I have a 2001 SLK 320 automatic it had a check engine light on and found that the EGR valve was leaking so we changed it drove the car and the light came back on with Adaptation at limit at idle checked with a scan tool and found that the MAF was bad replaced it and now am battling to reset readiness codes have driven the car for 3 day and am waiting for all the codes to be reset Dose anybody know how long it takes to reset all of the codes as I need to get my state sticker on.

Some codes will not reset themselves even after correcting the issue. Have you read the codes lately to ensure that there are none set at this time? If there are none set, you will need to clear them with an OBDII scan tool.

Good luck,

This code must be reset by a scan tool.






Have a great day.
