recommended battery? Optima rep, duralast or any others?? >>
The Optima is a poor choice, if you notice all the ridges in the casing of the battery. There have been lots of issues with cracks and leaking.
They don't have a Gold Series from DuraLast for the TT and you will need a Dremel to remove some plastic from the bottom of the battery to match the ridges for proper mounting.
When my OEM battery was failing it showed some syptoms of those who complain about Instrument Cluster Failure. After I replaced my battery that all went away that was 25k mi. ago.
