Chrysler 300M TSB #070100
Hi, I have the same symptom on my 2000 300M. I had Chrysler perform the TSB for it (#070100) but the noise is still there. Any suggestions what else this could be? I've been to two mechs now and neither one can cure the problem.
TSB070100 - Cold-engine growl. The engines in some 1998-2000 Concorde, Intrepid, LHS and 300M models may emit an off-idle speed growling sound, which comes from the drive belts following a cold-engine start, while the transmission is in Drive or Reverse. The noise usually is heard when the engine revs between 1000 and 1300 rpm. The cure involves raising the tension on the generator/power steering drive belt.

I have a 2000 Chrysler LHS with the same deal. I took it in to have the tensioner tightened according to the bulletin, and it seemed that at first the noise went away. Well, it's back now and I'm thinking that the tensioner is just going bad. Have you had any luck fixing it since your last post?

The mechanics at my dealership are guessing, throwing parts and labor at it, when it is clear that they really do not know what the problem is. So far I have had a new servo installed and a new wheel speed sensor. While the parts and labor have totaled over $300, the problem has not been fixed.
Has anyone out there had a similar problem and had it successfully repaired? If so, what turned out to be the real problem?
Thanks
edit: If you try this repair there is one thing to note: When putting the switch back together, the plunger must be held about half way in. Take a look at it, you'll see why.
