I have a couple of questions, so if you guys can help me answer them It would be of great help.

1) I was talking to a friend that told me to take the coolant line out of my throttle body because all it does is prevent the butterfly valve from sticking when it is freezing out side. This would stop the flow of hot coolant threw the throttle body, which would make the air coming in colder. Has anyone heard of this and if so have you done it?

2) Recently I noticed a pop sound coming from my passenger side front brake when I am slowing down and the car is just about to stop completely. The brakes work fine, but I was wondering if someone has the same problem and might know how to fix it.

Thanks

disconnecting the coolant hose from your throttle body is a common mod for race cars. on a street car it's a bad idea. in fact, it can actually be dangerous because on a cold night, you can get some nasty condensation in there. don't do it. it's not worth anything in terms of power, and it just messes up drivability.

not sure about the pop sound though...new to BMW brakes.

A good idea just to save you the heart ache if it is something small... before you take it to a shop....

Take a look at your lug nuts... make sure they are all there... I know that sounds horrible.. and easy.. but trust me... I've had it happen....

Next take the wheel off.... make sure the brakes are cool... or atleast give them an hour after driving to do this... just push and pull around... make sure everything is bolted down... secure... check your brake pads... ect...

Is this sound transfering it self into a vibration??? Can you feel it in your steering wheel?

I know these things sound stupid.. but its better to check it.. and see if it is something simple rather than wasting money on something you could have fixed your self....

Check and get back to us... Good Luck
