w202 c200 Kompressor Faulty

[Haliaktas]

Hello everyone,

I'm writing from Turkey. I have a 1999 c200 kompressor.

Nowadays, I have a problem with my car.Sometimes my car isnt open kompressor but sometimes it can open perfectly.So my komporessor isnt working regular.
Firstly my service replaced air flow meter to new one.But its not a solve my problem.After this operation,they try to connect my car to mercedes tester,but they cant see anything about engine failure.
Because Mercedes Tester can't read my car engine control unit data.Service said to me " your engine control unit is faulty.Firstly,you should repair your engine control unit then we can say your failure".
I dont know what can ı do ?? How can ı repair my control unit ?

Check all the air piping for the kompressor particularly under the airbox this can cause the issues you are experiencing, Highly Unlikely to be ECU issues
