Parts for your 2020 Bmw X3-Gas struts

2020 BMW X3 gas struts — purpose, maintenance and replacement

Based on BMW technical sources, gas struts are used on the 2020 BMW X3 (G01). BMW’s Technical Information System (TIS) includes procedures for removing and replacing the bonnet (front lid) gas pressure spring and tailgate gas spring on the G01 X3, and the BMW ETK/parts catalogue lists gas springs for both locations. The owner’s manual outlines a powered tailgate, which operates in conjunction with support struts. So yes — gas struts are relevant and fitted to this model.

On a 2020 BMW X3, gas struts do the heavy lifting quietly and safely. Under the bonnet, they hold the panel up while work’s being done. At the rear, the tailgate’s electric drive works alongside gas-charged struts to control the lift and smooth the motion, so the gate opens consistently without a big shove, and doesn’t slam shut.

Over time, seals and nitrogen charge can fade. When that happens, the bonnet or tailgate may feel heavy, open more slowly (especially on cold mornings), or not stay up reliably. A light oil film on the strut shaft or a faint hiss can also be giveaway signs.

Servicing-wise, they’re low-maintenance but worth a quick look whenever the vehicle’s in for routine work:

• Inspect every 12 months or 20,000 km for smooth travel, secure mountings and any oil mist on the shaft.
• Keep the shafts clean, just wipe with a dry or slightly damp cloth. Don’t grease or spray silicone on them — that can damage the seals.
• Replace struts in pairs on the same opening (both bonnet or both tailgate sides) to maintain even support and alignment.
• Support the panel with a prop before removal, the remaining strut won’t safely hold the weight on its own.

Quality matters. OE-spec or reputable aftermarket struts matched to the X3’s build (including whether it has a powered tailgate) deliver the right force rating and ball-stud fittings. Fitment is typically straightforward: pop the retaining clips, swap the strut, then confirm the panel opens fully and latches correctly. After replacement, cycle the tailgate a few times (manual and powered if equipped) to check for smooth operation and even lift.

If the X3 lives outdoors or racks up big kilometres, plan on testing the struts more often. A fresh set restores that tidy, easy-open feel owners expect from a BMW.

FAQs

Does the 2020 BMW X3 have gas struts on both the bonnet and the tailgate?
Yes. The G01 X3 uses gas struts for the bonnet and support struts for the tailgate, including models with the powered tailgate where the electric actuator works alongside gas-charged supports.

How long do gas struts typically last on a 2020 X3?
Many last 5–8 years, but climate, usage, and exposure can shorten that. If the bonnet or tailgate feels heavy, opens sluggishly, or won’t stay up, they’re due for replacement.

Should gas struts be replaced in pairs?
Absolutely. Replacing both on the same opening keeps lift and damping even, protects hinges and mounts, and prevents a new strut from overworking against a tired one.
