Hey guys I would like to see if anyone here knows of a reputable independent BMW shop in San Antonio, Texas. I currently took my car into the BMW of San Antonio dealership because 3 lights were going off on my dashboard (Service Engine, Passenger Restraint, Passenger Airbag). After of 3 days of the car being there the SA tells me my car needs the positive battery cable replaced ($3,020), the thermostat replaced ($430), and the seat mat sensor replaced ($1,400). I picked up my car because that sounded a little sketchy to me specially since i only have 80,000 miles on my 2005 BMW 545i. After a couple of hours of driving it the service engine light came back on and it said "Increased Emissions" this time. I turned my car off and once I came back to my car and turned it on it said low coolant level, so I checked underneath my car and sure enough the car was dripping coolant (which it hadn't done before). I opened my hood and sure enough there is coolant dripping out of what seems to be a connection at the very bottom on the coolant container. Any help?
