I have a 2001 Audi A4, My car will not go in reverse. When I look under the car I notice there was puddle of oil. Can this be the problem?

The best balance of price, quality, availability that I have found is Mobil1 synthetic - it's on Audi's approved oils list. With the 2.0T engine, you absolutely want to use synthetic (the Audi turbo fours are known for oil sludge issues), and you want to do a SeaFoam treatment every 15k miles or so - that combination will keep your engine in great running shape.

The car has entered into fail safe mode. It wil not allow the engine to rev high but allows you only to get to a mechanic or to get some oil into the engine. What's the level like? Is there any trace of leakeage?
