Just got a 2003 911 C2 cabriolet. All of sudden I got a check engine light. The scanner threw a 2096 bank 1 code   It was reset and it hasn’t come back for 100 miles and 1 week 

any idea what this mean.  Should I be concerned?

Possible fault causes
- Leakage in exhaust system between the two oxygen sensors
- Oxygen sensor upstream faulty (contaminated/aged)
