mac993 - Congratulations, persistence finally paid off for you. I think this thread leaves others with this problem with a positive thought that it can be accomplished baring any other mechanical issues. I think we all found solice with each others comitment to come up with answers and support for fellow rennlisters.

Just wanted to let you guys know my experience. Had the lovely intermittent horn issue which required disabling the battery/airbag for a DIY fix. All codes had to be reset and I had to smog the car. Stress! A drive from LA to Camp Pendleton in Oceanside (for the Marine Corps Mud Run - lots of fun BTW) and back in rather hellish traffic interestingly set all codes. This happened a few years back as well where I had to remove the battery, reinstalled it and drove about 100 miles and then went to the referee convinced they would be unset (back when you could go that route). Upon hookup I was told that all codes had been set and they would do the smog, but it was unnecessary to use them.
Many thanks to the always generous Chuck W
for the kind use of his Actron code reader. I originally got the entry level model (don't make this mistake!, it does not read readiness codes) and Chuck's did the trick. 
Have a safe and festive 4th. of July all!

I'm glad you finally made it "across the finish line" but I am still dealing with 5 incomplete codes on my car also after the horn ring replacement. I have done at about 10 drive cycles over the past few weekends and I still can't get get the 5 tests to complete. I did 2 yesterday with about 3 hours between the runs; same speeds and RPMs, same route, etc. No joy yet!
I feel bad taking the car to my mechanic just to do this drive cycle but I am starting to wonder if I will ever be successful getting this complete before my license plate expires.

It's bad enough our cars suffer this Achilles heel, with Porsche refusing to do anything about it. You would think they would at least provide some kind of "official factory tech bulletin" to all states requiring testing to explain the issue and that our cars do, in fact, run clean despite what the ill designed diagnostics say.

The issue is, Porsche will not admit that there is a problem with the system. The OBD II software written is considered propritary to Porsche and only they can deal with it. It's a product liability issue and recalls cost $$$$. Fortunately for them with all of these cars now out of factory warranty they could care less.

dmwallace- As the OP for this thread I feel your pain.... I was having the same issue as you for years. No matter how many times I did the cycle I couldn't get it to work. I think your cool down time is the issue. I have now successfully cleared the codes twice in the past few months (had to replace the altenator and disconnect the batt.). Both times I did the cycle one day then waited for the next day to try again and both times it cleared on the second cycle no problem. Also be sure to keep it below 30 and 60 as well as below 3k rpm and it should clear..... Good luck

Kika and mac993,
Thanks for the encouraging words of support! Yes, I have been doing the drive cycles < 30mph and < 60mph along with < 3000rpm. On my earlier attempts I had my wife timing each part of the cycle and reading the real-time monitor on my Acctron scanner. This past weekend I did not plug in the scanner until after the second drive cycle (hoping not to jinx it I suppose).
I'll try again this weekend and report back on the results. I will split the cycles between Saturday and Sunday to see if that helps me.
Thanks,
David

dmwallace,
You may want to increase the duration time of your 40 to 60 mph <3000 rpm time to between 35 to 40 minutes. Try to keep your RPM and speed as consistant as possible. This was the major change that I made to the drive cycle before mine set. Good Luck!
