Hi - on my 06 CTTS, over the last few months I noticed  occasionally awful smell inside the cabin while driving. My research so far indicates that it is emitted from vents when AC system is on. Believe it smells like sth. burned, and is not present when I switch AC system completely off. Did anybody experience this before on a 955 Cayenne, Turbo or Turbo S ? Thanks in advance. 

PS.: side note. It may be coincidence or completely unrelated, but as far as electrical problems I am noticing for about comparable amount of time that the  horn is dead (silence when pressing the steering wheel center...).

problem solved and lesson learned. cabin filters can be as important as the respirators for the crew of eight under the hood, and might need as frequent attention:) Wonder why nobody came up with a suggestion, and searching by keywords for air condition smell does not yield any results. However, Just clening out makes a big difference. new one on the way....

That's funny answering your own post asking why no one thought about the filter and neither had you at that point. Hehe. I jest, not attacking. ......

It's probably likely you got oil leak ( common valve cover gaskets leak) which is getting burnt off and drawn through the AC. A new filter is freshly carbon impregnated so it absorbs the smell to an extent. Like airplane seats and farts.

thanks for the comment lewisweller. i think there is nothing wrong  to answer a question after having it figuring oneself, when prior either keyword search on a forum did not show results, or couple of days pass wo any suggestion to some problem stated. Reading all posts seems super inefficient, but a search function , blocking typically after 1-2 queries suggests that this is desired here. 

However, vapor of a leaking engine as root cause makes totally sense - especially for a 120k engine. i will keep this in mind for the next more serious engine work down the road.

Yeah it tickled my (wicked) British humour button, I didn't mean any offence. 

I often answer my own questions on this forum as despite the vastness of the Web etc amazingly hard to find info on some stuff, but it's good for someone else in future to have the answer too. 

What I do detest is the thread which lasts 8 pages and result in ......... No conclusion and goes dead arrggghhhhhh how annoying.

Sure- like the british way very much! As a german -  i am possibly just generally more for boring facts and not too much up for endless chat  :(  . I do find though the  concept paying it forward” reflecting my personal attitude. I document all my projects anyway in depth for myself, and have the desire to share when a physical solution can be much simpler and cheaper and often much quicker then often discussed.  i have also no doubt it was eventually discussed. it is just not easily searchable ( at least at a place where you would expect - like here on p-cars and dominantly diy-ers)

      My front wheel was making a rattling noise for about the last week, and this morning as I drove out of my driveway and turned the wheel, I could hear a loud popping noise coming from my wheel whenever I turned. My best guess is that I drove over a pothole and the control arm / bushing moved out of place. Would this be covered under the OE warranty? Or should I take it to a mechanic?

      Hi all. Was driving my 2003 996 cab 2 days ago. I heard a strange noise from the rear and pulled over. I smelled a burning type odor and a small amount of white smoke was coming from the trunk vents. Since that time the a/c is not producing cold air. Fan still produces plenty of air, but it isn't cold. Am I looking at a blown compressor here, or are there other possibilities? It gets rather warm in South Carolina, and sometimes rather than dropping the top I use the a/c. Any input from any of you would be greatly appreciated.
      Thank you in advance,

      Hi there, my Cayenne is telling me my driver's side door is open when it is not. This is causing the dome light to stay on. Not sure what the issue is and if can be fixed easily. Any info given is greatly appreciated, thanks!

      Hello everyone,
                Does anyone have or know where I may have the bolt torque specs for a 2008 Cayenne Turbo? I need pretty much the specifications for all the bolts and nuts that would be included in a block replacement. I'm getting the back rebuilt by 928 Motorsports and reinstalling with an experienced friend. However, it's nearly impossible to find the specs for these motors. Additionally, if there's a place where I could find a complete 957 workshop manual, could someone please advise? Thank you.
