I love got a 2005 Audi A3 3door with a Bose sound system but I get a lot of engine noise even with the stereo turned off. I am going to try to replace the amp and my part no is 8p3 035 233 . I have found a replacement with part no 8p4 035 223. I know the replacement is from a 5 door . Will this cause any issue ?
