sorry to keep beating the dead horse...
v g, is it a 2 piece engine cover hence the 2 differend p/n's?
6K0 119 512C
6K0 119 512D
only difference i can think of is throttle cable maybe but isn't it DBW ?
Just a thought. Why does your cover has both part numbers? Does it mean that there really isn't a difference between LHD and RHD?
