MYLR 2024 Small clanking sound from brake pedal when gas pedal is released when driving in the winter and brake as compensation feature is turned on and actual driven range is 145km on battery 80-15%

per title, I noticed that in the winter with temp around -10C regen braking is not working for about first 15min of the trip, and brake as compensate clanks.

is the clanking behavior normal? Tesla wants 105+tax to look into it?

and also is battery range of 145km on MYLR expected when charged to 80% and discharged to 15%. car is always parked outside, my trips are generally around 20 min one way. its kind of sad when 480km should be full range
