Outdated postcodes are a known issue. Postcodes have not been updated since the last reimport 1.5 years ago.

The postcode display for the roads needs to be fixed in the OSM data. Looks like there is no postal code area with postcode 04316.

But there is an relation with the id 1301664 which has the information of the postal code 04316 surrounding this area. Is this not enough? What would be the way to tag it to be recognized by nominatim?

Thanks for the relation id. A postal_code area should indeed be enough. Nominatim did import the relation, see [http://nominatim.openstreetmap.org/details.php?osmtype=R&osmid=1301664 here], but it can neither be found nor used in addresses. I've reopened the bug.

It looks like the main issue is that the name only appears in the postcode column, it should be copied as a ref into the name column.

ref in the name column got lost on updates.

Fixed in [changeset:c2417dd/nominatim]

Note 1: I've manually reimported the relation 1301664 to check that the fix works but other relations with the same problem have not been changed. They will automatically getsorted out once the data is touched in OSM the next time.

Note 2: this does not fix the well-known issue with postcode centroids (e.g. http://nominatim.openstreetmap.org/details.php?place_id=98362166) not being updated. They still may cause glitches.
