Igntional Coil Replacement
Hey all,
2 weeks in a row after a heavy rain I have dealt with a rough idle and each time the check engine light came on. I cleared the codes once it didn't rain for a week then today here in Pittsburgh we got hit with a monsoon and again the CEL came on.
Codes were as follows...
P1362
P1361
P0133 02 Sensor Circuit Slow Response Bank 1 Sensor 1
P1363
P1372
I am being told it looks like bad ignition coils and my '11 Cayenne S just hit 74k miles. What is your average cost of replacement of all 8 coils? Does 800 bucks sound about right from the dealership?
Thanks!

From Pelican, OEM coils are about $50/each so if you did it yourself, it'd be about $400 in parts. Factor in dealer markup for the parts and labor, and $800 from a dealer is about what I'd expect.
If you're even a little bit handy, coil and spark plug replacement isn't that bad on a 958. You'll need a torx socket (E12, IIRC) and some extensions/articulations. There are helpful guides on DIY sections of rennlist and maybe here for all I know.
Be careful with bolts that hold coils to cylinder heads as they're aluminum so if you drop one in the engine bay, a magnet won't help you and they snap off very easily with minimal torque (ask me how I know....).

Just an update the coils were not bad and that is the bad news. Porsche went ahead and replaced the 74371 Cel Bank 1 Valve Control Solenoid for the rough idle issue. Test drove for a while and no codes. I get in my car make it 3/4 of a mile down the road and the CEL comes back on with the same damn codes. The next day I take it back to Porsche and the car is awaiting a new diagnosis.
What happens when you usually pay for a part that wasn't needed at the dealership? Am I screwed out of my 600 plus dollars for this? I wanted to ask you all before I asked the dealership. Thanks.
UPDATE: The wrong solenoid was replaced in my Cayenne. Porsche realized the problem, owned up to it and fixed it without any addition cost. My local Porsche dealership is always 5 star. My Cayenne is now running like a brand new one and I am a happy camper on this Friday afternoon.
