Hey guys, I am a newbie here with a 2008 535xi auto. I used to own a 03 330ci prior to that. I was just wondering whether the sprint booster SBBM0002S will fit a 5 series auto. A Sprint booster rep said yes even though theyre a little different. Other retailers said no and that I need the SBBM0012S. Any experiences with SBBM0002S on a 5 series auto? The reason I am asking is because I can buy a SBBM0002S off of someone for $200 instead of paying $300.
