...and no, its not coming from the passenger seat!
Hi guys, been a lurker here for a few months now having picked up a '99 C4 Cab at the end of September. Keep meaning to start a thread on it, I'm sure I'll get to it one day.
Anyway, after some advice if I may - I have a whine. It was apparent when I purchased the car but it wasn't too disturbing and had a PPI at a specialist who gave it the green light so didn't suspect it to be anything to worry about. Anyway, the more I drive the car the more apparent the whine is, to the point where I think it may even be getting louder/higher pitched at times. First thing I did was replace the belt and have recently replaced the bearings in the tensioner & idlers. A friend suggested I run the car without the belt on idle to see if the whine is there and it is so this rules out any of the other pulleys on the belt system presumably?
In my Internet hunt for answers I came across a thread on PH with videos of what sounds exactly like the whine I'm getting. The car had recently rebuilt at Hartech and there are a fair few comments from people saying 'thats normal' including from Hartech themselves but Im not convinced that is the case, certainly for mine. As I say, the whine appears to be getting worse and is very audible in most driving conditions suggesting something isnt quite right.
Anyway, link to the thread below for the videos of what I'm experiencing -

PS - Im discounting the SAI as this noise is constant, not just on startup but please advise if you think this may well still be the culprit.
Any suggestions or advice gratefullly received as its somewhat putting a dampener on what is otherwise a fantastic experience for my first Porsche!
TIA - Rob
