Hi,

Recently I brought a private Mercedes C200 2009. It has a engine light with codes (P2188, P2263 & P3539).

Already cleaned

MAF sensor

Throttle body 

MAP sensor 

replaced some of the vacuum hoses.

new engine oil

new transmission fluid

Even after cleaning also no different in power. Check engine light came back again.

which parts i have to replace?

 


*fuel-Air ratio

These are generic codes related to the supercharger, vacuum leaks,.. I would take the car to a mechanic who works on Mercedes to figure out the issue before throwing parts into the car.
