Had my exeo 2.0 TDI st 143 CVT multitronic 6 months and I love it. However I have heard horror stories about the CVT so when I noticed a metallic rattle under acceleration i began to worry took it to a CVT specialist and preyed. Gearbox is fine heatsheilds all in tacked engine mounts all good and they still couldn't find the rattle. It's on the drivers side either front or back foot well. CAN ANYONE HELP.
