Hello MB friends, with my OM642 (V6 3.0 280CDI) I can hear a clacker on the left 3 cylinders. When the bonnet is closed you can hear it relatively isolated on the left wheel box. An irregular noise. Was today at the ADAC test bench (free axle measurement, brake and spring test) in Stuttgart and there the technician said it sounded so mechanically / metallic that it could be a hydro-punch. With a friend I had thought that I could hear this noise too, but will listen more closely next time. Can another V6 diesel driver tell me something similar or problem solutions? MfG
