It was very odd and it had not done it before. i took it in the next day but it had warmed up to -10c and wasn't doing it anymore. dealership put it on the hoist and checked everything out and took it for a test drive and couldn't duplicate the noise. tech guessed that it was a hanger underneath the car but as they couldn't duplicate it got a 'nothing wrong clean bill of health' and i gave the 335 back and left.

Same. Anything below -15C or so and the rear diff gets sluggish and noisy. Once it warms up its ok.
