  1. That is understandable. But I just find it hard to comprehend why the battery management menu for the iCarsoft unit had entries for all of the current Porsche models, including the Cayenne, but not for the Macan. Perhaps the Macan is unique in this regard?
  2. JFP, Thanks for the reply. I am aware that Porsche dealers use the PIWIS system to perform this function. What I would like to know is if there is any generally available unit besides the PIWIS that will perform this operation. The iCarsoft POR V2.0 unit is advertised to do this for the Macan. So I bought one and when I tried to see if it could do what was advertised, I found that it would register a new battery for every Porsche model except the Macan. I returned it and got my money back after their technical rep told me they "are still working on it". Still looking for a re
  3. Still no comments on this subject? Has no Macan owner yet replaced the original Varta AGM battery at other than a Porsche dealership?
  4. I tried doing a search on this topic, but was unable to find a definite answer. I am wondering if anyone on this forum has actually replaced their Macan's original battery other than at a Porsche dealership. The OE Porsche battery is a Varta AGM 12V 92Ah 520A DIN. I have seen what I think are exorbitant charges for replacement at Porsche dealerships. Contrary to what some are saying, I believe that AGM batteries, being completely sealed and presenting little or no hazard of acid spills, may be shipped. Sunset Porsche seems to have about the lowest price I have seen at $331. Varta does not s
  5. JTT, Can you tell us what aftermarket HU and amp you used? Thanks.
  6. OK, an update. I fixed the problem and I want to thank all those who contributed their helpful comments above. The problem was that the linkage from the motor to the "blending flap" that controls the mixture of heated to chilled air slipped down off of the blender flap and allowed only heated air into the mixing area prior to delivery into the cabin. The exact problem was that the two tiny plastic tabs that hold the final connection "plug" up from the controller motor linkage to the bottom of the flap broke off and allowed the "plug" to fall down and disconnect from the control linkage. Th
  7. DBJoe996, Thanks for this link. It provides a much better image than what I have seen before. I still can't see the actual flapper though.
  8. fpb111, thanks for the link. This looks like what I need to get started. It would be great if the link in that document to "Porsche 986: Air Box (3.31 MB)" was active. Anyone have any idea of how I could get access to that document that is referenced? Thanks.
  9. Thanks for the suggestion, but that fix is for the 924/944/968 group where you can actually see the parts. Unfortunately, the 986/996 heating/AC unit is essentially a "black box". I need to know what is inside it and how to make a repair, if that is possible.
  10. I have a 2003 996 Carrera in which the AC abruptly started blowing only hot air, regardless of settings. Not a Freon charge or compressor problem. I have been told that it is likely that the linkage from the motor to the "blending flap" that controls the mixture of heated to chilled air has broken or slipped off and is allowing only heated air into the mixing area prior to delivery into the cabin. Here is my problem: Although I have a PET parts diagram, all that it shows for the heating/AC unit is basically a "black box" without any details about what is inside. Therefore, I cannot ima
  11. I have always used regular Permatex anti-seize for this purpose. There is a recommendation on the label to use it with spark plugs and I have never had a problem using it before. I can only imagine that I used too much this time, although I thought I was using the same small amount that I normally do.. If memory serves me correctly, I removed it from the plugs by rubbing off as much as I could with a cotton cloth followed with a cloth soaked with xylene. I did not attempt to remove the anti-seize compound that was likely left in the threads in the engine head, so there was undoubtedly some
  12. Just a short comment about the use of anti-seize compound on spark plugs in engines such as these. For some time, Porsche has advised against its use. The reason given is that the use of this material may insulate the plug from the engine block and allow little or no ground for spark discharge to occur. Nevertheless, I have always used it on all on my cars, including my 2003 C2, without problems until recently. I did have a serious problem when changing the plugs on our 2008 BMW 328xi. When I was finished installing the new plugs, the car ran erratically and gave fault codes for misfiring
  13. I agree. The important thing is to keep out any additional moisture. The reason for annual or biannual changes of brake fluid in our cars is primarily because the reservoirs are generally open to the atmosphere and therefore the fluid picks up moisture from humid air. Of course, if you are tracking your car, the heating from the brake calipers will also degrade the chemical nature of the fluid over a fairly short time.
  14. Actually, there is no chemical reason to think there is any finite "shelf life" for completely sealed, unopened containers of brake fluid any more than there is for unopened motor oil as long as there has been no exposure to elevated temperatures. The fluids are basically inert, long-chain polymers of ethylene glycol and related substances that won't react if there is nothng for them to react with in the container. However, if the container is opened to the atmosphere, these fluids are "hygroscopic", meaning they like to gobble up atmospheric water that, as stated above by sburke719, lowers
