1995 Audi A6 Quattro Q&A
1995 Audi A6 Quattro Question: why wont car start?
With all of that, you should have it towed to an independent Audi mechanic (vs. a "stealership") who will do what should have been done a while ago. A vague "fluid" can be anything, and the check engine light is usually an emissions issue and shouldn't effect driving. Take the car to someone who knows this stuff! - painter33
