I need to look to see if i can find my front right pdc sensor in my bumper, looks liek the previous owner popped it out, into the bumper.
My 35d started right up today in -6, early this morning after sitting overnight on the streets of nyc. Car ran smoother than when I start it at 30 degrees.... that's weird to me. I've got a misfire on cylinder 5 when I start it between 10 and 35 degrees, and it runs rough for a minute or two. But at -6 this morning it started up silky smooth! stupid regen ruined my gas mileage though, in addition to the cold.
