Bav Tech cable show Fuel Mixture Control codes. Dealer says they don't see them?
Check engine light has been on for a while. I took it in because I thought I was having a fuel injector issue and got fuel mixture control codes from the Bav Tech cable. I am on catless DPs, AMS intercooler, AFE intake, etc.
The dealer says they only see the cat inefficiency codes? Is it possible that a fuel mixture control code could be attributed to catless DP's? I wouldn't think so, and it makes me think they're pulling my chain because I have some aftermarket parts on the car. |

What code is it specifically? The cat inefficiency codes directly linked to catless DPs are 29F4/29F5.

I have heard some people say they think those are related to the 02 sensor. From the coding of injectors thread I am going to try to see if my injectors have been coded correctly to see if that's affecting my slightly rough idle, etc.
