  1. Does anybody know, which information are shared in the comfort can between cluster, HVAC and radio? I think speed and illumination is required for the radio. But what is required for the HVAC, for instance? only illumination ? Since I have removed the radio, the CAN Ring is interrupted and probably not any information is shared anymore, even between cluster and HVAC.
  2. Yes, but the vacuum shall be stored in a tank. So I should be able to close the PSE without the engine (and air pump) running as long as the vacuum system is tight. If not, I have to look for leakages as per above. Or am I wrong?
  3. If the additional air changes the sound so much in cold condition, I am thinking now, this has me made thinking, the PSE didn´t close prior to start. Can I somehow check if the PSE closes without starting the engine?
  4. Thanks for all the answers. @RFM Yes, it is louder and a different sound. But it is more a crackle sound than a howling sound. Can this really be the air pump? Or is this a result of the additional air, that makes the engine sounding like this? With my Durametric I could activate the air pump to see, if the sound comes from there. Can I do this without problems with engine running? Or can this be dangerous for the engine under certain conditions? How can I check, if the vacuum system is leaking and where? Thanks again, Gert
  5. Hi, I have a factory installed PSE in my 2004 C4S. If I go to work early in the morning, I want to start the engine in quite mode and therefore turn on the electrics, switch the rocker switch to quite mode and then only start the engine. However, it takes some time (about 30 seconds) of driving until the sound becomes silent. Also if I leave it in the loud mode it is much noisier in the first 30 seconds. Is that normal? I understand, that the rocker switch (via the control relay) controls valves to pneumatically open and cloose the mufflers. Any hint appreciated. Thanks, Gert P.S. I have disconnected the speed signal from the relay
  6. Sure, but which terminals of plug1 are 30 and 31, if I look to the amplifier. My problem is, I am not sure which side is shown on the wiring diagram posted here! Is the harness or the amplifier side shown!!!
  7. Hi, I need to come back to the above 2002 Bose wiring diagram! I am not sure, if the plug 1 is shown from the harness side or from the amplifier side. Plug 2 I can recognize, because of the asymmetric shape (shown from amp side). I would expect the same for plug 1, but then the letters on the diamgram do not match with those on the socket. Can anybody confirm, where (especially) terminals 30 and 31 run to, please! Thanks! Gert
  8. Hi, I am trying to remove the MOST system of my 996 4S MY04 (equipped with Bose M680) to install an aftermarket double din (Kenwood DNX-5220BT) and so far I succeded. Currently I have the front and rear speakers of the Bose system connected to the speaker outputs of the Kenwood. In the second step, I want to put an amplifier in between for a little more power and the subwoofer. I could get hold of the amp and the additional subwoofer amp of the 2002 analogue Bose system, which should work with the original Bose speaker´s low impedances. Another advantage is the small size. The amplifier fits to the place, where my MOST amplifier was located. But, where was this additional amplifier normally installed in a 4 wheel drive 996. I could use the standard brackets then! Can anybody help, please??? Thanks, Thormann
  9. Thank you, I did it that way! However, this was not a blind plug in my car. There run cables for the Litronic/Xenon lights regulation! But there was still enough space. Thanks again!
  10. P.S. It will be different between Boxster and a 4wheel Carrera. I need a routing for a 4S!
  11. Hi juniinc, where did you run the wires from the back part of the trunk (whre the battery is located) to the front part of the trunk to the amplifier? I could run the wires very easily from the head unit to back part part through the hole behind the battery! However I can not find a suitable place to run to the amplifier! Thanks, Marco
  12. The speed and reverse signal are transmitted via the can bus to the CDR23 (C1 and C2). You would need a special adaptor to get the signals out of this (Dietz 61010). But you can get the signals directly from the cluster. You can find also terminal 86s there, that I prefer to terminal 15 (radio turns off after removing the key and not after turning off the ignition/engine).
  13. In the 2000 wiring, the CAN comfort did just connect the cluster and the A/C, the radio got analogue signals ! How was the CDR 23 integrated in the CAN comfort? Can I just short circuit the high and low terminals of the plug if it is a CAN ring? Unfortunaltey I do not have a 2003 wiring!
  14. Thanks! If this is a CAN timeout, then it is probably because of the CDR23, that I removed for an aftermarket unit! Can I fix it somehow?
  15. Hi, when reading the fault memory of the heating/aircon (system H01), Durametric gives me an unknown fault 38. I can erase the fault, however it always returns. Going through the 2000 workshop manual, the last fault code is 32. Any idea, what to do? Thanks, Gert
  16. Hi Tool Pants, From which control unit (or in which menu) have you received the datas on the screenshot. Unfortunaltey I have not kept in mind, when we hooked up to the PIWIS. Can I get those datas also from Durametric? I want to check once more, but it is easier to find a Duramteric than PIWIS!
  17. I know, and I do not want to compare! I will completely remove the MOST and install the 2002 Bose amp. Believe me, the two complete wiring sheets of the radio/speakers(2002 + 2003) would help me a lot, since I want to keep the existing speakers!
  18. @Tool Pants This is what I mean! The % difference is almost the same at my car (about 4%). Is this in every car or something special?
  19. Thanks again! When you recall the DME Datas with a PIWIS Tester, you get something like (Unfortunately I do no have a screentshot) Ignitions range 1: Ignitions range 2: Operating hours: KM: There was more, but I do not remember! The KM shown here are about 700 less than the total KM shown in the instrument cluster. What can be the reason?
  20. Thanks, Loren! But any idea about the discrepany between cluster km and DME km? What does the second number at ignitions with "h" unit mean?
  21. Hi, I have checked the DME data with someone´s PIWIS on my C 4S 2004 and it looks strange to me. The odometer shows 19.400 km, but the DME shows only 18.700km with 300 operating hours. Does it mean the DME had been exchanged? Number of ignitions range 1 is very high with about 15.000 and 1600h. Range 2 is 8. What does that say? I can not believe 15.000 ignitions in less than 20.000km. What is the difference between range 1 and 2? Can someone interpret this? Thanks, Marco
  22. Thanks! But it says, wirering is similar, only length differs! Anyway... Could you post the entire sheet of the 2002 and 2003 wiring diagram with Bose! Then I should have all information together. Unfortunately I only have the 2000 wiring diagram and this is still without Bose!
  23. Would be helpful to know, what is the reason for the discrepancy !!
  24. @Loren Of which car/year is the posted input/output diagram of the Bose system! In my 996 4S Coupe MY04, I have only 5 lead pairs going to tghe speakers plus another pair going to the sub! I have measured the resistance: One output seems to be connected in series to 2 speakers. However in the posted diagram 6 speaker outputs are shown, i.e. seperate outputs for all speakers. Where are the terminals (A1, A2... B1, B2...) located in the plugs? Thanks, Marco
