To all 996 owners with PSE, especially those with a 4S.
I think my 996 C4S exhaust behaves oddly. I think it's a fault but you might tell me it's normal behaviour. The problem is that I've always had this 'fault' on my car so I don't know if it's a fault or intentional behaviour. If you have the same car, perhaps you can shed some light on this.
When I start it, it's noisy and sounds great. It quiets down as it runs for the first 5 mins.
I have the PSE system and when I press the button you can audibly hear the exhaust note change - quieter when on and louder when off. Default is off so loud.
Here's the rub. Up to around 1500rpm it's got a good noise then it fades out to the point where it's so quiet it's like driving my partners Yaris. If I keep accelerating, when I get to around 3500rpm the exhaust suddenly gets loud again. I mean it's immediate - like someones flipping a switched marked loud. It sounds great.
It happens in 2nd and 3rd gears most noticeably and the PSE is in the 'off' position. If I have the PSE button on, then it's just quiet all the time and that works fine.
So why the silent spot?
I did read somewhere that German market cars might have had a system that turns on and off the PSE at certain speeds to prevent people driving round residential streets with a loud exhaust but information is thin and I don't think I was ever on UK cars.
I have also had a small go at checking vacuum pressure at idle on both sides of the Y piece in the engine bay but both hold good pressure. One side has only a microscopic leak but not enough to cause this kind of issue.
Hello Renntech Community. Hope everyone has had a lovely day/ evening. Well... After owning 2 previous porsche's there is no doubt we all run into A LOT of issues. I have an 04 Boxster S with 117K miles on her. Well taken care of, just recently had an oil change. While driving my car on the interstate i felt a drag in the acceleration.It felt like the clutch was slipping but after driving it a little more it cleared up... (Previously was an oil leak, I tightened the drain plug and added more oil prior to this incident and all was well) Then, while driving the car would accelerate any more, I attempted to downshift but it kept happening. The car died after I pulled off on the highway and after continuous hours of attempting and failing I called a flat bed and had her taken home. I ran tests on the relay, All is well with it. I added gas and a octane booster to attempt to clean it out. That didnt work. Checked fuses and those are all good. I suspect a fuel pump but Im not sure. Thank you!
- Hopefully this is all enough information to help me out
Hi everyone. My 2006 Boxster S suddenly started making a squealing noise. Noise goes away at higher RPM, only to come back at lower RPM and at idle. Not related to gear or clutching at all. Noise seems loudest at the rear of the car; I can hardly hear it inside with the windows closed. Is this a serpentine belt issue? Or the bearing of some engine accessory? I have 50,000 miles, and have already changed the serpentine belt once, around 4-5 years ago, just due to age of the car. I have not yet had the time to open up the engine compartment to look further. If it's a belt, then I would expect more noise from inside the cabin, would I not? I have attached a recording indicating the squeal going away when I rev the engine.

Not many problems with the car but cruise control doesn’t work and the spoiler only extends halfway or so.
Current actual problem with the car is that I can feel vibration or shaking in the steering wheel (and in the car to a much lesser extent) after shifting into fourth gear. After shifting into fourth gear, the shaking seems to persist even as I slow down, or after shifting into fifth. It will persist even if I shift into neutral but will stop after I come to a stop.
It’s strange to me that this is the case when gears 1-3 don’t have this problem. I am guessing that it’s an issue with bearings or alignment in the front wheels since i’m feeling the vibrations in the wheel but hopefully someone here has a better idea.
