Hi Matt, Sorry, I still haven't found out! The car is running smoothly since I've had it, so I have just made the assumption the whine is normal. I'm thinking of having a transmission fluid change at the next service early in the New Year to see if that makes any difference even though it's not yet due on the service schedule (I'm at 63k miles). Will post if there is any improvement. LEt me know if you get any alternative views though. Cheers.
Hi, well I managed to find (I believe) that the problem engines were from late 2005. Mine is early in the year so unlikely to be affected it seems. Thanks for the suggestion though. Also no fault codes apparent, so am at a loss now.
No, I only have a basic reader unfortunately and nothing was thrown up. Will need to take to local Indie for that. Are there any typical hoses or clamps that come loose or split that I can get to easily to check? All seemed OK top end of engine when I checked recently, and when I had a quick look underneath when I had tyres changed recently.
OK - sorry for the awful quality. The first is sitting on my drive, stationary not in gear and increasing revs to 3000rpm. The second is starting up, driving off the drive accelerating up to about 30mph (just over 2000 rpm I guess) up around the corner and then coming to a stop. And no, I wasn't driving under water. I hope you can make out the whine under all the other background noise. engine noise.mp3 driving.mp3
Hi. 2005 987 manual. While the normal low level transmission whine has always been noticeable, in the past weeks the car has developed a marked new noise. When I reach around 2,000 rpm a really high pitched whine starts up, drowning out the exhaust noise. The noise can be replicated when stationary and/or if I rev the engine in neutral. As such I have ruled out any wheel bearing related problems. Also the fact that it happens regardless of whether under load puzzles me. The noise is also apparent under engine braking/slowing down. The whine reduces as I get up to speed in 5th, but is definitely there in the background, just drowned out I guess. It's not a belt type screech and the serpentine belt was changed 5k miles or so ago. Noise is there regardless of engine temperature, A/C on or off, stereo off. The car runs, pulls and handles perfectly otherwise. I suspect (hope!) it's an idler or ancillary pulley/bearing and will get it checked out, but prior to that has anyone got any thought please? Many thanks.
