My code is the following and i got an error500 with your code. Did i forgot something to do i’m confused. No feedback from anyone if this solution worked or not?

function 3tmj_count_profile( $user_id = 0 ) {
	global $wpdb;

	if ( empty( $user_id ) )
		$user_id = bp_displayed_user_id();

	return $wpdb->get_var( "SELECT COUNT(ID) FROM $wpdb->posts WHERE post_author = $user_id AND post_type IN { 'wpcm_vehicle' }  AND post_status = 'publish'" );

}

function profile_tab_advertenties() {
    	global $bp;

	$count = 3tmj_count_profile();
	
	$class = ( 0 === $count ) ? 'no-count' : 'count';
	
	$name = sprintf( __( 'My Posts <span class="%s">%s</span>', 'buddypress-meets-wp-car-manager' ), esc_attr( $class ), number_format_i18n( $count ) );

	//$name = sprintf( __( 'Advertenties <span class="%s">%s</span>', 'buddypress-meets-wp-car-manager' ), esc_attr( $class ), number_format_i18n( $count ) );
	//$name = 'Advertenties <span>' . count_user_posts( bp_displayed_user_id(), array( 'wpcm_vehicle', 'post' ) ) . '</span>';

   	bp_core_new_nav_item( array( 
		'name' => $name,
		'slug' => __( 'advertenties', 'buddypress-meets-wp-car-manager' ), 
        	'screen_function' => 'advertenties_screen', 
        	'position' => 30,
	    	'parent_url'      => bp_displayed_user_domain()  . __( '/advertenties/', 'buddypress-meets-wp-car-manager' ) ,
	    	'parent_slug'     => $bp->profile->slug,
		'default_subnav_slug' => __( 'advertenties', 'buddypress-meets-wp-car-manager' ), 
    ) );
}
add_action( 'bp_setup_nav', 'profile_tab_advertenties', 10);

I’m also trying to do the same thing! Did you ever find the solution to make it work?
