ive read all the opinions on using 'bmw' coolant. are there no other coolants that are compatible???

also, has anyone used any radiator stop-leak type products in their bmw?

as you can tell, i have a small leak that im going to be tracking down soon, coming from directly below the center of the engine near the cabin, directly below the fill area (havent looked too hard yet)

thanks for any assistance.
