hey i just bought a 2000 a6 quartto 2.8 tip with 238,000 today and while i was driving i lost low beams wipers and heater, just from that i would normally say a fuse or something, but I've never owned an audi or any non american cars, i work in an accessory integration shop, and work on cars all day and honestly have no clue where to start, any help or input would be greatly appreciated, i am honestly desperate right now because i just got the car 4 hours from posting this
