How's it everyone, so i took my 2007 c230 to the dealer because i can't seem to figure out why it is showing 185° on the dash and for some reason its affecting AC operations. Before taking it to the dealer i was on the forum and i had few suggestions on here,which is to replace the Ambient temperature sensor and or the evaporator temperature sensor. so i went ahead and replaced both sensor,but unfortunately those didn't fix the issue.
After the dealer completed their diagnostic test,they are telling to replace the computer module but its going to cost me 1200 plus the 355 for the part. My question is,how hard is it to replace the computer module and does it need to be program after replacement? If anyone in here have done this before or have any idea what to do please let me know. thank you in advance..
