    Porsche 911 996 C4S Cab
  1. Now that sounds like a fun plan @JFP in PA :) If I wanted to try by temporarily removing the speed sensor wire from the relay do you have any idea where I could find that? Someone told me I can disconnect that also but I'm not sure where it is other than the passenger footwell (or did they mean the right footwell, which on my car is the drivers?).
  2. Super thanks @JFP in PA Defeating the system is now my aim :) Someone else suggested that I can disconnect the speed signal wire to the relay in the passenger footwell?
  3. 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.
  4. Good to hear from you @mikemcmo . I actually had a play since I last posted. Looks like when the regulator is new, that spring below them is fully compressed and the pin furthest from it will have tension (as well as possibly the others). You can then release the cable cover a small amount each time the cable has stretched a bit. Not sure of the process as you only want to let out 1 each time not all of them. In my case, My regulator was already all the way out. The easiest way to tell where yours is in the series is that the upper pins will have no tension after they have been released and when you pull them you will see the cable in the gap not the cover. Mine only had tension on the last, so I’m already at max and it’s new regulator time.
  5. I would also like to know about those cotter pins. @MikeMcMo did you ever work it out or try removing one?
  6. Hi all, I’ve been trying to upgrade my factory PCM2.0 since it had a little short and died, but so far I’m still pulling my hair out after hours of trying to get it to work. i have a 2004 996 C4S cab. I have a Pioneer DAB130 double din unit (https://www.pioneer-car.eu/eur/products/sph-da130dab) with the Connects2 CT51-PO04 (https://connects2.com/Product/ProductItem/CT51-PO04). Although that connector harness says for the 997 in many places, it appears as mine is an 04 996 that I have a lot of parts that are also in the 997... i.e. optical connections between phone, amp and cd changer. Sp I’ve connected it up to the vehicle harness, connected that adapter harness to the standard harness that comes with the radio, plugged it into the radio, and also plugged in the dual aerial feeds to a Connects2 aerial adapter. However, nothing happens when I turn on the ignition. I’ve checked that I have voltage at the back of the radio which I do. I’ve checked the wiring looks right according to the supplied diagram. I’m at a bit of a loss. Ive also checked all the fuses in the fuse box in the drivers footwell just to make sure they are all goo, which they are. Surely these adapters are wired correctly so I don’t need to start cutting and joining wires. Any thoughts?
