Hatch strut

Hatch struts are a common issue in BMWs, particularly X3/X4 and X5/X6. The drive motors will typically fail on one side, overstressing the other, until that one fails too.

When replacing electric hatch struts, it is important to replace both (if both have drive motors in them) as if one has failed the other is likely compromised.

It is worth diagnosing your automatic tailgate issue properly, as the tailgate function modules are also a common issue—leaking tailgate/boot/roof seals can cause moisture build up in the wells, corroding the modules located in them.

Most BMWs are now equipped with automatic hatch struts that can be controlled by a key fob or a foot gesture under the rear bumper. These hatch struts use an internal drive motor that is controlled by the tailgate control unit.

All hatch struts have the ability to stop moving when you manually try to stop it from opening or closing, which is due to built-in sensors in the drive motor that monitor the amount of current (torque) it uses.

There can be multiple, non-exchangeable types of hatch strut within any given model generation.

The best way to determine fitment compatibility of a hatch strut is to match the BMW part numbers from the catalogue. This can be done by decoding your vehicle’s VIN in a BMW EPC (electronic part catalogue.)

If you don’t have access to an EPC, provide our team with your vehicle’s 17-digit VIN—and we’ll check our stock for a compatible match.

There is zero-to-low interchangeability of hatch struts between models.
