Hi All, Does anyone know if we need to replace the timing chain on 2011 X3 Xdrive35i (N55 engine)? AFAIK timing chain can last for years, not like timing belt, but I don't know whether it needs to be replaced or not. So far my X3 is just fine, it has 118k miles on it. Just want to know if we need to replace it, after how many miles? Thank you. Regards, Bayu
