I have a 95 E320 and there is an issue with my 7k old rotors (call it "warped" or not) they make a pulsating sound. My MB mechanic says my calipers are fine, but the lug nuts were too tight and he said it was the lug nuts being too tight.

My MB mechanic has over 30 years of experience so he appears to be an authority to me on the subject.

What else am I to think? Calipers are operating fine so I need to chagne teh rotors again and torque the lugs equally to the required spec.
