So I've been seeing a lot of posts on aftermarket stuff added, because obviously that's what we do. But I'm wondering how far are your dealers letting you go without voiding your warranty? I wanted to put a new driveshaft in and my dealer out here in Germany said hell void my warranty if I do it. And I know wheels are okay, what else has very one done that hasn't voided their warranty. I have mine for 7 years/ 75k miles. Can not decided if I want to void it or not. She's still relatively new.....
