Dear Mini Friends, I have a problem with my R56 Mini One EZ 2014. He has run the 98 Ps machine and has run 27000 km. For a few months at the cold start a metallic sound appears like a nailing. If the engine is warm nothing to hear… I immediately made myself smart and drove to BMW! 3 times I was already there and there was nothing found! Even a stuer chains test was done and nothing came out. The steering wheel is ok according to BMW. Oil level is natural h was always fine, is checked every 2 weeks. Thank you for your help Lg Bullcomander
