Yep, 10740 and 10741 are cat inefficiency codes. Adjusting your o2 modifier will fix those.

The 10927 is fuel pump plausibility. Ignore it. Many stock and tuned cars alike throw that.

The 11566 is a benign tuner code that we mentioned in the documentation. We will get rid of it soon. Probably before we even implement the auto-clear function.

The other codes I've not even seen before. Worth getting them checked out for sure.

thanks it's actually 10797, not 10979 the last one that you said you didn't know. cleared code, adjusted o2 modifier down to 70%. no cat inefficiency codes any more. i still do have 10927 and 10797. i don't super worry about 10927 code since i don't have sign of hpfp failure but i'd like to hear if you can figure out 10797.

my car is few hundred shy of 50k and i'm going into dealer tomorrow morning basically to ask them to change cabin filter, wiper blades, which they didn't do at last service. i will also ask them to replace spark plugs, which people reportedly saying it should be done at 45k under maintenance program but my dealer never did it, keep saying they should follow whatever the car tells them to which oddly keep saying i still have 20k more miles.

since my warranty is almost out the door do you think i should even bother taking anything out? once they raise the car, they should see 3" dp in there too so i don't know if it is worth taking intake/charge pipe out before i going in. my SA told me they will do courtesy inspection and i doubt they will take a part anything so i may just put intake or something... any idea or suggestion?
