Thanks a lot John for the reply.
I saved the value in a global array on my functions.php (or at least I think so..)

Any clue why on the archive-cars.php is working and in the category.php isn’t?

Here my functions.php file

**
 * Archive cars FILTER using pre get post?
 */

 // array of filters
 //NOTE: it's a sub field inside a field group so the meta query becomes => groupname_subfield
	$GLOBALS['my_query_filters'] = array(
	 'car_info_petrol'	=> 'carburante',
	 'car_info_gearshift'	=> 'cambio',
	 'car_info_brand'	=> 'marca'
	);

 function my_pre_get_posts( $query ) {

 	// do not modify queries in the admin
 	if( is_admin() ) {return $query;}

 	// only modify queries for 'cars' post type
 	if( isset($query->query_vars['post_type']) && $query->query_vars['post_type'] == 'cars' ) {

		// loop over filters
		foreach( $GLOBALS['my_query_filters'] as $key => $name ) {

			//allow the url to alter the query
	 		if( isset($_GET[$name]) ) {

				$meta_query[] = array(
					'key' => $key,
					'value' => $_GET[$name],
					'compare' => 'IN'
				);

				//Update the meta query args
				$query->set('meta_query', $meta_query);

	     }
		}

 	} //End of the if only on the post type cars

 	// return
 	return $query;

 }

 add_action('pre_get_posts', 'my_pre_get_posts');
