Hey,
A few days ago the check engine light went on in my Subaru Tribeca 2008. I checked for the error code, it gave me P0175 - system too rich bank 2.
I cleared the error with a scanner and since then nothing had happened again. I had a similar error on bank 1 from around a month.

Does anyone have any idea of what could be causing this error? Is it anything major to worry about?

From thread on P0175:

"Check exhaust for holes, loose bolts, etc.
Check intake for holes, loose bolts, hose disconnection, etc.
Check fuel pressure
Check engine coolant temp sensor
Check MAF air flow data
Check MAF temp vs. ambient"
