  1. I've been struggling with this issue myself. My Cayenne was ALWAYS steady at 180, but it has recently fluctuated between 180 and about 220. I have talked with the dealer and they have explained the same as the above quote, that it is normal and in spec. That doesn't explain the change in my personal experience and from owner to owner on here. I have been thinking of replacing my thermostat, thinking that perhaps it is working but not perfectly. The dealer has talked me out of it thus far, but I'd prefer to have my car go back to the steady 180.
  2. I was wondering if it was possible to adjust the dampening of the air suspension and the speed activated lowering of the suspension? I know you can adjust suspension height via PIWIS as opposed to a module, is it possible to make comfort more comfortable? Also, I would like to drive in terrain mode on the freeway, any way to eliminate or change the speed of the auto lower? It looks like the new renntech module may do the latter, I can't confirm, but perhaps there is another way? Thanks for any info.
  3. Thanks for the reply, but I am specifically looking for the difference between do it yourself and send it in. Are they modifying different files, using a different tool than the dimsport MyGenius provided by FVD?
  4. I am looking into the various ECU tunes available. I am leaning towards FVD due to price and the DIY nature of the flash. I am wondering if there are any compromises by doing it this way. What is the difference between FVD's flash and a company like Evoms where you send in your ecu? Thanks.
