engine software reflash

just wondering if anyone has had an engine software reflash on their diesel
i understand there has been several updates having to do with the regen cycle of the DPF to avoid cylinder wash and oil dilution among other things
mine is a 09 gl320

There are reflashes for specific problems. However, I wouldn't touch any of the factory coding on any of the x164 diesels. Only exception is scr module update to address faulty alarms related to adblue injection system.
