I think I actually heard the 280 SE lock up today with the AC on -- a first. The temp gauge was normal for once, too -- maybe the pin was stuck or something.
Noticable turbine noise, even over the bad exhaust noise from the cracked manifold. Need to do something about that someday.... have the new manifold but am too lazy to tear into it.
I'd learn to live with the sound, a new clutch isn't going to change the noise. Just the way a Benz is!
