You need to Replace the Catalytic Converter. That is what you are Smelling. It has Clogged up and will also Cause the Light on the Dash Problem. Please Rate My Response! Thanks!

I've got a '99 Oddy with the same symptom of gas odor inside and outside of the vehicle. Gas cap was secure and the level of fuel made no difference, so by process of elimination, I checked and followed the fuel lines and made sure there were no cracks that I physically could put an eye and hand on and eventually ended up at the fuel injectors and fuel rail. From there, all you need to do is remove the plastic cover plate from the intake plenum and the injectors will be exposed as well as the fuel rail. Turn the car on and wrap some paper towel over your hand like a mitten and run it over the suspected areas. You'll either find your leak there or the fuel filter located under the rear sliding doors.

I had a similar problem with my 1994 S420.
Before taking it to the shop check the following:
Distributor covers, Rotors and Spark Plugs. That's what my car needed. Before I did it two "specialized" MB mechanics wanted to replace the engine wiring harness ($1,000.00) and the other wanted to replace Air mass sensor, throttle valve actuator ($2,000.00) I hope that's all you need.
