Move your add action call to ‘wp_ajax_fhw_do_ajax_request’ to outside the enqueue scripts callback. admin-ajax.php requests do not try to enqueue scripts. Your add action call can execute on plugin load, it does not need to be in a callback.

As I understand, I should use this code like so

add_action( 'wp_enqueue_scripts', 'fhw_register_script' );
add_action( 'wp_ajax_fhw_do_ajax_request', 'fhw_do_ajax_request' );
function fhw_register_script() {
	wp_register_script( 'fhw_formular', plugins_url( '/js/formular.js', __FILE__ ), array( 'jquery' ) );
	
	wp_enqueue_script( 'fhw_formular' );
	
	wp_localize_script( 'fhw_formular', 'ajax_object',
            array( 'ajax_url' => admin_url( 'admin-ajax.php' ), 'we_value' => 1234 ) );
	wp_enqueue_script( 'fhw_formular' );
}

The 400 Bad Request error persists.

Alright, this is my code how I am calling it

jQuery(document).ready( function($) {
	
	$('input').bind("change", function(e) {
		onSelect();
	});
	
	
});

function onSelect() {
	var data = {
		'action': 'fhw_getTyp',
		'typ' : this.value
	};
	jQuery.post(ajax_object.ajax_url, data, function(response) {
		$(".ergebnis").html(response);
	});
};
