Hi all,

It's been a while since i've posted but i've kept an eye out on the forum and been enjoying the 8 in the meantime.

For about 2-3 months now, I've been suffering from a parasatic battery drain which means that if the car is left for 2 weeks without driving, it struggles to start. If left a week, i also notice it's down but a bit better.

Below is the last scan I did at the end of October which i was hoping might give a clue. I can't remember if i cleared the fault codes afterwards or not but i can do another scan later this week to check.

I haven't changed the battery and am reluctant to do so without eliminating the other potential causes first and wanted to check what methodology others go through to find out where a drain might be coming from.

For reference, the following are known to me:

- TPMS has been disabled
- Soft close driver handle stopped working a few years back
- Rain sensor replaced in March - i can clear codes to see if it re-appears
- Auxiliary parking heating has never worked
- Driver identification component protection has always had this

Your advice is greatly appreciated.

Oli
