When the computer detects that there are two codes (1) when the failure light of Mercedes R350 is on, the air-fuel mixture in the right bank cylinder becomes lean and adaptively falls below the allowable limit (P 1072). 2 ... Check the OX data to ensure that the mixture is thin. 2. After the air flow meter and air filter become dirty, check whether the air intake system leaks.
