Question about 2003 Mercedes-Benz C-Class
Cod.fault p0172.type 203t mercedes
This means that it has detected a rich condition. You can get this with a dirty maf sensor suually caused by paper filters, a vacuum in a hose or connection or a fuel pressure problem.
Dirty mafs are easily cleaned even at home with maf spray cleaner. As long as you are careful not to physically touch the actual'sensor you can't hurrt it if it is still good.
