Hey guys, so my car wouldn't start a few weeks ago and it got towed to the dealer. The service advisor said that it was a bad battery. My 2010 E92M has approx. 35K miles on the odometer. They said the battery failed because I spilled some 'yellow' unknown liquid in the battery department. This cause the battery to short and fail. They would not cover it under warranty.
I have attached some pics. Please give me your thought about what really happened.
I know I did not spill anything in the battery compartment. Any idea what that yellow stuff is?
