem with Calibration

You will need to perform a suspension calibration after changing any powertrain component.

Solution: Perform A Suspension Calibration

Performing a suspension calibration can help you fix the Range Rover suspension fault error. To perform a suspension calibration on your Range Rover, follow this short video: 

If your suspension system stops functioning your car may not move. You will then need to send an SOS signal for help. But your Range Rover may have limited SOS functionality. So, fix the suspension system as quickly as possible.

Reason 2: Problem with The EAS Compressor

Your suspension fault error can also be related to a faulty EAS compressor. In that case, the symptoms you’ll be facing are given below.

Symptom:

  1. You are getting a C1A13-64 error code on your OBD2 diagnostic tool.
  2. You have white powder blocking the silencer of the air suspension unit.
  3. Compressor runs continuously
  4. The car sags when parked. If your Range Rover lowers when parked, that is a different issue.
  5. Compressor will not turn on at all

Solution: Replace The EAS Compressor

Tools and materials needed:

  1. A socket wrench
  2. A screwdriver
  3. A pair of pliers
  4. 4 car stands
  5. A car jack

Working procedure: 

  1. Park the vehicle on a level surface.
  2. Ensure that the steering is pointing straight ahead.
  3. Raise the vehicle using the correct lifting points.
  4. Remove the compressor relay and discard it. Do not install a new relay until the compressor has been replaced.
  5. Remove the screws that hold the lower acoustic box cover in place. Once the screws are removed, release the tabs that hold the lower section of the acoustic box to the top section. Discard the old acoustic box.
  6. Carefully disconnect the main power and sensor connectors. Do not pull on the wires, as this could damage the compressor.
  7. Identify the compressor model. The compressor model is printed on a sticker on the compressor. You can also find the compressor model in your car’s owner’s manual.

Removal instructions for different compressors

  • Hitachi compressor:
  1. Depress the blue collar on the airline and pull it out.
  2. Remove the airline at the valve block.
  3. Discard the old pipework and replace it using the air fitting and J-shaped pipe supplied in the kit.
  4. Depress the metal collars on the inlet and exhaust pipes and pull the pipes out.
  5. Remove the compressor and mounting bracket by undoing the 3 mounting bolts as shown here:

  1. Discard the complete unit, including the bracket and mounting hardware.
  • AMK Gen 1 type compressor:
  1. Disconnect the airline from both the compressor and the valve block.
  2. Discard the old airline.
  3. Identify the inlet and exhaust pipes as shown here:

  1. Remove the inlet pipe by depressing the white tabs on the side of the pipe and pulling up.
  2. To remove the exhaust pipe, depress the collar ring down and pull the pipe from the housing.
  3. Undo the 3 mounting bolts that secure the compressor and mounting bracket to the vehicle.
  4. Remove the compressor and mounting bracket from the vehicle.
  5. Discard the complete unit, including the bracket and mounting hardware.
  6. Locate the old collet and air fitting at the end of the airline.
  7. Use a pair of pliers to grip the collet and pull it off the airline.
  8. Discard the old collet and air fitting.
  • AMK Gen 2 type compressor:
  1. Locate the airline connectors on the compressor and valve block.
  2. Disconnect the airline connectors by pressing the release buttons and pulling the airlines off.
  3. Discard the old airlines.
  4. Locate the inlet pipe and exhaust pipe.
  5. Remove the inlet pipe by undoing the air fitting.
  6. To remove the exhaust pipe, depress the collar ring down and pull the pipe from the housing.
  7. Locate the three mounting bolts that secure the compressor and mounting bracket to the vehicle.
  8. Use a socket wrench to loosen the three mounting bolts.
  9. Once the mounting bolts are loose, remove the compressor and mounting bracket from the vehicle.
  10. Discard the complete unit, including the bracket and mounting hardware.
  11. Locate the old collet and air fitting at the end of the airline.
  12. Use a pair of pliers to grip the collet and pull it off the airline.
  13. Discard the old collet and air fitting.

Pre-installation process:

Before the compressor is re-fitted to the vehicle, the original inlet and exhaust pipes need to be prepared. This is the same for all three compressor variants.

The pipes need to be trimmed to a universal length of 50mm as shown here:

This is to ensure that the push-fit connectors are able to grip and hold onto the pipe work.

  1. Fit the new air fitting to the airline. Make sure that there is 2-3mm of airline coming out from the bottom of the collet as shown here:

This ensures that the collet bites into the airline and reduces the risk of the airline being blown out from the compressor when under pressure/operation.

  1. Once the compressor is completely refitted, lower the vehicle to the normal ride height. Keep the vehicle supported, do not fully lower the vehicle from the lift.
  2. Start the engine and allow it to idle for 2 minutes to allow the air pressure to build up.
  3. Select the raising function of the vehicle’s air suspension. Only fully lower the vehicle to the ground when it raises under its own power.
  4. Tighten all nuts and bolts to the manufacturer’s specifications. Check all air lines and components for leaks and adjust if necessary.
  5. Road-test the vehicle and recheck for air leaks and trouble codes. The air suspension may require recalibration and/or ride height adjustment. It is advised that a wheel alignment is carried out.

Your EAS compressor has now been replaced successfully.

An EAS compressor is similar to a differential. Both can break down with almost no warning. Just like a noisy compressor, a whining differential is a sign of a bad differential.

Reason 3: A Faulty Height Sensor

A faulty height sensor can also be the cause of the Range Rover suspension fault error.

Symptom:

  1. One side of the vehicle will be at a different height compared to the other side.
  2. Visual inspection shows damage to the sensor.

Solution:

To replace the ride height sensor, follow the steps mentioned in this video:

After replacing the height sensor your Range Rover suspension fault error should be fixed. It is better to replace the faulty height sensor before the suspension system gets damaged. Range Rover air suspension cost can be between $2,000 to $3,000.

Frequently Asked Questions (FAQs):

Is air suspension better than normal?

Yes, air suspension is better than normal suspension. This is because air suspensions provide you with better ride quality. Air suspensions generate less noise and vibration. They also have less wear and tear from rough driving. However, air suspensions can be more expensive and difficult to repair than normal suspensions. 

How long do air suspensions last?

Air suspensions last 6 to 10 years, or 90,000 km to 1,60,000 km. but how long your air suspension will last will depend on your driving habits. If you do off-roading, air suspension can be expected to last less. Air suspension can also fail due to exposure to moisture.

Does air suspension need maintenance?

Yes, air suspension does need maintenance. This includes draining condensation from the air tank and adding anti-freeze to the tank. You should also tighten the lock collars regularly. But in general, air suspension requires little maintenance.
