YES!

From what my dealer told me - you need multiple misfires to trigger and engine light/code.

'04 CS, no coils yet, 28.5k mi.

HOWEVER - every once in a while I will get a brief misfire sitting at idle. It is very sporadic, but I am watching all these comments with interest. I am into my ext warranty (3rd party) so when coil time comes I will have a good chance to test it.

Really looking forward to that.

No driveability problems, other than the standard issues with the tranny program that second-guesses your will to motivate.

Will someone please describe exactly what the "coils" are? My car suffers from many of the symptoms described in this thread and I would like to sound semi-intelligent when I as my dealer to fix the problem.

HD2pct

DMD, if you say "coils" they will know what you mean. If they don't, well....get in your car and get the hell out of there.

They are the individual ignition coils that are physically attached to each plug.

JFScheck

That's it - get it fixed now before your warranty drops dead!

JF , I agree. What is weird is that I will be on one trip where it happens a dozen times and another where I never sense any issues at all.

My dilemma is that I am pretty sure that factory has run out as of July, and EasyCare ext warranty is in. That means that if all goes smoothly, they would replace one.

Then in 5 months they would replace 3.

Then in 12 months they would replace 2. You get the point.

I am hoping that the dealer will cut me some slack, but it's doubtful.

Our Rockville dealer told me that "Porsche will now replace one - if the car comes back with another bad one they will then replace the rest of the seven"...

HD2pct

Well, that provides a roadmap! Worst case, I have "one", based on my symptoms. They can do that when they do the PCM upgrade,.

When I take it back and the house is still not in order, we'll push for 7 more.

Actually the techs have been directed to replace all coils if they are the 00 part number, if one is bad. Cant remember if thats the same for 01 PN.

I hope that is the case! It does make business sense for Porsche in a number of respects.

I think you guys jinxed me. I came around a corner, in too high of a gear of course due to the fine adaptive throttle, stepped on it and my car stuttered like mad for a couple of seconds. Does this sound like a coil problem? I noticed on the way home the vehicle didn't seem to be pulling very hard under acceleration (I have a 2004 CTT with just under 30K miles). BTW, I've been getting a message that the car is due for service in 1700 miles, but I am not due for service until 40,000 miles(?). Any thoughts would be appreciated!

Known issue. Your dealer will clear the "Service in xxx miles" msg in about 30 seconds.
There are Cayennes coming off the truck, brand new, that display the same message. Normally cleared/reset at PDI, port or dealer.

Yes, it's on the "list of things to do", but don't count on it getting done, remember, profits, profits and profits.

HD2pct

I think what you have experienced is PSM trying to show how "smart" it is. That can be maddening and in my mind, a little dangerous. If it "stuttered" as opposed to simply hesitated, you might ask the dealer to reset the transmission control program.

At least that is my experience. Others may disagree.

You'd probably be more likely to feel a coil issue at idle because misfires are more easily detected then.

Thanks. Something strange is going on. I went out to the car this morning and it was completely dead. Neither FOB would open the doors. I opened the door with the key and tried to turn the car over -- all that happened is that the key will not come out. Porsche roadside is towing it to Pepe in White Plains. I think it is just the battery but they want to tow it in anyway.

EnigmaWmn

My condolences re: Pepe Porsche ... pray that it IS the battery and not something a bit more complex. They're not too good with fixing things, in my experience.
