Here was my project today,,,Z4 front strut leaking,,,,we don’t see this to many times,,,,it was a rare one both front struts leaking at 63k,,,,,these EDC struts are not cheap over $1000 each. When replacing the front strut it’s a whole lot easier to remove the brake caliper and brake rotor then disconnect the steering arm and thrust arm,,,,,leave the lower arm on,,,,once you have it removed then you can easily remove the steering knuckle,,,,then you can compress the spring and then replace the strut,,,,no programming needed for the EDC struts.
