I thought the same thing but the fuel pump/relay AND OVP are new. I talked to a friend of mine who is a MB tech and he said most likely a loose pin at the OVP relay if the relay was replaced. His logic was that the only thing in common between the O2 sensor and the ABS light was that relay. I went under the hood and wiggled the connection a little and this morning I got slight different results. The car started better but the ABS light still stayed on. I let the car run for like 15 seconds then restarted and it purred like a kitty without the light so I think I am on the right track...
