Hi Mr. Scott, I have another question about my 2009 Mercedes Benz b170(w245). The car growls whenever i put my car in drive while pressing down the brake regardless a cold start or during normal driving with the warmed up engine. I have changed the car transmission & engine mounting, so i believe its not that. I also read about engine growling in the internet and it says about coolant leaks, but my car coolant is sufficient and no overheating issues. My car have driver side drive shaft problem where it clicks when turning, anyway i plan to change it next weekend.
Please help me to solve my headache...thanks in advance
while pressing down the brake
did you check your brakes?
It's not the brake i believe, my brake is working fine. Just that everytime I put to drive with brake pressed on, it has growling noise... Could it be serpentine belt?
take it off and see
