I have a 2002 A6 Quattro and it was running fine until today. It sat the last 2 weeks in the cold and today my husband attempted to take it to work. He didn't let it warm up and now it is leaking oil and blowing thick blue smoke. There is oil on the tips of the exhaust pipes. I need someone who might know what could have happened to it as I am having a baby soon and I desperatly need my car on the road! Any adivse would be GREAT!
