Hi guys been a while. I have a seat leon supacopa 1.6 tdi mrk2 2012. Problem is when idling I heard a bibrating rattle sound pushed clutch in was still there. But when I hold gear stick to the left or right it goes away. But comes bk when I let go. Cannot hear it while I am driving just at standstill. Thought it could be hitting something under the car. Any help would be appreciated. Thanks in advance
