hi ive got a loud ticking noise after a run , I changes tone when the clutch is pressed aswell , only does it every now and again but think it might be the dmf , ive taken it to a garage and he says he cant hear anything , its not vibrating or making any noise from cold , sounds like an air leak but cant be , only does it when been on a run and parked up on the drive , if left for 30 seconds or more the noise goes away??? the car has done 103k and hasn’t had any dmf that I know of
