I have a 2001 Beetle, 2.0 engine. Beautiful car. I had an oil change 3 weeks ago and in the days following I noticed oil spots in my driveway. The oil light came on two weeks later. My mechanic checked to make sure everything was tightened in reference to the oil change, and it was. There was no oil leak present from anywhere on the top. He also said there was no leak from the oil pan and that area altogether, and said the leak must be coming from the flywheel seal. He said because I added new fresh oil the pressure went up and an already damaged seal likely couldn't manage anymore. I don't know anything about this stuff. Does this seem like the only possibility, the flywheel seal which would require the whole transmission coming out?
