Where is the Mercedes Benz fault code p0172 stored?
P0172 MERCEDES-BENZ Meaning This fault code is stored in the Engine Control Module (ECM) when the ECM is no longer capable of controlling the air fuel ratio. For correct operation of the catalytic converter the ECM is required to keep the air fuel ratio (AFR) at approximately lambda 1, this equates to an AFR of 14.7:1 by mass.

What are the codes for Mercedes Benz fuel trim?
These codes are generic codes and not specific to M/B. M/B lumps all Fuel Trim problems (both lean and rich) into codes P0170 and P0173. They leave the determination to the scanner to point them in the right direction.
Why do I have a code set on my Mercedes?
Normally a code set during idle or light load is relating to an air leak. And a code set during high or part load can be a fuelling issue or an erroneous sensor signal. Need more information on how to fix the P0172 MERCEDES-BENZ code?

What does fault code p0172 and p0175 mean?
P0172/P0175 Diagnostic Theory for Shops and Technicians. When a vehicle has the fault code P0172 and or P0175, it means that computer can no longer automatically adjust the mixture between air and fuel. Code P0172 applies to Bank 1 and P0175 applies to Bank 2.
How much does it cost to repair a p0175 Mercedes Benz?
