Okay here it goes,
My car has been making this hissing type sound that I can't get rid of. I have only had the local BMW dealership service my car, but ever time I take it in (4 times for the noise) I get the same answer, "we can't replicate the issue"
I have had to suggest that they look into my lifters and the vanos solenoids (thank you e90post for the tips
) both of which did need to be fixed, but unfortunately, that didn't make the noise go away
I am tired of paying the diagnostic fee for the same damn issue and am hoping that someone knows about this.
