Symptoms and warning signs

Recognizing the early signs of weakening power tailgate struts on your 2019 BMW X5 can help you address the issue before it becomes a major problem or a safety hazard. Keep an eye out for these common indicators:

• Tailgate opens slowly or not fully: The power assist seems diminished, and the tailgate might stop short of its usual open position, requiring manual assistance to fully extend.
• Tailgate struggles to close: You might notice the motor working harder than usual, or the tailgate requiring a manual push to fully latch, sometimes accompanied by a grinding or straining noise.
• Tailgate falls unexpectedly when open: This is a significant safety concern. The tailgate may not hold its position and could drop suddenly, posing a risk of injury or damage to cargo.
• Inconsistent operation: The tailgate might work fine sometimes but struggle at other times, especially in varying temperatures.
• Chirping, groaning, or grinding noises: Unusual sounds during opening or closing can indicate increased strain on the motor, failing strut components, or worn hinges.
• Error messages: The iDrive system or instrument cluster may display a warning message such as "Tailgate Malfunction" or "Power Tailgate Restricted."
• Tailgate doesn't latch properly: The mechanism might not fully engage, leading to a warning light on the dashboard indicating an open tailgate.

Verification: Confirming Weak Struts

Before undertaking any repairs, it's crucial to verify that the power tailgate struts are indeed the root cause of the problem. Here's how you can confirm the issue:

1. Visual Inspection: Carefully inspect the struts themselves. Look for any signs of hydraulic fluid leaks (oily residue) along the strut shaft or around the seals. Check for any physical damage, bends, or corrosion on the strut rods.
2. Manual Operation Test: With the power tailgate disabled (consult your owner's manual for how to do this or simply try to manually open/close it), try to manually lift and lower the tailgate. If the struts are weak, you'll notice significant resistance when trying to lift it, or it will feel excessively heavy and difficult to hold in place. A healthy strut should offer firm, consistent resistance throughout its travel.
3. Listen for Motor Sounds: Pay close attention to the sounds the tailgate motor makes during operation. If the motor sounds strained, whiny, or excessively loud, it could indicate that it's overcompensating for weak struts, or it might be failing itself. However, weak struts often put extra strain on the motor, so it's a secondary indicator.
4. Check for Fault Codes: While weak struts themselves typically don't trigger specific OBD-II fault codes, related issues within the tailgate's control module or motor can. Use an OBD-II scanner to check for any stored diagnostic trouble codes (DTCs) in the vehicle's body control module or tailgate module. While a code like D90D04 (communication error) might appear, it's often a symptom of the system struggling rather than a direct indicator of strut failure.
5. Compare to a Healthy X5: If possible, compare the feel and operation of your tailgate to another 2019 BMW X5 with a properly functioning power tailgate. This can provide a clear benchmark for what normal operation should feel like.

Common Causes of Weak Power Tailgate Struts

Several factors contribute to the weakening and eventual failure of power tailgate struts in your 2019 BMW X5:

• Age and Wear: Like any mechanical component, hydraulic struts have a finite lifespan. Over time, the internal seals can degrade, leading to fluid leaks and a loss of pressure, which reduces their ability to hold weight.
• Frequent Use: The more often the power tailgate is opened and closed, the faster the struts will wear out. High-volume use, such as for deliveries or large families, accelerates this process.
• Temperature Extremes: Both very cold and very hot temperatures can affect the performance and longevity of hydraulic struts. Extreme cold can make the fluid thicker and seals stiffer, while extreme heat can cause accelerated degradation of the fluid and seals.
• Contamination and Damage: Dirt, dust, and other environmental contaminants can get past the seals, scoring the strut rod and leading to leaks. Physical damage to the strut body or rod can also compromise its integrity.
• Weight Stress: Consistently placing heavy items on the tailgate while it's open, or manually forcing it open/closed against the power assist, can put undue stress on the struts, leading to premature failure.
• Manufacturing Defects (Less Common): While BMW is known for quality, occasional manufacturing defects in specific batches of parts can lead to earlier-than-expected failure. However, for a 2019 model, age-related wear is more probable.

Diagnosis: Pinpointing the Problem

Accurately diagnosing the problem is key to avoiding unnecessary repairs. While weak struts are common, it's important to rule out other components of the power tailgate system. Here’s a more detailed diagnostic approach:

1. Isolate the Struts: If your manual test (with power assist disabled) reveals the tailgate is excessively heavy or doesn't stay open, the struts are almost certainly the primary issue. If it feels relatively light but still struggles with power assist, the motor or control module might be at fault.
2. Inspect Wiring and Connectors: Check the wiring harnesses leading to the tailgate motor and struts (if they are integrated power struts) for any signs of fraying, corrosion, or loose connections. A loose connection can mimic a failing component.
3. Tailgate Motor Check: If the struts appear healthy, but the tailgate still struggles with power assist, listen closely to the motor. A complete lack of sound, a grinding noise, or a very weak hum could indicate a failing motor. Some advanced diagnostic tools can test motor functionality directly.
4. Control Module Scan: As mentioned, use an OBD-II scanner to pull any codes from the tailgate module. Specific codes can point to electrical faults, sensor issues, or communication problems within the system. For more detailed information on your specific model, refer to the BMW vehicle hub.
5. Hinge Inspection: While less common, worn or seized hinges can also impede tailgate movement. Check for excessive play or stiffness in the hinges.
