2017 BMW X3 gas-struts — what they do and when to replace them
Technical sources confirm gas-struts are fitted to the 2017 BMW X3 (F25) on both the tailgate and the bonnet. BMW’s official parts catalogue (ETK/RealOEM) lists “gas pressure springs” for the tailgate and engine hood on 2017 F25 models, and BMW TIS includes removal/installation procedures for these struts. Major OEM suppliers (e.g., Stabilus Lift-O-Mat) also catalogue direct-fit lift supports for the 2011–2017 X3 range.
On this X3, gas-struts counterbalance the weight of the tailgate and bonnet, making them easy to lift and preventing them from slamming shut. They also damp movement, so the tailgate opens smoothly and stays put at full height. On vehicles with a powered tailgate, the electric drive works alongside the gas-struts—if the struts weaken, the motor works harder and the tailgate may fail to open fully or drift down.
As part of servicing, it’s smart to give the gas-struts a quick once-over. Look for slow or uneven opening, the tailgate not holding height (especially in cold weather), oily residue on the strut body, binding, or a noticeable hiss and loss of resistance. There’s no fixed replacement interval—most last many years—but by the 5–10 year mark many originals are tired. Replace in pairs on the tailgate to keep lift and balance even, the bonnet can often be replaced singly, but pairs keep feel consistent.
Handy tips for replacement and care:
- Always support the tailgate/bonnet with a prop or a helper before removing a strut.
- Use a small flat screwdriver to lift the retaining clip, then pop the ball-joint off. Don’t fully remove clips from the new strut—just lift to release, then press on until it clicks.
- Install with the rod pointing down where applicable to keep the internal seal lubricated.
- Keep the chrome rod clean, don’t grease it. Wipe away dirt and road grime that can chew the seals.
- If the X3 has a powered tailgate, cycle it fully open and closed after fitment. Some vehicles may need a brief re-learn via the tailgate button to set the new open height.

Popular questions about 2017 BMW X3 gas-struts
How long do the gas-struts typically last on a 2017 X3?
Most owners see 5–10 years depending on climate and use. Heat, cold, and frequent cycling all play a part. If the tailgate won’t stay up or opens sluggishly, they’re due.
Should both tailgate struts be replaced together?
Yes—replacing in pairs keeps lift and balance even and reduces strain on a powered tailgate motor. For the bonnet, a single strut can be replaced, but many prefer pairs for consistent feel.
Why does the tailgate drop more in cold weather?
Gas pressure drops as temperatures fall, so weak struts show their age in winter first. If it sags in the cold, new struts will restore proper holding force year-round.
