Well,
Thanks for the info. it explains the function of the electric suction fan. however the code i got says open circuit. trying to figure it out where the open circuit could occur. Have VIS/ASRA software but I can't find the electrical diagram. do you have more info on this topic, specifically for C320 gas engine. any suggestions appreciated
