Re: 850 Turbo, low power
Thanks for the info. You are right, I'm in North Bay, ON and it was -23C
during the night before this happened. I will go over this with the local

mildly again this morning, but cleared after I drove about 2-3 miles. I
just hope that this is not a potential source for damage to the turbo or
