Parts for your 2018 Bmw X3-Gas struts

2018 BMW X3 gas struts — what they do and when to replace them

Based on technical sources — BMW’s official repair instructions (TIS) and the BMW parts catalogue (ETK/RealOEM) for the G01 platform — the 2018 BMW X3 is fitted with gas struts on both the bonnet and the tailgate. These sources list the “gas spring” components and outline factory procedures for removal and installation on the engine hood and the rear liftgate, so gas struts are definitely relevant to this model.

On a 2018 X3, gas struts counterbalance the weight of the bonnet and tailgate, making them easy to lift and steady to hold open. On vehicles with a powered tailgate, the struts still carry the load while the motor manages the motion, tired struts can make the motor strain and move unevenly. Fresh, correctly rated gas struts keep everything feeling light, safe, and OEM-correct.

They’re wear items. Expect service life to vary with climate and use — often 5–8 years or roughly 80,000–150,000 km. Cold winters, lots of short trips, or using the tailgate as a “lean-on” perch can shorten their lifespan.

Common signs it’s time to replace:

• Tailgate or bonnet won’t stay up, drops suddenly, or feels heavy
• Movement is jerky, slow, or worse in cold weather
• Visible oil film on the rod or a faint hiss/leak
• Powered tailgate struggles, stops part-way, or sounds like it’s labouring

Service tips for a 2018 BMW X3:

• Replace in pairs on the same opening to keep lift balanced and protect hinges and the power drive
• Keep the chrome rod clean and dry, don’t grease it — grit + grease = seal wear. A light silicone-safe wipe is fine
• Inspect ball studs and clips for wear or corrosion, renew any tired hardware
• Support the panel with a prop and have a second person on hand — struts carry real load
• Choose OE or quality aftermarket struts matched to the G01 X3, powered tailgates need the correct force rating

During routine servicing, a quick functional check is easy: open the bonnet and tailgate fully and let them sit for a minute. If they creep down or need an extra shove to start moving, note them for replacement. Fitting new struts restores that smooth BMW feel and prevents bruised heads, strained tailgate motors, and bent hinges.

Popular questions about 2018 BMW X3 gas struts

How long do the gas struts usually last on a 2018 X3?
Most owners see 5–8 years, but climate and usage matter. If the tailgate feels heavy in winter or the bonnet won’t hold at full open, they’re due. Testing during a service visit is the best way to catch them before they become a nuisance.

Can BMW X3 gas struts be re-gassed, or should they be replaced?
For the G01 X3, replacement is the standard approach. Re-gassing isn’t commonly supported by reputable suppliers and can be inconsistent. New, model-specific struts are inexpensive insurance and restore the correct force rating.

Are bonnet and tailgate struts the same part?
No — they’re different lengths and force ratings, and powered tailgate versions pair with specific hardware. Always order by VIN or verified part numbers from the BMW ETK/parts catalogue to ensure the right fit.
