Audi A4, 2006 convertible : after driving the car 12 miles in stop and go traffic on a 2 lane street I noticed smoke coming from under the hood, not a lot. No warning lights on the dash. Temp outside was 75. So I drove another 2 miles, then I saw a lot of smoke coming from under the hood - I turned on the turn signal to get into the other lane and then the coolant low sign came on the dash. Then a lot more smoke. After letting the car cool in a parking lot, I added the coolant/water mix as called for in the service book ( had the staff at oreilly auto parts look up the correct coolant). As soon as I started the engine all the coolant ran out. I called the tow company to tow the car to the service station. It appears to be a cracked valve. Also 3 radiator hoses all need to be replaced. The car just had a full tune up 2 months earlier.
