Hello everyone,

I just bought my first mini a little bit ago, and now the check engine light is on with some weird codes. I thought all the codes started with PO, but these do not. Any help would be appreciated. It is a 2009 base mini with the six speed aisin transmission. I have a bosch scanner and this is what I come up with.
first code
20105, S2 solenoid (hex) 4E89 STORED

I think this has to do with the second gear shift solenoid

second code
10090 DFC_KATmin_C catalytic converter (Hex) 276A ACTIVE MIL

I am thinking that the converter is not getting hot enough?

third code
11675 knock sensor electrically maximum (Hex) 2D9B STORED MIL

knock sensor bad?




Anyway, any help with these codes would be appreciated. I also am adding pictures of the codes directly from the scanner, just in case i made a typo.
