T5 Auto transmission gearbox advice

[Rebuild]

Sealed for life means no service till your warranty has run out
Mine gets a drain and refill and filter every 60-70K DIY

"So decided to get the gearbox scanned, updated the software and gearbox oil changed."

More on the oil change.
Was it a full service flush and filter, or just drain and refill(which only gets about half the fluid)?Was the sump taken off(necessary to do filter)?
Was it VW spec oil? G055025 or similar IIRC
