M57 slight knocking sound on idle
Hi guys, started hearing this slight knocking sound when idling, when i press gas pedal it’s faster then stops completely and when i let go of the gas pedal and the car is at idle rpm again the knocking sound comes back in like 4 seconds
Don’t wanna be too quick to judge but it seems like a piston might be saying goodbye Any thoughts ? Video below : https://youtube.com/shorts/XK8gLGOoa...iVmqMGheBWgoLh |
