The battery goes flat in a few days of inactivity. I identified the source of the currant drain to the infotainment system (fuse 35). With the ignition key turned off there is still a drain of about half an amp, more than enough to deplete the battery in a few days. Any idea's what can be causing this? Just started happening about a year ago.

Tthe vehicle must sit for 30-45 minutes to ensure all modules go to sleep prior to testing , did you do this ?
Yes. In fact I did the test after charging the battery from flat.
