Gentlemen , 2009 535xi super cold today in MD and after a long rainy day I noticed a frozen Icicle leading to a frozen puddle on the concrete parking space drivers side a little behind the front drivers wheel ,I'm really thinking this is trapped rain water that froze up and that leads me to think its a clogged drain ,I don't think this is a result of a sunroof drain being clogged ? any thought on where any other drain that could be clogged be ?

 

There is six total drains . 3 per side . 2 for the cabin filter drains . Two front and two rear sunroof drains .
Sounds like your front cabin filter drains are frozen . But appears that they are working due to the puddle under the rear of the front tire , That is where the water exits from behind the front wheel from inside the well cover drain exit .

If you look under the hood by lower shock linkage .. You will see a plastic cover with holes in a line .. Pour some hot water in there ,, it should melt the ice inside the drain tube and exit just behind the front wheel ..

 

nice thank you for the insight I pulled her in the garage at about 1:30pm today when I get home ill check out what you advised , thank you again

 

 

I had a puddle in the same general area, which turned out to be a failed seal in the windshield washer pump.

 

Leak from windshield washer pump leakage results in water IN FORNT OF THE front left wheel.
Drains referenced in this thread drain the water BEHIND the front wheels.
