Code: P0171, P0170 and P0140. E200 kompressor

2004 E200 kompressor, w211.

On my way home check engine light came on, car drives normally and idles normally both hot and cold. since the scanner is generic i'm not sure on how to tell what those codes are.

You can start by deleting the codes, and wait to see if they are temporary. Check them again after a drive and not wait for the CEL to come up. The first code to trigger is the first sign, the next one is sometimes a consequence of the previous one

Did you read the thread, or just the first message?

Start with the suggestion for MAF, then O 2 sensor. Diagnosis/triage and analyze the data
