Today morning when I was in my car on the way to my office, I heard some unknown sound started all of a sudden, it sounds like thud thud thud. I think its from right part of the car under the bonnet. I am sure it wasn't there when I started driving this morning.
I parked my car for a while, kept engine running, opened up the bonnet and tried to find the issue but I cannot hear the sound. Quickly I checked some belts, pipes and other stuffs under the bonnet, also checked front wheels and checked all meters & lights on dashboard and found all well. As I started driving, again I was able to hear the sound.
I have already contacted my mechanic and have planned a visit coming Saturday. Hope nothing happens till then.
But I am curious, What can be the issue?
