Hey everyone, I have a huge problem on my hands here! Any help will be MUCH appreciated. It's not with the m5, but it's with our audi s4, the 2000 edition. So the turbos have blown and we have an aftermarket warranty for 2k on it from ADVANTAGE. So the ONLY thing modified is the exhaust system. The car is sitting at the shop to get fixed, they send an adjuster in to look at the vehicle and deny the claim and void the warranty on the basis of the exhaust being modified...is this legal?!!! I mean if ANYTHING the exhaust causes less back pressure, having the turbos last longer. Also..isn't their a law stating that any bolt on product cannot void the warranty...and can only void that part from the warranty product....please help! I don't know what to do..I definitely plan on calling these people tomorrow. What are my options?? I can't believe their actually allowed to do this... To me it sounds like their always just looking for a reason to void the warranty. Once again thanks.
