Hey guys , i'm experiencing a really ennoying knoking sound coming from underneath my golf gti mk5 when slowing down . I noticed that it's only happening when the car switches from 2nd gear to 1st , the sound is not very loud but it's really noticable . i changed all the mounts of the car also the axle , and it's still there .. Please help me because it already costed me a fortune to getrid of it , here in lebanon the parts are so expensive.
