You haven't given any relevant info, was there any car work done, anything replaced... Your best bet is to read the error code and go from there. If you want to risk it (and assuming you know how), disconnect the battery, wait a bit, then connect the battery back, this will clear the code then see if its comes back, on the off chance it was a just a random error. Good luck.

Hello, a bit off topic, where can I find the OEM part number/serial for the spark plugs that go into my (2010 Legacy 3.6R) car ??? tried looking everywhere and there are SOOO many choices/options. My mechanic said my OEM part is NGK 7505 SILFR6C11 Laser Iridium; but on his another catalog this is different (something like NGK LFR6AIX-11) and I could not find at the parts shop, it's always a letter or number different; such as SILFR6B11 or something like that. Can someone direct me to a proper source. Thank you.
