How to Identify Bentley Air Suspension Issues [Common Issues + Fix]

Bentley cars use air suspension to give a smooth ride and sharp handling. This system uses air bags instead of springs, controlled by a computer to adjust the car’s height and comfort.

In this post, you will learn how to spot problems with Bentley air suspension. You will see signs of leaks, hear noises that shouldn’t be there, and notice if the car sits unevenly or rides rough.

You will also get tips on checking the system and what steps to take if you find an issue.

Symptoms of Bentley Air Suspension Issues

1. Uneven Car Height

When one side of your Bentley sits lower than the other while parked, it’s a sign of air suspension trouble. This unevenness happens when air leaks from one of the air springs, causing that side to drop. It’s crucial to check for leaks or damage in the air springs to fix this issue.

2. Car Sits Low in the Morning

If your car sits lower than usual in the morning but rises to normal height after starting, it suggests a slow air leak in the suspension system. Overnight, the leak causes the car to lose height, which is noticeable in the morning. Finding and sealing the leak is essential for repair.

3. Rough Ride

A smooth ride is a signature of Bentley’s air suspension. If you start feeling every bump on the road, it could mean the air suspension isn’t working right. This rough ride happens when the air springs can’t maintain the right pressure, reducing their ability to absorb shocks.

4. Warning Lights

Your Bentley is smart enough to warn you about air suspension problems. If the dashboard shows a suspension warning light, it means the system has detected an issue that needs attention. It’s a call to check the suspension system for faults.

5. Strange Noises

Hearing strange noises, like hissing or groaning from the underside of your car, often points to air suspension issues. These sounds can indicate leaking air from the springs or problems with the compressor. Listening closely can help locate the source of the noise.

6. Compressor Overworking

The air compressor should only run when needed to adjust the car’s height. If you notice the compressor running too often or for too long, it might be struggling to maintain the air pressure due to leaks or a faulty compressor. This overworking can lead to compressor failure if not addressed.

7. Delayed Response to Height Adjustment

Bentley’s air suspension allows for height adjustments for different driving conditions. If you experience a delay in these adjustments or if the car doesn’t adjust at all, there’s likely an issue with the air supply system, including the compressor, valves, or electronic controls.

8. Increased Fuel Consumption

When the air suspension is failing, your Bentley might consume more fuel. This increased consumption happens because the car’s aerodynamics are affected when it can’t maintain the correct height, leading to higher resistance and, thus, more fuel use.

9. Difficulty Handling

Air suspension plays a big role in how your Bentley handles. If you notice the car is harder to steer or doesn’t feel as stable on the road, it could be due to failing air suspension components affecting the car’s balance and grip.

10. Visible Wear or Damage

Sometimes, the problem is visible. Checking the air springs and related components for any signs of wear, damage, or aging can reveal air suspension issues. Cracks, tears, or extensive wear on the air springs indicate it’s time for a replacement.

How to Care for Bentley Air Suspension

Caring for your Bentley air suspension helps keep your ride smooth and prevents big repair costs. Here are some tips to make sure your car’s air suspension stays in good shape.

Regular Checks

Make a habit of checking your car’s height. If you notice any side lower than the other or the whole car sitting low, it might signal a leak or issue with the air suspension. Early spotting of such signs can save you from larger problems down the road.

Listen for Noises

Keep an ear out for any unusual sounds like hissing or groaning when your car is moving or even when it’s parked. These sounds can be early warnings of air leaks or compressor issues.

Professional Inspections

Even if everything seems fine, getting your air suspension checked by a professional once a year is a good idea. They can spot things you might miss and ensure every part of the system works as it should.

Avoid Overloading

Your Bentley is built to handle a certain amount of weight. Overloading the car puts extra pressure on the air suspension system, leading to wear and tear. Stick to the recommended weight limits to keep the system running smoothly.

By following these simple steps, you can help extend the life of your Bentley’s air suspension system and enjoy a comfortable ride for years to come.

FAQ

FAQ: How to Identify Bentley Air Suspension Issues

1. What is the first sign of Bentley air suspension issues?
The first sign can be your car sitting unevenly when parked. If one side is lower than the other, it might mean there’s a leak in the air suspension system.

2. Why does my Bentley sit low in the morning?
If your car is lower in the morning but rises after starting, it suggests a slow air leak. The suspension loses air overnight, causing the car to drop.

3. What does it mean if my Bentley’s ride becomes rough?
A rough ride indicates the air suspension isn’t maintaining proper pressure. This affects its ability to absorb bumps, making the ride less smooth.

4. Can warning lights indicate air suspension problems?
Yes, if the suspension warning light on your dashboard turns on, it signals that the system has found a problem needing your attention.

5. How can I hear if there’s an air suspension issue?
Listen for unusual sounds like hissing or groaning from under the car. These noises can point to leaks or issues with the air suspension compressor.
