They don't know what the fumes consisted of. Passenger cabin wasn't affected.
Same aircraft (D-AGWK) is said to have had a similar incident a couple of years before (ca 2008) with passengers and cabin crew getting nauseous after inhaling "burny" fumes.
Aircraft has been checked after both events, with no diagnosis. No fire or burning had been detected. According to the report, airline technicians think that fumes might have been caused by de-icing-fluid getting into air intake of one engine.
