My motor is making a ticking noise between 2000 and 3000 rpms. when i pop the hood and listen with a scope it sounds like it is coming from the vanos. is this a known prob? is it a major prob? i am worried. help please. also i'm going to do a tune up soon. any sugestions for spark plugs.
all u have to do is take it to the car to bmw ..pay the 50-100bucks
and they'l let u know
plus could be three things
or depends on the type of ticking noise
could be your chain guides (tentioner )
mine was makin a ticking! i thought it was the valves...but instead it was the fan shroud just hardly touching the fan.....the ass who used to own the car must have taken it to some asshole that put pull ties in it!
