Hi guys, new user here. I recently bought by second 3.7 Q50 and noticed that when I put it into Sport, Personal or Eco mode, the drivetrain doesn't actually do anything, the car is basically stuck in standard mode, it has been this way since I bought the vehicle about a month ago. I had a 2014 Q50 for 2 years before buying this one so I'm very familiar with the drive modes and how they're supposed to feel. I recently had a CEL come on for a misfire on cylinder 6 so I thought maybe the car disabled drive mode changes as a precaution? I cleared the code a couple days ago, and last night I replaced the spark plugs and installed a Takada Stage 2 CAI, left the battery disconnected for several hours, and the car runs very smooth but drive mode selector still doesn't change the vehicles performance even thought it says it does on my dash & display. Also, when the car is in ECO mode, the green indicator light by the speedometer doesn't come on either, further confirming that the car is in Standard mode. I've researched online for days and can't find anything, I even checked fuses and everything looked good, I'm at a loss.
