  1. No previous body work carried out. Nothing has fallen on the window. No one has touched it. I don’t know but does the sealant lose (part of) its flexibility over the course of time. I’ll ask the person who is going to replace the window. I had the front window replaced a few years ago. I think replacing the rear window is more difficult than replacing the front window. I could, of course, be mistaken. I have removed most of the window, but around the edges the sealant holds a lot of glass splinters. I’m afraid some/a lot of them are going to end up in all sorts of openings of the b
  2. Had it been a convertible yes, but it is a coupe. As yet it remains a mystery. It must have been caused by tension in the window. There are stories on the Internet telling about Volkswagens which have windows that break spontaneously. jo996
  3. To my horror I discovered that the rear window is my 996 was cracked. I have no idea what has happened. The car is not used during the winter months and is parked in the garage at a constant temperature. No one has touched the car and nothing has fallen on the window. I have already contacted my Porsche dealer asking them what could have caused the window to crack spontaneously. As they had never heard of this having happened before they could not give me an answer. My Porsche dealer hires an outside firm to repair windows and as I do not want to drive the car without a rear
  4. Yesterday I asked where I could find the plug to drain the dif oil on my Porsche 996 Carrera4 Tiptronic. Thanks to members of this forum I now know how to do that. My next problem is a trickier one. I thought I had solved the problem of the oildrops on my garage floor. I thought they were drops of transmission oil. As I had already planned to change the transmission oil and the gasket I thought that would stop the leaking. However, as it now turns out it seems that the oil is coming from the rear dif. It's slightly wet. So a number of questions. Is there a gasket between the two pa
  5. I've just tried to change the dif fluid on my 996. Changing the oil on the front differential was no problem. The rear dif, however, was a totally different matter. I had already asked my Porsche dealer whether It was something I could do myself and I was told it shouldn't be a problem. Finding the filling plug was no problem, but finding the draining plug was. I simply couldn't find.it. So, is there a plug to drain the dif oil and where is it? A few minutes ago I also found a YouTube film in which someone is changing the dif oil on his 996. His differential looks different, might be a
  6. Hello Loren, Thank you for your answer. I tried the connector and it seems fine. I used some contactspray to make sure the contacts are OK. I checked the fuse (D8). I take it there is only one fuse for the spoiler motor. I have never had any problems with my spolier before. Never heard any strange noises. I hope the motor is still OK. The next step (before going to my Porsche dealer) is to check the wires. In order to do this I have to remove a black lid (I hope you know what I'm talking about). The spoiler motor is attached to this part. Can you tell me how to remove this lid? Regards,
  7. Hello, I have just encountered the same problem. Red warning light went on. At home I tried to operate the spoiler manually. No luck! I checked the fuse and its fine. I also checked the connector. Seems to be fine. I know that somewhere in the lid there are 2 (?) microswitches. Could they be at fault? I would also like to check the wires going to the motor operating the spoiler. I can't get the black lid off. There are just three tiny bolts left, holding the spoiler motor. How do I do this? Anything else that could be causing this problem? Jo996 the Netherlands
  8. Hello, It has taken me almost two years to finally find out where this awfully irritating noise in my sliding/tilting roof comes from. I must have removed the roof about a dozen times, but never succeeded in finding the cause of the noise. Yesterday evening I read all the TSBs on noises in the Porsche 996. In the TSB on noises in the trim panel area (Part ID 2/00 Number 70..) I read about complaint 10: "crackling noises at the frame of the roof lining for the sliding/tilting roof cutout". I removed the sliding roof and the panel. Then I put the roof back, but this time without the pane
  9. Hello Loren, Suppose it is the drive motor/circuit board which is at fault. I take it it would have to be replaced. Is it something I can do myself? A very difficult DIY-job? Have you got any idea what a new unit would cost? Jo996 the Netherlands
  10. Hello Loren, Thank you for your answer. It wouldn't really be a problem if I had to re-teach the memory of the sunroof a few times per year. In my case, however, it loses its memory within, let's say, 2 or 3 minutes. Where in the car is the memory of the sunroof located. Can the memory be accessed? Can it be replaced? Have you heard of the problem before? Is disconnecting the battery an option? It is a way of re-setting other functions. My car is due for its annual service this Tuesday. Can my Porsche dealer, for instance, reset the memory. Can they re-train the memory by means of a comput
  11. Hello, Since last week I've had a problem with my sunroof. The switch with which to open the sunroof, in fact, consists of three switches/positions. In order to tilt the roof, normally, I have to push the round 'button' in the middle of the switch. For some reason this no longer works. First I have to press the 'close-switch' a few times. Then the roof tilts and closes again. Next I can use the 'open switch' to open the sunroof. It then seems to operate fine, but unfortunately not for long. I have tried the 're-teaching' option. Again this seems to work, but not for long. My idea is that t
  12. Hello Loren, Spot on, the light bulb needed to be replaced. Changing bulb was a piece of cake. When I removed the instrument cluster I noticed that it had been out before. The paper seal at the back of the instruments had been torn. In my service booklet there are three modification entries, one of which reads: AY 83 Combi-instrument. Have you got any idea what was done? Thank you for your advice. jo996
  13. Hello, I recently noticed that when I switch on the ignition the red light of the safety belt in the instrument cluster no longer lights up. I even have my doubts whether it ever did. Could it be that the previous owner had the Porsche dealer switch this function off? Do I need the Porsche dealer's assistance to have this undone?

  14. Hello Toddel68, I have been thinking about installing a PSE for some weeks now and I have been gathering all sorts of information via a number of Porsche forums. There's no denying that www.renntech.org offers the best information. Within a few weeks I hope to start installing a PSE on my 996 C4 (November 1998). I have read that you also have a TSB in German on how to install a PSE. It would make the installation easier I think having both the English and the German version of the TSB, especially when having to do the electrical wiring. So, could you do me a favour and, if possible that
  15. Hello, I'm thinking of installing a Porsche Sport Exhaust on my 996C4 (Nov. 98). I have already found a lot of useful information on this forum, so I think it's going to be a DIY- job. I have already found out that I have to remove the driver's side front seat and the driver's side doorsill/ sill cover. How do I do that? Should anyone have any additional information which is useful, I'd be most grateful. For instance, is the PSE reliable. I think I have read somewhere that it is not possible to order the glossy switch to switch the system on and off. Is that true? Thank you for your h
