New to VCDS and troubleshooting new/used T-reg

Hello All,

I recently bought a 07 V10 Touareg and got a VCDS dongle to go with it. I am currently trying to work out any bugs issues with the system and I need some help. Mainly, I am trying to get my A/C to work, however, I also have some concern that maybe my alternator needs replaced. Using the VCDS I identified that the rear batter was low. I put it on the charger and now it seems that the voltage from the dash is typically in the 14V range. I am trying to identify if the AC has any issues, or if it's something that needs reset. I have reset the DTCs and the second alarm scan is what happens after the DTC reset. I will also post Econ mode on and off to show the condenser system cycle. Any help is immensely appreciated.

I've also noticed that the voltage drops below 14, whenever the HVAC system is used. Any help/ideas on what is going on here? Do i need to post the scan in a message instead of as an attachment?

Did you try on the official VCDS forum?

Are you sure the AC is holding a charge?
