Sorry in advance for the rookie Cobb questions.....
Just got an aftermarket battery installed in my 2007 335i after getting advice from the forums here.
All seems fine, but the tech must have touched something as my cluster fuse was blown post-battery install and had to be replaced. And now my 'SERVICE ENGINE SOON' light is on.
1. Any insight/advice on how a new aftermarket battery (or blown fuse) would cause this?
2. Can I use my Cobb AP to check to see what code is causing the light to be on?
3. And can I clear it with my Cobb?
4. Finally, should I 'register' the battery with the car? I heard advice both yea and nay....
