My TT has an OPTIMA YELLOW TOP. Battery put in service date 12/2006 9 years on a battery in this heat...un freakin heard of! Very good value for down here.
Purchased a Red Top 35 today and it fits! I did have to take the bottom bracket and flip it so that the side of the battery facing the headlight [+ -] stayed secure.
I've always had sucess with the Deka ETX-20L in the DSMs, two EVOs, a Saturn race car, and now the TT (most of them running on E85 which is hard to start on cold winter mornings). As long as you discipline yourself to not run accessories with the engine off, they are a great option!
I bought the Yellow top today . fits the TT perfectly . and also made room for the breaker for the power cable for the Audio setup . the original battery was a little taller and wouldm't clear the battery coverery. so I was worried about mounting the breaker too far from the battery, now its all good.
Yes, 2009 Audi TT, $800 as part of my yearly service in LA. Complained to Service advisor about the labor, and he took 20% off the battery portion.
