Read evidence and context

Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

0 original-poster resolution reports. Counts can overlap; they are not unique people or a success rate.

0 discussions have direct query context; 0 report a fix in that context. Other evidence may inherit the discussion’s subject.

The noise is load under load (50-65 MPH), any gear, doesn't change with cornering.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

1 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 1 / ORIGINAL POSTEROriginal post

When I bought my pcar (2000, coupe, 6sp, 38K) it was CPO. Bought it 6/05. In July I had the dealer investigate a driveline whine at 50-70-MPH under load. They found a nail in a side wall on the rear, replaced the tires and stated it was normal. It was better, but the kind of better you get with new tires (Dunlup SP9000). The RO states worn tires, but I kept the good one cause it was at about 1/2 tread depth. The noise was still there but not too bad and I assumed this is how a Pcar sounds (this is my first). A year later ( 8/06), my ignition switch died and the car was towed to another dealer for repair. While it was their I asked them to check it out. RO states no abnormal noises other than tire noise (10K miles since previous RO). In 5/07, brought the car in for the mechanical inspection of the 60K service (I did filters, plugs, coils, oil) myself. I figured I'd get this done as the CPO was about to end. No issues found other than recommended an alignment. Finally, last week, I got to drive a 2001 with 25K miles. No noise like mine. So now I'm convinces my differential is out of alignment or has a bad bearing. The noise is load under load (50-65 MPH), any gear, doesn't change with cornering. The drone makes driving the car a real drag for any distance. So I'm looking for recommendations on how to get Porsche to address under warranty as I complained two times in as many years when it was under CPO. Thanks for any advice.
