Make sure the oil fill tube isn't cracked and that the seperator isn't stopped up and blowing oil. Both will cause passenger side leaks.

Those pesky CKP sensors will do it everytime. It's even more fun when they decide to quit on the way to work...so I've heard lol

Not sure what those codes are for but another problem area on those 986's is the oil separator. If it collapses internally the car will suck air through the filler cap and cause lean codes I think. With the car running try to remove the filler cap. If you can hear air sucking through the cap then the separator is faulty and needs replacement. These things can go bad and not cause any driveability issues until they fail completely and the car burns large amounts of oil and idles rough. Hope this helps.

I have to apologize to porsche 356 I somehow thought you had a 996TT didn't think about the Cayenne. Guess I look like a jerk now Ha! I never put a starter on a Cayenne but it doesn't sound like much fun though. Let us know how it went.

Look on the passenger's side of the trans tunnel If I remember correctly since the TT's use air cooled style blocks I think it is actually on the outside on the Trans tunnel. Hope it helps

Where exactly is the V on a flat or horizontally opposed engine? Just joking I knew what you meant but it was too good to pass up. They arent much fun to get to though. Make sure the battery is disconnected before proceding with removal.

You can lower the engine by using a block of wood and a floor jack to support the engine. Remove the two 18mm nuts for the rearmost engine mounts then slightly lower the engine. 1-2 inches max as you don't want to stress any lines or hoses that are connceted. This should give you just enough room to access the area in question. It will still be a tight fit though but you should be able to reach it. I recently replaced DV's on one and I had to lower the engine to access them.

Have seen the bleeder valve housing leak on Boxsters. This only happened after the car was hot and while beiong driven. The coolnt was leaking in the form of a mist and the exhaust was burning it before it ever hit the ground. I had to add well over a gallon of coolant before I found the leak. I think the housing is behind the wall where you fill the coolant/oil. At least thats where it is on the Boxster. There were like 6 small screws around the top that had worked their way loose and allowing coolant to force it's way past. This will also allow the engine to overheat due to lack of cooling system pressure.

I have also seen upstream 02 sensors cause the CAT failure code in those cars as they will stop responding and start to mimic the voltage cycle of the downstream 02 making the DME think that the convertor is not opearting efficiently.

It is normal operation. The Dual Mass Flywheel(DMF) will cause the somewhat jiggly pedal and also a rattling noise when idling the car with the cluth pedal released. I wouldn't worry about it. Caymans are a blast to drive arent they? :D

Not sure which years exactly but some early Cayennes had a second battery in the back also one under the drivers seat. If yours has two maybe they checked one and not the other? A bad cell in a battery will also cause it to check good at times. There is a large ground cable at the fron battery could be loose. MOLL batteries arent particularly tough so I would start in that direction. Also you colud have someone check fuel pressure maybe there was trash in the filter. Hope this helps. If I come up with anything else I'll post it.

Im with magcuda the LH and/or DME might be getting wet after washing(Water leak at the base of the windshield). I would look under the hood and check the passenger floorboard area after washing to see if you notice any traces of water intrusion. If im not mistaken the coils on the 928 are on the inner fenders so make sure no water is making it around any water seals the hood may have.
