Hello guys sorry this is my first post. I just bought my first Audi! I'm in love. My problem is the heater core is bypassed and I just noticed a little bit of coolant on the ground coming from in between the oil pan and trans pan. Does anyone have a coolant diagram or know what lines back there I should look for? Also my emergency brake light continuously flashes. I have check the brake fluid and it's fine and the only codes it's throwing are a evac and maf sensor. Please help and thank you for your time.
