P0171 indicates a lean condition. The most common cause of this is a defective mass air flow sensor. Also check if any vacuum leaks.Replace MAf sensor,if cleaning the MAF does not help.
Thanks.

I know what the problem is. It's going to cost u about $25,000 to fix the problem. Just buy a new car and dump that crappy piece of metal in a river. Mercedes Benz will never be on my wish list ever again. Even the mechanics can't figure out the problem with my check engine light after I pay $2,000 for a check engine light service. They F***** it up even more. My car now is in line to get a heart transplant because it's dying.
