COILS TSB - Page 5

Actually that stabilizer/torque arm was quite easy to remove (and necessary) to get the damn cover off to get to the coils. I also loosened the air pump over that side, again very easy. All in all it was pretty straightforward and not too bad.

All 8 of my coils were cracked, thus all 8 were replaced.

Just did the coils on the 04 CS today. Not too hard a job. Definitely a DIY'er. Took me 1.5 hours. Funny how the stealer in MD (was at summit point when one coil crapped out) stuck up my u know what and charged me $400 to change 1 coil. 2 hrs labor for 1 coil. what a joke. Dont work around the motor mount, disassemble it. quite easy. Remove the 12pt bolt and loosen the nut on the fender side. It will fold back outta the way I also unbolted the air pumps and folded them up outta the way. Everything else straightforward. The passenger side plastic cover kinda tight getting it out but it will clear the air pump bracket. Here are the little culprits. I gave them each a sever tongue lashing before sending them to hell. Funny how they all cracked identically.

Gets Bosch their ISO 9000 certification. The product may be crap, but if it's consistent crap they will be certified!!

Even funnier that all of mine were cracked in exactly the same manner! LOL. I agree with ya, as I stated before, easy job, dealers ought to be shot for charging so much for things like this. I mean, I know it's a Porsche, and higher end auto, but there's a limit to the madness....just my 2 cents worth (would have been $4 worth if I were a Porsche dealer, haha!)

Just got my second set of coils in my 04 S, only have 30K on the vehicle. Started running rough again. Service guy said the part number had changed twice since my last set which was only about a year and a half ago. I guess Bosch is continuing its trend to make crap!

I just had mine done today on my 05 CTT, yes the new part number is:

948-602-104-05

Ditto that part number. I just had all eight cracked coils replaced in my '06 CS Tits Ed.

I had my 2004 Cayenne S coils replaced today. All of them cracked and cracked at same position on each coil. The old coil were 948.602.104.00

Seems like it wouldn't be a bad idea to slide some kind of temp-resistant rubber boot over these things when they are new, so if they crack no moisture could get inside. If I buy a Cayenne sometime I may do that.

No, don't do that.

I plan on replacing my coils soon.

I saw in wingman's post in the linked thread that he torque-screwed the coils fixation and the design cover ; is this necessary (read, should a get a torque driver or can I live without one) ?

Hand tight was fine. You will need a special socket for the stabilizer bar though (think it was a T50). Other than that a basic socket set and some patience with the right design cover is all you need. Might as well change the plugs while you're in there too. Have fun...

INURGRL951 · 02-24-2009, 01:32 AM

Has anyone had a problem with the coils ending in 05 im getting ready to do my plugs and my car runs fine should I just keep using the old ones( no cracks). I don't wanna buy new ones just to have them crack!

Here is a submission to the Coils story:

I just had my 40k service done. I certainly didn't get a deal on it. But since they were going to replace the plugs I jumped on the opportunity to get coils. They sold me the part for 18 bucks each and added no labor, although they still made out, given what I paid.

They told me that 7 of the 8 were cracked.

I didn't have much in the way of symptoms - just an occasional miss at idle. I have had occasional hesitation but I really think it is the transmission control program that causes what I have experienced as opposed to an ignition issue, but I could be wrong.

I bought my '04 Cayenne S new, I've had 4 carerras c4s and turbo over the past 25 yrs - perfect cars in every way, The Cayenne has been the biggest piece of Junk I've ever owned - worse than Ford expedition - and that was crap. Over the past 5 yrs it has been in the shop at least every other month. Transmission problems, Radio, suspension, Cardan shaft, Water pump, - Entire cooling system explosion - Flatbed etc. Now the coils and plugs $1,200.00 ???. The car has only 60k miles. Can't sell it - it's absolutely Porsche's version of the Chrysler K car. any suggestions??
