Problems after msv2 upgrade

[Grappler]

After software and firmware upgrade to latest 1.33
When hooked up to rrs to explore and clear some faults- next morning flat battery in vehicle
Recharge battery and vehcle running but now audio controls on steering wheel are mixed up - mode increases volume

Im thinking the msv2 is not allowing the ecus to go to sleep and drained the battery
Any suggestion on what could be going on

Did you change any CCF settings? If not then perhaps the battery going flat caused a mix-up so suggest that you disconnect the battery for a minute.

No, didnt change any configs
Just scanned for faults then used clear faults from entire vehicle cmand
Yes i tried disconnecting the battery to reset the ecus but radio controls on wheel are still muddled
The battery is holding its charge after going flat following use of msv2
