Obvious I know BUT if you are using the car (as I am) when its bright but very cold, check your tyre pressures.
This is very important. Extreme cold can drop pressures into the mid teens.
As an aside from my earlier post.
I was promted by my low Tyre pressure warning on my Merc GLE. Checked all car tyres as follows
Merc GLE all down 5-6 lbs
Merc SL down 4-5 lbs
Morgan Plus 4 down 5 lbs.
