My friend and I went to change my oil today but we think we have drained the front diff fluid by accident. It was a grooved pan under the car alittle behind the engine with a hex head drain. How do I put the fluid back in?? I have a 2000 s4 6spd. HELP!!!

 

audiworld and s4biturbo.com has some good things. .. but ouch...always open the bolt by a little then smell it or look at it under light or do soemthing!!! .... hope you didnt run it without fluid!
