Hunting on Idle and Various Error Codes - centurionduck - 3:rd-Jul-2021

Hi all, my Astra J is hunting on idle and has various error codes being displayed. I thought the hunting might be the SCV but the fuel consumption at idle doesn't match the other posts on this issue:

Astra J Hunting

I have the SVS error message and these are the codes that were pulled:

P037E - Glow Plug Module Feedback Low Voltage
B1517 - Battery Voltage
U0164 - Lost Communication With HVAC

Then I have a list of Door, wiper, light and washer codes:

B3101 - Keyless entry data link circuit
B3109 - Keyless entry transmitter battery
B3125 (x3) - Door lock Unlock Short Circuit 
B3938 - Fuel fill door actuator lock circuit
B3882 - Right tail lamp circuit open
B370B - Rear wiper control circuit open
B3873 (x2) - Washer relay circuit open and short

I am not currently having any issues opening/locking doors, using washers, wipers and lights. I'd like to get the cause of these fixed but I'm more worried about the top three and the hunting. 

Can anyone offer any advice and experience on what my issues might be and where I start fixing first? 

Thanks!

I would start by clearing all the codes as some might be old codes, then work with what you get after that
