If its not the Cat...or a leak onto the pipes...I hope you don't have the same problem as my wife's Jetta. The Jetta would be totally fine, until you hit the free way and drove around 120Km/h....after about 5-10 minutes at a higher speed, it would start to smell like a mechanic shop floor inside, it was also stuttering like the transmission is slipping... after changing the spark plugs, spark plug wires, cap and rotor the stuttering stopped, but the slipping feel and smell continued..... Turns out a mixture of coolant and oil was landing on the hot mani...and burning up and the smell would enter into the car....Turned out to be a head gasket leak, and apparently a crack in the block(VW said)...the car is also a 97....havn't fixed it yet, been in the garage for 6 months now....VW told me its going to be atleast $2000 in total for the repairs.....all this at 115 000 KM.

I think the tranny slips a little seems like, but the car will still accelerate with speed. So I assume the slipping is not servre. Once again the odor comes on when, say you're going at 60mph and you want to pass someone so you floor the gas till you see 100mph on the speedo. At this time I start smelling the burning smell like burning clutch. If I ease on the gas at 60mph till I hit 130mph the odor is very slight. I can maintain speeds at 110mph without any odor. So the smell comes on with sudden acceleration. I will check the color of the fluids just to make sure. I have a 1997 S500 with 5 speed. the tranny should be a sealed one. supposely maintanence free. There is no odor at any time other than fast acceleration high insanely high speed which should be normal for these autobahn cars.
