^I am referring to multiple 996TT's + my GT2, and all 986/996(if equipped with the upgraded m535 alarm, standard on TT), assuming each is equipped with the immobilizer/alarm then no one should see any variance, outside of the battery quality of course.
2-3 weeks should be(is for many) a non-issue.
Cheers,

Once I swapped my ignition switch my car was able to sit for much much longer with zero issues. I still trickle it when it sits for weeks and weeks though.

 

I work from home from time to time and yes, I take train to work. but You can always find a way to sneak out with 996 shopping, taking car out on the weekends

 

Madwhip where do you live besides in your trunk?
