My 159 jtdm has developed a quiet knocking noise from the engine compartment. You can hear it only at low speed when turning left or sometimes when going straight, but never when turning right. My Alfa guy can't find anything loose and has checked out the suspension and brake discs etc. He can only guess it may be the inner drive shaft bearings.
Has anyone else come across the same problem?
