Land Rover says some of its 2010-12 LR2 models may illuminate the Check Engine light and log O2 sensor trouble codes P2097 and P2099 in computer memory.
If there are no drivability symptoms associated with the codes and the freeze frame data doesn't show any reason for the fuel trim issues, the codes are likely bogus and caused by software issues in the PCM.
Reprogramming the module with an updated calibration is the only reliable fix. Check with a dealer for the application specifics of the flash.
