so I'm going round and round with the dealer on issue, can someone tell me if there is a bung welded into the lower oil pan on the 4.2 v8 s4 or are the threads just tapped into the oil pan casting. the dealer actually sanded on my oil pan and now a crack has developed around the drain plug and I'm 98% sure the oil leak i have is coming through that crack.
