Hi guys, need some help diagnosing a problem on a 2004 bmw e46 318i n46b20A.
Problem: When the car is at normal operating temperature, upon slight acceleration ( between 800rpm & 1300rpm) there is a kluk kluk/knocking noise coming from the bottom of the motor.
The car has been to 2 mechanics already and they have between the 2 of them probably changed every part there is to change with no success.
Big ticket Parts that were already changed:
-lifters
-camshaft position sensor
-coil packs
-oil pump with balancing shafts
-vanos units
-vanos solenoids
-valve stem seals
-timing chain/belt
-sump was dropped to check bearings ( according to mech- all seams ok)
Car drives very well, not smoking, no hesitation or any other issues
only this irritating kluk kluk (knocking noise)
Any help will be appreciated..
