On descent through FL190; a distinct dirty sock odor was detected by both pilots. Oxygen masks donned. 7700 squawked and [advised] with ATC. Reason given for [advising]. Emergency equipment followed to gate; no external issues found. Normal shutdown checklist completed. Report filed by pilots. Confirmation of submission. Mechanic briefed. Mechanic informed me flight attendants reported to him the dirty sock odor was evident after gear retraction in ZZZ. I asked the mechanic for the AML back to update my write up. He refused stating he would advise the Maintenance Manager. He did not as evidenced by the narrative on [reporting website]. I followed up with the [point of contact] in Maintenance Control. He said he would accurately update my briefing in the comments section. He requested I refile my report and I did. He confirmed receipt. The On Duty pilot called to check on crew. ZZZ1 Director called me to check on crew also. ZZZ line mechanic inaccuracies in report narrative is an injustice to all parties involved and a negative aspect to safety in so far as correcting issues.
After a shallow descent was started; pulled for open descent to comply with STAR constraints; engines came to idle; and a strong 'dirty sock' smell was observed in the cockpit. The Captain and I agreed it was a fume event associated with atomized engine oil from our training lessons. We donned O2 masks; I was the Pilot Flying and took control of the Aircraft. Directed ECAM ACTION and the Captain performed the appropriate checklists while I flew the Aircraft and talked to ATC; and landed in ZZZ without any mishaps. Emergency vehicles followed us to the gate and boarded the aircraft and investigated the event. Suspected engine oil seal leaking allowing atomized oil to enter the aircraft pack system.
A330 flight crew reported a fume event during descent; advised ATC; and emergency vehicles followed the aircraft to the gate. Captain also experienced a communication issue with the mechanic regarding the logbook write up.
