The replacement of the harness did solve one problem I had been having - at idle the engine would sometimes stumble a bit. Almost like it was losing a cylinder for a split second. With the new harness installed the idle is a smooth as glass.
Thanks Tim, my 400E seems to be experiencing the same problems as your 400E did. I'll inspect the harness this weekend, any tips on inspection and installation, and I was wondering did MB help you on the harness cost?
enjoy your drive, timreid
