help! just purchased an S4 with 93k on...car is beautiful. maintenance was done however I just drive the car 1/2 mile, fired fine, parked turned it off. Then turned it back on and it sputtered, did not turn over, the lights flickered and never started. So I am wondering if its missing on one cylinder, has bad gas (very low gas when arrived) and / orsomething electrical. So I am not panicking but need to either get it towed to a audi guy (i have someone who works on audis). Also the guy that sold it is more than willing to work it out. Any help would be REALLY APPRECIATED. I was waiting over a week for the car so bummed abit but nevertheless I love the car. I had an A4 that was sweet and nothing leads me to believe this wont be the same.
