Hi Shin,

My independent mechanic and I met today for coffee. I explained your
symptoms. He suggests you check the ignition switch connector where the
harness meets the back of the ignition key assembly. He's seen the behavior
you describe on other MB's and says it's a $20 MB dealer part but, he
charges $200 with labor to do the repair.

Good luck,
Dick
