You guys...and gals are great, lots of good information to help. All things considered, I was starting to think the Cold Air setup was making the car whacky. So after pulling the same codes over and over, I took the car to a St Louis BMW authorized repair shop called Bimmers R Us. Local car enthusiast/mechanic that started fixing BMWs in his garage for himself and a few firends. Long story short, now he has grown to usually having about 10 or so BMWs for sale as well as 3-4 bays for repair. He has all the
BMW computer software that is linked back to BMWNA. Known the owner for a few years so he lets me back in the shop. Told him the addition of the CAI has created the previous posted issues.
He checked with the super hi dollar BMW link I-Pad looking equipment and pulled the SAME codes as my Peake Research code tool !! Although the mechanic I was hanging with explained the diff between clearing the codes...but also clearing the Adaptions..We did both..codes and Adaptations. Let it idle for about 3 minutes and then went along for a ride with the mechanic. Man...we went for a spirited drive. Then back to hookup the BMW link. went through all the base functions and it came back NO FAULTS.....WOOOOOHOOOOO. It was running perfectly...with the CAI on !!
The cars adaptations evidently had to be reconfigured/reset to go out there and see the new CAI and make it part of the "family" so to speak. Its now happy and has no problem with it. INTERESTING NOTE: On the fault tool they had the capability of checking voltages across all the sensors. All the unique values we within spec. The interesting part was that the Mass Air meter is seeing a bit more air running across it due to the mass of the air was up near 20.1 kg(?)/hr. The mechanic stated that it usually measures 19.1 or 19.2 on the upper end of the scale. Mine is about 20.2...this is due to the CAI sucking more air. The car is OK with this increased movement of air but it had to become part of the engines management sytem as normal. The 7 is running like a top....for now

DIAGNOSIS: SOFTWARE ADAPTATION TO ACCEPT CAI.
