I have the 20' inch wheels on my 2017 991.2 c2.  I'm looking for a set of winter wheels and snow tires.  I can mount a set of snow tires on my current rims - those are the recommended choice from porsche for the car.  I believe they are 11.5 inches in the rear.  Is there a 3rd party that makes wheels for this car that are narrower?.  Doesn't seem to make any sense to purchase snows that wide. Im located in the North East US so we get some snow.  

Hey - just bought a 991.2 c2.  It is really an exceptional car - I've read many reviews about it being different in a not so good way(sound, turbo) vs the 991.1 - that's just crap.  Drive them both - the new model feels faster sooner and that makes it feel much lighter - just a great car - but you have to drive to see for yourself.

I'm just getting used to the new pcm.  I have no experience with the unit in the 991.1.  After about 500 miles on the car I'd say it takes a bit to figure this out.  Id say problem 1 is it does not support wireless carplay - meaning you have to plug in your phone to get it to work.  Problem 2 - the pcm is really a nice device on its own and I'm not really sure carplay makes it much better - it actually might make it worse.  It took me 499 miles to figure out how to get it back to carplay mode from the radio mode.  By chance, I just noticed the carplay button on the home screen - you can't get to it from every screen - eg you have to go home to get back to car play - too many clicks when driving IMHO. It didn't come with a sim card installed initially and I just installed it now, it seems to be more active (my icloud stored music shows now) - not sure why music stored on my phone shows with the sim card and pandora plays just fine.  Using the iphone in ipod mode and the standard pcm nav is really very nice and well thought out - the carplay integration seems rushed - I hope they can update the software - make wireless work, make carplay reachable from any pcm screen and have a radio tuner in carplay - jumping back and forth seems silly.

Again, this is just a great car.

Fmscell - what did that work cost?

Thanks JFP - I will have these checked out.

At times this car is my personal road to Tuva.

Here's the screenshots of the P0021 code and the actual cam deviation values - bank 1 is at 5 and bank 2 is at 1.

this is a 2004s with 78k miles - 

I've had the car for 2 years now and this one keeps coming back - changed the oil a couple of times and ran a can of cleaner through it.  

Any recommendations on the next steps to resolve this - I'm thinking for time and money involved it it maybe just live with it.  If it's some 5k chain replacement - car will be someone else's proud new owner.

So my fuel pumps quit and left me stranded. Had to call AAA for a tow - first time I've ever towed a car.  Only bright side - it was a beautiful day and not too far from home.

What do I need to replace now to make sure this doesn't happen again.  The car is a 2004s with 80k on it.

These codes are the fuel pumps telling you they are going to die and leave you stranded somewhere.  First time I have ever had to have a car towed because of a mechanical failure.

Hi brody13 - 

did you ever resolve this issue.  I have the same problem.

Both of these appeared on my car last night.  There's an earlier thread that mentions this could be evap, mass air flow or fuel pumps.  The car as 77k miles should I just replace all of these things.  My only testing tool is the durametric - which in this case is not very helpful pinning down the actual cause.  

I cleaned the throttle body today - all went good with that.  I noticed that there is some oil film on the inside of the intake manifold.  Should this be there or does this need to be cleaned as well.

Wish I did it earlier - the car is vibration free.

With all porsche parts and independent shop labor, the cost was 900-1000 USD.

The labor was 5 hours.

Good luck.  If I had a cayenne with vibration when I started the car, I'd change the mounts.  Might be worth starting with the dog bone mount first - its the least expensive one to do.  I did the dog bone, the two lowers and the transmission mount - vibration is gone.

Replaced all of the engine mounts - lowers, dogbone plus the transmission mount.  There is still a small idle drop when coming to a stop, but it's no longer transmitted through the car.  

completely different car.

key tip is to put the internal balljoint on first and make sure you unclip the retaining clips on the receiver nearest the tailgate.  I used a snow shovel as a helper to hold up the tailgate.  should take you no more than an hour and 1/2 - last half hour is putting the bits back on the car.

I bought this and was able to install it - you need to clear 3 of the clips for the cap to come off.   It did make a big difference in idle.  Also did the two breather hoses - the guy before me put electrical tape on them to stop leaks. 

Almost done - onto engine mounts. 

Has anyone used this?

I think this is the next set of steps to try - http://www.pelicanparts.com/techarticles/Porsche-Cayenne/69-FUEL-Fixing_Common_Vacuum_Leaks/69-FUEL-Fixing_Common_Vacuum_Leaks.htm

I've had the same issue - in my 2004 CS.  Turns out some dude taped a broken vent hose from the separator to the intake - $150 later and a new vent hose the vibration its nearly gone, but not 100%.   I'm guessing this could be another hose or engine mounts or maybe the dogbone mount.  It would be great to know how to smoke test the system - anyone have a diy on this?

anyone had good luck with any aftermarket catalytic converters?  What brand did you use and what was your experience?

Have the same situation - but my passenger side works and drivers doesn't.  The dealer needs to take the dash apart to find the busted motor/actuator.  In my case they can't get to the diagnostics because of a short - so its 500 to see what the problem is.  

Many thanks Loren for jumping in here.  Can you post the workshop instructions or tell me where to find them in the manuals.  

I'm sure many of the member here will be replacing their cats at some point so a DIY would be very helpful.  

Thanks

2 hours per side sounds realistic.  Per the dealer it does not require dropping the engine.  I'd love to see a diy on this as well to see what's involved.  From what I can tell, you need to unbolt both ends and remove the o2 sensor and then reinstall.  10 hour seems like a very long time for this.

Thanks for the reply - 

Front Cats.  I took it to the dealer to get them to diag.  Its amazing it take that long to replace these - 10 hrs is a long time.  BTW, Its an 04S with 72k.  

Hello - What's the procedure for replacing the catalytic converters with new oem ones?  How long should this take?  Dealer is quoting 10 hrs

I will ask the dealer. The car is new to me and the codes have been there for a wile so they failed some time ago. They only have 70k on them so it seems early for a failure.
