MAF reading at idle and Throttle Position %
Hello everyone, My W219 CLS350 M272 having codes P0172,P0175,2092,2096 Rich fuel at idle on Both Banks.

Please share your MAF reading at idle and Throttle Position %.
Mine is around 7-8g/s at 650-700rpm with 12.5% Throttle

It was the MAF, replaced it with the new one and fuel trims are back to normal.
New MAF reading is around 4g/s at 600rpm
