Hey guys, I just bought my first STi, infact my first Subaru all together. It's an 06' with 34,000 miles.
I do however have a question...when I went to the dealership the check engine light was on. They said it was because the exhaust was aftermarket and that it had thrown the code. (exhaust is the only mod on the vehicle). When I hooked an OBD2 scan tool to it, the scanner says it cannot establish a connection. Can anyone explain what might be the cause of this? or any info on why the exhaust would set the light off in the first place?
