2016 T6 Bevel Box And Final Drive


New Member
Hi All,
I have a 2016 T6 Transporter with 4motion, just serviced the engine and transmission and was going to service the haldex, final drive and bevel box. to my surprise I could not find drain bungs for the diff or bevel box just ports to check levels. been told that these are fill for life and only change oil if there is a problem?
Is this the case? Im old school and this seems a bit strange to me.
